Permits And Timelines
Orientation — what this is
Big electrical work—panel upgrades, new circuits, major rewiring, EV charger installation—requires a permit and an inspection in virtually every jurisdiction. This isn't a gotcha from your local government; it exists because electrical work that fails inspection is electrical work that creates fire and electrocution hazards. When you call a licensed electrician, the permit and inspection are built into the cost and the timeline. Understanding what they are and why they take as long as they do keeps surprises off the table.
The permit process starts with paperwork: your electrician files the scope of work with your city or county, declaring what they're going to do, where they're going to do it, and how it will meet code. The jurisdiction reviews that paperwork—sometimes in 2 business days, sometimes in 2 weeks, depending on their backlog and complexity. Once approved, the electrician gets a permit number and a right-of-way to start. This phase is often the longest single delay, because you're waiting on someone else's schedule, not yours.
The permit and inspection step isn't paperwork for its own sake — it exists because electrical work that skips code review is how the hazards OSHA tracks actually happen. You can see what that standard covers at OSHA's electrical safety page.
Common sticking points
Why can't we just start right away?
The permit has to be filed before work begins—filing takes time (usually 2–5 business days), and the jurisdiction has to review it for code compliance before you get that green light. In some places, that review can push you to a week out. Your electrician won't start trenching or opening walls until the permit is approved, because any work done before approval has to be torn out and redone once it's denied.
What happens if I hire someone off the books to avoid the permit?
The work fails inspection when you sell or refinance (many lenders require it), your insurance won't cover damage from unpermitted work, and you're liable if someone gets hurt. Most states also fine homeowners for unpermitted electrical work—sometimes more than the permit itself would have cost. Licensed contractors include permit costs in their bid for this reason.
Can the inspector just show up, or do we schedule?
Most jurisdictions have you call for an inspection after the rough-in (wiring run, before drywall closes), and then again at final (everything complete). Some can fit you in the same week; others have a backlog and you're waiting 10–14 days. Your electrician will know your local inspector's schedule and plan for it. Falling behind on inspection scheduling is the single biggest timeline slip in residential electrical work.
What if the inspector finds something wrong?
The work gets tagged as "fail," the electrician fixes it, and you call for a re-inspection. If it's a small issue, that can happen within days. Big problems mean starting over on some sections. A good electrician knows the code and the inspector's patterns and avoids this, but it does happen—and it's why getting a properly licensed contractor matters.
