When we pass housing laws allowing people to build new homes, we mean it.
HUGE new Ct. of Appeal decision holds that CA homeowners whose ADU application was denied may sue city for damages. The logic sweeps broadly, probably reaching all housing projects subject to ministerial approval under state law -- and perhaps even more. 🧵/23

We spent $600B - $1.2T in real dollars fixing Y2K. It was a huge effort! The lack of major problems from Y2K was more a result of solid preparation than misplaced fears.
Dario Amodei was so worried about Y2K that his high school teacher still remembers it decades later. He’s been a doomer for much longer than I thought!

There’s a clear choice in this race: I’ve fought to build the homes we need to lower costs. My opponent has only blocked them.

It could not be more stark, according to the data. You could have the hardest-working, most prodigious Congressional representative or the most obstructive. “Based on 84 votes she cast on land use since she joined the board in 2021, Chan was second only to former Board President Aaron Peskin in amassing a record consistently opposed to liberalizing housing regulation.” “From Wiener’s first session in the state Senate in 2017-2018 through the 2025-2026 session, he authored the most bills of any legislator in the chamber, at 186. Of those bills, 97 passed and were signed by the governor — the second-most over that period.” sfchronicle.com/politics/art…

This video has over 1 million views, and I think it’s important to explain what I hope people take away from it. I'm not sharing it to shame the individual. He believes he's acting rationally and in the best interests of his organization within a system that has rewarded this behavior for decades. I'm sharing it to show how our housing permitting system works, where the levers of power are, and how they're used to block the housing we need. The problem isn't just the people pulling these levers. It's a broken system that makes blocking housing so easy. It's time to completely reform Massachusetts' housing systems and eliminate the levers of delay that have been abused for so long.
A Massachusetts country club claims that because its members have been shanking golf balls onto a neighbor’s property for 125 years, it has a legal right to stop that neighbor from building housing… 📍Tedesco Country Club, Marblehead

Really impressed by what Devon and her team have achieved. I can’t wait to visit Esmeralda!
GREAT NEWS: The Council voted to advance Esmeralda's approvals! This was the single most important vote of the project, Oct 14. Adoption of the ordinances is on track for Nov 11 These approvals will unlock tremendous value & opportunity

We know how to make our streets safer, so we did it 600 times. Red light cameras reduce red light running by 80% and T-bone crashes by 65%. Most importantly, they help New Yorkers get home safely. That's why we installed new red light cameras at 600 intersections across the five boroughs to help stop dangerous driving before tragedy strikes, and make our streets safer for everyone who walks, rolls, drives, or takes the bus. nydailynews.com/2026/10/21/n…

We tend to talk about poverty in terms of what people earn. We need to talk more about what it costs to keep a roof over their heads. This research reinforces it: reducing housing costs could lift millions out of poverty. Any serious affordability agenda must start with housing.
"The housing shortage in the United States not only drives up rents, it is also a significant driver of poverty." The @nytimes summarizes my collaboration Pew, which quantifies how high housing costs lead to higher poverty rates for 10 U.S. states. nytimes.com/2026/09/29/reale…

Congress has more appetite for housing action than when BMHNT Act was written: Next Congress, on top of land use scoring tweaks, we should explore a Builder's Remedy to waive local restrictions that physically preclude building to the density promised by the locality to the FTA when a project is scored & funded When a locality wins the CIG grant competition & signs a contract with the federal government, and the feds release a grant on reliance of the allowed densities in the land use plan, it's only fair to enforce that contract on the back end. Localities shouldn't be allowed to win federal funds on a fake promise of allowing certain height, bulk (FAR), & units per acre...only to use obscure poison pills to undermine that promise or renege on the promise altogether
Thrilled to announce today @RepScottPeters, @RepBlakeMoore, @brianschatz, & @Jim_Banks are reintroducing the bipartisan Build More Housing Near Transit Act! The bill protects taxpayers & transit riders alike from federal transit grants to cities that ban housing near transit👇

Rents ate 78% of the growth in California's food aid since 1989. More aid without more homes just ends up as rent.
If California's rents fell to the national average, its poverty rate would drop 30%, Pew finds. Rents absorbed 78% of CalFresh's $13.1B benefit growth since 1989. Austin and Minneapolis saw rents fall about 20% after reforms, Pew says.

Are local rock shows just for us olds now? I went to the Rickshaw Stop last night to see abracadabra, an Oakland band. About 4 people under the age of 35 who weren’t performing attended; plenty of gen-xers. The bands were all local and featured young performers.

SF already provides childcare subsidies for families of 4 making up to $324,200. There is no solution* to family affordability without massively increasing homebuilding, thereby bringing down housing costs. Mayor Lurie has no viable plan to scale homebuilding.
Yesterday, the Board of Education took an important step toward ending the public school lottery and giving families the certainty they need to put down roots in our city. Starting in the 2028–29 school year, families will know which neighborhood public elementary school their children are assigned to based on their home address, while retaining choices that reflect the incredible diversity of San Francisco.  I am also pleased that this direction includes a commitment to ensuring our schools have the resources they need, so parents can feel confident that whichever school their children attend, they will find a welcoming environment where they can learn and thrive. I want to thank the Board of Education and SFUSD leadership, including School Board President Phil Kim and SFUSD Superintendent Maria Su, for helping make San Francisco a city where more families can build their futures.

*I suppose Mayor Lurie could instruct all law enforcement personnel to stand down and then do TikTok videos encouraging drug addicts to move to SF, but that would create other problems for SF families beyond affordability.

Western SF on the street level actually looks like a developing city in Latin America but you pay $2 million to live there.
This is not a neighborhood where you can talk about "gentrification concerns" in future tense

I’m very glad we have a cocktail column in Works in Progress. The rise of teetotalism in places like San Francisco is dangerous to civilization; this feels like a small stand against it. Hopefully we will add non-pretentious writing about wine at some point too.
The new issue of @WorksInProgMag both looks and feels fantastic (they are now using a matte paper instead of glossy). Featured cocktail in this issue: Hanky Panky

People who post BART's cost per unlinked trip "explosion" purport to be fiscally literate watchdogs, but it's the opposite: They don't understand businesses with high fixed & low marginal cost BART spending hasn't spiked; lower ridership just mechanically raised cost per trip
Beautification and further stats forthcoming but doing some research and the top line is this: BART operating expenditures have been flat year over year in real terms since the pandemic. There has not been a cost explosion. Concern about rising costs is mostly money illusion.

CA housing donors often approach CG for informal advisory research on how we still value CAYIMBY's zoning agenda There's more to do, plus SB79 takes full effect in 2031-32; defense til then is essential. The SB1123-684 starter home package is in effect but needs defense too👇
SB 1090 pauses SB 1123 small-home projects in Altadena until early 2030. CA YIMBY's Matthew Lewis says owners who can't afford to rebuild and need SB 1123 must now carry their empty lot for three more years, which may push them to sell. insideclimatenews.org/news/0…

Ballots hit mailboxes soon, and a few hundred doors knocked now can decide close races for pro-housing candidates. Join a YIMBY Day of Action on Oct. 10 or 17 to knock, text, or call and help elect people who will end the housing shortage. cayimby.org/daysofaction/

I’ve been making the same argument for a decade in California - these dyspeptic advocates represent nonprofit and foundation staffers, not a mass constituency. Democrats - the only thing they can hurt is your feelings, and only if you let them!
This is the most important thing policymakers should understand about litigation groups like the Center for Biological Diversity: They are paper tigers. They claim to be mass-membership organizations when in fact they’re just a tiny group of extreme anti-human lawyers.
