|Written by and for the people who do the work: plumbers, mechanical engineers, contractors, elected officials and inspectors. IAPMO is proud to utilize an open consensus process accredited by the American National Standards Institute (ANSI) in its code development practice. At its annual education and business conference, members and non-members alike — can have a voice and a vote on proposed changes to the code.||Final determination of code text is done through a governmental consensus process versus an open consensus process like IAPMO uses. Voting members are made up of “governmental member representatives and honorary members” (another word for bureaucrats). Notably, voting members do not appear to include the people who actually do the work. They are dominated by government building officers ad code enforcement officials.|
