Iron County, UT Building Safety: Carbon Monoxide Detectors (2026)

Iron County Code § 17.36.290(G)(1)(b) lists the basic public health and safety equipment every short-term rental in the unincorporated county must contain before it can be licensed and rented. Item (iii) requires an operable carbon monoxide detector on each floor, installed per the manufacturer's specifications, whenever gas appliances are utilized in the structure. That sits alongside the other mandatory items in the same subsection: one operable fire extinguisher (i); an operable smoke detector in each bedroom, in the major living areas, and on each floor, with one detector allowed to cover both a major living area and that floor (ii); a posted map showing property boundaries, parking spaces, emergency exits, and local emergency contact numbers (iv); and on-site parking (v).

Short-term rental is a permitted use in every zone that already permits a residence or residential facility under Section 17.16.030 (§ 17.36.290(G)(1)(a)), so the carbon monoxide requirement applies wherever a short-term rental can lawfully operate, not just in a subset of zoning districts. The operator must post a copy of the short-term rental business license inside the unit (§ 17.36.290(H)(8)) and provide renter notification of emergency information before occupancy (§ 17.36.290(H)(3)), which ties directly back to the safety equipment required under (G)(1)(b). The zoning administrator can modify a standard condition on a written hardship showing tied to physical site constraints under § 17.36.290(H)(9), but any modification cannot exacerbate an existing problem.
