Do I need a permit for electrical work during a renovation in New Brunswick?

Yes — virtually all electrical work beyond simple fixture swaps requires a permit and TSANB inspection in New Brunswick, and this work must be performed by a licensed electrician. This is provincial law, not a municipal preference, and it applies equally in Moncton, Fredericton, Saint John, and in rural communities across the province.

The Technical Safety Authority of New Brunswick (TSANB) regulates all electrical work in the province under the Electricity Act. Any work involving new wiring, new circuits, panel upgrades, additional outlets, new sub-panels, or changes to the electrical system requires a permit from TSANB and a subsequent inspection by a TSANB electrical inspector. The electrician pulls the permit — it's part of how licensed trades operate in NB — and schedules the rough-in inspection before walls are closed and the final inspection once the work is complete. You should never have to chase inspections on a properly run electrical project; your electrician handles this as a matter of course.

What doesn't require a permit? Simple fixture swaps on existing circuits — replacing a ceiling light fixture, swapping out a receptacle cover plate, changing a light switch — are generally considered maintenance work that a homeowner can perform (with the breaker off) without a permit. But the moment you're adding a new circuit, moving an outlet to a different location, or installing a dedicated circuit for a new appliance, you're into permit territory. In a kitchen renovation, for example, adding a dedicated 20-amp circuit for a new refrigerator, upgrading from a 100-amp to a 200-amp panel, and installing new pot lights on a new circuit all require permits and TSANB inspections.

Older NB homes — and the province has a substantial stock of homes built between 1930 and 1975 — frequently have electrical systems that reveal their age when renovation work starts. Knob-and-tube wiring is still present in many Fredericton, Saint John, and Moncton homes of that era. Some insurers in NB will not provide coverage, or will require endorsements and surcharges, for homes with active knob-and-tube wiring. A kitchen or basement renovation that opens walls often triggers a mandatory upgrade of the electrical in the work area — your electrician and building inspector can advise on what's required in your specific situation, but budget for it. A full electrical upgrade from knob-and-tube in an older NB home runs $8,000-$20,000 depending on the size of the home and the complexity of the existing system.

What TSANB Electrical Permits Cost and Cover

TSANB permit fees for residential electrical work are relatively modest — typically $80-$200 for standard renovation electrical work, with the permit fee rolled into your electrician's quote in most cases. The inspection confirms that wiring methods, box fill, circuit protection, grounding, and bonding all meet the Canadian Electrical Code (which NB adopts with provincial amendments). This isn't bureaucratic box-checking; the inspection protects your family from the real risk of electrical fire and electrocution from improperly installed wiring.

From a practical standpoint, the renovation sequencing matters. Electrical rough-in (running wires before drywall) must be inspected and approved before walls are closed. If you close drywall before the rough-in inspection and the inspector finds problems, the wall comes open — at your expense. Experienced renovation contractors in NB sequence the work correctly by default: rough framing, then rough mechanical (electrical, plumbing, HVAC), then inspections, then insulation and vapour barrier, then drywall. Skipping the inspection sequence creates expensive problems.
