Lubbock, TX Building Safety: Carbon Monoxide Detectors (2026)

1, Opening protection, to add a local carbon monoxide requirement on top of the model code's fire-separation rules. As amended, the section forbids any opening from a private garage directly into a room used for sleeping purposes. Other openings between the garage and the residence must use a solid wood door at least 1-3/8 inches thick, a solid or honeycomb-core steel door of the same minimum thickness, or a 20-minute fire-rated door. The city then adds its own sentence requiring a hard-wired carbon monoxide detector within five feet of the residence side of the garage door entrance to the structure, which is stricter than the base IRC's location-general carbon monoxide alarm rule.

003 supersede them, with the more specific city provision controlling any conflict. This carbon monoxide mandate is enforced at the building-permit and inspection stage for new construction and garage-to-house door alterations, since the building official reviews compliance with the adopted residential code as part of plan review and inspection before issuing a certificate of occupancy.
