Clandestine Drug Lab Cleanup Guidelines

Clandestine (clan) drug laboratories are being discovered throughout many areas of the state. Reports show that chemicals used in the production of illicit drugs can contaminate land, a building and its contents, groundwater, or soil where they are dumped. Chemical waste left behind from manufacturing or “cooking” can often present health and safety risks to occupants and/or the general public.

Minnesota Housing requires any Owner/Developer who has actual knowledge of any prior manufacturing of methamphetamines on the premises to disclose that information on the Owner Certification of Environmental Issues form at time of Initial Application. This document can be found in the application materials on our website.

In addition, if a Phase I Environmental Assessment is required, Environmental Assessor shall look for evidence of former methamphetamine manufacturing labs. Refer to requirements regarding Phase I Environmental Assessment located on our website.


To reduce exposure to occupants from harmful chemical waste left behind from clandestine drug labs.


If Owner/Developer discloses knowledge of any prior meth manufacturing on the premises and/or Environmental Assessment reveals evidence of a former drug lab, the following requirements shall apply.
  1. Before Minnesota Housing will commit loan proceeds for specific site improvements, identification of hazardous substances shall be conducted by qualified cleanup company staff to determine cleanup requirements at a specific site based on chemicals found, processes used, and how long the lab was used. This work should be done by experienced hazardous materials (HazMat) contractors. Refer to “Lab Cleanup Guidance” as prepared by the Minnesota Department of Health.
  2. Many counties have developed local public health nuisance or meth lab ordinances. Consult your local county to verify if they have any specific ordinances that may apply to your situation. Such ordinances may require specific cleanup and child protection measures.
  3. It is the responsibility of the Owner/Developer to comply with all applicable regulations and/or ordinances.
