When was the last time you thought about your home’s electrical system? For many homeowners, it’s out of sight and out of mind, until something goes wrong. But regular home electrical inspections are essential for safety, efficiency, and peace of mind.

So, how often should you do an electrical inspection at home? The answer depends on your home’s age, usage, and any recent changes. Let’s explore when and why you should schedule an inspection, what’s involved, and how to stay ahead of potential hazards.

 

Why Electrical Inspections Matter?

Your electrical system powers everything in your home—from your fridge to your furnace to your phone charger. Like any system, it wears down over time. Wires degrade, circuit breakers weaken, and older systems may no longer meet safety standards.

Here are a few signs that something might be wrong:

  • Flickering lights or frequent breaker trips

  • Burning smells or discolored outlets

  • Buzzing sounds behind walls

  • Warm or sparking outlets

Regular inspections catch these issues before they become dangerous or costly.

 

When Should You Schedule an Electrical Inspection, and Why?

Even if things seem fine, timing matters. Here’s when you should be proactive:

1. Every 3 to 5 Years

Routine inspections catch wear and tear, and they ensure your system still meets current code requirements.

Why: Prevents dangerous conditions and ensures compliance.

2. Before Buying or Selling a Home

Inspections protect buyers from surprises and help sellers provide transparency and confidence to potential buyers.

Why: Identify problems early, avoid delays, and boost market value.

3. After Renovations or Additions

Whether it’s a basement reno or a kitchen upgrade, increased load or new circuits require verification.

Why: Make sure additions don’t strain your existing system.

4. Homes Over 40 Years Old

Older systems often can’t handle today’s demands and may not meet modern safety codes.

Why: Aging infrastructure increases fire risk and insurance challenges.

5. After Severe Weather Events

Storms, floods, or lightning can cause hidden electrical damage.

Why: Detect issues early, especially after water or surge exposure.

6. For Insurance or ESA Compliance

Insurers and local authorities may require a recent inspection to issue or renew policies.

Why: Ensure continued coverage and legal safety standards.

 

The ESA Inspection Checklist: What’s Included?

A licensed electrician typically uses a detailed ESA inspection checklist, which may include:

  • Electrical panel and service size evaluation

  • Grounding and bonding system checks

  • Testing of outlets, switches, and fixtures

  • Verifying smoke and carbon monoxide detector placements

  • Reviewing outdoor electrical systems and GFCI outlets

  • Ensuring recent work complies with Ontario’s Electrical Safety Code

The goal? To ensure your entire system is code-compliant, efficient, and safe.

 

Life Events That Trigger the Need for an Inspection

Beyond regular intervals, these life changes also warrant an inspection:

  • Purchasing or selling a property

  • Installing a new HVAC, EV charger, or generator

  • Rewiring a basement or kitchen

  • Switching insurance providers

  • Planning to rent out your home or basement unit

Each of these changes can significantly affect your electrical system and should be reviewed by a licensed professional.

Signs You Shouldn’t Ignore

Some issues can’t wait. If you notice any of these signs, call a licensed electrician right away:

  • Frequent breaker trips

  • Sparking outlets or switches

  • Tingling sensation when touching appliances

  • Outlets that emit heat or smell burnt

  • Lights dimming or flickering when other appliances are turned on

These are all red flags that your electrical system is under stress, and at risk of failure.

Prioritize Your Home’s Electrical Safety

Electrical safety isn’t something to manage after the fact—it’s a habit of smart homeowners who want to protect their property and loved ones. Whether you’re living in a sleek downtown condo or a decades-old bungalow, regular inspections aren’t optional, they’re essential.

So, how often should you do an electrical inspection at home?

Every 3 to 5 years is a good rule of thumb. But if your home is older, undergoing renovations, or showing signs of electrical stress, sooner is better.
