This is like the tenth research group using a totally new dataset to reach this same conclusion: building new market-rate housing helps low-income tenants. "These findings demonstrate that housing supply expansions benefit lower-income households through moving chains"

TL;DR: Adding housing actually cuts costs for those who need it most. 📉 Didn't think we needed it, but still grateful for the solid data (again).

An Austin or Minneapolis-scale YIMBY victory in California would cut poverty by as much as the Child Tax Credit Already in Minneapolis, *unsubsidized market rate apartments are affordable at federal LIHTC rents* bsky.app/profile/nisk...

Great analysis here from @edmendoza.bsky.social & @pewresearch.org correcting a poorly framed Georgetown report New housing construction moderates Class C rents the most! <60%AMI families will always need income supports But YIMBYism helps all incomes www.metroabundance.org/adding-more-...

Rents are declining nationwide because the United States is building more housing. www.apartmentlist.com/research/nat...

🚨BREAKING🚨 KATHY HOCHUL AND ZOHRAN MAMDANI ANNOUNCE PUSH TO REFORM OUTDATED “ENVIRONMENTAL REVIEW” LAWS THAT BLOCK HOUSING NIMBYS OFFICIALLY FRAMEMOGGED BY HOUSINGMAXXING GOVERNOR AND MAYOR

One house turns into 17 homes in Seattle. (2014➡️2017)

Many people are saying the public sector should operationalize urban land rents.

Vacancy rate go up, rent go down. Believe it or not, there are dozens of non-profit "housing" organizations who collectively receive hundreds of millions of dollars per year from billionaire philanthropists who simply do not believe the law of supply and demand. www.latimes.com/california/s...

It's funny to me, how many people seem to think that NIMBYism in California is principally a fiscal zoning phenomenon. Basically all of the Los Angeles downzonings were finished by the time Proposition 13 took effect.

I'm standing at the corner of Market & Van Ness in #SanFrancisco, atop a subway station and next to a bus rapid transit stop. Still thinking about the retired planner who vowed to block 984 homes here, so he can preserve a defunct car dealership and his faded memories of a few shows he saw in 1971.

🎯🎯🎯 "If Los Angeles is exempted from SB 79...Metro will continue building expensive infrastructure through low-density neighborhoods while ridership lags, housing costs soar, and access to homes near transit remains scarce. That is not a transit success story. It is the status quo, reinforced."

America has a housing shortage. Every single housing proposal you see that is not "build more housing" will have the primary effect of pushing up the prices of existing housing, and is therefore, in reality, a plan to enrich current homeowners. In conclusion, build more housing.

There are only 2 real policy responses to a housing shortage. You can either get to work building enough housing for everyone or start making a list of the types of people you want to exclude. I know which side I’m on.

Pretty wild that there is no coverage in major American media of what is either the most transformative technological breakthrough since the steam engine or the most embarrassing business failure since the Segway.

Begging and pleading with more blue state politicians to figure this out. There's been a lot of progress, but red states are still on track to outgrow blue states before the next Census. (And no, that is not going to inexorably turn those states blue.)

A heck of a chart: in every single one of the 10 major US cities that built the most housing between 2017 and 2023, rents for older, existing units fell—often by quite a bit.

“Deregulation with socialist branding” is no-sarcasm the most fascinating political development of the last decade. Will this work? Fuck if I know but I’m entranced.

"America’s Housing Crunch Has the Wrong Villain" www.aei.org/economics/am... "Institutional investors aren’t the cause of housing distortions but a response to them."

I would love to see the state become a developer and start building housing itself. Not whatever bullshit study bills have been passed so far.

It’s been half a century and it seems like this still isn’t widely understood. (from Robert Caro, 'The Power Broker', Vintage: 1975, p. 897)

Call it Schrödinger's affordable housing project — both dead and alive at the same time. Now after nearly a decade of dispute the fate of a 120-unit, low-income apartment building along the iconic canals in Venice Beach may affect all development in LA www.politico.com/news/2025/12...

If the worst single-family house in your n’hood costs over $1 million, then your n’hood should be zoned for apartment buildings. (It’s pretty much that simple)

On the theme of, "American planners regulate the wrong things," we should have much stricter regulations on noise-proofing apartments. It's the sort of issue regulation is meant to handle: it's difficult for most consumer to assess it before making a decision, and it really impacts qualify of life.

US building codes requiring two stairs in multifamily buildings: not only worse living environments, but also more dangerous in fires! What a combination.

No such thing as an "Orphan Lot" any more. Single stair stacked flats can fit on small lots (like this 50x70 corner lot). This could be 12 small 1Br, or six family size flats. Just allow 50% lot coverage and 3FSR and away you go.

Your home value appreciation is someone's housing costs

California YIMBY is thrilled to announce our first round of endorsements for the 2026 Assembly election, which are in this thread by district number. If you want to support our political work, please donate to the California YIMBY Victory Fund, which you can do here:

We came pretty close to significantly reforming the commercial portion with 2020's Prop 15, and it's probably about time to try again.

Just got a push poll for CA 2026 governor election… for Evan Spiegel, CEO of Snapchat??

San Francisco just upzoned the Sunset, the Richmond, North Point, and a bunch of the Marina. I truly never thought I'd see the day. Huge congratulations to the local activists at @sfyimby.bsky.social who worked so hard to make this happen.

It’s incredible how innocuous all these ED1 buildings are. Karen Bass really is chasing ghosts by blocking these.

You wanna know what’s safer, more affordable, better for the climate, and more space-efficient than a driverless car? A bus.

tax the empty (lots)

I love how the firefighters union, when confronted with data about the safety of single stair, argue “Well New York and Seattle have good firefighters, unlike here in California where we suck ass at our jobs”

at this point, Los Angeles is the most NIMBY city in the country. I am not a socialist myself, but give me a socialist YIMBY like Zohran or Katie Wilson over a liberal NIMBY like Karen Bass any day of the week.

There’s a wide open lane in the upcoming LA mayoral election for someone is determinedly pro-housing and anti-ICE.

amusing chart. it turns out New York City built more housing units in the 1920s than in the 1970s, 80s, 90s, 2000s, and 2010s put together www.nyc.gov/content/plan...

Yesterday's other big theme, besides how much the electorate hates Trump, is that voters really want more housing built.

one of portland's first downzonings happened on robert moses's recommendation in the 1930s, via a report that argued that banning apartments and limiting density would increase single family home values www.portlandmercury.com/images/edito...

By popular demand, @aceckhouse.bsky.social and I have put together a deep-in-the-weeds explainer on SB 79. Enjoy! substack.com/home/post/p-...

MAJOR NEWS: @GavinNewsom signed SB 79, my bill allowing more housing near public transit — rail, subway, rapid bus. It’s a huge step for housing in California. It’ll create more homes, strengthen our transit systems & reduce traffic & carbon emissions. Thank you, Governor!

Ladies and gentlemen, we did it. SB 79 has been signed.

America is not building enough housing and Americans are facing sky-high housing costs as a result. Today, the Senate took a historic step to change that. The ROAD to Housing Act will help communities – urban, suburban, and rural – build more housing and bring down costs.

Probably dumb as hell to publish this on a Friday afternoon, but the clock is ticking to get @gavinnewsom.bsky.social to sign SB 79. Please share — and, if you're a Californian, please call the governor's office at (916) 445-2841 to ask for his signature. publiccomment.blog/p/newsom-s-f...
