Quick answer: Chicago high-rise condo bathroom remodel rules are set by each building’s association, but most follow the same pattern. You submit an alteration packet to the board or management, your contractor provides a certificate of insurance naming the association, work runs only during set weekday hours, the service elevator must be booked, and any water shutoff is done by the building engineer in a short scheduled window. Approval often takes 2 to 6 weeks before work can start. AMG Proline prepares the packet, insurance and schedule for you. Call (708) 979-3298 or request a free estimate!

Remodeling a bathroom in a Chicago high-rise is a different job from remodeling one in a house. The tile and fixtures are the same, but the work sits inside a shared building with a board, a property manager, a building engineer, neighbors on every side and a plumbing riser that serves dozens of units. Most delays and surprise costs in condo bathrooms come from the building rules, not the construction. This guide walks through the rules you will meet, in the order you will meet them.
This guide goes with our bathroom remodeling in Chicago service. For the kitchen side of the same rules, read Kitchen Remodeling in a Chicago High-Rise: The Four-Hour Water Shutoff Window.

Chicago High-Rise Condo Bathroom Remodel Rules at a Glance
Every building writes its own rules, so treat this as a map of what to expect and check it against your association’s alteration policy.
| Rule area | What most buildings require | Who handles it |
|---|---|---|
| Board or management approval | Written alteration request with scope, drawings, product sheets and schedule | Owner signs, contractor prepares |
| Certificate of insurance | General liability, workers’ compensation and often umbrella coverage, with the association and management company named | Contractor’s insurance agent |
| Work hours | Weekdays only, commonly a window between about 8 or 9 AM and 4 or 5 PM, with quiet hours for noisy work | Contractor follows, management enforces |
| Elevator and loading dock | Service elevator booked ahead, pads installed, debris removed in sealed bags or carts | Contractor books with management |
| Water shutoffs | Scheduled with notice, done only by the building engineer, limited to a short window | Building engineer with contractor |
| Permits | City of Chicago permit for plumbing and electrical scope, copy filed with management | Contractor pulls and posts it |
| Deposits and fees | Refundable damage deposit, sometimes an elevator or review fee | Owner pays, building refunds after final check |
| Final sign-off | Inspection of common areas, sometimes a leak or pressure test of new work | Management and contractor |
The Board Approval Packet
Almost every Chicago high-rise requires written approval before any bathroom work that touches plumbing, waterproofing, flooring or walls. Starting without it can mean a stop-work order, fines, and in the worst case being told to restore the original bathroom at your cost. A complete packet is the fastest way through review, because incomplete packets go to the back of the line.
What a typical packet includes
- The building’s alteration request form, signed by the unit owner.
- A written scope of work that lists demolition, plumbing, electrical, waterproofing, tile and fixtures.
- A floor plan or drawing showing fixture locations before and after, with any changes marked.
- Product data sheets for the waterproofing membrane, floor underlayment, fixtures, valves and exhaust fan.
- The contractor’s license and certificate of insurance in the exact form the building asks for.
- A schedule with start date, working days, planned water shutoffs and elevator bookings.
- Drawings stamped by an architect or engineer, when the building requires them for larger changes such as moving a drain or opening a wall.
We assemble this packet for every condo project and send it to management on your behalf. It is part of how we give a fixed written price: the building rules are known before the number is set.
Certificate of Insurance Requirements
The certificate of insurance, often called a COI, is the document that holds up more condo projects than anything else. Buildings want proof that if a contractor floods the unit below or damages a hallway, there is insurance to pay for it. The requirements are specific, and a certificate with the wrong wording is usually rejected.
| Requirement | What buildings commonly ask for |
|---|---|
| General liability | Limits of at least $1 million per occurrence, and many downtown towers ask for $2 million or more |
| Umbrella or excess liability | Additional coverage on top of general liability, often several million dollars in larger buildings |
| Workers’ compensation | Statutory Illinois coverage plus employer’s liability for everyone working in the unit |
| Additional insured | The condominium association and the management company named exactly as the building specifies |
| Certificate holder | The association or management company, with the building’s exact legal name and address |
| Subcontractors | Each trade on site may need its own certificate, which is one reason in-house crews move faster |
Because our own crews handle demolition, waterproofing, tile and finish work, management usually receives one set of certificates instead of five. See In-House Trades vs. Subcontractors for why that matters, and How to Hire a Licensed Contractor in Illinois for what to check before you sign with anyone.
