Reyes and Texas Attorney General Ken Paxton, including 15 states and the National Association of Home Builders, has taken legal action against the U.S. Department of Housing and Urban Development (HUD) and the U.S. Department of Agriculture (USDA), challenging new energy efficiency standards they believe will exacerbate the affordability crisis in housing, according to the Utah Office of the Attorney General.
