What is the maximum height for buildings that Part 9 applies to?

Part 9 of the National Building Code of Canada (NBC) specifically applies to residential buildings that are typically considered low-rise. This section is relevant for the construction of buildings that have a maximum height of 3 storeys.

The rationale behind this limit is tied to the health and safety regulations that Part 9 encompasses, which are designed for buildings that are smaller in scale and complexity compared to those that fall under Part 3 of the code. Part 9 includes provisions related to structural integrity, fire safety, and accessibility requirements that are manageable for buildings of this height.

Understanding the application of Part 9 is essential for architects, as it outlines simplified requirements for designs, construction methods, and materials that best suit low-rise residential environments. Knowledge of the maximum height ensures compliance with regulations and contributes to safer building practices in Canada.
