Thousand Oaks has 3 specific rules on the books covering different aspects of water use rules, and some of them might surprise you.

Lawn Watering Restrictions

Thousand Oaks follows Calleguas Municipal Water District and Las Virgenes MWD restrictions limiting outdoor irrigation to assigned days and restricting watering to before 9 a.m. or after 6 p.m.

Key details: Wholesaler: Calleguas MWD. Watering hours: Before 9 a.m. or after 6 p.m.. Assigned days: By address during drought. Runoff: Prohibited year-round.

Compared to other cities, Thousand Oaks takes a harder line on lawn watering restrictions. The enforcement and penalty structure reflects that.
