How to Find a Licensed EV Charger Installer in Maryland (And Red Flags to Avoid)
Not every electrician is equally qualified for EV charger work. Here's how to find a licensed Maryland installer and the red flags that signal trouble.
Why Licensing Matters More Than You Think
EV charger installation involves 240V dedicated circuits, load calculations, and NEC code compliance. An improperly installed circuit — wrong wire gauge, improper breaker sizing, no GFCI protection where required — is a fire hazard and will fail inspection. In Maryland, electrical work must be performed by a licensed electrician or under the direct supervision of one. Hiring an unlicensed contractor voids your homeowner's insurance for any related claims.
What Credentials to Look For
Ask for: a Maryland Master Electrician or Journeyman Electrician license (verify at the Maryland Department of Labor's license lookup), a current Maryland Home Improvement Contractor (MHIC) license for residential work, general liability insurance of at least $1 million, and workers' compensation coverage. Any legitimate electrical contractor will provide all of these without hesitation.
Questions to Ask Before Hiring
How many EV charger installations have you completed in the past year? Do you pull the permit, or do you expect me to? Is permit and inspection included in your quote? What happens if the inspector requires corrections? Do you help with MEA rebate documentation? A contractor who hesitates on any of these questions — especially permit questions — is a red flag.
Red Flags
Be cautious of: quotes that are 50%+ cheaper than others (often means unlicensed or no permit), contractors who say permits 'aren't necessary for this type of work' (they are, in every Maryland county), handshake quotes with no written estimate, requests for full payment upfront, and contractors who can't provide a physical business address.
Getting Multiple Quotes
Get 2–3 quotes for any EV charger installation. For a standard residential job, quotes should be in a similar range — significant outliers in either direction deserve scrutiny. Make sure each quote is itemized: equipment, labor, permit, and inspection should all be listed separately. This makes comparison easier and protects you from surprise charges.
