MD General Assembly Changes CO Alarm Rules

244

The Maryland General Assembly has made some slight changes to the legislation passed last year about carbon monoxide alarms. The alarms are required above every room where someone sleeps and on every level including the basement of houses that have fuel burning equipment, wood burning appliance or an enclosed, attached garage. They are not required for houses that are powered solely by electric and have no attached garage. In rental units, the alarms need to be powered by hardwired electric with batter backup, a 10-year, sealed tamper resistant battery or a monitored fire alarm system. Hotels, dorms and rooming houses must make these changes by April 1. All other rental units must change by April 1, 2018.
