Site PlanArchitectural DrawingsStructural DrawingsMechanical, Electrical, and Plumbing (MEP) Drawings (if applicable)Energy Efficiency Compliance
Each of these categories has specific requirements that will be detailed below.

3. Site Plan
A site plan is essential for demonstrating how the construction fits within the property’s boundaries. This drawing must be to scale and must show:

Property Boundaries: Clearly outline the property lines and indicate the location of the building(s).Setbacks: Show the distance from the proposed structure to the property lines, streets, and neighbouring buildings.Access Points: Mark all entryways, parking, and driveways.Utilities: Indicate the locations of water lines, sewers, and stormwater management systems.Landscape Features: Include trees, retaining walls, and any other significant landscaping.Zoning Information: Ensure the building complies with local zoning laws, including height restrictions, lot coverage, and land use.

Required Documents:
Must be signed and sealed by a licensed professional.Typically drawn to scale (e.g., 1:200 or 1:500).

4. Architectural Drawings

Architectural drawings provide an overview of the building's design, dimensions, and layout. These include:

Floor Plans: Detailed layouts of each floor, including room sizes, wall placements, windows, and doors.Elevations: Exterior views from all sides, including the building's height, roof design, and finishes.Sections: Vertical slices of the building that show interior heights and the relationship between floors.Details: Large-scale drawings that focus on elements like walls, windows, and stairs.

Required Documents:
Must be signed and sealed by a registered architect or designer, if required.Drawn to scale (typically 1:50 or 1:100).

Foundation Plan: Layout of footings, foundation walls, and reinforcements.Framing Plan: Details of the structural framework, including beams, columns, and load-bearing walls.Structural Details: Specific connections and junctions (e.g., beam-to-column, anchoring).Load Calculations: Structural engineers must provide calculations to demonstrate the building’s stability.

Required Documents:
Must be signed and sealed by a Professional Engineer (P.Eng) licensed in Ontario.Include relevant calculations and specifications.

6. Mechanical, Electrical, and Plumbing (MEP) Drawings

These drawings may be required for projects involving the installation or modification of mechanical, electrical, and plumbing systems:

Required Documents:

Must be signed and sealed by a licensed professional (e.g., electrician, plumber, or mechanical engineer).Must comply with Ontario’s Electrical Safety Code and Plumbing Code.

7. Energy Efficiency Compliance

Energy Modeling: For certain building types, energy modeling may be required to predict energy performance.Compliance with the Energy Code: Documentation showing that the building meets Ontario Building Code energy standards, such as insulation, windows, and HVAC systems.

Required Documents:

Report or documentation prepared by a Certified Energy Advisor.Energy simulation models or results.

8. Additional Considerations

Zoning and Land Use: Ensure the project aligns with local zoning bylaws, which may affect building height, setbacks, and land use.Heritage Considerations: Projects involving heritage buildings may require additional studies and approvals.Accessibility: Depending on the building type, compliance with accessibility regulations may be necessary.
