The AI boom is driving San Francisco rents up. City Hall is answering with tenant protections

Mayor Daniel Lurie plans to declare a rent emergency in San Francisco, backing measures to slow evictions as the AI boom pushes housing costs to records. The declaration is symbolic, since it doesn't let him bypass any laws, and he compared it to the fentanyl emergency he declared on his first day in office.

Rent in San Francisco is $4,539, up 28.6% over the past year, the steepest increase of any large city in the country and in our own data.

The number that frames the argument is a different one: 489. That's how many housing units the city has built all year, about 10 per square mile.

What Lurie is backing

The package is mostly about protecting tenants rather than adding housing. Supervisor Jackie Fielder has proposed barring evictions for nonpayment until a tenant owes more than one month's rent. Right now, any unpaid rent can be grounds for eviction. Supervisor Danny Sauter wants to limit combined rent increases to 10% in a single year, preventing landlords from saving up smaller annual increases and imposing them all at once. Lurie is also proposing another $3 million for tenant attorneys and a 25% increase in relocation payments for tenants who are evicted.

The eviction numbers help explain why City Hall is moving. Landlords have filed more than 2,400 eviction cases since January, putting San Francisco on pace for its highest total in a decade, according to the Eviction Defense Collaborative.

The build-versus-regulate split

The bigger disagreement is over whether measures like these can actually bring rents down.

Alex Horowitz, who studies housing at the Pew Charitable Trusts, argues that cities have had more success by making it easier to build. He pointed to Minneapolis, Nashville, and Austin as places where more housing helped keep rents in check. "There are cities that have tried to regulate their way out of the problem," he said. "None of those cities have seen big affordability improvements."

Our data shows a similar contrast. Austin added housing aggressively during its boom and rents are now below their 2022 peak. San Francisco added just 489 units this year while posting the largest rent increase in the country. The comparison is not perfect, but the two markets have moved in very different directions.

That does not mean tenant protections have no value. Making it harder to evict someone who falls slightly behind or limiting a sudden jump in rent can matter a lot to someone already in an apartment. San Francisco also has plenty of longtime tenants in rent-controlled units they could not afford to replace at today's market rate. What those policies cannot do is create more housing, and without more supply there is less pressure on market rents to come down.

Lurie says the city needs both more housing and stronger tenant protections. The difficulty is that the two move on very different timelines. Tenant rules can change quickly. New housing can take years to approve and build, so the policies people notice first are likely to be the ones aimed at renters already in place.

The other side of the argument

Oz Erickson, a developer who sits on the San Francisco Apartment Association board, questions whether the city is facing an emergency at all. His argument is that rents look unusually steep now partly because they fell so much during the early pandemic years. Our monthly data gives some support to that view. San Francisco rent rose from $3,723 in January to $4,539 in July, and part of that jump reflects a market recovering from a much lower starting point.

The problem with treating it only as a recovery is where rents have ended up. They are not simply back to 2019 levels. They are above them. City Attorney David Chiu also says his office has received complaints about landlords raising rents beyond what state law allows, in some cases potentially pushing tenants into arrears that could then be used as grounds for eviction. "There are unscrupulous property owners who are trying to take advantage of this moment," Chiu said.

Fielder's own housing situation shows how difficult the market has become. She represents the Mission District, earns about $180,000 a year as a supervisor, and pays $2,200 for a studio. She recently received notice that she has to move because her landlord's family plans to move into the unit. Fielder described apartment hunting as insane, saying many listings were either scams or beyond what she wanted to pay. If someone earning $180,000 is having trouble replacing a $2,200 studio, it gives some sense of how tight the market has become.

We've been tracking the same pressure through the AI hiring boom in rent topping $4,000, the rise in landlords paying tenants to leave, and the broader debate over whether rent freezes, caps, and algorithm bans lower rent.
