What is a Latent Defect?
A latent defect is a hidden flaw in a property that is not visible during a typical inspection and may affect its safety, use, or value.
Why Do Latent Defects Matter in Real Estate?
In Canadian real estate, sellers are legally obligated to disclose known latent defects that make the home unsafe or unfit for habitation. These cannot be easily detected by the buyer or inspector.
Examples of latent defects include:
- Mold behind walls
- Foundation cracks or structural instability
- Undisclosed water damage or past flooding
If the seller fails to disclose a known latent defect, they may face legal consequences. Buyers should include inspection conditions and seek professional advice for potential red flags.
Understanding latent defects protects buyers from surprise repairs and helps sellers meet legal disclosure obligations.
Example of a Latent Defect
After moving in, the buyer discovered black mold behind the drywall. The seller had not disclosed it, resulting in a legal claim for latent defect.
