Do I Need a Permit for the Landscaping upgrades in Durham Region?
Thinking of building a retaining wall, Upgrading your yard, or removing a tree? Before you begin, it’s important to know that many landscaping or structural projects do require permits — and the requirements differ depending on which municipality in Durham you’re in.
Oshawa Landscaping Permits
In Oshawa, most simple landscaping jobs—like planting flowers, laying sod, or putting in a small walkway—don’t require a permit.
But things change when your project gets more complex. If you’re planning to:
- Build a retaining wall over 1 metre high
- Re-grade your property
- Do work near the sidewalk or street
…then you’ll likely need a permit.
For example, anything that affects public property (like the boulevard or sidewalk) requires a Road Occupancy Permit. Structural features, such as tall retaining walls, may also need a Building Permit from the city.

Whitby Landscaping Permits
Whitby’s rules are similar to Oshawa’s. If you’re just doing basic yard upgrades, you probably don’t need any permits.
However, you will need approval for:
- Retaining walls
- Changes to grading
- Any construction in the boulevard (the space between your property and the street)
Also, Whitby has strict tree protection bylaws. If you plan to cut down or prune a significant or mature tree, it’s best to check with the city first. Large hardscaping features may require a Building Permit, and work near sidewalks or roads may require a Road Occupancy Permit.

Pickering Landscaping Permits
In Pickering, things can get a bit more complicated—especially if your property is close to natural features like ravines, wetlands, or streams.
These areas fall under the Toronto and Region Conservation Authority (TRCA), which has its own set of rules for landscaping projects involving:
- Grading or filling
- Retaining walls
- Excavation or construction
Even in more suburban neighborhood’s, you might still need a Building Permit for structural landscaping work and city approval for driveway or curb changes. If you’re not sure, it’s smart to contact Pickering’s Building Services department before starting.

Ajax Landscaping Permits
Ajax takes drainage and safety seriously. Like the other Durham municipalities, you’ll need a permit for retaining walls over one metre, structural landscaping, or anything that changes the natural flow of water on your lot. If you’re planning driveway extensions, curb cuts, or boulevard work, you’ll also need approval from the Town.

Landscaping Near Conservation Areas
Across the Durham Region, if your property is near a ravine, wetland, floodplain, or watercourse, you may need to get Conservation Authority approval before you begin any landscaping that involves:
- Retaining walls
- Excavation or fill
- Grading changes
The TRCA (or other local conservation authorities) review these kinds of projects to protect natural areas and manage flood risks.
