Philadelphia County follows Pennsylvania common law for shared fences; no statewide cost-sharing statute. Each owner responsible for their own fence; party walls covered separately under Philadelphia Code §9-200.
Pennsylvania has no Good Neighbor fence law. Owners not required to share fence costs unless by written agreement. Spite fence doctrine recognized in PA common law: maliciously erected fences with no legitimate purpose may be enjoined. Party walls (common in Philadelphia rowhouses) regulated separately. Surveys recommended before installation to avoid encroachment disputes.
Civil disputes only; no code enforcement for cost-sharing. Encroachments can force removal via quiet title action.
