With the Manito Six in Spokane, we have proof of concept that stacked flats are viable to develop, give residents a wonderful quality of living, and fit nicely in established neighborhoods. Contact me about bringing stacked flat/middle housing to your neighborhood!
It is not going to be possible to unwind all the ill-conceived damage that this administration has senselessly inflicted through their petty insecurities.

Hegseth, we get it-you weren’t a Scout, could never be an Eagle, so now Scouting has to pay.

U.S. ready to cut support to Scouts, accusing them of attacking 'boy-friendly spaces'
Documents show the U.S. military is planning to sever all ties with the organization formerly known as the Boy Scouts.

I’m sorta obsessed with this hip roof.

Classic Sunday walk + swim!

Easy. 20’ wide units.

My favorite is CM Saka’s amendment that cottage clusters can have a FAR of 2 but could only be two stories. How does that work?

1) end parking minimums and implement parking demand management
2) repurposing the right of way to elevate other forms of travel, especially the connection between planned Centers
3) fund and build every bike lane
4) fund, permit, build homeless housing and 0-60 AMI at faster rate.

I can think of one or two, and they rely on access to incredibly rare properties, like this one where they tore down a church and had to navigate a bunch of environmental hurdles.
Took YEARS, and isn't a template for addressing our housing shortage.

This is what I've heard from people who develop those cottage clusters that people save to their pinterest board!

DADUs are a thing, yes, but cottage housing is total fantasy in Seattle. Minimum lot size is basically an acre.

great news!!!

Our passive house project, Echo on Eastlake, just achieved a 0.37ACH, which is REALLY, REALLY GOOD!

Maybe false alarm! The fix is in the works!
Seattle is killing off DADUs unless you have an alley!

Being able to build in the rear yard was how DADUs were possible. If you need a 15 foot setback most DADUs will not work!!!

Need a fix before the one seattle plan vote!

I just heard the same, that this provision will get fixed before it kills off DADUs
Hearing this is getting cleaned up when the council passes the final version of updated neighborhood residential zoning on December 16.

Damn, it was part of the original CB 120993 legislation, before the amendments, and none of us understood the implication.
November 17, 2025 at 6:23 PM
which is 15' for 2 units, 10' for 3 or more.
November 17, 2025 at 6:15 PM
And if you don't have an alley, then suddenly the setback for DADUs is 10 or 15'. this is the problem.
November 17, 2025 at 6:08 PM
how did I not see that either!

@mba-ks.bsky.social you might want to look into this!!!
