Carbon Monoxide Detector Requirements for Maryland (MD) Landlords
In April 2018, Maryland legislation went into effect requiring rental units to have carbon monoxide alarms installed on every level of the unit, including the basement.
The law applies to dwellings that contain one or more of the following:
fuel-burning equipment
an attached garage
wood-burning
fireplaces
pellet stoves
The Carbon Monoxide (CO) alarms must be installed in one of the following ways:
Hardwired into an alternating current power line with secondary battery backup
Battery-powered, sealed, tamper-resistant and using a battery with a life of at least 10 years
Through a security system (i.e. connected to an on-site control unit that monitors the carbon monoxide (CO) alarm remotely and alerts a responsible party when the device sounds an alarm
Combined with a hard-wired smoke alarm, if the combined device complies with Underwriters Laboratories (UL) and American National Standards Institute (ANSI) standards.
The law also requires owners to provide written information on alarm testing and maintenance to at least one adult occupant of the unit, to maintain records of notification, and to install alarms for hearing-impaired residents if a hearing-impaired person lives in the unit.
