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

• A. 2-4 stories
• B. 4-6 stories
• C. 1-3 stories
• D. 7-10 stories

Answer: (C)

Low-rise residential occupancies are defined by a small number of stories above grade, which drives the sprinkler design scope. In NFPA 13R, buildings in this category are typically one to three stories tall. This range reflects the simpler, more cost-effective coverage suitable for small residential structures, with less need for the higher complexity and water-demand considerations that come with taller buildings. If a building has four or more stories, it moves into mid-rise or high-rise territory and would usually fall under different design rules beyond NFPA 13R. So the best answer is the one that states 1-3 stories.
