What is the minimum fire separation distance for residential buildings?

The minimum fire separation distance for residential buildings is typically established to reduce the risk of fire spread from one structure to another. A distance of 5 feet is generally accepted in many code jurisdictions as it allows for adequate space for fire protection measures, such as the installation of fire-rated walls or other fire-resistive construction elements, as well as providing access for firefighting efforts.

This distance is significant because if structures are located too closely together, the potential for flames to leap from one building to another increases, posing a greater risk to life and property. In many codes, the specific requirements may vary depending on factors like the type of occupancy, materials used in construction, and local amendments, but 5 feet is a common minimum established to ensure safety while still accommodating necessary development and land use considerations.
