Zohran Mamdani won the election and Dick Cheney died today. What an awesome day to be a Muslim

California’s Prop 13 was meant to help homeowners. It's the opposite. New research supported by the Progress & Poverty Institute’s Progress of Ideas grant program shows that Prop 13 has deepened inequality and made housing less affordable across Los Angeles County.

#Berkeley Middle Housing upzoning takes effect on Nov. 1, 2025, allowing 8 homes on a typical lot in most of the previously low-density zones in the city, and more if state Accessory Dwelling Unit and Affordable Housing Density Bonus laws are used. Here's a look at some possibilities! 1/

Great @cayimby.bsky.social panel on condo regulation reform and unlocking multifamily starter homes

I just got my hands on a memo I wrote in 2018 for my old boss, back before I found my way into housing policy. #2, #3, #6, and #7 have since been passed because of @cayimby.bsky.social's fantastic team! 😊 Some points didn’t age as gracefully. It was a different time, we were all still learning.

This bill I wrote is now law.

[VICTORY ALERT] Governor Newsom has signed SB 79, which will make it legal to build multi-family housing near high quality transit! Our statement: cayimby.org/news-events/...

SB79 (California) just signed into law

SB 79 and the rest of @cayimby.bsky.social’s bills have been signed by @governor.ca.gov today :)))

it's so crazy that the 1986 tax law that created the Low Income Housing Tax Credit also eliminated accelerated depreciation on rental housing and the results were predictably terrible taxfoundation.org/blog/1986-ta...

California’s registered car count, 36 million, outnumbers the population of every other state.

I can't stop thinking about this. We're pursuing zero fire risk in multifam, while tolerating much more in single-fam. People respond by building and living in single-fam, where they're exposed to not only one of the highest fire death risks in the developed world, but also TONS more car crash risk

Thursday, San Diego Planning Commission decides whether SDSU staff, UCSD Health nurses, and students can live near two trolley stations—or if we keep forcing them to drive from East County. Let's dive into the College Area Plan! 1/9 🧵

Trump 2.0 has really exposed how brittle and broken the West Coast states' tax systems are. WA, OR, and CA all have a 1% property tax cap. WA has a sales tax but no income tax; OR has an income tax but no sales tax. It is not possible to effectively resist Trump without fixing these tax systems.

Gov. Newsom's housing target is 2.5M by 2030, which is broken down to Very Low Income (643K), Low Income (385K), Moderate Income (421K), and Market Rate (1M). We saw roughly 100K housing starts in 2024 but we need 400K+ annually to even have a shot at hitting his goal. SB 79 would definitely help

Gavin Newsom is getting pressure to veto a bill that would legalize housing near train stations. Easy action with huge reward for public transit, renters, & all of California 👇

Rumor is @governor.ca.gov is getting *tons* of pressure from rich donors to veto SB 79. If he caves, we'd be condemned to a permanent housing crisis — and lose 3-5 electoral votes in 2032. Call and tell him you have his back. Our democracy is more important than rich people's views! 👇 #SB79

A bunch of toxic LA NIMBYs are whining about SB 79, the amazing housing bill the CA legislature passed recently. It's on the governor's desk, and reportedly he's getting cold feet. Hey @gavinnewsom.bsky.social, please have some spine on the most important issue in your state. Just sign it.

SB 79 is still on the Governor's desk and I am losing sleep over it. Please send in a call. cayimby.org/call-sb-79/

Blue cities should tear up the roads in front of ICE facilities and then start decades of community engagement and input sessions to rebuild them. Let's harness our core competencies.

Exciting announcement: the Center for Building has hired @pipedreaming.bsky.social as our Director of Plumbing Standards Research and Development! preview.mailerlite.io/emails/webvi...

I was shocked when I heard Scott Wiener say LA City Council's divided SB 79 vote helped convince state reps to vote yes on the bill. So I mapped it - sure looks like he's telling the truth! The only state reps from LA who voted for SB 79 overlap with city councilmembers who supported the bill. A 🧵:

One of the last major developers building condos in California has completely exited the multifamily market nationally. 😔 www.barrons.com/articles/hom...

