AZ HB2761

Changes the effective date for water conservation plumbing requirements from January 1, 1994 to January 1, 2024 for residential construction and from January 1, 1994 to January 1, 2024 for commercial, industrial, and public construction.

Replaces specific water consumption standards (e.g., 3 gallons per minute for faucets, 1.6 gallons per flush for water closets) with requirements that plumbing fixtures meet WaterSense program labeling standards or efficiency criteria established before January 1, 2024.

Adds "watersense-labeled plumbing fixture" and "watersense program" to the definitions section, referencing the EPA's WaterSense program established under America's Water Infrastructure Act of 2018.

Updates the definition of "water free urinal" to reference the ASME standard A112.19.19 (effective January 1, 2023) instead of older ASME and ANSI standards.

Adds authority for the director to waive the article's requirements for historic fixtures as determined by rule.
