Retaining walls over 4 feet in Westland require a building permit with engineering drawings. Walls under 4 feet may still need permits depending on location and grade. Michigan Residential Code governs.
Westland regulates retaining walls under the Michigan Residential Code and city zoning. Walls exceeding 4 feet in height measured from bottom of footing to top of wall require a permit with engineered drawings stamped by a Michigan licensed professional engineer. Walls under 4 feet may still require permits if they support a surcharge (driveway, structure, slope) or are located in easements or near property lines. Drainage, frost depth, and soil conditions in Wayne County clay soils must be addressed in design. Masonry, timber, and segmental block walls each have specific code requirements. Unpermitted failed walls that damage neighbor property create civil liability. Consult Westland Building Department for specific project requirements.
