WASHINGTON – January 17, 2025 –The National Housing Survey, conducted by the American Institute of Architects (AIA) and the U.S. Conference of Mayors (USCM) found that mayors anticipate the total housing shortfall, currently estimated at between 4 and 7 million units, will increase by more than 2 million units over the next five years, underscoring the immediate need for bold federal action. Findings from the USCM-AIA National Housing Survey highlight widespread concerns from mayors about escalating costs, insufficient federal funding, and onerous regulatory requirements.
