The "Building Housing Communities Act" aims to enhance New Mexico's housing inventory by designating municipalities that adopt voluntary planning and zoning strategies to improve housing affordability and accessibility. The Department of Finance and Administration is tasked with establishing a program to award certificates to municipalities that implement approved strategies, thereby designating them as "building New Mexico communities." The act emphasizes the need for diverse strategies that cater to the unique needs of urban and rural areas, as well as best practices from both local and state governments.

Additionally, the act outlines the department's responsibility to develop rules for effective strategies that address various barriers to housing development, including land use and zoning policies, complexity in jurisdictional reviews, and construction costs. The provisions of this act are set to take effect on July 1, 2027.
