High-Rise Condo Bathroom Remodeling FAQ

How is remodeling a high-rise condo bathroom different from remodeling a house?

A high-rise condo remodel must account for the building's rules, shared systems, access requirements, and construction procedures in addition to the bathroom itself.

A house typically gives the homeowner and contractor more control over construction access, deliveries, parking, utilities, work hours, and modifications. A condominium may have rules governing all of these areas.

High-rise bathrooms can also connect to shared plumbing stacks, building electrical systems, ventilation infrastructure, and other components that may limit what can be changed. Elevator reservations, material deliveries, debris removal, insurance documentation, common-area protection, inspections, and water shutoffs may also require coordination with building management.

As a result, successful condo remodeling requires planning for both the bathroom inside the unit and the building surrounding it. We also have a High-Rise Condo Bathroom Remodeling Planning Checklist in our Downloadable Resources to help you navigate this process as well as keep track of appointments, contacts and most importantly, your thoughts and ideas.

Do I need approval from my homeowners association (HOA) before remodeling?

Many condominium buildings require approval before bathroom remodeling begins, although the specific requirements depend on the building's governing documents and rules.

The condominium association or property management company may require drawings, a detailed scope of work, contractor information, insurance documentation, material specifications, permits, or other information before approving the project.

Some buildings distinguish between cosmetic work and projects involving plumbing, electrical, walls, ventilation, or other building systems. More extensive remodeling may require additional review.

Homeowners should contact their building management or association before construction begins rather than assuming that interior work is automatically exempt from building approval.

Are permits still required if I live in a condominium?

Yes, condominium ownership does not automatically eliminate the need for applicable building permits.

Whether a permit is required depends on the scope of the remodeling work and applicable Chicago requirements. Work involving plumbing, electrical, mechanical systems, structural components, or other regulated construction may require permits or inspections.

Building approval and municipal permits are also different requirements. Receiving approval from a condominium association does not necessarily mean that a Chicago permit is unnecessary.

Homeowners should have the contractor evaluate the proposed scope and determine which permits and inspections apply before construction starts.

Why do freight elevators need to be reserved?

Freight elevators often need to be reserved because remodeling materials, tools, debris, and equipment must be transported without disrupting normal building operations.

Condominium buildings commonly establish procedures for moving construction materials and debris through the building. A reserved freight elevator helps management control access, protect the elevator interior, and coordinate construction traffic.

Some buildings require protective padding, specific reservation periods, advance notice, or deposits. Elevator availability can also affect the contractor's daily schedule.

Failure to coordinate elevator access can cause delays, particularly when large materials such as tile, cabinetry, glass, plumbing fixtures, or demolition debris must move between the unit and the building's loading or disposal areas.

How are construction materials delivered to a condominium?

Construction materials are typically delivered through designated loading areas and transported to the unit using building-approved procedures.

The building may establish specific delivery hours, loading zones, elevator requirements, parking restrictions, and procedures for receiving materials.

Large or heavy deliveries may require advance scheduling with building management. Materials may also need to be temporarily staged in approved locations rather than common hallways, lobbies, or other areas.

The contractor should understand the building's delivery procedures before materials are ordered so that tile, cabinetry, glass, fixtures, and other products arrive when they can be properly received and moved into the unit.

Where do contractors park while working on my condo?

Contractor parking depends on the building and neighborhood, and many high-rise buildings have restrictions on construction-worker parking.

Some buildings provide loading areas or limited contractor parking, while others require workers to use public parking or street parking.

Parking restrictions should be determined before construction begins because contractors may need to transport tools, equipment, demolition debris, and materials to and from the building.

The contractor should also understand any rules regarding loading zones, vehicle size, parking permits, delivery vehicles, and time limits established by the building.

Can my building restrict when remodeling work can be performed?

Yes, condominium buildings commonly establish specific work hours and restrictions for remodeling activities.

Work-hour rules may limit when demolition, drilling, sawing, deliveries, debris removal, or other construction activities can occur. Buildings may impose additional restrictions on weekends, holidays, or particularly noisy activities.

