Harford County, MD Building Safety: Electrical Permits (2026)

Section 105-2 adopts the National Electrical Code, 2023 Edition, including all annexes as adopted by the National Fire Protection Association, as the Harford County Electrical Code, incorporated by reference with the same force and effect as if printed in full, subject to local exceptions and modifications in the same section. All electrical installations in the county must meet that adopted code plus the chapter's own rules and regulations, and a copy is kept on file in the office of the Director of Administration. Section 105-1 sets the scope broadly: it reaches all electrical equipment and its installation for light, heat or power in or on public or private buildings, structures, yards, carnivals and parking lots, and industrial substations, but exempts ships, railway cars, automobiles and United States government installations.

Section 105-12 is the operative permit trigger: a person may do electrical installation, repair or maintenance work without the chapter's registration only if that person first applies to the Director for a permit where the chapter requires one, and the Director issues a permit only after finding the applicant qualified to perform the work without endangering life or property. No permit is required for minor repairs. A narrow owner-occupant exemption applies to an existing single-family home that is the owner's principal residence per Maryland Department of Assessments and Taxation records, or a new single-family home the owner will occupy as verified by affidavit; that exemption cannot be used for property held by any entity other than an individual, and it can be granted only once every 5 years from the date it was last used.

Registration itself sorts applicants into four classes under § 105-13: master, limited, restricted and limited journeyperson electrician, each requiring a current state license or, for restricted and limited masters, general liability insurance of $300,000 and property damage insurance of $100,000, plus a nonrefundable fee under § 157-24.
