Why do you need liability insurance on land you do not use?

Liability insurance

In the Unites States, a landowner can sometimes be held liable for certain occurrences on the owned land.

A Landowner is typically NOT held liable for the actions of tenants. This is what Renters Insurance is for. A Tenant can purchase property and liability insurance on a tenants policy. A property owner also is Typically NOT liable for the actions of criminals or others that may have entered your property illegally.

So while its a good idea to maintain some type of Liability Insurance for Vacant Land to cover some occurrences where the owner might be liable. One should not presume that the property owner is liable for anything and everything that might occur on the property.
