Building Permits

When are Building Permits Required?

In general, a building permit is required to erect, install, extend, alter or repair a building. A building is defined as a structure occupying an area greater than 10 square metres (107 square feet).

The following are examples of projects which will require building permits:

	Construction of a new home.
	Addition of a carport, garage, porch or room to an existing home.
	Construction or finishing of rooms in the basement or attic.
	Any structural work including alterations to interior partitions or the installation of new skylights, windows or doors.
	Addition of a dormer.
	Enclosing a porch or deck.
	Addition of a deck to an existing home if it will be over 2ft. above the adjacent perimeter grade or if it is to be attached to the house.
	Raising a house to provide a full basement.
	Excavating a crawl space to construct a full basement.
	Constructing or installing accessory buildings such as a garage, tool shed, or playhouse larger than 107 sq. ft.
	Fireplaces and other heating appliances including the replacement of furnaces and ductwork.
	Removing and replacing insulation during remodelling or renovating

When are Plumbing Permits Required?

A Plumbing Permit is required for the installation of new drains, sewers and plumbing fixtures. However, if your project involves construction that requires a Building Permit, the plumbing approval will be included, and a separate Plumbing Permit is not necessary.

You do not require a plumbing permit to change existing fixtures but require a permit if you plan to change their location.

After your permit has been issued, you as the homeowner may install your own plumbing, drains and sewers. If, however, you are hiring a contractor ensure that they are licensed by the Town of Oakville for the work to be performed.

When do you require Electrical Permits?

Prior to the installation or alteration of electrical equipment, you are required to obtain an Electrical Permit from Electrical Safety Authority.

Note: These rules apply only to the Town of Oakville, please check the permitting requirements for your local municipality.

The Oakville Handyman's clients rarely require permits to complete their repair and maintenance projects but we encourage our clients to contact the Town of Oakville Building Department before starting any large project and discuss permitting requirements.
