Councilmember Dionne Foster introduced legislation on 18 September that would cut Seattle’s Mandatory Housing Affordability fee by 80 percent for two years on projects that already hold permits but have not broken ground, and by 60 percent for projects that vest by the end of 2027 — those on condition that at least a quarter of their units have two bedrooms or more.
The fee it cuts is the one that pays for affordable housing. That is the whole argument, in both directions.
The collapse is real and the arithmetic is not published
MHA revenue peaked around $74 million in 2021. In the first eight months of 2026 the city collected roughly $7 million. A fee schedule that produces nothing because nothing is being built is not protecting affordable housing; it is describing a stalled market.
The Seattle Housing Roundtable counts 35 permitted projects, better than 6,000 units, sitting in financing limbo, most of them downtown and in North Seattle. Foster’s case is that 20 percent of something beats 100 percent of nothing.
That case may well be right. It is also unaudited. Nobody at the city has published the figure that decides it: what Seattle nets across the two years — fees forgone on projects that would have been built anyway, against fees collected from projects that only move because of the discount. Until someone shows that subtraction, “we get revenue we would not otherwise get” is a hypothesis with a press release attached.
The carveout is narrow enough to check
Chinatown-International District, the Central District and the Rainier Valley are carved out of the full break, with an exception for a legacy homeowner whose deed has not transferred since 1 January 2026. Two of the 35 stalled projects fall inside that zone. A displacement protection that reaches two projects is a real protection and a small one, and both halves of that sentence are worth saying.
Foster paired the bill with a resolution supporting future inclusionary requirements in Neighborhood Residential zones, which pay no MHA today. That is the trade being offered: a discount now, a wider net later. Later is a resolution, not a law.
Who is not on board
The Housing Development Consortium, which speaks for non-profit affordable builders, pulled its support earlier this year and that is what stalled the mayor’s version. Townhome builders object to the expansion into Neighborhood Residential zones. Mayor Katie Wilson backed the concept, then routed the permanent recalibration to a housing production task force reporting in 2027 — after the temporary break would already be running.
What to watch
Whether the council publishes a net-revenue estimate before the vote, now expected in January 2027. How many of the 35 projects actually break ground, which is the only number that settles the argument. And whether the Neighborhood Residential resolution becomes a bill or stays a sentiment.
