Full Breakdown
296, folds carbon monoxide detection into both the permit application and the ongoing host duties for home-sharing and hosted-stay units. ii requires the host to sign a notarized affidavit confirming that the space used for short-term rental meets or exceeds fire and life safety requirements, expressly including installation of smoke and carbon monoxide detectors and adequate means of egress; this affidavit is a condition of eligibility for the permit issued by the Planning and Community Development Department. 4, under the chapter's host requirements, obligates the host to provide and maintain fire extinguishers, smoke detectors, and carbon monoxide detectors, together with information about emergency exit routes and emergency contact information, for guests.
I that can suspend or revoke the rental permit. Because the code ties detector maintenance to the host's ongoing eligibility rather than treating it as a one-time inspection item, a missing or non-functioning carbon monoxide detector discovered during a complaint-driven inspection can itself count as a violation under the section's general compliance clause.
Violations & Fines
Failing to provide or maintain a carbon monoxide detector is a violation of Section 17.50.296 and can be counted toward the three-violation threshold in subsection I.3 that triggers automatic permit suspension, followed by a possible revocation hearing before the city manager under Chapter 1.25.
