Maryland requires working, interconnected smoke detectors on every level of a home, including outside each sleeping area. Interconnected means that when one detector triggers, every detector in the home sounds — not just the one nearest the smoke. Battery-only detectors that aren't interconnected typically don't meet this standard, especially in homes that have been sold, renovated, or had a room added since the requirement took effect.
We install hardwired, interconnected smoke and carbon monoxide detectors, correctly placed and wired to meet current code — not just battery units stuck to a ceiling. Combination smoke/CO units are also available where a single detector covering both makes sense for the room.
Yes. Maryland law requires interconnected smoke detectors so that if one unit detects smoke, all units in the home sound, not just the nearest one.
Hardwired, interconnected smoke or CO detector installation typically costs $75 to $150 per detector, depending on wiring access and how many units are being added.
If your home has any fuel-burning appliance — a gas furnace, water heater, stove, or fireplace — a CO detector is strongly recommended and often required by code near sleeping areas.
Missing or non-interconnected smoke detectors are a common item flagged during home inspections and can complicate a sale. Updating coverage ahead of a listing is a common reason homeowners call.