Your own insurance matters too
Your unit owner’s policy, usually an HO-6 policy, covers your interior finishes and your liability to neighbors. Many association declarations make the owner responsible for damage caused by work done in the unit. Call your agent before the project starts, confirm your coverage for water damage to other units, and ask whether the remodel will raise your interior value enough to need a higher limit.
Work Hours, Elevator Booking and Building Logistics
High-rise schedules are built around the building, not the crew. Losing an hour at each end of the day is normal, and it is one reason condo bathrooms take longer than the same bathroom in a house.
- Weekday work windows. Many buildings allow work roughly from 8 or 9 AM to 4 or 5 PM, Monday to Friday, with no weekends or holidays. Some limit loud work such as demolition, coring or tile cutting to a shorter window.
- Service elevator reservations. Demolition day, tile delivery, vanity and glass delivery each need a booked elevator time. Popular slots fill days or weeks ahead.
- Protection of common areas. Hallways get floor runners, elevators get padding, and doors to the unit stay closed to keep dust out of the corridor.
- Debris removal. Most buildings ban debris in the building’s trash chutes and dumpsters. The contractor hauls everything out the same day.
- Parking and access. Downtown loading docks have limited time slots, and crews often pay for nearby parking. These costs belong in the written price, not a surprise invoice.
- Move-in and move-out conflicts. Elevators reserved for residents moving take priority, especially at the end of the month.
If you plan to live in the unit during the work, read Living at Home During a Remodel in Chicago. In a condo with one bathroom, we plan the schedule so the toilet is out of service for as few days as possible.
Riser Shutoffs and Leak Liability
This is the part of a high-rise bathroom remodel that carries the most risk. In many older Chicago towers, a bathroom’s water supply comes from a vertical riser that also serves the units above and below. If the bathroom has no working shutoff valves inside the unit, the building engineer has to shut down the whole riser, and every unit on that stack loses water.
How riser shutoffs work
- Scheduled with notice. Buildings usually require advance notice, often 24 to 72 hours or more, and post notices for affected neighbors.
- Short windows. Shutoffs are often limited to a few hours, so the plumbing crew has to be ready with every fitting and valve on site.
- Engineer only. Contractors are almost never allowed to operate building valves themselves.
- New in-unit shutoffs. When the riser is off, we install new quarter-turn shutoff valves for the bathroom where the building allows it. Every future repair then avoids another riser shutdown.
Who pays when there is a leak
A leak in a high-rise does not stay in one unit. Water moves down through the slab, along pipe penetrations and into the units below, sometimes several floors. Under most Chicago condo declarations, damage that starts in a remodeled unit is the responsibility of that unit owner and their contractor, not the association. That is why buildings look so closely at the waterproofing plan and why some ask for a flood test of the new shower pan before tile goes down.
Not sure where your shutoffs are? We meet with your building engineer during the estimate visit and plan the shutoffs before the project starts.
What Layout Changes Are Allowed
The concrete structure of a high-rise sets hard limits on a bathroom layout. Some changes that are routine in a house are difficult or not allowed in a condo tower.
| Change | How likely it is to be approved | Why |
|---|---|---|
| Replacing fixtures in the same place | Usually approved | No changes to drains, stacks or the slab |
| Tub to walk-in shower | Often approved with a waterproofing plan | The drain usually stays near the same spot, but the new pan must be proven watertight |
| Moving the vanity a short distance | Often approved | Sink drains can usually be moved within the wall or along the floor |
| Moving the toilet | Often restricted | The toilet drain runs through the concrete slab into the unit below, and coring new holes needs engineering approval and scanning |
| Curbless or zero-entry shower | Depends on the building | The slab usually cannot be recessed, so the floor has to be built up instead |
| Moving walls or adding a second bathroom | Needs full review | Walls may hide risers, structure or fire separations |
| Hard tile or stone flooring | Usually approved with sound underlayment | Many buildings set a sound rating for flooring to protect the unit below |
Coring and post-tensioned slabs
Many Chicago high-rises use post-tensioned concrete slabs with steel tendons running through them under tension. Cutting one can be dangerous and very expensive to repair. Before any new hole is cored, buildings typically require ground-penetrating radar or X-ray scanning, engineering sign-off and access to the unit below. This is the main reason toilet relocations are so often refused.
