The Office of Management and Budget (OMB) has proposed new standards to determine if construction materials for federally funded infrastructure projects are made in the USA. The new guidance “sets standards to carry out the statutory requirement.” …Federally funded infrastructure projects include housing development that receives any federal support such as through the CDBG and HOME programs. The Build America, Buy America Act requires that OMB issue standards that define ‘‘all manufacturing processes’’ in the case of construction materials. …Among construction materials covered by the guidance are lumber, drywall, glass, and plastics. …A Federal awarding agency may issue a waiver to the application of the Buy America Preference. …OMB has provided only 30 days to comment on the new standard. NAHB will submit comments as we believe that, under OMB’s proposal as written, virtually all housing development could be excluded from the standard.
