Delaware general contractor licence: what there is to verify

Delaware does not license general contractors. A construction business needs a Division of Revenue business license, which is a tax registration — it is issued on payment, tests nothing, and says nothing about whether the holder can build. There is no state competency licence to verify and no register that will confirm one.

What you can check instead

What is verifiable: the licensed trades on the job. Delaware licenses master electricians, master plumbers, HVACR masters and elevator mechanics as individuals, and this API checks any of them in one call. Ask a Delaware general contractor for the names and licence numbers of the tradespeople doing the regulated work, and verify those — that is the whole of what can actually be confirmed in this state.

What Division of Professional Regulation does not publish

Full coverage detail, including the caveats that apply to every Delaware lookup, is on the Delaware page.
