Iron County, UT Fire Regulations: Smoke Detectors (2026)

Iron County Code § 17.36.290(G)(1)(b)(ii) sets the smoke detector standard for every short-term rental in the unincorporated county: an operable smoke detector is required in each bedroom, in the major living areas, and on each floor, with the code allowing the detector covering a major living area to also satisfy the requirement for that floor. The rule is one of the basic public health and safety conditions listed in § 17.36.290(G)(1)(b), adopted by Ordinance No. 2019-1 on March 25, 2019, alongside a required fire extinguisher (i), a carbon monoxide detector on each floor when gas appliances are used (iii), a posted emergency and parking map (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 smoke detector rule applies wherever a rental can lawfully operate. The operator must post a copy of the county-issued short-term rental business license inside the unit (§ 17.36.290(H)(8)), and the county's application process requires the operator to acknowledge in writing that the standards in § 17.36.290, including the smoke detector rule, have been read before a license issues (§ 17.36.290(F)(1)(g)). If the zoning administrator finds a site-specific hardship, standard conditions including the equipment list can be modified in writing under § 17.36.290(H)(9), though any change cannot make an existing safety problem worse.
