What licenses does Maine issue?
Maine's Office of Cannabis Policy issues adult-use licenses in six categories under 28-B M.R.S. Chapter 1: Tier 1–4 Cultivation Facilities, Nursery Cultivation Facility, Products Manufacturing Facility, Cannabis Store (retail), Testing Facility, and Sample Collector. Fees are set by 28-B M.R.S. §207 and range from a $60 nursery application fee to a $30,000 Tier 4 indoor cultivation annual fee.
Maine's adult-use cannabis framework authorizes the OCP to issue the following establishment licenses. Each category has its own application fee, annual license fee, and operational rules. Most businesses hold one primary license and may add endorsements or additional licenses as they grow.
Maine cannabis license types and fees
The table below reflects the fee schedule in 28-B M.R.S. §207 and the OCP's published fee guidance. Cultivation fees are tiered by canopy size and differ for outdoor versus indoor (or mixed) operations. These are state fees only; municipalities may add local licensing fees and taxes.
| License Type | Application Fee | Annual License Fee | What It Authorizes |
|---|---|---|---|
| Tier 1 Cultivation | $100 | Plant-count-based: up to $9/mature plant (outdoor) / up to $17/mature plant (indoor). Plant-canopy-based: up to $250 (outdoor) / up to $500 (indoor) per §207 — note OCP's published FAQ table lists the Tier 1 plant-canopy fee as $500 outdoor with no indoor canopy tier; confirm the current figure with OCP. | Smallest canopy — up to 30 mature plants or up to 500 sq ft canopy |
| Tier 2 Cultivation | $500 | $1,500 (outdoor) / $3,000 (indoor) | Mid-size cultivation canopy |
| Tier 3 Cultivation | $500 | $5,000 (outdoor) / $10,000 (indoor) | Larger cultivation canopy |
| Tier 4 Cultivation | $500 | $15,000 (outdoor) / $30,000 (indoor) | Largest cultivation canopy |
| Nursery Cultivation | $60 | $350 | Clones, seedlings, immature plants for sale to cultivators |
| Products Manufacturing | $250 | $2,500 | Edibles, concentrates, topicals, other manufactured products |
| Cannabis Store (Retail) | $250 | up to $2,500 | Adult-use retail sales to consumers 21+ |
| Testing Facility | $250 | $1,000 | Independent compliance laboratory testing |
| Sample Collector | $100 | $250 | Collection of cannabis samples for testing |
For cultivation, §207 also provides for an additional fee when a licensee increases canopy size. The exact tier canopy limits and the plant-count versus plant-canopy election are defined in 28-B M.R.S. §301; confirm the current canopy thresholds with OCP before selecting a tier.

How the licensing process works
Maine cannabis licensing is a two-track process: you must secure municipal authorization from your host town AND obtain a state OCP license. The state license progresses from conditional (initial approval, 12 months, before your facility is built) to active (after your facility passes OCP's pre-operation inspection). End-to-end timelines commonly run 10–18 months, driven largely by municipal approval.
- Form a Maine business entity with the Secretary of State and designate a registered agent.
- Secure municipal authorization — Maine is an opt-in system; your town must affirmatively allow cannabis businesses, and you need written local approval for your specific site.
- Submit the OCP application through the OCP portal with the application fee, ownership disclosures, source-of-funds documentation, facility plan, and security plan.
- Pass background checks on all qualifying principals and managing employees (OCP Form 4).
- Receive a conditional license after OCP's initial review (valid 12 months).
- Build out and pass the pre-operation inspection, then convert to an active license to begin operations.

Medical versus adult-use licensing
Maine operates two parallel cannabis programs: the adult-use market regulated under Title 28-B and a separate medical program. The OCP administers both. A retail business can serve both markets with the appropriate adult-use license and medical endorsement. Medical licensing, caregiver registration, and patient rules are governed separately — see the Maine Cannabis Regulations guide for the current framework and the medical program rules.
Frequently asked questions
What types of cannabis licenses does Maine issue?
Maine's Office of Cannabis Policy (OCP) issues adult-use licenses under 28-B M.R.S. Chapter 1 in these categories: Tier 1–4 Cultivation Facilities (tiered by canopy size), Nursery Cultivation Facility, Products Manufacturing Facility, Cannabis Store (adult-use retail), Testing Facility, and Sample Collector. Maine also runs a separate medical program with its own licensing. Most businesses hold one primary license and may add endorsements or additional licenses as they grow.
How much does a Maine cannabis license cost?
Fees are set by 28-B M.R.S. §207. Application fees range from $60 (nursery) to $500 (Tier 2–4 cultivation). Annual license fees range from $250 (sample collector) to $30,000 (Tier 4 indoor cultivation). A Cannabis Store (retail) pays a $250 application fee and up to $2,500 annually. A Products Manufacturing Facility pays $250 to apply and $2,500 annually. A Testing Facility pays $250 to apply and $1,000 annually. These are state fees only; municipalities may add local licensing fees.
Does Maine require residency to get a cannabis license?
No. Maine has no residency requirement for cannabis license applicants. Out-of-state individuals and entities may apply. However, the applicant must register a business entity with the Maine Secretary of State and maintain a registered agent in Maine. All principals with a sufficient ownership interest must pass OCP background checks regardless of state of residence.
How long does it take to get a Maine cannabis license?
For a complete application, OCP review typically runs 60–120 days. The end-to-end timeline — including municipal authorization, application preparation, OCP review, and pre-operation inspection — commonly runs 10–18 months for a retail store, largely because municipal approval timelines vary widely by town. Cultivation and manufacturing timelines follow a similar pattern but depend on facility build-out.
What is the difference between a conditional and an active license?
A conditional license is OCP's first approval, granted after your application passes initial review. It is valid for 12 months and is the only license you can hold before your facility is built and inspected. An active license is granted after your facility passes OCP's pre-operation inspection. You must hold an active license to legally operate. See the Maine Cannabis Conditional License guide for the full progression.
Can one business hold multiple Maine cannabis licenses?
Yes, Maine permits vertical integration and multiple license holdings subject to statutory limits and OCP rules. A single entity may, for example, hold both a cultivation and a manufacturing license, or a retail license with a medical endorsement. Ownership caps and control restrictions apply to certain license combinations; consult OCP rules and qualified counsel before structuring a multi-license operation.
Where do I apply for a Maine cannabis license?
Applications are submitted through the Office of Cannabis Policy (OCP) portal at maine.gov/dafs/ocp. OCP is a division of the Department of Administrative and Financial Services and administers both the adult-use and medical cannabis programs. You must secure municipal authorization for your proposed location before OCP will process your application.
