Does an Ottawa driveway resurface need a permit?

Routine driveway resurfacing (overlaying new asphalt over existing asphalt) typically does NOT require a permit from the City of Ottawa. However, any work that changes the driveway footprint, alters drainage patterns, or involves the municipal right-of-way does require a permit.

Standard resurfacing work that's permit-exempt includes placing a new layer of asphalt over an existing driveway within the same boundaries, sealcoating, crack repair, and pothole patching. The City of Ottawa considers this routine maintenance similar to roof replacement or exterior painting. Most residential asphalt overlays fall into this category — you're simply adding 40-50mm of new hot-mix asphalt over the existing surface to restore smoothness and weather protection.

You DO need a City of Ottawa permit (call 3-1-1 or apply online) when resurfacing involves widening the driveway, changing the curb cut or driveway opening onto the municipal road, altering the driveway apron (the section between sidewalk and road), or modifying drainage patterns that affect stormwater flow. Any work within the municipal right-of-way requires a permit and inspection. If your resurfacing project includes adding a parking pad, extending the driveway toward the street, or installing new drainage features like catch basins, permits are required.

Ottawa's extreme freeze-thaw climate makes the distinction between resurfacing and reconstruction critical. True resurfacing only works when the existing base is stable and the surface damage is limited to the top asphalt layer. If your driveway has base failure, major cracking, or drainage issues, an overlay will simply reflect those problems through the new surface within one or two winters. In Ottawa's climate, overlays over failed bases typically show reflective cracking by the following spring.

Before resurfacing without a permit, ensure your project stays within existing boundaries and doesn't alter drainage. The new surface must still slope at minimum 2% away from your house and toward the street or approved drainage area. If you're unsure whether your project requires a permit, a quick call to the City of Ottawa at 3-1-1 can provide clarification based on your specific situation.

Practical timing consideration: Even permit-exempt resurfacing should be scheduled during Ottawa's paving season (late May through September) when ambient temperatures consistently exceed 10°C. Hot-mix asphalt placed in cooler conditions won't compact properly and will fail prematurely in our harsh winters.
