So why do I need a building permit?

Well, maybe you don’t.  There are lots of things that can be done without the necessity of a building permit.  For example:

  • If you are building a small garden shed on your property, and the area of the shed is 10 square meters or less, you won’t need a permit.
  • What about building a deck and if it is less than 600mm off the ground? In some municipal jurisdictions, you won’t need a building permit.
  • The windows are really old and you want to replace the windows, what then?  Again, no building permit is required as this is considered to be building maintenance.  Same thing for replacing a door.
  • No permit is required to re-roofing with shingles or painting, or for new floor finishes.
  • Replacing the siding on a house would normally not require a permit unless the material used was heavy enough to require additional support.  For example, replacing vinyl siding with brick veneer would require a building permit.  In some cases, the brick, or stone veneer is very thin and requires no additional support.  No building permit is required.

However, here is when a permit may be required:

  • Any change to plumbing where a fixture is being added would require a permit.
  • The addition of a fuel-burning appliance such as a wood stove or built-in space heater or fireplace would require a permit.
  • Any change to a building where walls are being removed or relocated would require a permit.
  • Any building that is greater than 10 square metres, including a building that has no walls but has a roof, would require a permit.
  • A new fence may require a building permit if the fence is required because of a bylaw.
  • For example here is a link to fence information in Toronto
  • Here is a link for fence information in the Town of Whitby:

Here is when a building permit is required according to the Ontario Building Code, which governs all municipalities in the Province of Ontario:

8.(1) No person shall construct or demolish a building or cause a building to be constructed or demolished unless a permit has been issued therefor by the chief building official. 1992, c. 23, s. 8(1); 1997, c. 30, Sched. B, s. 7(1).

This includes renovations that require a change to a building that is not considered maintenance.  It should be noted that complete drawings must be included in the application for a building permit, and once the permit has been approved and issued, the construction must be in accordance to the approved drawings.  No changes are permitted without permission of the Chief Building Official (the head of the building department of each municipality.)

8.(13) No person shall construct or demolish a building or cause a building to be constructed or demolished except in accordance with the plans, specifications, documents and any other information on the basis of which a permit was issued or any changes to them authorized by the chief building official. 1992, c. 23, s. 8(13).
