Yes — Maryland requires an electrical permit for Level 2 EV charger installation in most counties. Here's what the process looks like and why it matters.
Short Answer: Yes, You Need a Permit
In virtually every Maryland county, a Level 2 EV charger installation requires an electrical permit. This applies in Howard County, Montgomery County, Anne Arundel County, Prince George's County, Baltimore City, Frederick County, and most other jurisdictions. The permit is required because you're adding a new 240V dedicated circuit — a significant electrical modification that must be inspected for code compliance.
What the Permit Process Looks Like
A licensed electrician applies for the permit before starting work. Most Maryland counties process residential electrical permits in 1–3 business days. Some counties allow online permit applications with same-day approval for straightforward residential work. After installation, the county sends an inspector to verify the work meets National Electrical Code (NEC) standards. The whole process adds a few days to the project timeline but costs little — typically $75–$150.
Why You Shouldn't Skip the Permit
Unpermitted electrical work creates three real risks: it voids your homeowner's insurance if a fire originates from the unpermitted circuit, it creates problems when you sell your home (unpermitted work must be disclosed or remediated), and an improperly installed 240V circuit is a genuine fire and safety hazard. The permit process exists for good reasons.
