When does SFFD Fire Prevention review apply?
Answered by AskBaily Editorial · Updated
Short answer
SFFD Bureau of Fire Prevention reviews high-rise buildings (75+ feet), R-1 occupancy (hotels, SROs), R-2 apartment buildings, mixed-use buildings with residential over commercial, and any project involving fire alarm, sprinkler, or standpipe systems. Residential remodels in small single-family homes typically only trigger SFFD review if you add an accessory dwelling unit or touch sprinkler plumbing.
In detail
The San Francisco Fire Department Bureau of Fire Prevention conducts plan review and field inspection on a defined slate of occupancy types and system installations under SF Fire Code (Title 23 of the SF Municipal Code), the locally amended 2022 California Fire Code. The trigger list is set by occupancy classification rather than project size, so a small project in a regulated occupancy can require full Bureau review while a large remodel in an unregulated occupancy can sail through.
Mandatory Bureau review applies to: high-rise buildings 75 feet or taller measured to the highest occupied floor (CFC Chapter 4 high-rise provisions); R-1 occupancies (hotels, motels, SROs, transient residential); R-2 occupancies (apartment buildings of three or more units); mixed-use buildings with residential above commercial (the dominant SF building typology in NC and RC zoning); buildings with fire-alarm systems under CFC Section 907; sprinkler installations or alterations under CFC Section 903 and NFPA 13/13R; standpipe systems under CFC Section 905; and any project triggering high-pile combustible storage, hazardous materials, or assembly use over 50 occupants.
For a single-family residence (R-3 occupancy) doing a kitchen, bath, or interior remodel that does not touch sprinkler plumbing, Bureau review typically does not apply — the work is reviewed by SF Department of Building Inspection under the building, mechanical, plumbing, and electrical disciplines and a separate fire submittal is not required. Two common SF residential projects do pull SFFD in: adding an Accessory Dwelling Unit under Planning Code Section 207, because the unit count change can flip the building from R-3 to R-2 if it is the third unit on the parcel; and any work touching the fire-sprinkler system in a building that has one, even on an R-3 single-family home in the Diamond Heights or Sunset retrofit zones. Plan review timelines run 3-8 weeks at the Bureau, with field inspection scheduled separately during construction.
