Retaining Wall Permits

Published by data.montgomerycountymd.gov | Montgomery County of Maryland | Metadata Last Checked: October 20, 2025 | Last Modified: 2025-10-18
A permit is required to install a retaining wall if the height of the wall measured from the bottom of the footing to the top of the wall is over 48 inches unless supporting a surcharge. A permit application for a retaining wall installed on the private property line must be accompanied by a letter of approval from the adjacent property owner. Occasionally, lot conditions require approvals from other agencies such as easement holders, or homeowner associations. Any dispute as to whether a Retaining Wall has extended into a neighbor’s property or questions about the location of property lines is a legal matter to be resolved by the property owners. Any Retaining Wall installed within the County right of way will not be permitted and will be required to be removed Update Frequency : Daily
