Decades of Seattle & King County Home Construction: A Journey Through Time

Each decade of home construction in Seattle and surrounding King County has left its mark on our neighborhoods. Below, we break down the key eras of residential construction, highlight their architectural styles, note where you’ll commonly find these homes, and offer tips for homebuyers. (Sales data reflects the number of homes built in each era that sold in the last 365 days in Seattle vs. all King County.)

Pre-1910: The Earliest Homes (1909 & Earlier)

Overview & Architecture: Seattle’s oldest homes date back to the late 1800s and early 1900s. These include Victorian-style houses and early Craftsman or Colonial homes built as the young city grew. Many were constructed with rich old-growth timber and intricate details. You’ll find clusters of these grand old homes in historic Seattle neighborhoods like Capitol Hill, Queen Anne, Leschi, and West Seattle, as well as classic cottages in Wallingford and Beacon Hill. Outside Seattle, early farmhouses and Victorian homes appear in older King County towns (think of places like Snoqualmie, Enumclaw, or parts of Vashon Island). Despite their age, these Seattle homes are still changing hands – about 411 Seattle homes built before 1909 were sold in the past year, along with 459 across King County, showing the enduring appeal of historic houses.

Seattle Homebuyer Tips: Owning a 100+ year-old home can be rewarding, but do your homework. Many pre-1910 homes have been updated over time – check if the electrical wiring and plumbing have been modernized (original knob-and-tube wiring or lead pipes should be replaced for safety). These homes were built before modern seismic codes, so ensure it’s been retrofitted (anchored to the foundation) to better withstand earthquakes. Also, expect quirks: floors may not be perfectly level and rooms can be smaller or oddly shaped. That said, you’ll also enjoy beautiful craftsmanship – from woodwork to stained glass – that’s hard to find in newer homes. Embrace the charm, but budget for ongoing maintenance on a historic property.

Where to Find: In Seattle, look to areas like Capitol Hill’s mansion district, Queen Anne’s hilltop, or Pioneer Square (for some of the oldest surviving structures) for pre-1900 gems. Early 1900s Craftsman bungalows are common from Wallingford and Ravenna to Mount Baker and West Seattle. In King County, older homes pop up in historic pockets of Renton, Auburn, Snoqualmie, and older farm communities along the valleys.

1910s: Craftsman Bungalows & Early Suburbs

Overview & Architecture: The 1910s saw Seattle bursting at the seams. After the 1909 Alaska-Yukon-Pacific Expo, there was an explosion of Craftsman-style bungalows across the city. These modest, livable homes with low-pitched roofs and broad eaves became Seattle’s signature style. You’ll find hundreds of Craftsman bungalows from this era in neighborhoods such as Wallingford, Ravenna, Mount Baker, Ballard, and West Seattle. Many feature charming front porches, built-in cabinetry, and ample wood details. Seattle sold 488 homes built in the 1910s last year, and 586 were sold county-wide – indicating a lot of these century-old houses are still in circulation.

Outside Seattle, development was sparser in the 1910s, but small towns like Kirkland or Renton have a few surviving homes from this era (often near their old town centers). These homes tend to be Folk Victorian or early Craftsman styles, usually on larger lots.

Seattle Homebuyer Tips: A 1910s Seattle home often means Craftsmanship with a capital C – thick fir floors, real wood siding (usually cedar shingles or clapboard), and charming details. When buying, check for any deferred maintenance: after 100+ years, even well-built houses need periodic refreshing. See if major systems (roof, sewer line, furnace) have been updated recently. Like pre-1910 homes, those from the 1910s may have lead paint (assume any house built before 1978 does) and could have had old wiring (knob-and-tube) – verify if those have been replaced or safely maintained. Many Craftsman homes have unfinished attics or basements; these offer potential for expansion but also check for past renovations done with permits. The good news is these houses were built to last – as one local broker put it, “Most Craftsmen have beautiful woodwork…and open, flowing floor plans… harmonizing with the environment”. With a bit of updating, a 1910s house can gracefully serve today’s lifestyles.

Where to Find: Seattle’s early streetcar suburbs are rich with 1910s homes. Wallingford, for example, is known for its rows of Craftsman bungalows. Phinney Ridge, Green Lake, and University District also have many houses from the 1900–1915 period. In King County beyond Seattle, look for historic homes in older sections of Bothell or Issaquah, or near rail hubs like old Kent – though such homes are fewer in number compared to the city.

1920s: Tudor Revivals & Jazz Age Charm

Overview & Architecture: The Roaring ’20s brought prosperity – and a building boom – to Seattle. About 755 Seattle homes built in the 1920s sold last year (and 908 in King County), making this one of the best-represented eras still on the market. Architectural tastes broadened in the ’20s. In Seattle’s established neighborhoods, you’ll see Tudor Revival homes with steep gables and storybook details, Colonial Revivals with symmetric facades, and plenty of Craftsman and Foursquare houses continuing from the previous decade. Neighborhoods like Queen Anne, Capitol Hill, Montlake, Ballard, and Magnolia saw many handsome 1920s homes rise – from brick Tudors to bungalow courts. These Seattle homes often have brick or stucco exteriors, leaded-glass windows, and elegant built-ins.

Across King County, the 1920s also saw growth in smaller towns (fueled by logging and mining booms). For example, Black Diamond and Snoqualmie have a few surviving worker cottages from the ’20s. Capitol Hill and Queen Anne got some of their iconic Tudor-style mansions in this era, while more modest neighborhoods like Greenwood and Leschi filled in with cozy cottages.

