Anonymised, illustrative composite. The grow-op history itself carried no disclosure duty. The physical defects it left behind were a separate question, and a separate rule.
At a glance
A buyer purchased a renovated bungalow from a company that specialized in buying, remediating, and reselling distressed properties. The listing photos showed a freshly finished basement with new drywall, paint, and flooring. Nothing in the listing or the seller’s disclosures mentioned the property’s history. Six months after closing, the buyer hired an electrician to add a subpanel for a hot tub, and the electrician found extensive amateur rewiring behind the new drywall — undersized wire, missing junction boxes, and signs of chronic moisture that had never been properly addressed, just covered over.
A property search and a conversation with a longtime neighbour confirmed what the listing never mentioned: the home had been a documented former grow operation roughly four years before this sale, remediated and flipped by an earlier owner before the current seller acquired and re-renovated it. Under RECO Bulletin 7.5, “a remediated marijuana grow operation” is named as a stigma example in its own right — a non-physical, intangible attribute with no standalone legal disclosure duty attached to the label itself.
But a grow-op frequently leaves behind exactly the kind of physical conditions this buyer found: altered electrical work, moisture damage from the ventilation and humidity a grow operation requires. Those are governed separately, under Bulletin 7.4’s latent-defect test: a defect is latent, and disclosable, when it “would make a property unfit for habitation, dangerous, or potentially dangerous, and is generally not apparent to someone exercising reasonable care in the inspection of the property.” The stigma label and the physical defects are two different questions with two different rules.
$615,000 purchase price. Two licensed electricians quoted $18,400 and $21,000 respectively to correct the wiring and remediate the mould once the drywall was opened up — figures specific to this file’s own scope of damage, not a market average for grow-op remediation generally.
The case did not turn on whether the seller should have mentioned the grow-op history — under Bulletin 7.5, they were not required to. It turned on whether the seller (the flip company) had actual knowledge of the specific physical conditions — the rewiring, the moisture — behind the new drywall. Fresh drywall over unresolved electrical and moisture problems is also the kind of thing the caveat emptor doctrine’s active-concealment exception is built for: covering evidence of a problem, rather than simply staying silent about it, crosses from non-disclosure into something the doctrine treats as actionable regardless of what was or wasn’t asked.
The buyer’s lawyer requested the flip company’s renovation permits and contractor invoices. The permit history showed drywall and finishing work had been completed without the electrical permit the wiring changes should have required — documentary evidence that supported an inference the company knew, or should have known, exactly what condition the wiring was in when it chose to close the wall over it rather than have it inspected. That paper trail, more than the stigma history itself, was what gave the buyer’s claim its footing.
Had the buyer accepted the wiring and moisture as ordinary wear from an older renovation — the story it was dressed up to tell — the roughly $20,000 repair would have been absorbed entirely out of pocket, with the grow-op history never even entering the picture. The property’s history only became relevant once it explained why the physical work existed in the first place; without that context, the buyer’s only claim would have been a much harder-to-prove “the seller should have known” argument against a stigma with no disclosure duty attached to it at all.
Two things did not line up: the permit file for the property was thin relative to how extensive the visible renovation actually was, and the buyer’s own home-insurance application flagged the address during underwriting, prompting an insurer question about prior claims history that the listing agent had never been asked to explain. A permit history that doesn’t match the visible scope of work is worth checking before waiving a home-inspection condition, not after.
