What percentage of the total site perimeter may a firewall on two sides be constructed on R-5 zoned properties?

In R-5 zoned properties, a firewall can be constructed on up to 50% of the total site perimeter, which enables developers to effectively manage fire safety while maximizing the available space on their lot. This provision is particularly relevant in urban planning and building regulations, where the proximity of buildings can increase the risk of fire spread. By permitting firewalls on half of the perimeter, it allows for flexibility in building designs and ensures that there are adequate fire separation measures in place for safety.

The relevant regulations are often crafted to balance safety with development needs, thus the 50% allowance provides a reasonable approach to the construction of firewalls without overly restricting the use of the property. This is particularly important in residential zones like R-5, where density can lead to closer building placements.
