How long it takes to get an electrical permit depends almost entirely on whether your project qualifies for over-the-counter approval or has to go through plan review. Simple residential work is often approved the same day or within a few business days. Projects that need plan review usually take one to three weeks for a typical home, two to four weeks for new construction or a full rewire, and four to six weeks or longer for complex commercial and industrial installations.
Same-Day and Over-the-Counter Permits
Straightforward residential projects frequently qualify for what building departments call over-the-counter permits. A panel upgrade, a single new circuit, or an EV charger installation at a single-family home may not require formal plan review at all. You fill out the application, pay the fee, and walk out with your permit the same day. Many online portals handle these in minutes.
If your project falls into this category, the honest answer to “how long” is about as long as it takes to complete the form and pay.
Standard Plan Review Timelines
Projects that need plan review follow a different clock. Your application first goes through an initial screening, where staff confirm it’s complete and all required documents are attached. That screening typically happens within a few business days. The application then moves to technical review, where a plan examiner or inspector evaluates your proposed work against the applicable electrical code and any local amendments.
All 50 states have adopted some version of the National Electrical Code, published by the National Fire Protection Association, as the foundation for their electrical safety standards. As of early 2026, 25 states enforce the 2023 edition, 15 states use the 2020 edition, and the remainder operate under older versions with local modifications.1National Fire Protection Association.

For a typical residential project that needs plan review, expect one to three weeks from submission to approval. New construction electrical plans, full house rewires, and multi-family projects generally take two to four weeks.
Commercial and Industrial Projects
Large commercial or industrial electrical installations with intricate system designs, high-voltage equipment, or engineered load calculations can push the review period to four to six weeks or longer. Projects that also require sign-off from other departments, such as zoning, fire safety, or historical preservation, add time because each department conducts its own independent review.
If your project touches any of those additional reviewers, build their timelines into your schedule from the start. Approvals happen in sequence, not in parallel.
What Slows Approval Down
The single biggest cause of delay is submitting an incomplete application. Missing documents, unclear scope descriptions, or diagrams that don’t match the written application all get the package kicked back for corrections. Each round-trip can add a week or more.
During technical review, the building department may issue a request for additional information if something in your plans needs clarification or correction. You’ll typically have 10 to 30 days to respond. The faster you reply, the faster the review resumes. Dragging your feet on these requests is the easiest way to turn a two-week review into a two-month wait.
Seasonal construction volume matters too. During peak building months, permit offices see a surge in applications and review times stretch. Filing during a slower period can shave days off your wait. Staffing also plays a role: some jurisdictions have dedicated electrical plan reviewers and move quickly, while others route everything through a smaller team handling all trade permits.
Ways to Shorten the Wait
Some building departments offer expedited plan review for an additional fee. The surcharge is commonly 50 percent or more of the standard plan review fee, but it can cut your wait time significantly. It’s most useful for commercial projects or residential work on a tight construction schedule where a few extra weeks of delay cost more than the surcharge. Not every jurisdiction offers it, and availability sometimes depends on staff capacity. Ask about expedited options before you submit so you can plan accordingly.
Beyond paying for speed, the two things most within your control are submitting a complete package the first time and responding fast when the reviewer asks for something. In-person submission is worth the trip if you want staff to confirm your application is complete before you leave the counter. Online portals are the fastest route for simple projects because you can upload documents, pay, and sometimes print your permit in a single session.
What to Have Ready Before You Apply
The review clock doesn’t really start until your application is accepted as complete. Having everything prepared in advance is the difference between a few days and a few weeks for the same project. Building departments generally ask for the same core items:
- A clear scope of work describing what you’re doing, whether it’s upgrading a panel, running new circuits, or rewiring a room.
- A site plan showing your property layout and where the electrical work will happen. Large projects may need a full set of engineered drawings.
- Electrical diagrams showing circuits, components, and load calculations, conforming to the applicable electrical code.
- Contractor information, including license number and contact details, if a licensed electrician is doing the work.
- Property owner name, address, and contact information.
Application forms are available on most building department websites or at their offices. For straightforward residential jobs, the paperwork is minimal. For larger projects, expect the documentation requirements to be more involved. Permit fees vary by jurisdiction and project scope, running roughly $50 to $300 for basic residential work and more for projects that trigger plan review.
How Long the Permit Itself Lasts
Getting the permit issued isn’t the end of the timeline you need to track. In most jurisdictions, an electrical permit expires if work doesn’t start within 180 days of issuance. Once work begins, the permit also expires if there’s a gap of 180 days or more between inspections. Extensions are available from the building official, but you’ll need to request one in writing and show a legitimate reason for the delay. Letting a permit lapse means reapplying and paying again.
Plan your application timing with that window in mind. Pulling a permit months before you’re actually ready to begin work can leave you reapplying for a permit you already paid for.
