Placentia, CA Public Conduct: Public Marijuana Use (2026)

Placentia Municipal Code § 8.42.040(c) declares that all marijuana related use and activity is prohibited in the city of Placentia. The definition in § 8.42.030 sweeps in dispensing, cultivation, possession, manufacture, transporting, delivery, distribution, and sale, whether for a marijuana business, "for personal use or otherwise." Section 8.42.020 states that the chapter applies to all property, public and private, and applies indoors and outdoors. Section 8.42.010(c) directs that any unclear provision be read in the manner most prohibitive of marijuana related use and activity, to the extent consistent with applicable law.

The chapter leaves room for state law. Section 8.42.040(a) permits indoor cultivation for personal use by persons 21 or older on the grounds of a private residence only to the extent state law allows, and bars all outdoor cultivation in the city. Section 8.42.010(a) exempts qualified patients and identification card holders who cultivate indoors, possess, and use marijuana for their own personal medical purposes to the degree state law authorizes. Section 8.42.020(d) adds that nothing in the chapter authorizes criminal prosecution or abatement inconsistent with Kirby v. County of Fresno, 242 Cal. App. 4th 940 (2015).

The provision that speaks most directly to smoking in public is Chapter 8.28. Section 8.28.030 bars smoking marijuana or marijuana products in any area the city has posted as no smoking, including Civic Center Plaza at 401-411 E. Chapman Avenue, a civic center, parks and the first 50 feet beyond a park perimeter, and public facilities. Section 8.28.040 bars discarding marijuana products in those areas, and § 8.28.050 lets any city employee authorized to enforce the code or state law enforce the chapter. Sidewalk vendors (§ 8.10.110) and food trucks (§ 13.50.040) are also barred from selling marijuana.
