1. Do I need a permit or license?

All cannabis-related businesses are required to obtain a 420 License to operate inside city limits. A cannabis related business is one that participates in the commercial cultivation, extraction, sale, testing, processing (including harvesting and curing), or manufacture of marijuana products intended for consumption by others.  Please be aware, commercial cannabis related businesses are not permitted in residential homes with the exception of medical marijuana delivery-only businesses (no sales) which are allowed as a home-based business. 

For information on plant limits for personal consumption please contact the State of Montana - Cannabis Control Division. 
Note: The city does not distinguish between medical and recreational cultivation, sales, manufacturing etc. 

2. How do I apply for a permit/license?

Starting XXXX date, all cannabis related businesses will be required to have an active '420 license'. You will be able to apply online by logging into the Citizen Access Portal after XXXXX date. We encourage you to apply as soon as possible after XXXX to allow staff sufficient review time and so as not to impact your business in any way.

3. How does the review process work?

4. How long does it take to get a 420 license/ commercial building permit issued?

Generally a complete application, where no revisions are required, will take approximately 6-8 weeks to complete the review process. Once issued, it is up to the applicant to schedule and pass their final inspections.

5. Will I need a change-of-use?

A change-of-use permit is a commercial building permit that changes the use of an existing building or tenant space from one approved use/occupancy classification to another as described in the International Building Code. It compares the code requirements of the existing use to the requirements of the proposed use and demonstrates how the building or tenant space meets the code requirements for the new use – any code deficiencies will need to be corrected prior to occupying the space/changing the use.

A change-of-use is required for all commercial cultivation and extraction facilities even if the last approved use of the space was the same. This is because the operations and intensity of each individual facility or business owner vary and there may be an increase or decrease in canopy size or the Max Allowable Quantity (M.A.Q.) of solvents or combustible fibers (drying/processing) in each control area etc. 

When will the Building Department NOT require a change-of-use to obtain a 420 license?
Please be aware, a change-of-use permit is required in almost all situations except for dispensaries moving into a space most recently permitted as a retail location (Mercantile Occupancy – M.) 

6. Will I need an Architect/Engineer?

A licensed professional architect or engineer is required for commercial projects and is required to stamp a change-of-use.

7. Will I need mechanical, electrical or plumbing permits?

Permits shall be purchased for all work associated with the new use/occupancy and commercial buildings require licensed electricians and plumbers to complete the work. Below is a list of additional permits commonly required for cannabis facilities.

• Electrical Permit: Dedicated outlets are needed for all mounted light fixtures, fans etc. (extension cords are not allowed for permanent fixtures.) Additionally, increased lighting/mechanical loads may require increasing the size of the electrical panel/breaker/service.
• Mechanical Permit: New exhaust fans shall be installed and exhausted to an approved location per the currently adopted IMC. To prevent noxious odors, we recommend using a carbon filter or other odor mitigation on your exhaust air.
• Plumbing Permit: Where cultivation occurs, the building shall be equipped with an approved backflow prevention device on the service line. If you are using a hose or faucet to water the plants, it shall also be equipped with an approved backflow prevention device.

8. Can I install mechanical equipment, duct work, or exhaust fans myself?

Mechanical permits are required when vents and ducts are added, replaced, or relocated. This includes dryer vents, exhaust fans, range hood vents and extending heating ducts, adding registers, replacing furnaces and air conditioning units. A building owner can self-perform this work however they will still be required to pull a permit and pass all the necessary inspections. We strongly recommend you hire a professional as they will be familiar with the code requirements as well as how to identify and protect penetrations through rated assemblies in accordance with the code.

9. I have un-permitted work I need to resolve in order to get my license, now what?

For whatever reason, it happened and now you want to make it right! While we cannot make exceptions to the code, we will do our best to work with you in bringing the un-permitted work back into compliance. You will need to apply for all applicable permits related to the unpermitted work and the permits will be reviewed/inspected as if they were new. It will be the responsibility of the applicant to demonstrate code compliance and that may include exposing previously covered work for the inspection(s) or providing plans to obtain a permit.

10. How do I open a dispensary?

You will need to apply for a 420 License to open a dispensary in the City of Missoula. When choosing a business location for your dispensary (M - occupancy), we recommend trying to find a tenant space previously used as a retail store (M - occupancy) with a current City of Missoula business license. If dispensing is your only cannabis-related activity and you move into a space where the most recent approved use/occupancy classification was a retail store (M - occupancy), you will not be required to complete a change-of-use. You should also check with the Planning Department to verify if your use type will be allowed at your proposed location. Please also note, the State of Montana - Cannabis Control Division will require a copy of your issued 420 license as part of their review process.
