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 April 2019, EPA published the Draft WaterSense labeled homes program, Version 2.0, which aims to further promote residential water efficiency and help enable market transformation in home construction. Learn more.

Version 2.0 WaterSense Homes

In April 2019, EPA released the WaterSense Draft Specification for Homes, Version 2.0. The revised specification will allow for more flexibility in the technical requirements for homes; 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. The program revisions will help ensure that WaterSense labeled homes are high performing with respect to water efficiency and homeowner satisfaction.
