Buying Land in Prince George's County, Maryland
Seat Upper Marlboro. Prince George's is generally the more urbanized of Maryland's two big DC suburbs, but that description fits its inner, built-out north far better than its more rural south, where working farms and large-lot Rural Estate zoning still hold real acreage along the Patuxent and Potomac corridors. Zoning here runs through the same bi-county planning agency, M-NCPPC, that Montgomery County also relies on.
One county, two very different land-use realities
Prince George's County borders Washington, DC directly, and its inner communities -- along the Beltway, the Metro Green and Blue lines, and the National Harbor waterfront -- are as densely built and urbanized as anywhere in the Maryland suburbs, generally more so than comparable areas of neighboring Montgomery County. That description, however, applies far more to the county's northern and central sections than to its south, where Prince George's still holds a meaningful base of working agricultural land, particularly toward the Patuxent River corridor and the county's border with Charles and Calvert counties.
The county's Rural and Agricultural zoning categories -- including the R-A (Residential-Agricultural) zone, which allows large-lot residential development on 2-acre minimum lots while encouraging continued agricultural use as the primary activity -- still cover real acreage in the county's south. A land buyer should treat Prince George's less as a single, uniformly urban jurisdiction and more as two distinct land-use environments sharing one county government: confirm a specific parcel's actual zoning category and its practical surroundings, rather than assuming either the dense-suburb or rural-farm stereotype applies by default.
Zoning runs through a bi-county agency, and the ordinance was recently rewritten
Like Montgomery County, Prince George's shares its planning and zoning administration with a bi-county agency rather than running a standalone county planning department: the Maryland-National Capital Park and Planning Commission (M-NCPPC) handles zoning district administration, subdivision review, and the county's General Plan for both jurisdictions, under separate Prince George's and Montgomery zoning ordinances. Starting in 2014, the County Council led a multi-year Zoning Ordinance Rewrite (ZOR) effort, working with M-NCPPC, outside consultants, and more than 400 public meetings, that replaced the county's roughly 50-year-old zoning code with a substantially updated ordinance and subdivision regulations.
For a buyer, this history matters in a specific, practical way: older property records, real estate listings, or even older county documents may still reference pre-rewrite zone names and standards that no longer match the current ordinance. Always confirm a parcel's current zone designation directly with M-NCPPC's Prince George's County Planning Department rather than relying on an older document or a listing's stated zoning category. That rewrite also created an entirely new family of transit-oriented zones concentrated around the county's 15 Metrorail stations -- see our dedicated standalone on Prince George's County zoning near Metro for what those zones mean for a nearby parcel.
Critical Area exposure and the regional tobacco-to-farmland transition
Prince George's County Council established the county's Chesapeake Bay Critical Area Overlay Zones by ordinance in 1988, and the resulting Critical Area extends along the Patuxent, Potomac, and Anacostia Rivers -- a broader set of waterways than a single-river county typically has to account for. A parcel doesn't need to sit directly on the Potomac near the District line to fall inside the boundary; the Patuxent corridor in the county's rural south and stretches of the Anacostia further north both carry the same 1,000-foot Critical Area exposure, layered on top of whatever base zoning (urban, suburban, or Rural-Agricultural) otherwise applies.
Prince George's is also one of five counties -- along with Anne Arundel, Calvert, Charles, and St. Mary's -- served by the Southern Maryland Agricultural Development Commission (SMADC), created in 2000 specifically to help the region's farmers transition away from tobacco following Maryland's tobacco buyout program. If you're evaluating farmland in the county's south with an eye toward its agricultural history, ask SMADC or the county's own agricultural planning staff whether a specific parcel was enrolled in the tobacco transition program, since that history can carry its own land-use conditions distinct from ordinary zoning or Critical Area status.
