What does “latent defects” mean?

Latent defects are hidden flaws or problems in a product, structure, or system that are not immediately visible or detectable during normal inspection. These defects only become apparent after some time has passed or under specific conditions of use.

Key characteristics:

• Hidden nature: Cannot be discovered through reasonable inspection at the time of purchase or delivery.
• Delayed discovery: Typically emerge weeks, months, or even years after acquisition.
• Inherent flaws: Exist from the point of manufacture or construction, even if not yet visible

Common examples:

• Faulty wiring inside walls that causes electrical problems months later.
• Structural weaknesses in buildings that aren’t visible during walkthrough.
• Manufacturing defects in products that only appear after extended use.
• Software bugs that only trigger under specific, uncommon conditions.

Why it matters:

Latent defects are often covered by warranties or legal protections because they couldn’t reasonably be detected by the buyer before purchase. This is different from “patent defects” (obvious flaws) that should be noticed during normal inspection.
