How zoning works in Seaford

Seaford's development pattern reflects its history as a manufacturing hub (long home to a major DuPont nylon plant) alongside its role as a commercial center for western Sussex County, with growth concentrated along the town's highway corridors and its Nanticoke River waterfront rather than a single redevelopment district. Delaware has no statewide ADU mandate or missing-middle preemption, so any accessory or multifamily allowance in Seaford comes entirely from the town's own code.
