Title 18 — Zoning

Chapter 18.194 — MARIJUANA AND MEDICAL MARIJUANA

San Dimas Zoning Code · 2026-06 edition · updated 2026-07-06 · San Dimas

§ 18.194.010. Purpose.

The purpose and intent of this chapter is to prohibit marijuana and medical marijuana dispensaries, cultivation of marijuana and medical marijuana, and the mobile delivery of same within the city limits. It is recognized that it is a federal violation under the Controlled Substances Act and is classified as a "Schedule I Drug" which is defined as a drug or other substance that has a high potential for abuse. Furthermore, the Federal Controlled Substance Act makes it unlawful for any person to cultivate, or dispense marijuana. The Controlled Substance Act contains no statutory exemption for the possession of marijuana for medical purposes.

In addition the prohibition of marijuana and medical marijuana dispensaries, cultivation of marijuana and medical marijuana and the mobile delivery of same within the city limits will help protect the public health, safety and general welfare of the city and its residents. Additionally, there is evidence of an increased incidence of crime-related secondary impacts in locations associated with marijuana and medical marijuana dispensaries, cultivation of marijuana and medical marijuana and the mobile delivery of same which is contrary to policies that are intended to promote and maintain the public's health, safety and welfare. This chapter will help preserve the city's law enforcement services, in that monitoring and addressing the negative secondary effects and adverse impacts will likely burden the city's law enforcement resources.
