What are the requirements for a retaining wall?

A retaining wall greater than 3' in height will require a building permit. A retaining wall shall be limited to four feet if it is: (1) within ten feet of any property line; or (2) in the minimum required yard setback for the subject lot, whichever is greater. Elsewhere, a retaining wall shall be no higher than eight feet. Unless there is a minimum horizontal separation of at least four feet between individual retaining walls or fences and retaining walls, a grouping of walls and a grouping of one or more walls and fences shall be seen as a single structure for determining height limits. A retaining wall that will exceed the maximum height requirements will require an Exception Permit
