Do I Need a Permit to Remodel My Kitchen in Cook County, IL? [2026 Guide]

I've pulled kitchen permits in the south suburbs for 30 years, and the question I hear more than any other after "what's it going to cost" is "do we really need a permit for this?" Sometimes the homeowner is hoping I'll say no. Sometimes a different contractor already told them no. So let me give you the straight answer, village by village, and explain why Alpha Development Group pulls a permit on every job that needs one, no exceptions.

First, the thing almost everyone gets wrong: "Cook County" isn't who you deal with

Illinois doesn't have a statewide residential building code. Each municipality adopts its own (most of the south suburbs use a version of the International Residential Code with local amendments) and runs its own building department. That means if your home is inside the village limits of Orland Park, the Village of Orland Park Building Division at Village Hall issues your permit and sends its own inspectors. Same for Tinley Park, Oak Lawn, Palos Heights, Oak Forest, Lemont, and every other incorporated town.

The Cook County Department of Building and Zoning at 69 W. Washington Street in Chicago only has jurisdiction over unincorporated Cook County. Around here that mostly means pockets of unincorporated Orland Township, Palos Township, Lemont Township, and Bremen Township. If your mailing address says Orland Park but you don't pay a village tax levy on your property tax bill, you may be one of those pockets, and the county is your permit office.

Two quick ways to check:

• Your property tax bill. If there's a line for "Village of Orland Park" (or your town), you're incorporated. If the only local government lines are the township and the county, you're unincorporated.
• Call the village hall. Give them your address. They'll tell you in 30 seconds whether it's inside the village limits.

This matters because the county and the villages have different fees, different forms, different timelines, and different inspectors. A contractor who says "we'll pull the Cook County permit" for a home inside Tinley Park village limits doesn't know what they're doing.

"Unless you live in an unincorporated area, Cook County doesn't issue your permit. Your village does."

What triggers a kitchen remodel permit (and what doesn't)

The rules vary a little by village, but after 30 years the pattern is consistent enough that I can give you three buckets.

The gray zone is cabinets. Replacing cabinets with new ones in the same spots, with no wiring or plumbing changes, is cosmetic in most villages. But almost every real kitchen remodel ends up moving an outlet, adding a circuit for a new appliance, or shifting the sink a foot, and the moment that happens, you're in the middle column. My rule: if a wall is getting opened, plan on a permit.

How the south Cook County villages handle kitchen permits

These are the towns where we pull kitchen permits most often. The specifics change from time to time, so treat this as a map, not gospel, and confirm the current fee schedule with the village before you budget.

Orland Park

The Village of Orland Park Building Division handles permits and inspections out of Village Hall on Ravinia Avenue. Orland Park requires separate plumbing and electrical permits alongside the building permit, and it requires the plumbing contractor to hold an Illinois plumbing license and the electrical contractor to be registered with the village. Plan review on a standard kitchen usually runs 1 to 2 weeks. Orland Park inspectors are thorough about GFCI and AFCI protection and about range-hood venting, so make sure your contractor's plans show both. Most of the 1970s to 1990s homes in Orland Park have a wall between the kitchen and family room that homeowners want gone, and a good share of those are load-bearing, which pushes the project into the engineering column.

Tinley Park

The Village of Tinley Park Building Department is efficient and used to a high volume of kitchen remodels. Expect the same building-plus-trade permit structure, contractor registration, and a 1 to 2 week review for a kitchen without structural work. Tinley Park is strict about work not starting before the permit is posted, and the village does drive-by checks when it sees a dumpster in a driveway.

Oak Lawn

Oak Lawn's housing stock is older on average (lots of 1950s and 1960s brick ranches and Georgians), which means kitchen remodels there routinely uncover 60-amp service, ungrounded two-wire circuits, and galvanized supply lines. The Village of Oak Lawn's inspectors will require those to be brought up to current code where the work touches them. Budget for it, and expect the electrical permit to be the bigger piece of the review.

Palos Heights and Oak Forest

Both villages run smaller building departments with straightforward kitchen permit processes. Palos Heights in particular sees a lot of split-level and raised-ranch kitchen openings, and the village requires engineering on any bearing-wall removal. Oak Forest's process is quick for trade-only permits (a plumbing or electrical permit on its own can be issued in days).

Lemont

Lemont straddles Cook, DuPage, and Will Counties, but if you're inside the village limits, the Village of Lemont Building Department issues your permit regardless of county. Lemont has a historic downtown district where exterior changes get extra review, but interior kitchen work follows the standard process.

Unincorporated Cook County

If you're in unincorporated Orland, Palos, Lemont, or Bremen Township, you apply through the Cook County Department of Building and Zoning. The county's process is slower than the villages, more paperwork-heavy, and inspections are scheduled through a central office rather than a local hall. Plan on 3 to 6 weeks and a contractor who has worked with the county before.

A note on our neighbors to the south and west: Homer Glen, Mokena, Frankfort, and New Lenox are in Will County and run their own village permit offices. Naperville handles its own permits through the City of Naperville Building Division no matter which county the home is in. I cover those in our Naperville kitchen guide and Frankfort bathroom guide.

