When a contractor priced a sprinkler retrofit for Royal Towers at 1750 Taylor Street, the estimate came to between $200,000 and $225,000 per unit, or about $100 a square foot. One reason was distance. According to the San Francisco Chronicle's December 2025 report, the building would have to connect to a water supply four blocks away on Columbus Avenue. Renn Rhodes, who lives in the building, told the paper that the city's deadline extension "is not a solution for us."
That figure doesn't show up on any listing sheet. Two condos on Russian Hill can have the same asking price, square footage, and bay view, and one of them can still be heading toward a six-figure building obligation while the other is not. Two rules now set a date for that difference. One is a city fire code requirement whose permit deadline falls on January 1, 2032. The other is a state law signed five days ago whose reserve-funding rules take effect that same day.
A Cost Set by the Building
San Francisco adopted Section 1103.5.4 of its Fire Code in 2022. It requires some existing residential high-rises to install automatic sprinklers. A building is covered if it has an occupied floor more than 120 feet above the lowest level of fire department vehicle access. It is also covered if it has occupied floors between 75 and 120 feet and lacks either two fire-rated interior exit stairways or a compliant fire alarm system with the required smoke detection. Chronicle reporting places most of the affected units in Nob Hill, Russian Hill, the Marina, and Pacific Heights.
The count depends on the source. The Fire Department's preliminary estimate, cited by the Board of Supervisors' Budget and Legislative Analyst in August 2026, is 129 buildings. The Chronicle's September 2026 coverage puts it at 126 high-rises and about 9,000 units.
The cost range is even wider than the count. The Analyst's August 3, 2026 report modeled three hypothetical 50-unit buildings and estimated per-unit costs from $15,000 to $224,900. The low end is for buildings that are already partly sprinklered and have a fire service line and standpipe in place. The high end is for buildings with no fire-suppression infrastructure, where owners choose a fully concealed system. Permit and plan review fees alone came to about $9,939 for a 50-unit building.
Russian Hill's hills matter here. Supervisor Stephen Sherrill, who requested the report along with Supervisor Danny Sauter, told the Chronicle that some buildings "take a lot of work to get water pumped up to the top of a hill." Where a building sits on a slope and how far it is from a usable water main both affect its estimate, and those details don't show up on a listing.
Not everyone agrees on the numbers. The National Fire Sprinkler Association said costs would be closer to $10 a square foot and pointed to a 12-story Philadelphia building that came in at $12,700 per unit. Ahsha Safaí of the Building and Construction Trades Council said industry experts expect costs closer to $15,000 or $20,000 per unit. Since a single building could fall anywhere in that range, buyers need the estimate for the specific building they are considering.
Two Deadlines on the Same Date
Under the original schedule, permit applications were due January 1, 2027. The 2025 Fire Code amendments, passed by the Board on March 10, 2026, replaced that schedule with calendar deadlines. State reserve law now lines up with them.
- December 31, 2025. San Francisco's Department of Building Inspection says buildings of five stories or more built between 1926 and 1970 were due to file comprehensive facade inspection reports under the city's Facade Inspection and Maintenance Program. Buildings in that tier that are 15 stories or taller also owe a supplemental report by December 31, 2030.
- Mid-December 2026. The San Francisco Chronicle reports that the Fire Code Technical Advisory Council has to issue findings within 90 days of its first meeting. That meeting took place on September 18, and more than 100 condo owners attended.
- January 1, 2032. Covered buildings must submit sprinkler permit applications with professionally prepared drawings. On the same day, the reserve-funding requirements of California's AB 2050 take effect.
- January 1, 2034. The riser must be installed and connected to the water supply.
- January 1, 2035. The full system, including piping, sprinkler heads, and electrical monitoring, must be complete.
Governor Newsom signed AB 2050 on September 29, 2026, as Chapter 796 of the Statutes of 2026. Starting in 2032, an association has to fund its reserves each year at no less than the minimum level in its most recent reserve study. If reserves are projected to drop below zero at any point in the next 30 years, the association must put at least 15 percent of its gross annual budget into reserves until the shortfall is gone. If the budget can't cover that, the board has to levy a reserve-funding special assessment, and it can't do so more than once every nine years.
