Delaware building departments
This Delaware directory covers 3 Census county equivalents and local building-department guides. Delaware has a relatively centralized code framework, but permits, inspections, zoning, and certificates of occupancy still route through the responsible local jurisdiction.
How permitting works in Delaware
Statewide framework with local administration. A county name is a geographic index, not a promise that the county government issues every building permit. Many projects are handled by a city, town, township, borough, parish, regional office, or independent city.

Delaware Code / county and municipal building officials
Delaware building permits are administered through the applicable county or incorporated municipality. Delaware law defines permits broadly to include building, zoning, certificate-of-occupancy, and related construction approvals, so the local authority for the parcel must be confirmed first.