Seattle Homebuyer Tips: A house from the 1920s radiates charm – but may come with “vintage” issues. Plumbing and Electrical: If still original, they’re well past their prime. Many 1920s homes had early electrical systems (knob-and-tube was being phased out but could exist in parts of the house) and galvanized steel plumbing. When touring, ask if these have been upgraded; if not, plan for potential updates (galvanized pipes, for instance, can corrode internally over decades). Structure: These houses typically have plaster-and-lath walls and masonry chimneys. Plaster walls can crack (often just cosmetic), and unreinforced brick chimneys may need bracing or lining. Consider a seismic retrofit as well – houses of this era likely aren’t bolted to foundations unless a previous owner did so (retrofits are common in our area due to earthquake risk). On the bright side, the quality of materials – thick wood, sturdy framing – is usually excellent. Many 1920s homes have withstood Seattle’s climate for a century, which bodes well if you continue to maintain them. Lastly, embrace the style: elements like arched doorways, coved ceilings, and built-in breakfast nooks add value (and a smile to your face each morning).

Where to Find: Seattle’s Queen Anne Hill sports numerous 1920s Tudors and Colonial Revivals (especially on the south slope and in Magnolia too). Montlake is known for its 1920s English cottages. South Seattle’s Mount Baker and Leschi areas also have a trove of 1920s homes, many with lake views. Outside Seattle, check older parts of Kirkland (e.g. Market Street area) or Renton’s North End for occasional 1920s houses.

1930s: Depression-Era Homes & Minimal Traditional Styles

Overview & Architecture: The Great Depression slowed home construction dramatically. Only 275 Seattle homes from the 1930s sold in the last year (and 412 in King County), making these some of the rarer finds. Those that were built in the ’30s tend to be smaller and simpler than the roaring ’20s houses – reflecting leaner times. A common style of the late 1930s is the “Minimal Traditional” house: basically a downsized Tudor or cottage with much less ornamentation. These are often 1–1.5 story houses with simplified lines, sometimes called “wartime cottages” (though built just before WWII). You’ll spot them in neighborhoods that were starting to fill in at the city’s edges – parts of Green Lake, Ravenna, West Seattle (like Delridge), and Rainier Valley. Brick or clapboard exteriors with a simple gable, maybe one charming arch or bay window, are typical of a 1930s Seattle home.

In King County’s smaller towns, very few houses went up in the early ’30s. Construction picked up toward 1937–39 with some government and WPA (Works Progress Administration) influence – for example, a few communities saw small tract homes built for workers or modest developer homes as the economy began recovering.

Seattle Homebuyer Tips: If you’re eyeing a 1930s Seattle home, you’ll likely get a modestly sized property with a straightforward layout (often two bedrooms, one bath originally). These homes often have solid masonry foundations and hardwood floors, but be mindful of updates. Insulation: Many 1930s houses originally had little to no insulation in walls – if it hasn’t been retrofitted, you may find higher heating bills or want to invest in insulation upgrades. Hazards: As with any pre-1940 home, assume lead-based paint is present under layers of newer paint, and be cautious during renovations. Additionally, the late ’30s saw some early uses of asbestos materials (e.g. in insulation, siding shingles, or linoleum adhesive). During an inspection, ask about any known asbestos – remediation is common and manageable, but good to budget for. On the plus side, these homes often have simpler electrical systems than earlier decades (fewer circuits to re-wire) and sometimes already include modern amenities added mid-century (many owners later added forced-air heat, updated the panel, etc.). One tip: these “minimal” Seattle homes are very amenable to expansions – many owners have added dormers or finished basements over time. If you need more space, a 1930s house might have potential to grow with you.

Where to Find: Scattered through Seattle neighborhoods – e.g. Greenwood and Phinney Ridge have some late-30s cottages in among earlier homes. North Seattle (parts of today’s Maple Leaf and Wedgwood) saw a few 1930s builds on remaining lots. Look also at West Seattle’s residential blocks inland from California Ave. In outer King County, 1930s homes are few; you might encounter them in old town centers or rural areas as solitary farm houses or cabins from that era.

1940s: Post-War Bungalows & “War Boxes”

Overview & Architecture: The 1940s were a tale of two halves – wartime (early ’40s) and the post-WWII boom (late ’40s). Seattle, being a center for Boeing and shipbuilding, saw a surge of housing for defense workers. Many simple 1-story or 1½-story houses went up in the early ’40s. Then, after 1945, returning GIs and a booming economy led to mass construction of starter homes. In Seattle, 892 homes from the 1940s sold last year – a big jump from the ’30s – and across King County 1,323 such homes sold, reflecting this boom. A typical 1940s Seattle home is often a “War Box” – a plain, square house with a hipped roof (minimal overhangs to save materials) and efficient layout. Many of these were built in 1943–1945. You’ll find them in neighborhoods like Wedgwood, Maple Leaf, Beacon Hill, and West Seattle’s Arbor Heights – areas that were annexed or developed around WWII.

Another common ’40s style is the Cape Cod or Minimal Traditional cottage, usually with 2 bedrooms, shingled siding, and maybe a dormer window. As the decade progressed, the houses got a bit larger and started resembling early ranch-style homes by 1949 (e.g. ramblers with attached garages began to appear). In King County suburbs, places like Lake City (north Seattle, annexed later), White Center (unincorporated then), Renton, and Mercer Island saw a burst of 1940s development – often housing for workers at Boeing or the shipyards.

Seattle Homebuyer Tips: A 1940s home can be a sweet spot: old enough to have charm, but modern enough to often have standard framing and some built-in closets/appliances. Still, remember these houses are ~75+ years old now. Layout: Many are small by today’s standards (e.g. two bedrooms, one bath, ~1,000 sq ft). If you need more space, check if previous owners already added onto it (finished basement or an attic conversion are common). Upgrades: By now, most 1940s homes have gone through one or several upgrades – for example, electrical systems were usually originally 60-amp service; most will have been upgraded to 100 or 200-amp. Ask about the sewer line – lots of 1940s houses still had clay or concrete sewer pipes which can crack – some may have been replaced with PVC. Also inquire if the home has been bolted to the foundation (many 1940s Seeattle homes still need this seismic retrofit if not done). On the positive side, 1940s construction benefited from better understanding of structural loads: these homes are usually sturdily built with full dimension lumber. Energy Efficiency: Don’t expect great insulation unless retrofitted (insulation wasn’t required in walls; many have had blown-in insulation added later). Windows were single-pane wood; see if they’ve been upgraded to double-pane for comfort. Lastly, lead paint and asbestos: Houses of this era often have asbestos in places like old furnace ducts or floor tiles, and definitely lead paint in original paint layers – both can be dealt with, just be aware for any remodeling plans (and use certified abatement contractors if needed).

