Do I need a licensed electrician to wire my garage in New Brunswick?

Yes, all electrical work in a garage in New Brunswick must be performed by a licensed electrician. This is a provincial requirement, not optional guidance. NB requires that electrical installations, modifications, and repairs be done by electricians holding a valid licence, and all work must be covered by an electrical permit with a subsequent inspection by the authority having jurisdiction.

This requirement applies to every type of garage electrical work — wiring a brand-new garage, adding circuits to an existing garage, installing a sub-panel, running an underground feeder to a detached garage, adding 240V outlets for tools or an EV charger, upgrading lighting, and installing garage door opener circuits. There is no exemption for homeowners in New Brunswick the way some other provinces allow limited homeowner electrical work. Even seemingly simple tasks like adding a new receptacle or replacing a light fixture with a different type require a licensed electrician if new wiring, circuit modifications, or panel work is involved.

The reasons for this requirement are rooted in safety, and garage electrical carries specific risks. Garages contain flammable vapours from gasoline, solvents, and other chemicals. The Canadian Electrical Code (CEC) has specific rules about receptacle heights, fixture types, and circuit protection in spaces where flammable vapours may be present. Garages also experience temperature extremes and moisture — in New Brunswick, a garage interior can swing from -25 degrees Celsius in January to +35 degrees in July, with condensation forming on cold surfaces when warm, moist air enters the space. Electrical connections that are not properly made can loosen with thermal cycling, creating arcing hazards. GFCI protection is required for all garage receptacles because concrete floors and damp conditions increase the risk of electrical shock.

What happens if you do electrical work without a licensed electrician? First, the work is not inspected, which means code violations may go undetected. Common DIY electrical mistakes in garages include undersized wire for the load, missing GFCI protection, improper bonding of the sub-panel, no dedicated circuit for high-draw equipment, and incorrect burial depth for underground feeds. Second, unpermitted electrical work creates problems when you sell your home — a home inspection will flag the work, and the buyer or their lender may require it to be brought up to code before closing. Third, if an electrical fire or injury results from unlicensed work, your homeowner's insurance may deny the claim. The cost of hiring a licensed electrician is modest compared to the potential consequences of unpermitted work.

What does a licensed electrician cost for garage work in NB? Basic garage wiring — a few circuits, lighting, receptacles, and a door opener circuit — runs $1,000 to $2,500 for an attached garage. A detached garage with an underground feeder, sub-panel, and workshop-level wiring runs $3,000 to $8,000 depending on complexity and distance from the house. These costs include the electrical permit and inspection. NB electrician rates generally fall between $75 and $120 per hour, though most garage electrical jobs are quoted as flat-rate projects.

You can reduce costs by doing the non-electrical preparation work yourself. Digging the trench for an underground feeder (after calling for utility locates), drilling holes through framing for wire runs, mounting electrical boxes on studs before drywall, and installing light fixture brackets are all tasks a homeowner can handle to reduce the electrician's on-site time. Discuss this with your electrician upfront — most appreciate the help as long as the prep work meets their standards.
