Fire sprinkler requirements differ by structure type: commerical structures, residential structures other than one and two family dwellings, and residential dwellings. All systems can be designed to meet higher standards. Systems are typically designed and installed by a C-16 licensed fire protection contractor. All copies of the plans shall be wet-stamped and signed by the licensed designer.

401D Residential Fire Sprinkler System Standard

• Commercial structures need to comply with NFPA 13.
• Residential structures other than one and two family dwellings need to comply with NFPA 13R and local standards.
• Residential dwellings need to comply with NFPA 13D and RVFD Standard 401D. 
• Fire Sprinkler Systems require two inspections: a hydro/rough and a final. Both inspection fees are included in the initial sprinkler system submission fee.
• Re-inspections or failures to comply will result in an additional inspection fee of $110 per visit.