These requirements can affect the contractor's daily schedule and the overall project timeline.

Before construction begins, homeowners should obtain the building's current construction rules and provide them to the contractor so the project schedule reflects the actual hours available for work.

Will water shutoffs affect other residents?

Potentially, yes; water shutoffs can affect other units when bathroom plumbing connects to shared building systems.

A toilet, shower, or sink may connect to water supply systems that serve more than one condominium unit. Building management may therefore need to coordinate shutoffs to minimize disruption to other residents.

Shutoffs should generally be scheduled in advance, and the contractor should understand which valves control the unit and which affect common or shared systems.

Homeowners should not assume that a plumbing shutoff inside the unit controls all of the water serving the bathroom.

Why is protecting common areas so important during a condo remodel?

Protecting common areas helps prevent damage to elevators, hallways, lobbies, doors, floors, walls, and other shared building property.

Construction materials, tools, demolition debris, and workers move through areas that other residents use every day. Without proper protection, these activities can cause scratches, dents, dust accumulation, or other damage.

Buildings may require protective floor coverings, elevator padding, corner protection, sealed debris containers, designated routes, or specific cleanup procedures.

A contractor who understands and follows these requirements helps minimize disruption, protect the building, and maintain a positive relationship with building management and other residents.

How can I help my condo bathroom remodel go smoothly?

The best way to help is to understand building requirements early, make decisions before construction, and maintain clear communication with your contractor and building management.

Before work begins, homeowners should obtain the building's remodeling rules, determine approval and permit requirements, understand work hours, reserve elevators when necessary, coordinate water shutoffs, and provide required contractor insurance documentation.

It is also helpful to finalize major selections such as tile, plumbing fixtures, cabinetry, glass, lighting, and flooring before they are needed on site.

A well-defined scope and organized schedule can reduce delays and help the contractor coordinate the project with building requirements.

Can I move plumbing in a high-rise condo?

Sometimes, but plumbing relocation can be limited by shared systems, building rules, structural conditions, and the location of existing plumbing connections.

Moving a sink may be relatively straightforward in some circumstances, while relocating a toilet or shower can be significantly more complicated because of drainage, venting, floor construction, and connections to shared plumbing stacks.

The proposed relocation should be evaluated against the building's plumbing infrastructure before the layout is finalized.

If the building restricts modifications to shared plumbing systems, the bathroom design may need to work within the existing fixture locations.

Can I move the toilet?

A toilet can sometimes be relocated, but the existing drain, venting, floor construction, plumbing stack, and building requirements must be evaluated first.

Toilet relocation typically requires modifying the waste drain as well as the water supply. In a high-rise building, the existing drain may connect to a shared vertical stack or other building infrastructure.

Concrete floors and structural conditions can make drain relocation more difficult than it would be in a wood-framed house.

The contractor should determine whether the proposed location can be properly connected before the homeowner commits to the new layout.

Can I change the shower location?

A shower can sometimes be relocated, but the feasibility depends on plumbing, drainage, waterproofing, floor construction, and building restrictions.

Moving the shower may require new supply lines, a relocated drain, a new shower valve, revised waterproofing, and changes to the bathroom floor or walls.

High-rise concrete floor systems can make drain relocation particularly challenging. Shared plumbing stacks may also limit where the new shower can be positioned.

The proposed location should be reviewed before finalizing the bathroom design and purchasing fixtures or materials.

Can I modify bathroom walls?

Some bathroom walls can be modified, but each wall should be evaluated for structure, utilities, building systems, and condominium restrictions before work begins.

A wall may contain plumbing, electrical wiring, ventilation components, structural elements, or other building infrastructure. Even a wall that appears to be nonstructural may contain systems that cannot be relocated easily.

Condominium rules may also restrict modifications to walls, particularly where they affect shared systems or structural components.

Any proposed wall removal, relocation, or modification should therefore be evaluated by the appropriate professionals and approved when required.

What are building work-hour restrictions?

Building work-hour restrictions define when contractors are permitted to perform remodeling activities within the condominium.