Owners in affected towers are already raising money. In November 2025, homeowners associations told the Chronicle they would need to start assessing owners more than $2,500 a month to save for the sprinkler work.
The Chronicle's coverage of AB 2050 noted that California HOAs can already raise regular dues by up to 20 percent a year, and levy special assessments totaling 5 percent of the expense budget, without a member vote. The same article cited a UC Berkeley Haas researcher. He found that after Florida required condo buildings to fund reserves in 2022, HOA fees rose and prices in those buildings fell. He added that California associations may be better prepared, because the state already requires a reserve review every three years.
Three Buildings at the Same Price
These two rules affect Russian Hill's building types in different ways. The rows below summarize what the sources say about each type. They are not a judgment about any particular address.
| Building profile | Sprinkler rule | AB 2050 reserves from 2032 | Where the cost range points |
|---|---|---|---|
| Pre-1970s tower without separated fire-rated stairs or compliant alarms, no existing suppression | Covered by the height test | Applies | Toward the high end of the $15,000 to $224,900 modeled range |
| Covered tower that is already partly sprinklered with a fire service line in place | Covered by the height test | Applies | Toward the low end of the modeled range |
| Smaller condo or co-op building below the 75-foot threshold | Not covered | Applies when the major-component threshold is met, whatever the unit count | Depends on the building's own reserve study |
The Analyst's report explains the middle row. One example is Fontana Towers, which the Chronicle places in the Marina. Resident Mark Kane, a retired San Francisco firefighter, described it as "a concrete fire-proof box" that already has more than 400 sprinkler heads in its below-grade area. The building is still covered by the rule, but its starting point is far from a tower that has no suppression infrastructure at all.
The last row covers most of Russian Hill's smaller buildings. AB 2050 doesn't exempt associations by unit count. It applies when the replacement value of the major components is at least half of the association's gross budget. Stock cooperatives are common interest developments under California law, so co-ops on the hill are included.
Where the Numbers Show Up in the Paperwork
None of this is hidden. State law requires the information to be in the documents a seller hands over, and a buyer who reads them early can compare buildings on future cost as well as price.
- The Civil Code §4525 package. A seller must provide the governing documents, the association's most recent annual budget report, a written statement of current regular and special assessments, and any assessment changes the board has approved that aren't yet due. If the buyer asks, the seller must also provide board minutes from the past 12 months.
- The board's statement on special assessments. Under §5300(b)(5), the annual budget report must say whether the board has decided on or expects special assessments, and if so, the estimated amount, start date, and duration.
- Percent funded. The §5565 reserve summary reports the share of needed reserves the association has actually set aside, along with the current reserve deficiency per unit.
- The 30-year question. The §5570 Assessment and Reserve Funding Disclosure Summary asks whether projected reserves will cover major components over the next 30 years. If they won't, it lists the additional assessments needed, with approximate amounts and dates.
- The insurance summary. The budget report has to list property, liability, and earthquake coverage, with the carrier, policy limits, and deductibles.
In a covered tower, the board minutes are often where the sprinkler work appears first, as contractor bids, engineering reviews, or votes on new assessments. Under California Civil Code §4530, once the association receives a written request, it has 10 days to provide these documents. That means they can be reviewed during a contingency period.
A Few Questions Buyers Ask
Is there an official list of covered buildings? The Fire Department's guidance doesn't publish an address list. A map hosted by Fire Safe SF and attributed to the San Francisco Building Trades Council includes 1750 Taylor Street. However, it is a third-party resource, so coverage should be confirmed building by building against the height criteria in the Fire Code.
Could the mandate change before 2032? Yes. It is current law, and it is under review. The amended code allows financial hardship and displacement of residents to be considered in undue hardship requests. The advisory council, chaired by Supervisor Sherrill, will advise on waivers, alternate methods, and extensions. Condo owners at the first meeting called for repeal. Building trades representatives and some fire officials support implementation.
Does AB 2050 change anything before 2032? The new reserve study and funding provisions take effect January 1, 2032. A building bought in 2026 or 2027 will be operating under them well within a typical period of ownership. This is a summary of public sources, not legal or financial advice for any specific transaction.
