The minimum design criteria for a new sprinkler system in a residential occupancy, considering noncombustible concealed spaces and based on NFPA 13, would typically involve 4 sprinklers at a density of
0.10 gpm/ft². This provides a baseline level of fire protection suitable for residential settings.
