The Model Permission for Encroachment is a license agreement that allows an encroachment to continue until the owner withdraws permission. The model document also features owner protections from claims pertaining to injury or property damage, a requirement that the encroacher comply with the law, and the termination of any rights the encroacher may have to claim adverse possession.

Parks and other public open spaces deliver tremendous benefits to the public and provide a crucial foundation for building, maintaining, and renewing communities. People rely on the permanence of these civic assets in making decisions on where to live and work. Thus, it is no wonder that Pennsylvania law affords great protections to parks from sale or conversion to non-public uses by the municipal governments responsible for their care. This guide describes these protections in brief. [3-page WeConservePA guide]

What should you do if a neighboring landowner encroaches on your organization’s property (e.g., builds a shed or extends their lawn) or otherwise uses the land without permission?