Where to Find: In Seattle, look to neighborhoods that developed in the 1940s: Wedgwood is famous – a developer built hundreds of modest wartime houses there in 1944–45 (the neighborhood name even comes from one of the tract names). View Ridge/Sand Point in NE Seattle also has many late-40s homes built for Navy families. South Seattle’s Rainier Beach and Highland Park have 1940s cottages as well. In greater King County, Renton Highlands and Bryn Mawr (Skyway) have clusters of 1940s homes for Boeing workers. Mercer Island’s first big wave of homes came post-1940 with the Lacey V. Murrow Memorial Bridge (1940) making it accessible – so you’ll find 1940s colonials and cottages on the north end of the island.

1950s: The Rise of the Suburbs – Ramblers Galore

Overview & Architecture: The 1950s was the golden era of the American suburb, and King County was no exception. After WWII, families flocked to new subdivisions outside the city core. We see this reflected in the data: while about 701 Seattle houses from the 1950s sold last year, a whopping 1,829 homes built in the ’50s sold across King County – one of the highest of any decade. This is when Bellevue, Shoreline, Renton, and other suburbs exploded with development. The quintessential 1950s home is the ranch-style rambler: a single-story (sometimes with a daylight basement), horizontal house with an open living/dining area and large windows. In Seattle, some neighborhoods like Meadowbrook, Lake City, and parts of West Seattle were filled in with ramblers on generous lots during the ’50s. But most ’50s construction happened outside Seattle city limits at the time: for example, Bellevue’s enormous Lake Hills subdivision opened in 1955 with eventually 4,000 homes built on 1,200 acres – all modest ramblers for young families. Similar tracts appeared in Redmond, Kirkland (e.g. the Rose Hill area), Burien, and Kent.

Architecturally, beyond the basic ranch, the ’50s also gave us split-levels (by late ’50s) and Mid-Century Modern gems. A few custom modernist homes dot Seattle (think of certain Magnolia or Laurelhurst houses built by notable architects), but the average ’50s home was simple and functional. Carports or one-car garages became common (the era of the automobile suburb). Many 1950s houses showcase big picture windows, brick or stone accents on the facade, and oak hardwood floors inside.

Seattle Homebuyer Tips: Buying a 1950s house can be a great entry into owning a detached home – they tend to have larger yards and a straightforward layout. Here are things to watch for:

• Plumbing: Many ’50s Seattle homes originally used galvanized steel pipes for water supply, which by now may be partially clogged with rust. See if the home’s plumbing has been updated to copper or PEX. If not, test the water pressure and be aware a repipe might eventually be needed.
• Electrical: By the mid-1950s, houses typically had grounded outlets and circuit breakers (rather than fuses), but not always – verify the electrical panel capacity. Aluminum wiring wasn’t used yet (that came in the mid-60s), so that’s not an issue here.
• Asbestos: It was common in this era in things like popcorn ceilings (introduced late ’50s), linoleum flooring, exterior siding, or insulation on heating ducts. It’s generally not a deal-breaker – often it’s best left undisturbed or professionally abated during a renovation – but know if it’s present. Seattle home inspectors can sometimes identify suspect materials.
• Layout and Storage: ’50s ramblers often have three bedrooms and one bathroom (or 1.5 baths) on the main level. Closet space can be limited by today’s standards. If you need a primary suite or more baths, you might be looking at adding one. On the upside, expansion is easier since you often have a single level spread on a roomy lot (plenty of room to build out or up).
• Character: Don’t underestimate the appeal of mid-century style. Vaulted open-beam ceilings, huge windows, and integration with the outdoors are features in many mid-century homes. Preserving or restoring these elements (like refinishing original hardwood floors or stone fireplaces) can add value. (Fun fact: In the Pacific NW, 1950s cedar siding – if kept painted – can last a very long time. Some homes still sport their original inch-thick cedar siding that’s aged gracefully.)

Where to Find: In Seattle, head north of 85th Street – Meadowbrook, Wedgwood, Pinehurst – these areas have plenty of mid-century ramblers on large lots, as they were annexed into Seattle in the ’50s and quickly developed. West Seattle’s Fauntleroy and Arbor Heights also have many 1950s homes (some with great Sound views). For even more selection, tour the Eastside: Bellevue’s Lake Hills and Newport Hills, Mercer Island’s mid-island neighborhoods, Edmonds/Shoreline to the north, or West Hill in Kent/Renton – all are filled with classic ’50s suburban homes just waiting for your personal updates.

1960s: Mid-Century Modern & Suburban Boom

Overview & Architecture: If the ’50s were big, the 1960s were bigger – at least outside Seattle. The city itself saw relatively little new single-family construction (Seattle sold only 225 houses from the 1960s last year), while 2,107 1960s-built homes sold across King County. This was the era of major suburban expansion, thanks to new highways (like I-5, I-405, and the 520 floating bridge in 1963) and booming employment at Boeing. Eastside cities like Bellevue, Redmond, and Kirkland grew rapidly in the ’60s. Subdivisions pushed further out, giving us neighborhoods of ranches and split-level homes. The split-level (or split-entry) – where you walk in and must go up half a flight to the living area or down half to a basement – became a staple in late ’60s suburban design.

