Electrical Permits for Homeowners: What Needs One and What Inspectors Check

Quick answer

The 2024 International Residential Code exempts only minor electrical work from permits: listed cord-and-plug temporary decorative lighting, reinstalling receptacles ("but not the outlets therefor"), replacing breakers of the required capacity in the same location, low-voltage work under 25 volts and 50 watts, and minor repairs like replacing lamps (IRC R105.2). New circuits, new outlets, panel replacements, service upgrades, EV chargers, generators, and solar all need permits. Inspectors check GFCI and AFCI protection (E3902), and on service work the outdoor emergency disconnect (E3601.8) and surge protection (E3606.5), which the 2024 IRC carries over from the 2023 NEC.

What the model code says

Most U.S. jurisdictions regulate home wiring through one of two documents: the National Electrical Code (NFPA 70, the “NEC”), or the electrical chapters of the International Residential Code (IRC Chapters 34 to 43), which are drawn from the NEC. The IRC electrical chapters “cover those wiring methods and materials most commonly encountered in the construction of one- and two-family dwellings,” and also allow “other wiring methods, materials and subject matter covered in NFPA 70” (E3401.1). They apply to services of 120/240 volts, 0 to 400 amps, single-phase (E3401.2).

NEC adoption is state by state and sometimes city by city. For example, the City of Saint Paul announced that the 2023 NEC applied to electrical permits obtained on or after July 1, 2023. NFPA maintains maps showing where each edition is enforced. Your jurisdiction’s edition decides the details below.

What is exempt

The 2024 IRC electrical exemptions (R105.2) are:

“Listed cord-and-plug connected temporary decorative lighting.”
“Reinstallation of attachment plug receptacles but not the outlets therefor.”
“Replacement of branch circuit overcurrent devices of the required capacity in the same location.”
“Electrical wiring, devices, appliances, apparatus or equipment operating at less than 25 volts and not capable of supplying more than 50 watts of energy.”
“Minor repair work, including the replacement of lamps or the connection of approved portable electrical equipment to approved permanently installed receptacles.”

The ordinary-repair allowance (R105.2.2) specifically excludes “addition to, alteration of, replacement or relocation of … electric wiring.” So new circuits, new outlet or switch locations, moving wiring, panel and service work, and hardwired equipment all need permits.

Protection inspectors check

GFCI (E3902, NEC 210.8). The 2024 IRC requires ground-fault protection for 125- to 250-volt receptacles in bathrooms, garages and accessory buildings, outdoors, crawl spaces, basements, kitchens, other areas with sinks and food-preparation provisions, within 6 feet of sinks, bathtubs, and showers, laundry areas, and indoor damp and wet locations. It also covers outlets supplying specific appliances, including dishwashers, electric ranges, wall ovens, cooktops, clothes dryers, microwave ovens, sump pumps, and high-pressure spray washers (E3902.12).

AFCI (E3902.21, NEC 210.12). Branch circuits supplying 120-volt, 10-, 15-, and 20-amp outlets in “kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreations rooms, closets, hallways, laundry areas and similar rooms or areas” need arc-fault protection. When branch-circuit wiring in those areas “is modified, replaced, or extended,” the circuit must be AFCI-protected, with a short exception for extensions of 6 feet or less without new outlets (E3902.22).

Emergency disconnect (E3601.8, NEC 230.85). For one- and two-family dwellings, service conductors must terminate in a disconnect “installed in a readily accessible outdoor location,” marked “EMERGENCY DISCONNECT” on a red label with white text.

Surge protection (E3606.5, NEC 230.67). “All services supplying one- and two-family dwelling units shall be provided with a surge-protective device,” rated at least 10 kA, in or next to the service equipment. “Where service equipment is replaced, all of the requirements of this section shall apply.”

Service size (E3602.1). For one-family dwellings, service conductors must be rated at least 100 amps.

EV chargers, generators, and batteries

EV charging (R317.6). “Where provided, electric vehicle charging systems shall be installed in accordance with NFPA 70,” listed to UL 2202, with supply equipment listed to UL 2594.
Standby generators (R331.1). Stationary engine generators must be listed to UL 2200, and their connection to premises wiring “shall be by means of a listed transfer switch.”
Battery storage (R330). Home energy storage systems have their own installation section covering listing (UL 9540), location, and protection.

