Summary
Thousand Oaks bans irrigating purely ornamental turf on commercial, industrial and institutional properties under TOMC § 10-2.1104(l). Non-functional grass irrigation on CII sites is prohibited outright, and an owner who wants to keep watering ornamental turf must apply to the water purveyor for a functional-turf waiver. Turf shown on filed CII landscape plans can instead be swapped for mulch or other permeable, climate-appropriate ground cover.
(l) Non-functional turf: Irrigation of non-functional grass on CH properties is prohibited. Designation of turf as functional on CH properties in order to irrigate requires application and approval of a waiver by the water purveyor. Areas designated as turf on CII landscape plans filed with the City may be replaced with alternative climate-appropriate landscaping including mulch, or other permeable ground cover.

Full Breakdown
The rule sits in Article 11 of Chapter 2, Thousand Oaks' water conservation ordinance (Ord. 1705-NS, effective November 25, 2022). 1104(l) targets 'non-functional turf,' defined in Sec. 1101(k) as turf that is ornamental and not regularly used for recreation, civic events, or community gatherings, on CII properties (commercial, industrial and institutional, per Sec. 1101(b)). Irrigating that kind of grass is flatly prohibited; subsection (l) itself carries no seasonal exception. An owner who believes turf on a CII site is actually 'functional' (used for recreation or events) can only keep watering it by filing an application with the water purveyor and getting the turf reclassified through an approved waiver; without that waiver, watering the grass is a permanent-measure violation.
Owners who do not want a waiver may instead replace CII turf shown on their filed landscape plans with 'alternative climate-appropriate landscaping,' which the ordinance lists as including mulch or other permeable ground cover, tying back to the Article 11 definition of climate-appropriate plants as species suited to the region's rainfall pattern in Sec. 1101(c). 1109 that only activate once the City Council declares a shortage tier.
Violations & Fines
Sec. 10-2.1103 makes any Article 11 violation, including unauthorized non-functional turf irrigation, prosecutable under Title 1, Chapter 2, Articles 1 and 2, with each day of continued watering a separate offense, and it also brands the violation a public nuisance under Sec. 1-6.01. The water purveyor enforces first; if it fails to act, the City steps in. Repeat violations can bring a mandatory flow restrictor, and continued willful violations can lead to service disconnection, both billed to the property owner.