Architecturally, the Mid-Century Modern style hit its peak in the ’60s. In Seattle, a few neighborhoods like Magnolia and Hilltop (in Bellevue) feature custom modern homes from this era, characterized by floor-to-ceiling windows, open beams, and integration with nature. But the bulk of 1960s homes were tract houses with contemporary or ranch flair. You’ll see long, low rambler profiles and also two-story “Colonial” influenced homes (some developers threw on a colonial façade to ranch layouts – think shuttered windows and columned porches on a boxy plan). Mercer Island and Bellevue’s Somerset/Newport Hills got many larger mid-60s homes catering to executive families. Meanwhile, areas like Juanita in Kirkland, Alderwood in Lynnwood, and Fairwood near Renton filled with more middle-class split-entry homes.

Seattle Homebuyer Tips: When buying a 1960s home, pay attention to a few critical things:

• Electrical Wiring (Aluminum): Here’s a big one. In the mid to late 60s, homebuilders began using aluminum wiring for branch circuits (due to copper shortages). If your prospective home was built roughly 1965–1972, see if it has aluminum wiring. Aluminum can be a fire hazard at connections if not mitigated. Many homes have already had a remediation (special connectors or complete rewiring) – but confirm during inspection. (Nationwide, millions of homes from this era had aluminum wiring.) If it’s present and not addressed, you’ll want an electrician’s opinion; it’s a known issue but solvable.
• Foundation and Structure: By the ’60s, building codes were more standardized. These houses generally have strong foundations and are usually fully bolted down (especially late ’60s builds may already have anchor bolts, though possibly not up to today’s seismic standards). Fewer structural surprises compared to older homes.
• Windows and Insulation: Many 1960s homes came with large single-pane windows (great light, poor efficiency). If still single-pane, budget for higher heating costs or plan to upgrade to modern double or triple-pane windows. Insulation was still minimal – an attic might have a few inches of rockwool or fiberglass, walls often uninsulated unless retrofitted. The first energy codes were voluntary in the late ’70s, so a 1960s house can definitely benefit from insulation top-ups.
• Style Updates: The term “mid-century” is hot now, so if your 1960s home has original features like a low-slung stone fireplace, vaulted ceiling, or cool geometric patterns, consider preserving them. Many buyers love these retro touches. That said, interiors from the ’60s (think pink bathroom tiles, shag carpet) may need cosmetic refresh. Focus on fundamentals first – roof (many 60s homes now need their second or third roof replacement), sewer line (still often concrete lines in this era), and any signs of settling.

Where to Find: Since Seattle proper had limited building in the ’60s, you’ll find most mid-century homes just outside city limits. Shoreline and Lake Forest Park immediately north of Seattle are mid-century goldmines. Bellevue (especially east of 148th Ave and in Clyde Hill/Medina for upscale 60s homes), Mercer Island (mid-island ramblers and modern homes), Redmond (Education Hill started developing then), and Issaquah (older downtown Issaquah Highlands) all have plentiful 1960s inventory. In Seattle, look at areas like Montlake Terrace (technically just outside Seattle in SnoCo) or Maple Leaf for the few in-city examples. Also, West Seattle’s Genesee and Gatewood neighborhoods have some pockets of ’60s splits with great views.

1970s: Split-Entries, “Seattle Slump,” and the Energy Crisis

Overview & Architecture: The 1970s brought a mix of trends. In greater King County, suburban growth continued (about 1,833 King County homes from the 1970s sold last year), although Seattle itself saw very few new houses during this time (148 sales of 1970s-built homes in Seattle). Early in the decade, the local economy was hit hard by the Boeing Bust – unemployment soared and pessimism loomed. (In 1971 realtors even put up a famous billboard that quipped: “Will the last person leaving Seattle – Turn out the lights”.) This slowdown meant less construction in the city. However, by the late ’70s, things picked up again regionally as tech and other industries sprouted.

The residential styles of the 1970s continued the ranch and split-level themes, but with some new twists. The split-entry home (where you enter and face a short staircase) became ubiquitous in suburbia – a practical, if sometimes unloved, design. We also saw the rise of the Northwest Contemporary style: think wood-clad exteriors that blend with the environment, big angular rooflines, and open floor plans. Many NW Contemporary Seattle homes were custom builds in woodsy settings (you’ll find great examples in Bellevue’s Bridle Trails, Mercer Island’s forested lots, or Bellevue’s Somerset hill). Meanwhile, mass developers in areas like Federal Way, Kent, Kirkland’s Finn Hill, and Bothell churned out subdivisions of straightforward 3-bed, 2-bath splits and ramblers, often with a daylight basement. Aesthetic in the ’70s leaned toward natural tones – earth-tone paint, dark brown or red siding, and stone or brick accents.

Another factor in late ’70s construction: the energy crisis (1973 oil embargo) led to more emphasis on energy efficiency. We saw features like more insulation (minimal by modern standards but an improvement) and double-pane windows starting to appear toward the end of the decade.

Seattle Homebuyer Tips: When looking at a 1970s home, consider:

• Design and Light: Some 70s split-levels have a reputation for a choppy layout (you often enter into a foyer and have to go up to main living). If you’re okay with stairs, these Seattle homes can be great value and often have solid square footage. Many have large rec rooms or an extra bedroom downstairs – perfect for a home office or guest. Check if any previous remodels opened up the floor plan (removing a wall can make a huge difference in a 70s split).
• Safety and Systems: As mentioned earlier for the ’60s, aluminum wiring may still be an issue in early ’70s homes (it was used up to around 1972). If the house was built 1970-72, definitely have an electrician evaluate it. By the mid-70s, builders went back to copper wiring. Plumbing: This era might have ABS plastic drain lines (good) but still sometimes galvanized or copper water lines. Also, the late ’70s saw the introduction of polybutylene plumbing in some areas (a gray plastic pipe that later proved faulty). Polybutylene was more common in the ’80s, but just be aware if you see gray pipes – it may need replacing.
• Exterior Materials: A lot of 1970s homes in the Northwest were built with T1-11 plywood siding (vertical grooved panels) or early composite sidings. These can be susceptible to moisture if not maintained. Look for any signs of rot in the siding or around windows – and ensure the gutters/downspouts are managing water well. Also, roof material: many original 70s roofs were wood shake or 3-tab composition, likely replaced by now. If somehow the roof is very old, budget for replacement.
• Cosmetics vs. Fundamentals: Many 1970s interiors are dated (hello, shag carpeting and avocado green appliances!). The great thing is that cosmetic updates – new flooring, paint, fixtures – can transform these homes. Focus on the fundamentals during inspection: does it have a dry basement? Any signs of past water intrusion (some splits have below-grade basements – check for sump pumps or water marks)? Is the furnace or water heater ancient or relatively modern? Replace old thermostats with programmable ones – small upgrades can yield big efficiency in these homes.

