The city is spending millions to prevent displacement while decades of limited construction and a new wave of AI wealth keep raising the price of scarce apartments.

San Francisco Mayor Daniel Lurie has declared a “rent emergency” and proposed tens of millions of dollars in tenant assistance as the city’s newest technology boom drives housing costs sharply higher. Anabel Sosa of SFGATE reported Sunday that the median one-bedroom apartment now rents for $4,400, up 25% from a year ago, while the city’s apartment vacancy rate had fallen to about 2% by August. Eviction notices are up 44% this year. 

Lurie’s response includes $54 million in previously available money for rental assistance, subsidies, legal defense and compensation for displaced tenants, along with $27 million in vouchers for 650 extremely low-income households expected to lose federal assistance. His package also backs stronger eviction protections and limits on accumulated rent increases for some rent-controlled tenants. 

Those policies can keep some people housed. They cannot make a $4,400 apartment affordable to someone whose income never rose with the AI economy.

San Francisco’s immediate crisis comes from two forces arriving on top of each other. AI companies and their employees are bringing new demand into the city, often backed by salaries capable of competing aggressively for housing. At the same time, decades of limits on density and slow housing production have left relatively few additional homes available when demand rises.

A city can subsidize a renter faster than it can build an apartment, which makes emergency assistance politically attractive. The money can prevent an eviction this month. It cannot create another unit in a neighborhood where five prospective tenants are competing for the same vacancy.

Economist Jason Ward, director of the RAND Housing Center, told SFGATE that Lurie’s package is primarily about preventing evictions and protecting particularly vulnerable households rather than lowering rents. Tenant advocates and landlord representatives disagree over several parts of the mayor’s approach, but both sides told the publication the city’s affordability problem extends beyond what the emergency package can solve. 

San Francisco’s rent-control system also divides the market. Many older apartments have protections limiting annual increases for existing tenants, while most single-family homes, condominiums and newer buildings operate under different rules. When market rents surge, owners of less-regulated properties can raise prices more quickly, while owners of rent-controlled units have a stronger financial incentive to obtain a vacancy that can be repriced.

The result is a housing market where the value of an empty apartment can diverge sharply from the value of an occupied one.

Earlier Chronicle reporting found eviction notices increased to nearly 1,500 in the most recent 12-month period tracked, while negotiated tenant buyouts rose from about 250 in 2024 to roughly 400 in 2025. Tenant advocates said the number of people seeking eviction help has also risen sharply.

The city’s emergency spending shifts some financial risk away from renters and onto government. Rental assistance allows public money to cover costs households cannot. Legal aid gives tenants more power when landlords seek eviction. Relocation payments soften the consequences when residents are forced to leave.

None of those mechanisms changes the scarcity producing the price.

Lurie has also backed a major zoning overhaul intended to allow denser construction across more of San Francisco, particularly on the city’s west side. That approach operates much more slowly because new zoning still has to produce projects that can secure financing, permits and construction crews before another apartment reaches the market. 

San Francisco is therefore trying to operate two housing policies at once: protect people from the current market and change the rules that created it.

The tension will intensify if the AI economy keeps expanding faster than housing supply. Emergency programs can keep selected households from being displaced, but each new wave of high-income demand will continue bidding against everyone else for the same limited number of homes.

San Francisco may eventually build enough housing to weaken that pressure. Until then, the city will keep spending public money to protect residents from prices created partly by a shortage its own policies helped preserve.
