Zoning Districts
Newark's zoning code (Chapter 32) divides the city into residential, business, industrial, and special-purpose districts. Key residential districts include RE (Residential Estate), RS (Residential Suburban), RD (Residential District), RH (Residential High), and RT (Residential Townhouse). Commercial districts range from BB (Business Block) and BN (Business Neighborhood) to BC (Business Community) and BL/BLR (Business Limited). Industrial land is designated MI (Manufacturing/Industrial), with a MOR (Mixed Office/Research) district for office and research uses.
Two districts reflect Newark's university character: the UN (University) district covers the University of Delaware campus, and the STC (Student Transition Corridor) manages the interface between campus and established neighborhoods. The PL (Parkland) and SFHA (Special Flood Hazard Area) designations apply to parks and flood-prone areas respectively.
Note on setbacks: Dimensional standards — including minimum lot sizes, setbacks, and height limits — for each district are set out in § 32-56 of the Newark Code of Ordinances. For the RS district, the rear yard minimum is 30 ft (§ 32-56.2(e)). Contact Planning & Development at (302) 366-7000 to confirm setback requirements for your property and district.
ADU Rules
No formal citywide by-right accessory dwelling unit (ADU) ordinance has been confirmed for Newark. Delaware has no enacted statewide ADU preemption — SB 23 of the 152nd General Assembly was introduced in 2023 but was substituted and did not become law before the session ended. Contact the Newark Planning & Development Department at (302) 366-7000 for the most current local ADU rules in your specific zoning district before planning any ADU project.
Development Process
Development in Newark generally requires:
- Zoning Verification — Confirm your proposed use is permitted in the applicable zoning district using the interactive zoning map or by contacting Planning & Development at (302) 366-7000
- Site Plan Review — Required for commercial, multi-family, and larger development projects
- Building Permit — Submit construction documents to the Planning & Development Department

Variances, special use permits, and rezonings are reviewed by the Newark Planning Commission and Board of Adjustment.
Key Considerations

- The University of Delaware's presence creates unique zoning dynamics, particularly in the STC district near campus
- HOA covenants and deed restrictions may impose requirements beyond city zoning
- Delaware has no enacted statewide ADU preemption (SB 23 was not passed) — ADU rules are set by local ordinance
