Waltham, MA Fence Regulations: Neighbor Fence Rules (2026)

Massachusetts Fence Law under MGL c.49 addresses boundary fences between adjoining properties and provides procedures for fence viewers to settle disputes, though modern enforcement is rare. More commonly, Waltham neighbor disputes invoke MGL c.49 s.21, the Spite Fence Statute, which treats fences over 6 feet erected maliciously as private nuisances. Neighbors do not share legal obligation to split costs unless mutually agreed. The finished side of the fence traditionally faces the neighbor as a courtesy, though not legally required. Waltham Building Department can mediate boundary questions but real disputes go to Middlesex Superior Court or small claims.
