When partitions extend to within 15% of the ceiling height, rooms separated by the partitions are not considered as separate rooms.

When partitions extend to within 15% of the ceiling height, rooms separated by the partitions are not considered as separate rooms.

• A. True
• B. False
• C. Not specified
• D. Depends on partition material

Answer: (B)

When counting rooms for fire alarm and detection considerations, a barrier that reaches up near the ceiling still serves to separate spaces. The goal of a partition is to enclose an area from others to limit the spread of smoke and heat, and reaching within a small distance of the ceiling is typically enough to establish two distinct spaces. The tiny gap at the top does not negate that separation for most room-count and zoning calculations, so the idea that reaching within 15% of the ceiling height would prevent two areas from being treated as separate rooms isn’t correct. Materials or unspecified conditions don’t override this height-based separation rule, so the statement is false.
