Condo Bathroom Renovation Ottawa: 2026 Board Approval Guide

By Curtis McGrath, Project Coordinator | 18 years renovation experience | Bytown Better Bathtubs and Showers | Updated July 2026

A condo bathroom is not yours from the studs out. Your unit ends where the building’s shared systems begin, and much of what makes a bathroom work, the plumbing stack, the vents, and the walls between units, belongs to the corporation. That is why a condo bathroom renovation runs on approvals and access rules a house never sees. We renovate condo bathrooms across Ottawa, Kanata, Nepean, Barrhaven, and Orleans, and the first thing we ask for is your declaration. For the full pricing picture, our bathroom remodeling cost guide sets out every project size.

Why a Condo Bathroom Renovation Is Different

In a house, a leak is your problem. In a condo, a leak is your problem, your neighbour’s problem, and a claim the corporation’s insurer gets involved in. That is the reason boards regulate bathroom work more tightly than any other room. The pipes behind your tile serve the units above and below, the waste stack is shared, and a waterproofing mistake on the eighth floor shows up on the seventh.

The second difference is the rulebook. Every corporation has a declaration, by-laws, and rules that define where your unit stops and the common elements start. Read those before you price anything, because they decide what you can change on your own and what needs the board.

Board Approval, Step by Step

1. Read the declaration and rules

Painting, flooring, cabinets, and fixtures replaced in place are generally allowed without permission. Walls, vents, and pipes are usually common elements, and touching them is where approval begins. Your property manager can point you to the exact clauses.

2. Submit a written application

Boards want the scope of work, drawings, materials, a timeline, your contractor’s credentials, and proof of liability insurance, commonly in the $2 million to $5 million range. Many also hold a refundable damage deposit. The more complete the package, the faster the review.

3. Get the board’s resolution before any work

Under Section 98, the board must approve an alteration to common elements by resolution before the change is made. Boards have broad discretion and are not obliged to say yes, but they must act reasonably. Do not book demolition until the resolution is in hand.

4. Sign the alteration agreement

Once approved, you and the corporation sign a Section 98 agreement that is registered on title. It sets out who repairs, maintains, and insures the altered elements, and it binds future owners of the unit. The owner normally pays to prepare and register it, plus any engineer’s review the board requests.

5. Pull the City permit and book access

Relocating plumbing still needs a City of Ottawa plumbing permit on top of the board’s approval. This is also when you book the service elevator, confirm working hours, and arrange how debris leaves the building.

Access Rules That Shape the Job

Approval gets you permission. Access decides how long the job takes. Most buildings restrict noisy work to weekday daytime hours, require the service elevator to be booked and padded, and expect hallways protected from the moment the first tool arrives. Debris leaves the building the way management specifies, never down the chute.

Those rules add days, not weeks, when they are planned for. What causes real delays is an unbooked elevator, a delivery outside the window, or a neighbour complaint on the first morning. We schedule the whole job around the building’s calendar before the first demo day.

What You Can Change, and What You Cannot

Inside the unit, most cosmetic scope is yours: tile, vanity, toilet, a tub or shower surround in the same position, lighting, the exhaust fan, and finishes. A tub-to-shower conversion in the existing footprint is the most popular condo upgrade we do, because it transforms the room without touching the stack.

What needs the board is anything that moves or modifies a common element: relocating the toilet, shower, or sink, opening a wall between rooms, changing a vent, or altering the stack. Boards are strict here for good reason, since even shifting a sink a foot means cutting into a shared drain.

Waterproofing is the one item every board cares about, whether they ask or not. A leak into the unit below is your responsibility, so we treat the shower membrane and floor waterproofing as non-negotiable on every condo job.

What a Condo Bathroom Renovation Costs in Ottawa

Three things move the number: whether fixtures stay in place, the building’s access rules, and the finish level. Here are our approved 2026 prices for the scopes a condo bathroom usually falls into.

The deposit is not a cost if the job is done cleanly; it comes back after management inspects. What adds real cost is relocating plumbing, which brings the permit, the agreement, and often an engineer’s review. Our full cost guide lays out every size, and a bathroom remodel in a house is a useful comparison.

Frequently Asked Questions

Do I need condo board approval to renovate my bathroom?

Cosmetic work with fixtures kept in place usually does not. Anything that touches a common element, such as moving plumbing, opening a wall, or changing a vent, needs board approval by resolution before work starts, under Section 98 of the Condominium Act.

What is a Section 98 agreement?

An owner’s alteration agreement between you and the corporation, registered on title. It sets out who repairs, maintains, and insures the change, and it binds future owners of the unit. The owner normally pays to prepare and register it.

How long does board approval take?

It depends on the board’s meeting schedule. A complete application with drawings, insurance, and contractor details moves fastest. Plan for a few weeks and book the work only after the resolution is in hand.

Can I move the toilet or shower in a condo?

Only with board approval and a City of Ottawa plumbing permit, because it means cutting into the shared stack. Most condo bathrooms keep fixtures in place for that reason, and a tub-to-shower conversion in the same footprint is the common alternative.

What deposit will the board ask for?

It varies by corporation, commonly $1,000 to $10,000 CAD depending on scope. It is refundable after management inspects the finished work and confirms no damage to common areas.
