Condo Bathroom Remodel in Chicago: Board Approval and Cost

In a Chicago condo, a bathroom remodel needs two approvals, not one: your association’s and the City’s. The association’s written approval comes first, because the City’s Express Permit application asks for a letter from the association. Every building sets its own rules for work hours, elevators, insurance and plumbing, so the biggest drivers of your timeline and extra cost are usually in your building’s rule packet, not in the bathroom itself.

Updated October 22, 2026. Built from the Illinois Condominium Property Act, the City of Chicago and the published rules of Chicago condo buildings, linked below. This is general information, not legal advice; your declaration and bylaws, and your association’s attorney, have the final word.

Step 1: Read the documents that govern your unit

The Illinois Condominium Property Act (765 ILCS 605) sets the framework, and your association’s own documents fill in the details. The state’s Condo Unit Owner’s Rights and Responsibilities Handbook explains the hierarchy: the declaration (the recorded document that creates the association), the bylaws, and the rules and regulations the board adopts. Where the governing documents conflict with the Act, the Act controls.

Three things to find before you talk to any remodeler:

• The declaration’s alteration clause. The state handbook notes that declarations generally bar owners from altering common or limited common elements, including those inside the owner’s unit, without written board approval. An owner also may not do anything in the unit that jeopardizes other property in the building or interferes with other owners’ use of it.
• The remodeling or construction rules. Most Chicago buildings publish a separate packet. Ask the property manager for the current version.
• Who owns what. The Act defines a unit as the part of the property designed for independent use and common elements as everything else. Where your unit ends, and whether the shower valve, the pipes in the wall and the stack behind your bathroom belong to you or to the association, is spelled out in your declaration, not in this guide.

Step 2: Get board approval in writing

The Act gives the board the power to adopt rules covering the details of how the property is operated and used, after a meeting of unit owners called for that purpose, and the board also has a right of access to units for maintenance and repair of common elements. In practice, that means your building’s approval process is whatever its rules say it is. Published Chicago packets show how much it varies:

A complete submission typically includes a written scope of work, a schedule, the names and licenses of the contractors, proof of insurance, and, where the City requires them, permits. Use the packet as a checklist and hand it to every remodeler you interview. A remodeler who has worked in your building will know it; one who has not should read it before pricing the job.

Keep the signed approval. The Act’s disclosure rules for a unit sale include a statement that improvements made by prior owners are believed in good faith to comply with the condominium instruments, so you or a later owner may be asked for it.

Step 3: Know the rules that apply to the building, not just the unit

Risers, stacks and shared systems

The pipes in the wall behind a condo bathroom often serve units above and below. That is why building rules often forbid touching risers, stacks and vents, and require a building engineer to coordinate any water shutoff. Plan the bathroom around the existing plumbing locations where you can. Moving a toilet or shower drain is a bigger conversation in a condo than in a house.

The City’s Express Permit does not cover work involving heating or cooling equipment that serves common areas or more than one unit, and the area of work is capped at 500 square feet for work in common areas or work affecting more than one unit. Drawings by an Illinois-licensed architect or structural engineer are required for work in a common area or in more than one unit.

Structure

Moving or removing walls changes the permit path. For a single residential unit, the Express Permit Program requires drawings from an Illinois-licensed architect or structural engineer when you relocate doorways or walls other than closets. In a concrete high-rise, your association may also require its own engineer’s review, as one Chicago building’s packet does for any change to slabs, columns or curtain wall.

Waterproofing and leaks

A leak in a condo damages someone else’s home. Section 12 of the Act lets the board assess the association’s insurance deductible against owners from whose units the damage originated, and lets it require owners to carry insurance for damage their negligence causes to other units. Careful waterproofing and a pressure-tested shower pan are not upgrades in a condo; they are risk control.

Insurance: three separate policies to check

1. Your contractors’ insurance. Buildings typically require certificates of insurance naming the association, its board and the managing agent as additional insureds, and that certificate must be on file before any contractor enters. Expect to ask your remodeler for it.
2. Your own policy. The Act says the association’s master policy need not cover improvements and betterments that owners install, which it defines to include fixtures, built-in cabinets and other alterations or upgrades. Ask your insurance agent whether your unit-owner policy covers the new bathroom at its remodeled value.
3. Your building’s minimums. Some buildings require owners to carry a minimum liability limit during construction. One Chicago building’s rules set $1,000,000.

