About us

The Interstate Compact on Industrialized/Modular Buildings was created to promote uniformity and encourage coordination in state industrialized buildings programs in a manner to assure interstate reciprocity.

An agency of the member states, the Interstate Industrialized Buildings Commission (IIBC) was established in 1992 and is responsible for carrying out the activities of the compact.

Between 2008 and 2017, registered manufacturers in 44 states and five provinces manufactured 58,644 certified modules.
