What types of buildings are covered under NFPA 13R?

The National Fire Protection Association (NFPA) 13R specifically addresses the requirements for the design and installation of automatic sprinkler systems in residential occupancies. This code is particularly focused on buildings that are up to four stories in height and are primarily used for residential purposes, such as apartments, condominiums, and similar living arrangements.

NFPA 13R allows for a more straightforward and cost-effective approach to fire protection in smaller residential buildings compared to NFPA 13, which applies to larger commercial and industrial facilities. The provisions within NFPA 13R recognize that buildings of this scale have different risks and complexities, allowing for design criteria that are tailored to the unique needs of low-rise residential structures.

By focusing on residential occupancies up to four stories, NFPA 13R ensures that the necessary protections are established without imposing the more stringent requirements that might be necessary for larger or more complex buildings. This makes it easier to provide adequate fire protection while also being mindful of cost and practicality for residential developers and owners.
