What’s Taking Shape Around Mountlake Terrace Town Center? New Housing and Development After Light Rail

For years, Mountlake Terrace’s future Town Center existed mostly in plans: taller buildings near transit, more housing around 56th Avenue West, new storefronts, better sidewalks, and a downtown that felt less like a collection of low-rise properties and more like a walkable center.

Now the transit piece is real. Link light rail opened in Mountlake Terrace in August 2024, and as of fall 2026 both the 1 and 2 Lines stop at the station. What has followed is not one giant wave of construction, but a series of projects moving through financing, permitting, and site planning around the station and Town Center. Some lots remain empty. Some buildings are already there. Others are getting closer. The interesting part is that the city’s long-planned transit-oriented center is beginning to look less theoretical.

Light Rail Arrived Before the Full Town Center Did

Mountlake Terrace is in a somewhat unusual position because the major transportation investment arrived before much of the surrounding redevelopment. The station sits just west of the Town Center, near Veterans Memorial Park, City Hall, the library, and the 236th Street corridor. Riders can now travel south toward Seattle and Federal Way on the 1 Line or connect directly east toward Bellevue and Redmond on the 2 Line.

That gives Mountlake Terrace a level of regional transit access that would have been difficult to imagine when much of the existing downtown was built. The development around it, however, is still catching up. That makes Mountlake Terrace similar to what is happening around Shoreline’s 148th and 185th light-rail stations, where zoning, infrastructure, and private development are adjusting around rail service that is already operating. Northgate offers another comparison: as we covered in What’s Next for Northgate?, having a station does not instantly create a finished neighborhood. The transformation happens parcel by parcel.

The Long-Term Town Center Plan Is Much Bigger Than What Exists Today

Mountlake Terrace’s Town Center plan is designed around an 82-acre area near light rail, I-5, and the city’s civic core. At full buildout, the City says the plan could accommodate roughly 3,000 additional multifamily homes, about 625,000 square feet of commercial space, more than 6,600 new residents, and nearly 2,000 jobs.

The zoning reflects that ambition. Areas closest to the station can accommodate buildings from six to 12 stories, while other parts of Town Center allow roughly four to eight stories, stepping down toward surrounding residential neighborhoods. That does not mean 12-story buildings will suddenly fill every lot. It means developers have the ability to build at a scale that would have been impossible under older zoning if financing, market conditions, and site constraints make a project workable.

Candela Could Become the Station’s Most Visible New Neighbor

One of the largest proposed projects sits immediately east of the light-rail station at 5901 236th Street SW. Candela Apartments is planned as a roughly 425-unit development with a little over 5,000 square feet of commercial space. Its location matters almost as much as its size: pedestrians leaving the station toward Town Center would encounter the project almost immediately.

As of summer 2026, the project had completed its land-use entitlement process, but the developer was still working to secure financing. That distinction is important. A project can be fully planned and entitled without construction beginning immediately, particularly in a higher-interest-rate environment where large apartment projects are expensive to finance. Candela is therefore one of the clearest examples of what Mountlake Terrace is planning for, while also illustrating why Town Center will emerge gradually rather than all at once.

Mountlake Village Would Replace the Former Roger’s Market Site

A few blocks east, another large vacant property carries a familiar local history. The former Roger’s Market site at 23120 56th Avenue West is planned for Mountlake Village, a mixed-use development with roughly 323 apartments and nearly 6,000 square feet of retail space.

As of August 2026, the project had completed the land-use entitlement process and was moving through civil and building-permit review. If it moves into construction, it would fill one of the more conspicuous open sites directly on 56th Avenue and add both residents and street-level commercial space to the center of town. That combination is important because Mountlake Terrace’s vision is not simply to put apartments near a train station. The stated goal is a mixed-use Town Center where more daily needs, restaurants, shops, services, and public spaces can exist within walking distance.

Terrace Station Is Still Expanding

The existing Terrace Station developments southwest of Town Center already show what higher-density housing near the station can look like. Additional phases are also in the pipeline. Terrace Station 4, proposed at 5906 236th Street SW, would add about 223 apartments, while Terrace Station 5 would add another 65 homes on adjacent property near 236th Street and Van Ry Boulevard.

Those projects were still moving through land-use, zoning, and development-agreement processes during 2026, so they should be viewed as pipeline housing rather than completed development. Taken together with Candela and Mountlake Village, however, they show how much housing capacity is clustered within a relatively small walk of the station. The change is not just about one apartment building; it is about several formerly low-density or vacant sites potentially becoming part of a much denser district.

