Summary

In Cathedral City, California, the city issues no initial or renewal short-term vacation rental permit for a property that lacks functioning smoke and carbon monoxide detectors. This is a condition of the STVR and home share permit under Chapter 5.96, enforced through the city's health and safety inspection before each permit is issued.

L. No initial or renewal permit shall be issued if the property to be used for short-term vacation rentals does not have functioning smoke and carbon monoxide detectors, HVAC, electricity or plumbing, the structure has been substantially modified in any way that required a building permit from the city and a permit was not obtained, or the city determines that any other conditions are present on the property that would present a substantial threat to the health, safety or welfare of guests.

Full Breakdown

Section 5.96.040(L) of the Cathedral City Municipal Code, part of the short-term vacation rental chapter enacted by Ordinance 842 (2020) and amended by Ordinance 859 (2022), states that no initial or renewal permit shall be issued if the property does not have functioning smoke and carbon monoxide detectors. The same sentence lists three more bars to a permit: no HVAC, electricity or plumbing; a structure substantially modified in a way that required a building permit from the city when no permit was obtained; and any other condition the city determines presents a substantial threat to the health, safety or welfare of guests. The section requires the detectors to be functioning but does not print a count or placement rule for them.

The detector check happens at the inspection. Under § 5.96.040(K) the permit application comes with a consent to inspection signed by the owner, and the city conducts a health and safety inspection of the unit before issuing a new permit and before issuing any renewal permit. That inspection also verifies the number of bedrooms originally permitted and authorized under the original certificate of occupancy and confirms that no space has been converted into a bedroom or living space without all required permits. If the unit has a privately owned pool or spa, § 5.96.040(M) has the city inspector confirm it was built under a valid city permit and operates safely.

Because home sharing is a form of short-term vacation rental, and the chapter applies its STVR provisions to home shares unless expressly provided otherwise, the detector condition covers home share permits as well. The rule in § 5.96.040(L) is a permit condition in Cathedral City for rentals to guests. Since permits renew annually, the detectors must be in working order at every renewal. An owner whose new permit application is denied under § 5.96.040(N) can apply again only after twelve months from the date of denial (§ 5.96.040(O)).

Violations & Fines

A property without functioning smoke and carbon monoxide detectors gets no initial or renewal STVR permit under § 5.96.040(L). Renting without a valid permit draws fines and penalties, administrative citations under Chapter 13.58 with each day a separate violation, and possible misdemeanor charges under § 5.96.070. A third citation within twelve months suspends the permit for up to six months.

Frequently Asked Questions

Does Cathedral City require carbon monoxide detectors in every home?
The provision found in the Cathedral City code is a condition on short-term vacation rental permits. Section 5.96.040(L) bars any initial or renewal STVR permit for a property without functioning smoke and carbon monoxide detectors. It sets no count or placement rule for them.
When does the city check the detectors?
At the health and safety inspection. Section 5.96.040(K) requires the owner to consent to inspection with the application, and the city inspects the unit before issuing a new permit and before issuing any renewal permit. The same inspection verifies bedroom counts against the original certificate of occupancy.
What else can block a vacation rental permit under the same section?
Section 5.96.040(L) also bars a permit when the property lacks HVAC, electricity or plumbing, when the structure was substantially modified in a way that required a city building permit and none was obtained, or when the city finds any other condition that presents a substantial threat to guests' health, safety or welfare.
Does the detector rule apply to a home share in Cathedral City?
Yes. Section 5.96.020 says that, unless the chapter expressly provides otherwise, all provisions that apply to short-term vacation rentals apply to home sharing. Section 5.96.040(L) has no home share exception, so a home share permit also requires functioning smoke and carbon monoxide detectors.
