Low-Rise Residential Occupancies are buildings typically how many stories?

• A. 10+ stories
• B. 7-9 stories
• C. 4-6 stories
• D. 1-3 stories

Answer: (D)

Low-rise residential occupancies are buildings up to three stories tall above grade. This category is defined that way because NFPA 13R is designed to provide cost-effective sprinkler protection for small, typical residential layouts with simpler hydraulics and lower water demands. When a building has more than three stories, the fire protection needs become more substantial and are addressed by other NFPA 13 family standards for mid-rise or high-rise construction. So the typical height for low-rise residential buildings is one to three stories, which is why the correct choice is the one-story range up to three.
