ST. MARY'S COUNTY
St. Mary’s County is a unique blend of deep-rooted American history and forward-thinking innovation, serving as the "Mother County" of Maryland where the state’s first colony was founded in 1634.

Today, it stands as a premier hub for aerospace and defense, anchored by the Patuxent River Naval Air Station, while maintaining a community-focused atmosphere where historic farmsteads and modern developments coexist. Whether you are exploring the tranquility of Leonardtown or the bustling commercial corridors of Lexington Park, St. Mary’s County remains a place where tradition and progress meet.

Southern Maryland Site Work: Frequently Asked Questions
Southern Maryland Site Work: Frequently Asked Questions
In St. Mary’s, Calvert, and Charles Counties, requirements typically depend on the scale of the project:
Retaining Walls: Generally, a building permit is required if a wall exceeds 3 to 4 feet in height or if it supports a "surcharge" (like a driveway or a steep slope) above it.
Driveways: If you are connecting a new driveway to a county-maintained road, you will need an Entrance Permit. In some cases, simple resurfacing of an existing driveway may not require a permit, but new footprints always do.
What is a "Grading Permit" and when is it required?
A grading permit ensures that moving dirt on your property won't cause drainage issues for your neighbors or the local environment.
In most Southern Maryland jurisdictions, you need a grading permit if you disturb more than 5,000 square feet of land or move more than 100 cubic yards of earth.
Pro Tip: If your property is in the Chesapeake Bay Critical Area (within 1,000 feet of the shoreline), regulations are much stricter, and a permit is often required for even minor disturbances.
How long does the permitting process take?
While simple projects in some counties can occasionally be approved "on-demand," most residential excavation or construction permits take between 10 to 30 business days for review. If your property uses a well and septic system, the Health Department must also sign off, which can add time to the process.
Does Adams Property Works handle the permit application?
While the property owner is ultimately responsible for the permit, we regularly work with local planning and zoning offices. We can provide the necessary site drawings, structural details for retaining walls, and professional guidance to ensure your application moves through the system as quickly as possible.
Why is drainage such a big deal in our area?
Because Southern Maryland is surrounded by water, local codes are very strict about hydrostatic pressure and stormwater runoff.
For every project—whether it's a concrete patio or a stem retaining wall—we prioritize proper drainage (like gravel backfills and weep holes) to prevent water from damaging your investment or causing erosion on your land.
