Solano County, CA Building Safety: Carbon Monoxide Detectors (2026)

30(A)(7)(e) sits inside the fire-safety subsection of Solano County's vacation house rental ordinance, immediately after the rules gating High and Very High Fire Hazard Severity Zone approvals. It applies to every permitted vacation house rental in the county, not only those in a mapped fire hazard zone: the dwelling and each bedroom must be equipped with functional smoke and carbon monoxide alarms, and at least one functional fire extinguisher must be available and readily marked. The requirement is bedroom-by-bedroom, so a rental with a guest house counted toward occupancy under subsection (A)(2) must alarm each bedroom in the guest house as well as the main dwelling, matching the per-bedroom occupancy cap in subsection (A)(3) of up to two guests per bedroom.

The fire extinguisher requirement is a minimum of one per property, but it must be functional and marked so guests can find and use it, and Resource Management can verify both the alarms and the extinguisher during the periodic permit renewal required every five years under subsection (A)(14). This alarm and extinguisher mandate operates alongside the separate fire-pit restriction in subsection (7)(d), which bars guests from using any fire pit, fireplace, or other outdoor fire feature on a vacation house rental property, and the operator's duty under subsection (7)(f) to inform guests of area fire risk and evacuation routes.

All of subsection 7 traces back to the same permit condition: an operator who fails to maintain working alarms is out of compliance with the vacation house rental land use permit itself.
