What is the maximum height of the rear firewall of an R-3 zoned property with firewalls on the rear and side?

The correct answer, which indicates a maximum height of 3.2 meters for the rear firewall of an R-3 zoned property, aligns with building code regulations specifically designed to address fire safety and zoning requirements. In residential zones like R-3, firewalls are crucial for preventing the spread of fire between properties and ensuring adequate separation from adjoining structures.

The height limit of 3.2 meters is often established to balance fire safety with residential design considerations. This height supports the structural integrity and purpose of the firewall while maintaining an acceptable scale for residential areas. Going beyond this height may create issues such as increased fire risk, potential encroachment into neighboring spaces, and aesthetic concerns within the community.

In zoning and building regulations, each height allowance typically corresponds with specific uses and fire ratings, ensuring safer habitation and compliance with fire safety codes. Therefore, a maximum height of 3.2 meters is a standard that reflects a compromise between functionality and safety in the context of R-3 zoning.
