Summary
Hawthorne requires every short-term rental applicant to file a notarized affidavit swearing the unit has carbon monoxide detectors installed and meets or exceeds the city's fire and building-safety standards. Hawthorne Municipal Code § 17.74.020(A)(6) makes this affidavit, alongside adequate means of egress, a mandatory condition of getting a short-term rental permit.
A notarized affidavit attesting that the short-term rental meets or exceeds fire and building safety requirements, including, but not limited to, installation of smoke and carbon monoxide detectors, and adequate means of egress, and that the unit complies with all requirements of the Hawthorne Municipal Code.
Full Breakdown
' The affidavit is sworn under penalty of perjury because it is notarized, so a host who signs it without actually installing a CO detector is certifying a false statement. 060(E) lets the city inspect the unit 'at all reasonable times' with 24 hours' notice, giving code enforcement a way to verify the detector is actually in place after the affidavit is filed. 020(F)), a missing or falsely attested CO detector can hold up or void permit issuance.
Violations & Fines
A false or unsupported fire/building-safety affidavit is a misrepresentation that can trigger permit revocation under § 17.74.100(A)(1)-(2) after notice and a hearing before the city manager or designee. Operating a short-term rental without meeting the required carbon monoxide detector standards also exposes the host to the chapter's general enforcement remedies under § 17.74.090: a misdemeanor fine up to $1,000, up to six months in jail, or an administrative citation.
