Adverse Possession in Pennsylvania
State-specific overview · Property & Real Estate
Pennsylvania requires 21 years of continuous, open occupation to establish adverse possession.
How Pennsylvania treats Adverse Possession
Pennsylvania imposes one of the longest adverse possession periods in the nation at 21 years of uninterrupted occupancy. The possession must be actual, open, notorious, exclusive, and hostile to the true owner's rights. Pennsylvania courts strictly construe adverse possession statutes and require clear proof that the possessor intended to claim the land as their own.
The general definition of Adverse Possession
Gaining legal ownership of land by occupying it openly and continuously for a set period.
If someone uses another person's land openly, without permission, and continuously for many years (typically 7–21 years depending on the state), they may eventually become the legal owner. The original owner must not have stopped them during that time. This doctrine rewards people who improve and maintain land while punishing owners who abandon or ignore their property.
