For exterior wall projections where the fire separation distance is greater than 3 feet but less than 30 feet, what is the additional distance added for every foot beyond 3 feet?

The standard regulation for exterior wall projections in relation to fire separation distance stipulates that for every foot beyond a distance of 3 feet, an additional allowance should be added to the projection allowable. When the fire separation distance exceeds 3 feet but is less than 30 feet, it is established that an increment of 8 inches is added for each additional foot.

This means that if a wall projection is situated at 4 feet from the property line, it is allowed to project 8 inches more than the base allowable projection. If the distance is 5 feet, then it allows for an additional 16 inches, and so forth, following this 8-inch increment for each foot beyond the 3-foot mark.

This regulation ensures that the building maintains adequate distance for fire safety, limiting the potential for fire spread from one structure to another. The importance of a specific increment like 8 inches is rooted in balancing safety with architectural flexibility, allowing some degree of projection while adhering to fire safety codes.
