Former grow-ops and stigmatized properties: what to check
Doorvia Guides · June 1, 2026
Remediation quality, mould, electrical bypasses and insurability matter more than the label itself.
Homes previously used for illegal cannabis production can carry real physical problems: moisture and mould in walls and attics, altered or bypassed electrical, removed vapour barriers, and modified plumbing. Some have been fully remediated to a documented standard; many have not.
Insurance and financing are the practical hurdles. Several lenders and insurers restrict these properties, and you may need documentation of remediation from qualified professionals.
If you are considering one, insist on the remediation records, an air quality and mould assessment, an electrical safety authority inspection, and written confirmation from both a lender and an insurer before you go firm. Price accordingly - resale will face the same questions.
