Grand Junction, CO Building Safety: Carbon Monoxide Detectors (2026)

GJMC 21.04.030(d)(5)(vi)(B) lists a carbon monoxide detector in good working order as a required item the owner must demonstrate and certify is present on the premises at all times for any short-term rental. It sits directly alongside the smoke detector requirement and a requirement for adequate, functional building egress from each sleeping room, forming a three-part life-safety checklist tied to the permit rather than a stand-alone inspection. The owner must also give the City or its agent access to inspect the premises both while the permit application is pending and afterward on reasonable notice, which is how Community Development confirms the detector is actually installed and working rather than relying on the owner's certification alone.

The posted-notice requirement in the same subsection separately requires the owner to display building-exit and fire-extinguisher locations, a 24-hour emergency contact, and other safety information in a highly visible spot, so a guest staying in a Grand Junction short-term rental has both the physical detector and posted emergency information available at the same time.
