To secure a building permit, you must meet all of the provisions outlined by The Town of Aurora Zoning Bylaws.
The by-laws indicate that uncovered decks, patios, and terraces should not exceed three metres above grade. Unless outlined in the zoning by-law, uncovered decks are subjected to a minimum distance separation of 4.5m from the front lot line, 3.8m from the rear line, and 3m from the exterior side lot line.
If the deck is permitted to sit closer than 1.2m to the side lot line, a privacy screen with a minimum height of 1.5m is required.
Any decks built under two feet above the finished grade do not require a permit.
