How is Baltimore zoned?
Baltimore regulates land through 66 zoning districts, and its residential naming is unusually honest about the city's built form. Four districts are labelled Row House And Multifamily Residential, coded R-5 through R-8, together covering roughly 15,839 acres. That is more than every detached residential district combined, and it states plainly that the rowhouse is Baltimore's defining housing type.
The detached districts run R-1 through R-4 with lettered variants, together covering roughly 9,730 acres.
Maritime Industrial is the third largest classification at roughly 5,482 acres, ahead of every industrial district. In a port city that ranking is the essential context, and an Industrial Mixed Use district at about 495 acres provides a transitional category between the working waterfront and other uses.
The campus districts are the other distinguishing feature. Two Educational Campus districts cover roughly 1,189 acres between them and a Hospital Campus district about 605. Zoning universities and hospitals as their own campus classifications rather than as institutional exceptions makes those large landholdings explicit.
Open Space is the largest classification at roughly 6,996 acres. The downtown is divided into subdistricts, with the core subdistrict covering roughly 711 acres. An Office Industrial Campus district covers about 438 acres. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
