Can I finish my basement electrical myself or do I need a licensed electrician in New Brunswick?

In New Brunswick, you cannot legally do your own basement electrical work beyond the most basic tasks like replacing an existing outlet or light switch. Any new circuits, new outlets, new lighting fixtures on new circuits, or panel modifications require a TSANB permit — and TSANB permits can only be pulled by licensed electrical contractors.

This is a common question from homeowners looking to save money on a basement finish, and it's understandable — electrical work is one of the most expensive trades in a basement renovation. But New Brunswick's regulations are clear: the Canadian Electrical Code as enforced by TSANB requires that all new electrical installations be performed by a licensed electrician.

What you CAN do yourself in your New Brunswick basement: replace existing outlets and switches with new ones (same type, same location), replace existing light fixtures (same circuit, same location), install low-voltage wiring like ethernet cables, coax, and speaker wire, and paint around electrical boxes after the electrician has finished. Basically, if it doesn't involve opening the panel, running new wire, or creating new connection points, you can handle it.

What requires a licensed electrician includes all the heavy lifting of a basement finish: running new circuits from the panel, installing new outlets (code requires outlets every 12 feet along walls plus near any countertops), installing pot lights or other ceiling fixtures on new circuits, wiring bathroom exhaust fans, installing GFCI outlets in the bathroom and any unfinished utility areas, installing AFCI-protected circuits for bedroom and living areas (required by current code), and any 240V connections for a basement bathroom heater or sauna.

The cost for basement electrical in New Brunswick typically ranges from $3,000 to $8,000 depending on the size of the space and the number of circuits, outlets, and fixtures. A typical 800 square foot basement finish might need 4 to 6 new circuits, 15 to 25 outlets, 8 to 15 pot lights, bathroom fan and GFCI outlets, and smoke/CO detectors — which runs around $4,000 to $6,000 for the electrical portion.

Here's a money-saving tip that's perfectly legal. You can do all the non-electrical work yourself (framing, insulation, vapour barrier, drywall) and hire the electrician to come in at the right stage. The electrician does the rough-in after framing but before drywall, then comes back for the finish work (installing outlets, switches, fixtures) after drywall is complete. This way you're only paying the electrician for electrical work, not waiting around while you frame walls.

A TSANB inspection is required before drywall goes up (rough-in inspection) and again after everything is finished (final inspection). Your electrician will coordinate both inspections.
