ADU Design in Delaware: what governs your project
Delaware has no statewide ADU statute; ADU rules are set by counties and municipalities. Some jurisdictions, particularly in Sussex County, have established ADU provisions, while others handle them through conditional-use processes.
Energy code
Permitting is local, typically involving zoning compliance, setbacks, and building permits. Septic and well regulations matter in unsewered areas; fees and size limits vary by jurisdiction.
Permitting & plan check
Permitting in Delaware is handled at the county level — New Castle, Kent, and Sussex counties — plus incorporated cities such as Wilmington, Dover, and Newark. Larger or complex projects typically go through county land-use and site-plan review before building permits are issued.
Good to know
- Delaware has no state sales tax, which affects construction material and equipment procurement costs.
- Nearly the entire state lies within the Atlantic Coastal Plain physiographic province.
- The Interstate 95 corridor concentrates the state's heaviest commercial and industrial development.
