Chicago’s two-flat and bungalow belt was wired in the same decades Federal Pacific and Zinsco were selling load centers by the truckload. The insurance letter is often the first time a longtime owner hears the brand names. The second surprise is municipal: Chicago licenses electrical contractors itself. The Department of Buildings’ permitting portal is built around city trade licenses. A contractor who is legal in Naperville is not automatically legal to pull a Chicago electrical permit.
No Chicago shop is listed below. Several contractors write about Federal Pacific or Zinsco on their own sites — Quikwire in Des Plaines, and others aimed at the city or at multifamily owners — and Quikwire is still cited on /cost for a published replacement range. None of those pages print a City of Chicago electrical contractor license. Illinois does not issue a statewide electrician license the way California or Arizona does. Until a shop publishes both the job and a license number on their own site, this metro stays empty rather than guessing. Ask whoever you hire for the city license they will put on the permit.
Permits, said plainly
For a house in the City of Chicago, the electrician should be able to show a City of Chicago electrical contractor license and file through the city’s IPI / Department of Buildings process. For a house in Oak Park or Evanston, you are in that village’s building department. Jimco’s 2026 cost article lists Chicago DOB permit fees in a $150–$300 band; treat that as a contractor’s observation, then confirm on the city’s current fee schedule.
ComEd’s role
ComEd’s published service-and-meter requirements put the permit and inspection on the customer, and they say the company is usually barred from connecting work that has not passed the municipality. That is the opposite of “we’ll just swap it and tell the inspector later.” If the job is a service upgrade, expect a utility ticket as well as a city permit. If it is a same-amp panel change, still expect the city inspection — ComEd does not replace the Department of Buildings.
Cost without a fake Chicago average
Quikwire is the shop that publishes a simple $1,500–$3,000 standard-replacement range and separately says 100-to-200-amp work costs more. Jimco’s Illinois 2026 guide widens that to $1,500–$4,500. STS’s FPE page does not publish a replacement number. We are not averaging those into a third figure.
Winter scheduling is a local reality contractors mention in passing; we did not find a ComEd or DOB page that defines a seasonal outage window, so we are not inventing one.

Permit
City of Chicago Department of Buildings
Who pulls it: Electrical permits are filed by a City of Chicago–licensed electrical contractor through the city’s inspections and permitting portal. An Illinois state license alone is not what Chicago’s permit path is built around.
Suburban jobs (Oak Park, Evanston, Naperville, and the rest of Cook, DuPage, and Lake) use the local village or city building department. Do not assume a Chicago permit covers a house just outside the city limit.
Utility coordination
Commonwealth Edison (ComEd) for most of Chicago and the near suburbs
Who disconnects: ComEd’s service-and-meter requirements say the customer must obtain permits and inspections, and that ComEd is usually prohibited from connecting service that has not passed municipal inspection. Unauthorized meter tampering is a utility matter; the electrician coordinates any official disconnect.
Outage window: We did not find a ComEd page that publishes a standard residential panel-swap outage window. Local contractor pages describe many replacements as a single day, including inspection when the village schedules it that way.
Confirm the current ComEd contractor process for a service upgrade versus a same-amp panel change. Those are not always the same ticket.
What to hand the insurer
- Closed City of Chicago or suburban electrical permit
- Final inspection approval
- Invoice from the city-licensed (in Chicago) electrical contractor
- Photos if the carrier’s letter asks for them
Ask your agent for the exact list. Carriers do not publish a single national checklist.
Electricians who advertise this job
A shop is listed only if it advertises Federal Pacific, Zinsco, or insurance-driven panel replacement on its own site and prints a license number there. Trade-association locators already exist. We will not pad this list. Verify the license before you hire.
No listing in this metro met both bars on the pages we cited. Ask any electrician you call for the license number they will put on the permit, then look it up with the board named in the permit section. Do not treat a generic “licensed and insured” badge as enough.
