Electrical Permit Guide for Maryland 2026
Permit costs, processing times, NEC edition, licensing authority, and the rules that are actually enforced in Maryland.
Quick Facts: Maryland Electrical Permits
Typical Permit Cost
$50 to $250 typical residential. Howard County base application is $50. Baltimore County, Montgomery County, Prince George's County, and Anne Arundel each publish their own fee schedules; service upgrades and panel replacements typically run $150 to $400 once plan review and inspection fees are totaled.
Processing Time
1 to 3 weeks in Baltimore County, Montgomery County, Prince George's County, Anne Arundel, and Howard; 3 to 10 business days in smaller jurisdictions. Same-day counter issuance is common for like-for-like panel replacements in Howard and Anne Arundel.
Online Portal Availability
Yes in Baltimore City (ePermits), Baltimore County (MyBaltimoreCounty), Montgomery County (ePermits via Department of Permitting Services), Prince George's County (Momentum), Anne Arundel County, and Howard County. Smaller Eastern Shore and Western Maryland jurisdictions run hybrid paper/online workflows.
Inspections
2 to 3 inspections typical: rough-in, service, and final.
Maryland Electrical Licensing
Maryland State Board of Master Electricians within the Division of Occupational and Professional Licensing, Maryland Department of Labor. State-issued Master Electrician license at the top; counties issue Journeyman and limited/low-voltage licenses below that, with the state Master Electrician typically required as a prerequisite.
Maryland has a unique two-layer licensing model. The state Master Electrician license is issued by the Maryland State Board of Master Electricians and requires seven years of electrical services experience under a licensed master plus passing a state exam based on the current NEC. The state Master Electrician license is a prerequisite for most county-level electrical licenses. Counties (Baltimore, Montgomery, PG, Anne Arundel, Howard) also issue Journeyman, limited, or low-voltage licenses; the state Board does not issue Journeyman licenses directly. Complaint investigation happens at the county level; the state Board handles discipline against the state license.
Electrical Code in Maryland
Business Occupations and Professions Article, Title 6 — Master Electricians (state license); county-adopted NEC (local enforcement) — Current Edition
2023 National Electrical Code — adopted by the Maryland State Board of Master Electricians in February 2023 as the examination basis, with most counties enforcing the 2023 NEC through their local code adoption (effective dates vary by county, typically mid-2023 through 2024). Some Eastern Shore counties still run on the 2020 NEC. Verify the enforced edition with the specific county building department before drawing plans.
Maryland does not have a single statewide electrical code enforcement framework. The state Board of Master Electricians regulates the state Master license and uses the current NEC for its exam basis; counties adopt and enforce the NEC locally through their building-code ordinances. Montgomery County, Baltimore County, Prince George's County, and Anne Arundel typically adopt on the NFPA cycle within 12 to 24 months. Baltimore County added a 10-hour continuing education requirement effective January 1, 2026, for county-registered electricians.

Maryland electrical permit thresholds are set by the county or municipal building department. The work types below universally trigger a permit across Baltimore City, Baltimore County, Montgomery, Prince George's, Anne Arundel, Howard, and other major Maryland jurisdictions.
Permit Required
- Any new circuit, branch, or feeder
- Main panel upgrade or service change
- EV charger install (Level 2, hardwired or NEMA 14-50)

