The 2009 editions of the
Uniform Plumbing
Code
(UPC) and
Uniform
Mechanical Code (UMC), published by the International
Association of Plumbing and Mechanical Officials, have been tentatively scheduled
for release March 1, 2009, completing a three-year consensus development cycle
accredited by the American National Standards Institute.
Significant
changes to the UPC
include:
- New
requirements for the installation of nonwater urinals
- Specific

requirements for listed and unlisted open flame decorative
appliances
The Uniform Codes are developed using
the American National Standard Institute's consensus development procedures.
This process brings together volunteers representing a variety of viewpoints
and interests to achieve consensus on plumbing and mechanical practices.
The codes are
designed to provide consumers with safe and sanitary plumbing and mechanical
systems while, at the same time, allowing latitude for innovation and new
technologies. The public at large is encouraged and invited to participate in
IAPMO’s open consensus code development process. A code development timeline and
other relevant information are available at IAPMO’s Web site,
