Billings, MT Fire Regulations: Smoke Detectors (2026)

Billings folds fire-safety equipment into its short-term rental rules rather than leaving it to the building code alone. Under Sec. 27-1005(O)(10)(a) of the zoning code, every licensed guest home or tourist home must contain smoke detectors, fire extinguishers, and CO2 detectors, and the unit must otherwise comply with the city's zoning, building, fire, and noise codes. The zoning coordinator checks this when issuing or renewing the annual short-term rental permit, and unresolved violations under Sec. 27-1621 can support denial or revocation. A general, stand-alone smoke-alarm mandate for other structures is not spelled out in this code: it runs through the adopted building and fire codes instead.
