Permits for Light Fixture and Ceiling Fan Replacement in New Brunswick
This is one of the most frequently asked electrical questions, and the good news is that most fixture replacements don't require a permit. Here's the clear breakdown.
No Permit Needed
You do NOT need a TSANB electrical permit for:
- Replacing a light fixture with another light fixture in the same location, using the same wiring and electrical box
- Replacing a ceiling fan with a new ceiling fan in the same location (assuming the existing box is fan-rated)
- Swapping a light fixture for a ceiling fan IF the existing electrical box is fan-rated (see below)
- Replacing light switches — including upgrading to dimmers or smart switches
- Replacing receptacles — including upgrading to GFCI or tamper-resistant outlets
- Changing light bulbs or ballasts
Permit Required
You DO need a TSANB electrical permit for:
- Adding a new light fixture where none existed — requires running new wiring and installing a new electrical box
- Moving a light fixture to a new location — involves new wiring, even if you're eliminating the old location
- Adding a new circuit for additional lighting
- Running new wire through walls, attics, or ceilings
- Installing recessed pot lights where none existed (new wiring, new boxes, new circuit potentially)
- Adding an exhaust fan where there wasn't one (requires new wiring and possibly ductwork)
The Ceiling Fan Box Issue
This is the most common gotcha with ceiling fan installation. Standard light fixture electrical boxes are rated for the static weight of a fixture (typically up to 23 kg / 50 lbs). Ceiling fans create dynamic loads — the rotating blades generate forces that a standard box isn't designed to handle.
Fan-rated boxes are reinforced and anchored to the ceiling joists to handle the vibration and torque of a spinning fan. They're labelled "Suitable for Fan Support" or "Fan Rated" on the box.
If your existing box is NOT fan-rated and you want to install a ceiling fan:
- The box must be replaced with a fan-rated box
- If the existing box is accessible from above (attic), this is a straightforward swap: $100–$250 by an electrician
- If there's no attic access (finished floor above), a retrofit fan brace ($20–$40 for the hardware) can be installed through the existing hole. An electrician charges $150–$300 for this.
- No TSANB permit is typically required for replacing the box, as you're not running new wiring
DIY vs. Hiring an Electrician
DIY-appropriate (if you're comfortable):
- Replacing a light fixture: turn off breaker, verify power is off with a tester, disconnect old fixture, connect new fixture (match wire colours: black to black, white to white, ground to ground or green), mount, and test
- Replacing a switch or outlet
- Replacing a ceiling fan on an existing fan-rated box
Hire an electrician:
- Any fixture weighing more than 23 kg
- Ceiling fan installation where you're unsure about the box rating
- Any fixture in a high or awkward location (cathedral ceilings, stairwells)
- Adding new light locations or circuits
- If you encounter unexpected wiring (no ground, aluminum wiring, knob-and-tube)

| Work | DIY Cost | Electrician Cost |
|------|----------|------------------|

| Replace ceiling fan (fan-rated box exists) | $0–$50 | $150–$300 |
| Install ceiling fan (box upgrade needed) | Not recommended DIY | $200–$450 |
| Install new fixture (new location, new wiring) | Not legal DIY in NB | $250–$500 + permit |
| Install 6 recessed pot lights (new) | Not legal DIY in NB | $900–$1,800 + permit |
Fixture Selection Tips for NB Homes
Ceiling height: Many NB bungalows and split-levels have 7.5–8 foot ceilings. Flush-mount or low-profile fixtures are better than hanging pendants in these spaces. Ceiling fans need at least 7 feet of clearance from blade tips to floor (8 feet or more is ideal).
Damp/wet ratings: Fixtures in bathrooms (damp location), covered porches (damp), and open exterior locations (wet) must be rated accordingly. The rating is on the fixture's label.
LED compatibility: If replacing fixtures controlled by a dimmer switch, ensure both the new fixture/bulbs and the dimmer are LED-compatible. Mismatched dimmers cause flickering, buzzing, and shortened LED life. Replace old incandescent dimmers with LED-rated dimmers ($30–$60) during the fixture swap.
