Riverside, CA Fire Regulations: Propane Storage (2026)

Through RMC Ch. 16.32, the City of Riverside adopts California Fire Code Chapter 61 — 'Liquefied Petroleum Gases' — and NFPA 58 by reference. CFC §6101 requires that the storage, handling, transportation, and use of LP-gas, and the installation of LP-gas equipment, comply with Chapter 61 and NFPA 58. Key provisions: (1) LP-gas cylinders may not be stored in basements, pits, beneath stairways, or in similar locations where heavier-than-air vapors could accumulate (CFC §6109.10 / NFPA 58 6.19); (2) cylinders in storage must be secured upright with valves protected (CFC §6109); (3) on one- and two-family dwellings, no more than two 25-lb (or one 100-lb) cylinders are typically allowed near the structure without further separation; (4) under CFC Table 105.5.LPG (operational permit thresholds), an operational permit is required to store or use more than 125 gallons of LP-gas aggregate water capacity. Container setbacks from buildings, property lines, and ignition sources are dictated by Table 6104.3 (e.g., a 500-gallon ASME tank must be at least 10 feet from a building and property line).
