• A. High-Rise Commercial Occupancies
• B. Industrial Facilities
• C. Low-Rise Residential Occupancies
• D. One- and Two-Family Dwellings

Answer: (C)

NFPA 13R is the standard for automatic sprinkler installations in low-rise residential occupancies. This means it covers buildings like houses, apartment buildings, and other residential structures that are typically up to three stories high. The goal is to provide reliable fire protection for occupants in common living settings while keeping the design practical and cost-effective for low-rise construction. Because it is tailored to residential risk and water supply realities of smaller buildings, it isn’t intended for high-rise commercial occupancies or industrial facilities, which require different design criteria found in other NFPA sprinkler standards. While one- and two-family dwellings fall under residential protection, the overall scope is best described as low-rise residential occupancies.
