What type of permission should a homeowner give a neighbor to park an RV temporarily in their backyard?

The appropriate type of permission for a homeowner to grant a neighbor to park an RV temporarily in their backyard is a license. A license is a non-assignable permission that allows one party to enter the property of another for a specific purpose. In this case, allowing a neighbor to park an RV for a limited period is a typical use of a license, as it does not transfer any interest in the property itself and can be revoked by the homeowner at any time.

In contrast, a lease would imply a long-term financial agreement involving rental payments and rights to occupy the property, which would not be suitable for a temporary parking situation. An easement grants a person a right to use another's property for a specific purpose, such as access or utility lines, and is usually more permanent, involving ongoing rights rather than temporary access. Title refers to the legal ownership of property, which is not relevant in this context where permission pertains to temporary access rather than ownership.
