Why carbon monoxide detector installation comes up in Annapolis
Maryland requires carbon monoxide alarms in homes with fossil-fuel appliances or attached garages, and many Annapolis homes heat with gas or oil. Rentals near the Naval Academy and downtown must have working alarms for tenants. Maryland requires battery-only smoke alarms to be sealed ten-year units, so combination smoke and CO alarms are a common upgrade.
Renovations under permit typically call for hardwired, interconnected units, which in historic homes means careful routing. Permits come from the City of Annapolis' planning and zoning permits office. Test alarms monthly and replace them by the printed date.
