Retaining Wall · Anne Arundel County, Maryland
Set by local rules
In Maryland, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Anne Arundel 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 Maryland leaves this to local jurisdictions, the reliable answer comes from Anne Arundel County Inspection. Zoning setbacks apply either way.

Walls over a certain height typically require an engineered plan and a building permit.
As one of the more densely populated areas in Maryland, Anne Arundel County (around 598,166 residents) tends to see higher application volumes at its building department, so it helps to prepare your documentation in advance.
