Version 1.2 of the WaterSense New Home Specification became effective on July 24, 2014. This specification establishes the criteria for new homes labeled under the WaterSense program and is applicable to newly constructed single-family and multi-family homes. Version 1.2 contains minor revisions to Version 1.1 that effectively expand the pool of eligible irrigation professionals who can design or install and audit the irrigation system to any irrigation professional certified by a WaterSense labeled program. On February 15, 2018, WaterSense released a Notice of Intent (NOI) to release Version 2.0 of the WaterSense Home Specification with the intent of revising the specification and certification requirements for WaterSense labeled homes.

Notice of Intent (NOI) to Revise the Specification

On February 15, 2018, WaterSense released a Notice of Intent (NOI) to revise the specification and certification requirements for WaterSense labeled homes. EPA is looking to: reexamine the specification and certification process to allow for more flexibility in the technical requirements; streamline the program requirements and certification process; adapt to the evolving market for home building; encourage the adoption of emerging technologies and practices; and facilitate increased use of the specification. Read the NOI to learn more.
