Do I need a permit for a bathroom renovation in Moncton NB?

Whether you need a permit for a bathroom renovation in Moncton depends entirely on what work is being done — cosmetic updates like replacing a vanity, toilet, or fixtures on existing plumbing do not require a permit, but any new plumbing rough-in, electrical circuit work, or structural changes absolutely do, and these are inspected by both the City of Moncton and TSANB. Getting this distinction right protects your investment, your insurance coverage, and your ability to sell the home without problems.

In Moncton, building permits for structural modifications are issued by the City of Moncton Building Inspection Department. If your bathroom renovation involves removing or altering any wall — particularly if there's any question about it being load-bearing — a building permit is required and a site inspection will be conducted at the structural stage. Moncton's building inspection office can be reached directly to confirm permit requirements for your specific scope; most permit questions get a clear answer over the phone without requiring a formal application.

TSANB (Technical Safety Authority of New Brunswick) has jurisdiction over all electrical and plumbing work in the province, regardless of whether it's in Moncton, rural NB, or anywhere in between. This is where most bathroom renovation permits are actually required. TSANB licensed plumbers and electricians pull their own permits through TSANB and coordinate inspections — this is their responsibility, not the homeowner's, when you hire a licensed trade. But as the homeowner, you should confirm that your contractor is pulling the required permits and scheduling inspections, not assuming they are.

Specifically for a Moncton bathroom renovation, a plumbing permit is required for: any new drain rough-in, relocating an existing drain or supply line, adding a fixture where none existed (adding a second sink, adding a shower where there was none), rough-in for a new bathroom, or replacing the bathtub where the drain changes. Swapping a toilet, replacing a vanity faucet, or connecting a new vanity to the existing supply and drain stub-outs does not require a plumbing permit.

An electrical permit is required for: any new electrical circuit (such as adding a dedicated circuit for a towel warmer, in-floor heating, or a separate circuit for a steam shower), relocating outlets, installing GFCI protection where it didn't previously exist (though GFCI receptacles and breakers are mandatory within 1.5 metres of water sources under NB electrical code), adding a new exhaust fan circuit, or upgrading panel capacity. Replacing a light fixture on an existing circuit or swapping an exhaust fan for an identical unit on the same wiring typically does not require a permit, though the new fan must still meet current code requirements for ventilation capacity.

A practical example for a standard Moncton bathroom renovation: if you are replacing the tub surround tile, installing a new tub, replacing the vanity and toilet, and adding recessed lighting — but the drain stays in the same location, the plumbing rough-in doesn't move, and you're adding lights on existing circuits — you are likely in cosmetic update territory with no permit required. If you're converting a tub to a walk-in tile shower with a new linear drain location and adding new circuit capacity for in-floor heating, both a plumbing permit and an electrical permit are required.

The serious risk of skipping required permits in Moncton is not primarily the fine (though Moncton does enforce permit requirements). The real risk is that unpermitted electrical and plumbing work is not inspected, meaning errors that create fire or flood risk go undetected. When you sell your home, a real estate lawyer or home inspector may identify unpermitted work — requiring either tear-out for inspection or a significant price reduction. Home insurance policies in NB routinely exclude claims resulting from work that required a permit but didn't have one.

Always ask your renovation contractor directly: "What permits are you pulling for this project, and who is scheduling the inspections?" A licensed, reputable contractor will answer this question without hesitation. If a contractor suggests skipping the permit to save money or time, that is a significant red flag about how they operate generally.
