Professional Home Remodeling Services in Mountlake Terrace
Mountlake Terrace is one of the most uniform pieces of post-war housing stock in the region — a planned 1950s suburb built quickly for returning veterans and Boeing workers, and still recognizably that. The houses are consistent and cooperative. What has changed is what the zoning allows.
The 1950s rambler, which is most of the city
Street after street of single-story ramblers on modest, regularly platted lots: two or three bedrooms, one bathroom, a kitchen closed off from the living room, perhaps eleven hundred square feet. Structurally these are excellent remodeling candidates — simple load paths, accessible crawl spaces, straightforward to open up and generally room to extend. Conditions are equally consistent: original or lightly updated electrical service, galvanized supply in the earlier houses, single-pane windows, insulation well below current standards, and asbestos-containing sheet vinyl and ceiling texture that we test before demolition rather than after.
The light rail upzone, which changes the arithmetic
Link light rail now serves Mountlake Terrace, and the city has upzoned substantial areas around the station — materially increasing what many lots can support, in some cases allowing additional units where only a single house was permitted before. For a homeowner considering a DADU, a duplex conversion or a substantial addition this is genuinely important, and often in the owner’s favor. It is the first question we answer on any project here, because the answer has changed recently and working from old assumptions leaves value on the table.
Lake Ballinger, Hall Creek and drainage
Lake Ballinger sits on the city’s southern edge and Hall Creek runs through, and this area has a long, documented history of drainage and flooding problems — lake levels and creek capacity have been the subject of sustained local and inter-city attention. Practically, that means drainage design and impervious-surface limits get real scrutiny here, wetland buffers apply in places, and a project that adds hard surface needs a proper stormwater response rather than a token one.
Small lots
Lots here are modest, so setbacks, coverage and impervious-surface limits do a lot of the deciding. Internal reconfiguration and a well-planned bump-out frequently deliver more than a large addition the lot cannot accommodate.

Remodeling in Mountlake Terrace: What the Area Demands
Mountlake Terrace sits on the plateau between Lynnwood and Shoreline in south Snohomish County, with Lake Ballinger on its southern boundary.
Geography and how it affects a build
The plateau is gently rolling glacial ground with till that drains poorly, so perimeter drainage and downspout tightlining are routine on anything that disturbs grade. Lake Ballinger and Hall Creek bring wetland and drainage constraints, and the area’s flooding history means stormwater is taken seriously. There is little dramatic topography, which makes foundation work and staging straightforward. Mature trees planted in the 1950s are now substantial and affect some site work.
Neighborhood character
Mountlake Terrace is practical, diverse and increasingly sought after — close-in suburbia at prices below Shoreline or Edmonds, now with light rail. The housing is strikingly uniform, which gives the streets a coherent mid-century character. The town center has been substantially redeveloped and the station area is changing quickly, with mid-rise construction replacing surface parking. Many households are long-tenured, so a good share of our work is for owners modernizing a house they have lived in for decades.
Construction considerations specific to Mountlake Terrace
Current station-area zoning first, because it has changed and materially affects what is possible. Drainage and stormwater, given the Lake Ballinger and Hall Creek history. Small lots making coverage and setbacks decisive. Poorly draining till. Asbestos-era materials in the 1950s and 60s stock. Staging is generally easy, with generous streets.

About Mountlake Terrace, WA
Mountlake Terrace was built almost from nothing in a few years. In the late 1940s a developer bought a large tract of logged-over plateau north of Seattle and laid out an entire suburb — streets, lots and a plan for hundreds of modest single-family houses aimed squarely at returning veterans able to use federal mortgage programs. Construction ran through the early 1950s at remarkable speed, and the community incorporated in 1954.
The name combined the nearby lakes with the plateau setting. For decades the city was exactly what it had been designed to be: affordable, uniform, family-oriented suburbia, with the Interurban trail on the old rail alignment and Lake Ballinger on the edge. It also inherited a long-running drainage problem, as the lake and Hall Creek struggled with the runoff from surrounding development — an issue that has occupied the city and its neighbors for many years.
The decisive recent change is transit. Link light rail reached Mountlake Terrace in 2024, and the city has upzoned substantial areas around the station, with mid-rise development now replacing parking lots in the town center. The population is around 23,000. For homeowners the combination is unusually favorable: sound, simple, improvable 1950s houses on lots that in many cases now carry materially more development capacity than they did a few years ago.
Remodeling in Mountlake Terrace — Common Questions
I heard the zoning changed near the light rail station. What does that mean for me?
Link light rail now serves Mountlake Terrace and the city has upzoned substantial areas around the station, materially increasing what many lots can support — in some cases allowing additional units where only a single house was permitted before.
This is the first question we answer on any project here. The answer has changed recently and often in the owner’s favor, so working from old assumptions leaves value on the table.
Mountlake Terrace ramblers are small. Is it better to go up or out?
Both work here, and the lot usually decides. Mountlake Terrace was built as a post-war planned community, so you typically have a compact single-story house on a flat, regular lot with room around it. Going out is simpler construction, keeps you living on one level and avoids touching the roof, but it consumes yard and runs into lot coverage and setbacks.
Going up gets you far more square footage per dollar of foundation, and on these small footprints a second story can nearly double the house. The cost is a bigger structural scope, since the existing foundation and walls have to carry the new load, plus a new stair that has to come out of the existing plan. We price both on your actual house rather than recommending one on principle, because the answer genuinely changes lot to lot.
Why does drainage get so much attention here?
Because Lake Ballinger and Hall Creek have a long, documented history of drainage and flooding problems, and the glacial till across the plateau drains poorly. Stormwater and impervious-surface limits get real scrutiny on projects that add hard surface.
We design drainage as a proper scope item rather than a detail at the end.
Can I build a DADU here?
Quite possibly, and more likely than a few years ago given the station-area upzone. Feasibility depends on lot size, coverage, height, setbacks, sewer capacity, access and any wetland buffer.
We check current zoning for your specific parcel rather than what used to apply.
My lot feels small for an addition. What are the options?
Internal reconfiguration, a modest bump-out within setbacks, or a second story where the foundation supports it. On these lots, setbacks, coverage and impervious-surface limits do a lot of the deciding.
Frequently a well-planned interior reconfiguration delivers more than a cramped addition would.
Do you handle asbestos in these houses?
Yes, through licensed abatement subcontractors, and we test before demolition rather than after. Sheet vinyl and textured ceilings from the 1950s through the 70s are the usual candidates.
A few samples cost very little set against the job, and the alternative is a stop-work halfway through demolition. In Mountlake Terrace’s 1950s ramblers we make a point of checking the original furnace and duct runs, since that is frequently where the material is rather than in the visible finishes.
