Yuba County, CA Landscaping Rules: Water Restrictions (2026)

Unincorporated Yuba County is served by a patchwork of water suppliers and irrigation districts rather than one county water utility, so specific watering-day limits, hours, and runoff rules are set by the relevant provider, not by a uniform County ordinance. Over-arching restrictions come from the State. The State Water Resources Control Board adopts statewide emergency conservation regulations during droughts that prohibit wasteful practices such as letting irrigation water run off onto pavement, hosing down driveways with potable water, and irrigating ornamental turf within a set period after rain. California's longer-term framework (the Making Conservation a California Way of Life rules) also directs urban water suppliers toward efficiency standards. The County's 2030 General Plan reinforces conservation: Policy NR12.5 requires new developments to use climate-appropriate landscaping to the maximum extent feasible, Policy NR12.6 requires water-conservation technologies in accordance with state law, and Policy NR12.4 encourages using recycled and untreated irrigation-district water for outdoor irrigation. Rural homeowners on private wells are not metered by a provider, but remain subject to statewide prohibitions on water waste and to groundwater-management considerations.
