Bathroom sprinklers are not required if the area is less than or equal to 55 ft².

• A. True
• B. False
• C. Only in multi-family units.
• D. In bathrooms only if vented.

Answer: (B)

In NFPA 13R designs for low-rise residential occupancies, you don’t exempt a bathroom from sprinkler protection simply because its area is small. The code requires sprinkler coverage in habitable spaces of a dwelling, and there isn’t a blanket allowance to skip sprinklers in bathrooms based on a 55 ft² size. Bathrooms can contain combustibles and can contribute to rapid fire growth, so providing protection there helps control ignition and limit spread to living areas. Therefore the statement is not correct. Bathrooms receive sprinkler protection regardless of whether their area is less than or equal to 55 ft².
