Most Chicago homes need an electrical panel upgrade when the service is 100 amps or less and you plan to add a big load. That means an EV charger, a heat pump, central air, or a kitchen remodel. In ComEd’s service area, about two-thirds of homes have 100-amp service or smaller, based on a 2022 ComEd study.
Article Overview
- An electrical panel upgrade in Chicago can mean a new breaker box, more amps from ComEd, or both.
- Fuses, 60-amp or 100-amp service, and full panels are the most common warning signs.
- A 2022 ComEd study put a typical service upgrade at $4,000 to $6,000.
- Chicago requires a licensed electrical contractor and a city permit for this work.
- ComEd needs proof the work passed city inspection before it finishes its part.
What Is an Electrical Panel Upgrade?
Your electrical panel is the metal box full of breakers or fuses. It splits incoming power into circuits for each room.
Your electrical service is different. It is the set of wires and the meter that bring power from ComEd to the panel. Service size is rated in amps.
So there are two kinds of jobs:
- Panel replacement. The box gets swapped. The amps stay the same. This fixes old, failing, or full panels.
- Service upgrade. The amps go up, for example from 100 to 200. This needs new service wires, often a new meter base, and ComEd’s help.
When people search for an electrical panel upgrade in Chicago, they often need the second kind. Your project’s new loads decide which one you need.
7 Signs Your Chicago Home Needs a Panel Upgrade
Watch for these signs. Do not take the panel cover off yourself. The parts behind it stay live even with the main breaker off.
- You still have fuses. Screw-in fuses mean the system is decades old. A modern breaker panel is the usual fix.
- Your main breaker says 60 or 100. That number is your service size. It sets your ceiling for new appliances.
- Breakers trip often. A space heater or hair dryer should not knock out a room.
- There are no open slots. A full panel can’t take new circuits. Doubled-up wires on one breaker are a red flag.
- The panel is warm, buzzes, or smells burnt. Scorch marks belong in this group too. Call a licensed electrician right away.
- Lights dim when big loads start. Watch the lights when the AC or microwave kicks on.
- The panel brand gets flagged. Many home inspectors flag Federal Pacific Stab-Lok and Zinsco panels. Neither has a recall, so ask an electrician to check yours.
Which Projects Trigger a Panel Upgrade?
The trigger is new load. Every big appliance or new room adds demand. The panel and service must carry it all at once.
| Project | Why it adds load | What to ask |
|---|---|---|
| Level 2 EV charger | Draws power for hours at a time | Can my service carry it with the AC running? |
| Heat pump or central air | Large motor load in peak season | Does the load calculation still pass? |
| Induction or electric range | Needs a dedicated 240-volt circuit | Is there room for a new double breaker? |
| Electric dryer or water heater | Another 240-volt circuit | What happens if I add both? |
| Kitchen remodel | Code calls for several new circuits | How many new circuits does the plan need? |
| Basement finish or addition | New rooms need new circuits | Do I need a subpanel or a bigger service? |
The ComEd study gives a useful rule. Most 100-amp homes can swap two of three gas appliances to electric: range, dryer, and water heater. Swapping all three would likely need 200 amps. The study found 200 amps should cover most all-electric homes, even with an EV.
Why Older Chicago Homes Hit This Wall First
Chicago’s housing stock is old. Much of it was wired for lights and a radio, not for a modern kitchen.
Bungalows. Portage Park and Jefferson Park sit in the city’s Bungalow Belt. Many of these homes were built before World War II. Small services and fuse boxes are common finds.
Two-flats. Lincoln Park and Lakeview two-flats often have one panel per unit. A kitchen addition in one unit can push that panel past its limit. Older panels in these buildings often need an upgrade before a kitchen addition passes inspection.
Metal conduit. Chicago kept its strict metal conduit rules when it updated its electrical code in 2018. Plastic-sheathed cable used in many suburbs is not the norm here. That can add labor when an electrician runs new circuits.
Fixes come with the permit. The city’s permit terms say flaws in the existing system must be corrected under the permit. That includes grounding and bonding. So an older home’s upgrade can grow once the electrician opens things up.
How Much Does an Electrical Panel Upgrade in Chicago Cost?
The best local figures come from the 2022 ComEd study, prepared by Slipstream. It listed these typical costs:
| Job | Typical cost (2022 study) |
|---|---|
| Service upgrade (more amps) | $4,000 to $6,000 |
| Panel or subpanel swap, no service upgrade | About $1,000 |
| New dedicated circuit | About $400 |
Treat these as a starting point. The study itself says costs vary a lot from job to job. The figures are also from 2022, so today’s prices may be higher.
