Can a home inspector check for unpermitted electrical?

Yes, home inspectors can identify signs of unpermitted electrical work, though they cannot definitively determine permit status without checking ESA records. Experienced inspectors look for telltale signs like mismatched components, code violations, or work that appears newer than the home's electrical system.

Home inspectors typically spot unpermitted work by identifying code violations and inconsistencies in the electrical system. They look for things like new circuits that don't match the existing installation style, outlets or panels that appear recently installed but don't meet current code requirements, or work that shows signs of being done by unqualified individuals. For example, they might notice new GFCI outlets in a kitchen that aren't properly wired, or a subpanel installation that lacks proper labeling or clearances required by the Ontario Electrical Safety Code.

However, inspectors cannot access ESA permit records during their inspection, so they can only flag suspicious work and recommend verification. The most reliable way to confirm permit status is to contact ESA directly at 1-877-ESA-SAFE or check their online permit database. As the homeowner, you can request permit history for your property, which will show all electrical work that was properly permitted and inspected.

Common signs inspectors flag as potentially unpermitted include Federal Pacific or Zinsco panels (often replaced without permits), new circuits added to old panels without proper documentation, aluminum wiring repairs that don't meet current standards, and EV charger installations that lack proper circuit protection. They also look for obvious DIY work like mismatched wire nuts, improper junction boxes, or circuits that don't follow logical routing patterns.

If unpermitted work is suspected, you'll need to address it before selling or for insurance purposes. ESA can require the work to be brought up to current code standards and properly inspected, which might mean redoing portions of the installation. This is why buying a home with suspected unpermitted electrical work should factor into your negotiation strategy.

For peace of mind during a home purchase, request that the seller provide documentation of any recent electrical work, including ESA permits and inspection certificates. If you're selling and discover unpermitted work, it's often better to address it proactively rather than have it discovered during the buyer's inspection, as this gives you more control over the solution and costs.