San Diego is so much more fun than the Bay Area. What do you mean they clubs and food open late on a Wednesday? The streets are packed!

NIMBYs in San Diego rented a charter bus to directly protest me and a few others at an ADU convention. We have troops marching in DC with a fascist taking over right now and this is what matters to them? Also tons of pure gold in this piece: obrag.org/2025/09/ride...

Photos from a lively @yimbytown.bsky.social discussion on how data-driven research can shape effective policy with (L-R): @andersem.bsky.social, @david-garcia.upforgrowth.org, Arthur Gailes, @skarlinsky.bsky.social, @aarmlovi.bsky.social & @muhammadspeaks.bsky.social.

What a fun panel - thanks for the charming leadership & good questions, @muhammadspeaks.bsky.social

Imagine how it'll feel to do condo defect reform ...

SB 79 now stands as the largest pro-housing land-use legislation in this nation’s modern history.

After 8 years, we did it! SB 79, the biggest upzoning bill in state history, just passed the Legislature. Brief 🧵, with some important thank yous. 1/x

LETS GOOOO @cayimby.bsky.social TEAM!!! THE BILL THAT LEAD TO THE FOUNDING OF CALIFORNIA YIMBY HAS FINALLY PASSED AND IS HEADING TO THE GOVERNOR!!! THIS WAS 5-8 YEARS IN THE MAKING!!!

I REPEAT CELEBRATORY DRINKS FOR SB 79 AT OAKLAND’s VAN KLEEF AT 8:27

LETS GOOOO SB 79!!!!!

New Construction Defect research: @ternerhousing.bsky.social "High insurance costs add roughly 2-4% to a condo project’s hard cost. An estimated that 80-85% of the condo projects are sued." Why build condos if it costs more and you have to sit in court? ternercenter.berkeley.edu/blog/the-fin...

Let's call to support more housing near transit (via SB 79) youtube.com/live/tI-hdvC... My representative's voicemail box is full so we need to drown out the NIMBYs who are calling in today. When the voicemail box is full, google your assembly member's other office numbers and call the capitol #

Two homes turn into 19 homes in Queens. (2017➡️2021)

Dont miss @muhammadspeaks.bsky.social on turning research into action!

SB 79 (Wiener) could be heard on the Assembly floor today! NIMBYs are calling and potting against SB 79. Don't let them speak for you - please call and ask your Assemblymember to vote AYE on SB 79, and ask your friends, family, and frenemies to do likewise. cayimby.org/call-sb-79/

Live in the suburbia and tired of traffic? With Senate Bill 79, you will now have the option to live next to a train station. This common sense idea shouldn’t have been so controversial.

Colorado, Montana, Oregon, and Texas had some major reforms this year and haven’t received enough love online. Colorado and Hawaii passed sensible construction defect reforms. Montana and Colorado went for single-stair. What other reforms have we not promoted enough in the housing space this year?

To put this loan amount in perspective: California is spending $500 million to widen a 10-mile stretch of Highway 37 in the northern Bay Area (through a wetland, no less). But $750 million to save the *entire* Bay Area’s transit systems is apparently infeasible.

Wake up it’s a dictatorship.

This is one of the most exciting features of mostly fixing CEQA in cities, we get to see cool projects like this pop up again. People don’t have the risk of years of lawsuits hanging over their heads!

Just a reminder about why building homes near transit is important to so many people.

There aren't many stories that prompt gasps at our editors' daily budget meeting. But this was one.

Here’s the clip of CM Padilla bragging about reducing the size of a 100% affordable housing project in her district and increasing the amount of parking while arguing against the transit oriented upzoning bill SB 79. (ED 1 is an affordable housing program in LA.)

Deporting undocumented immigrants to improve housing affordability is like cutting off your leg to lose weight.
