Santee, CA Building Safety: Carbon Monoxide Detectors (2026)

Santee does not impose a freestanding, citywide carbon monoxide detector mandate on every home; the requirement lives inside the condominium conversion chapter of the subdivision ordinance. Section 12.08.020(A) applies whenever an existing residential development is converted to a condominium, community apartment or stock cooperative, and requires a tentative map for five or more units or a tentative parcel map for four or fewer units, filed with the Planning and Building Department along with a physical inventory report from a licensed engineer, architect or contractor.

Subsection (C)(2) lists the building and fire code upgrades the Director of Planning and Building must condition that map on, unless the City Council waives or modifies them under subsection (F). Alongside upgrades to plumbing, guardrails and stairways, subsection (k) requires that smoke detectors and carbon monoxide detectors be installed in accordance with the California Building Code as one of those mandatory conditions. The same list also requires copper repiping in place of polybutylene plumbing, ultra-low-flow toilets and shower heads, and individual electric or gas meters for each unit, folding the detector mandate into a broader life-safety and utility upgrade package that only the ownership conversion itself triggers.

Subsection (F) allows a waiver only where the City Council finds the modification will not compromise health, safety or welfare, is justified by special or unusual circumstances of the specific building, and does not compromise the project's quality, so the detector requirement cannot be waived as a matter of routine.
