Only a licensed electrical contractor who is registered with Baltimore County can apply for an electrical permit.

An electrical permit is required for:

  • All electrical work, including the extension of circuit wiring
  • All types of electrical installations, including new installations and low voltage wiring, which are required to be installed by a contractor licensed in Baltimore County.
  • All types of wiring and equipment installations, including connecting replacement equipment to existing wiring.

An electrical permit is not required for:

  • Ordinary maintenance of existing electrical systems including light fixtures (such as lamps) and switches. 

Proper permits must be obtained prior to the commencement of any work. Working without a permit is a violation and subject to a civil penalty of $1,000. 

Existing electrical services are not required to be upgraded; however, mortgage companies may require a minimum 100-amp, 240-volt service with circuit breakers. Aluminum wiring is not required to be replaced.

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.
