Do I Need to Tell My Insurer If I'm Renovating Myself Without a Contractor?

Yes, in most cases you need to tell your insurer if you're doing your own work on electrical, plumbing, structural elements, or an addition to the house. Purely cosmetic work (painting, floating floors, cabinets) generally doesn't need to be reported, but check your policy to be sure. Failing to declare major work can get a future claim tied to that part of the house denied, even years later.

What's Happening?

Your home insurance policy is priced based on the information the insurer has about your house: its age, condition, who has done work on it. When you modify the electrical, plumbing, or structure yourself without reporting it, that information becomes inaccurate in the insurer's eyes, even if the work is done well.

The insurer usually doesn't find out right away. The problem surfaces at claim time: a water leak, an electrical fire, structural damage. If the investigation shows the cause is tied to undeclared work done without a licensed contractor, the insurer can reduce or fully deny the payout.

This isn't about punishing you for doing the work yourself — it's that the insurer assesses risk based on who did the work and whether it met code.

Is It Dangerous?

The risk here isn't physical, it's financial and legal. Notify your insurer promptly, before starting the work, if:

• you touch electrical wiring, even to add an outlet or a light fixture
• you modify plumbing (moving a drain, adding a bathroom)
• you remove or alter a wall, especially one that might be load-bearing
• you build an addition or increase the livable square footage
• the work requires a municipal permit you haven't obtained
• you hire a worker without an RBQ license for a regulated trade

Poorly done electrical or plumbing work can also cause real physical danger (fire, water damage) on top of the coverage risk — one more reason to go through a licensed professional for those specific parts, even if you do the rest yourself.

Most Common Causes

Why This Happens in Quebec

In Quebec, the Régie du bâtiment (RBQ) requires a license for most construction work, including electrical and plumbing, with limited exceptions for an owner-occupant working on their primary residence. Many homeowners assume they can do everything themselves simply because they own the house, when the rules actually vary by type of work.

Quebec municipalities also require permits for most structural renovations or additions, and a missing permit is exactly one of the first things an insurer checks during a claim tied to recent work.

How to Check It Yourself

• Pull out your insurance policy and read the section on renovations or declared modifications
• Call your broker or insurer before starting and ask precisely what needs to be declared
• Check with your municipality whether the planned work requires a permit
• Check whether the work touches electrical, plumbing, gas, or structure — these categories almost always require a declaration and often a licensed professional

Don't rely on what a neighbour or a hardware store employee told you about what's allowed — the rules vary by insurer, municipality, and type of work.

Can I Ignore It?

It depends on the type of work. For painting, a floating floor, or new cabinets, no, there's generally nothing to declare. For anything touching electrical, plumbing, structure, or the home's square footage, no, you cannot skip this step.

The risk isn't immediate — nothing happens the day you fail to declare it. The risk materializes at the worst possible time: during a claim, exactly when you need your insurance to work. A denied claim for water damage or a fire can represent tens of thousands of dollars left uncovered.

How Much Does It Cost?

For comparison, a full kitchen renovation costs between $15,000 and $50,000 — an amount you could end up absorbing yourself if an electrical fire tied to undeclared work destroyed the room.

When to Call a Professional

• Before starting, call your broker or insurer to find out exactly what needs to be declared
• Call an RBQ-licensed electrician for anything touching the panel, wiring, or new outlets
• Call a licensed plumber for anything touching water supply, drainage, or gas
• Call your municipality before removing a wall, adding onto the house, or altering the structure to find out if a permit is required

A licensed professional provides a compliance certificate your insurer can require during a claim — a document that fully DIY work cannot provide.
