What percentage of the side property line can a firewall occupy on an R-2 zoned property?

In R-2 zoned properties, building codes typically allow for certain structures, such as firewalls, to occupy a specified percentage of the side property line. A firewall serves crucial purposes, including providing fire protection between adjacent structures and ensuring safety in densely populated residential areas. The correct percentage occupancy for a firewall on an R-2 zoned property is 80%.

This requirement acknowledges the balance between maximizing usable space for construction while ensuring safety standards are met. Some options provided suggest lower percentages, which may not align with zoning regulations that prioritize safety under fire code requirements. Therefore, the 80% occupancy rule reflects a building practice aimed at ensuring that buildings are sufficiently protected from the risks posed by fire, particularly in areas with closely situated structures.
