Verify smoke and carbon monoxide detectors before each new tenancy. Montana landlords must install an approved smoke detector in every rental unit and a carbon monoxide detector outside each sleeping area in any unit with fuel-fired appliances or an attached garage, then verify every detector works at the start of each rental agreement, and an annual check catches missing or disabled detectors before the next turnover.
