Two nearly identical bungalows sit four blocks apart in North Admiral. Same 1920s bones, same 5,000-square-foot lot, same steep pitch down toward the water. If you pulled up the sale price on either one today, you would see almost the same number. If you pulled up what each lot is actually allowed to become under Seattle's current zoning code, you would see two different neighborhoods.

That gap is not about condition, view, or square footage. It is about a quarter-mile line that runs through North Admiral and stops well before it reaches most of the neighborhood, because of where the RapidRide bus happens to turn.

The rule nobody has priced in yet

On January 21, 2026, Seattle's permanent middle-housing zoning took effect, replacing the old single-family-only rules across every Neighborhood Residential lot in the city. The baseline now is four units per lot, full stop, no rezone required. Ordinary residential parcels that could only ever hold one house can now legally support a fourplex.

The number jumps to six units, but only under specific conditions: the lot has to sit within a quarter mile of what state law defines as a "major transit stop," or the project has to include two income-restricted units. Seattle's city council finalized this framework as part of the broader Comprehensive Plan legislation passed in December 2025, closing out a process that started with the state's 2023 middle-housing mandate.

Most coverage of this law stops at the citywide numbers. What it skips is that "major transit stop" is a narrow legal term. It does not mean any bus that happens to run down your street. It means light rail stations, RapidRide lines, or a local route with service every fifteen minutes or better during peak commute hours. A lot that is a five-minute walk from a regular Metro bus stop can still be capped at four units, while a lot near a RapidRide stop gets six.

North Admiral sits right on top of that distinction, and almost nobody living there has had a reason to notice yet.

Why the C Line counts and the 128 doesn't

The RapidRide C Line runs through West Seattle via California Avenue and Fauntleroy Way, and its closest stop to North Admiral sits at California Avenue SW and SW Alaska Street, essentially the boundary where North Admiral meets Alaska Junction. That stop qualifies as a major transit stop. A quarter-mile radius drawn from it reaches several blocks north into North Admiral proper.

Keep walking north past that radius and you're back in local-bus territory. Route 128 serves the Admiral District on a standard fixed schedule, not the fifteen-minute-or-better standard the law requires. So does the historic Route 56 pattern that has long connected Admiral to downtown. Neither qualifies as a major transit stop under the statute, no matter how convenient the service feels day to day.

The result is a hard edge, not a gradient. A lot inside the quarter-mile radius can support six units. A lot two blocks past it, with a nearly identical footprint and nearly identical walk to the same coffee shop, is capped at four. Nothing about the second lot looks different from the street. Everything about its long-term value calculation is different on paper.

Where the buffer actually falls in North Admiral

North Admiral is the oldest neighborhood on the West Seattle peninsula, and it shows in the housing stock: a mix of century-old homes, mid-century additions, and newer construction sharing blocks with a genuinely walkable commercial strip along California Avenue SW. Corner lots are common here, often with the kind of broad, well-kept front lawn that reads as classic Seattle curb appeal but also happens to be exactly the shape a builder wants for a multiplex, since more street frontage makes it easier to meet setback and access requirements for three or more units.

The practical effect of the transit buffer is that the corner lots and older homes closest to the Junction border now carry meaningfully more redevelopment upside than architecturally similar lots a few blocks further into the neighborhood's interior. That is not a hypothetical distinction. It is the difference between a lot that pencils for a builder as a six-unit stacked-flat project and one that only supports four units, which changes what an investor can justify paying for the land underneath an aging house, independent of what the house itself is worth.

If you are selling a home that happens to sit inside that buffer, you are sitting on more than a house. If you are buying just outside it, you should know that going in, because the number your agent runs for comparable sales may include homes that had a fundamentally different zoning ceiling.

What this does to the median you're staring at

North Admiral is a small market, and that matters more than it sounds like it should. As of June 2026, the neighborhood's three-month median sale price stood at $1.1 million, up 3.2 percent from the same period a year earlier, with homes typically going pending in about eight days. Other trackers looking at slightly different windows this summer have put the number closer to $1 million, and single-family prices specifically have ranged from the high $600,000s up past $2 million depending on lot and square footage.

That spread is not sloppy data. North Admiral typically sees only a few dozen home sales in a given month, so when even one older house sells to a builder near or above its land value because it happens to sit inside the six-unit buffer, it can pull the whole median with it. In a market this size, a single transaction carries more statistical weight than it would in a larger neighborhood like Ballard or Capitol Hill, which is exactly why the zoning boundary matters more here than the headline price does.

If you are watching the median move month to month and trying to read a trend into it, you are often reading noise generated by which handful of lots happened to close and where they sat relative to that quarter-mile line.

What to actually check before you price or offer

Before you set a listing price or write an offer on an older North Admiral home, a few concrete steps will tell you more than the neighborhood median ever will:

• Pull up the address on Seattle's zoning map to confirm the parcel's Neighborhood Residential designation and check the distance to the nearest RapidRide C Line stop, not just the nearest bus stop of any kind.
• Ask whether the lot qualifies for four units or six under the current code, since that single fact changes how a builder or investor will value the land versus the structure.
• If you're selling a lot with real redevelopment upside, get a sense of what similar-zoned parcels have actually sold for as land, not just what nearby finished homes have sold for as houses.
• If you're buying to live in the home rather than redevelop it, the zoning tier matters less for your day-to-day life, but it will shape what gets built around you over the next decade, including on the lot next door.
• Corner lots and larger parcels near the Alaska Junction border deserve a second look regardless of the house currently sitting on them.

None of this requires a rezone application or a lawyer on day one. It requires knowing which side of an invisible line your address falls on before you anchor to a number.

A few questions we hear

Does this mean my house is now worth less if it's outside the six-unit buffer? Not necessarily. Four units per lot is still a meaningful change from the old single-family-only rule, and plenty of buyers in North Admiral are looking for a home to live in, not a development site. The buffer mostly changes the ceiling for investor and builder interest, which shows up most clearly on older homes on larger or corner lots.

How do I find out which zoning tier my specific lot falls into? The distance to the nearest qualifying major transit stop is the deciding factor, and it has to be checked address by address rather than assumed by neighborhood. This is worth confirming before you set a price or write an offer, not after.

Will more middle housing eventually change what North Admiral feels like? Some change is likely over time, the same way it will be across most of Seattle's Neighborhood Residential zones. North Admiral's mix of historic homes and newer construction has already shown it can absorb gradual change without losing what makes California Avenue's commercial strip work. This law adds another layer to that pattern rather than a sudden one.

If you're trying to figure out what a specific North Admiral address is actually worth under the current rules, or whether a home you're considering sits inside or outside that six-unit line, that's exactly the kind of question worth working through before you list or make an offer.
