Short answer: most electrical work beyond swapping a light fixture or a like-for-like device needs a permit in Chicago and nearly every suburb. New circuits, panel upgrades, service changes, EV chargers, remodels, and anything inside the walls are all permit work. The permit isn't red tape you route around — it's the paper trail that protects your insurance claim, your home sale, and the person who owns the house after you.
What usually needs a permit
- Panel and service upgrades — always. A panel upgrade or heavy-up is inspected work, full stop. (Costs and scope in our panel upgrade cost guide.)
- New circuits or outlets — adding a dedicated circuit for a kitchen, a hot tub, a window AC, or a home office.
- EV charger installs — a Level 2 charger is a new 240V circuit and one of the largest loads in the house. See the EV charger cost breakdown.
- Remodels and additions — any remodel wiring, kitchen/bath renovation, or finished basement.
- Rewiring — replacing old knob-and-tube or aluminum branch wiring.
What usually doesn't
Replacing a light fixture, a switch, or a receptacle with the same type in the same spot is typically maintenance, not permit work. The gray zone is bigger than most homeowners think, though — and Chicago is stricter than the suburbs. When in doubt, a 30-second phone call settles it for free: (872) 378-0533.
The Chicago wrinkle: conduit, not Romex
Here's the thing that trips up out-of-town contractors and DIYers: the City of Chicago does not allow non-metallic sheathed cable (Romex/NM) for permanent wiring. Inside city limits, branch wiring generally has to run in conduit (EMT). It's one of the oldest and strictest electrical codes in the country. Most suburbs follow the National Electrical Code and do permit cable — so what's legal in Evanston or Skokie may fail inspection three miles south in Chicago. A licensed electrician who works both sides of the line every week knows exactly where that boundary falls; that's a big part of what you're paying for.
Who can pull the permit
In Chicago, electrical permits are pulled by a licensed electrical contractor registered with the city — not the homeowner, in most cases. That's by design: the license on the permit is the city's assurance that a qualified person is responsible for the work. When we take a job, we pull the permit, meet the inspector, and handle the sign-off — it's included in the quote, never a surprise add-on.
What happens if you skip it
- Insurance. If unpermitted work is tied to a fire or a claim, the insurer can deny it. This is the expensive one.
- Selling the home. Unpermitted electrical work surfaces at inspection and can stall or kill a sale — or force you to open finished walls to prove the work was done right.
- Redoing it. The city can require unpermitted work to be inspected retroactively or torn out. Cheaper to do once, correctly.
The recurring theme: the permit is almost never the cost that matters. The cost that matters is what an unpermitted shortcut does to you two years later.
