Title 17 — ZONING

Chapter 17.114 — MARIJUANA CULTIVATION

Folsom Municipal Code · 2026-09 edition · updated 2026-10-02 · Folsom

§ 17.114.010. Purpose and intent.

The city council finds as follows:

A. Purpose. The purpose and intent of this chapter is to regulate the cultivation of marijuana
in a manner that protects the health, safety and welfare of the community consistent with
Proposition 64, also known as the Control, Regulate, and Tax Adult Use of Marijuana Act
(“AUMA”). This chapter is not intended to interfere with a patient’s right to medical
marijuana, as provided for in California Health and Safety Code Section 11362.5, nor does
it criminalize medical marijuana possession or cultivation by specifically defined
classifications of persons, pursuant to state law. This chapter is not intended to give any
person unfettered legal authority to grow marijuana; it is intended simply to impose zoning
restrictions on the personal indoor cultivation of marijuana permitted under AUMA when
it is authorized by California state law for medical or other lawful purposes under the state
law.

B. Applicability. As authorized by AB 243 (Section 11362.777 of the Health and Safety
Code), marijuana cultivation as defined in Section 17.114.020, whether indoor or outdoor,
remains prohibited in all zones and districts of the city of Folsom until and unless AUMA
is passed at the November 8, 2016, statewide general election. Upon the passage of AUMA
at said election, the cultivation of marijuana in the city shall be controlled and regulated by
the provisions of this chapter.

C. Nonconflicting Enactment. No part of this chapter shall be deemed to conflict with federal
law as contained in the Controlled Substances Act, 21 U.S.C. Section 800 et seq., nor to
otherwise permit any activity that is prohibited under that Act or any other local, state or
federal law, statute, rule or regulation.
