Colorado law requires working carbon monoxide alarms within 15 feet of every sleeping room in homes with fuel-fired appliances, fireplaces, or attached garages. Smoke alarm placement follows the state-adopted building and fire codes.
There is no separate Adams County smoke-alarm ordinance; the requirement comes from state law and the adopted building/fire codes. Colorado Revised Statutes require an operational carbon monoxide alarm within 15 feet of the entrance to each sleeping room in single-family dwellings that have a fuel-fired heater or appliance, a fireplace, or an attached garage—triggered on sale, transfer, tenant change, or permitted alteration. Smoke alarms are governed by the International Residential/Fire Code adopted countywide: typically one in each bedroom, outside each sleeping area, and on every level. Landlords must install and maintain both alarm types and provide fresh batteries at move-in.
Selling or renting a covered dwelling without required alarms violates state law; local building officials can withhold permits or certificates of occupancy until alarms are installed.
