Can a homeowner do their own electrical work in New Brunswick?
Homeowner Electrical Work Rules in New Brunswick
This is one of the most commonly asked questions, and the answer in New Brunswick is more nuanced than a simple yes or no.
What the Law Says
New Brunswick's Electrical Installation and Inspection Act governs who can perform electrical work. In general, electrical work in NB must be performed by or under the supervision of a licensed electrician. However, there are limited exceptions for homeowners.
What Homeowners CAN Typically Do
Homeowners in New Brunswick can generally perform basic maintenance and like-for-like replacements in their own home:
- Replace light fixtures — swapping an existing fixture for a new one in the same location
- Replace switches and outlets — including upgrading to GFCI outlets or smart switches
- Replace a light bulb or ballast — basic maintenance
- Replace a plug on an appliance cord — repair work
- Install low-voltage systems — doorbells, thermostats (low-voltage only), landscape lighting transformers, ethernet/cable wiring
What Homeowners CANNOT Do
Work that modifies your home's electrical system requires a TSANB permit and must be done by a licensed electrician:
- Adding new circuits to your panel
- Running new wiring behind walls, through attics, or under floors
- Adding new outlets or switches in locations where none existed
- Panel upgrades or replacements
- Service entrance work (meter base, mast, main disconnect)
- Wiring a new addition, garage, or outbuilding
- Electric vehicle charger installation (new dedicated circuit)
- Hot tub or pool wiring
- Anything involving 240V circuits
- Generator transfer switch installation
The Permit Question
Even if a homeowner were technically capable of doing more advanced work, TSANB requires permits for anything beyond basic maintenance, and permits are tied to licensed electrical contractors. You cannot pull an electrical permit as a homeowner in New Brunswick the way you might in some US states.
This means: even if you know how to wire an outlet, if it involves new wiring, you need a licensed electrician to do the work (or supervise), pull the permit, and have it inspected.
Why This Matters
Insurance: If unpermitted electrical work causes a fire or injury, your homeowner's insurance can deny the claim. Insurance companies in NB routinely investigate the cause of electrical fires, and unpermitted work is a red flag.
Selling your home: When you sell, a home inspection will note any obvious amateur electrical work. Buyers (and their banks) may require a licensed electrician to inspect and certify the electrical system. Unpermitted work can delay or kill a sale.
Safety: The CEC exists because electricity is unforgiving. Improper wiring causes fires, shocks, and deaths. What seems like a simple outlet installation involves understanding circuit capacity, wire gauge, box fill calculations, and proper connections — details that trained electricians learn over a 4-year apprenticeship.
Cost of Hiring vs. DIY Risk
The financial argument for DIY electrical often doesn't hold up:
| Task | Licensed Electrician Cost | Risk of DIY |
|------|--------------------------|-------------|
| Replace outlet with GFCI | $100–$175 | Low (homeowner-legal) |
| Add new outlet (new wiring) | $200–$400 | Insurance void, permit violation |
| Install ceiling fan (existing box) | $150–$250 | Low (homeowner-legal) |
| Run new circuit for shop | $300–$600 | Insurance void, permit violation |
| Panel upgrade | $2,500–$4,500 | Illegal, extremely dangerous |
The Smart Approach
Do the tasks that are legal and within your comfort level — fixture swaps, outlet upgrades, switch replacements. For anything involving new wiring, new circuits, or panel work, hire a TSANB-licensed electrician. The cost is modest, the work is guaranteed, and your insurance stays valid.
Many electricians in Moncton, Saint John, Fredericton, and across NB are happy to handle small jobs. Some offer handyman-style service calls where they'll do several small tasks in one visit for a flat fee of $200–$400, which is the most cost-effective way to knock out a list of minor electrical improvements.
