Summary
Victoria enforces smoke alarm installation through its adopted 2021 International Residential Code, and separately amends the electrical code to set the wiring standard for hardwired, interconnected smoke and carbon monoxide detectors in homes.
Section E3406.3 Minimum size of conductors is amended to read: The minimum size of conductors for feeders and branch circuits shall be No. 12 copper and No. 6 aluminum... Exception 1: Smoke/Carbon Monoxide detectors, where required to be hard wired, may use #14 copper conductors per Table 3702.14. Up to 12 devices may be interconnected per manufacturer instructions/NFPA 72 guidelines.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 42).
Full Breakdown
The City of Victoria has adopted the 2021 International Residential Code, which governs smoke alarm installation in one- and two-family homes and was not deleted or amended locally, so the model code's requirements stand as adopted. Victoria's own electrical code amendment, Section E3406.3 as amended by City Code § 21-63, confirms hardwired smoke and carbon monoxide detectors are required in new and renovated homes: it permits #14 AWG copper wire for hardwired detector circuits and allows up to 12 devices to be interconnected per manufacturer instructions and NFPA 72. Enforcement runs through the city's Development Services Department at permitting and inspection.
Violations & Fines
Building without code-compliant hardwired, interconnected smoke and CO alarms fails inspection and blocks certificate of occupancy; the permit holder must correct wiring before final sign-off from Development Services.
