San Francisco's high rise sprinkler mandate is still very much a live issue, and this morning's turnout proved it. The city's new Fire Code Technical Advisory Council held its first meeting on Friday, September 18, in Room 408 at City Hall. The room filled up fast. So many owners and residents showed up that the city opened an overflow room in the lobby for everyone who could not get in.
I was there. Here is what you need to know about the mandate, the council, and what comes next.
What Is the San Francisco High Rise Sprinkler Mandate?
Under the San Francisco Fire Code, existing residential high rises must install automatic fire sprinkler systems. The requirement applies to residential buildings with occupied floors more than 120 feet above fire department access, and to buildings with occupied floors between 75 and 120 feet that lack either two fire rated interior exit stairways or a compliant fire alarm system with smoke detection. Most of the affected buildings are older towers built decades before modern sprinkler requirements.
The mandate covers about 126 buildings and roughly 9,000 homes. Most are condominium buildings in the city's Northside neighborhoods, including Nob Hill, Russian Hill, Telegraph Hill, Pacific Heights, and the Marina, and many of the owners are retirees and people on fixed incomes.
What the City's Own Cost Study Found
In August 2026, the Board of Supervisors' Budget and Legislative Analyst (BLA) released its report on retrofit costs, requested by Supervisors Stephen Sherrill and Danny Sauter. The main finding: these buildings are so different from one another that there is no single cost.
The BLA modeled three hypothetical 50 unit buildings and came up with a range of $15,000 to $224,900 per unit.
- Low end: buildings that are already partly sprinklered and have a fire service line, standpipe, and some interior piping in place, with underground utilities that can support a sprinkler system.
- High end: buildings with no fire suppression infrastructure that need a complex, invasive retrofit, especially when owners choose a fully concealed system to avoid exposed piping.
I would not plan around the $15,000 number. It applies only to buildings that already have most of the core infrastructure in place, and very few of the affected buildings fit that description. Once walls and ceilings are opened in an occupied older high rise, with engineering, permits, finish work, and relocation on top of the sprinkler work itself, it is hard to see many buildings coming in anywhere near the low end. It is also worth noting that an earlier 2016 Budget and Legislative Analyst report, as reported by the San Francisco Standard, estimated $113,000 to $300,000 per unit, and construction costs have gone up significantly since then.
Some owners have pointed out that the estimates do not fully account for related work that often comes with opening walls and ceilings in older buildings, such as asbestos and lead paint abatement.
The report also looked at other cities. Most have repealed or scaled back similar mandates. San Diego repealed its ordinance. Houston and San Antonio exempted condominiums. Honolulu and Florida settled on compromises requiring sprinklers in common areas but not inside individual units. San Jose reached full compliance, but only 11 buildings were subject to its requirement.
Water Supply Is the Hardest Problem
One of the biggest challenges discussed at today's meeting is getting enough water to each building. Many of these towers sit on the city's steepest hills, and a sprinkler system needs adequate water pressure all the way to the top floor. Some buildings may need a new fire service line from the street, fire pumps, or storage tanks. Others already have much of that in place.
There is no single solution that works for every building. Supervisor Sherrill made the same point when the BLA report came out, noting that some buildings will take a lot of work just to get water pumped to the top of a hill. That is a big reason costs vary so widely, and a big reason a building by building approach makes sense.
The Current Deadlines
After strong pushback from owners, the city pushed back the original schedule. Under the updated Fire Code, the milestones are:
- January 1, 2032: permit application submitted
- January 1, 2034: water supply and riser installation complete
- January 1, 2035: full sprinkler system complete
Under the old schedule, permit applications would have been due January 1, 2027. The Fire Marshal also keeps the authority to evaluate alternate methods and consider time extensions for individual buildings where appropriate.
What the Technical Advisory Council Does
The Board of Supervisors created the Technical Advisory Council to advise the Board, the Mayor, and the Fire Department on requests for alternate compliance methods, waivers, and extensions. The council is advisory. The Fire Marshal keeps the authority to evaluate alternate methods and grant extensions, but the council's recommendations will shape how those decisions get made.
The council has 11 voting members. Six are appointed by the Board: a property owner or manager, a tenant, an HOA representative, a fire protection contractor, a construction professional, and an architect. The other five represent the Controller's Office, the Fire Department, the Department of Building Inspection, the Public Utilities Commission, and the Board of Supervisors President. At today's meeting, the council voted to elect District 2 Supervisor Stephen Sherrill as chair and Captain Tracy O'Keeffe of the San Francisco Fire Department as vice chair.
According to the agenda for the inaugural meeting, the council members are:
- Seat 1, Property Owner or Building Manager: Robert Eaton
- Seat 2, Tenant: Gayle Geary
- Seat 3, HOA Representative: Ann Miller
- Seat 4, Fire Protection Contractor: Christopher Ingram
- Seat 5, Construction Professional: Brandon Bracamonte
- Seat 6, Architect: awaiting appointment by the Board of Supervisors
- City department seats: Ben Becker, Mark Walls, and Bill Teahan
- San Francisco Fire Department, Vice Chair: Captain Tracy O'Keeffe
- Board of Supervisors, Chair: Supervisor Stephen Sherrill
Key Takeaway: Not Every Building Will Be Treated the Same
The most important point from today's meeting: there will not be a one size fits all answer. Each building will be evaluated on its own, and the Fire Marshal has the authority to decide what provides a reasonable degree of fire protection for that particular building.
