SF's Migration Surge Is Remaking the City — and Longtime Residents Are Feeling It

San Francisco added an estimated 34,000 net new residents between January 2025 and June 2026, according to preliminary figures from the San Francisco Planning Department — the fastest two-year growth clip the city has recorded since the first dot-com boom. The newcomers are arriving from Houston, New York, Bogotá, and Taipei. They're clustering in SoMa, the Mission, and the rapidly redeveloping Dogpatch corridor. And they are straining a city that was already struggling to house the people who never left.

The timing matters. San Francisco spent the early 2020s watching workers flee to Austin and Phoenix, and local officials spent years trying to coax them back with tax incentives and remote-work policies. Now the AI hiring wave — centered on companies along Market Street and in the Showplace Square district — has reversed the flow faster than the city's infrastructure can absorb. Median one-bedroom rents on Craigslist SF listings hit $3,450 in June 2026, up 18 percent from June 2024. The waitlist for below-market-rate units administered by the Mayor's Office of Housing and Community Development currently runs to roughly 47,000 households.

Neighborhoods Bearing the Brunt

Walk down 24th Street in the Mission on a weekday morning and the old mix of taquerías and paleteros is still there — but so are three new espresso bars that opened since last fall and a co-living facility that converted a former auto-body shop into 62 micro-units. Community organizers at the Mission Economic Development Agency say Ellis Act eviction filings in the 94110 zip code are up sharply again after several relatively quiet years. In the Tenderloin, the Department of Public Health's Street Crisis Response Team has logged a 22 percent increase in call volume since March, partly attributed to displacement pressure pushing vulnerable residents into the neighborhood from elsewhere in the city.

Meanwhile, Muni's 14-Mission and 38-Geary lines — two of the system's highest-ridership routes — are running at or above capacity during peak hours, according to the San Francisco Municipal Transportation Agency's June operations report. BART's Civic Center station recorded its highest weekday ridership since 2019 this past May. The system was not built for this speed of recovery.

What the Data Actually Shows

The Planning Department's figures break the new arrivals into two rough groups. About 60 percent hold professional or technical jobs, many hired directly by AI and biotech firms with offices south of Market or in Mission Bay. The remaining 40 percent are lower-income migrants, including a significant number of Venezuelan and Central American families resettled through the city's Newcomer Navigation Center on Gough Street, which has operated above its 150-bed design capacity since February. City Controller Ben Rosenfield's office estimated in a May 2026 fiscal impact memo that the migration surge will generate approximately $290 million in additional sales and payroll tax revenue by fiscal year 2027 — but that the cost of expanded shelter beds, school enrollment, and infrastructure maintenance will consume roughly $210 million of that gain.

Housing production has not kept pace. The city permitted 4,100 new residential units in 2025 under the state-mandated Housing Element plan, well below the 10,000-unit annual pace needed to meet the Regional Housing Needs Allocation targets set by the Association of Bay Area Governments. Two large projects on Third Street in Bayview — totaling nearly 800 units — remain stalled in litigation over infrastructure financing.

For residents trying to plan ahead: the Mayor's Office of Housing and Community Development is accepting new applications for its Below Market Rate rental lottery through July 31. Community legal organizations including the Tenderloin Housing Clinic and Causa Justa :: Just Cause are offering free eviction-defense clinics at their Mission and Tenderloin offices on alternating Saturdays through the summer. The city's 311 service line can connect renters with rent-increase counseling in Spanish, Cantonese, and Tagalog. None of this fixes a structural shortage built over decades — but for a family getting a rent hike notice this week, knowing those resources exist is not a small thing.
