Caldwell, ID Fire Regulations: Propane Storage (2026)

Caldwell City Code Article 13 adopts the International Fire Code as currently adopted by the Idaho State Fire Marshal under Title 41, Chapter 2 of the Idaho Code. The Idaho State Fire Marshal currently adopts the 2018 International Fire Code (via IDAPA rule), so the 2018 IFC Chapter 61, Liquefied Petroleum Gases, controls propane storage and use in Caldwell. Chapter 61 regulates where LP-gas containers may be placed relative to buildings and property lines, container quantities for buildings not open to the public, and protection of cylinders from damage and tampering. Common practical effects of these provisions include keeping portable cylinders away from building openings and basements, storing spare cylinders outdoors and upright, and observing separation distances from exposures spelled out in the chapter's tables. Larger fixed tanks and bulk plants are subject to additional Chapter 61 siting and NFPA 58 standards. Because propane handling here flows from the adopted fire code rather than a Caldwell-specific section, the Caldwell Fire Department / fire marshal is the authority that inspects and enforces LP-gas installations, and connections to appliances are also subject to the adopted plumbing and mechanical codes and permit requirements.
