What is the total length percentage of side firewalls permissible on an R-3 zoned property?

In the context of building codes for R-3 zoned properties, which typically include residential structures such as multi-family buildings, the total length percentage of side firewalls permissible is indeed 85%. This regulation is in place to ensure safe distances between structures and to minimize fire hazards, promoting both safety and compliance within residential communities.

The figure of 85% indicates that up to this percentage of the total length of a property can be taken up by side firewalls. This allows for effective fire separation, allowing for necessary structural integrity while also permitting sufficient openings for windows and ventilation on residential buildings. Understanding these regulations helps in making informed decisions during the planning and construction phases, thereby adhering to fire safety standards and local building laws.
