Garages and Sheds

Building permits are required for most accessory buildings including garden sheds, garages, gazebos, etc. that:

  1. Contain plumbing regardless of size,
  2. Exceed 10m2(107ft2) in area, or
  3. Are attached to another structure with a combined area that exceeds 10m2

A tent garage under 60m2 (645 ft2) which is not attached to another building does not require a building permit but must be at least 3.0 metres from another structure. Any accessory buildings that do not require a permit are still required to comply with the Town’s zoning by-laws and other applicable laws.


Make sure you can build the garage, shed or gazebo you want by consulting:

  • Town of Georgina, Zoning By-law:

    • How to use the Zoning By-law
    • Once you have reviewed the Zoning By-law, please email the Building Division for more Zoning By-law information. Note that accessory buildings are not permitted on residential lots where there is no main-use building such as a house.
  • Town of Georgina, Septic System Approvals:
    • If your property is serviced by a septic system, your accessory structure must be located away from your septic. Please email the Building Division regarding the location of your septic system.
  • Town of Georgina, Site Alteration and Entrance Permit
    • Contact the Development Engineering Division by email for information regarding a Site Alteration Permit and entrances. This ensures that the grading and drainage of your property will not negatively affect a neighbouring property. This approval will be needed before building permit issuance.
  • Lake Simcoe Region Conservation Authority:
    • Approval from the LSRCA is needed if you are constructing in its regulated area. LSRCA regulations may restrict construction. Consult LSRCA’s mapping tool to see if your property is regulated.
  • York Region
    • If you are moving or adding a driveway, obtain an Entrance (Road Use) permit from the Region for driveway access for properties on Regional Roads
  • Other approvals (where regulated)


Design is the next step. You will need a set of construction drawings to submit to the Building Division for review before a permit can be issued and construction can begin.

  • Design drawings

    • Must be prepared by a competent designer
    • Must be drawn to scale and accurately and neatly drawn
    • May be made by the owner if the owner takes responsibility for the design (Note: all designers must demonstrate a level of design competency)
    • May require a designer with specific credentials (ie. P.Eng.) for complicated or specialized designs
  • The drawing package will include:
    • Site Plans  (showing lot dimensions, north arrow, the road, any watercourses, all buildings, building sizes, dimensions of the proposed building(s), plus setbacks to property lines of all existing and proposed buildings) Note: A survey is a great starting point for a site plan as it will already have most of this information.
    • Foundation plans (The design must be prepared by a professional engineer if proposing a slab foundation over 55m2  (592 ft2), if over 55m2 and supporting masonry or if supporting more than one story). 
    • Floor plan showing window and door openings with header sizes
    • Cross section of construction from the foundation to the roof
    • Elevations
    • Roof framing plans (or Truss drawings with layout and P.Eng seal, where proposed)
    • Additional information where necessary to accurately show proposed work

When applying for a building permit we require:

Contact the Building Division by email to request more information or to clarify anything regarding construction of a building.

Make sure you've got it all with our Garage and Accessory Buildings Checklist.
