Two Zoning Maps, One Street: What Morgan Junction Buyers Are Really Buying Into

October 15, 2026

On 39th Avenue SW north of Morgan Junction, between Holly and Juneau, the two sides of the street have different futures on paper. The City's proposed rezone keeps the east side in Neighborhood Residential and moves the west side to Lowrise 2. West Seattle Blog reported in March 2026 that residents there say builders have already contacted homeowners about buying, before any rezone has been approved.

Buyers looking around Morgan Junction tend to treat that proposed map as the big variable. But the proposal is frozen. The rule that changed what an ordinary West Seattle lot is worth to a builder took effect on January 21, 2026, and it applies to both sides of 39th today.

The rule already in force rewards a lot for holding more homes

Seattle's permanent Neighborhood Residential code replaced the old single-family zoning. It allows the greatest of four homes per lot, one home per 1,250 square feet of lot area for attached or detached units, one per 600 square feet for stacked flats, which can go denser still if they meet certain requirements, or six homes if the lot is within a quarter-mile of a major transit stop or if at least two units are affordable.

Unit count is only half of it. The incentive sits in the floor-area rule. The code ties allowable building size to density, so a lot that holds more homes is allowed far more total square footage. Here is how the City's tiers work out on a 5,000-square-foot lot:

Homes on a 5,000 sq ft lot Density Floor area ratio Maximum floor area
1 1 per 5,000 sq ft 0.6 3,000 sq ft
2 1 per 2,500 sq ft 0.8 4,000 sq ft
3 1 per about 1,667 sq ft 1.0 5,000 sq ft
4 1 per 1,250 sq ft 1.6 8,000 sq ft

On the same dirt, a single house tops out at 3,000 square feet. Four homes can share 8,000. Height follows the same logic. The base limit is 32 feet plus pitched-roof allowances, and it rises to 42 feet if the site plants or keeps enough tree canopy, retains a Tier 2 tree, or puts three or more principal units behind a front setback of at least 20 feet. With three or more units, the required front setback also shrinks from 15 feet to 10.

For a buyer, this means the competition for an older house on a standard lot can include anyone who runs the four-unit math. That has been true since January, with no Council vote still to come.

Three details in the code change the math lot by lot:

  • Lots under 5,000 square feet can have up to 2,500 square feet of floor area whatever the ratio says, which matters on West Seattle's smaller parcels.
  • Density is reduced in proportion to how much of a lot falls within an Environmentally Critical Area, such as a steep slope. On hillside parcels, that can shrink the multi-unit potential.
  • Inside frequent transit service areas, side setbacks drop to 3 feet on lots under 5,000 square feet.

What builders are already paying near Morgan Junction

The clearest local data point is on California Avenue SW just north of Morgan Junction. West Seattle Blog reported in February 2026 that a business building at 5435–5437 California SW was being demolished for 12 townhouses. County Assessor records showed the site sold to a builder for $1.7 million three months earlier. The site plan shows two rows of six homes between California and the alley, with six off-street parking spaces.

That site held a commercial building, not a house in Neighborhood Residential zoning, so it says nothing direct about the January rules. What it does show is what a builder will pay for land near Morgan Junction when the plan is a dozen units, and that buyers of new townhomes here may get one parking space for every two homes.

Farther north, West Seattle Blog reported in June 2026 on an early filing for 11 townhouses on three vacant Harbor Avenue SW parcels. Neither project is tied to the new residential code in the reporting. Both show the type of housing being built on West Seattle infill sites in 2026.

The second map is real, but frozen

The proposal behind the 39th SW dispute is the City's "Centers and Corridors" legislation, sent to the City Council in January 2026. It would rezone Neighborhood Centers, new and expanded Urban Centers, and frequent transit routes to allow more apartments and condos. The City's zoning hub says Council began review in April and paused it in July because of an ongoing appeal of the environmental analysis. The City expects review to restart in early 2027.

