Decks
A guide for your deck construction project.
Decks greater than 10 square metres in area and higher than 61 centimetres above the adjacent grade require a building permit. Any size deck attached to a house requires a building permit.
Project preparation
Verify that your plans, proposed dimensions and location are permitted under the Town of Oakville's zoning by-laws which regulate the use, shape and location of buildings on properties.
To learn more visit our Zoning page or contact us at 905-845-6601 ext. 3955.
You will require a separate zoning certificate of occupancy approval. Apply online at online services.
Heritage properties are managed to conserve important cultural heritage attributes. If your property is on the town's heritage registry it may require heritage approval.
Learn more on our Heritage Properties page or contact a town Heritage Planner for assistance at 905-845-6601 ext . 3870 or 3875.
Trees on your property, your neighbor's property and on the municipal right of way may require tree protection, particularly when heavy equipment and excavation is involved. In certain instances, a permit may be required to remove private trees. Learn more about tree removal and how to find a licensed arborist.
If your project includes excavation and your property backs onto green space, a river bed or wetland you will need Conservation Halton approval. Learn more at Conservation Halton. Contact Conservation Halton for approval at web@hrca.on.ca or 905-336-1158.
To add a deck to your property you will need a building permit.