Zoning, HOA rules, and setbacks

Most interior electrical work has no zoning component. Outdoor equipment can:

Generators may have setback, noise, and exhaust-location rules, and fuel-gas permits for natural gas or propane units.
EV chargers in driveways or outside walls rarely trigger zoning but may in historic districts.
HOAs may regulate visible equipment. Some states limit HOA restrictions on generators or EV charging, so check your state page.

Permits and inspections you can expect

Electrical permit, usually issued to a licensed electrician, or to a homeowner where allowed.
Rough-in inspection before walls or ceilings are closed, covering boxes, cable, grounding, and support.
Service inspection for panel and service work, coordinated with the utility for disconnect and reconnect.
Final inspection, covering devices, GFCI/AFCI protection, labeling, and covers.

What to prepare

Scope of work: circuits added or changed, fixture and outlet locations, and equipment ratings.
Panel information: existing service size, breaker spaces, and a load calculation for large additions such as EV chargers, heat pumps, and electric ranges.
Equipment specifications for chargers, generators, transfer switches, or batteries.
Licensing: your electrician’s license number, or homeowner permit eligibility.
Utility coordination for service changes.

How permit fees are calculated

Electrical permit fees are set locally, typically by:

Count: per circuit, outlet, fixture, or device.
Service size: a fee tier based on amperage for panel and service work.
Flat fees for common jobs such as EV chargers, generators, or panel replacements.
Valuation of the electrical work.

Check the fee schedule linked from your county’s profile in our directory.

Common mistakes

Treating new outlets as “replacements.” Only reinstalling existing receptacles is exempt.
Replacing receptacles without required GFCI protection in kitchens, baths, garages, laundry areas, and outdoors.
Extending circuits without AFCI protection in living areas.
Panel swaps without surge protection or the outdoor emergency disconnect where your edition requires them.
Backfeeding a generator without a listed transfer switch or interlock, which is a hazard to utility workers.
Covering wiring before the rough-in inspection.
Assuming the state homeowner exemption overrides local rules. Cities can still require permits and inspections.

State notes

Some states set a rule for this project statewide. These notes come from our state research; your city or county may add its own requirements.

