Placentia, CA Cannabis Regulations: Dispensary Zoning (2026)

No zone in the City of Placentia accepts a dispensary application, because the City Council wrote the ban into two parts of the code. Chapter 8.42 of the Placentia Municipal Code, adopted by Ordinance O-2017-03, prohibits marijuana-related use and activity for recreational, medical or any other use. Section 8.42.030 defines a dispensary as any location where marijuana or devices for its use are offered, and the definition includes retail sales, delivery services, mobile dispensing and distribution. A storefront, a delivery operation and a mobile unit all fall inside that definition. Chapter 23.46 of the Zoning Code adds, in § 23.46.040, that marijuana-related uses and activities are prohibited on all parcels in the city, so a zoning application has nothing to approve.

The ban has narrow carve-outs. Licensed marijuana transporters are permitted to pass through the city on public roads, as Business and Professions Code Sections 19338 and 26080 mandate. Adults 21 years of age or older can cultivate indoors for personal use on the grounds of a private residence, but only to the extent state law allows, and all outdoor cultivation is prohibited. Section 8.42.010 also states that nothing in the chapter authorizes qualified patients to engage in the collective cultivation described in Health and Safety Code Section 11362.775, and it directs that any unclear provision be interpreted in the manner most prohibitive of marijuana-related use and activity, to the extent consistent with applicable law.

Chapter 8.42 applies to all property, public and private, and applies indoors and outdoors (§ 8.42.020). Subsection (d) of that section adds that nothing in the chapter authorizes criminal prosecution or abatement inconsistent with Kirby v. County of Fresno, 242 Cal. App. 4th 940 (2015). Section 8.42.010 carves out state-preempted activity: the prohibition applies except when preempted by state law.
