Summary
Glendale amends the adopted 2024 International Residential Code so alterations, repairs, and additions that would normally require added smoke alarms are excused for specific limited work, like pool installs or patio covers, under IRC § R310.2.2. Separately, Glendale's residential rental property code, § 29.1-16, sets its own smoke detector installation, placement, and six-month compliance deadline for rental housing.

Full Breakdown
2 of the adopted 2024 International Residential Code generally requires smoke alarms to be added when a home undergoes alterations, repairs, or additions. Glendale Code § 9-18 amends that section to add five more exceptions so the triggers for smoke-alarm upgrades don't apply to swimming pools, electrical panel replacements, covered patios and shade structures such as porches or decks, detached garages or other detached accessory structures (this exception does not cover accessory dwelling units), and photovoltaic solar systems. 1-16: detectors must be installed and maintained in good operating condition to the code edition in effect when the property was built or altered, and if none was required at that time, or none sits centrally located in the corridor or area serving each sleeping area, the owner had to install one within six months of the chapter's effective date.
Those detectors can be battery-powered or hard-wired into the building's electrical system, must be mounted on the ceiling or wall at a point central to the corridor or area giving access to each sleeping area, and must sound an alarm audible in every sleeping area of the rental unit. 1-16(b) fails the city's minimum residential rental property standards.
Violations & Fines
A residential rental property missing a required smoke detector under § 29.1-16(b) fails Glendale's minimum standards for residential rental property and can be cited as a hazard condition under Chapter 29.1's enforcement provisions. Alterations, repairs, or additions that trigger the smoke-alarm requirement under IRC § R310.2.2 but skip the required alarms, and don't fall within one of the listed exceptions, are a building code violation enforced by the Building Safety Division.
