Adult-Use Cannabis Cultivation Facility for Sale in South Portland, Maine

This is a compelling opportunity to acquire a Tier 3 Adult-Use cannabis cultivation facility in South Portland, Maine, complete with an established wholesale account book and a rapidly growing presence across the state. Since its first harvest in May 2024, the business has quickly scaled operations and distribution, generating approximately $1.87M in 2025 revenue and securing shelf space in the majority of licensed retail stores throughout Maine.

The facility spans 11,100 sq ft, with 3,250 sq ft of dedicated cultivation space, and is built out as a state-of-the-art, best-in-class grow operation. The cultivation layout includes four flower rooms, one mother room, and one veg room, supported by recently installed modern lighting and dozens of new genetics. The operation is powered by robust infrastructure, including 1200 amps of 480V and 120/208V three-phase power, ensuring efficiency, scalability, and reliability.

Investment Highlights:

Total investment including capex and carry exceeds $5M, with approximately $3M in capex alone spent to make this facility truly standout.

Maine continues to be an attractive cannabis market with strong wholesale demand and a growing adult-use sector. This business is well-positioned to capitalize on that demand thanks to its respected brand reputation, premium flower quality, and expanding operational capabilities.

The company has submitted an application for a manufacturing license, offering additional upside through vertical expansion and value-added product lines.

A 12-month option to purchase the building from the landlord provides a potential path to real estate ownership and long-term cost control for a qualified buyer.
