Building a deck

A building permit is required to build a new deck, repair existing structural members and to rebuild an existing deck and/or stairs. In the following circumstances a permit is not required:

  • the deck is not part of the principle entrance into your dwelling;
  • the deck is not more than two feet above grade within four feet of the edge of the deck;
  • the deck is not covered with a roof;
  • the deck is not attached to the dwelling; and,
  • where an existing deck (previously approved under a building permit) requires only minor, non-structural repairs.

Restrictive covenants (registered on title), watercourse and riparian setbacks, utility rights-of-way, and distances to property lines may affect the location of your deck, whether a building permit is required or not. Determining if any of these factors will affect the location of your deck is the responsibility of the homeowner.
