Answer: ICC-ES is a nonprofit, limited liability company that does technical evaluations of building products, components, methods, and materials. If it is found that the subject of an evaluation complies with code requirements, then ICC-ES publishes a report to that effect, and makes the report available to the public. ICC-ES evaluation reports are intended mainly to aid agencies that enforce building regulations, by assisting them to determine code compliance. On the other hand, companies that hold evaluation reports find them to be of great value, because their products have been recognized as code-complying by an organization known for its independence, impartiality, and technical expertise.

ICC-ES also has growing programs for evaluation of plumbing, mechanical, and fuel gas products, and of “green” building products.