Noise and neighbors

Two layers apply. The building’s rules usually set the work hours (see the table above) and often require notice to neighbors before noisy work. Separately, the Chicago Municipal Code (8-32-140) bars using fuel- or electric-powered tools for building, repair or demolition work between 8 p.m. and 8 a.m. within 600 feet of a residential building, with fines starting at $1,000 for a first violation. Building rules are almost always stricter than the City’s, so they are the ones that govern your schedule.

City permit: where the association letter fits

Most condo bathroom remodels that replace plumbing fixtures or change wiring need a City permit, and many qualify for the Express Permit Program. For work on condominium property, including work inside a single unit, the application must include an association approval letter that briefly describes the work (the City’s example is “interior renovations in unit 9A”) and is signed by an authorized representative, such as a property manager or an officer. The City also requires a licensed general contractor, and licensed electrical and plumbing contractors for those trades. The full rules, fees and exemptions are in do you need a permit to remodel a bathroom in Chicago?, and you can check licenses with how to verify a Chicago contractor license.

Condos built before 1978 also fall under federal lead-safe rules for paid renovation work that disturbs paint; see lead-safe remodeling in pre-1978 Chicago homes.

How condo rules affect cost and timeline

We do not have a verified Chicago price for “the condo premium,” and any single number would hide the real variables. What the sources above show is where condo projects pick up extra time and cost compared with a house:

• Weeks before demolition. Board meeting cycles, lead-time rules and certificate-of-insurance paperwork all happen before the first day of work.
• Fewer working hours and days. Limited hours, blackout dates and no weekend noise stretch the same job over more calendar days.
• Logistics. Reserved service elevators, loading-dock slots, floor and elevator protection, and carrying debris out of a high-rise all take labor.
• Deposits, fees and engineer coordination. Some buildings charge deposits or require their engineer to attend shutoffs.
• Design limits. Fixed plumbing locations push you toward replacing in place rather than rearranging.

Ask each remodeler to list these items separately in an itemized written scope and price, and to say how many working days the job needs once approval is in hand.

Checklist before you sign anything

1. Get the declaration, bylaws and current remodeling rules from the property manager.
2. Confirm what is a common element where your plumbing runs, and what the board must approve.
3. Interview remodelers who read the packet. Ask whether they have worked in your building or similar ones.
4. Submit the package in time for the board’s meeting cycle and get the approval, and the association letter for the City, in writing.
5. Collect certificates of insurance in the form your building requires, and confirm your own policy.
6. Reserve the elevator and notify neighbors as the rules require.
7. Have the contractor apply for the permit with the association letter attached.

Frequently asked questions

Do I need condo board approval to remodel my bathroom in Chicago?

Usually yes for work that touches plumbing, wiring or common elements. Declarations generally bar alterations to common elements without written board approval, and the City's Express Permit application asks for an association approval letter. Check your declaration and remodeling rules.

What does the City of Chicago need from my condo association?

For work on condominium property, including inside one unit, the Express Permit application needs an association approval letter that briefly describes the work and is signed by an authorized representative, such as a property manager or officer.

What hours can contractors work in a Chicago condo?

The building sets them. Published Chicago rules vary, for example 8:30 a.m. to 5 p.m. on weekdays in one building and 8 a.m. to 5 p.m. Monday to Saturday in another. The City also bars powered construction tools from 8 p.m. to 8 a.m. within 600 feet of a residential building.

Can I move the toilet or shower in a condo?

Sometimes, but many buildings restrict changes to risers, stacks and vents, and the declaration decides which pipes are common elements. Ask the board and a licensed plumber before designing a new layout.

Does the association's insurance cover my new bathroom?

Not necessarily. Under the Illinois Condominium Property Act, the master policy need not cover improvements and betterments that owners install. Ask your insurance agent about your own unit-owner coverage.

Who is responsible if my remodel leaks into the unit below?

You may be. The Act lets a board assess the association's deductible against owners from whose units damage originated, and building rules often require contractor insurance naming the association.

How long does condo approval take?

It depends on the board's meeting schedule and your building's rules. Published rules show monthly board meetings with submission deadlines, and at least one building requires approval 30 days before work starts. Ask the property manager.
