How to Start a Cannabis Grow in Michigan: Class A, B and C Grower Licenses

If you want to grow cannabis for sale in Michigan, the grower license is the part that matters. Filing your business entity with the state is a separate step, and it does not give you permission to grow anything. This guide covers how to start a cannabis grower business in Michigan, from choosing a license class to the filings and approvals that come before your first plant.

Informational content, not legal or tax advice. Cannabis rules and agency procedures change, and the figures below are the ones we could verify. Before you sign a lease or file anything, talk to a Michigan attorney who handles cannabis licensing and a CPA who works with cannabis businesses.

What You Need Before You Start

Gather these items before you commit money to a property or equipment:

• A business plan that states your license class, plant count, facility size and intended buyers
• A lease or purchase agreement for a property you have confirmed is zoned for cultivation
• Written zoning confirmation from the city, village or township, plus any certificate of occupancy and health approvals the local government requires
• A site plan and floor plan showing canopy space, security features and entry points
• Your entity documents, such as Articles of Organization for an LLC
• A Michigan resident agent and registered office
• Funds for the $3,000 nonrefundable prequalification fee and the license fee for your class
• A federal employer identification number from the IRS, which you will need for banking and payroll

Step 1: Pick Your License Class and Plant Count

Michigan's adult-use grower licenses are sized by plant count. The initial fee and the renewal fee are the same for each class.

Class	Plant limit	Initial fee	Renewal fee
Class A	Up to 100 plants	$1,200	$1,200
Class B	Up to 500 plants	$6,000	$6,000
Class C	Up to 2,000 plants	$24,000	$24,000
Excess Grower	Up to 2,000 plants, depending on the licensee's medical plant allowance	$24,000	$24,000

Medical grower classes under the Medical Marihuana Facilities Licensing Act use different plant counts, and the home grow rules for caregivers and patients are a separate regime. Do not mix them into your adult-use plan.

Choose the class your facility and buyers can support, not the biggest number you can imagine. The license fee is only one cost. Build-out, security, power and staffing will likely be larger line items in your budget.

Step 2: Check the Municipality Before Anything Else

This is the step most new growers get wrong. Local rules can block your project before the state ever reviews it.

• Ordinance check: A municipal ordinance prohibiting adult-use establishments blocks growers as well as retailers. Ask whether your city, village or township has one.
• Local fees and zoning: A municipality may charge up to $5,000 a year and may set its own zoning rules for grow facilities.
• School buffer: A 1,000-foot school buffer applies unless the local government reduces it. Ask how the distance is measured and get the answer in writing.

Michigan has 83 counties, about 275 to 280 cities, about 255 to 258 villages and 1,240 townships. Your property sits in one of those local governments, and that government controls the zoning. Call the planning or zoning office, ask your questions in writing, and keep the reply in your file. Do not sign a lease until you have it.

Step 3: Form the Business Entity

You have three common choices. Each one has its own filing, and none of them is a cannabis license.

• Sole proprietorship or general partnership: No LARA filing is required. You file an assumed name certificate with the county clerk in each county where you do business.
• Limited liability company (LLC): File Articles of Organization (Form CSCL/CD-700) with a $50 filing fee. The name must include "Limited Liability Company," "L.L.C." or "L.C." You must name a resident agent and a registered office. A P.O. box alone is not enough for the registered office. The yearly filing is an Annual Statement (Form CSCL/CD-2700) with a $25 fee, due February 15, beginning the year after formation.
• Corporation: File Articles of Incorporation for Profit Corporation (Form CSCL/CD-500) with a $60 filing fee. The yearly filing is an Annual Report (Form CSCL/CD-2500) with a $25 fee, due May 15. Late fees start at $35 for May 16 to May 31 and reach a $75 maximum on or after September 1.

Michigan has no franchise tax. A standard LLC is a pass-through entity, so its members report the income on their Michigan individual income tax at the flat 4.25% rate for the 2026 tax year. An LLC that elects federal C corporation treatment is subject to the 6% Michigan Corporate Income Tax. Michigan also offers an elective Flow-Through Entity Tax. Ask your CPA which structure fits your plan.

Search your name on the MiBusiness Registry business search before you file. You can reserve a name with Form CSCL/CD-540 for $25, and the reservation lasts six months following the month of filing. File through the MiBusiness Registry Portal. If you need speed, LARA offers expedited service: $50 for a 24-hour review of a formation document, $100 for same-day review, $500 for two-hour review (received by 3 p.m.) and $1,000 for one-hour review (received by 4 p.m.). These fees are added to the filing fee.

Filing an entity is a filing, not a license. LARA's Corporations Division receives and files entity documents, and it does not license businesses. Your grower license comes from the Cannabis Regulatory Agency, which you reach through michigan.gov.

