Howard County, MD Parking Rules: EV Charging (2026)

105 of the Howard County Code, adopted by County Council bill in 2018 and amended in 2019, applies to new construction of Residential Group R-1 and R-2 occupancies, condominium or cooperative buildings with more than two units, and R-3 townhouse and single-family detached homes regardless of ownership. For a residential unit built with a garage, carport, or driveway, the developer must run a dedicated electric line of sufficient voltage so a charging station can be added later, even if no charger is installed at the time of construction.

For units without their own garage, carport or driveway, communal parking has its own threshold: developers must equip at least one shared parking space with a working EV charging station for every 25 residential units that lack individual charging infrastructure, and if that math produces an odd number or a fraction, the county rounds up to the next even number of required spaces. 207(c)(5) of the County Code. The Building Official can specify additional performance standards for the charging equipment itself. The section includes a sunset clause: it stops applying automatically if the Howard County Building Code is later updated with its own provisions requiring and regulating EV charging equipment for the same residential occupancies.
