Carports in Wilmington are accessory structures regulated under City Code Chapter 48 (Zoning) and require a building permit from the Department of Licenses and Inspections. They must meet the underlying residential district setbacks and lot-coverage limits, and open sides may be required for the structure to be classified as a carport rather than a garage.
Wilmington regulates carports as accessory structures under City Code Chapter 48 (Zoning). In R-1 and other residential districts, Section 48-131 permits a private garage or accessory building 'customarily incident to the uses permitted,' subject to district setback, height, and lot coverage standards in the Chapter 48 bulk and area regulations and the supplementary regulations in Article XI. A building permit is issued by the Wilmington Department of Licenses and Inspections (L&I); inspections are scheduled at 302-576-3030, and permit pickup/inquiries go through luppermits@wilmingtonde.gov or 302-576-3050. Construction must comply with the Delaware State Building Code, which adopts the International Code Council (ICC) family (IBC/IRC), and Delaware State Fire Prevention Regulations administered by the State Fire Marshal. Open sides distinguish a carport from an enclosed garage, which can affect setback and lot coverage calculations - confirm classification with L&I before submitting plans. Carports in front yards are generally restricted; placement is typically limited to side or rear yards behind the principal dwelling. New Castle County does not issue building permits inside the City of Wilmington; the city is its own permitting jurisdiction. Confirm exact district setbacks, maximum height, and any lot-coverage cap with L&I (302-576-3050) before construction.
Building a carport without a permit, encroaching into a required yard, exceeding height or lot coverage, or misclassifying the structure can trigger stop-work orders, retroactive permitting, removal orders, and fines under Chapter 48 and the building code, enforced by the Department of Licenses and Inspections.
