A list of the zoning classifications used in Baltimore County with short descriptions are shown below. A Citizen's Guide to Planning and Zoning includes an illustrated description of each of the county's zones. There are general types of zones such as rural, density residential, office, business, industrial and mixed use. Districts may be superimposed onto a zone to provide additional detailed regulation. Currently, there are nine zoning districts.
The Baltimore County Zoning Regulations provides detailed specifications for each of the zones, including the uses that are permitted (e.g., residential, manufacturing, retail), the maximum intensity of the use allowed (e.g., the number of dwellings per acre), and building height limits and building setbacks from roads and other property lines. The regulations may also detail other requirements, such as the number of parking spaces or amount of landscaping required.
