Placentia, CA Landscaping Rules: Weed Ordinances (2026)

The six inch limit sits in Placentia's local amendments to the International Property Maintenance Code, adopted at Municipal Code § 20.54.050 and renamed the Property Maintenance Code of the City of Placentia. Section 302.4 as amended says premises and exterior property "shall be maintained free from weeds or plant growth in excess of six (6) inches" and that noxious weeds are prohibited. The amendment defines weeds as all grasses, annual plants, and vegetation other than trees or shrubs, and carves out cultivated flowers and gardens, so a tended garden bed is not a violation while a lawn gone to seed is. The Development Services Department is the code official that implements and enforces the property maintenance code under amended § 103.1.

When an owner or agent fails to cut and destroy weeds after service of a notice of violation, the owner is subject to prosecution under Section 109.3 of the property maintenance code. If the owner still does not comply, a duly authorized city employee or a contractor hired by the city is authorized to enter the property, cut and destroy the weeds, and the owner or agent responsible for the property pays the cost.

A second, older track sits in Chapter 8.08. Section 8.08.060 requires every owner, occupant, and person in control of land to abate dry grass, Russian thistle (tumbleweeds), noxious weeds, and other vegetation that is a fire, health, or safety hazard, including along adjoining sidewalks and parkways. The weed abatement officer posts a notice giving 30 days to comply (§ 8.08.070), and the city's administration charge on abatement work is 35% of the contractor's cost, never less than $50 (§ 8.08.130). Overgrown vegetation including dead trees and weeds is also a listed public nuisance condition at § 8.06.030.
