About Interstate IBC

Interstate Industrialized Buildings Commission (IBC) was created in 1991 when New Jersey became the third state following Minnesota and Rhode Island to enact the Interstate Compact for Industrialized/Modular Buildings (model legislation). IBC, which is responsible for carrying out the activities of the compact, is comprised of governor-appointed state officials from the member states and a representative from the industrialized (modular) buildings industry (list of commissioners).

On April 19, 2011, North Dakota became the fourth state to join the compact when Governor Jack Dalrymple signed Senate Bill 2284 into law. North Dakota had entered into an interim reciprocity agreement with IBC effective August 1, 2003 which allows a state to participate in the IBC program prior to becoming a full member.

The purpose of the compact is to promote and assure reciprocal recognition of states' industrialized buildings programs through effective implementation of uniform rules and regulations. It streamlines regulations that govern industrialized (modular) buildings -- from the design and manufacture to delivery and installation -- and eliminates overlapping and costly reviews and inspections by multiple jurisdictions. The coordinating compact enables member states to improve efficiency and reduce costs by consolidating similar services as they continue to operate, staff and enforce their industrialized (modular) buildings programs. Improved compliance through uniform rules, regulations and procedures; better enforcement through sharing of information and findings; and reduced costs through elimination of redundant reviews and inspections are just some of the compact's benefits.

The compact's rules, regulations and procedures are developed by the Rules Development Committee (RDC) and recommended to IBC for adoption. RDC is a consensus-based committee with representatives from state governments, consumers, residential and commercial manufacturers, and private evaluation and inspection agencies.

State of Wisconsin has a separate agreement with the State of Minnesota that allows industrialized (modular) buildings manufactured in Minnesota and bearing an IBC certification label to be sited in Wisconsin.

Since May 1, 2011, IBC has established and maintains its own offices with a fulltime staff (staff contacts). Previously, the National Conference of States on Building Codes and Standards (NCSBCS) had served as IBC secretariat since 1992, providing administrative and secretarial support.