Where to Find: In Seattle, a few neighborhoods like Rainier Beach, Arbor Heights, and North Seattle’s Olympic Hills saw some 1970s infill, but truly this was the era of the suburbs. You’ll find 1970s homes abundantly in Eastside cities – e.g. Redmond’s Education Hill (lots of ’70s two-story homes), Bellevue’s Cougar Mountain vicinity (70s contemporaries), Renton’s Cascade area, Kent East Hill, Juanita in Kirkland, and Bellevue’s Crossroads area. Further afield, planned communities like Fairwood (Renton) and Inglewood (Sammamish) got going in the 70s. If you’re looking for that classic Brady Bunch split-level, places like Bothell, Lynnwood, or Renton will have plenty to choose from.

1980s: Modernizing and the Tech Boom Begins

Overview & Architecture: The 1980s brought new energy to the Seattle region. The local economy was diversifying – Microsoft’s move to Redmond in 1986 is a famous milestone – and housing development surged especially on the Eastside. In the past year, about 150 Seattle homes from the 1980s sold, versus 1,863 homes in King County – another stark city/suburb contrast. This era saw the birth of many modern suburbs we know today: Sammamish Plateau, parts of Kent/Covington, Woodinville, etc. The style of homes in the ’80s often falls under the broad category of **“Northwest contemporary” meets builder modern traditional. Many houses were two-story designs with attached two-car garages (the garage-forward design became common). Exterior materials were sometimes experimental – composite wood sidings became popular (more on that in a moment). Inside, layouts became more open and light-filled compared to earlier decades, and homes got bigger on average.

Some distinctive 1980s touches: vaulted ceilings in living rooms, skylights, loft spaces, and big master bedrooms (the term “master suite” really became a selling point in the ’80s). Architecturally, the influence of both modern and past styles created what some call “neo-eclectic” – you might see a Seattle home with a bit of Tudor styling (false half-timber) or a Colonial portico, but fundamentally it’s a contemporary floor plan. This was also the era of the “Seattle Box” revival in city neighborhoods – some new infill homes tried to mimic older craftsman or classic styles to fit in established areas, but these were relatively few.

Seattle Homebuyer Tips: A house built in the 1980s is roughly 40-ish years old now, which means:

• Major systems check: Roofs last about 20-30 years, so an original ’80s roof is long gone – make sure the current roof isn’t nearing end-of-life. Furnaces/AC from the ’80s would also likely have been replaced; if not, they’re due. Likewise, original water heaters are certainly gone.
• Siding Alert – Hardboard/LP: One issue to be aware of: many 1980s homes in the Northwest were built with composite wood siding (brands like Louisiana-Pacific InnerSeal, Weyerhaeuser, etc.). Unfortunately, some of these sidings failed in our wet climate, leading to swelling and rot. There were large class-action lawsuits in the ’90s about this siding. When touring an ’80s house, look closely at the siding condition – if it’s a pressed fiberboard (not fiber-cement like today’s HardiePlank, but a wood composite) and you see bubbling, delamination, or lots of patches, that could indicate the need for a re-siding. Many homeowners have already replaced problematic siding with durable materials (vinyl, Hardie board, etc.), but it’s a key question to ask.
• Plumbing: The late ’70s into ’80s saw widespread use of polybutylene pipes in some homes (more common in East Coast/South, but some Northwest homes have it). Polybutylene is a gray plastic pipe that can degrade and leak over time. If the home has it, a previous owner may have already repiped (given the age). If not, know that it was subject to a class-action settlement in the ’90s and is generally recommended to replace. An inspector will recognize it.
• Asbestos & Lead: By the 1980s, lead paint was no longer used and asbestos use was heavily reduced (though some materials like certain popcorn ceilings or old HVAC tape might still have traces if early ’80s). Generally, 1980s houses are considered free of lead paint legally and have minimal asbestos risk compared to earlier homes – one less worry for remodeling.
• Energy Efficiency: Washington’s first true energy code kicked in around 1986, so late ’80s homes often have decent insulation (for the time) and double-pane windows. However, those early double-pane windows might have failed seals by now (look for fogging between glass panes). If windows are original, you may need to budget for replacements in the future for optimal efficiency.
• Layout and Features: If you care about “flow,” many ’80s Seattle homes actually have pretty good layouts – the era of sunken living rooms and conversation pits was ending, replaced by practical family rooms and kitchens that start to open toward each other. You might still find some wallpaper borders and brass fixtures (hello, 1980s!) but those are easy to update. The bones – often 2×6 wall construction, trussed roofs, etc. – are solid. Additionally, fireplaces in the ’80s could be either masonry or prefab metal inserts; check their condition and if any updates (many have been converted to gas).

Where to Find: Large swaths of Redmond, Kirkland (Kingsgate/Juanita), Bothell, Issaquah, and Kent were built out in the 1980s. On the Eastside, areas like Sammamish Plateau, Bridle Trails, and Edmonds to the north have lots of ’80s homes. In Seattle, neighborhoods such as Crown Hill, Northgate, or Rainier Beach had the occasional ’80s infill house (often a home built on a subdivided lot). Another thing to look for: 1980s condominiums and townhouses, if you’re open to attached living – this was the condo boom era in-city. But for single-family, you’ll likely be looking just outside Seattle in any direction to find the most options from the Reagan years.

