Retaining Wall · Wayne County, Michigan
In Michigan, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Wayne County.
Most jurisdictions exempt a retaining wall up to 4 feet tall (measured from the bottom of the footing) with no surcharge, following the IRC baseline; over 4 feet, or any wall holding back a slope, driveway, or structure (a surcharge), needs a building permit and engineered drawings. Many cities lower the threshold to 3 feet, concrete or masonry walls often need a permit at a lower height, and tiered walls count as one combined wall. Because Michigan leaves this to local jurisdictions, the reliable answer comes from City of Wayne Building & Engineering. Zoning setbacks apply either way.

As one of the more densely populated areas in Michigan, Wayne County (around 1,772,259 residents) tends to see higher application volumes at its building department, so it helps to prepare your documentation in advance.
Because of severe winter weather in Michigan, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Michigan Building Code.
In highly urbanized counties like Wayne County, many properties are also subject to Homeowners Association (HOA) approval before a city permit can be applied for. If you live in a designated historic district, the local architectural committee may also have review authority over your Retaining Wall.
