Zoning Districts
Dover's zoning code divides the city into residential, commercial, and industrial districts. The full list of districts and their development standards — including minimum lot sizes, setbacks, height limits, and permitted uses — is found in Title 5 of the Dover Code of Ordinances on Municode.
Key residential districts include R-8 and R-10 (single-family), and RM-1 and RM-2 (multi-family). Commercial districts range from C-1A (neighborhood commercial) to C-4 (highway commercial). Industrial and mixed-use areas fall under IO (Industrial-Office) and M (Manufacturing) classifications.
Note on setbacks: Specific setback dimensions for each district are provided in the Dover Code of Ordinances. The Planning & Inspections Department at (302) 736-7196 can confirm the setback requirements for your property and proposed project.
ADU Rules
Delaware does not have a statewide accessory dwelling unit (ADU) law. Whether ADUs are permitted in Dover depends on the city's local zoning ordinance. Contact the Planning & Inspections Department at (302) 736-7196 or review the zoning code on Municode for ADU provisions in your specific district.
