2021 Uniform Plumbing Code – UPC 1-2021 (IAPMO)
The 2021 Uniform Plumbing Code® (UPC), developed by IAPMO and approved through the ANSI consensus process, establishes minimum requirements for plumbing system design, installation, and inspection. It incorporates the latest safety, efficiency, and performance provisions used across residential, commercial, and industrial projects.
Highlights:
- Adds Appendix N for defining scald risk and Legionella prevention through temperature control
- Updates backflow prevention device standards and installation methods
- Expands temperature-limiting protections for hot water outlets
- Establishes safety requirements for rooftop appliances and raised platforms
- Revises T&P valve discharge piping provisions for clarity and safety
- Introduces requirements for leak detection and monitoring technologies
- Enhances potable water pump installation and performance standards
- Adds DWV system updates for materials, cleanout access, and venting configurations
- Reorganizes medical and fuel gas system chapters for improved usability
Who It’s For:
Plumbing engineers, contractors, inspectors, and code officials enforcing compliant plumbing installations under the 2021 UPC framework.

2024 ICC Performance Code for Buildings and Facilities – ICCPC-2024
The 2024 ICC Performance Code for Buildings and Facilities (ICCPC) provides a performance-based alternative to traditional prescriptive codes, enabling innovative building designs while maintaining essential health, safety, and welfare standards. Developed by the ICC as part of the 2024 I-Code suite, this code establishes functional objectives and performance criteria for evaluating new and existing buildings across all occupancy types. It supports design flexibility by allowing solutions tailored to specific project goals, site constraints, and emerging construction technologies.
Highlights:
- Functional statements and performance requirements for structural, fire, energy, and life safety systems
- Administrative structure divided into four parts: Administration, Building Provisions, Fire Provisions, and Appendices
- Appendices include performance groups, risk factors, and design documentation guidelines
- Clarifies documentation expectations including Concept Reports, Design Reports, and O&M Manuals
- New requirements for emergency planning and responder communication systems
- Updated guidance on damage tolerance, reliability, and system performance verification
- Aligns with 2024 I-Codes including IBC, IFC, IEBC, and IECC for consistent cross-code integration
- QR-coded references for code tracking and digital plan review systems
- Encourages adoption by jurisdictions seeking flexible, enforceable alternatives to prescriptive codes
Who It’s For:
Architects, engineers, code officials, and developers using performance-based design approaches in complex, innovative, or non-traditional projects. Also suitable for jurisdictions seeking to support custom solutions while maintaining regulatory compliance.
