When are land possessors NOT required to inspect their property for trespassers?

Land possessors are not required to inspect their property for trespassers when the trespassers are undiscovered. This aligns with the legal understanding of duty of care owed by property owners or possessors. The rationale here is based on the principle that if the land possessor is unaware of someone's presence on their land, there is no reasonable expectation for them to actively inspect or monitor for those individuals. The law holds that land possessors have a duty primarily to protect known entrants, and unless there is a reasonable basis to believe that a trespasser might be present, they can focus on managing their property without the additional burden of inspection.

In situations involving public events, explicit warnings, or adequate security, the land possessor may have a heightened duty to monitor their property. For instance, during public events, due to the influx of guests, possessors must take steps to ensure safety and prevent unauthorized access. Similarly, if there are explicit warnings or established security measures, this can indicate that the possessor is taking responsibility for potential risks, which can lead to expectations for increased vigilance.
