Garage, Shed & Accessory Structure Permit Drawings
Detached garages, sheds, and other accessory structures often need a building permit depending on their size and placement on your lot — a requirement homeowners frequently underestimate. U2E prepares the site plans, structural drawings, and permit documentation for accessory buildings across Ontario, so the project stays compliant from the start.
Which Accessory Structures Typically Need a Permit
Most municipalities exempt very small sheds from permit requirements, but the size threshold varies from one city to the next, and detached garages, workshops, and larger outbuildings generally do require a permit regardless of size. We confirm your specific municipality's threshold before assuming a structure is exempt.
Structures intended for anything beyond storage or vehicle parking — a workshop with electrical service, for example — often face additional scrutiny, since the intended use can affect which code requirements apply.
Placement, Setbacks & Lot Coverage
Where an accessory structure sits on the lot matters as much as its size. Municipal zoning bylaws typically set minimum setback distances from rear and side property lines, and may limit how close an accessory building can be to the main house or to other structures on the lot.
Accessory structures also count toward a property's total lot coverage in most municipalities, which can be a limiting factor on smaller urban lots. We check this during the site plan stage so placement doesn't become a problem after drawings are finalized.
Structural Drawings for Garages & Outbuildings
For a detached garage or larger accessory building, we prepare foundation plans, framing drawings, and exterior elevations sized to the structure's dimensions and intended use — whether that's vehicle storage, a workshop, or general storage space.
Our Process
We review your lot, confirm placement against zoning setbacks and lot coverage limits, and prepare the site and structural drawings for your building department. Once the application package is ready, we submit it and manage the file through to permit issuance.
