Planning, Design and Construction
This chapter provides a summary of the planning, design and construction essentials for each aspect of wood-frame house construction described herein. The book has been updated to incorporate the requirements of the 2010 National Building Code (NBC) and the 2012 Interim Changes to the 2010 NBC for energy efficiency. However, it is not meant to replace the NBC. Consultations with municipal building officials during the design, plan approval and construction stages are strongly recommended to ensure that problems are avoided. Building codes generally describe the minimum measures required for building performance and safety. Some builders and consumers may wish to add features that exceed code requirements, such as additional insulation to reduce heating and cooling costs. Recent changes to the NBC require that houses have a minimum level of energy efficiency that affects building envelope construction
(Chapter 5), service water heating systems (Chapter 19), and heating, ventilation and air conditioning systems (Chapter 20).
APPROVALS, PERMITS AND INSPECTIONS The system of approvals, permits and inspections for house construction can be quite complex. It is important to ensure that the property is zoned for the intended use before proceeding with house planning. Some properties may have development regulations, covenants or restrictions governing the size, location and exterior finishes of the house. Requirements for drawings, permits and inspections vary across Canada, and special provisions may apply to suit local climatic and geological conditions. For example, the wet climates of both the east and west coasts require a drainage cavity in walls to resist rain penetration; varying snow loads across Canada result in the different structural capacities for roof members;
