Both codes are being developed through an American National Standards Institute (ANSI)-accredited process to help ensure the health, safety, and welfare of the public.
Broad Participation Encouraged
IAPMO is calling on members, contractors, manufacturers, inspectors, labor representatives, design professionals, and consumers to take part in the development process. Cooperative participation helps ensure that the codes serve the industry and the public effectively.
