San Francisco Mayor Daniel Lurie’s administration implemented a strict two-hour street ban on large vehicles, pushing hundreds of unhoused individuals out of vehicular encampments and into temporary rehousing programs, but data shows that a significant portion of those housed have ultimately been displaced outside city limits. Fourteen months after the policy took effect, data from the San Francisco Department of Homelessness and Supportive Housing reveals that one-third of the adults and families enrolled in the city’s RV rehousing initiative have ended up living outside San Francisco County, driven away by soaring local rents and a severe shortage of affordable housing.
San Francisco Large Vehicle Ban and Rehousing Data
When Mayor Lurie announced the ban in July, roughly 500 large vehicles served as homes for adults and families unable to afford permanent housing in the city. To mitigate the impact, the Mayor’s office launched the Large Vehicle Refuge Permit Program, offering a temporary six-month parking permit and housing assistance to individuals willing to give up or sell their vehicles.
Between November 2025 and September 2026, the city placed 345 adults and families through the program. Department data shows that 115 of those participants—exactly one-third—landed outside of San Francisco city limits.
Approximately 80 percent of the participants were placed into apartments using federally funded housing vouchers. These temporary rental assistance vouchers last for up to two years, requiring households to initially pay 30 percent of their income on rent while assistance gradually tapers off as income stabilizes.
Rising Rents and the AI Boom Push Voucher Holders Out
San Francisco’s rental market, heavily impacted by the artificial intelligence boom, has driven housing costs to levels that outpace the value of temporary rental vouchers. Ora Prochovnik, director of litigation and policy at the Eviction Defense Collaborative, noted that while larger households receive higher voucher caps, soaring rents mean that assistance programs ultimately "tap out."
"Even if you have a high-paying voucher it will tap out, and you won’t be able to afford units in the city," Prochovnik said.
Data from the Department of Homelessness and Supportive Housing indicates this trend spans beyond the recent RV ban. In 2021, only 22 percent of rapid rehousing voucher holders lived outside San Francisco County. By this year, that figure climbed to 58 percent.
Regional Housing Shortages and Service Provider Limitations
Unlike neighboring Santa Clara and San Mateo counties, San Francisco permits service providers to search up to two and a half hours outside the county boundaries to secure housing for homeless residents using city rental aid.
Deborah Bouk, a spokesperson for the Department of Homelessness and Supportive Housing, stated that placements depend on household preference and generally remain within 50 miles of San Francisco near public transportation to maintain support services.
However, Steve Good, CEO of Five Keys—an organization operating the Bayshore Navigation Center shelter in Bayview and distributing vouchers—explained that utilizing housing outside the city is simply a matter of necessity.
"The capacity is really not there," Good said regarding affordable units within San Francisco. Good added that available options for extremely low-income residents inside the city are frequently restricted to single-room occupancy hotels in neighborhoods like the Tenderloin, which feature high concentrations of drug use. Consequently, many families with children and individuals struggling with substance abuse reject those local placements.
Impact on Unhoused Residents and Future Outmigration
Many RV dwellers who dropped out of the city’s rehousing program or failed to secure temporary parking permits left San Francisco independently. An RV dweller identified as J.P., who declined to provide his last name out of fear of retaliation for illegal parking, stated that he abandoned the city’s rehousing program because he doubted he could afford a single-room occupancy hotel once his temporary rental voucher expired. Following the expiration of his temporary parking permit in July, J.P. relocated his vehicle to Palo Alto.
While city officials initially maintained that individuals wishing to retain their RVs could do so outside San Francisco, the combination of strict parking enforcement, expiring temporary permits, and an inaccessible local rental market has forced a growing number of formerly unhoused residents to leave San Francisco.
