Getting your Delaware license starts here...
In Delaware, there is no single statewide general contractor license. Instead, all contractors must first obtain a Delaware business license from the Division of Revenue, and nonresident contractors are often required to post a tax compliance bond on larger projects. Trade licensing — including electrical, plumbing, and HVACR contractors — is regulated by the Delaware Division of Professional Regulation (DPR).
Requirements vary depending on license type, but may include verified experience, passing state trade exams, proof of liability insurance, and bonding for nonresident work. Municipalities may also set additional rules for permits or specialty work.
Contractor Licensing Inc. makes the Delaware process easier.

RECIPROCAL STATES
Delaware Contractor License Reciprocity
Delaware does not maintain broad reciprocity agreements for contractor licenses. Most contractors must meet Delaware’s requirements and pass the state exam.
Electrical & Plumbing: The DPR may allow license by endorsement if another state’s licensing standards are substantially similar, but this is evaluated case-by-case. Applicants should not assume reciprocity.
