Test and service carbon monoxide alarms before each new tenancy. Colorado requires a working carbon monoxide alarm within 15 feet of each bedroom entrance in rentals with a fuel-fired heater or appliance, a fireplace, or an attached garage, and checking before each new tenant moves in lets you replace any missing or dead alarm and provide the batteries it needs, as the law requires at every turnover.
