What are the rules for cleaning construction dust that reaches neighbouring properties in Ottawa?

Construction dust drifting onto neighbouring properties is a common source of friction during and after renovation projects in Ottawa. If dust, debris or residue from your project has landed on a neighbour's property, the practical and neighbourly response is to deal with it quickly. Neighbours can also raise complaints with the City, so it is better to handle it before it gets that far.

Responsibility for Construction Dust in Ottawa

If a neighbour says dust from your project damaged their car finish, outdoor furniture or the inside of their home, and you are unsure where you stand, get advice specific to your situation rather than relying on general rules — and remember that hiring a contractor does not necessarily take the issue off your plate. In practice, most of these situations are settled by talking to the neighbour and paying for a proper clean.

Prevention is far cheaper than cleanup. When you hire a post-construction cleaning company, ask how they control dust. Common methods include HEPA-filtered air scrubbers running inside the work area to capture airborne dust before it escapes, wet sweeping and misting to keep dust down at the source, and temporary barriers — plastic sheeting over windows, doors and openings — to keep dust inside the work zone. For exterior work, wetting surfaces before disturbing them reduces airborne dust considerably.

If dust has already reached a neighbour's property, offer to arrange and pay for cleaning of the affected areas. Exterior surfaces such as siding, windows and hardscaping usually need careful washing or detailed hand cleaning. Interior contamination — dust that came in through open windows or a ventilation system — is more involved and may include cleaning vents or ducts. Ask for itemized written quotes so you and your neighbour can see exactly what will be done, and agree on the scope before work starts.

Fine construction dust, such as concrete and drywall dust, can be stubborn on outdoor surfaces, so a quick rinse is not always enough; ask the cleaning company what method they will use on each surface.

The best practice is to talk to neighbours before construction begins, control dust during the project, and clean up promptly if any gets out.
