Concrete work — foundations, slabs, driveways, sidewalks — is construction of an improvement to real property, which makes the business a 'contractor' under 30 Del. C. § 2501. Delaware has no concrete trade license, exam, or experience requirement; the state layer is the Division of Revenue contractor license ($75 per year) backed by a workers' compensation certificate and a Department of Labor certificate of notice, plus the 0.6472% gross receipts license fee.
Nonresident concrete contractors file a 6% surety bond on contracts of $20,000 or more before starting (30 Del. C. § 375). Driveways and sidewalks are named home improvements in 11 Del. C. § 916, so residential flatwork falls under the home improvement fraud statute. Permits for structural concrete and right-of-way work are issued by counties and municipalities.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Delaware's contractor license is a state Division of Revenue license; it does not test competency and does not replace local requirements. The Division of Revenue says your city and/or county may also require its own business license, and building permits and inspections come from New Castle, Kent, or Sussex County or the municipality where the work is. Electrical work is inspected statewide by Board-licensed third-party inspection agencies (24 Del. C. § 1420), and counties and municipalities may adopt plumbing, HVACR, and fuel gas codes that do not conflict with state licensing law (24 Del. C. § 1832).
The local offices section below names the exact permit desk for every Delaware county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Delaware's contractor license comes from the Division of Revenue: a fee, workers' comp proof, and gross receipts filings — no exam and no experience requirement.
11 Del. C. § 916 lists driveways and sidewalks; misrepresentation or failing to apply a deposit to the job is a crime.
Out-of-state contractors file a 6% surety bond on $20,000+ contracts before construction (30 Del. C. § 375).
