Which two national plumbing codes are most commonly referenced for residential plumbing, alongside local amendments?

• A. International Building Code and Uniform Plumbing Code
• B. International Plumbing Code and Uniform Plumbing Code
• C. International Plumbing Code and National Electrical Code
• D. Uniform Plumbing Code and International Building Code

Answer: (B)

The main idea is identifying the two model codes that specifically govern plumbing in residential work, aside from local amendments. The two most commonly referenced are the International Plumbing Code and the Uniform Plumbing Code. The IPC, published by the International Code Council, provides a comprehensive set of requirements for designing, installing, and inspecting plumbing systems. The UPC, published by IAPMO, is another widely adopted plumbing standard with its own structured guidelines. Local jurisdictions typically adopt one of these codes and modify it with amendments to fit local conditions such as climate or water supply. The other options mix in the building code or the electrical code, which cover broader or different scopes and aren’t the primary plumbing standards used for residential work. So the best pairing to reference for residential plumbing is the International Plumbing Code and the Uniform Plumbing Code.
