New Mexico adopted the 2009 International Energy Conservation Code (IECC) as its mandatory statewide energy code for both residential and commercial, effective 2011. The state, through its Construction Industry Division, enforces building codes statewide. Local jurisdictions can adopt newer or more efficient energy codes but must provide their own code enforcement. In late 2018, Albuquerque was in the process of moving to the 2015 IECC. New Mexico also has a "sustainable building tax credit" for new or renovated residential or commercial buildings, based on the certification level in the U.S. Green Building Council's LEED green building rating system.
