The Half We’re Not Telling
There’s a familiar refrain in San Francisco’s housing debate: the city must build 82,000 homes to meet state requirements. It’s repeated like scripture — a mantra of supply, speed, and compliance. But it’s only half the story.
The Planning Department’s new report, Rezoning Capacity Calculations, insists that the Family Zoning Plan is “carefully calibrated to create realistic capacity for 36,200 new housing units, as required under state law.” But even within its own pages, a quieter truth appears:
“Changing zoning to allow more housing doesn’t mean all those units will be built, especially during the Housing Element period, since many sites already have buildings or businesses that are unlikely to change soon… In fact, the City is only allowed to count a fraction of the capacity on those sites.”
The report concedes what experience has already shown — that zoning capacity is not the same as housing production. In past rezonings, only a handful of sites have actually been redeveloped, while many have stayed exactly as they are.
And yet, the Planning Department calls this “realistic capacity,” as if arithmetic alone fulfills the law. What it quietly omits is the other half of that legal requirement: 57 percent of those homes must be affordable, a condition explicitly approved in the state-certified Housing Element.
By leaving affordability out of the equation, the city transforms a legal obligation into an illusion of progress — a plan that meets the letter of the law while abandoning its spirit.
The Mirage of Market Faith
For decades, San Francisco has been told a story: build enough luxury housing, and affordability will “trickle down.” But the results are visible in every eviction, every tent, every working family forced from the city they sustain.
This isn’t a crisis of supply alone. It’s a crisis of distribution and intent.
Developers build when the math works. And the math only works when rents rise. Even the so-called solutions — density bonuses, inclusionary units, in-lieu fees — depend on a system that requires scarcity and exclusion to stay profitable.
That is the quiet contradiction at the heart of our housing politics: we keep trusting a market that cannot, and will not, serve the people who need housing most.
The Arithmetic of Avoidance
Inclusionary programs typically yield 10–15% affordable units at best. That means for every 100 units built, a dozen may reach low-income families — when the law demands that the majority of new homes must.
This isn’t ideology. It’s arithmetic.
The math says that without public investment — without bond funding, without public land, without acquisition programs — the Family Zoning Plan is a promise built on sand. It zones for aspiration, not achievement.
The Politics of Performance
Rezoning has become the city’s favorite form of theater. Maps, meetings, hearings — it all looks like motion, but the motion is mostly sideways.
The real work of housing isn’t permission. It’s production.
And production requires financing equal to our ambition.
Cities like Los Angeles and San Diego have learned this lesson. They paired upzoning with dedicated funding and public land commitments. They didn’t wait for the market to discover its conscience. They governed.
San Francisco has 17,675 affordable units already approved and stalled for lack of financing. We don’t need a new zoning plan to make them real. We need the courage to fund them.
The Illusion of Control
State oversight and the looming threat of “builder’s remedy” lawsuits are real. But compliance is not the same as competence.
A city that builds thousands of market-rate units while leaving affordable projects stranded in the pipeline is not solving its housing crisis — it’s deepening it.
Displacement is not an accident of policy. It’s the predictable outcome of a politics that mistakes paperwork for progress.
If San Francisco wants to keep local control, it must prove it deserves it — not through speed or scale, but through intent.
The Work Ahead
A credible plan for real affordability starts with three commitments:
Create a citywide permanent funding source for affordable housing that can meet the moment, because zoning alone won’t unlock the housing pipeline.
Leverage public land for nonprofit and community-based developers, giving them ground to stand on in a speculative market.
Streamline approvals and expand acquisition funds, so public and nonprofit builders can secure sites before prices spiral out of reach.
These are not radical demands. They are the minimum expression of seriousness.
The Moral Question
San Francisco does not face a technical problem. It faces a moral one.
The Family Zoning Plan may satisfy Sacramento’s procedural checklist, but procedure is not justice. A city that zones without a plan to fund will fail — quietly, bureaucratically, predictably.
We have the resources to house every person who calls this city home. What we lack is the will to direct our abundance toward those the market has abandoned.
Housing abundance will not emerge from deregulation. It will come from governance, investment, and purpose.
Because in the end, the question isn’t whether we will build.
It’s who we will build for.
