Lassen County, CA Fire Regulations: Propane Storage (2026)

No Lassen County-specific propane ordinance was identified; propane storage is regulated by the statewide California Fire Code (Title 24, Part 9) and the California Mechanical and Plumbing Codes, which adopt NFPA 58 (Liquefied Petroleum Gas Code). These codes set minimum separation distances between LP-gas containers and buildings, property lines, and sources of ignition, with required clearances increasing as tank water capacity increases (small residential tanks have smaller setbacks than large bulk tanks). The codes also address tank anchoring, protection from vehicle impact, and clearance of combustible vegetation around tanks — particularly important in Lassen County's wildfire-prone State Responsibility Area, where keeping the area around a propane tank clear supports PRC 4291 defensible space. Installation of permanent propane tanks and associated gas piping typically requires a permit and inspection through the Lassen County Planning and Building Services Department, and bulk storage at commercial facilities is subject to California Fire Code permitting and CAL FIRE review. Suppliers filling and installing tanks must also comply with state and federal LP-gas safety rules. Because this is governed by adopted statewide codes rather than a unique county ordinance, exact clearances depend on tank size and configuration and should be confirmed with the county building department.