1990s: Tech Boom Era – Larger Homes & New Communities

Overview & Architecture: By the 1990s, Seattle’s metro was fully in growth mode. Microsoft and other tech companies were expanding rapidly, Boeing was stable, and the population surged. This decade saw the rise of larger “move-up” homes and new cities like Sammamish (incorporated 1999) blossoming. In the last 365 days, 174 Seattle houses from the 1990s sold and 1,648 houses in all of King County – indicating how much building happened in the suburbs during this time.

Homes in the ’90s tend to be bigger than previous decades. The typical 1990s single-family in a subdivision might be 2,500+ sq ft, two-story, with an attached 2-3 car garage. Styles were eclectic – builders borrowed from Craftsman, Victorian, and Colonial styles, but also built plenty of plain contemporary designs. Features like vaulted entry foyers, master suites with soaking tubs, walk-in closets, and bonus rooms became standard. Many ’90s Seattle homes have open floor plans or at least a more open kitchen/family room concept (a shift from the compartmentalized older layouts).

In Seattle, very few new subdivisions were possible, but we saw individual infill homes and small developments in neighborhoods like Maple Leaf, West Seattle, and Magnolia where old homes were torn down or odd lots developed. The city also saw a lot of townhouse/condo development in the late ’90s (notably in Capitol Hill and Belltown), but those aren’t “homes” in the single-family sense. Meanwhile, outside Seattle: areas like Silver Firs (Everett), Klahanie (Issaquah), East Hill of Kent, Covington, parts of Renton (East Renton Highlands) and Maple Valley sprouted countless new houses. Planned communities withHOAs became common – think winding streets, cul-de-sacs, community parks.

Seattle Homebuyer Tips: A 1990s home is relatively “new” in the grand scheme, but it’s now 25–35 years old, so here’s what to consider:

• Maintenance Catch-Up: Many ’90s homes are on their second owners or beyond. You’ll want to see if key items have been updated: Is the roof original cedar shake or 3-tab comp from the ’90s? If so, it’s likely at end of life – budget to replace or ensure it was replaced recently. Same goes for original HVAC systems – a furnace from 1995 is past typical lifespan. Water heaters from the 90s are certainly due for replacement if not already done.
• Siding and Exterior: The siding issue from the ’80s continued into the early ’90s. By the mid/late ’90s, builders in our area shifted more to fiber-cement (Hardie) and better wood composites. If the house was early ’90s, double-check if it had any class-action siding and if it was replaced. Many were, but some might still have it. Also, exterior paint – houses from this era often used spray-on paint that lasts ~10 years. Hopefully it’s been repainted in the last decade; if not, plan on a paint job to protect that siding.
• Windows: Almost all ’90s homes have double-pane windows; however, the early vinyl windows of that time or aluminum frames might not be as energy efficient as today’s. Check if any seals are blown (cloudy between panes). Replacing windows could be a project down the line, but not as urgent if they’re in decent shape.
• Interior Updates: The ’90s style is coming back in some circles (hello, brass is now “warm metal” chic again!). But realistically, you might want to update things like bathroom fixtures, countertops (tile counters were big in the 90s), etc. The good news is the basic infrastructure – wiring, plumbing, insulation – is modern. 1990s homes usually have grounded outlets everywhere, copper plumbing or durable PEX, and plenty of insulation per code. So you’re mostly looking at updating aesthetics and appliances to today’s standards.
• Space and Layout: If you’re moving up from an older home, a ’90s house can feel very spacious and convenient. They often have a family room off the kitchen, a formal living/dining that sometimes feel underused today, and lots of light (big two-story entry windows were common). Think about how you’ll use the space – some buyers choose to convert that formal living room to an office or playroom, for example.
• Yard & Community: In the ’90s, lot sizes in new developments did start to shrink a bit compared to mid-century lots (land was getting pricier). Don’t expect a half-acre in a subdivision – 6,000 to 8,000 sq ft lots were common. The upside is many neighborhoods have sidewalks, playgrounds, and a community feel. If the home is within an HOA, read those rules to ensure you’re okay with them (they often keep the neighborhood looking tidy, which can protect values).

Where to Find: In Seattle, look at enclaves like Sand Point Country Club area (some 90s infill homes among older ones), or Magnolia’s newer development at Discovery Park (late 90s homes). But the majority will be outside city limits: Sammamish (huge amount of 90s homes on the Plateau), Kenmore (much development in the late 90s), Renton (Fairwood), Federal Way (Twin Lakes area had expansion), and Snoqualmie (which had its first master-planned Ridge starting in late 90s) all present great hunting grounds. If you prefer closer-in, Bellevue had areas like Lakemont and Eastgate see many 90s homes, and Kirkland’s Finn Hill/Juanita area boomed in the 90s as well.

2000s: New Millennium – Bigger, Smarter, Greener

Overview & Architecture: The 2000s (especially before the 2008 crash) were a feverish period of building. In the last year, 548 Seattle homes from 2000–2009 sold and 1,998 homes in King County – representing a lot of relatively young houses changing hands. Early 2000s saw the tail end of suburban sprawl and also the beginning of urban infill in earnest. McMansions, as they’re sometimes called, popped up – large 3000+ sq ft houses on small lots with eclectic styling. At the same time, Craftsman revival homes became a trend – in Seattle, you’d see new construction trying to emulate 1910s Craftsman details (porches, tapered columns) but on a modern, larger scale.

By the mid-2000s, green building and energy efficiency gained focus. Seattle and several cities introduced Built Green programs; some homes from the late 2000s have solar panels, tankless water heaters, or advanced insulation for the time. Architecturally, the late 2000s also birthed the very modern “box” homes in Seattle – square-edged, rooftop deck, lots of glass. But those were few in the single-family realm until the 2010s. In the suburbs, planned communities like Issaquah Highlands and Snoqualmie Ridge were built from scratch in the 2000s with a mix of traditional-looking exteriors and very modern interiors (open concept, great rooms, etc.). This era also saw a boom in townhouses in Seattle – areas like Ballard, Fremont, and Capitol Hill got many 3-story townhomes starting mid-2000s.

