Here's a fun number for you: San Francisco is on pace to approve fewer than 50 new housing permits this year. For the entire city. And the number of those that are single-family homes? Essentially zero.
Let that sink in. The city that sits at the center of the most explosive wealth-creation engine in human history — AI companies where average comp reportedly tops $1.5 million — has functionally stopped building houses. Not because of some grand policy decision, but because the economics and the bureaucracy conspired to make it impossible.
The data tells a damning story of diminishing returns across every tech cycle. During the dot-com boom, SF peaked at roughly 500 permits per year. The 2010s Facebook-Uber-Airbnb era? About 230. Now, in the age of OpenAI and Anthropic, we can't crack 50. Each boom bigger than the last, each construction cycle smaller.
The 2022 Fourplex Ordinance quietly sealed the coffin. A lot that might sell as a $3 million single-family teardown can now be redeveloped into four condos grossing north of $6 million. No rational developer is building a new house on purpose anymore. And the city's Family Zoning plan from December 2025 specifically targets legacy SFH neighborhoods for conversion, meaning the roughly 75,000 single-family homes standing today aren't just the current supply — they may be the permanent ceiling, and that ceiling could actually drop.
As one SF resident put it bluntly: "Show me the empty lots where people are supposed to build?" Fair point. The city ran out of vacant residential land in the 1970s.
Others argue this is simply how cities work. "No one is building SFH in Manhattan either," noted one local. "The return is higher building multiple units on the same lot. This is how cities always function."
That's true — and it's also the point. If you believe in markets, then this is a market speaking clearly: single-family homes in SF are becoming a fixed, potentially shrinking commodity meeting a massive and growing demand wave. The laws of supply and demand don't care about your feelings or your city supervisor's housing plan.
What's maddening is the self-inflicted nature of the problem. Decades of permitting dysfunction, labyrinthine approvals processes, and layer-cake regulation didn't just slow construction — they effectively killed it. The government didn't ban single-family homes. It just made building anything so painful and expensive that the market routed around it, concentrating wealth into existing homeowners while pricing everyone else out.
For the liberty-minded among us, the lesson is clear: when government makes it nearly impossible to build, scarcity isn't a mystery — it's a policy choice. And the people paying the price aren't tech millionaires. They'll be fine. It's everyone else who gets squeezed.
