Why carbon monoxide detector installation comes up in Washington
DC requires carbon monoxide alarms in homes with fuel-burning appliances or attached garages, and rowhouses with gas furnaces, boilers and water heaters in the basement need them near bedrooms and on each level. Landlords must provide working alarms in rental units, including basement apartments. Combination smoke and CO alarms simplify installation, and renovations under permit typically require hardwired, interconnected units.
Rowhouse plaster and party walls make wiring slower. DC Fire and EMS has offered alarm installation programs for residents. Permits come from the Department of Buildings. Test alarms monthly and replace them by their date.
