City of Austin Fire Flow Requirements
for Residential Construction

Beginning in January 2014, the City of Austin began to formally review for the fire-flow requirement for houses larger than 3600 SF. Fire-flow for residential construction varies based upon size and construction type (see Table B105.1, 2012 International Fire Code) If a property does not have the required fire-flow, the code allows for alternate methods of compliance including the installation of sprinklers or an increase in the fire rating of the construction. This is not to be confused with Texas Occupation Code Section 1301.551 (i) where state law prohibits requiring the installation of a multipurpose residential fire protection sprinkler system.

Note: A residential sprinkler system designed, installed and tested in accordance with the 2016 NFPA 13D or the 2015 IRC P2904 standards will be installed for Lot #1B: The plans for the sprinkler system must be designed and installed by a Texas Licensed Sprinkler contractor for NFPA 13D systems or a Texas Licensed Plumber with the Multipurpose Residential Fire Protection Sprinkler Specialist (MRFPSS) endorsement. The Sprinkler plans must be submitted, reviewed, approved, tested, and inspected by AFD prior to covering the walls and ceilings. A flow test of the most demanding area will be required.
