New Residential Dwelling Building Permit
A building permit is required for construction of any new residential dwelling. Residential structures with shared common spaces (i.e. condos, apartments, high/mid-rises) are processed as commercial new structure or shell permits.
A separate permit is required for electrical and plumbing work. As of October 1, 2023, all new single-family detached houses and duplexes (and some townhomes) that include a garage, driveway, or carport, must have one electric vehicle (EV) supply equipment or one EV-ready parking space. See Maryland Public Safety Code Annotated Section 12-205. When electrical applications are submitted for wiring of new housing units, you must include the EV wiring as a part of the application or provide documentation that the new housing unit is exempt from the requirement.
If the homeowner is not the contractor, the contractor must have a valid Maryland Home Builders Registration number (MHBR).