Rules commonly distinguish between ordinary construction activities and particularly noisy work such as demolition, drilling, cutting, or hammering.

Some buildings restrict work to weekdays, establish shorter hours on Saturdays, or prohibit construction on Sundays and holidays. Requirements vary considerably between buildings.

These restrictions should be identified before scheduling the project because they can affect the number of productive construction hours available each day and the overall project duration.

Who coordinates water shutoffs?

Water shutoffs are generally coordinated between the contractor, homeowner, and building management or the building's designated maintenance personnel.

The exact procedure depends on how the building's plumbing system is configured. Some shutoffs may control only the individual unit, while others can affect multiple units.

Building management may require advance notice, specific scheduling, or authorization before a shared water supply is shut down.

The contractor should identify the necessary shutoffs before plumbing work begins and coordinate with the appropriate building representative rather than operating shared valves without authorization.

What insurance does my contractor need?

The condominium building may require contractors to provide specific insurance documentation before they are permitted to work on the property.

Requirements vary by building, but may include general liability coverage, workers' compensation insurance, automobile coverage, certificates of insurance, and additional insured documentation.

The building's management company or condominium association should provide its current requirements before the contractor begins work.

Homeowners should not rely on assumptions about insurance requirements because incomplete documentation can delay approval or prevent the contractor from starting work.

Can I install a curbless shower?

A curbless shower may be possible, but the floor structure, drainage, waterproofing, slope, and building requirements must all accommodate the design.

A curbless shower requires the shower floor to transition with little or no raised threshold. Water must still be directed effectively toward the drain, which can require careful floor and drainage planning.

High-rise concrete floor construction can make achieving the necessary slope and drain configuration more difficult than in some single-family homes.

Waterproofing becomes particularly important because the shower floor can transition directly into the surrounding bathroom floor.

Can I install heated floors?

Heated bathroom floors can often be installed in a high-rise condo, provided the system is compatible with the building, electrical capacity, flooring, and floor assembly.

Electric radiant heating is commonly installed beneath compatible tile or stone flooring and controlled with a dedicated thermostat.

The installation requires electrical planning and coordination with the flooring system. The existing floor assembly should also be evaluated before installation.

Condominium requirements may affect electrical modifications or floor construction, so the proposed system should be reviewed before materials are purchased.

Can I change bathroom ventilation?

Possibly, but high-rise bathroom ventilation can connect to shared building systems that limit modifications.

A condominium bathroom may use a ventilation system designed as part of the building rather than an independently ducted residential system.

Changing the fan, ductwork, exhaust location, or other components may therefore require building approval or coordination with building management.

Homeowners should not assume that an existing ventilation opening can simply be relocated. The building's ventilation system and applicable requirements should be evaluated before changes are made.

What happens if the building has plumbing restrictions?

If building rules restrict plumbing modifications, the bathroom layout may need to be designed around the existing plumbing locations.

Plumbing restrictions may prevent or limit relocation of toilets, showers, drains, supply lines, or connections to shared stacks.

This does not necessarily prevent a successful renovation. The design can often be improved through changes to fixtures, cabinetry, storage, tile, lighting, shower configuration, and other features while retaining key plumbing locations.

The important step is identifying these restrictions early so that the design and budget are based on what can actually be constructed.

How long does a high-rise condo bathroom remodel take?

A high-rise condo bathroom remodel can commonly take several weeks, with more extensive projects taking longer because of construction, building coordination, approvals, and material logistics.

The actual construction period depends on the scope of demolition, plumbing and electrical work, waterproofing, tile installation, cabinetry, glass, inspections, and finish work.

High-rise projects may also require additional time for association approval, permits, elevator reservations, material deliveries, water shutoffs, inspections, and restricted work hours.

Material availability can affect the schedule as well. Custom cabinetry, specialty tile, stone, plumbing fixtures, and custom glass may have longer lead times.

Homeowners should therefore consider both the construction timeline and the pre-construction coordination period when planning a high-rise condo bathroom renovation. A terrific resource is our High-Rise Condo Bathroom Remodeling Planning Checklist found in our Downloadable Resources page.