Alabama: The state electrical licensing law does not apply to the owner of premises doing electrical work on those premises. A local permit and inspection may still be required. Source
Alaska: The 2020 National Electrical Code is the state minimum. State electrical inspection covers commercial structures and dwellings of three-plex and above (Anchorage and Fairbanks inspect locally). Electrical installation on residential property owned by the installer or immediate family and not intended for sale is exempt from electrical administrator licensing. Source
Arkansas: State law does not require a license for a person doing electrical work on their own primary residence, unless state law, rules or a local ordinance require one. The work must still meet the adopted National Electrical Code and any local permit and inspection rules. Source
Colorado: The 2026 National Electrical Code is the statewide minimum standard for electrical work from August 1, 2026. Permits are issued to a registered electrical contractor or to a homeowner doing their own work, and a contractor may not work under a homeowner's permit. Source
Connecticut: Owners may do electrical work in a single-family home they own and occupy without a state license, subject to the town building official's inspection and approval. Anyone else doing electrical work for the public needs a state electrical license. Source
Delaware: All electrical work not specifically exempt needs a certificate of inspection from a state-licensed electrical inspection agency. Homeowners doing their own wiring need a state homeowner's permit, which is not available for pool or hot tub wiring. Source
District of Columbia: Electrical permits are trade permits that DOB issues only to licensed and bonded master electricians. Homeowners cannot apply for them, even for their own home. Source
Florida: An owner may apply for the permit and do their own electrical work on a single-family or duplex residence for their own use and occupancy, not intended for sale or lease (F.S. 489.503(6)). Electrical work is not covered by the under-$7,500 permit exemption. Source
Hawaii: Electrical work that requires a license must be done by a licensed electrical contractor using electricians licensed under HRS chapter 448E, including on owner-builder projects. Permits and inspections come from the county building department. Source
Idaho: DOPL requires a permit for electrical work and inspects it, except in cities and counties that run their own electrical inspections. Homeowners may get a homeowner permit only for work they do themselves on their primary or secondary residence and related outbuildings. Work is installed to the 2023 NEC with Idaho amendments. Source
Indiana: There is no state electrical permit or state electrician license. Permits, inspections, and any contractor licensing are local. Wiring must meet the state electrical code, which is currently the 2009 Indiana Electrical Code (2008 NEC), or for one- and two-family homes, the electrical provisions of the Indiana Residential Code. A 2026 Indiana Electrical Code based on the 2023 NEC has been submitted as a final rule but is not yet in effect. Source
Iowa: Where no local electrical inspection program exists, a state electrical permit and inspection from DIAL is required for new single-family work that needs new service equipment, and for larger residential, commercial, and industrial work. Owners of an existing, homestead-qualified single-family principal residence may do their own wiring without a license. Source
Kentucky: Kentucky requires an electrical permit before electrical work starts, issued by the state or a local government with certified inspectors (KRS 227.480). Permits go to licensed electrical contractors, except that a homeowner or farmer may pull one for work on their own premises. Source
Maine: State law requires an Electricians' Examining Board permit for electrical installations, but there are exceptions. No board permit is needed for work in a single-family home by a licensed electrician, for work by an owner in an existing single-family home they own and occupy, or for minor repairs. It is also not needed where a town requires its own electrical permit by ordinance. An owner wiring a new single-family home they will occupy needs a single-family dwelling certificate and a state inspection before the wiring is covered. Source
Massachusetts: Electrical work follows the Massachusetts Electrical Code, 527 CMR 12.00, based on the 2026 NFPA 70 and effective April 24, 2026. Permits are issued by the local inspector of wires. Source
Michigan: The Michigan Electrical Code (2023 NEC, second printing, with Michigan amendments, effective March 12, 2024) governs electrical installations statewide. Electrical permits come from the local enforcing agency, or from LARA's Bureau of Construction Codes where no local agency enforces electrical. Source
Minnesota: Electrical work needs a permit and inspection throughout Minnesota, from DLI or from a city with its own electrical inspection program. Permits filed on or after August 17, 2026 must meet the 2026 National Electrical Code. Source
Montana: Electrical installations need an electrical permit from DLI or a certified local program, and a power supplier may not energize an installation without one (MCA 50-60-604, 50-60-605). Owners need no license for work on their own property or residence kept for their own use, but grid-tied generator work is excluded (MCA 37-68-103). Source
Nebraska: State Electrical Act rules apply statewide. A homeowner may wire their own principal residence, up to a single-family home, without a license. For a single-family home, state inspection is required when new service equipment is installed, and the inspection request must be filed at or before the start of work. Cities and counties with approved programs inspect instead of the state. Source
New Mexico: Homeowners may pull an electrical permit for their own primary residence only after CID approves a floor plan and panel schedule and the homeowner passes CID's homeowner electrical exam (75% to pass). Only the permittee may do the work (14.5.2.18 NMAC). Source
North Carolina: Adding, replacing or changing electrical wiring, devices, appliances or equipment needs a permit, though like-kind replacement of electrical devices and lighting fixtures is exempt under G.S. 160D-1110(c)(3). Permits come from the local inspections department. A homeowner may do electrical work on their own property that is not intended for rent, lease or sale (G.S. 87-43.1(5a)). Source
North Dakota: Statewide, the supervising electrician must file a wiring certificate before work starts on a new or altered service, a moved building, a mobile home service or feeder, or work costing more than $500. Homeowners may wire a home or farmstead they own and live in after applying to the State Electrical Board (N.D. Admin. Code 24.1-05-01-01). Source
Ohio: Residential electrical work follows RCO Chapter 34, which adopts the 2023 NEC with Ohio amendments. Small jobs are exempt from approval, such as replacing a breaker of the same size and type in the same place, minor repairs and low-voltage work under 25 volts and 50 watts (RCO 102.10). Source
Oklahoma: No state license is needed for electrical work on your own property or residence, except where a local ordinance requires one (59 O.S. § 1692(B)(3)). Where there is no local permit or inspector, electrical work must be reported to the CIB on its Notification of Work Without Permit form. Source
Oregon: Owners and their immediate family may do electrical work on residential or farm property the owner holds without a license, if the property is not intended for sale, exchange, lease or rent (ORS 479.540). The work must meet the 2026 Oregon Electrical Specialty Code (2026 NEC, effective October 1, 2026) and be permitted and inspected. Landlords may do only maintenance-level repairs on rentals. Source
South Carolina: An owner doing only minor electrical work is exempt from the building permit requirement (S.C. Code § 40-59-265). This covers reinstalling plug receptacles (not adding outlets), replacing a breaker of the required size in the same spot, low-voltage wiring under 25 volts and 50 watts, and replacing lamps. New circuits and other electrical work need a permit. Source
South Dakota: Electrical work must be inspected by the state Electrical Commission, or by Rapid City or Sioux Falls inside their limits. Homeowners may wire their own detached, owner-occupied single-family home or farmstead without a license, but need an approved homeowner permit before starting (SDCL 36-16-15). Source
Tennessee: In areas served by the state electrical program, a permit is required before installing wiring that must be inspected under Rule 0780-02-01-.04. A residential property owner can buy an individual-use permit for a home that is not for sale, lease or rent, and doesn't need to show a license. Source
Texas: State law exempts electrical work on a dwelling by a person who owns and resides in it from state licensing, but only for work not specifically regulated by a municipal ordinance (Occupations Code §1305.003(a)(6)). Cities can still require permits and licensed electricians. Texas Property Code §202.019 limits HOA restrictions on permanently installed standby electric generators. Source
Vermont: The Vermont Electrical Safety Rules (2023 NEC, effective November 5, 2025) do not apply to single-family owner-occupied homes. They do apply to rental homes, duplexes and rented ADUs, where an Electrical Work Notice must be validated before work starts and the work is inspected by the state or a municipal inspector. Source
Washington: Electrical work needs an electrical permit and inspection from L&I, or from the city if it runs its own program. Homeowners may do their own work at their residence or farm without a license (RCW 19.28.261), but must buy the permit themselves. Some minor work is exempt under WAC 296-46B-901. Source
West Virginia: The State Building Code adopts the 2020 NEC. In renovations of one- and two-family homes that add no square footage, AFCI protection is required only in bedrooms. If square footage is added but no new electrical service is installed, AFCI protection is not required (87CSR4). Owners may do electrical work on their own property without a state license (W. Va. Code § 29-3B-3). Source
Wisconsin: A residential owner may install, repair or maintain electrical wiring in a home they own and live in without a state electrician license, unless a local ordinance requires one (Wis. Stat. § 101.862(4)(a)). The work must follow the Wisconsin Electrical Code (2023 NEC, effective September 1, 2026), and local permit rules still apply. Source
Wyoming: Outside cities and counties with their own electrical enforcement, a state electrical wiring permit is required before starting new construction, or a remodel that needs the utility to disconnect and restore power (W.S. 35-9-120(e); DFPES rules ch. VII). Owners may do the work themselves on property they own or lease that is not for immediate resale. Source

