California Building Code Title 24 requires automatic fire sprinklers in new one and two-family dwellings statewide. Fresno enforces these requirements through Fresno Fire Department plan review and Building and Safety inspections, with limited exemptions for additions and remodels.
California Residential Code Section R313, part of Title 24, mandates NFPA 13D-compliant automatic fire sprinkler systems in all newly constructed one and two-family dwellings and townhouses. Fresno enforces this through joint plan review by Fresno Fire Department and the Development and Resource Management Department building division. Substantial additions exceeding code thresholds may also trigger sprinkler retrofit, while minor remodels typically do not. Acceptance testing involves hydrostatic testing, flow tests, and contractor certification. Backflow prevention coordinates with Fresno Department of Public Utilities. Existing homes are not retroactively required to install sprinklers absent a major reconstruction triggering current code.
Stop-work orders issue for sprinkler omissions; penalties include doubled permit fees, occupancy denial, and required system retrofit before final inspection.