Main Street Is Supposed to Make the Pieces Connect

Buildings are only part of the Town Center story. The City has spent years working on the Main Street Revitalization project, which is intended to make 56th Avenue West and connecting streets function more like the spine of a walkable downtown rather than simply an arterial through it.

Phase I rebuilt 236th Street between I-5 and 56th Avenue. Phase II focuses on the 56th Avenue corridor and includes wider and more accessible sidewalks, tree wells, bike lanes, lighting, drainage and utility upgrades, updated traffic signals, and changes to the roadway configuration. Earlier City schedules targeted an October 2026 construction start, but as of October 13 the project was still out for bid, with contractor bids due October 21. In other words, the next phase is moving forward, but the physical construction start has slipped behind the City’s earlier target schedule.

That infrastructure matters because adding hundreds or thousands of homes without improving the space between them does not automatically create a walkable Town Center. The City is trying to build the street network, pedestrian environment, and utility capacity that can support the private development expected to follow.

The City Is Deliberately Concentrating More Housing Near Transit

Mountlake Terrace adopted a Housing Action Plan in December 2025 that reinforces the same general direction. Rather than distributing all future growth evenly across the city, the plan emphasizes more apartments, townhomes, and other housing options around Town Center, light rail, and neighborhood centers while also addressing displacement and preservation of existing housing.

That approach is increasingly common along the Link corridor. Shoreline has planned substantial station-area growth, Northgate is replacing large auto-oriented sites with housing, and Mountlake Terrace is positioning its relatively small downtown for much greater density. The details are different in each city, but the common thread is that high-capacity transit is changing where local governments expect future housing to go.

What Does This Mean for Existing Mountlake Terrace Homeowners?

For owners of detached homes around Town Center, the effect is not as simple as “light rail makes values go up.” Proximity to rapid transit can be attractive, and new residents can support more shops, restaurants, and services. At the same time, large construction projects can change traffic patterns, views, parking habits, and the overall feel of nearby streets. A house several blocks from the station on a quieter residential street may appeal to buyers differently than a property directly beside a future apartment project.

The broader Snohomish County housing market also matters. In our recent September Housing Market by the Numbers, Snohomish County active inventory was up more than 44% from a year earlier while pending sales were down about 17%. Our October 2026 Real Estate Market Update showed the same theme: buyers have more choices and sellers face more competition. In that environment, being near light rail can be a meaningful location advantage, but buyers are still comparing the specifics of individual streets, homes, and price points.

More Density Does Not Mean Every Project Gets Built

One of the most important things to understand about Town Center is the difference between zoning capacity, approved projects, and actual construction. The City may allow thousands of new homes, and developers may have detailed plans for hundreds of units, but construction depends on financing, rents, interest rates, material costs, and investor demand.

That is why Mountlake Terrace still has visible vacant lots more than two years after light rail opened. It does not necessarily mean the Town Center plan has stalled. Several of those sites have projects attached to them, but a project can spend years moving through entitlement, permitting, financing, and construction. For homeowners trying to understand what may happen near a particular property, the most useful question is not simply “What is zoned here?” but “What has actually been proposed, approved, financed, or started?”

What to Watch Next

The most visible next step will be whether one of the large mixed-use projects moves from paperwork to construction. Candela would transform the immediate station entrance, while Mountlake Village would change the center of 56th Avenue. Progress on Terrace Station 4 and 5 would add still more housing on the station side of the neighborhood.

The Main Street project is just as important to watch. Once Phase II is awarded and construction begins, residents and businesses along 56th Avenue will see short-term disruption, but the finished street is intended to provide the pedestrian, bicycle, utility, and public-realm improvements needed for a denser downtown. Those public improvements and the private projects are really two halves of the same Town Center strategy.

The Bottom Line

Mountlake Terrace Town Center is not suddenly going to become a miniature Bellevue or downtown Seattle. Its transformation is more incremental than that. But the ingredients are increasingly visible: light rail is operating, zoning allows significantly taller mixed-use buildings, major apartment projects are in the pipeline, and the City is preparing the next round of street and infrastructure improvements.

The biggest change may be what 56th Avenue and 236th Street feel like five or ten years from now. Today, the area still contains a mixture of older businesses, existing apartments, single-family properties, civic buildings, vacant development sites, and a new regional transit station. The long-term plan is to connect those pieces into a denser, more walkable center with thousands more residents and substantially more commercial space.

For homeowners, buyers, and sellers in Mountlake Terrace, that makes Town Center worth watching at the project level rather than just as a broad promise about future growth. Where the next building actually breaks ground, how Main Street construction changes access, and which amenities follow the new housing will determine how quickly the neighborhood begins to feel different.
