Maryland Detector Law & DMV Rentals
Maryland has some of the more specific rental detector rules in the region — including the phase-out of older removable-battery smoke alarms in favor of 10-year sealed-battery units in many situations, and CO detector requirements for units with fuel-burning appliances or attached garages. Getting this wrong isn't just a failed inspection; it's real liability if there's ever a fire or CO event.
For landlords across Montgomery County, a turn is the clean moment to bring detectors current and document it. We place them correctly, install compliant units, test each one, and hand you dated records — so you're covered with the county and with your tenant from day one of the lease.