Showers that fit the rules
A tub-to-shower conversion is the most common condo bathroom upgrade, and it usually fits well within building rules. Read our tub-to-shower conversion guide and see our walk-in shower installation service. If you want a low entry, see The Case for a Curbless Shower Before You Actually Need One, and we will tell you honestly how close your building lets us get. Frameless glass is usually fine in condos. See our glass shower doors service.
Ventilation in a tower
Most high-rise bathroom fans tie into a shared exhaust shaft or a building system, not a roof or wall vent of their own. The building may specify the fan type, the damper and how it connects. A fan that does not match the shaft can push moisture into the next unit. For how venting works in houses, see Why We Vent Bathroom Fans Through the Roof and Never Into the Soffit.
Permits for Condo Bathrooms in Chicago
Building approval and a city permit are two separate things. The association decides what it allows. The City of Chicago decides what needs a permit, usually any plumbing or electrical work beyond simple fixture swaps. Most buildings want a copy of the permit before work begins. Chicago also requires electrical wiring to run in conduit, which adds labor to every new circuit for lighting, a heated floor or an outlet. See our room-by-room permit guide for details. We pull the permits and schedule inspections for you.
A Realistic Condo Bathroom Timeline
| Stage | What happens | Typical time |
|---|---|---|
| Estimate and building review | Site visit, read the alteration rules, meet the engineer, fixed written price | 1 to 2 weeks |
| Design and selections | Tile, vanity, fixtures and glass chosen, product sheets gathered | 1 to 3 weeks |
| Board approval | Packet submitted, questions answered, approval letter issued | 2 to 6 weeks |
| City permit | Permit filed and issued, copy sent to management | Varies by scope |
| Construction | Demolition, plumbing, waterproofing, flood test, tile, fixtures, glass | 3 to 6 weeks |
| Final sign-off | City inspections, building walkthrough, damage deposit returned | 1 to 2 weeks |
From first call to finished bathroom, most Chicago condo projects take about 2 to 4 months, and approval is often the longest single wait. We order long-lead items such as custom vanities and glass while the board reviews the packet, so construction can start as soon as approval arrives. For pricing, see What a Bathroom Remodel Costs in Chicago.

Chicago Condo Bathroom Remodel FAQs
Do I need board approval to remodel my condo bathroom in Chicago?
Almost always, if the work touches plumbing, waterproofing, flooring or walls. Most associations require a written alteration request with a scope, drawings, product sheets, insurance and a schedule before work begins.
How long does condo board approval take?
Often 2 to 6 weeks, depending on how often the board or management reviews requests and whether the packet is complete. Projects that move drains or walls can take longer if engineering review is needed.
What insurance does my contractor need for a high-rise?
Most buildings ask for general liability, workers’ compensation and often umbrella coverage, with the association and management company named as additional insured. Limits vary by building, so the certificate must match the building’s exact requirements.
What hours can contractors work in a Chicago condo?
Usually weekdays only, often between about 8 or 9 AM and 4 or 5 PM. Many buildings limit loud work to a shorter window and do not allow work on weekends or holidays.
Who shuts off the water during a condo bathroom remodel?
The building engineer. Shutoffs are scheduled with notice and kept short. If the bathroom has no in-unit valves, the whole riser may be shut down, so we install new shutoff valves where the building allows.
Who is responsible if my remodel leaks into the unit below?
Under most condo declarations, the owner of the unit where the leak started is responsible, along with their contractor’s insurance. That is why careful waterproofing and a flood test of the shower pan matter so much in a high-rise.
Can I move the toilet in a high-rise condo?
Often not, or only with engineering approval. The toilet drain runs through the concrete slab, and coring a new hole usually requires scanning for tendons or rebar, engineer sign-off and access to the unit below.
Can I replace my tub with a walk-in shower in a condo?
Usually yes, with a waterproofing plan in the approval packet. The drain often stays in about the same place, which keeps the change simple for the building.
Can I put tile flooring in my condo bathroom?
In most buildings yes, but many require a sound-reducing underlayment that meets a set rating. Check the rules before choosing tile so the floor build-up is planned from the start.
Do I need a city permit as well as building approval?
Often yes. The association approves the work under its rules, and the City of Chicago issues permits for plumbing and electrical scope. We pull the permit and give management a copy.
How long does a high-rise bathroom remodel take?
Construction usually takes 3 to 6 weeks. With approval, permits and selections, the full project often runs about 2 to 4 months from first call to finish.
Is there a damage deposit for condo remodels?
Many buildings collect a refundable deposit before work starts and return it after a final check of hallways, elevators and common areas. Some also charge an elevator or review fee.
