Contractor Licensing Requirements in Delaware

Delaware is one of the few states with no trade-specific general contractor license. Instead, contractors register for a business license through the Division of Revenue and pay a gross-receipts tax on construction work. Certain trades — electrical, plumbing, and HVACR — do require a separate state license issued by their own licensing boards under the Division of Professional Regulation (DPR).

Delaware’s Contractor Licensing System

There is no statewide “general contractor” credential in Delaware — general/building contractors operate under a Contractor’s Business License from the Division of Revenue rather than a trade-competency license, and must also register with the Delaware Department of Labor’s Office of Contractor Registration. Trade contractors are the exception: electricians are licensed by the Board of Electrical Examiners, and plumbers/HVACR technicians by the Board of Plumbing, HVACR, Examiners, both under DPR. In practice this means a Delaware GC needs a tax registration, not an exam-based license, while specialty trades still face real testing standards.

License Classes in Delaware

• Contractor’s Business License (Division of Revenue) — required for general/building contractors; not trade-competency tested, functions as a tax registration
• Electrician licenses (Board of Electrical Examiners): Apprentice, Journeyperson, Residential, Limited, Limited Special, and Master Electrician
• Plumbing/HVACR licenses (Board of Plumbing, HVACR, Examiners): journeyperson and master-level credentials for plumbers and HVACR technicians
• Non-resident contractor registration — out-of-state contractors doing $20,000+ in Delaware work must also post a surety bond

Exam & Experience Requirements

General/building contractors face no state trade exam — the business license is issued on registration and payment of fees. Electricians do face real testing: Journeyperson requires 8,000 hours of supervised experience, Residential requires 4,000 hours, and Master Electrician requires 6 years of practical experience (or 4 years of schooling plus 2 years of practical experience) plus a written exam scored on a 75% pass threshold, with exam fees around $100.

NASCLA Reciprocity

Delaware is not a NASCLA-participating state, so a NASCLA Accredited Examination credential cannot be substituted for Delaware’s own trade board exams — contractors moving from a NASCLA state still need to meet Delaware’s specific board requirements for electrical, plumbing, or HVACR work.

Bonding & Insurance to Get Licensed

Non-resident contractors must post a surety bond equal to 6% of the contract price once a single contract, or the aggregate of contracts in a calendar year, reaches $20,000 or more; resident general contractors are not bond-required at the state licensing level. General liability and workers’ compensation coverage are still expected as standard business practice and are often required by clients, GCs, or municipalities even though Delaware’s business license itself doesn’t set a minimum.

Reciprocity with Other States

Because Delaware has no general contractor exam, there’s effectively nothing to reciprocate for GCs beyond registering for the business license. Electrical and plumbing/HVACR licensees from other states do not get automatic reciprocity and must apply through the relevant DPR board and meet its specific experience/exam requirements.

Penalties for Unlicensed Contracting

Delaware’s licensing boards can issue cease-and-desist orders and impose fines for unlicensed practice under the Administrative Procedures Act, and operating without the required Division of Revenue business license can trigger separate tax-compliance penalties; consumers also have recourse under the Delaware Consumer Fraud Act (Del. Code Title 6, Ch. 25, Subch. II, §§2511–2527) for deceptive contracting practices.