Common questions

Do I need a permit to replace a light fixture or outlet?

Replacing lamps is exempt, and the IRC exempts 'reinstallation of attachment plug receptacles but not the outlets therefor' (R105.2). Many jurisdictions treat like-for-like replacement of a fixture or receptacle as a minor repair. Adding a new outlet, fixture location, or circuit is new work that needs a permit. Note that replacing receptacles in GFCI-required locations must provide GFCI protection.

Can I do my own electrical work?

It depends on state and local law. Some states let homeowners do electrical work on a home they own and live in, sometimes only with a homeowner permit and inspection. Others require a licensed electrician. Cities can be stricter than the state. Check your state page and ask your permit office.

Does replacing an electrical panel need a permit?

Yes, nearly everywhere. Under the 2024 IRC, when service equipment is replaced the surge-protection requirement applies (E3606.5.3), so ask your permit office whether it also requires the outdoor emergency disconnect (E3601.8) on a replacement. Coordinate with your utility for disconnection and meter work.

Do I need a permit for an EV charger?

A hardwired charger or a new 240-volt receptacle is new circuit work and needs an electrical permit. The 2024 IRC requires EV charging systems to be installed under NFPA 70 and listed to UL 2202, with supply equipment listed to UL 2594 (R317.6). A load calculation may be needed to confirm the panel and service can carry it.

Does a portable generator need a permit?

Using a portable generator with extension cords doesn't involve premises wiring. Connecting any generator to your house wiring does. The 2024 IRC requires stationary generators to be connected 'by means of a listed transfer switch' (R331.1), and an inlet or interlock for a portable generator is also electrical work that needs a permit in most places.
