Building Cannabis Facilities Under Ohio's Adult-Use Market
Ohio voters approved adult-use cannabis in 2023, and the state now runs medical and adult-use programs through the Division of Cannabis Control within the Ohio Department of Commerce. With a large in-state market and cultivators licensed to expand canopy (Level I operators up to 100,000 SF and Level II operators up to 15,000 SF under current rules), Central Ohio operators are expanding, converting buildings, and building new cultivation and processing space.
Cannabis buildings are process facilities. Flower and veg rooms need cleanable, airtight envelopes, precise temperature and humidity control, heavy electrical service for lighting and cooling, odor control, irrigation, and security that satisfies state rules. TCG self-performs the insulated metal panel grow room envelope, delivers specialty polyaspartic floors through a 10-year cannabis flooring partnership, and designs HVAC, dehumidification, and power with in-house MEP engineers under one design-build contract.
Site selection comes first. Operators must stay 500 feet from schools, churches, public libraries, playgrounds, and parks, and each Central Ohio municipality sets its own zoning, so TCG confirms eligibility, AEP Ohio power capacity, and building suitability in preconstruction before you commit. Read our cannabis facility requirements guide and value-engineering guide.
Columbus Cannabis Facility Capabilities
From a single flower room expansion to a ground-up cultivation and processing campus.
Indoor Cultivation
Flower, veg, mother, and clone rooms with IMP envelopes, LED lighting, fertigation, and room-by-room climate control.
Processing & Extraction Labs
C1D1 and C1D2 extraction rooms, post-processing, packaging, and vaults with ventilation, fire protection, and hazardous-use code compliance.
Cultivation HVAC & Power
Dehumidification, cooling, and electrical services sized by our MEP engineering team to canopy, lighting load, and transpiration.
Greenhouse & Mixed-Light
Greenhouse and hybrid facilities with blackout, supplemental lighting, and envelope upgrades, see our CEA construction page.
Building Conversions
Industrial and flex buildings converted to cultivation, often faster and cheaper than ground-up when power and structure allow.
Dispensaries
Retail dispensaries with secure vaults, check-in, and customer-facing finishes, see our dispensary buildout cost guide.
What Cannabis Facility Construction Costs in Columbus (2026)
Columbus cannabis pricing: indoor cultivation buildout $180-$350/SF, ground-up indoor cultivation $300-$550/SF, processing and extraction $250-$500/SF, greenhouse and mixed-light $60-$150/SF, dispensaries $150-$300/SF. Mechanical systems, electrical service, and the grow room envelope together represent the majority of hard cost, which is why HVAC design and power capacity are settled first.

Columbus Cannabis Facility Construction FAQ
Common questions about building cannabis facilities in Central Ohio. Visit our full FAQ page for more.
In the Columbus market, indoor cultivation buildouts inside existing buildings typically run $180 to $350/SF, ground-up indoor cultivation $300 to $550/SF, processing and extraction labs $250 to $500/SF, greenhouse and mixed-light facilities $60 to $150/SF, and dispensaries $150 to $300/SF. HVAC and dehumidification, electrical service, and the grow room envelope drive most of the cost. See our indoor cultivation cost guide and use the estimator above.
The Division of Cannabis Control within the Ohio Department of Commerce licenses and regulates cultivators, processors, dispensaries, and testing labs for both the medical and adult-use markets. Facility plans, security systems, and inspections run through the Division, while construction permits, zoning, and fire review stay with the local jurisdiction. TCG designs to both from the first layout.
Ohio licenses cultivators by level. Under the Division of Cannabis Control rules, a Level I cultivator may request to expand its cultivation area up to 100,000 SF and a Level II cultivator up to 15,000 SF once the existing area is in full use. Canopy size drives room count, HVAC tonnage, and electrical service, so TCG plans the building around the license level and a realistic expansion path.
State law requires cannabis operators to be at least 500 feet from a school, church, public library, public playground, or public park, and each municipality controls zoning. Some Central Ohio communities limit or prohibit new cannabis operators, so zoning must be confirmed before you sign a lease or close on land. TCG reviews site eligibility, zoning, utility capacity, and building suitability during feasibility.
Cultivation rooms behave like process spaces, not storage. They need tight, cleanable envelopes (often insulated metal panels), high-capacity HVAC with dehumidification, large electrical services for lighting and cooling, odor control, irrigation and fertigation, security systems that meet state rules, and durable seamless flooring. See our cannabis facility requirements guide.
Often, yes. Industrial and flex buildings with clear height, slab capacity, and a path to more electrical service can be converted faster and cheaper than building new. The main limits are power availability from AEP Ohio, roof and structure for mechanical equipment, and zoning. See adaptive reuse and building conversions.
Yes. TCG self-performs insulated metal panel installation for grow rooms, with more than 1 million SF installed across 38 states, and delivers specialty polyaspartic flooring for cultivation and processing through a 10-year cannabis flooring partnership. Keeping the envelope and floor in-house protects cleanability, schedule, and cost.
A cultivation buildout in an existing building typically takes 6 to 10 months and ground-up facilities 10 to 16 months, plus design, local permitting, and state inspection before operations. Long-lead HVAC, dehumidification, electrical gear, and lighting set the critical path. See our license-to-grow timeline guide.