These factors push the price up:
- Moving the meter or panel to a new spot
- Metal conduit runs through finished walls
- Grounding and bonding fixes the city requires
- Patching plaster and drywall after the work
- Extra subpanels for a basement or addition
Before you compare bids for an electrical panel upgrade in Chicago, get at least two or three written quotes. Ask each electrician to list the permit, the load calculation, and the ComEd work as separate lines.
About tax credits: The federal 25C credit once covered part of a panel upgrade. That credit expired on December 31, 2025. Ask your electrician about current ComEd or state programs before you sign.

What Does Chicago Require for a Panel Upgrade?
Three groups touch this job: the electrician, the city, and ComEd.
A Chicago-licensed electrical contractor
The city’s rule is plain. A licensed electrical contractor must do all electrical work that needs a permit in Chicago. The city’s guidance lists no homeowner exemption. Our guide to choosing a licensed general contractor in Chicago explains how to check a license.
A city permit
Chicago handles many electrical permits through its online Express Permit Program. One listed electrical work type covers a new electrical service or service disconnecting means (panel). The contractor named on the permit must do the work. Work must follow the Chicago Electrical Code in effect when you apply.
For the bigger picture on permits, read our Chicago home renovation permit guide.
ComEd sign-off
ComEd needs confirmation that the work passed city inspection before it moves ahead. For new permanent home service, ComEd lists 6 to 18 weeks after it gets that confirmation. Ask your electrician whether your upgrade follows the same path. Then plan your remodel dates around it.
How Long Does an Electrical Panel Upgrade in Chicago Take?
Think of the timeline in four steps. Each one has its own clock.
- Quote and load calculation. The electrician visits, checks the existing setup, and sizes the new service.
- City permit. The contractor applies through the Express Permit Program. The city does not post a fixed review time.
- Install day. The power is off while the panel is swapped. Ask your electrician how long that window will be.
- Inspection and ComEd. A city inspector checks the work. ComEd then does its part on its own schedule.
The ComEd step is the one most likely to stretch your plans. Its posted range for new home service runs 6 to 18 weeks after inspection. If you have a remodel start date, tell the electrician at the first visit.
Which Size Do You Need: 100, 200, or 400 Amps?
Do not guess. A licensed electrician should run a load calculation. It adds up your lights, outlets, and appliances, then checks the total against the service size.
- 100 amps can work for a smaller home with gas heat, gas cooking, and no EV.
- 200 amps is the size the ComEd study found should cover most all-electric homes, even with an EV.
- Above 200 amps is for large homes, several EVs, or big future plans. The load calculation should prove the need.
Plan for the next ten years, not just this project. Adding capacity once costs less than doing the service twice.
How to Fit the Upgrade Into Your Remodel
An electrical panel upgrade in Chicago works best as an early step, not an afterthought. Here is a simple order:
- Get the load calculation first. Do it before you pick appliances.
- Book the electrician early. Permit, inspection, and ComEd steps all take time.
- Do the panel work before walls close. New circuits are cheaper to run through open framing.
- Ask for the power-off window in writing. Plan for food, work, and medical devices.
- Keep the permit and final inspection records. A future buyer’s inspector may ask for them.

Electrical Panel Upgrade FAQ
Do I need a permit to upgrade my electrical panel in Chicago?
Yes. A new service or panel is a listed permit work type in the city’s Express Permit Program. The work then needs a city inspection.
Can I replace my own electrical panel in Chicago?
No. The city says a licensed electrical contractor must do all electrical work that needs a permit. Its guidance lists no homeowner exemption.
Is 100-amp service enough for my home?
It can be, if you heat and cook with gas and have no EV. The 2022 ComEd study found most 100-amp homes can switch two of three gas appliances to electric. All three would likely need 200 amps.
How much does an electrical panel upgrade cost in Chicago?
A 2022 ComEd study put a typical service upgrade at $4,000 to $6,000. A panel swap without more amps was about $1,000. Prices may be higher now, so get written quotes.
Do I have to call ComEd myself?
Ask your electrician who handles it. ComEd’s new-service form asks for an electrician or project manager as the contact. ComEd also needs proof the work passed city inspection.
Is there a tax credit for a panel upgrade?
Not the federal one. The 25C credit covered panel upgrades, but it expired on December 31, 2025. Ask about current local programs.
