Plans typically are not permit submission ready. Structural Engineering varies from region to region, based on seismic (earthquakes) restraint requirements. A regional structural engineer will need to be engaged to structurally engineer the plans. The proposed building may also be subject to energy modelling, therefore requiring a certified energy advisor. Plans are also based on the 2018 British Columbia Building Code and may need to be amended to suit the local or regional building codes, confirm with your local building department for local requirements.  Occasionally civil engineers are required to design on site storm water management, so check with your building department or developer if your property is subject to SWM plans.    On lots with side yard setbacks of 1.50 m or less may be limited for windows facing neighbouring properties, it is important to make sure the plan does not exceed the permitted windows. If it does some windows may need to be deleted, or reduced.
