Latent defects are hidden or concealed defects in a house that are not readily apparent upon inspection. They may not be discovered until after the house has been purchased, and can include issues such as:

1. Structural problems: Latent defects can include issues with the foundation, framing, or other structural elements of the house.
2. Plumbing or electrical problems: Latent defects can include issues with the plumbing or electrical systems that are not visible or apparent upon inspection.
3. Environmental hazards: Latent defects can include issues such as mold, asbestos, or lead paint that are not visible or apparent upon inspection.

Latent defects can be difficult to detect, as they are not readily apparent upon inspection. It is important to carefully inspect a house before purchasing it, and to consider hiring a professional home inspector to identify any potential latent defects. If latent defects are discovered after the purchase of a house, it may be necessary to seek legal remedies to address the issue.
