A hidden defect is any flaw or defect resulting from inferior design, deterioration, or an unseen construction mistake made prior to sale. By law in Quebec, the seller of a property must disclose to the buyer of a property any hidden defects that may negatively affect the quality or use of the property and any extension of it, including a pool, chimney, deck, shed, or garage.
The most common examples of hidden defects include:
- Cracks in the foundation
- Roof or insulation related defects
- Plumbing or drainage problem
- Inadequate wiring, plumbing, heating or cooling
- Mould in the walls or ceilings (or anywhere for that matter)
- Infestation (vermin, pests, etc.)
- Suicide or violent death having occurred in the home
