Can my neighbour in Nepean block me from building a second driveway entrance on my corner lot?

Second Driveway Entrances on Corner Lots in Ottawa

Corner lots in Ottawa suburbs like Nepean, Barrhaven, Kanata, and Orleans are popular candidates for second driveway entrances because they have frontage on two streets. While your neighbour cannot directly block you from building a second entrance, the City of Ottawa's zoning by-law and permit process give neighbours formal opportunities to object — and the zoning rules for corner lots create significant hurdles on their own.

Zoning Rules for Corner Lot Driveways

The Ottawa Zoning By-law treats corner lots differently from interior lots. A corner lot has two street frontages — a "front" and an "exterior side" — and the by-law applies front yard and exterior side yard provisions to both. Driveway access from the exterior side yard is generally permitted, but the by-law imposes restrictions: the entrance must meet minimum setback distances from the intersection (typically 6 to 9 metres for safety sight lines), the total hard surface coverage in both yards cannot exceed the 50% limit, and the curb cut must be approved through the right-of-way permit process.

Sight-Line Triangle Requirements

Corner lots must maintain a clear sight-line triangle at the intersection — an unnobstructed area where drivers and pedestrians need to see each other. The City of Ottawa typically requires a triangular area extending 6 metres along both street frontages from the corner to be kept free of visual obstructions above 0.6 metres in height. A second driveway entrance that falls within or too close to this triangle will be denied.

The Neighbour's Role in the Process

Your neighbour cannot unilaterally stop your project, but the City's process includes mechanisms for neighbour input. If your second driveway requires a minor variance from the Committee of Adjustment (for example, because it does not meet the minimum setback from the intersection), affected neighbours are formally notified and can submit written objections or appear at the Committee hearing. A strong objection supported by valid planning concerns — such as traffic safety, parking loss, or drainage impacts — can influence the Committee's decision.

Common Grounds for Objection

Neighbours in Nepean and similar suburban areas most commonly object to second driveway entrances on the grounds of lost on-street parking (the curb cut eliminates one or more parking spaces), increased traffic on a quiet residential street, drainage concerns (more impervious surface can redirect water toward neighbouring properties), and reduced property values. The Committee of Adjustment weighs these objections against the planning merits of your proposal.

What If You Do Not Need a Variance

If your second driveway fully complies with the zoning by-law and does not require a variance, the process is simpler: you apply for a building permit and a curb cut permit, and the City reviews based on technical compliance. Neighbours are not formally notified for standard permit applications. However, a neighbour can still file a by-law complaint after construction if they believe the work violates any by-law provisions.

Practical Advice for Corner Lot Owners

Before applying, talk to your neighbours. A conversation upfront can prevent a formal objection later. Have a site plan prepared showing how the second entrance meets all setback, sight-line, and coverage requirements. If you need a variance, a well-prepared application with professional drawings and a traffic assessment significantly improves your chances.
