Homes Specification

Homes specs bannerFinal Specification for New Homes (Version 1.2 Effective July 24, 2014)

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 multifamily 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. 

In 2018, WaterSense initiated work to develop a revised Version 2.0 of the WaterSense homes program. In October 2018,  the program released a concept paper that describes proposed updates that may be included in Version 2.0. Learn more.

Version 2.0 WaterSense Homes

In February 2018, WaterSense released a Notice of Intent (NOI) that it is considering revisions to 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.
