International Code Council Standards are a series of standards for buildings, unifying certain aspects of their design and construction to promote compatibility and reliability. They are revised and re-released every 3 years to stay up to date.
Here they are organized by year, with all the codes from a specific year grouped together to make it easier to purchase all of a single year's codes when dealing with new developments or to find the relevant codes when looking at an older building.
As the voice of the U.S. standards and conformity assessment system, the American National Standards Institute (ANSI) empowers its members and constituents to strengthen the U.S. marketplace position in the global economy while helping to assure the safety and health of consumers and the protection of the environment.
