Which property line in R-5 zoned properties has the lowest percentage restriction for firewall construction?

In R-5 zoned properties, the rear property line typically bears the lowest percentage restriction for firewall construction due to the orientation and usage of space in residential zones. Firewalls are primarily used to prevent the spread of fire between structures and to protect adjacent properties.

The rationale for the rear property line having lower restrictions is that it is usually less likely to experience direct exposure to neighboring structures compared to side property lines, which are often adjacent to other buildings. This reduced exposure means that there is less risk involved, allowing for more flexibility in construction while still meeting safety standards.

Furthermore, zoning regulations recognize the need for practical space utilization in residential areas, which can be enhanced by allowing more lenient fire safety measures on the rear property line. Therefore, the correct selection reflects the zoning strategy aimed at balancing safety with property rights and development potential in R-5 zones.
