What is a Material Latent Defect in BC real estate?

Direct answer

A Material Latent Defect is a defect that cannot be discovered by a reasonable inspection AND that meets one of four BCFSA-defined materiality tests: (1) it makes the property dangerous or potentially dangerous to occupants; (2) it makes the property unfit for habitation; (3) it makes the property unfit for the buyer's known intended use; or (4) it would involve a significant cost to remedy. Examples include: a previous fire or grow-op that has been remediated but altered structural elements, a leak inside a wall hidden by drywall, a buried oil tank, or a foundation crack covered by paint. Rule 59 of the Real Estate Services Rules imposes a POSITIVE DUTY on the seller's licensee (NOT the seller themselves) to DISCLOSE in writing every material latent defect they know or reasonably ought to know about. The duty runs to ANY party — including unrepresented buyers and other realtors — and survives even where the seller refuses to consent to the disclosure. A licensee who fails to disclose a known material latent defect faces BCFSA discipline AND personal civil liability; the buyer may rescind the contract or sue for damages depending on when the defect is discovered.
