Electrical permits

Permit rules are set locally, but as a general pattern, panel and service upgrades, new circuits, rewiring and most new equipment installs require a permit and an inspection, while like-for-like device swaps often do not. Permits commonly cost $50–$350, per Inch Calculator, and larger rewiring permits run $200–$900, per HomeGuide. Your city or county building department publishes the actual rules and fee schedule — that is the only authority that matters for your address.

A permit is not a tax on your project. It buys you an independent inspector who has no financial stake in the job signing off that it was done correctly. On electrical work, that is the only third-party check most homeowners will ever get.

Normally the licensed electrical contractor pulls the permit in their own name. That matters: it ties responsibility for the work to their license. If a contractor asks you to pull the permit as a homeowner, understand what you are being asked to do — you are taking on responsibility for work you did not perform. Some homeowners legitimately owner-permit their own residences where local rules allow it, but doing it as a favor to a contractor is a red flag.

The permit fee itself is a small share of a five-figure job — This Old House cites $50–$300 for panel work — so a contractor who offers to 'save you the permit' is usually saving themselves the inspection, not saving you money.

Unpermitted electrical work tends to surface later, and always at a bad moment: during a home sale, during a refinance appraisal, or during an insurance claim after a fire. Retroactive permitting is possible in many jurisdictions but usually means opening walls so an inspector can see the work.

How to choose

Call your building department before you sign: Ask two questions: does this scope need a permit, and what is the fee. Five minutes, and it makes every quote you receive easier to compare.
The contractor's name should be on the permit: Ask for the permit number once it is issued and verify it online if your jurisdiction offers lookup. It confirms both the permit and the license behind it.
Hold final payment until the inspection passes: Structure the contract so a meaningful final payment is due after the inspection sign-off, not after the truck leaves.
Keep the paperwork: Permit, inspection card, invoice and any load calculation. Put them with your home documents. Buyers and insurers ask for exactly these.
Treat 'we don't pull permits here' as disqualifying: For panel, service or new-circuit work, this is not a local quirk. It is a contractor avoiding scrutiny.

FAQ

Electrical permits — common questions

Still have a question? Talk to our team →

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

In many jurisdictions a like-for-like device or fixture replacement does not require a permit, while adding a new outlet or circuit does. This varies, and some cities are stricter than others. Confirm with your building department for your address rather than relying on a general answer.

How much does an electrical permit cost?

Typically $50–$350 depending on the locality, per Inch Calculator's 2026 guide. This Old House cites $50–$300 specifically for panel work, and HomeGuide puts whole-house rewiring permits at $200–$900. Your building department's published fee schedule is authoritative.

What happens if I find unpermitted electrical work in a house I'm buying?

Get a licensed electrician to inspect it and quote both the corrective work and any retroactive permitting. Then use that as a price negotiation. The risk is not just safety — an unpermitted panel can complicate your own resale and, in some cases, an insurance claim.

Can a homeowner pull their own electrical permit?

Some jurisdictions allow owner-builder permits on an owner-occupied primary residence, often with restrictions and an affidavit. Many do not. Even where allowed, it makes you responsible for the work. Check with your local building department.
