The county's rule
From Permits, Approvals and Inspections' electrical permit page (read 24 October 2026):
| What the county says | What it means for you |
|---|---|
| A permit is required for "All electrical work, including the extension of circuit wiring" | A new outlet, circuit, fixture location or panel is permit work |
| New installations, low-voltage wiring, and equipment installed or swapped onto existing wiring also need one | A doorbell or alarm system, a new appliance circuit and an EV charger are included |
| "Ordinary maintenance of existing electrical systems" does not | A like-for-like repair of an existing device |
| "Only a licensed electrical contractor who is registered with Baltimore County can apply for an electrical permit." | No homeowner permit |
| Work without a permit is a violation with a civil penalty of $1,000 | Plus the permit and inspection anyway |
New single-family houses and duplexes (and some townhomes) with a garage, driveway or carport must include EV charger wiring in the application, or show the house is exempt, citing Maryland Public Safety Article 12-205. The county applies to every community in it, from Towson to Dundalk; Baltimore City has its own office.
How to apply and get it inspected
- Your registered electrical contractor applies online through PAI; the county says to complete the steps "in the specified order". The fee table is linked from the same page; we could not read the amounts, so ask the contractor for the permit fee on the quote.
- Inspections are scheduled, rescheduled or cancelled through PAI's Electrical Inspections page. The county asks owners and contractors to coordinate requests. For a BGE "work/with" service installation, the contractor schedules a service inspection online, then calls the inspector beforehand.
- Questions: 410-887-3960, electinsp@baltimorecountymd.gov, 111 West Chesapeake Avenue, Room G-24, Towson, Monday to Friday 7:30 a.m. to 3:30 p.m.

The July peak is consistent with the county filing heat pumps and central AC as electrical permits. 21220 (Middle River) leads, ahead of 21117 (Owings Mills) and 21228 (Catonsville). Three in ten electrical permits from the first year were not yet marked complete; if yours is one, ask the electrician whether the final inspection was called for. Monthly counts are on Baltimore County electrical permits, every kind of work on Baltimore County permit statistics, and the rows on browse Baltimore County permits.
Before you hire
Look up the permits on your address on the county's Permit Search map, Electrical layer, as the Baltimore County building permit search guide shows. Rules elsewhere are in do I need a permit for electrical work, an electrical panel upgrade and an EV charger; filed costs elsewhere in electrical work cost.
What this does not tell you
The county's files name no contractor and carry no job value on trade permits, so we cannot rank electricians or give costs, and there is no final inspection date, so we show no time to final. Solar jobs count under solar for the building permit and here for the matching electrical permit.
