Houston Cannabis & Hemp Facility Construction

Texas operates a limited medical program (the Compassionate Use Program, CUP) for low-THC cannabis with a small set of state-licensed dispensing organizations. Recreational cannabis is not legal. Hemp and CBD processing are legal under the Texas Hemp Farm Act (2019). In Houston, the construction work that exists right now sits in three categories: CUP cultivation and processing, hemp and CBD processing facilities (Houston has a deep chemical processing and logistics labor pool that maps well to hemp extraction), and shell or warehouse builds positioned for expanded program capacity if Texas law evolves.

Houston cannabis construction runs $122 to $625 per SF depending on use. Indoor cultivation $185 to $470, processing and extraction $240 to $625, dispensary buildout $148 to $345, warehouse conversion to cultivation $122 to $350, and combined cultivation plus processing $210 to $535. Houston multiplier is roughly 0.95 to 1.10x of national average. See national cannabis cultivation cost guide.

TCG actively builds across Greater Houston and brings national cannabis facility experience (a decade and over 1,000,000 SF of IMP installed across 38 states) to Texas operators. Within Texas, that means current hemp and CBD processors, CUP-licensed operators, and any operator preparing facility plans for expanded program capacity. Active commercial cannabis cultivation in Texas remains limited to the CUP program; Houston cannabis projects are framed against national experience applied to Texas regulatory context.

Houston is zone 9a: hot and very humid year-round, heavy rainfall, and Gulf Coast hurricane exposure (June through November). For cultivation, that means dehumidification has to be sized for the latent load with significant safety factor (Houston runs more humid than Dallas or Austin), envelope vapor sealing has to be continuous, and condensate management at HVAC equipment is critical. Self-performed IMP envelopes with continuous vapor-tight seams handle this better than tilt-up with applied insulation.

Houston sits in the Gulf Coast hurricane zone (Harvey 2017, Ike 2008, Beryl 2024 all caused billions in damage). Cultivation facilities here need ASCE 7 wind-rated envelope detailing (windborne debris-resistant openings, IMP face profiles rated for high wind and impact), elevation above the 100-year flood plus freeboard on FEMA Special Flood Hazard Area sites, generator and backup power for extended grid outages after major storms, and roof system selection that survives Category 2 to 4 winds. TCG specifies these systems from preconstruction rather than retrofitting them in.

Sealed envelope (IMP for continuous insulation, integrated vapor barrier, hurricane-rated face profile), heavy electrical service (60 to 90 W per SF total facility for flower-heavy builds), oversized dehumidification sized for Gulf Coast humidity (often 30 to 50 percent more capacity than the same facility in Denver or Phoenix), CO2 enrichment, irrigation and fertigation, security and surveillance, backup power for hurricane-season grid resilience, and process flow that separates mothers, clones, veg, flower, dry, cure, trim, and packaging zones. See IMP for controlled environments.

Flower-heavy cultivation runs 60 to 90 W per SF total facility. A 40,000 SF flower-dominant facility needs roughly 2,000 to 4,000 kW connected load, or 2,500 to 5,000 A at 480V 3-phase. ERCOT grid and CenterPoint Energy (or the local cooperative) interconnection plus transformer lead times of 40 to 80 weeks is the binding schedule constraint. After Hurricane Beryl reinforced Houston grid resilience concerns, backup power sizing also matters more here than in most Texas metros.

Polyaspartic and epoxy floor systems for cultivation rooms and dry areas (chemical resistance, smooth wipeable surface, fast cure), urethane cement at processing wet areas, and properly sealed floor-to-wall transitions. Houston humidity makes moisture testing critical before any coating goes down; we run moisture testing against ASTM F2170 in-situ probes and ASTM F1869 calcium chloride before specifying the system. Specialty flooring is self-performed through our 10-year Cannafloors partnership.

Permitting depends on whether the project is CUP-licensed cultivation/processing, hemp/CBD processing, or warehouse conversion. State licensing (Texas DPS for CUP, Texas Department of Agriculture for hemp) runs in parallel with local permitting through City of Houston Public Works and the Houston Permitting Center, or the suburban authority (Harris County, Fort Bend County, Montgomery County, or municipalities like Sugar Land, Katy, The Woodlands, Pearland, Conroe). Typical local permitting runs 4 to 9 months for ground-up and 2 to 5 for warehouse conversion TI.

Indoor cultivation ground-up: 13 to 19 months from groundbreak (Gulf Coast envelope and dehumidification add to schedule). Warehouse conversion to cultivation: 7 to 13 months. Processing and extraction facility: 11 to 17 months. Dispensary TI: 3 to 6 months. Combined cultivation plus processing: 15 to 23 months. Add 3 to 8 months of preconstruction, design, state licensing coordination, and permitting before groundbreak. Hurricane season (June through November) can pause exterior work; we schedule envelope closure ahead of peak storm exposure when possible.

TCG builds across the City of Houston, Harris County, and the surrounding metro: The Woodlands, Sugar Land, Katy, Pearland, Cypress, Spring, Conroe, League City, Pasadena, Galveston, Tomball, Missouri City, Friendswood, Humble, Baytown, Webster, and the broader Greater Houston region along I-10, I-45, US-59/I-69, Beltway 8, and the Grand Parkway. TCG also builds cannabis facilities in Dallas, Austin, and across all 50 states. See core sector page.
