Does Ottawa require permits for tile work that involves moving plumbing or electrical?

Yes, Ottawa requires permits when tile work involves moving plumbing or electrical connections — these are not optional. Any project that relocates, adds, or modifies plumbing (moving a shower drain, adding a new shower or tub, relocating a toilet rough-in) or involves electrical work (any heated floor system with wiring, for example) must have the appropriate permits before work begins.

Why this matters in Ottawa specifically: Our extreme climate means that plumbing and electrical failures are particularly costly. A missed permit on a plumbing relocation can result in an unpermitted installation that fails catastrophically during Ottawa's brutal winters, potentially exposing the house to water infiltration when it's -30 degrees outside. Similarly, an unpermitted electrical heated floor installation is a genuine fire hazard in a wet bathroom environment and will void your home insurance entirely. The City of Ottawa Building Code Services takes these seriously for good reason.

Here's what you actually need to know: Plumbing work requires a plumbing permit from the City of Ottawa and must be performed by a licensed plumber (the plumber typically pulls the permit). Electrical work — specifically any heated floor installation with wiring — requires an ESA (Electrical Safety Authority) electrical permit and must be completed by an ESA-licensed electrician. You cannot hire an unlicensed electrician and later have an ESA inspector approve the work; the electrician must be licensed before the work is done. The electrical permit process typically adds 2 to 4 weeks to the project timeline and costs roughly $150 to $300 depending on the scope.

Critical point: The ESA inspection is not optional, not a formality, and not something you can skip or work around. An unpermitted electrical installation in a bathroom heated floor voids your homeowner's insurance, creates genuine shock and fire hazards in a wet environment, and can be extremely expensive to remediate if discovered during a home sale or insurance claim. Any contractor who suggests doing electrical work "without pulling permits" is not someone you want working in your home.

To get started, contact the City of Ottawa Building Code Services (call 3-1-1 or visit ottawa.ca) to confirm current permit requirements for your specific project. Most straightforward tile installations without plumbing or electrical components — bathroom floor tile, a shower surround where the drain is not moving, kitchen backsplashes, floor tile in living areas — do not require permits and can proceed immediately.
