Electrical Panel Upgrade Permits

Updated 2026-10-30

Yes — plan on a permit. This Old House says “most panel upgrades require permits,” which cost $50–$300 depending on where you live, and Fixr says panel work requires a permit, an inspection and a licensed electrician. The rules are local: a city, county or state office issues the permit, your electrician usually pulls it (This Old House), an inspector checks the finished work, and the utility (PG&E, for example) reconnects power after the work passes.

Do you need a permit for an electrical panel upgrade?

The sources agree:

• Berkeley Lab’s 2024 brief: “Municipal or county permits typically are required to increase panel size.”
• Washington State’s Department of Labor & Industries (2015 homeowner publication) lists panelboards and meter bases or masts among work that requires a permit and inspection.
• Saint Paul, Minnesota requires an electrical permit for service upgrades and change-outs.

A same-size swap counts too: Saint Paul’s rules cover “a routine electrical panel replacement of the same amperage”; Washington lists panelboards as permit work while its list of exempt like-for-like replacements doesn’t include them; and PG&E asks for a project application even for a “replacement with no change to service (ex. old 100-amp panel to a new 100-amp panel).” Check with your local building department for the exact rule where you live.

Who pulls the permit — and why it should be your electrician

“Your electrician will usually handle the permitting process,” This Old House says. In Washington, the permit must be bought by whoever does the work; if you hire an electrical contractor, the contractor must buy it, and you can’t use a permit someone else bought.

Some states let homeowners pull their own permits (Fixr). Washington, for example, allows it only when the owner personally does the work. This site doesn’t give instructions for electrical work, and This Old House says panel upgrades are “not considered a do-it-yourself (DIY)-friendly project.” Hire a licensed electrician and have the permit in the electrician’s name.

Fixr notes that electricians may include the permit in their bid, “but it is a good idea to check.” Ask that the permit fee and inspection appear as lines on the written quote.

How the permit and inspection process works

1. Quote and scope. Washington advises getting a written quote for all the work.
2. Permit. The electrician applies with the city, county or state. In Saint Paul (rules revised July 2023), the permit is $85 for a service, covering existing circuits reconnected to the new panel, plus $15 per added or modified circuit.
3. Utility coordination. Berkeley Lab says the utility is usually involved in panel size upgrades to move the service wire to the new meter base and move or upgrade the meter. Some municipalities require an inspection by the local power company before work begins (Fixr), and PG&E asks for the building permit number when you request a disconnect and reconnect.
4. The work, done by the licensed electrician named on the permit.
5. Inspection. An inspector from the city or municipality inspects the work and approves it or asks for changes (Fixr). In Washington, the inspection must be requested before any work is covered, within 3 business days after the work is done or 1 business day after any part is energized, whichever comes first.
6. Power back on. PG&E says the work may require a local government inspection of the panel, and once it has passed and can be verified, PG&E can return and reconnect service.

Timing varies by utility and city; ask both before you schedule.

What it costs

The permit is a small part of the job — see 200 Amp Panel Upgrade Cost and Electrical Panel Replacement Cost for the full price, and How Much Does an Electrician Cost per Hour? for labor rates.

What the inspector checks

Requirements depend on the code edition your area has adopted. Saint Paul’s rules (revised July 2023) say service upgrades and panel replacements must meet the 2023 National Electrical Code, including:

• an outside emergency disconnect (2023 NEC 230.85) — required in Saint Paul even for a same-amperage panel replacement, so ask whether your city requires one and whether it’s in the quote;
• service grounding and bonding;
• clearances around the panel and for overhead service wires;
• strapping of conduit and cable, including the existing service conduit;
• correct breakers for shared-neutral circuits and barriers at the service terminals;
• a completed circuit directory that clearly identifies each circuit.

Saint Paul also says “all illegal or hazardous wiring noted during the inspection shall be repaired,” which can add to the job.

Berkeley Lab adds that under the 2023 National Electrical Code, upgrading the main panel triggers a requirement for a surge protective device, and that a service upgrade may reveal unsafe older equipment that must then be dealt with.

Risks of unpermitted panel work: insurance and home sales

Washington’s Department of Labor & Industries warns in its 2015 homeowner publication that the lack of a permit, inspection and approval “could affect the safety of your home or business, your ability to obtain financing, and your ability to sell your property, obtain insurance or collect on insurance claims.” It adds that missing paperwork for electrical work may cause problems when you sell. Under Washington’s current penalty schedule, starting work without the required permit or inspection costs $250 for a first offense, $1,000 for a second and $2,000 for each one after that. This Old House says improper work can lead to “code violations that may affect your home insurance coverage.”

What that means for your own policy is a question for your insurer. If you’re buying a house and the seller’s panel looks new, ask for the permit and the final inspection record.

How to look up your local permit rules

• Building department: search your city or county name plus “electrical permit.” Washington’s L&I notes that some cities run their own electrical inspections.
• Utility: ask what it needs before a disconnect and reconnect, and how long scheduling takes.
• Contractor license: check it with your state licensing board before you sign. Washington’s L&I also lets you look up a contractor’s past violations.
• Keep the paperwork: Washington’s L&I advises safeguarding your permits and approvals; keep the permit number and the final inspection approval with your house records.

Not sure whether old work in your house was permitted? Washington’s L&I suggests having a licensed electrical contractor review it, pull a permit and make any needed corrections before an inspection.
