Delaware Trade Licensing: No Statewide GC License

The two layers

• DPR trade licensing (Department of State). Division of Professional Regulation boards administer Master-level (and certain restricted) licenses for electrical, plumbing, and HVACR. Exam-based, competency-verified, under specific chapters of 24 Del. C. (the Delaware Code professions title).
• Revenue contractor licensing (Department of Finance). Every business doing contracting work in Delaware needs a contractor license issued by the Division of Revenue — Resident Contractor or Non-Resident Contractor, depending. This is revenue-focused (gross receipts tax hook) and business-identity-focused, not competency-focused.

A contractor doing general construction in DE — framing, drywall, interior finishes, concrete, roofing, etc. — needs the Revenue contractor license. That's the general-contractor analog, but it doesn't come from a licensing board, and it doesn't evaluate competency. It's a business/tax registration with a bond requirement for non-residents.

A contractor doing electrical, plumbing, or HVACR work in DE needs both layers: Revenue contractor license plus the trade-specific DPR Master license (or the trade work must be performed by someone holding the appropriate DPR license).

What DPR trade boards do

The Division of Professional Regulation (dpr.delaware.gov) houses multiple licensing boards. The construction-relevant ones:

• Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Issues Master HVACR (unrestricted) and Master HVACR Restricted licenses, plus Master Plumber licenses. Restricted variants are limited to specific specialties within the broader trade.
• Electrical licensing board. Master Electrician licensure — exam-based, experience-verified.

DPR runs applications through DELPROS, the state's online licensing system. Common requirements across boards:

• Documented experience — typically several years post-journeyman or equivalent supervised experience.
• Passing score on the trade-specific exam (administered by ProV or equivalent; typical passing threshold around 70-75%).
• EPA Section 608 certification for refrigerant handling where applicable.
• Verification of licensure from other jurisdictions where the applicant holds credentials.
• Licensure renewal on the board's cycle with continuing education requirements.

Reciprocity is verification-based rather than automatic. An out-of-state master credential gets verified, and the DE board determines whether additional exam is required. The answer depends on the credentialing state. A PA master electrician's municipal license, for example, may trigger the DE exam requirement because PA doesn't have a statewide master license with equivalent scope. A MD master plumber's state credential is evaluated on its own terms.

What Revenue contractor licensing does

The Division of Revenue contractor license is the business-side layer. The structure:

• Resident Contractor. DE-based business with a physical place of business in Delaware. License fees historically around $200 (non-bidding) or $300 (state-contract-bidding). Workers' compensation and unemployment insurance documentation required.
• Non-Resident Contractor. Business based outside DE. Surety bond required in addition to the above. The bond protects gross receipts tax collection and compliance with DE requirements.

Revenue doesn't evaluate trade competency. It's:

• Gross receipts tax registration.
• Business identity verification.
• Bond posting (non-residents) to secure tax compliance.
• Connection to DE unemployment and workers' comp systems.

This is the layer every DE contractor has regardless of trade.

How they interact

A few clean project-type mappings:

• General construction / remodeling (no regulated trade work). Revenue contractor license required. No DPR trade license required unless employing individuals doing regulated trade work — in which case those individuals need DPR licensure.
• Electrical-only contractor. Revenue contractor license + DPR Master Electrician license (either by the principal or by employees performing the work under proper supervision structure).
• Plumbing-only contractor. Revenue + DPR Master Plumber.
• HVACR-only contractor. Revenue + DPR Master HVACR (or appropriate restricted category).
• GC with in-house trade work. Revenue contractor license + DPR Master licenses for each trade performed in-house.
• GC subcontracting out all trades. Revenue contractor license. Subs independently hold DPR + their own Revenue licenses.

What this catches for neighboring-state contractors

Each neighboring state has a different mental model, and none of them ports cleanly:

• Maryland contractors crossing into DE. MD has MHIC (exam-based, competency) for home improvement and MD trade boards for regulated trades. Crossing into DE: MHIC doesn't transfer, MD trade credentials get evaluated by DPR (not automatic reciprocity), and Revenue contractor license as a Non-Resident Contractor is mandatory.
• Pennsylvania contractors crossing into DE. PA's HIC (AG-administered, consumer-protection-focused — see our PA HIC essay) doesn't substitute for anything in DE. PA municipal electrical licenses (Philadelphia, for example) generally trigger DE exam requirements because PA lacks a statewide master framework with matching scope. Revenue contractor license as non-resident is required.
• New Jersey contractors crossing into DE. NJ's three tracks (HIC + DORES + trade boards — see our NJ Three Tracks essay) don't transfer. DE trade board evaluates NJ trade credentials; Revenue contractor license non-resident required.
• Virginia contractors crossing into DE. VA's Class A/B/C framework (see our VA Class A/B/C essay) doesn't transfer. VA trade designations evaluated by DPR boards individually.

Public works overlay

A contractor bidding DE public works needs both layers plus DE's prevailing wage posture — per-project rate requests through the Department of Labor. See our DE Per-Project Rate Timeline essay for the prevailing-wage workflow. The licensing foundation (DPR + Revenue) is independent of the public-works rate path; all layers attach.

Common missteps

• Asking "where do I get the DE general contractor license?" There isn't one. The Revenue contractor license is the business-side analog.
• Assuming home-state trade credentials transfer automatically. DPR verifies; does not rubber-stamp.
• Missing the Non-Resident Contractor surety bond. Required for out-of-state businesses; not optional.
• Skipping Revenue registration for "just a small job." The Revenue license is required for doing contracting work in DE, not calibrated to job size.
• Confusing a resident place-of-business requirement with a mailing address. Resident Contractor needs a real DE place of business; out-of-state firms with a DE mail drop don't qualify.
• Using the Revenue license as evidence of trade competency. It's a tax/business registration, not a trade license. Different thing.

What to do with this

If you're a DE contractor: inventory which of the two layers you have and which you need given your scope of work. Both are usually required.

If you're crossing into DE from a neighbor: start with DPR trade license verification and Revenue Non-Resident Contractor application in parallel. Both take time; don't sequence serial.

If you're a GC managing regulated-trade subcontractors in DE: confirm each sub holds DPR trade licensure + Revenue contractor license. Paper verification is cheap; discovery mid-project isn't.
