Build America, Buy America Act (BABA)

This site provides a comprehensive collection of proposed, currently effective, and expired waivers (as they become available) of the Build America, Buy America Act’s domestic content procurement preference as applied to HUD’s Federal Financial Assistance programs.


The Build America, Buy America Act (the Act), enacted as part of the Infrastructure Investment and Jobs Act on November 15, 2021, established a domestic content procurement preference for all Federal financial assistance obligated for infrastructure projects after May 14, 2022.  The domestic content procurement preference requires that all iron, steel, manufactured products, and construction materials used in covered infrastructure projects are produced in the United States.


Agencies may waive the domestic content procurement preference if (1) a waiver is in the public interest, (2) the types of iron, steel, manufactured products, or construction materials are not produced in the United States in sufficient and reasonably available quantities or satisfactory quality, or (3) the application of the domestic content preference would increase the cost of the overall project by more than 25 percent.
