State, Tribal and Local Green Building Codes

Over 275 cities, counties, tribes and states have created building codes or building programs to increase the environmental and health performance of their communities.   Examples of some such codes and programs are listed on this page. Virtually all of these jurisdictions have codes that  meet federal energy conservation guidelines, and many have codes that far exceed federal energy guidance to cover a wide range of green building practices that make buildings healthier; conserve energy, water, and natural resources; and reduce power and water costs.
