Projects That Require a Building Permit

A building permit is a commitment to safety. The Ontario Building Code Act requires that you obtain a building permit before starting construction. By applying for a building permit, you ensure that your project meets building code, fire, health, and safety standards.

  • New buildings or structures greater than 10 square metres (108 ft²) in total floor area, measured by the outside dimensions, or any size if they include services. This includes sheds, sleeping cabins or other accessory buildings or structures, including sheds and shed packages purchased from a store.
  • Additions to existing buildings or structures.
  • Renovations
  • New or replacement decks.
  • Wood burning appliances, including new or replacement of existing components.
  • Replacement of windows or doors if the rough opening size is enlarged.
  • Relocation or addition of plumbing fixtures.
  • Replacement of interior water supply or drain pipes.
  • Solar panels on new or existing structures that did or would require a permit.
  • Permanent structure greenhouses.
  • Quonset huts and pre-engineered metal buildings.

What happens if I build without a permit?

As a property owner, it’s your responsibility to ensure that a building permit is obtained, even if you’re hiring a builder or contractor. If you’re unsure whether you need a permit, contact the Building Department to find out. The Building Bylaw and the Ontario Building Code Act have penalties of up to $50,000 upon conviction for illegal construction. We charge an additional $400 administration fee on permits if started without a permit. We also have a $1000 Provincial Offences Ticket for infractions.
