San Francisco Extends High‑Rise Sprinkler Permit Deadline Five Years After Owner Pushback

The San Francisco Board of Supervisors voted March 3 to amend the city’s 2022 high-rise sprinkler retrofit ordinance by extending the deadline to file permit applications by five years, a move Mayor Daniel Lurie proposed in December 2025 after owner backlash. Miller, head of the Fontana West owners association, warned the retrofit burden is severe: “retrofitting her building could cost as much as $300,000 per unit. The main part of the cost, she said, is all the work installing a pumping system and routing the piping needed to distribute water through asbestos filled concrete walls. Residents would likely be displaced for months, she says, to allow the asbestos to be safely controlled and removed.”

The ordinance, Ordinance File 220038, was introduced January 11, 2022 by Supervisor Aaron Peskin with co-sponsors Connie Chan, Rafael Mandelman, Myrna Melgar and Shamann Walton and was adopted by the Board in late 2022. The 2025 San Francisco Fire Code local amendments, reported as effective January 1, 2026, incorporate the amendment language that delays the interim permit milestone while establishing a path for unspecified hardship exemptions and time to study alternatives to full sprinkler systems.

Roughly 9,800 residential units in about 126 pre-1975 high-rise residential buildings are targeted by the retrofit requirement, affecting neighborhoods including Western Addition, Nob Hill, Russian Hill, the Marina, lower Pacific Heights and Telegraph Hill. The ordinance requires automatic sprinklers in every residential unit and building-wide upgrades such as pumps, tanks and new piping networks; the work can involve routing piping through existing concrete that some owners say contains asbestos.

Cost estimates for the work diverge sharply. Contractor Chris Ingram disputed higher figures and has claimed a $60,000 per unit all-in price and offered to do whole-building jobs for about $5 million, while reporting elsewhere cited per-unit estimates of $200,000 to $300,000 and GrowSF placed the citywide bill at roughly $600 million to $3 billion. Advocacy groups framing the mandate as a threat used the slogan “Don’t risk bankrupting and displacing 9,800+ San Francisco families,” arguing many affected residents are elderly or on fixed incomes.

Political maneuvering preceded the March 3 vote. Mayor Lurie introduced December 2025 legislation to delay the program by five years and appoint a feasibility committee; a Board committee approved a five-year pause on interim deadlines in late February 2026. Supervisors Danny Sauter and Stephen Sherrill co-sponsored the delay legislation, and Sauter said, “How we got here is a misuse of trust between residents and government and for my part I'll do everything I can to try to correct that.”

Safety advocates and authors of the original ordinance pushed back. The retired fire official who helped craft the 2022 retrofit ordinance “worries the exemptions could defeat the intent to protect the safety of both firefighters and residents.” GrowSF called for a published cost-benefit analysis and a workable permitting and financing plan before imposing what it called a potential multi-billion-dollar mandate.

Reporting on the final installation deadline remains inconsistent: NBC Bay Area said the amendment keeps the end of 2034 as the installation deadline, while Batlingroup and Nosfsprinklermandate list a final Fire Department approval deadline of 2035. The March 3 Board action creates a five-year window for the mayor’s proposed committee to study alternatives and for owners to seek unspecified hardship exemptions while the larger debate over cost, displacement and safety continues.
