How much does it cost to get a driveway widening permit from the City of Ottawa?

City of Ottawa Driveway Widening Permit Fees

If you want to widen your driveway in Ottawa, you will need a building permit from the City of Ottawa Building Code Services. As of 2025-2026, the permit application fee for residential driveway work typically ranges from $150 to $350, depending on the scope of work and whether the project triggers additional zoning reviews. If your widening also requires a new or modified curb cut, you will need a separate right-of-way permit from the City, which adds another $200 to $500 to your total permit costs.

Zoning Compliance Review

Before issuing a permit, the City checks your project against the Ottawa Zoning By-law (2008-250). The by-law limits how much of your front yard can be covered by hard surfaces — generally no more than 50% of the front yard area in most residential zones. In neighbourhoods like Barrhaven, Kanata, and Orleans where lots tend to be wider, homeowners usually have more room to work with. In older, narrower-lot areas like Centretown or the Glebe, hitting that 50% cap is much easier, which can limit how much you can actually widen.

Setback and Lot Coverage Rules

The zoning by-law also requires minimum side-yard setbacks. Your widened driveway typically cannot extend right up to your property line — a buffer of at least 0.6 metres is usually required. The City also factors in total lot coverage, meaning all impervious surfaces on your property (roof, patio, walkways, and driveway combined) cannot exceed the maximum permitted percentage for your zone. If your project pushes you over the limit, you may need to incorporate permeable pavers or a drainage solution to satisfy stormwater management requirements.

Additional Costs to Budget For

Beyond the permit fee itself, factor in $300 to $800 for a site plan or survey if the City requires one — this is common when the widening is significant or when your property is close to setback limits. If an inspection reveals issues with grading or drainage, you may need to hire an engineer for a grading plan, which runs $500 to $1,500. The actual construction cost for driveway widening in Ottawa ranges from $15 to $40 per square foot depending on material (asphalt, concrete, or interlock), so a typical 100-square-foot widening project runs $1,500 to $4,000 for construction alone.

Timeline Expectations

Permit processing in Ottawa generally takes 10 to 20 business days for straightforward residential driveway projects. During the busy spring season — when most Ottawa homeowners are booking work after the freeze-thaw cycle ends — processing can stretch longer. Submit your application by late winter to have permits in hand before the paving season kicks off in May.
