Monterey County, CA Landscaping Rules: Artificial Turf (2026)

There is no general Monterey County ordinance prohibiting synthetic or artificial turf on private property in the unincorporated area. Artificial turf is commonly used as a water-saving alternative and is generally permitted, which is consistent with the county's water-conservation focus and constrained supply. It can intersect with landscape and grading requirements: if installed as part of a project that triggers a water-efficient landscape ordinance (state MWELO, or MPWMD Rule 142.1 on the Peninsula) or site-development review, the turf must be shown on the required landscape/site plan, and drainage and impervious-surface considerations may apply. For larger installations, owners should confirm any drainage, setback, or permit requirements with Monterey County Building Services. Note that water-efficiency rules and rebate programs sometimes favor living low-water plantings over synthetic turf, and MPWMD landscape rules emphasize plant-based water-efficient design, so artificial turf may not earn the same incentives as a drought-tolerant planted yard. The strongest legal protection for artificial turf is state law: California Civil Code 4735 (originating with AB 349, 2015) makes it unenforceable for a homeowners association to prohibit the use of artificial turf or any synthetic surface that resembles grass, and bars HOAs from banning low-water landscaping as a turf replacement. So a resident in an HOA community generally cannot be forced to keep natural grass instead of compliant synthetic turf.
