What happens when codes do not integrate? BACK

“Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern.” 2024 IBC® and IRC® section 102.1

Despite what is promised or assumed, families of building codes have inherent conflicts. It is often left up to you and your team to resolve these problems. This potentially puts your inspectors in a compromising position, as the contractors may disagree or bid the work using alternative code language. There is an option that provides your constituents with the strongest set of codes that do not conflict with other model building and residential codes.

You need codes that demonstrate the best the industry has to offer. The Uniform Codes are the result of years of practical experience and applied

science through diverse stakeholder input and utilizing strict, consensus-based rules to ensure that no special interest can dictate content. IAPMO’s technical committees, subcommittees and working groups are filled with more than 250 expert volunteers dedicated to producing the most comprehensive, discipline-specific, turnkey document. This gathering of the minds from the entire industry yields a document that is enforceable rather than interpretative, while remaining flexible to embrace new technology as it enters your built environment.

Flawed code interpretations and conflicting code language:

  • Cost money
  • Waste time and cause delays
  • Can diminish health and safety

Since their inception, the Uniform Codes have seamlessly integrated with local building and structural codes. Due to the exhaustive efforts of our members and technical committees, as well as our rigorous code development process, the Uniform Codes do not conflict within themselves or with building codes developed by other organizations. The three-year code cycle provides continuous refinement, making great codes even better by being innovation friendly, countering health and safety threats due to unintended consequences, and adapting to how modern plumbing systems are designed, installed and used.


The Uniform Codes have a number of built-in free technical services:

  • Proven code integration with all interrelated construction codes
  • Early research and codification of new technology helps keep your jurisdiction competitive for attracting new business
    • We help your jurisdiction stay up to date
    • Early adopters respect your progressive jurisdiction
    • Any changes are backed up by committed, scientific proof
    • Quantify changes through robust working review
  • Free telephone hotline (800-201-0335) to anyone with a question – your team, your constituents and your contractors working in your jurisdiction
  • More than 160 staff members devoted to the plumbing and mechanical industry, including field managers dedicated to specific U.S. regions

Live by the Code™
Our codes and formal “rules” provide the background for civilized living. The plumbing and mechanical codes, and the men and women involved in enforcing them, are dedicated to protecting the public’s health and safety. These professionals spend years learning and applying the codes uniformly in our communities and constructing safe and responsible homes, workplaces and educational structures for present and future generations. We can all share this philosophy: We can accomplish greater things together than we can individually.
