Laundry to landscape systems do not require a permit as long as installers comply with
these requirements: (California Code of Regulations, Title 24, Part 5, Chapter 16A)
1. Contact your city and/or the county to see if it has regulations in addition to
state rules.

3. Install a three-way valve to direct graywater to the irrigation system or the sewer.
4. Do not connect to the potable water system, include a pump, or affect the plumbing,
electrical, mechanical, structural or safety features of the home.
