Marijuana Grow Operation Assessments


Residential dwellings used as marijuana grow operations (grow-ops) may have significant structural, electrical and heating system modifications not in accordance with applicable building, natural gas and electrical codes, such as overloaded existing electrical system or a bypass circuit to avoid paying for the electricity required to power the high intensity light bulbs and fans, disconnected furnace venting, or holes in floors and walls for increased airflow. These alterations help to replicate warm, humid climates where plants flourish and produce high potency marijuana. Such modifications may result in considerable structural damage and may lead to moisture and toxic mould.  The building may be further contaminated by pesticides and other chemicals used to facilitate the growing process.  Our consultants perform detailed mould and structural assessments of former marijuana grow operations to generate effective remediation strategies and provide post-remediation inspection and testing services to ensure that the building is fit for occupancy.
