Pennsylvania · TitlePennsylvania adverse possession: 21 years, or 10 years for a small lot with the possessor's home

Pennsylvania's general rule is that an action for the possession of real property must be commenced within 21 years (42 Pa.C.S. §5530(a)(1)). An entry on the land doesn't toll that period unless a possessory action is commenced within one year after the entry (§5530(b)). Since 2019 a shorter path exists: title may be acquired after no less than 10 years of actual, continuous, exclusive, visible, notorious, distinct and hostile possession (§5527.1(a)), but only for real estate of no more than one-half acre that is improved by a single-family dwelling the possessor has occupied for the full 10 years and is a separate lot of record (§5527.1(h)). The possessor must bring a quiet title action, and the record owners then have one year to respond with an ejectment action (§5527.1(c)–(d)). The 10-year rule doesn't apply to condominium, cooperative or planned community property, or to land owned by the United States, the Commonwealth or a local government unit (§5527.1(f)).
