Rancho Cucamonga Says No to Marijuana Businesses

As state laws surrounding marijuana change, local regulations are now set.

Recent changes in California law are raising the same question in cities across California: can a marijuana business operate here? The answer in our community is no. All marijuana/cannabis businesses are illegal in Rancho Cucamonga. This includes all medical and recreational stores, delivery services, commercial growing, product manufacturing, and testing labs.

The Bureau of Cannabis Cultivation is aware of the ban and will not issue state licenses to operate in Rancho Cucamonga. Any cannabis business opened here will be shut down immediately and the owners/operators will be prosecuted.

Here are answers to some frequently asked questions about cannabis:

Are there any cannabis businesses I can do from my home?
No. All cannabis businesses are illegal in Rancho Cucamonga.

Can I grow marijuana for my personal use?
State law and Rancho Cucamonga's Municipal Code allow cultivation of six or fewer plants per home for personal use. Plants must be grown indoors; outdoor growing is illegal. Please check with the Building and Safety Department regarding any changes to your plumbing and/or electrical systems to support an indoor growing space. You can make an appointment by calling the Building and Safety Department at (909) 477-2710.

Where can I smoke marijuana?
State law allows personal use on your private property. At home, use is permitted in your backyard if it is not visible from the street or any other public place. Using cannabis in a public place, such as a public sidewalk or on a restaurant patio, or anywhere visible to the public, front yard, apartment patio or balcony, is against the law. If you rent and/or have an HOA, you must contact them for further regulations.

Can I have marijuana delivered to me?
No. It is illegal to have cannabis delivered to any home or business in Rancho Cucamonga.
