Latent vs. Patent Defects
The distinction between a construction or property defect that is hidden and not reasonably discoverable upon ordinary inspection (latent) versus one that is visible and obvious (patent), which drives when discovery and limitations periods begin.
A patent defect is one a reasonable inspection would reveal at the time of purchase or completion, such as visible cracking, an obviously uneven floor, or missing fixtures. A latent defect is hidden within the structure and not reasonably discoverable through ordinary inspection, such as a concealed waterproofing failure, defective structural framing behind finished walls, or a foundation problem that only manifests years later. The classification matters enormously because many jurisdictions apply the discovery rule to toll the statute of limitations for latent defects until the defect is or reasonably should have been discovered, while a patent defect's limitations period typically runs from the time it was or should have been observed.
In real estate transactions, the distinction also affects seller disclosure obligations and 'as-is' clause enforceability; sellers are more often required to disclose known latent defects than patent ones a buyer's own inspection should catch, and caveat emptor defenses are stronger for defects a buyer could have discovered. In construction litigation, latent defects also interact with statutes of repose, which impose an absolute outer deadline regardless of discovery, meaning a defect can be both undiscoverable and time-barred at once.
Juricratic separately dials the 'discoverability' and 'time elapsed since substantial completion or sale' variables for a defect claim, since the two interact nonlinearly: a highly latent defect discovered late in a jurisdiction with a short repose period can be barred entirely regardless of how strong the merits are, a structural fact the simulation surfaces rather than smooths over.
How it actually shows up
Counsel classify a claimed defect as latent or patent early in a case because the classification often determines whether the claim survives a statute of limitations or repose defense, and plaintiffs typically develop expert testimony establishing when a reasonable inspection would or would not have revealed the problem.
- Does an 'as-is' clause waive claims for latent defects?
- It depends on the jurisdiction and the clause's wording; many courts hold that as-is clauses do not waive claims for actively concealed or fraudulently undisclosed latent defects even though they bar claims for defects a reasonable inspection would find.
- What is a statute of repose and how does it differ from a statute of limitations?
- A statute of limitations runs from when a claim accrues or is discovered; a statute of repose runs from a fixed event, often substantial completion, and bars claims after that period regardless of when the defect was discovered.
- Who has the burden of proving a defect was latent rather than patent?
- This varies by jurisdiction and claim type, but the party seeking the benefit of a discovery-rule tolling argument (usually the plaintiff) typically bears the burden of showing the defect was not reasonably discoverable earlier.
