Low-voltage licensing
Maryland
Maryland requires state-level Electrical Contractor licensing through the Maryland State Board of Master Electricians. Additionally, alarm and electronic security work falls under the Maryland Security Systems Technicians Licensing Board, which is a separate licensing scheme.

Common pitfalls
Mistakes we see installers make when navigating Maryland licensing.
- Maryland licenses TWO boards depending on scope: Master Electricians for general electrical/low-voltage; Security Systems Technicians for alarm and electronic security. Doing both means holding both licenses.
- Counties (notably Montgomery, Prince George's, Anne Arundel) have their own contractor registration layered on the state license.
- Biennial renewal with CE requirements on both boards.
