Building Permits

Building permits are required prior to commencing construction of new buildings, renovating existing buildings, and constructing certain structures on your property.

A building permit is formal approval from your municipality to construct, add to, or renovate a building on your property. Building permits allow a municipality to protect the interests of both individuals and the community as a whole. By reviewing and approving plans before any work is done, the municipality can ensure that buildings comply with the Ontario Building Code (which sets minimum standards for design and materials), the local zoning bylaw (which controls building location and height, parking and uses that are suitable to the area), and other health and safety regulations.

Under the Ontario Building Code Act, a building permit is required for the construction or installation of a new structure, or for the construction of an addition or alteration of any structure.  The following is a list of typical projects that require a permit:

  • New home - commercial - industrial - institutional - designated structures
  • Accessory buildings such as a shed, etc. separate from the existing home or building and over 10 square metres or 107 sq ft. If the accessory building is under 107 sq ft, a building permit is not required, but check with the Planning Division for height restrictions
  • Any addition to a structure, regardless of the size of the addition
  • Interior alterations to create new rooms in a basement/attic or converting a garage to living space
  • Any structural changes including interior partitions
  • Adding structural features such as decks, balconies, canopies, etc.
  • Repairs or renovations
  • A new entrance or new window opening
  • Adding new dormers
  • Raising the house to provide a full basement or first storey or to excavate the basement to provide a full basement
  • Enclosing a porch/roof over a sundeck
  • Constructing a retaining wall in excess of 3 feet 3 inches of exposed height
  • Installing a pool or hot tub
