Summary
San Leandro's short-term rental standards require that any dwelling unit hosting a permitted rental 'have a smoke detector, a fire extinguisher, a carbon monoxide detector, and adequate egress, all as required by current codes and regulations' (§ 4-40-130(d)). This is the local code's specific carbon monoxide mandate for permitted short-term rentals, layered on top of statewide detector requirements.

Full Breakdown
The requirement sits among the mandatory § 4-40-130 standards every hosted short-term rental permit must meet, alongside the 180-day cap and primary-residence rule. ' Section 4-40-130(e) separately requires the permittee to post, in a prominent place inside the unit, a diagram showing exits, fire extinguisher locations, Fire and Police Department phone numbers, the permittee's contact information, and the City's Noise Ordinance hours, so a guest can find both the safety equipment and emergency contacts at a glance. Because the standard is tied to the Chapter 4-40 permit rather than a freestanding citywide detector mandate, it is enforced the same way as the other rental standards: the Finance Director and Community Development Director must find the unit conforms before issuing or renewing a permit (§§ 4-40-160, 4-40-170(c)), and Code Enforcement or Police can issue a notice of violation for a missing detector, with permit suspension or revocation possible if it isn't fixed (§ 4-40-180).
Violations & Fines
A short-term rental found without a working carbon monoxide detector, smoke detector, or fire extinguisher fails the § 4-40-130(d) standard and is subject to a notice of violation from Code Enforcement or the Police Department. If the equipment isn't installed within the compliance window given, the Finance Director may suspend, revoke, or modify the rental permit on seven days' notice (§ 4-40-180).
