With the end of the interim code here's a map of most middle housing projects, including SFHs, ADUs, DADUs, since May will be interesting to see if the makeup of the types changes with the permanent code aidanthornsberry.github.io/seattle-hous...

Project proposal using the 3ft setback on lots less than 5,000sqft near frequent transit amendment from AMR

Middle housing project proposal that’s just slightly over the mayor’s proposal at ~1.25 FAR vs mayors 1.2, 6,000 sqft lot

HB 1337 double for sale DADUs already delivering results. 3bd homes for less than 300k to build each in South Tacoma

3 examples on the front page of the PSBJ of the trend of the move of companies from suburban office campuses to downtown Seattle/Bellevue, and the redevelopment of those suburban office campuses to housing

Hollingsworth amendment regarding the donut hole passes. Sounds like she's now changed her mind and wants it to still be upzoned, but as a part of the Central District Urban Center (which she thinks is currently a Neighborhood Center), instead of the Capitol Hill/First Hill Regional Center

There's been some student housing townhomes, which confuse me as a typology. How are apartments in LR zones so not worth it, to the point of building student housing townhomes where apartments are allowed? Ravenna Gardens

What's binding for some middle housing projects isn't setbacks, lot coverage, parking... it's the 5,000sqft impervious surface area limit requiring additional stormwater protection

Bellevue getting a number of big """cottage""" proposals, show me the incentive and i'll show you the outcome!

This is good news. Scissor stairs allow for a much more efficient floor plate in high rise construction. See attached image for comparison (credit letsgola.wordpress.com/2015/02/09/h...)

Be there! Tonight

This didn't happen, to a surprising degree in Seattle. It's common and easy for homeowners to buy and build an ADU with less than 150k of capital, with a number of different financing sources easily available. Once they became legal, the market instantly provided tons of information on how to do it

Identical middle housing projects being built next to each other at the same, but built as separate projects each with their own driveways, because separately they're under 5,000sqft of impervious surfaces, but together they'd be over, triggering stormwater regs

Proposal up for a Roosevelt "Up" house, rip

Meanwhile Seattle has a light rail station that should've opened already, with a freeway lid, and hasn't bothered to upzone it! With no upzoning date set!

I agree with this, isn't the Wall Washington Fund a big tilt towards Seattle? If Washington and Seattle both want payroll taxes, the Seattle one should go on top of the state one, not be a substitute of the state one

The old raincitymaps.github.io map of Seattle land values is old, so I vibecoded a new map. Quite similar, can still see the 85th sidewalk line and sharp zoning lines. Bellevue's downtown zoning falloff is a chokehold

The One Seattle Plan's projection of 120,000 units is completely meaningless. It's not based on zoning, capacity, or a real analysis of project growth, it's just a made up number. Could've just as easily picked 500,000. Seattle could abolish zoning and they could project 120,000 units

The council staffs proposed substitute bill is out and the fix for DADUs rear setback is in it. IMO it's completely illogical to have different setbacks for a 1,200 sqft unit in the form of DADU and a 1,200 sqft unit in the form of a principal dwelling unit. Shows the benefits of random exemptions

Getting phase 2 upzones for Queen Anne as high as possible is critical

Interesting that Wilson is a self-described socialist but AMR, Lin and Foster aren't. Or they just haven't been asked about it?

Should see some middle housing projects going up soon, this guy got a project approved under 2 months

Why do stacked flats when we can do 5 story townhomes 🤔

Harrell won this huge area through running up the margin in two buildings, a new condo building and a retirement community

Just realized that we just had Seattle's second to last election without Ranked Choice Voting in the primary, the last being D5 in 2026. Primaries will have a lot more importance and we could see some new coalitions, will be interesting

Anyone know how cured ballots have broken down in the past? Likely many more Wilson voters out there, but also would expect 65+ voters would be proactive in curing their ballots too

Seattle NIMBYs didn't even put up a fuss around this for Seattle's neighborhood stores, even though it's a pretty direct change to the feel of neighborhoods. One benefit of shoving all amendments into one day of voting where all the nimbys got riled up about trees

This upzone shows that you can just upzone. Harrell, Wilson, can propose legislation to upzone within urban and regional centers at any point, no environmental review or years long public engagement required.

Looking at historical daily counts, the share that the progressive takes typically doesn't go down from here. (Until the tiny updates at the end).

A part of the justification for MHA is that we’d “reassess” when market conditions change, but we’re a year into a complete collapse in permitting and there’s not been reassessing from council, the mayor, or the Office of Housing besides considering abolishing it entirely for lower unit projects

Put together a much more comprehensive map of all middle housing/SFH projects in Seattle since the interim code was passed Interim code has been hugely successful so far, the final code should be even better www.google.com/maps/d/u/0/e...

For anyone looking for numbers for the Seattle mayoral discourse, here's a couple excel screenshots to explain what I would expect out of today's drop, and the fate of the race as a whole. First, a day-by-day projection of where I'd expect remaining ballots to end us up. More details below.

So what's the take on why Eddie Lin demolished Ducksworth

Oh, that's it for Wilson. She lost voteshare between yesterday and today

What explains Harrell-Foster voters? 1. The experience attacks landed 2. People view Nelson as more conservative than Harrell 3. Nelson hasn't benefited from the recent Harrell progressive swing

NIMBY candidate Mark Swanson that was filmed crashing into a neighbors yard drunk and insulting the owner, and whose voter's pamphlet included spelling errors in every sentence, got a huge chunk of voters in Bothell, there is a big nimby faction in the burbs

All of these old townhomes have surface parking navigation, but maintain high lot coverage from upper level jut-outs over the parking. How come that doesn't happen to the same extent newer townhome developments?

The Pro-MHA Seattle Times Editorial board acknowledges that MHA fees get passed onto renters, and supports it because of that, lol.

big day to be a former rite-aid

Lake City has had a rough go of it recently, a closed Fred Meyer's, two closed drug stores, and a closed Aurora Rents. Type of neighborhood that could benefit from a targeted 8 year MFTE exemption with no affordability reqs

Used Claude to create a very very rough map of middle housing projects based on %PA permit application downloaded CSV and project descriptions. Can click on each project to see description and search on Seattle's permit portal. www.google.com/maps/d/u/0/e...

some trad nimbyism from mukilteo

Illinois will becoming the 5th state to eliminate local parking requirements for new development projects near transit, after: —California (assembly bill 2097, 2022) —Colorado (house bill 24–1304, 2024) —Oregon (Land Conservation and Development Commission, 2022) —Washington (house bill 1491, 2025)

Bellevue added cottage housing incentives to it's middle housing regs, and it's getting them, 13 units proposed here in a SF-3 zoned area

this is how single stair enables family-sized homes

Absolutely wild project description, what is this

6 unit stacked flat proposal 👀 It's using the ADU floor area loophole in the interim code so it's 5 units + 1 AADU and a FAR of 1.35. The permanent code doesn't exempt ADUs from FAR but allows 1.6+ FAR by right so this project would be doable.

You can see Seattle and Kirkland's present outlier status on for sale DADUs by sorting new homes on lots less than 4,500 sqft on redfin. This map will change soon!

Seattle passed out of committee one of the strongest middle housing rule sets in the country, here's a breakdown of the changes that will supercharge housing production 🧵 First, Type A accessible units are exempt from floor area limits, lot coverage limits and density limits.