Exempt from permit does not mean exempt from the code. Work still must comply with the edition in force at your address.
Maryland-Specific Rules You Should Know
Unique two-layer licensing — state Master, county Journeyman
Maryland is one of the only states where the state issues the Master Electrician license and the counties issue Journeyman and limited licenses below it. The state Master Electrician license is typically a prerequisite for obtaining the county electrical license. Complaints are handled by the county; the state Board acts on discipline against the state license when the county reprimands, suspends, or revokes.
Baltimore County CE requirement started January 1, 2026
Baltimore County electricians must complete 10 hours of continuing education every two years as part of the registration renewal process effective January 1, 2026. This is separate from the state Master Electrician CE requirements, which are tied to NEC/NFPA content.
2023 NEC on the state exam, county adoption varies
The Maryland State Board of Master Electricians adopted the 2023 NEC as the examination basis in February 2023. Most major counties (Montgomery, Baltimore, Prince George's, Anne Arundel, Howard) have adopted the 2023 NEC for local enforcement, with effective dates ranging from mid-2023 through 2024. Smaller Eastern Shore and Western Maryland counties may still enforce the 2020 NEC. Always verify the enforced edition with the specific county building department.
BGE, Pepco, Delmarva, Potomac Edison — four-utility interconnect map
Solar PV, battery storage, EV charger load additions over service capacity, and new service drops require a separate utility interconnection. BGE serves Baltimore City and Central Maryland; Pepco covers most of Montgomery and Prince George's; Delmarva Power serves the Eastern Shore; Potomac Edison covers Western Maryland. Each publishes its own interconnection and load-application requirements under Maryland PSC oversight.
Permit Cost Drivers in Maryland
Typical residential fee ranges. Actual fees vary by city and current-year schedule. Always verify at application.

| EV charger (Level 2, 240V) | $75 - $175 | Flat fee in most counties; Pepco and BGE load-letter typically required for sub-panel or service-level installs. |
| New dedicated circuit | $50 - $150 | Often bundled into a residential alteration permit. |
| Solar PV interconnect | $150 - $425 | System kW drives cost. BGE, Pepco, Delmarva, or Potomac Edison interconnection fee separate. |
| Whole-house rewire | $350 - $900 | Square footage and AFCI/GFCI retrofit scope dominate. Baltimore City and Montgomery County run higher. |
Maryland Electrical Permit FAQs
Can a Maryland homeowner pull an electrical permit?
Yes, in most Maryland counties on an owner-occupied single-family residence under the county's homeowner exemption. The homeowner must complete the work personally and sign an affidavit. Baltimore City, Baltimore County, and Montgomery County restrict scope and typically require a licensed electrician for service-side work. Confirm with your county permitting office before starting.
Which NEC edition does Maryland enforce in 2026?
The 2023 NEC is the examination basis set by the Maryland State Board of Master Electricians (adopted February 2023). Most major counties enforce the 2023 NEC for permitting (effective dates range from mid-2023 through 2024). Some Eastern Shore and Western Maryland counties still enforce the 2020 NEC. Always verify the enforced edition with the specific county building department.
What is the difference between the state Master Electrician license and county licenses?
The state Master Electrician license, issued by the Maryland State Board of Master Electricians, covers master-level electrical work statewide and is typically a prerequisite for the county electrical license. Counties (Baltimore, Montgomery, Prince George's, Anne Arundel, Howard) issue Journeyman, limited, or low-voltage licenses. The state Board does not issue Journeyman licenses directly. For county-level work, both a state Master and a county license may be required.
Do I need a separate utility interconnection for solar in Maryland?
Yes. BGE (Baltimore City and Central Maryland), Pepco (most of Montgomery and Prince George's), Delmarva Power (Eastern Shore), or Potomac Edison (Western Maryland) each require a separate interconnection agreement for grid-tied solar under Maryland Public Service Commission oversight. The interconnection runs alongside the county electrical permit and both must clear before energization.
What is the new Baltimore County continuing education requirement?
Effective January 1, 2026, Baltimore County electricians must complete 10 hours of continuing education every two years as part of the registration renewal process. This is in addition to the state Master Electrician CE required for the state license and is administered by Baltimore County's Department of Permits, Approvals, and Inspections.
What happens if I skip the permit in Montgomery County or Baltimore County?
Maryland counties enforce unpermitted electrical through stop-work orders, retroactive permit fees (often double the base), and utility refusal to energize service changes. Insurance commonly denies claims tied to unpermitted work, and Maryland real-estate seller disclosure requires surfacing unpermitted modifications at sale.
