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

• A. Above the roof as required by the local building code
• B. To the top of the first floor
• C. To the eave line
• D. To mid-height of the building

Answer: (A)

Fire walls are designed to form a continuous barrier that prevents the spread of fire from the foundation up through and beyond the roofline. Extending the wall to a height above the roof, as required by the local building code, ensures the fire separation remains continuous even if burning reaches the roof and helps prevent heat and flames from crossing over the top. The exact height is determined by code, and extending above the roofline is the standard way to maintain the integrity of the fire wall. Stopping at the first floor, the eave line, or mid-height would break that continuity and fail to meet the intended protection.
