Deck Permit

You may have to apply for a permit for your deck depending on its height above grade and whether it’s built as covered or uncovered.

If your deck is 24 inches or greater from the ground, you’ll need a Building Permit, and once the deck is finished, a final inspection is required. You will need a building permit to construct a covered or enclosed deck regardless of height.

To apply for a Building Permit for your deck you will need:

You will also need 2 copies of a Real Property Report (RPR) or site plan.

You will need two copies of dimensioned construction drawings including:

You do not need a permit to replace deck boards, as long as they are the same size and material of the existing deck.

Covered and Enclosed Decks

Any covered or enclosed decks/any decks that are both covered and enclosed require a Development Permit and a Building Permit and applicable mechanical permits. Once the deck is complete a framing inspection is required after the roofing is installed.

You will also need two copies of a Real Property Report (RPR) or site plan.

You will need two copies of dimensioned construction drawings including:

  • Elevations
  • Plan view
  • Cross section

You will need engineered components to include engineer-stamped drawings.

Here are some things to keep in mind when designing your deck:

  • Your deck may be built to the minimum side yard requirement of the property zoning. Example: an R1 zoning may be as close as 1.5 metres from the side property line or a R1N may be 1.25 metres from the side property line.
  • Your deck may be built a minimum of 4.5 metres from the rear property line.
  • A deck on a semi-detached residence may be built on the common property line. A solid fire rated privacy wall, between 2.0m (min) - 3.0m (max) in height, extending the full depth of the deck is required.
  • If the deck is to be enclosed, i.e. sunroom or screening, it needs to be built a minimum of 1.5 metres from the side property line and 7.5 metres from the rear property line.

Once your permit is ready to go, you’ll need to start your development within 90 days of the permit being issued.
