Pleasanton, CA Landscaping Rules: Water Restrictions (2026)

Pleasanton's drinking water is wholesaled by the Zone 7 Water Agency, and the city administers outdoor water-use restrictions through its Water Conservation Program and Municipal Code Chapter on water conservation/drought contingency. Standard restrictions direct customers to water lawns and ornamental landscaping only between 9 p.m. and 6 a.m. to reduce evaporation and wind loss; hand watering with a shut-off nozzle and drip irrigation are generally allowed at other hours. Watering outdoors is prohibited during and within 48 hours of measurable rainfall. The city also advises limiting outdoor watering to no more than one day per week between October and March, with a recommended year-round irrigation schedule available. Potable water may not be used for power washing of driveways, sidewalks, or other hardscapes, and customers must eliminate irrigation runoff by shortening run times and using multiple shorter cycles. During declared droughts, Zone 7 and the Tri-Valley agencies have imposed stricter mandatory measures - for example, limiting irrigation to no more than three non-consecutive days per week March through October and one day per week November through February, with required leak repairs. The specific day limits in effect vary with the declared drought stage, so customers should check PleasantonWaterConservation.com for current rules. Note that California's AB 1572 also separately bans irrigating non-functional turf with potable water at commercial, institutional, industrial, and HOA-common-area properties (phasing in through 2027-2029).
