Remember, it's what you CAN'T SEE, what’s behind the walls, in the attic and in the crawl spaces that can and will eventually impact the Home/environments Air Quality.

Marijuana Grow-Op Remediation

Assure Can Return a Former Grow-Op Property to a Healthy and Legally Compliant Environment - Safely, Effectively, and Quickly

Assure Property Solutions Industrial Hygiene services offer complete assessment and remediation management for successful rehabilitation of marijuana grow-op properties.

What’s Next After an Order to Remedy an Unsafe Building?

Marijuana grow-ops are more common than you think, with many unsuspecting landlords and property managers falling victim to these illegal and potentially dangerous operations.

If a police raid on your property reveals a marijuana grow-op, you will likely receive an Order to Remedy an Unsafe Building that describes the conditions you’ll need to meet before you can resolve your case. The electrical supply to the building will also most likely have been disconnected.

To restore your property to a healthy and legally compliant state, you must provide the municipality with an environmental assessment stating that the building is:

  • fit for occupancy,
  • free from biological and chemical hazards
  • structurally sound

The ESA (Electrical Safety Authority) will also require this information to turn the power back on.

What’s Included in the Environmental Assessment?

A physical assessment of the property to determine:

  • Extent of fungal (usually mould) contamination and its source(s)
  • Any indoor pesticide contamination and its source(s)
  • Extent of water and indoor moisture damage
  • A remediation plan to mitigate the above
  • A verification report that re-evaluates the environmental conditions, post remediation

Who Can Perform the Environmental Assessment?

Unfortunately there are currently no detailed requirements on who can undertake an environmental assessment or the necessary cleanup. This results in wide variation in quality of both the assessment and cleanup.

The ESA however requires that a Certified Industrial Hygienist (American Board of Industrial Hygiene) or a Registered Occupational Hygienist (Canadian Registration Board of Occupational Hygiene), or a Professional Engineer with a M.Sc. in Occupational Hygiene to sign off on the project prior to turning the power back on.

Assure works with Certified Industrial Hygienists, with many years of experience and the most up-to-date training. Our Certified Industrial Hygienists are actively involved in the grow-op remediation process ensuring the quality of the assessment work.

What is a Remediated Grow Op

  • Remediation plan if necessary, including management of mould abatement contracting with our established, qualified contractors
  • Post-remediation assessment and air testing to document that the cleanup work has been completed effectively.
  • Completion of the necessary ESA sign off documentation.

What are the Dangers Presented by a Grow-Op Property?

If not remediated safely and effectively, former marijuana grow-op properties can be highly dangerous to the health and safety of occupants, and even neighbours. Some of the more common risks include:

  • Airborne contaminants from improper changes made to furnace venting or from chemicals.
  • Health effects and allergies caused by moulds and fungi
  • Increased probability of fire from overloaded electrical systems, illegal wiring and extreme heat generated by high intensity lighting
  • Potential for electrocution from illegal electrical bypasses
  • Possible structural damage caused by grower’s improper renovations

Tips for Landlord and Property Managers

  • Screen prospective tenants and check their references thoroughly
  • Record and check identification details
  • Landlords should introduce themselves to the neighbours and let them know that their property is a rental unit
  • Provide neighbours with your telephone number and ask them to report suspicious behaviour to you immediately
  • Advise tenants verbally and in the lease that you check your property regularly, with proper notice
  • Don’t accept cash or post dated cheques for rent payments, personally pick up the rent cheque each month
  • Make it a requirement of the lease that tenants have full insurance
  • Enquire as to which tenant will be registering for hydro and telephone charges
  • Be on location when the tenants move in and reinforce any special conditions of the lease at this time
  • Be a conscientious landlord – Grow House Operators will not risk losing their crop and equipment if they know the landlord checks the property regularly
