Delaware Contractor & Trade License Requirements
Delaware does not require a statewide general contractor license but mandates contractor registration with the Division of Revenue. Specialty trades — electricians, plumbers, and HVAC technicians — are licensed statewide through the Division of Professional Regulation (DPR). Roofing contractors need only the general contractor registration. Delaware uses a master/journeyperson licensing structure for trades, with biennial renewals on even-numbered years.
