Garage & Accessory Structure Permit Drawings
The service is matched to the actual project, municipality and information available before detailed permit documentation is finalized.
What does this service need to solve?
Permit requirements depend on the type, size, attachment, use and services in the structure. Even where a small shed qualifies for a Building Code permit exemption, municipal zoning and other property rules can still apply.
Residential permit drawings should start with the actual house, property and proposed construction—not a generic floor plan. Zoning, existing conditions, site information and technical requirements can change what the municipality needs to review.
What changes the scope of Garage & Accessory Structure Permit Drawings?
The same project name can require different drawings and approvals on different properties. These four checks help define the real permit problem before the set is developed too far.
Existing conditions
Existing walls, foundations, stairs, openings, services and prior construction can affect the proposed design.
Property & zoning
Setbacks, lot coverage, height, permitted use and other zoning rules can define the feasible building envelope.
Permit scope
The municipality may require plans, sections, elevations, details and supporting forms based on the actual work.
Technical coordination
Structural, HVAC, plumbing, energy or other information may be required where affected by the project.
What the project package may need to communicate
The exact documents depend on the property, building, proposed work, municipality and professional scope. A coordinated set should explain the work clearly enough for the applicable review.
Existing-condition plans
Show the parts of the house and site that matter to the proposed work.
Proposed floor plans
Show room use, dimensions, openings, stairs, fixtures and construction changes.
Elevations & sections
Communicate exterior changes, heights, assemblies and vertical relationships where required.
Site & zoning information
Connect proposed work to property lines, setbacks and other site information when applicable.
Construction details
Explain assemblies, connections and project-specific details needed for review.
Technical information
Coordinate structural, HVAC, plumbing, energy or other information when required by the scope.
Garage and accessory-structure permit drawings should distinguish attached, detached and smaller accessory-building conditions. Site placement, setbacks, height and construction details can change the applicable permit path.
Garage & Accessory Structure Permit Drawings: project-specific permit considerations
Garage permits and garage drawings
Garage permits depend on the garage size, location, use and relationship to the house and lot. A garage drawing can show one part of the proposed work, while complete garage drawings may include site, floor plan, elevation, section, foundation and framing information.
What garage permit drawings can include
Depending on the accessory building, the permit package can include:
- site plan showing the structure, property lines and existing buildings
- floor plan, elevations and building sections
- foundation/slab, wall and roof construction details
- structural framing information within applicable BCIN scope
- garage/carport opening, door and connection details where relevant
- zoning statistics and permit coordination where included
What we check before the structure is designed
Accessory buildings are frequently limited more by the lot than by the desired floor plan.
- setbacks, height, lot coverage and permitted location
- whether the structure is detached or attached to the house
- intended use: vehicle storage, ordinary storage, workshop, cabana or another use
- whether plumbing or other building services are proposed
- trees, easements, overhead conductors and site-access constraints
- relationship to an existing driveway, house, fence and neighbouring structures
Detached garage permits
A detached garage is an accessory building with its own zoning and permit considerations. The site plan, building size, height, foundation and structural framing all need to be coordinated with the property.
Attached garage & carport
When the garage or carport is attached to the house, it is generally treated as part of an addition/alteration to the main building rather than as a completely independent backyard structure. Connection, fire/life-safety and structural conditions can therefore change.
Sheds & accessory structures
Ontario’s Building Code provides a permit exemption for a qualifying storage shed not more than 15 m² when it is one storey, detached, used only for storage ancillary to a principal building and has no plumbing. That exemption does not mean every accessory structure under 15 m² is permit-free, and zoning/property rules still need to be checked.
After the permit is issued
Construct the building in the approved location and from the approved foundation/framing details. Moving the structure or changing its size, roof, openings or structural system can affect zoning and permit compliance.
How the permit drawing service moves forward
A clear sequence helps separate feasibility, design, documentation and municipal review without implying that any approval result is guaranteed.
Property / Project Review
Review the address, proposed work or use, available drawings and the main zoning/permit questions.
Existing Information
Confirm the measurements, survey/base-building information, photographs or consultant inputs needed for the accepted scope.
Permit Documentation
Prepare and coordinate the drawings and supporting information included in the written service agreement.
Submission / Review
Support the agreed municipal submission or comments process; added revisions and new requirements are handled as separate scope where applicable.
What to send for a project review or quote
Good starting information helps identify the correct service and avoids guessing about the building or property.
- property address and municipality
- survey or site plan if available
- type of structure: detached garage, attached garage/carport, shed, cabana or other
- approximate width, depth and height
- photos of the proposed location and nearby buildings/property lines
- whether plumbing, heating or other services are planned
The issued permit is the construction reference.
Contractors and owners remain responsible for construction, site safety, inspections and building in accordance with the issued permit documents. Material field changes should be reviewed before they are constructed because revised drawings, engineering or municipal approval may be required.

Short answers first, with project-specific limits stated clearly.
Does a small shed need a building permit?
A qualifying storage shed can be exempt under the Building Code when it meets the specific exemption conditions. Other accessory structures and sheds that do not meet those conditions can still require a permit.
Can I put a garage anywhere in the backyard?
No. Zoning regulates where accessory buildings can be located and can control setbacks, height, coverage and other standards.
Is an attached garage the same as a detached garage for permits?
No. An attached garage interacts directly with the house and is generally reviewed as an addition/alteration, with different connection and life-safety considerations.
Can I add plumbing to a shed or cabana?
Plumbing changes the permit and servicing scope. The small-shed exemption does not apply to a shed with plumbing.
Do I need a survey?
Reliable property information is often important because the municipality needs to confirm setbacks and location.
Can 828 Design prepare the structural details?
We can provide building-structural design within applicable BCIN scope and coordinate separately regulated professional input where required.
What information should I send for a Garage & Accessory Structure Permit Drawings quote?
Send the property address, a short description of the proposed work, photos and any survey, existing drawings, permit records or municipal comments you already have. The final information list depends on the actual project.
Can existing conditions change the drawing scope?
Yes. Older construction, concealed conditions, previous alterations or incomplete records can affect what can be responsibly shown and may require additional investigation or professional input.
