Oxnard, CA Landscaping Rules: Weed Ordinances (2026)

4 of the Oxnard Property Maintenance Code (OPMC), adopted by Ordinance No. " The rule targets grasses, annual plants and general vegetation; it expressly carves out cultivated flowers and gardens, so ornamental beds are not swept up in the cap even if individual plants exceed a foot. Noxious weeds are separately banned outright, with no height threshold. 1. When an inspector documents overgrowth past 12 inches, the owner or agent in charge of the property receives a notice of violation. 3, and separately lets any duly authorized city employee enter the property, cut and destroy the weeds, and charge the removal cost to the responsible owner or agent.

This sits alongside the older nuisance-abatement scheme in Chapter 7 of the city code, which independently declares weeds that grow tall, dry and fire-prone, or otherwise noxious or dangerous, a nuisance subject to the city manager's abatement notice-and-lien process. Between the two provisions, Oxnard has both a bright-line numeric trigger (12 inches) under the Property Maintenance Code and a fire-hazard/nuisance trigger under Chapter 7 for hazardous growth regardless of height.
