Retaining wall permit thresholds are municipal. Most Westchester towns require building permits for walls over 4 ft, with engineered plans for walls over 4–6 ft.
Westchester County has no county-level retaining wall ordinance; regulation is municipal. Typical thresholds: walls under 4 ft (measured from bottom of footing to top of wall) may be exempt; walls over 4 ft generally require a building permit with engineered plans; tiered walls are measured cumulatively in most towns. Walls within wetland buffers may require Westchester County Soil and Water Conservation District review or DEC wetlands permits.
