(A) Water supply for fire protection on lots, parcels, or tracts served by a public water system. No building, excluding one- and two-family dwellings, shall be constructed or enlarged unless such building is supplied with a water supply or fire protection meeting the following requirements:
(1) Buildings protected by automatic fire sprinkler systems. Buildings equipped with automatic fire sprinkler systems throughout shall have as a required fire flow, the flow demand required by the largest fire sprinkler system.
(2) Buildings not protected by automatic fire sprinkler systems. Buildings not equipped with automatic fire sprinkler systems throughout shall have as a required fire flow, the fire flow calculated by using the “Determination of Required Fire Flow” published by the Insurance Services Office, current edition. When the sustained fire flow cannot be obtained, the fire flow may be decreased by the installation of an automatic fire sprinkler system, upgrading of construction, providing alternative water supplies acceptable to the fire marshal, or a combination of any of the above.
(B) Water supply for fire protection on lots, parcels or tracts not served by a public water supply system. Where a public water supply system is not available, the fire flow shall be determined in accordance with NFPA 1, current edition as adopted by the Florida Admini strative Code. When a building requires a fire flow of five hundred (500) gallons per minute or less, an approved automatic fire detection system shall be installed in accordance with NFPA 72, current edition as adopted by the Florida Administrative Code. When a building requires a fire flow of more than five hundred (500) gallons per minute, an automatic fire sprinkler system shall be installed in accordance with the current edition of NFPA 13 as adopted by the Florida Administrative Code.
(C) Hydrants, quantity, and spacing for other than one- and two-family dwellings. The required fire flow shall be in accordance with the current edition of NFPA 1.
