How San Francisco's Housing Crisis Became the Crisis It Is Today

Walk through the Mission District today and you'll see a city transformed beyond recognition from even a decade ago. A one-bedroom apartment in the Mission now averages $3,200 monthly—a figure that would have seemed dystopian in 2010. Yet understanding how we arrived at this moment requires looking back much further than the tech boom of the 2010s.

San Francisco's housing scarcity wasn't inevitable. It was constructed, one zoning decision at a time. The city's 1978 Downtown Plan, meant to manage growth after rapid 1960s expansion, inadvertently locked in scarcity. More consequentially, single-family zoning became the unofficial religion of neighborhoods like Pacific Heights, the Presidio Heights, and the Sunset District. These regulations, designed ostensibly to preserve character, functioned primarily as gatekeeping mechanisms—preventing the kind of density that could absorb population growth.

By the early 2000s, before venture capital remade the city's identity, San Francisco faced a different but related crisis. The dot-com bust had temporarily cooled housing demand, yet the fundamentals remained: we were building roughly 2,000 units annually while demand consistently exceeded 5,000. City Planning's permitting processes moved at glacial speeds. A mixed-use development near the Embarcadero or South of Market faced years of Environmental Impact Reviews, community input sessions, and Board of Supervisors negotiations.

Then came the transformation. Airbnb's founding in 2008, headquartered in the Mission, signaled what was coming. Google's 2012 expansion of its San Francisco office. Uber, Lyft, and dozens of startups followed. By 2015, median home prices had surpassed $1 million. Rents tripled in neighborhoods like SOMA and the Inner Mission within five years.

The city's planning apparatus, slow-moving by design, couldn't keep pace. The market delivered: luxury condos in new developments, sure, but not the affordable units that long-time residents needed. Community opposition to density, entrenched for decades, became fiercer. Neighborhood groups fought projects in the Castro, along Van Ness Avenue, and throughout the Sunset.

By 2020, San Francisco had built fewer units over the prior two decades than cities half its size. Meanwhile, tech workers flooded in. The mathematics of this collision created the crisis we inhabit: stratospheric rents, mass displacement from historically diverse neighborhoods, and a city increasingly monoculture.

Understanding this history matters now as the Board of Supervisors grapples with upzoning proposals and changes to parking requirements citywide. We didn't arrive at this cliff edge through market forces alone. We built it through policy choices—choices that can theoretically be unmade.
