According to the National Building Code, what determines the size allowance for buildings?

The size allowance for buildings is determined by the face of the building to three streets, which addresses several important urban planning considerations. This criterion involves assessing how a building interacts with its environment and surrounding roadway systems, ensuring that buildings are appropriately set back from property lines for safety, aesthetics, and function.

By evaluating the facade of a building in relation to adjacent streets, the National Building Code aims to maintain proper sight lines, facilitate traffic flow, and ensure that there is enough space for sidewalks and pedestrian traffic. This guideline helps regulate how structures are positioned within a plot of land, ensuring they meet zoning requirements and community standards.

Other factors such as height, design, and landscaping can influence building code requirements but do not directly determine the size allowance in the same comprehensive way that street-facing aspects do. For instance, while height does play a role in limits set by zoning laws, it is typically secondary to how a building interfaces with surrounding properties and roadways.
