Answered by a licensed electrician
Can a house fail electrical inspection?
Quick answer
Yes. In Ontario, a house can effectively fail an electrical inspection when the inspector finds defects such as missing GFCI protection, open junction boxes, unsafe panel work, or unpermitted wiring. A private safety inspection in the GTA typically costs $250–$400; correction work is quoted in writing after the defects are identified.
Yes — a house can “fail” electrical inspection, but the practical word is usually defects. An ESA inspection, insurance inspection, buyer inspection, or electrician’s safety inspection may find items that must be corrected before a permit can be closed, a lender or insurer is satisfied, or a buyer is comfortable proceeding.
The wording matters because different inspections have different authority.
A private electrical inspection does not usually stamp the whole house “pass” or “fail.” It gives you a written list of unsafe, non-compliant, or suspect conditions. An ESA inspection tied to a notification is more formal: if the inspector finds defects, the notification stays open until the defects are repaired and accepted. In real estate, that defect list can affect closing dates, insurance conditions, holdbacks, or who pays for corrections.
If you need a house checked quickly, City Power Electrical Services can inspect, quote corrections, file ESA notifications where required, and coordinate reinspection; we are an Ontario Licensed Electrical Contractor, ECRA/ESA #7015314, based in North York and serving Toronto and the GTA.
A house “fails” when defects are serious enough that the inspection cannot be accepted
For homeowners, “fail” means the electrical condition is not acceptable as-is. It does not always mean the house is dangerous to occupy that minute, but it does mean something has to be fixed, verified, or opened up before the file can move forward.
Common situations include:
- A buyer’s electrician flags unsafe wiring before purchase.
- An insurer asks for electrical corrections before binding or renewing coverage.
- ESA finds defects after a renovation, panel change, basement finish, EV charger, hot tub, or other notified work.
- A homeowner discovers unpermitted work and needs it reviewed before selling.
- A renovation inspector will not accept the electrical rough-in or final condition.
A useful way to think about it:
| Inspection type | What “fail” usually means | What happens next |
|---|---|---|
| Private safety inspection | Defects or risks are listed in a report | Owner gets repairs quoted and completed |
| ESA inspection on a notification | ESA issues defects or does not accept the work | Licensed contractor corrects and requests follow-up |
| Real estate inspection | Electrical issues affect price, closing, or insurance | Buyer and seller negotiate responsibility |
| Insurance inspection | Insurer wants proof of remediation | Repairs and documentation are provided |
A comprehensive electrical safety inspection in the GTA is typically $250–$400. Correction work depends on what is found, so it should be quoted in writing after the inspection, not guessed over the phone.

The most common defects are protection, junction, panel, grounding, and unpermitted-work problems
The defects that stop an inspection are usually not cosmetic. They are issues that increase shock risk, fire risk, overheating risk, or make the installation impossible to verify.
We often see these categories in Toronto and GTA homes:
Missing GFCI or AFCI protection
GFCI protection is expected in shock-risk locations such as bathrooms, exterior receptacles, garages, and other wet or damp areas where the Ontario Electrical Safety Code requires it. If a bathroom receptacle, exterior plug, or unfinished basement outlet is not properly protected, it can be written up.
AFCI protection is different. It is intended to reduce fire risk from arcing faults, and it is commonly required on many new or altered dwelling receptacle circuits. Older wiring may not be judged the same way as brand-new work, but when circuits are added, extended, or substantially altered, the current rules matter. This is why “it was there before” does not always pass after a renovation.
Open junction boxes and buried splices
A junction box must have a cover, must remain accessible, and must contain proper connectors and splices. Open boxes in attics, basements, garage ceilings, furnace rooms, and above drop ceilings are frequent inspection defects.
A splice hidden behind drywall without an accessible box is more serious. It cannot be inspected, it can overheat unnoticed, and it usually has to be opened and corrected.
Double taps and unsafe panel conditions
A “double tap” means more than one conductor is landed under a breaker terminal or lug that is not rated for that use. Some equipment allows specific multi-wire terminations, but many common breakers do not. Inspectors also look for missing panel fillers, wrong breaker types, scorched bus bars, loose neutrals, mixed neutral and ground connections where not permitted, and circuits that are not properly identified.
If the panel is overloaded, obsolete, damaged, or too small for the home’s current loads, the correction can become a panel or service issue. A 100A-to-200A panel upgrade in the GTA is commonly in the $3,200–$4,500 range including the ESA permit and inspection. If the concern is capacity rather than a single defect, read what size electrical panel your house needs.
Grounding and bonding defects
Grounding and bonding problems can show up as missing bonding to metallic systems, poor grounding electrode connections, bootleg grounds, reversed polarity, or three-prong outlets installed on old two-wire circuits without proper protection and labelling. These defects matter because breakers and GFCIs may not operate as intended during a fault.
If grounding is the specific concern, see how to tell if your house is properly grounded.
Unpermitted or unfinished electrical work
A finished basement, kitchen renovation, garage feed, hot tub circuit, EV charger, or panel change can fail inspection if the work was done without the required ESA notification, or if walls are closed before rough-in can be checked. In some cases, parts of the installation must be exposed so the inspector can verify cable routing, box fill, conductor size, support, protection from damage, and device ratings.

