Victorville, CA Building Safety: Fire Sprinkler Requirements (2026)

Section 16-5.04.020 of the Municipal Code adopts the 2025 California Residential Code (Title 24, Part 2.5), incorporating the 2024 International Residential Code with California amendments, as the City's residential code, with a copy on file in the Building Department for public inspection. Section 16-5.04.025 then designates a single enforcing authority for the sprinkler mandate that code carries: the Building Official also serves as the Fire Code Official when enforcing Section R313 Automatic Fire Sprinkler Systems of the California Residential Code. That dual role means a Victorville homeowner or builder submits sprinkler plan review and inspection requests to the same Building Department that handles the rest of the building permit, rather than a separate fire authority, for any one- or two-family dwelling or townhouse project that falls under R313.

The adopted Residential Code's climatic and geographic design table, set out at Section 16-5.04.040, also fixes Victorville-specific design criteria a sprinkler and fire-suppression contractor must build around, including a 12-inch frost line depth, 96 mph design wind speed, and 2,875-foot elevation for the City. Sprinkler systems installed under a Victorville permit are subject to the same twelve-month permit expiration under Section 16-5.01.110 and 180-day application expiration under Section 16-5.01.100 as any other building permit, since Article 4 operates under the Administrative Building Code's permit procedures in Article 1.
