Full Breakdown

' Unlike many neighboring sections in the same chapter, which adopt the California Fire Code 'with the following exceptions, modifications, and additions', Section 915 carries no local carve-outs, so the state's carbon monoxide detection requirements apply to City of Los Angeles buildings exactly as written, with no LA-specific loosening or tightening. 916 (gas detection systems) in the same Chapter 9 fire-protection-systems grouping, all similarly adopted by wholesale reference rather than rewritten as local text. 1 to make rules for preventing fire and explosion hazards. ' Each day a violation continues is charged as 'a separate offense,' so an unresolved CO-detector deficiency can compound daily penalties.

Property owners and managers should treat CO-detector compliance as a Fire Code inspection item, since LAFD, not the Housing Department, holds enforcement authority for this section.

Violations & Fines

Any failure to comply with LAMC § 57.915's carbon monoxide detection requirement is prosecuted under the Fire Code's general violation clause, § 57.110.4: a misdemeanor punishable by up to $1,000 in fines, up to six months in jail, or both, with mandatory minimums set in Table 57.110.4. Each day the violation continues counts as a separate offense, letting LAFD stack daily penalties until detectors are installed and functioning.

Frequently Asked Questions

Does Los Angeles have its own carbon monoxide detector rule, or does it just follow the state?
Los Angeles doesn't rewrite the standard. LAMC § 57.915 simply states that 'Section 915 of the CFC is hereby adopted in its entirety,' so the California Fire Code's carbon monoxide detection requirements apply citywide exactly as the state wrote them, with no additional local exceptions layered on top the way some neighboring Fire Code sections carry.
Who enforces the carbon monoxide detector requirement in Los Angeles?
The Los Angeles Fire Department enforces § 57.915 as part of Article 7, the city's Fire Code. The Fire Chief and Bureau of Fire Prevention hold inspection and rulemaking authority under the same chapter, and violations are charged under the Fire Code's general misdemeanor penalty clause rather than through a separate housing inspection process.
What happens if a building doesn't have working carbon monoxide detectors?
Under § 57.110.4, failing to comply with any Fire Code requirement, including § 57.915, is a misdemeanor punishable by a fine of up to $1,000, imprisonment of up to six months, or both, with mandatory minimum fines set by Table 57.110.4. Each day the violation continues is treated as a separate offense.
