Should San Francisco upzone further to meet its state housing targets?

Context

California requires cities to plan for a share of regional housing need, and San Francisco’s state-approved housing element committed the city to rezone for a large number of new homes. The response was the Family Zoning Plan, which allows taller and denser buildings along residential and commercial corridors, concentrated on the west and north sides of the city where zoning had long limited apartments.

The Board of Supervisors passed the plan on December 3, 2025 by a 7-4 vote. Supervisors Rafael Mandelman, Bilal Mahmood, Myrna Melgar, Danny Sauter, Matt Dorsey, Stephen Sherrill and Alan Wong voted yes; Jackie Fielder, Chyanne Chen, Connie Chan and Shamann Walton voted no. The plan creates zoning capacity for roughly 36,000 homes (KQED).

Critics from two directions remain unsatisfied. Some supervisors and tenant advocates warned the plan could fuel speculation, put rent-controlled units at risk of redevelopment and displace small businesses without adequate relocation support. Others argue the plan does not go far enough: a lawsuit filed in 2026 contends the rezoning falls short of what state housing element law requires (Davis Vanguard).

So the discussion is about what comes next: more upzoning, tenant protections layered on top, or time to see what gets built under the current rules. Background is available in zoning reform and housing affordability, and you can find your supervisor in the San Francisco directory.

State law sets a target the city has not yet met

Verified

San Francisco's housing element commits the city to rezone for far more homes than past practice allowed, and litigation filed in 2026 argues the adopted plan still falls short of those obligations. Supporters of going further contend that failing to comply exposes the city to state enforcement and to the builder's remedy, under which projects can bypass local zoning entirely. On that view, additional upzoning on the city's terms is preferable to losing control of project review because the plan was written to the minimum.

Capacity on paper is not housing in the ground

Verified

The plan creates zoning capacity for about 36,000 homes, but capacity is only an upper bound. Construction costs, interest rates and financing conditions determine how much of that capacity is used, and housing analysts have projected the plan may produce fewer homes than the headline number suggests. Supporters of additional upzoning argue that cities therefore need to zone for substantially more than their target, so that even a modest share of feasible sites can deliver the homes San Francisco needs.

The west and north sides can absorb more growth

Verified

The plan focuses on neighborhoods that historically resisted major housing changes, which is also where transit corridors, commercial streets and schools already exist. Supporters argue that continuing to concentrate new housing in the eastern neighborhoods, as San Francisco did for decades, placed the burden of growth on lower-income and immigrant communities while wealthier districts were exempt. Extending upzoning further into those areas distributes both the obligations and the benefits of growth more evenly across the city.

Rent-controlled units are the housing already affordable today

Verified

Opponents on the Board of Supervisors warned that thousands of rent-controlled units could be lost to market-rate redevelopment under upzoning. San Francisco's rent-controlled stock houses many longtime residents at rents far below new construction, and once a building is replaced those tenancies are gone permanently. Critics argue that expanding upzoning before strengthening demolition controls, right-to-return provisions and relocation assistance trades existing affordable housing for future market-rate units that will not serve the same households.

Zoning changes without subsidy will not produce affordable homes

Verified

Critics argue the plan does little to produce genuinely affordable housing and may instead fuel speculation on land values, which raises acquisition costs for nonprofit affordable developers competing for the same parcels. Deeply affordable units in San Francisco require subsidy regardless of zoning, and the city faces budget constraints. Opponents contend that the next policy move should be securing funding for affordable production and preserving existing units, not adding more market-rate capacity to a pipeline that is already underused.

Let the adopted plan be tested before changing it again

Verified

The Family Zoning Plan passed narrowly, 7-4, after a long and contentious process, and took effect only recently. Opponents argue that reopening the zoning map before anyone can observe what gets proposed, financed and built creates planning whiplash for neighborhoods, small businesses and developers alike. Small business owners have already raised concerns about relocation support. A period of monitoring permit applications and construction starts, they contend, would give the city evidence rather than projections for the next round.

Where do you stand?

San Francisco should expand its Family Zoning Plan with additional upzoning to meet its state housing element targets.
