Lafayette Parish, LA Building Safety: Carbon Monoxide Detectors (2026)

Under the LCG Property Maintenance Code, carbon monoxide alarms must be installed in dwellings per the International Fire Code (or the International Residential Code for covered dwellings), and both CO alarms and CO detection systems must be maintained per NFPA 720. Any alarm or detector that goes inoperable or starts giving end-of-life signals must be replaced. The rule applies in the City of Lafayette and in unincorporated Lafayette Parish alike -- Sec. 26-33 makes this chapter's requirements citywide and parish-wide unless a section says otherwise, and Sec. 26-285 carries no carve-out. Broussard, Carencro, Duson, Scott, Youngsville and Milton are separate municipalities with their own codes.