Seattle Homebuyer Tips: A 2000s-built home is relatively young – 15 to 25 years old – and likely in the prime of its life. But a few pointers:

• Check for deferred maintenance: During the frenetic building boom, some homes were built by less experienced developers or even DIY builders in the early 2000s. Get a thorough inspection to catch any construction defects (e.g. flashing issues, poor drainage around foundation). Many 2000s Seattle homes have had one owner for a long time and could use a refresh (new paint, carpet, etc.), but major systems should still have life left if maintained.
• Roofs & Exteriors: Composite roofs from early 2000s might be halfway through their lifespan, so see what material it is (architectural 30-year shingles vs. cheap 20-year). Cement fiber siding (HardiePlank) was common and is very durable – just needs paint upkeep. Vinyl siding was also used in some developments; it’s low maintenance but can fade.
• Systems: Likely all copper plumbing and modern electrical with ample circuits – not much to worry there. Some higher-end Seattle homes even have structured wiring (Ethernet, speaker pre-wires) since the 2000s saw the home tech wave begin. One thing – the 2000s was the era of granite countertops and stainless steel as the must-haves. Those kitchen and bath finishes might now feel a bit dated only in style (e.g. dark cherry cabinets were trendy then). However, they are perfectly functional – so you can take your time updating aesthetics while enjoying a relatively new house.
• Efficiency: Houses built in the late 2000s benefited from improved energy codes (Washington State’s energy code ratcheted up in 2006 and 2009). That means decent wall insulation, double-pane windows that likely still have good seals, and often more efficient heating (some homes even had early heat pumps or at least high-efficiency gas furnaces). You’ll probably still want to upgrade to smart thermostats or LED lighting, but you’re not dealing with drafty single-glazed windows or uninsulated walls here.
• Size and Layout: Many 2000s houses are quite large, which is great for a growing family or multi-generational living. Just be conscious of the maintenance – more house = more to maintain (and heat). If it has a big two-story foyer or great room, check the condition of any high-up windows or light fixtures – these can be harder to access for cleaning or bulb changing, a small point but worth noting.

Where to Find: City-wise, Seattle’s North Ballard, Greenwood, and Wedgwood saw quite a few single-family homes built after 2000 (often on subdivided lots or replacing teardowns). The Central District and South Seattle (Columbia City, etc.) also had infill development. For larger subdivisions, you’ll be looking at suburbs/exurbs: Maple Valley, Renton Highlands, Newcastle, Sammamish, Snoqualmie Ridge, Duvall – these areas boomed in the 2000s. Covington and Bonney Lake for more affordable large developments a bit further out. Essentially, if you find a master-planned community with a clubhouse and community pool in King County, there’s a good chance it was built in the mid-2000s.

Modern Seattle home built in the 2000s. Contemporary architecture with large windows and open layouts became more common in this era, especially in custom builds.

2010s: Contemporary Designs & Urban Infill

Overview & Architecture: Coming out of the 2008–09 recession, the 2010s saw a strong rebound in construction by the mid-decade. In Seattle, a wave of development focused on density – lots of townhouses, rowhouses, and small lot homes popped up thanks to zoning changes. Still, 523 standalone Seattle houses from the 2010s sold last year (plus many townhomes not counted here), and 1,516 houses in King County – showing healthy construction.

Design-wise, the 2010s embraced Modern architecture more boldly. The stereotype “Seattle modern box” with a rooftop deck became a common sight in neighborhoods like Ballard, Fremont, and West Seattle. These are typically 3-story, flat roof, lots of glass and metal/wood accents – a departure from the Craftsman aesthetic. At the same time, another trend was the Modern Farmhouse look (more so toward the late 2010s): white board-and-batten siding, black window frames, and rustic wood touches – you’ll see these in higher-end new builds from Bellevue to Enumclaw, blending classic farmhouse and modern simplicity.

Green building went mainstream – many 2010s Seattle homes are certified 4-Star or 5-Star Built Green, featuring high R-value insulation, efficient HVAC (heat pumps, HRVs), and solar-ready designs. Open floor plans became essentially standard – open kitchen/living/dining, with an emphasis on multi-use spaces. Also, the ADU/DADU (accessory dwelling unit) movement gained traction late in the decade – Seattle made it easier to add backyard cottages, so some new homes from the 2010s might have a mother-in-law unit or a rentable studio over the garage.

Seattle Homebuyer Tips: A 2010s house is almost new. Your concerns here are less about age and more about the specific build quality and features:

• Builder Reputation: There was a building boom, and not all builders are equal. Research the builder/developer of the home if possible. Many Seattle infill homes were built by smaller firms – check reviews or ask neighbors about any known issues. A home only ~5-10 years old might still have warranties in effect (some builders offered 10-year structural warranties).
• Settling: Newer homes can settle a bit in their first few years. Look for any cracks in drywall or sticking doors – minor settling cracks are normal, but significant ones should be evaluated. Since these homes are well within code, structural issues are rare, but always good to have an inspection.
• Smart Home Features: The 2010s brought us the smart home wave. Many houses have integrated tech – from wired Ethernet in rooms to security systems, smart thermostats, and perhaps smart appliances. Get a rundown of what’s included (and the login info/devices from the seller at closing!). Sometimes high-tech fixtures can age – e.g. an early 2010s smart fridge may now just be a regular fridge if the software isn’t supported – but wiring for surround sound or internet is a timeless perk.
• Yard & Environment: Newer homes often maximize house size on smaller lots, especially in Seattle. If private yard space is a priority, note how the outdoor area is laid out. Roof decks and balconies became popular to compensate for smaller yards. Check if any maintenance agreements exist (for shared driveways in townhouse complexes, for example). In suburbia, many 2010s homes are in HOAs – read those rules (they can dictate paint colors, fence types, etc., but also maintain community amenities).
• Energy Costs: A huge upside of a 2010s home is energy efficiency. You’ll have modern double or triple-pane windows, high-efficiency furnaces or heat pumps, better insulation, and sometimes solar panels or on-demand water heaters. Expect lower utility bills relative to an older house of the same size. Just remember to change the filters on that fancy furnace/HRV as recommended – high-tech systems need love, too.

