• The deck is not supporting a roof
• The deck complies with Oshawa's Zoning By-Law for location and setbacks

Permit requirements

• An owner's authorization form will be required if the applicant is not the property owner.
• Include a copy of the survey or site plan of your property showing dimensions and distances to your property lines for all buildings, structures and your new deck.
• Include drawn-to-scale plans showing how you are going to build your deck.