Step 4: Prequalify and Apply for the License

Michigan requires a $3,000 nonrefundable prequalification fee. Treat it as money you will not get back, even if your application is later denied.

1. Confirm the steps with the Cannabis Regulatory Agency. Ask what the prequalification review covers, whether it must be completed before the full license application, and how long each stage takes. No standard processing time is stated here, so do not plan around one until the agency confirms it.
2. Prepare ownership and background disclosures. Expect to identify everyone with an ownership or control interest in the business. Confirm the full list with the agency.
3. Submit the license application and pay the fee for your class. Use the table above. The renewal fee matches the initial fee, so budget for it in every year you plan to operate. Confirm the renewal schedule with the agency.

Keep copies of everything you submit, along with proof of payment and the agency's written responses.

Step 5: Lock Down the Property and Local Approvals

Once the zoning answer is in writing, work through the property requirements in this order:

1. Zoning letter in hand before the lease. Make the lease contingent on the zoning answer and on your license approval if you can.
2. Certificate of occupancy. Your local building department decides whether the space is safe for the use you are proposing. Ask what inspections it requires before you open.
3. Licensed trade contractors. Electrical, plumbing and mechanical work must be done by properly licensed contractors. The LARA Bureau of Construction Codes handles trade licensing, so confirm the license types that match your scope of work with the bureau.
4. Health approvals. Check with your local health department about any approvals that apply to your building or water supply.
5. Agriculture rules. Check with the Michigan Department of Agriculture and Rural Development (MDARD) about whether any of its rules apply to your cultivation operation.

Step 6: Set Up Your Michigan Tax Registrations

Michigan has no single general statewide business license. Licensing happens by trade or activity, and the cannabis grower license is one of those activity licenses. Your tax setup is separate.

• Sales tax: The Michigan Department of Treasury offers a sales tax registration that is free. Whether you need one depends on how your sales are structured, so confirm this with Treasury before your first sale. Online registration is available at Treasury's online business registration page. For retailers, the sales tax license can arrive in as little as 7 business days.
• Income tax: Your entity type decides which Michigan income tax applies to you, as described in Step 3.
• City income tax: Only 24 Michigan cities levy a city income tax. Check whether your city is one of them.
• Federal tax: Federal tax rules for cannabis businesses are complicated and have caught many operators off guard. Ask your CPA how they apply to your structure before you set your prices.

Step 7: Build, Document and Operate

Build exactly to the site plan the agency and the local government approved. Changes after approval can trigger new reviews, so ask before you move a wall or a security camera.

Track your plant count from day one. Your class sets a ceiling, and exceeding it is a compliance problem, not a rounding error. Keep your inventory records, security logs and sales records in a format you can produce quickly if the agency asks. Follow the conditions written into your license.

Common Mistakes to Avoid

• Signing a lease before the zoning answer. A municipal ban or buffer problem can strand a build-out you have already paid for.
• Treating the LARA filing as your license. An approved Articles of Organization does not let you grow a single plant.
• Ignoring the 1,000-foot school buffer. Measure it yourself, then confirm the method with the local government.
• Using a P.O. box as your registered office. A P.O. box alone does not meet the requirement. Use the physical location of your resident agent.
• Choosing a class that does not fit the facility. A Class C plan in a space built for Class A will cost more to fix than to plan correctly.
• Missing the annual filings. An LLC's Annual Statement is due February 15, and a corporation's Annual Report is due May 15. Put both on your calendar on day one.
• Mixing up the regimes. Medical grower classes, adult-use grower classes and home grow rules have different plant counts and rules. Read the rules for the license you actually hold.
• Skipping the CPA. Cannabis tax treatment is not the same as ordinary small business tax treatment.

Expected Results and What We Can and Cannot Promise

A well-planned grow may produce consistent harvests, and a well-run business may build relationships with buyers over time. No one can promise a yield, a product quality level, a timeline or a profit figure, and this article does not make any of those promises. Treat any yield numbers in your plan as estimates that depend on your strain, lighting, climate control and operating skill.

Be careful with what you say about the product. Cannabis is not an FDA-approved drug, and the FDA treats claims that a cannabis product treats, cures or prevents a disease as drug claims. Keep your marketing and any product language to what the regulator allows, and have counsel review it before publication.

Next Steps and Official Resources

• LARA Corporations Division: entity filing forms and guidance
• MiBusiness Registry Portal: online entity filings
• Michigan Department of Treasury: tax registrations and rates
• Cannabis Regulatory Agency: grower license, prequalification and renewal information, found on michigan.gov
• Michigan Small Business Development Center: free business planning help
• SBA Michigan District Office: federal small business resources for Michigan

Start with the zoning answer, then the entity, then the license. If you do those three things in order and in writing, you will avoid most of the expensive mistakes new Michigan growers make. For anything that touches your specific facts, confirm the answer with the agency or with a qualified professional before you act on it.
