Delaware's Building Permit Landscape

Last reviewed: April 2026

Delaware is unique in that it has no statewide building code enforcement. Permitting authority rests entirely at the county level — New Castle, Kent, and Sussex counties each manage permits for unincorporated areas — while cities like Wilmington, Dover, Newark, and Middletown operate their own independent building departments.

Across virtually every jurisdiction in Delaware, a site plan showing property lines, setbacks, and easements is a standard required document for most permit applications. Before submitting, confirm whether your project falls under county authority or your municipality's building department — in towns like Georgetown, you may need both a town-level and a separate Sussex County building permit.

In Wilmington, the Department of Land Use and Planning handles zoning, site plan review, and building permit issuance. In Middletown, deck permit applicants must submit a Site Plot Plan showing all lot dimensions and setback distances — and that plan may be drawn by the homeowner without a professional seal.

Common Delaware Projects That Require a Site Plan

If you're planning any of the following projects in Delaware, a site plan is almost certainly part of your permit application:

  • Fence permits — required in Wilmington and most Delaware jurisdictions; rear/side fences up to 6 ft and front yard fences of 3–4 ft are standard, with permit requirements varying by city
  • Room additions and home additions — a site plan showing the proposed footprint relative to property lines is required across New Castle, Kent, and Sussex counties
  • Deck permits — Middletown requires a Site Plot Plan with all lot dimensions and setback distances for every deck application
  • Detached garage and accessory structure permits — required across most Delaware counties and municipalities
  • Shed permits — Kent County requires a permit for any shed 101 sq ft or greater
  • Gazebo and pergola permits — treated as accessory structures in most Delaware jurisdictions
  • Pool permits and lot coverage verification — site plans showing all structures, pavers, and lot coverage are standard requirements
  • Retaining wall permits — Kent County requires permits for walls over 4 feet in height
  • Driveway permits — required in many Delaware municipalities when a driveway affects lot coverage or drainage
  • Demolition permits — Rehoboth Beach requires proof of DNREC Air Quality Management form submission when hazardous materials may be present
  • Short-term rental licensing — some Delaware municipalities require a site plan as part of short-term rental permit applications
  • Sign permits — commercial properties in Wilmington and other cities require a site plan showing sign placement relative to property lines
  • HOA submissions — particularly in fast-growing Middletown communities where HOA restrictions frequently exceed municipal code requirements
  • Sediment and erosion control plan approvals — required in Sussex and Kent counties for projects disturbing significant land area
  • Coastal zone and DNREC environmental review submissions — required for any project near beaches, wetlands, or the Delaware Bay

Delaware's Unique Permitting Environment

Sussex County has a particularly important requirement: any project disturbing 5,000 square feet or more requires a Sediment and Erosion Control Plan — called a Residential Standard Plan — which must be obtained before a building permit is issued and before any site disturbance begins. Many Kent County projects carry a similar separate erosion and sediment control permit requirement. The Delaware Department of Natural Resources and Environmental Control (DNREC) has regulatory authority over all projects near beaches, wetlands, and the Delaware Bay — and Delaware's Coastal Zone Act applies to construction near tidal waters.

In Rehoboth Beach, any structure that affects lot coverage — including sheds, fences, driveways, patios, and walkways — requires a current property survey, and ocean-block projects require a DNREC Shoreline Construction Approval Letter. Wilmington's historic districts add yet another layer: projects that would be permit-exempt elsewhere (such as replacing doors, gutters, or exterior paint) may require permits in designated historic areas. Understanding which rules apply to your specific address is the critical first step before ordering any site plan. If you're navigating impervious surface requirements, our A Guide to Impervious Surface Calculation can help clarify what your jurisdiction may require.

How MySitePlan Works for Delaware Property Owners

Ordering is simple: submit your property address and project details online, and your Drafterra Certified drafter will produce your professionally drafted plan within 24 hours. Choose the plan level that fits your project:

  • Basic Site Plan — $99: Property lines, primary structure roofline, lot dimensions, north arrow, and scale. Great for project planning.
  • Medium Site Plan — $119 (most popular): Adds measurements between features, trees, driveway, accessory structures, and swimming pool. Ideal for most Delaware building permit and HOA applications.
  • Detailed Site Plan — $159: Adds paths, shrubs, lawn, landscaping, and septic/utilities. Highest level of detail for residential projects.
  • Commercial Site Plan — $179: Includes parking, ingress/egress, dumpster areas, and parking spaces.
  • Commercial "The Works" — $279: Adds legal setbacks, custom size, DWG file, topography, impervious surface calculation, and vicinity map.

Larger cities including Wilmington, Newark, and Middletown operate independent building departments — verify jurisdiction before applying.
Sussex County Sussex County Building Permits Office Projects disturbing 5,000+ sq ft require a Residential Standard Plan (Sediment & Erosion Control Plan) before a building permit is issued and before any site disturbance begins.

Kent County Kent County Department of Planning Services Plot plans are explicitly required for several permit types in unincorporated Kent County, including sheds 101 sq ft or greater, retaining walls over 4 feet, and fences over 4 feet. Separate erosion and sediment control permits are commonly required alongside building permits for qualifying projects.
City of Wilmington City of Wilmington Department of License & Inspections Wilmington operates a full building department independent of New Castle County, handling zoning administration, site plan review, subdivision review, and building permit issuance. Fence permits are required and regulations cover height, placement, and materials. Historic district projects may require permits for items typically exempt elsewhere, including exterior alterations.

Site plans are required for new construction, additions, and accessory structure permits. Applicants should confirm jurisdiction based on their specific parcel location.