What a kitchen permit actually costs

Permit fees are the cheapest part of a remodel and the one homeowners worry about most. For a full kitchen in a south Cook County village in 2026, here's what to expect:

• Building permit: $75 to $350, often calculated as a base fee plus a percentage of the project's estimated value (commonly 1 to 2 percent), sometimes capped.
• Plumbing permit: $50 to $200, sometimes per fixture.
• Electrical permit: $50 to $200, sometimes per circuit or per opening.
• Structural engineering (if a bearing wall comes out): $600 to $1,500 for the engineer's stamped drawing, paid to the engineer rather than the village.
• Re-inspection fees: $50 to $150 each time an inspection fails and has to be redone. A good contractor never pays these.

All in, a typical permitted kitchen with plumbing and electrical relocation in Orland Park or Tinley Park lands around $300 to $600 in village fees. On a $45,000 remodel, that's about one percent. At ADG, permit fees are passed through at cost and show up on the receipts, same as every other line.

What a permitted kitchen remodel looks like, week by week

Homeowners sometimes imagine a permit means an inspector standing over the crew every day. It doesn't. Here's how it actually goes on a mid-range kitchen:

1. Before demo: application and plan review (1 to 3 weeks). We submit the permit application, a floor plan showing existing and proposed layouts, the electrical and plumbing scope, and contractor license and insurance documents. The village reviews and either approves or sends back comments. Meanwhile, cabinets and countertops get ordered, so this time isn't wasted.
2. Week 1: demo and rough-in. Permit gets posted in the front window. Old cabinets come out, walls open up, new supply lines, drains, and circuits go in.
3. End of week 1 or start of week 2: rough plumbing and rough electrical inspections. The inspector checks pipe sizing, venting, wire gauge, box fill, GFCI and AFCI protection, and that everything matches the approved plan. Nothing gets covered until these pass. If a wall was removed, framing gets inspected here too.
4. Weeks 2 to 4: close up and finish. Drywall, paint, cabinets, countertops, backsplash, flooring, fixtures, appliances.
5. Final inspection. The inspector confirms fixtures are connected, outlets are live and protected, the hood vents where it should, and the finished kitchen matches the plan. The permit closes, and you get a record on file with the village that the work was done to code.

Total inspector time in your house across the whole project: maybe an hour. That hour is what protects you.

The transparency problem with "no permit needed"

When a contractor tells you a full kitchen doesn't need a permit, one of three things is true. They don't know the rules. They know and don't want an inspector looking at their rough-in. Or they aren't licensed to pull one. None of those is a contractor you want opening your walls.

This isn't about liking paperwork. It's that I've been called into too many kitchens to fix what an unpermitted job left behind: a range circuit on 14-gauge wire, a dishwasher drain with no air gap, a beam sized by guesswork. The inspection is a second set of eyes on work you'll live with for 20 years. I want that second set of eyes.

What happens if you skip the permit

I'll be direct, because homeowners ask, and because a lot of contractors soft-pedal this.

1. Stop-work order and fines. Villages find out. Neighbors call, inspectors notice dumpsters, and building departments compare permit records to what they see. A stop-work order freezes the job mid-demo, and most villages charge a penalty (often double the permit fee, sometimes more) to issue the permit after the fact.
2. Denied insurance claims. If an unpermitted circuit starts a fire or an unpermitted drain floods the basement, your homeowner's insurance carrier can deny the claim on the grounds that the work was not code-compliant. This is the one that turns a $500 permit into a $50,000 problem.
3. A disclosure problem when you sell. The Illinois Residential Real Property Disclosure Report asks about known code violations, and buyers' attorneys and inspectors in the south suburbs routinely request permit history from the village. Unpermitted kitchen work is a common reason for renegotiated prices, seller credits, or a deal falling apart the week before closing.
4. Opening the walls back up. The village can require you to expose the unpermitted work for inspection, which means cutting into finished drywall, tile, and cabinetry. In the worst case, they require removal. I've seen a homeowner pay for the same kitchen twice.

Red flags when you're comparing contractors

If you hear any of these, walk away:

1. "We'll skip the permit to save you money and time." The permit is one percent of the project. The time is two weeks you'd spend waiting on cabinets anyway.
2. "You should pull the permit yourself as the homeowner." That usually means the contractor can't. In Illinois, plumbing must be done by a licensed plumber, and most villages require registered electrical contractors. An owner-pulled permit also puts the liability for failed inspections on you.
3. "We'll pull the Cook County permit" for a home inside village limits. They don't know the jurisdiction, which means they don't know the local code either.
4. No plan drawing. Villages want a floor plan with the existing and proposed layout. A contractor who can't produce one isn't planning the job in enough detail to price it honestly, either.

How to make the permit process painless

A few things I tell every client at the first walkthrough:

Decide your scope before applying. Every change after the permit is issued may need a revision, and revisions cost time. Know where the sink, island, range, and outlets are going before we submit.

Use the review window. The 1 to 3 weeks of plan review is when cabinets and countertops get ordered. On a well-run job, the permit is issued right around when the materials land, and nobody waits on anybody.

Keep the paperwork. When the final inspection passes, ask for the closed permit record. Put it with your closing documents. When you sell, it's the first thing a buyer's attorney will ask for, and having it turns a question into a selling point.

Ask your contractor which villages they work in. A contractor who pulls permits in Orland Park and Tinley Park every month knows what those plan reviewers want to see. That local familiarity is worth more than any fee schedule.
