Chino Hills, CA Fire Regulations: Propane Storage (2026)

Chino Hills does not have a unique propane ordinance; liquefied petroleum gas (LP-gas) storage is regulated by the California Fire Code Chapter 61, which the Chino Valley Independent Fire District enforces locally. The Fire Code allows LP-gas containers of less than 125-gallon water capacity to be placed next to the building they serve when the installation complies with specified safety provisions — this covers typical residential uses like barbecue cylinders, patio heaters, and small house tanks. When several smaller containers are grouped so that the aggregate water capacity reaches 500 gallons or more, the minimum separation distances must comply with the appropriate portion of Fire Code Table 6104.3 using the aggregate capacity. The Code sets an overall limit for protection of heavily populated or congested areas: the aggregate capacity of any one installation generally must not exceed a water capacity of 2,000 gallons. Permitting thresholds escalate with size — where a single LP-gas container exceeds 2,000 gallons water capacity, or the aggregate water capacity of containers exceeds 4,000 gallons, the installer must submit construction documents for the installation. For ordinary homeowners, the practical rules are: use approved cylinders, keep them outdoors and away from ignition sources and building openings, do not store spare full cylinders indoors or in occupied spaces, and obtain Fire District approval for larger fixed tanks. Because parts of Chino Hills lie in Very High Fire Hazard Severity Zones, tank placement and clearance from vegetation are especially important in hillside areas.
