- What Does NOT Require a Permit -

A building permit is not required for a detached accessory structure (gazebo, tool shed, etc.) that measures 15 square metres (161 square feet) in area or less and must not contain plumbing. When in doubt, contact the Chief Building Official and he will clarify whether you need a permit or not.

The following is a list of projects that do not require a permit*:

  • Installing asphalt shingles on a roof
  • Repointing of brick veneer
  • Damp proofing of basements
  • Replacing siding, without the addition of any exterior foam insulation
  • Replacing doors or windows (provided they are in the same size opening)
  • Kitchen or bathroom cabinets (not including plumbing)
  • New flooring
  • Installation of air conditioning units or heat pumps
  • Replacing existing forced-air furnace
  • Fences
  • Pool heaters
  • Painting and decorating
  • Landscaping
  • Earthen manure storage structure
  • Installation of solar collector systems having a face area less than 5 m²

* Note: Although a building permit may not be required, your project must still comply with the Ontario Building Code and any applicable law, such as the zoning by-law.
