San Francisco Built 40% Fewer Homes Than Needed — and the Gap With Global Peers Is Getting Harder to Ignore

San Francisco produced approximately 6,000 fewer housing units annually than its state-mandated target over the past five years, according to figures compiled from California's Department of Housing and Community Development. That 40 percent shortfall — measured against the Regional Housing Needs Allocation figure of roughly 10,000 units per year assigned to the city under the current RHNA cycle — has calcified into one of the most stubborn policy failures in local government.

The timing matters because the California Legislature's 2025 deadline for Bay Area jurisdictions to demonstrate "good faith" compliance under AB 1137 has already passed, and the state's Housing Accountability Unit is now reviewing San Francisco's progress report. Cities that fail to meet production benchmarks risk losing planning authority over certain zoning decisions — a consequence local officials spent much of the spring quietly trying to avoid.

What San Francisco Is Actually Doing

The city is not standing entirely still. Mayor Daniel Lurie, who took office in January 2026 after defeating London Breed, has pushed the Department of Building Inspection to clear a permit backlog that sat at more than 2,400 residential applications as recently as March. The Office of Housing and Community Development is also running the Small Sites Program, which has preserved roughly 1,000 rent-controlled units in neighborhoods like the Tenderloin and Mission District since 2014, though preservation is distinct from new production.

In the Mission, a long-stalled parcel at 16th and South Van Ness — tied up in environmental review for nearly four years — finally received entitlements in May for 168 units, about 30 percent of them designated affordable. In the Sunset District, the rezoning of stretches of Irving Street under the city's Affordable Housing Density Bonus program has unlocked a handful of small infill projects, though neighbors in several blocks have filed discretionary review challenges that can add 18 months to a timeline. The State Lands Commission-adjacent parcels near Pier 70 in Dogpatch represent another potential site, with the mayor's office projecting up to 1,500 units over a decade — projections that have been revised downward twice since 2022.

How Other Cities Are Moving Faster

The comparison with peer cities is uncomfortable reading for San Francisco planners. Vienna's municipal housing authority, Wiener Wohnen, manages roughly 220,000 subsidized apartments and delivers between 7,000 and 9,000 new public and subsidized units each year for a city of roughly 2 million people — a per-capita production rate that dwarfs anything in the Bay Area's pipeline. Singapore's Housing Development Board has consistently housed more than 80 percent of its resident population in state-built flats, using long-term land banking that critics of American urbanism have cited since the 1990s.

Even Tokyo, often invoked in housing policy circles as a counterintuitive success story, is instructive: Japan's national government retains zoning authority and has kept central Tokyo median rents roughly flat in real terms since 2000, even as the city absorbed millions of new residents. San Francisco's median asking rent for a one-bedroom unit stood at $3,150 per month in June 2026, according to Apartment List, down slightly from a 2022 peak but still among the highest in the country.

London offers a mixed case. The Greater London Authority set a target of 52,000 new homes per year under Mayor Sadiq Khan's 2019 London Plan; the city regularly falls to around 35,000, a shortfall of roughly 33 percent — actually better than San Francisco's 40 percent gap on a proportional basis, though London's absolute numbers dwarf the Bay Area's. What London has done differently is consolidate planning approval power at the mayoral level for large sites, reducing the veto points that slow projects in San Francisco's neighborhood-by-neighborhood discretionary review process.

City Hall is expected to take up a revised Housing Element implementation ordinance before the Board of Supervisors' September recess. Advocates at the San Francisco Housing Action Coalition and YIMBY Action are pressing for changes to the discretionary review process that mirror reforms enacted by Oakland in 2023. Whether the Board moves quickly enough to satisfy state reviewers — and to make a dent in a shortfall that has compounded since the late 2010s — will define the next chapter of a crisis that has outlasted several mayoral administrations and any number of announced solutions.
