Building Permits
Sussex County homeowners should check the Building Permit Office, Building Code Office, sediment and stormwater requirements, and county inspection process before construction, additions, remodeling, or alterations.
Permit and scope questions
Sussex County says all construction in the county, whether new, remodeling, or additions, requires a county-issued building permit, regardless of whether the property is in a municipality or an unincorporated area.
Zoning and placement
Residential site disturbance, sewer or water service areas, sediment and erosion control, septic, DelDOT entrance permits, flood zones, and final zoning inspection can affect the permit path.
Building and trade review
The Building Code Office conducts plan review and inspections for single-family, multi-family, and commercial projects, and maintains inspection records through the Self Service Portal.
Discuss your project early when: Call before applying if the project includes new construction, addition, remodel, alteration, site disturbance, sewer or water connection, septic, flood zone work, or municipal property.

Permit and scope questions
Sussex County inspection guidance requires county-approved plans onsite and third-party reports submitted before certain inspections can be scheduled.
Zoning and placement
Final zoning inspection, final survey, lot grading, onsite wastewater, DelDOT entrance permits, and flood-zone documentation may be required before final approval.
Building and trade review
Residential inspection types include footing, pre-slab, setback, framing, energy, final, final zoning, manufactured home, and other project-specific inspections.
Discuss your project early when: Call before scheduling if the project involves flood-zone construction, piles, foundations, trusses, waterproofing, energy reports, septic, DelDOT entrance, final survey, or a project that only needs final zoning.