The correction process is inspect, prioritize, repair, document, then coordinate reinspection
The fastest way through a failed electrical inspection is to treat the defect list like a project plan. Guessing, patching only visible items, or calling multiple trades without one accountable electrician usually slows the process down.
A clean correction process looks like this:
- Read the defect list line by line. ESA wording, insurance wording, and buyer-report wording are not the same. We translate each item into the actual repair required.
- Separate safety hazards from documentation issues. An open junction or unsafe panel termination is different from a missing label, but both may need to be cleared.
- Confirm whether an ESA notification is required. Repairing or replacing devices may be simple; adding circuits, changing panels, correcting concealed wiring, or altering service equipment usually triggers formal notification.
- Quote the correction work in writing. Defects can range from a few device replacements to rewiring sections of the house, so the price should follow the inspection, not precede it.
- Complete repairs using listed devices and correct methods. That may include GFCI/AFCI breakers, proper junction boxes and covers, approved connectors, panel fillers, bonding repairs, or replacement of damaged cable.
- Arrange reinspection where required. For ESA-notified work, the correction is not finished until the notification is accepted or the inspector is satisfied.
- Keep the paperwork. Buyers, insurers, condo boards, and future electricians may ask for the inspection report, ESA certificate/notification documentation, and paid repair invoice.
For real estate, timing matters. If the defect list arrives close to closing, the parties need to decide whether repairs happen before closing, whether a holdback is used, or whether the buyer accepts responsibility after closing. That is a legal and contractual issue, so your lawyer and realtor should be involved. Our role is to identify the electrical scope, quote the work, complete what is approved, and provide electrical documentation.

Some defects are minor, but others should be treated as urgent
Not every inspection defect is an emergency. A missing panel directory, blank cover, or incorrectly placed label may be straightforward. But some findings should be corrected promptly because they can worsen under normal use.
Treat these as urgent:
- Scorching, melting, or heat damage in the panel.
- Breakers or conductors that are loose, buzzing, or discoloured.
- Open live splices in accessible areas.
- Water entry at the panel, meter base, or exterior equipment.
- Repeated breaker tripping after a correction attempt.
- Aluminum wiring with improper copper connections.
- Knob-and-tube wiring that has been altered, buried in insulation, or tied into modern circuits.
- Extension cords or power bars being used as permanent wiring.
If an inspector identifies a condition that appears immediately dangerous, do not wait for a real estate deadline to deal with it. Shut off the affected circuit if you can do so safely and call a licensed electrical contractor. If there are signs of active arcing, smoke, burning smell, or heat at the panel, treat it as an emergency.
A house can recover from a failed inspection. The key is to get a clear defect list, avoid DIY corrections, use the ESA process where required, and make sure the final paperwork matches the repair. That is what buyers, insurers, and inspectors are usually looking for: not perfection, but verified correction by someone accountable.

People also ask
Who pays to fix electrical defects found before closing?
It depends on the purchase agreement and negotiation. The seller may repair defects before closing, the buyer may accept a credit or price adjustment, or funds may be held back by the lawyers. An electrician can price the correction work, but your realtor and lawyer should decide how that cost is handled contractually.
Can ESA fail old wiring that was legal when installed?
Existing wiring is not always judged as if it were installed today, but unsafe conditions, damaged equipment, altered circuits, missing required protection on new work, or unpermitted renovations can still be written up. Once you add, extend, or modify wiring, the current Ontario Electrical Safety Code requirements often apply to that work.
Do I need a licensed electrician to fix inspection defects?
For most defect corrections, yes. In Ontario, electrical contracting work must be done by a Licensed Electrical Contractor, with ESA notification where required. This is especially important for panel work, new circuits, concealed wiring, service equipment, and any correction that must be reinspected or documented for insurance or sale.
Can a house be sold with electrical defects?
A house can be sold with known electrical issues if they are disclosed and the buyer accepts the risk, but defects can affect financing, insurance, price, and closing conditions. Serious items such as unsafe panels, active knob-and-tube, unremediated aluminum wiring, or unpermitted renovations often need pricing or repair before the deal is comfortable.
