Full Breakdown

Bryan adopts the 2021 International Residential Code as its controlling residential building code (Sec. 14-46), which includes Section R315 Carbon Monoxide Alarms. Sec. 14-47 then locally amends R315.2.2 (Alterations, Repairs, and Additions) by deleting exception #2: the exception that would otherwise excuse plumbing or mechanical permit work from triggering alarm installation. The result: any permitted alteration, repair, or addition to an existing dwelling, including mechanical or plumbing work, now requires carbon monoxide alarms to be installed per code.

Violations & Fines

Failing to install required CO alarms during permitted work can hold up inspections and final approval; the chief building official enforces IRC compliance, with general code violation penalties under Sec. 1-14 of the Bryan Code (see Sec. R113.4 as locally amended).
