Water Smart Home Program

Developed by the Water Authority and Southern Nevada Home Builders Association, the Water Smart Home program promotes water efficiency, requiring homes built through the program to include water-smart landscaping and water-efficient appliances.

To find a Water Smart Home, contact the builders below to find out more about the homes and neighborhoods they have built as part of the Water Smart Home program.

For home builders

Are you with a home builder interested in participating in the Water Smart Home program?

One of the goals of the Water Smart Home is to educate potential home buyers about the benefits of buying a water-efficient home. Participating builders benefit from these promotional efforts, and Southern Nevada residents gain environmentally-friendly housing options. Home builders participating in the program can use the program logo and materials in advertising.

To participate, home builders must agree to the following:

  • Follow Water Smart Home program requirements for water efficiency in new residential homes and/or communities
  • Participate in a mandatory program briefing
  • Allow inspections of randomly selected Water Smart Homes prior to occupancy

To learn more, get specific technical standards, or start the process to become a participating home builder, submit a Business Interest Form. A staff member will follow up with you within 7 to 10 business days.

This program is co-sponsored by the Water Conservation Coalition.
