Flagstaff, AZ Fire Regulations: Smoke Detectors (2026)

Flagstaff City Code § 3-12-001-0013(A) requires that each short-term rental be equipped with properly functioning smoke alarms that include battery backup and are installed in accordance with manufacturer specifications, and lists exactly where: on the ceiling or wall outside each separate sleeping area, in the immediate vicinity of bedrooms; within each room used for sleeping purposes; and on every story of the dwelling unit, including basements, though crawl spaces and uninhabitable attics are excluded. The same subsection requires the alarms to be tested regularly and kept in operable condition at all times, not just at initial licensing.

The smoke alarm mandate sits alongside the rest of § 3-12-001-0013's public-safety package for licensed STRs: carbon monoxide detectors wherever the unit has a fuel-burning appliance, fireplace, or attached garage; at least one fire extinguisher rated 2-A:10-B:C, inspected and tagged annually or after each use; and at least two unobstructed means of egress kept clear of furniture, storage, debris, snow, and ice. Because these requirements were enacted together under Ordinance 2026-11 on May 19, 2026, as part of the STR licensing chapter, a failure to maintain working smoke alarms is treated as a chapter violation subject to the STR enforcement scheme rather than a separate building-code citation. City Code Compliance, the Police Department, and the City Attorney share enforcement authority under § 3-12-001-0016, and a verified violation triggers the escalating civil penalties of § 3-12-001-0015.
