EV Charger Permit Requirements in Maryland (2025)

Yes, you need a permit for a Level 2 or DC Fast Charger installation in Maryland. Permits are issued by your county or municipality, not the state. A licensed electrician must pull the permit in most jurisdictions. Level 1 (120V) on an existing circuit is usually exempt.

Quick Answer: Do You Need a Permit to Install an EV Charger in Maryland?

A permit is required for most EV charger installations in Maryland. Requirements vary by charger type:

Level 1 (120V, standard outlet): No separate permit is required when plugging into an existing, code-compliant outlet. A permit is required to add a new dedicated 120V circuit.

Level 2 (240V, 30A or 50A): An electrical permit is required in all Maryland jurisdictions. If the home's electrical panel needs an upgrade to support the new circuit, a separate panel upgrade permit is also required.

DC Fast Charger (DCFC / Level 3): An electrical permit and a building permit are required. A utility interconnection application must also be filed with the serving utility (BGE, Pepco, Delmarva Power, or SMECO). The Maryland Public Service Commission sets rules for utility interconnection.

Who issues the permit: Maryland does not have a statewide permit office. Permits are issued at the county or municipal level. Some cities, including Rockville and Gaithersburg, operate permit offices separate from their surrounding county.

Who can pull the permit: A licensed electrical contractor must apply for the permit in most Maryland jurisdictions. The Maryland Department of Labor (DLLR) issues electrician licenses. Homeowners generally cannot self-permit this work.

Typical timelines:

• Residential: 1 to 4 weeks from application to final inspection.
• Commercial: 4 to 12 weeks, depending on plan review complexity.

State guidance, not state permits: The Maryland Electric Vehicle Infrastructure Council (EVIC) and the Maryland Energy Administration (MEA) provide policy guidance and incentives, but do not issue permits. All installations must comply with the National Electrical Code (NEC) edition adopted by the state. The Maryland Department of Housing and Community Development can provide information on the current adopted code.

State-Level Legal Framework Governing EV Charger Installations

National Electrical Code Adoption

Maryland adopts the National Electrical Code (NEC) as the statewide minimum standard for electrical work. All permitted EV charger installations must comply with NEC Article 625, which governs electric vehicle charging systems. This covers wiring methods, circuit sizing, and equipment requirements. Consult the Maryland Department of Housing and Community Development (DHCD) for the currently adopted NEC edition and any scheduled updates.

Electrical Contractor Licensing

Maryland law requires that EV charger installations be performed by a licensed electrical contractor. The Maryland Department of Labor (DLLR) administers master and journeyman electrician licenses. Consult your county permit office to confirm specific requirements for who may pull the permit.

Utility Interconnection for DCFC

The Maryland Public Service Commission (PSC) has jurisdiction over utility interconnection standards and timelines for DCFC installations. An application must be filed with the utility before construction. If a utility fails to meet PSC-established timelines, a complaint can be filed with the PSC.

Right to Charge: HOA and Landlord Restrictions

Maryland law provides protections for residents in homeowners associations (HOAs) or condominiums seeking to install an EV charger for personal use. An association generally cannot unreasonably prohibit an installation. However, it may impose reasonable conditions related to code compliance, permits, and insurance. Consult the relevant Maryland statutes or a licensed attorney for the current scope of protections for both property owners and tenants.

Retail Electricity Supply Regulation

SB 1 (2024, Chapter 537) regulates retail electricity and gas suppliers, focusing on consumer protection. The law's direct effect on EV charging network operators who resell electricity is not fully defined. Public charging operators should consult the Maryland PSC to determine if their business model requires a retail supplier license.

Electrician Licensing Authority

The Maryland Department of Labor (DLLR) licenses master and journeyman electricians. You can verify an electrician's license at labor.maryland.gov. An installation performed by an unlicensed person will fail inspection and may void equipment warranties and homeowner's insurance coverage.

Permit Requirements by Charger Type and Installation Setting

Residential Level 2 (Single-Family)

A dedicated 240V circuit for a Level 2 charger requires an electrical permit in every Maryland county. The electrician must submit a load calculation showing the panel has adequate capacity. If the panel lacks capacity, a separate panel upgrade permit is required. In most jurisdictions, these are two separate applications with separate fees. Attached homes like townhouses may require additional documentation if wiring passes through shared walls.

Multifamily and HOA Installations

For unit-specific installations in a condo or apartment, the owner must first obtain association approval as required by Maryland's "right to charge" laws. The association cannot unreasonably deny this request. Once approved, the owner's electrician pulls an electrical permit through the local jurisdiction.

Common-area charging is treated as a commercial installation. Each charger must be on a separately metered circuit or use a submetering arrangement acceptable to the utility and the PSC. Wiring that runs through common areas requires coordination with the association and may require both a building permit and an electrical permit.

Commercial Level 2

Commercial Level 2 installations require both a building permit and an electrical permit. Installations must comply with state and federal accessibility standards, including the Maryland Accessibility Code. At least one accessible EVSE space must meet van-accessible dimensions for public charging stations. Signage requirements for accessible spaces also apply.

DC Fast Charger (DCFC / Level 3)

In addition to building and electrical permits, DCFC projects require several steps:

1. Submit a utility interconnection application to the serving utility (BGE, Pepco, Delmarva Power, or SMECO). Timelines vary by utility and project size. Consult the utility's interconnection portal for current timelines.
2. The utility will conduct a study to determine if the installation requires a distribution system upgrade. The applicant may be responsible for the costs of required upgrades.
3. Notify or file with the Maryland PSC if the installation meets certain capacity thresholds. Consult the PSC for current notification requirements.

Workplace Charger Installations

Workplace chargers follow the commercial permitting path. To claim state or federal incentives, retain all permit documentation. The MEA Charge Ahead Maryland program requires permit documentation as part of the rebate application.

What Triggers a Panel Upgrade Permit

A panel upgrade permit is required if the new EV charger circuit causes the total calculated load to exceed the panel's rated capacity, or if the panel is being physically replaced. The electrician's load calculation determines this. An undersized panel is a common reason for permit rejection or failed inspection.

County-by-County Permit Fees and Processing Timelines

Permit fees and processing times vary by jurisdiction. Maryland counties typically calculate fees based on a flat rate per circuit or as a percentage of the project's value. Verify all fees and timelines directly with the local permit office before starting a project.