Here is the sequence a Morgan Junction buyer is stepping into:

  1. December 16, 2025. Council adopts the One Seattle Plan and the permanent Neighborhood Residential code.
  2. January 21, 2026. Both take effect.
  3. April 2, 2026. Mayor Katie Wilson announces "Taller, Denser, Faster," a broader later zoning effort, with rezone legislation anticipated in 2027.
  4. June 1, 2026. The Washington Court of Appeals revives two challenges to the plan's environmental review and sends them back without ruling on the merits.
  5. July 2026. Council puts Centers and Corridors on hold. On July 29, it votes 5–4 to change the appeal process for future area-wide rezones. The Urbanist reported that the vote did not affect the pending appeals.
  6. August 10, 2026. The Council's comprehensive plan page, last updated that day, says Phase II is on hold and new meeting dates are likely in early 2027.
  7. September 9, 2026. The state Growth Management Hearings Board upholds most of the environmental review but finds its scope inadequate, and gives the City a year to update it.

The Urbanist's September 12 report says the court challenges holding up Phase II are still pending and will likely be decided in King County Superior Court. No new hearing date was reported.

The proposal's West Seattle outline is set even though its zoning is not. The adopted plan names seven West Seattle Neighborhood Centers, including Upper Fauntleroy at 35th Avenue SW and SW Barton, and Fauntleroy, formerly called Endolyne. In 2025 the Council trimmed Morgan Junction's boundary and voted against creating an Alki Neighborhood Center. Morgan Junction remains the West Seattle Urban Center slated to expand. Alki may come back up, because the Taller, Denser, Faster study will revisit nine candidate Neighborhood Centers, Alki among them.

On 39th SW, the gap between the two sides is smaller than it looks

Under the City's District 1 proposal map, Lowrise 2 allows up to four stories. When residents raised the "abrupt zoning edge" on 39th, Brennon Staley of the Office of Planning and Community Development told them the difference was "fairly minor." He noted that four-story stacked flats are allowed in both zones and that the 60-foot-wide street provides "significant separation," according to West Seattle Blog. Residents pointed to the required setback, which is five feet in Lowrise 2 and ten feet in Neighborhood Residential. They also noted the street has no bus service, with the closest route, the 128, on the SW Morgan hill.

That exchange backs up the earlier point. The side of 39th that stays Neighborhood Residential already allows multiple units, and some neighbors there have already built backyard cottages. For someone buying a house on either side, the pending rezone mostly affects setbacks and how fast redevelopment happens. Whether the lot can be redeveloped at all was settled in January.

Why the pressure lands on detached houses

The September 2026 numbers from the Northwest Multiple Listing Service, published October 6, show that the buildable lot is the scarce part of the West Seattle market.

September 2026 Residential median Residential months of inventory Condo months of inventory
West Seattle (NWMLS Area 140) $897,500 3.00 6.87
Seattle $960,000 4.15 8.30
King County $949,975 4.10 7.05

Across the NWMLS service area, inventory in September 2026 hit its highest level since 2014. The 30-year fixed mortgage rate rose from 6.71% on September 3 to 7.03% on September 24, and reached 7.28% in the first week of October. Even so, West Seattle residential sales that closed in September averaged 26 days on market, compared with 35 days across King County.

So the region is cooling, but West Seattle's residential category, which NWMLS reports apart from condos, is still tighter than the city and county around it. These figures can't show that the new zoning moved prices, and nobody has measured that. What the code does change is who can bid on an older house on a full-size lot. Those listings are also the inventory West Seattle has least of.

How to read a listing's zoning before you write an offer

Each of these comes straight from City sources and can be checked for a specific address:

  • SDCI Property Information Map. Shows whether a lot is within a quarter-mile of a major transit stop, which raises the base allowance to six homes, and whether it sits in a frequent transit service area.
  • The City's interactive map of proposed rezones. This is the map the 39th SW residents used to find out what was planned for their block.
  • SDCI's project research tools. Permit history, maps, and downloadable permit data show what has been filed nearby.

This is a description of how the rules work, not legal or investment advice. A land-use attorney or SDCI can confirm what applies to a particular parcel.

Quick answers

Is the Morgan Junction rezone law? No. The One Seattle Plan's center designations are adopted, but the Centers and Corridors zoning that would carry them out is a proposal on hold until at least early 2027.

Can every West Seattle lot hold six homes? No. Six is the base allowance near a major transit stop or when two units are affordable. Elsewhere the minimum is four. Large lots can hold more under the 1,250-square-foot formula, and stacked flats can reach one per 600 square feet.

Does Taller, Denser, Faster have maps yet? Not yet. It is a study direction to the planning office. The materials reviewed name no new heights or West Seattle boundaries.
