A fire wall must be continuous from the foundation floor to a height:

• A. At the Foundation Floor
• B. To the Top of the Roof
• C. Above the Roof as Required by the Local Building Code
• D. To the Next Floor Above

Answer: (C)

A fire wall is meant to create an ongoing barrier that stops fire from moving from one area or building to another. Because fire can spread upward through concealed spaces and around the roof, the wall must extend beyond the roofline to a height specified by the local building code. Extending above the roof ensures there’s no gap at the roof level that fire could breach and helps maintain the separation even if the roof area is exposed to heat or collapse. So the requirement is for the wall to rise from the foundation all the way to a height above the roof, as the code dictates.
