Drone Laws in Maryland: Flying Near Washington DC, BWI, and the Chesapeake Bay

Maryland is split into two distinct airspace environments. The western and central portions of the state fall under the Washington DC Special Flight Rules Area and Flight Restricted Zone -- the same restrictions that affect northern Virginia. The eastern and coastal portions, including the Eastern Shore and the Chesapeake Bay, are less complex but have their own considerations for waterway operations and state park access.

Federal Rules Apply Throughout Maryland

FAA regulations govern all drone operations in Maryland:

• Part 107 certificate required for commercial operations
• LAANC authorization required in Class B, C, D, and applicable Class E airspace
• 400 ft AGL altitude limit in uncontrolled airspace
• Anti-collision lighting required for night operations
• Remote ID required for all drones 250g and above

Check airspace classification and LAANC availability for any Maryland location at uas-skycheck.app before flying. Much of the DC corridor and Baltimore area is controlled airspace.

The DC Flight Restricted Zone and SFRA in Maryland

The Washington DC airspace restrictions extend directly into Maryland:

Flight Restricted Zone (FRZ): The 15 NM radius centered on Reagan National Airport (DCA) extends into Prince George's County, parts of Montgomery County, and reaches as far north as areas near the University of Maryland's College Park campus. No drone operations within the FRZ without a specific FAA security waiver. LAANC does not apply inside the FRZ.

Special Flight Rules Area (SFRA): The 30 NM radius from DCA extends further into Maryland, covering most of Montgomery County, significant portions of Prince George's County, and portions of Howard County. Operations in the SFRA require LAANC authorization (where available) or an SFRA Security permit.

The practical consequence: pilots in the Maryland suburbs of DC -- Bethesda, Rockville, Silver Spring, College Park, Greenbelt, Bowie -- are commonly inside the FRZ or SFRA. Checking your exact coordinates against the FRZ boundary is essential before assuming any authorization is obtainable.

College Park Airport (CGS): College Park Airport, which claims to be the world's oldest operating airport, sits within the DC SFRA. Its Class D airspace adds another layer of authorization requirements for pilots operating in Prince George's County.

Baltimore/Washington International Airport (BWI)

BWI has Class B airspace extending from the surface outward with floors rising at increasing distances. The BWI Class B significantly affects Anne Arundel County, portions of Howard County, and reaches into Baltimore County.

For drone pilots:

• Portions of Annapolis, Glen Burnie, Linthicum, and Elkridge fall within BWI Class B
• LAANC is available at BWI, but UAS Facility Map ceilings are often low near the airport
• The Baltimore Inner Harbor and Downtown Baltimore fall under BWI Class B influence

Baltimore/Washington Thurgood Marshall Airport -- Additional Coverage

The three-airport system serving the DC/Baltimore corridor creates overlapping controlled airspace:

• DCA (Reagan National): Controls the FRZ/SFRA to the southwest
• IAD (Dulles): Class B extends into Montgomery County from the west
• BWI: Class B covers the Baltimore corridor from the north

A pilot in Montgomery County or Howard County may need to navigate overlapping BWI and IAD Class B boundaries simultaneously. Check your specific coordinates carefully.

Maryland State Drone Law

Maryland passed drone-specific legislation that addresses several operational areas:

Privacy: Maryland Code, Criminal Law Article § 3-902 prohibits intercepting oral communications using a drone. State courts have applied privacy protections to drone photography in contexts where individuals have a reasonable expectation of privacy. Commercial operators should be aware that capturing audio without consent in Maryland is a criminal offense.

Law enforcement: Maryland law restricts law enforcement drone surveillance without a warrant. These provisions affect government operations, not civilian commercial use.

Maryland does not have a comprehensive state drone preemption law. Local governments in Maryland can and do enact drone ordinances. Unlike states with explicit preemption provisions, Maryland municipalities have more latitude to regulate drone operations.

Maryland State Parks and Public Lands

Maryland Park Service manages 77 state parks. Drone operations in Maryland state parks are generally prohibited without a Special Use Permit from the Department of Natural Resources (DNR). The permit process requires advance application, and approval is not guaranteed for all locations or purposes.

Commercial filming in state parks requires a Maryland Film Production Permit in addition to DNR authorization. Contact the Maryland Film Office for commercial productions.

Assateague Island National Seashore: Jointly managed by the National Park Service and Maryland DNR, Assateague has strict restrictions on drone operations due to sensitive shorebird nesting habitat. NPS no-drone policies apply within the national seashore portions; coordinate with Maryland DNR for state park portions.

The Chesapeake Bay and Waterway Operations

The Chesapeake Bay creates unique operational considerations:

• Open water operations over the Bay are generally unregulated by state land-use rules (you are not on state land)
• Airspace over the Bay is Class G at low altitudes away from airports
• The Bay Bridge corridor and Naval Station Annapolis area have controlled airspace considerations
• Some Bay tributaries and waterways near Aberdeen Proving Ground have military restricted airspace
• Maryland environmental regulations apply to filming operations that involve launching from or landing on sensitive tidal wetlands

The Chesapeake Bay is popular for aerial photography -- it combines protected Class G airspace with visually compelling scenery. Pilots should verify airspace for their specific launch point, as Bay access often requires crossing state park or private property to reach the water's edge.

Aberdeen Proving Ground

Aberdeen Proving Ground in Harford County is an active Army installation with associated restricted airspace. R-4001A/B/C extends over portions of Harford County and the upper Chesapeake Bay. Operations near Aberdeen require verifying restricted area status and timing before launch.

Naval Air Station Patuxent River (NAS PAX)

NAS Patuxent River in St. Mary's County is the Navy's primary aircraft test and evaluation center. Its Class D airspace and associated restricted areas cover significant portions of southern Maryland. Military test aircraft routinely operate at unusual altitudes and airspeeds in the surrounding airspace. Pilots in Calvert, St. Mary's, and Charles counties should check for NAS PAX Class D and any active restricted areas before operating.

Eastern Shore

The Eastern Shore counties (Kent, Queen Anne's, Talbot, Caroline, Dorchester, Wicomico, Somerset, Worcester) are largely Class G airspace away from their regional airports. Drone mapping, agricultural surveying, and inspection work is common here.

Regional airports with Class D airspace on the Eastern Shore:

• Easton (ESN)
• Salisbury-Ocean City (SBY) -- Class C

Ocean City, Maryland's most-visited coastal destination, falls under SBY Class C influence. Operations near the Ocean City boardwalk and beachfront require LAANC authorization at Salisbury.

Practical Summary for Maryland Drone Pilots

Maryland's airspace complexity is highest in the DC and Baltimore corridors. Pilots who assume Class G in the Maryland suburbs of DC are making a potentially serious legal error.
