Oakville Requirements
Why Oakville Requires a Grading Plan
The Town of Oakville requires a lot grading plan as part of virtually every building permit application involving site alteration. Oakville's Lot Grading and Drainage Control By-law (2009-080) sets strict standards for how stormwater must be managed on private property to protect adjacent lots, municipal infrastructure, and Lake Ontario tributaries including Sixteen Mile Creek and Bronte Creek.

FAQ
Frequently Asked Questions
Do I need a grading plan for a building permit in Oakville?
Yes. The Town of Oakville requires a lot grading plan stamped by a Professional Engineer for most building permit applications involving site alteration, including new homes, additions, pools, and accessory structures.
What is Oakville's Lot Grading and Drainage Control By-law?
By-law 2009-080 governs how stormwater must be managed on private property in Oakville. It sets minimum grade requirements, prohibits redirecting drainage onto neighbouring lots, and requires grading certificates after construction is complete.
Does Conservation Halton need to review my grading plan?
If your property is within Conservation Halton's regulated area — typically within 30 metres of a watercourse, wetland, or floodplain — a permit from Conservation Halton is required in addition to the Town of Oakville building permit.
How long does it take to get a grading plan approved in Oakville?
The Town of Oakville typically reviews grading plans within 10–15 business days as part of the building permit review. We prepare submission-ready drawings to minimise comment cycles and keep your project on schedule.
What is a lot grading certificate and when do I need one?
A lot grading certificate is a stamped P.Eng. letter confirming that the as-built grades on your property match the approved grading plan. The Town of Oakville requires it before releasing the final occupancy permit.
Can you handle grading plans for properties near Sixteen Mile Creek or Bronte Creek?
Yes. We regularly work on properties within Conservation Halton's regulated areas along Sixteen Mile Creek, Bronte Creek, and their tributaries, coordinating both the Town of Oakville and Conservation Halton submissions.
