Corona, CA Fire Regulations: Propane Storage (2026)

Storage and use of liquefied petroleum gas (propane) in unincorporated Riverside County is regulated by Chapter 61 of the California Fire Code, adopted via Ordinance 787, plus NFPA 58. Under CFC Table 6104.3, minimum separation distances for above-ground ASME containers depend on capacity: containers from 501 to 2,000 gallons water capacity must be at least 10 feet from buildings and from the lot line of adjoining property that can be built upon (and 25 feet between containers); containers from 251 to 500 gallons must be at least 10 feet from buildings/lot lines; and smaller containers under 125 gallons must generally be 10 feet from buildings. All parts of an underground LP-gas container must be at least 10 feet from a building or buildable lot line. Per CFC Section 6101.3, when a single container exceeds 2,000 gallons water capacity, or the aggregate exceeds 4,000 gallons, the installer must submit construction documents. Permits are required per CFC 6101.2 (referencing Sections 105.5/105.6). Portable cylinders in buildings are restricted (Section 6103.2.1), and cylinder storage is governed by Section 6109. Separately, for wildfire safety, California defensible-space guidance (PRC 4291, Zone 2) directs maintaining roughly 10 feet of clearance to bare mineral soil around propane tanks. Always confirm tank siting and permit needs with Riverside County Fire before installation.
