One of the primary reasons for delays in obtaining a building permit come from clients submitting insufficient or incomplete plans.
Here’s what our inspectors will require – in general – for various projects. Note that scale drawings of all projects are required by provincial law.
Post spacings, footing details, post sizes (6x6 mandatory), beam construction details, joist details (size, span, spacing); drawing may be required for complex decks/structures.
Footing/frost wall details (or engineered slab plan), wall details, roof system details.
Simple additions, houses:
Floor plan mandatory, footing/foundation details, beam composition, joist (size, span, spacing), wall details (studs, sheathing, insulation, cladding), lintels, roof system (truss/rafter, insulation, sheathing, roofing material)
Neat, scale/scalable drawing of all floors, footing/foundation details, beam composition, joist (size, span, spacing), wall details (studs, sheathing, insulation, cladding), lintels, roof system (truss/rafter, insulation, sheathing, roofing material), beam and post details (if applicable) egress window locations, soil gas pipe location, slab insulation (if applicable/required). If there are interior stairs, details on this are required to verify rise/run.
All of the above, plus fire separation details (referenced to Part 9 assemblies, ULC-tested assemblies, or Appendix D), with requirement for STC 50 between units.

All required fire separations must be referenced to Part 9 or ULC-tested assemblies, or be referenced to Appendix D. Note requirement for STC for residential suites adjacent to other occupancies.
