Your Seattle Construction Cost Estimate
Seattle and Washington Cannabis Facility General Contractor
Washington has a mature recreational cannabis market, and the facilities that supply it are demanding builds. Cultivation is an environmental-control problem: temperature, humidity, airflow, and sanitation have to be held precisely, or yields and quality suffer. Extraction adds C1D1 occupancy and code requirements that most general contractors have never touched.
TCG is a cannabis construction specialist. We deliver design-build cultivation and processing facilities with in-house MEP engineering for grow-room dehumidification and airflow, self-performed IMP envelope for clean, washable grow rooms, and specialty resinous flooring through our long-standing flooring partnership. See our national cannabis practice.
How Much Does a Cannabis Facility Cost in Seattle?
Seattle cannabis facility costs are driven by HVAC and dehumidification, electrical capacity, and the build-out of clean, sealed grow environments, on top of the region's prevailing wage and seismic costs. Extraction space carries a premium for C1D1 requirements.
| Project Type | Seattle Cost Range |
|---|---|
| Cultivation TI / warehouse conversion | $120-$280/SF |
| Ground-up indoor cultivation | $200-$400/SF |
| Extraction / processing (C1D1) | $350-$650/SF |
| Grow-room IMP envelope | $14-$26/SF |
| Resinous cultivation flooring | $7-$16/SF |
HVAC and dehumidification plus electrical capacity are the dominant cost drivers in cultivation. Use our AI estimator above or schedule a call.
Why TCG for Washington Cannabis
Cannabis cultivation lives or dies on environmental control, and TCG keeps the relevant engineering and trades in-house. Our MEP team designs the dehumidification and airflow that protect yields, we self-perform the IMP envelope that gives clean, washable, sealed grow rooms, and we install the resinous flooring that cultivation and extraction require, through a partnership built specifically around cannabis grow facilities.
Under one design-build contract, the mechanical system, envelope, and flooring are designed together, and our structural engineers handle Seismic Design Category D. For operators racing a license clock, that integration is the difference between hitting a deadline and missing it.
