“If you want to understand San Francisco’s self-inflicted housing crisis, look no further than the city’s very first zoning law, commonly known as the Cubic Air Ordinance, which set a disturbing standard for the city’s eventual missteps. Proposed in 1870, during a time of rampant real-estate speculation in a boomtown renowned for its lawlessness, the new law required boarding houses to offer a minimum amount of space per tenant. Officials claimed this would promote safer housing and improve residents’ quality of life, a noble cause for government intervention.
But the law’s true purpose—to criminalize Chinese renters and landlords so their jobs and living space could be reclaimed for San Francisco’s white residents—set an ominous precedent. With the Cubic Air Ordinance, city leaders laid the groundwork for 150 years of exclusionary zoning or land-use policy designed to protect the status quo, rather than responsibly manage growth. Often fueled by racism and greed, the dark history of San Francisco urban planning is a story that’s still being told, its latest chapter being the city’s current housing crisis.
