What does the City of Ottawa inspection process look like for a new driveway installation?

City of Ottawa Driveway Inspection Process

When you pull a building permit for a new driveway in Ottawa, the City of Ottawa Building Code Services will require one or more inspections at different stages of the project. Understanding the inspection sequence helps you plan the work and avoid costly delays.

When Inspections Are Required

Not every driveway project triggers inspections. Simple resurfacing of an existing driveway within the same footprint usually does not require a permit or inspection. However, new driveway installations, driveway widenings, changes to grading or drainage, and new curb cuts all require permits and accompanying inspections. The permit document itself specifies which inspections are required for your particular project.

Stage 1: Pre-Pour or Pre-Pave Inspection (Subgrade)

For concrete and interlock driveways, the City typically requires an inspection after excavation and base preparation but before the final surface is installed. The inspector checks excavation depth, gravel base thickness and compaction, grading direction (water must flow away from the house and toward the road or a drainagge system), and setback distances from property lines. For Ottawa specifically, the inspector is looking for adequate base depth to handle the local frost line — which extends roughly 1.2 to 1.5 metres deep — though the full frost depth applies to foundations, not driveways. A properly prepared driveway base in Ottawa should be 200 to 300 millimetres of compacted granular material.

Stage 2: Curb Cut Inspection (If Applicable)

If your project includes a new or modified curb cut, the City's right-of-way inspector checks the curb cut separately. This inspection verifies the entrance width, the sidewalk crossing construction, and proper drainage from the driveway toward the road's storm system rather than onto neighbouring properties.

Stage 3: Final Inspection

After the driveway surface is installed, the City conducts a final inspection. The inspector verifies that the finished product matches the approved site plan, that grades and drainage function as designed, and that the driveway dimensions comply with the zoning by-law limits. For concrete driveways, the inspector may check that control joints are spaced appropriately (typically every 2.5 to 3 metres for Ottawa's climate, where freeze-thaw cycling is severe).

Booking and Timing

You (or your contractor) book inspections through the City of Ottawa's online permit portal or by phone. Inspections are typically available within 2 to 5 business days of booking. The contractor should not proceed to the next stage until the current inspection passes — pouring concrete over a base that has not been inspected means the inspector may require the work to be removed.

What Happens If You Fail

A failed inspection results in a deficiency notice listing what needs to be corrected. Common deficiencies include insufficient base compaction, improper grading, or drainage directed toward neighbouring properties. You correct the issues and rebook the inspection. There is no additional fee for re-inspection on the first attempt, but repeated failures may incur charges.
