Whether a Chicagoland renovation needs a permit depends on the work and the town. These answers cover the City of Chicago’s rules and how suburbs differ, based on the city’s own published guidance.
Do I need a permit to remodel my house in Chicago?
For most remodeling projects, yes — Chicago requires a building permit before most construction, demolition, rehabilitation, and repair work. You do not need one for finish work like painting, tiling, carpeting, or installing cabinets and countertops with no plumbing or electrical changes. You do need one to remove walls, touch anything structural, change an exit, or work on plumbing, electrical, heating, or gas systems.
Chicago's Department of Buildings publishes a full list of work that is exempt, including replacing up to 1,000 square feet of drywall (with no mechanical, electrical, or plumbing changes), in-kind window and door replacement on homes up to 4 stories, and roof repairs covering less than 25% of the roof surface. Exemptions may not apply to designated Chicago Landmark properties. When in doubt, check the city's Guide to Building Permits before starting.

Do I need a permit for a kitchen or bathroom remodel in Chicago?
It depends on how deep the remodel goes. In Chicago, swapping cabinets, countertops, tile, or paint — with no plumbing or electrical changes — needs no permit. Moving or adding plumbing or wiring, removing walls, or changing the room's layout does need one. Most plumbing work must also be performed by a licensed plumbing contractor.
A few small jobs are also exempt, like removing and reinstalling a toilet or stopping a leak. But replacing pipes with new material, rearranging fixtures, or any structural change triggers a permit. One narrow exception: the owner-occupant of a detached single-family home may personally do plumbing work on their own house — they still cannot hire an unlicensed person to do it. A vetted local Pro can tell you quickly which side of the line your project falls on; The Renovation Room can connect you with Chicago-area Pros who handle permits routinely.

Who pulls the building permit in Chicago — me or my contractor?
Either one can apply, depending on the permit type. In Chicago's online Express Permit Program, the property owner (or a licensed expediter) can submit the application; any licensed contractor listed must then accept the job by email before the permit is issued. Permits based on architectural drawings are submitted through E-Plan by the architect, engineer, or a city-licensed expediter.
Most building work in Chicago also requires a City-licensed general contractor on the permit. A homeowner may act as their own general contractor without a license only for work on their primary residence, with no more than 6 residential units and no building taller than 3 stories on the property — and can claim that exemption for only one property per calendar year.

What happens if I do renovation work without a permit in Chicago?
The city stops the job and fines you. When unpermitted work is discovered, Chicago issues a stop work order and posts warning notices, and work can only restart after you obtain the permit and pay the stop-work-order penalty — $1,000 or more, according to the City of Chicago Department of Buildings, which also says the permit fee is tripled in most cases after a stop work order.
The city can also open an administrative enforcement case or file a lawsuit to collect penalties. You will be required to correct anything that violates the Chicago Construction Codes or Zoning Ordinance — and may have to remove work that cannot be corrected — all at your own expense. The only exception is true emergency work, which still requires a permit application the next business day.

Can unpermitted work cause problems when I sell my home in Illinois?
Yes, it can. If the city issued a violation notice about the work and it has not been corrected, Illinois' Residential Real Property Disclosure Report requires you to disclose that to buyers before the contract is signed. And in Chicago, whenever unpermitted work is discovered, the city can require you to correct it — or remove it — at your own expense.
The state disclosure form makes sellers answer this item directly: "I have received notice of violation of local, state or federal laws or regulations relating to this property, which violation has not been corrected." Getting caught also makes permits more expensive: the City of Chicago says that when unpermitted work draws a stop work order, the fee for the permit issued afterward is tripled in most cases, on top of a $1,000-plus stop-work-order penalty. Fixing permits before listing is almost always cheaper than fixing them during a sale.

How long does it take to get a building permit in Chicago?
It depends on the project. Simple repairs and single-trade jobs use Chicago's online Express Permit Program, built to issue permits quickly without architectural plans. Projects that need an architect's drawings go through Standard Plan Review with an assigned city project manager — according to permit-expediting firm Permit Place's 2026 data, initial review there typically takes 15 to 30 business days, and 5 to 90 days overall depending on project type.
The Express Permit Program covers most repair work, reroofing, nonstructural interior alterations, window and door replacement, HVAC, plumbing, electrical, and porch or deck repair — you apply, pay, and download the permit certificate online. Standard Plan Review handles bigger jobs like additions and new construction, and every project also needs zoning approval first, which adds time.

Is Chicago's Easy Permit Process still a thing?
No — it was replaced. On November 6, 2023, Chicago's Department of Buildings retired the paper-based Easy Permit Process (along with the Solar Express and "Short Form" processes) and replaced them with the online Express Permit Program. You now apply, check status, pay fees, and download your permit certificate on the city's web portal, then print and post the certificate at the job site before work starts.
The Express Permit Program expanded on September 16, 2024 to cover more work types, including most electrical-only work and fire alarm systems. It uses guided online worktypes — repairs, reroofing, nonstructural interior alterations, window and door replacement, HVAC, plumbing, fences, porch and deck repair, and small solar systems — and shows inspection results online to the owner and listed contractors.

Do Chicago suburbs have different permit rules than the city?
Yes — every town sets its own rules. Chicago's permit system applies only inside the city limits. Each suburb runs its own building department with its own permit requirements, fees, and inspections — Oak Park, for example, handles its own permit applications, plan reviews, and inspections at the village level. In unincorporated Cook County, the county's Department of Building and Zoning issues permits and requires one for all work other than ordinary repairs.
Cook County's department covers only unincorporated areas and the Forest Preserves; if your home is inside any municipality, that village or city's rules control. So before starting a project in the suburbs, check with your local building department — work that is exempt in one town can need a permit in the next. Pros on The Renovation Room work in these suburbs regularly and can flag your town's permit steps early.
