How detailed should your plans be?


You may draw your own plans, however single line or pencil drawings are not acceptable. All plans must be drawn to scale in either metric or imperial measurements. Incomplete applications or drawings may not be accepted.

Content Requirement for Plans, Drawings and Specifications

Plans, drawings and specifications should provide sufficient information to enable City staff to determine whether the proposed construction, once completed, will comply with the requirements set out in the Building Code and in applicable laws.

The Building By-law Schedule C, sets out the specifications and documents required to submit along with the application form. If you have any questions, the Building Official or Building Technical Support staff at the Client Service Centre counter will be pleased to assist you.

Generally,

  • All drawings must be on durable material, drawn to scale and fully dimensioned (sketches are not acceptable).
  • We will not accept drawings in pencil, but photocopies of penciled drawings are acceptable.

Note:
Your application form must be accompanied by the documents noted in Schedule "C" of the Building By-Law including:

  • Two sets of building plans (floor plans, elevations and cross-sections and details, roof truss drawings, as appropriate)
  • Two copies of your property survey or site plan

Your plans may require:

  • Site plan
  • Cross section(s)
  • Elevation views
  • Structural framing details
  • Foundation plan
  • Floor plans
  • Roof plan for complex designs
  • Drainage and grading plan

See specific Residential Construction Checklists for full details.

Woodstoves

For the installation of any wood-burning appliance, please include a detailed installation plan and the manufacturer's installation instructions.

What is a Site Plan?

A site plan identifies buildings and other features in relation to property boundaries. The site plan must identify your existing house, other existing structures (i.e. garages, sheds, decks) and proposed additions or new structures.

Most or all of the information required for a site plan can be found on your property survey. You may have received a survey when you purchased your home. Plans of property can be obtained from the Ontario Land Registry Office.

The following information should be shown on a site plan:

  • Title and scale
  • Legal description
  • Street name
  • Driveway
  • North arrow
  • Property lines with dimensions
  • Setbacks (distance) to all property lines from all existing and proposed structures
  • Proposed construction (shaded)
  • Overall building dimensions, lot coverage, new and existing building areas of all buildings
  • Right-of-way and easements
  • Location of well & septic system (if applicable)

For interior renovations, an interior plan (key plan) may be required showing the location of both existing and proposed construction. The Building Official or Building Technical Support staff at the Client Service Centre counter will advise you.

What should be illustrated on a Floor Plan?

Floor plans are required for each floor level to be constructed or that is affected by your project. For additions to existing buildings, floor plans of all or part of the existing building may be required. The following information must be shown on a floor plan:

  • Title and scale
  • All room names or uses (e.g., kitchen, living room, bedroom, etc.)
  • Location of plumbing fixtures
  • Size, direction and spacing of structural members (joists, columns, beams and lintels)
  • Interior and exterior dimensions, including door and window sizes
  • Materials to be used
  • The extent and size of both the new and existing structures

Note: If your project includes the use of proprietary engineered floor joist systems, your submission must include a floor joist layout plan from the manufacturer.

What are Roof Framing details?

Roof and ceiling framing members must be clearly noted on the appropriate floor plan. Spans of all prefabricated roof truss and joist systems, including the location of all hip or girder trusses, must be shown. For other than simply supported spans, a detailed framing or roof truss layout provided by your truss supplier may be required.

Existing loading conditions can also affect structural design for building renovations and additions. The existing roofing and ceiling details should also be indicated.

What should a Cross-Section detail show?

A cross-section presents a view of a house along an imaginary cut, showing the structural elements of the building and exposing what is hidden behind the walls. Cross-sections through the proposed and existing structure(s) may be required to show building materials and how they relate to one another. The location of the cross-section is shown by the cross-section symbol on the floor plans.

The following information must be shown on a cross-section:

  • Title and scale
  • Room names
  • Heights and dimensions of doors and windows
  • Size and types of materials and finishes
  • Finished floor level and grades
  • Extent of existing house and proposed additions

What is an Elevation View?

An Elevation View is an illustration of a finished exterior of each side of the building or frontage. Elevation drawings are required for any project that may alter the exterior of your building.

The following information must be shown on an elevation:

  • Title and scale
  • Heights and dimensions of existing and new window and door openings
  • Exterior finishes and materials
  • Finished floor levels and grade
  • Extent of proposed addition and existing house
  • Overall height of building
  • Slope/pitch of new roofs
