Tree trimming on private property is largely unregulated in Allegheny County. Street tree and right-of-way trimming is controlled by municipalities; Pittsburgh requires a permit from the Department of Public Works Forestry Division for any work on street trees.
Pennsylvania common law gives property owners the right to trim branches overhanging their property line to the boundary, without obligation to pay or notify the neighbor, provided the work does not kill the tree. Pittsburgh City Code Chapter 635 requires a free permit from the Forestry Division to prune, plant, or remove any tree in the public right-of-way, and violations carry fines up to $300. Suburban municipalities typically require permits only for street trees. Utility line clearance by Duquesne Light and FirstEnergy is authorized under PUC tariffs and does not require landowner consent within easements.
