Zoning Districts

Seaford's zoning code (Chapter 15) establishes four residential districts and four commercial/industrial districts. Residential districts range from R-1 (Low Density Residential) through R-2 (Medium Density), R-3 (High Density), and R-4 (Institutional Residential). Commercial areas are designated C-1 (General Commercial), C-2 (Highway Commercial), and C-3 (Riverfront Enterprise Zone) — the latter a special economic development district along the Nanticoke River waterfront. Light industrial uses are permitted in the M-1 district.

Note on setbacks: Specific setback dimensions for each district are defined in Chapter 15. Contact the Seaford Code Department at (302) 629-9173 for setback requirements applicable to your property and proposed project.

ADU Rules

No confirmed dedicated accessory dwelling unit (ADU) ordinance has been found for Seaford. Delaware SB 23 (effective April 1, 2024) limits the ability of local governments to prohibit ADUs outright, which may affect Seaford's regulations. Contact the Seaford Code Department at (302) 629-9173 for current ADU guidance before planning any project.

1. Zoning Verification — Confirm your proposed use is permitted in the applicable zoning district using the zoning map or by contacting the Code Department at (302) 629-9173
2. Site Plan Review — Required for commercial, multi-family, and larger development projects
3. Building Permit — Submit construction documents to the Seaford Code Department