That matters. A building with existing fire safety features, a difficult layout, or a real financial hardship may not face the same requirements as the building next door. For owners, it means the details of your building now count for a lot: current alarm and detection systems, exit stairways, construction type, water supply, and what a full retrofit would actually cost. Buildings that document those facts well will be in a much stronger position when their case comes before the Fire Marshal and the council.
Owners Told the Council: We Can't Absorb Another Mandate
Financial hardship was a major theme of public comment. Many owners explained that this is not the first big bill their buildings have faced. In recent years many of them have already paid for seismic retrofit work, fire alarm system upgrades, and balcony inspections and repairs, often through special assessments on top of regular HOA dues.
Their message was simple: stacking a sprinkler retrofit on top of all of that is not feasible for many households, especially retirees and owners on fixed incomes.
That testimony matters, because hardship is exactly what the council is supposed to define. How the council treats buildings that have already invested heavily in fire and life safety upgrades will be one of the most important questions to watch between now and December 17.
Owners Want the Fire Data
Owners also asked a pointed question: how many people have actually died in fires in San Francisco's older concrete and steel high rises?
It is a fair question, and it goes to the heart of the debate. Concrete and steel towers are built from noncombustible materials, which is very different from wood frame construction. Owners want to see the fire history for the buildings covered by the mandate before being asked to spend up to six figures per unit. In my own research, I have not found that data in the public materials on the mandate, including the news coverage of the BLA's cost study.
If the council is going to weigh cost against safety, owners are right to expect real numbers on both sides. I will be watching to see whether the Fire Department or the council puts that data on the record.
Where Do Residents Go While the Work Is Being Done?
Another question raised at the meeting has no good answer yet: where do people live while their building is being retrofitted? Installing sprinklers in every unit of an occupied high rise means opening walls and ceilings, and in older buildings that can also mean asbestos and lead paint abatement. Depending on the scope of work, many residents may not be able to stay in their homes while it is underway.
For condo owners, that means paying for somewhere else to live on top of the retrofit assessment itself.
Some of the affected buildings are rental apartment buildings, and there the problem is even harder. Under the San Francisco Rent Ordinance, tenants who are temporarily displaced for capital improvements are generally entitled to relocation payments and the right to return to their units, and work lasting more than three months requires Rent Board approval. Those costs fall on the owner, and tenants still have to find temporary housing in one of the tightest rental markets in the country.
Timing makes it worse. San Francisco rents have surged over the past year. Zumper reported a 22 percent year over year increase as of June 2026, the largest of any major U.S. city, while CoStar put metro rent growth at nearly 11 percent. Short term housing for a displaced household is more expensive now than it has been in years, for owners and tenants alike.
Displacement costs need to be part of the council's hardship analysis. Any cost estimate that leaves them out is incomplete.
The Clock Is Running: Recommendations Due December 17
The council has 90 days from today's meeting, until December 17, 2026, to make its recommendations. That is a short window to settle some of the biggest questions in this process, including how hardship exemptions will work and what alternative compliance paths will look like.
If you own in an affected building, the next three months are when your input counts most. Attend the upcoming meetings, submit comments, and make sure your HOA or ownership group is organized and speaking with one voice before the recommendations are finalized.
Why Today's Turnout Matters
Owners got this issue in front of the city by showing up: at the town hall last December, at the Land Use Committee hearing in February, and again today. A full room and an overflow room tell the council and the supervisors that owners are still paying attention. The council is where exemption and hardship standards will be written, so this is where the outcome will be decided.
What This Means for Owners and Buyers
Owners: don't sit on this
The 2032 permit deadline sounds far away. It isn't. Engineering, water supply studies, HOA votes, financing, and permitting all take time. Owners in affected buildings should get a professional cost estimate now, look at whether their building has a case for a hardship exemption or an alternative compliance path, and keep following the council's meetings.
Buyers: underwrite the mandate
If you are buying a unit or a building subject to the mandate, the retrofit cost belongs in your numbers. Ask for the HOA's reserve study, any sprinkler estimates, planned special assessments, and meeting minutes that discuss compliance. A building that has already planned for this is a very different purchase from one that hasn't.
Apartment building owners face a different set of costs
For owners of rental buildings subject to the mandate, the retrofit cost is only part of the bill. Temporarily displacing tenants under the Rent Ordinance means relocation payments, lost rent while units are offline, and the logistics of moving rent controlled tenants out and back in. In a market where rents rose sharply over the past year, finding temporary housing for tenants is harder and more expensive than ever. Buyers of these buildings will underwrite all of it, and pricing will reflect it.
This will make condos in affected buildings harder to sell
Most condo buyers are not looking to take on a major construction project. When a buyer sees a building subject to the mandate, they see a potential six figure special assessment, months of construction, and the possibility of having to move out while the work is done. Many will simply pass and buy in a building without that exposure.
Fewer interested buyers means longer days on market and lower sales prices. The buyers who do stay in the game will want a discount for the cost and the uncertainty, and sellers should expect them to negotiate hard. Until the council finalizes its recommendations and owners know what their building will actually be required to do, that uncertainty is likely to push down sales prices in these buildings.
For owners thinking about selling, the practical steps are the same ones buyers will ask about: know where your building stands on the mandate, have the HOA's reserve study, any sprinkler estimates, and meeting minutes ready, and price the unit with the mandate in mind. A seller who is upfront about it will get further than one who waits for the buyer to find it in the disclosures.
