Should my NB renovation include a code-update inspection?
Should my NB renovation include a code-update inspection?
Yes — if you're doing any significant renovation in New Brunswick, a code-update inspection is strongly worth considering, and in many cases it's legally required.
When you pull a TSANB permit for renovation work, the electrical inspector will evaluate the work being done against the current Canadian Electrical Code as adopted in New Brunswick. This isn't optional — it's part of the permit and inspection process. But beyond the mandatory inspection on new work, many homeowners ask whether they should proactively bring existing electrical up to current code during a renovation. The short answer is: it depends on the scope of your project, but it's almost always a smart idea.
Why renovations are the right time to address code compliance
When walls are open and circuits are exposed, upgrading older wiring is far less expensive than doing it later. If your home has knob and tube wiring, aluminum wiring, or an older Federal Pacific or Zinsco panel, your renovation is the ideal window to address these issues. Knob and tube wiring covered by insulation is a recognized fire hazard, and many New Brunswick insurance companies will either refuse coverage or significantly increase premiums if it's present. Aluminum wiring on 15A and 20A branch circuits requires either replacement or proper remediation with CO/ALR-rated devices — something a licensed electrician can assess during your renovation.
What TSANB requires during renovation permits
Any new circuits, panel work, or wiring changes as part of your renovation will require a TSANB permit pulled by your licensed electrical contractor. The inspector will verify that all new work meets the current CEC. However, they may also flag pre-existing hazards they observe — particularly if your renovation opens up areas with older wiring. It's worth having a frank conversation with your electrician before work begins about what they're likely to find and what remediation might cost. TSANB can be reached directly at 1-800-999-0813 if you want to clarify what your specific project triggers.
NB-specific considerations to keep in mind
New Brunswick's Maritime climate adds some practical urgency here. Humidity, ice storm-related power fluctuations, and temperature swings put real stress on aging electrical systems. If your panel is undersized (under 100A service is common in older NB homes), a renovation is the right time to upgrade to 200A — especially if you're planning to add an EV charger or electric heat. A 100A to 200A panel upgrade typically runs $2,000–$3,500 in the New Brunswick market, and doing it alongside a renovation reduces disruption and can save on labour costs.
The bottom line on safety
Don't treat the inspection as a bureaucratic hurdle — treat it as a professional set of eyes on your home's electrical system. A TSANB inspection protects you legally, keeps your insurance valid, and most importantly, keeps your family safe. Skipping permits to avoid inspection is never worth the risk: unpermitted work can void your homeowner's insurance and create serious liability if you sell the home.