Where to Find: Seattle neighborhoods like Ballard, Greenwood, Fremont, West Seattle (Alaska Junction area), and Columbia City saw dozens of old lots redeveloped with new modern homes or townhomes. On the Eastside, Kirkland had a big push to rebuild older homes in Juanita and South Kirkland with new construction. Bellevue’s Bridle Trails and West Bellevue had some older homes torn down for luxury new builds. Large new subdivisions in the 2010s were more limited (land was scarce), but places like Renton (The Landing area), Issaquah (Talus), Maple Valley, and Lake Stevens (in Snohomish County) had new neighborhoods. Also, Black Diamond’s Ten Trails master-planned community began in the late 2010s, creating a small-town environment of all-new homes.

2020s: The Present Day – Trends & What’s Next

Overview & Architecture: We’re only a few years into the 2020s, but already have a significant number of new homes: 1,067 in Seattle and 2,543 in King County (built 2020 or later) sold in the past year – the highest of any category. This reflects both continued construction and the fact that new Seattle homes often turn over quickly to eager buyers.

Current trends in architecture blend modern minimalism with warm touches. The Modern Farmhouse style is extremely popular in suburban builds – you’ll notice many new homes in places like Woodinville, Sammamish, or North Bend sporting white siding, black windows, and a gabled roof form. In Seattle and Bellevue’s luxury market, we see ultra-modern homes with expansive glass walls, rooftop terraces, and even concrete or steel accents – the kind of cutting-edge design featured in architecture magazines.

Another hallmark of current homes is the integration of sustainable and high-tech features. New Washington State codes require robust energy measures – think heat pump heating (many new homes no longer use gas at all), solar-ready wiring, EV charging in garages, and excellent insulation/air-sealing. Many 2020s homes come with smart thermostats, video doorbells, and whole-home Wi-Fi systems from day one.

Seattle Homebuyer Tips: Buying a brand-new (or nearly new) Seattle home is exciting – you get the latest and greatest. But keep in mind:

• Warranty: Most new construction comes with a builder’s warranty (often 1 year general, longer for structural). If you’re buying from the first owner and the house is only a year or two old, see if any warranty transfers or if any known issues were already fixed by the builder. It’s good to get an inspection even on new homes – sometimes little things crop up after a year (nail pops in drywall, a sticky door as the house “breaks in,” etc.).
• Settling & Drying: New houses have a lot of fresh lumber that dries out over time, and they may settle a bit. It’s common to have the builder come back for a one-year warranty visit to fix drywall cracks or re-adjust doors – find out if that was done, or if you’d be responsible for cosmetic touch-ups. Keep an eye on caulking around tubs/sinks as new homes can have a lot of shrinkage of materials in year one.
• HOA or No HOA: Many new suburban developments are in HOAs, which maintain common landscaping, sometimes a community playground/pool, etc. Make sure you review those rules to avoid surprises (some HOAs have rules about holiday decorations, lawn care, etc.). In Seattle, obviously, most new homes are not in HOAs, but new micro-communities (like several homes built on a short private drive) might have a joint maintenance agreement.
• Futureproofing: If you’re buying a 2020s home, you’re likely set on big-ticket items for a good while. It becomes more about personalization. One thing to consider is landscaping – often new homes come with basic young landscaping. Investing in planting trees or improving the yard early on will pay off as they grow. Also, think about window treatments (new homes rarely include blinds) and any upgrades like built-in organizers or shelving – these houses are blank slates ready for your customization.
• Enjoy the Perks: Don’t forget to enjoy what a new home offers – for example, very low maintenance. Everything is up to the latest code: seismic safety, fire safety (hardwired smoke/CO detectors), insulation. You shouldn’t have any big expenses for years. It can be a relief, especially for first-time homeowners, to not worry about an old furnace failing in winter or an unexpected roof leak. Still, establish good maintenance habits: even new houses need gutter cleaning, filter changes, and occasional paint touch-ups to stay pristine.

Where to Find: In Seattle, new single-family homes are often found in neighborhoods like Ballard, West Seattle, Laurelhurst, or any area with older homes being replaced one by one. For larger batches of new homes, look at fringe city areas like Shoreline, Lake City, North Seattle around 125th+, where short plats have turned one big lot into several new houses. Outside Seattle, everywhere – from Covington to Kenmore, new subdivisions or infill are ongoing. Notable hot spots: Kenmore and Lake Forest Park (lots of recent builds on subdivided lots), Issaquah/Sammamish (a wave of high-end new construction on tear-down lots and remaining parcels), Maple Valley (tons of family-oriented new neighborhoods), and outlying towns like North Bend and Monroe, which have embraced new development as buyers seek affordability further out. If you drive through nearly any growing suburb, you’re bound to see new Seattle homes going up – King County’s housing demand ensures the crane and hammer will be busy!

In Conclusion: From 19th-century Victorians overlooking Elliott Bay to twenty-first-century smart homes in the Sammamish hills, Seattle and King County boast a remarkable spectrum of home eras. Each decade’s homes tell a story – of the city’s booms and busts, architectural fads, and evolving lifestyles. Whether you’re drawn to a 1908 Craftsman in Capitol Hill or a 2018 modern in Bellevue, knowing the heritage and typical issues of the era will make you a more informed (and appreciative) homebuyer. Every old house has its quirks, and every new house has its unknowns, but with the right due diligence – and a vision for what a home could be – you can find the era that best matches your heart and needs. Happy house hunting through the decades!
