Summary
Davis adds a local sprinkler trigger to the state Fire Code: any building other than a Group R (residential) occupancy needs automatic sprinklers once it hits 5,000 square feet, 25 feet in height, or three stories, and changing a building's use forces the whole structure into compliance.
903.2.12.1 Sprinkler requirements based on area. Automatic fire sprinkler systems are required in every building, except for Group R occupancies, in which the total floor area of all floors is 5,000 square feet or more, or any building 25 feet or more in height from grade plane or any building which is three or more stories regardless of height. Notwithstanding other provisions of this Code, this rule shall be applied to alterations, repairs, additions, and changes of occupancy to existing buildings as follows: ... b. ... No change shall be made in the character of occupancy or use of any existing building or structure unless the entire building or structure is made to comply with this Chapter.

Full Breakdown
040 under Ordinance 2680 (effective January 1, 2026), requires an approved automatic fire sprinkler system in every building except Group R occupancies where the combined floor area of all floors reaches 5,000 square feet or more, where the building is 25 feet or more in height from the grade plane, or where it has three or more stories regardless of height. The rule reaches existing buildings, not just new construction: alterations or repairs that do not add floor area, height or stories can proceed without triggering full compliance, but the moment an owner changes the character of occupancy or use of an existing building, the entire structure must be brought up to the sprinkler chapter's standard.
The Chief Building Official and the fire chief can approve a change of occupancy without full sprinkler retrofitting only where the new use is no more hazardous, based on life and fire risk, than the use it replaces, and even then a Certificate of Occupancy is required before the changed use may operate. 01, which adopts the 2025 California Fire Code by reference and authorizes the fire chief's Division of Fire Prevention to administer and enforce it, including a Council-set fee schedule for plan review and inspections kept on file with the City Clerk and fire chief.
Violations & Fines
Fire Code violations in Davis are enforced by the Division of Fire Prevention under the fire chief. Because Chapter 13 incorporates the Fire Code's own enforcement and correction-notice procedures, a building found out of compliance can be ordered to install sprinklers or halt occupancy until it does, and a change of occupancy without the required Certificate of Occupancy exposes the owner to the code's general administrative citation and civil remedies under Article 1.02.
