Full Breakdown
Section 704.8 places the annual inspection duty squarely on the property owner or agent: smoke alarms that draw primary power from the building wiring must be checked for good operating condition once each year, and if they have battery backup, the battery must be replaced as necessary to keep the alarm working. Battery-powered smoke alarms must be tested annually for proper function, with batteries replaced as needed. Section 704.9 extends this to residential rental units governed by Chapter 10-3, Rental Licenses, B.R.C. 1981, requiring smoke alarms to be installed and inspected as detailed in Section 704.8 for those R-occupancies. Section 704.10 separately requires fire alarms in existing residential structures to be installed in accordance with Chapter 10-8, Section 907, the Fire Code, so a multi-unit rental building may need both individual smoke alarms under Chapter 10-2 and a building fire alarm system under Chapter 10-8 depending on occupancy type.
Violations & Fines
A failure to inspect or maintain a smoke alarm under Section 704.8 or 704.9 is a Property Maintenance Code violation subject to Section 107.1(b)'s escalating civil penalty schedule: $150 for a first violation, $300 for a second, and $1,000 for a third, and for a rental unit the city manager may also revoke the property's rental license. Criminal penalties under Section 5-2-4, B.R.C. 1981, remain available as an alternative remedy.
