Permit applications must include detailed, dimensioned drawings that are accurately scaled and clearly illustrate the proposed construction. Below, you will find the specific designer requirements for drawings applicable to various permit types.
Addition or Alteration to a Residential Dwelling Unit
Drawings are required to be prepared by a qualified designer who possesses their Building Code Identification Number (BCIN) qualification in House, or by the Owner on title of the municipal address that a permit is being applied for. More complex design such as Heating, Ventilation and Air Conditioning (HVAC) systems may require design by a qualified designer with BCIN qualifications for HVAC House. Building Services staff will review and advise you of the minimum requirements for your project. Please refer to the Permit Application Requirements for Addition/Renovation page and to the Basement Finishing Guide for further guidance.
New Residential Dwelling Units
Drawings are required to be prepared by a qualified designer who possesses their Building Code Identification Number (BCIN) qualification in House, or by the Owner on title of the municipal address that a permit is being applied for. More complex design such as Heating, Ventilation and Air Conditioning system will require design by a qualified designer possessing BCIN qualification for HVAC House. Please refer to the Permit Application Requirements for New Homes page for further guidance.
Residential Decks
Drawings are required to be prepared by a qualified designer who possesses their Building Code Identification Number (BCIN) qualifications for House, or by the Owner on title of the municipal address that a permit is being applied for. Please refer to the Residential Deck Guide and the Guards for Residential Decks guide for further guidance.
Plumbing Only for Residential
Plumbing permits are required to be obtained for any new plumbing, or modifications to an existing plumbing system (connected piping, fittings, valves, equipment, underground repairs, fixtures and appurtenances contained in plumbing). Drawings are not typically required for a plumbing permit when there is no proposed change to a floor plan. A completed building permit application form clearly outlining the proposed work is required. Please speak to Building Services staff for further guidance.
Demolition of a Building
Demolition permits are for the demolition of an entire building, or substantial building removal. Interior demolition would require a renovation or alteration building permit.
Before a permit can be issued, a completed Confirmation of Arrangements for Service Disconnections and Notifications form must be completed. A professional engineer (P.Eng) will be required if any of these apply;
- the building exceeds 3 storeys in building height or 600 m² in building area,
- the building structure includes pre-tensioned or post-tensioned members,
- it is proposed that the demolition will extend below the level of the footings of any adjacent building and occur within the angle of repose of the soil, as drawn from the bottom of such footings, or
- explosives or a laser are to be used during the course of demolition.
Please speak to Building Services staff for further guidance if any of these apply.
Rooftop Solar Panel Array
Building permit applications for the installation of rooftop solar array panels will require drawings and a structural review of the roof, prepared by a professional engineer (P.Eng). Please speak to Building Services staff for further guidance.
Tenant Alteration for Non-Residential
Building permit applications typically require drawings such as architectural, mechanical (HVAC, plumbing, sprinkler) and electrical that clearly explain the full scope of work. Structural drawings may also be required if the scope of work proposes a modification to the existing structure. Typically, architects and professional engineers (structural, mechanical, electrical) will be required to perform the design. Drawings are required to clearly indicate the existing and the proposed scope of work.
Note: In some circumstances an architect or professional engineer may not be required. Please speak to Building Services staff for further guidance, or contact the Ontario Association of Architects at www.OAA.on.ca or the Professional Engineers of Ontario www.PEO.on.ca to determine when a professional design is required to meet the O.B.C.
Change of Use
Even if no construction is proposed, a building permit may be required. A change of use permit would recognize any proposed changes that would result in an increase in hazard. Similar to Tenant Alteration applications, a professional design may be required. Please speak to Building Services staff for further guidance.
New Industrial Building, Large Multi-Unit Residential, or New Non-Residential Building Larger than 600 square metres
Building permit applications for proposed construction of this nature typically require drawings that are prepared by an architect as well as a professional engineer in each of the designations listed below that clearly explain the full scope of work. This applies to both new buildings, as well as to renovations or additions to existing buildings.
- Architectural (floor plans, reflected ceiling plans, roof plan, elevations, building sections, wall sections, details, door and window schedules, specifications)
- Civil (site works such as plumbing, storm water, sewer, lot grading)
- Landscape
- Structural (foundations, floor plans, column schedules, rack storage, details and specifications)
- Mechanical (plumbing and HVAC plans, including roof plans, sprinkler, details and equipment schedules, specifications)
- Electrical (lighting, power, fire alarm plans, details and schedules, specifications)
Due to the complexity of this type of permit application, it is suggested that a pre-consultation is arranged to discuss your proposed project and the application requirements. Please call to arrange a time to meet with Building Services staff at 705-742-7777 ext 1892.
Remember: In most cases it is against the law to begin construction or demolition of a building, including plumbing works without the authority of a building permit.
