Delaware wrote the employment relationship into the statute itself. The exemption that legalizes your entire unlicensed crew requires a master who is their employer or a full-time employee of the same business entity, and losing that person starts a 100-day countdown to cease and desist.
Most states leave the relationship between a company and its license holder vague. They say the licensee must be an "officer," or in "responsible charge," or a "qualifying party," and then leave everyone to argue about what that means in practice.
Delaware did not do that. Delaware wrote the employment relationship into the exemption itself, in one sentence, twice.
Here is 24 Del. C. § 1807(c)(1), the plumbing exemption:
"The individual is an apprentice, journeyman, mechanic, or other person providing such services under the supervision of a master plumber who is the individual's employer or who is employed full time by the same business entity as the individual."
And here is § 1820(c)(1), the HVACR exemption, word for word in structure:
"The individual is an apprentice, journeyman, mechanic or other person providing such services under the supervision of a master HVACR licensee or master HVACR restricted licensee, who is the individual's employer or who is employed full time by the same business entity as the individual."
That is not guidance. That is not a board policy that could change next year. It is the statutory condition on which your entire unlicensed workforce's right to work depends, and it names full-time employment as the test.
This article is about what that sentence does to a Delaware contracting business — and why, in this state more than most, a license arrangement that is anything other than genuine full-time employment simply does not survive contact with the statute.
Why the exemption is the whole ballgame
Delaware licenses only masters in plumbing and HVACR. There is no state journeyman license and no state apprentice license in either trade. (See Plumbing License Delaware and HVAC License Delaware for the full ladders — or rather, the absence of them.)
That means every single person on your plumbing or mechanical crew who is not personally a licensed master is working under an exemption. Not under a lesser license. Under an exemption.
And § 1807(a) is blunt about the default rule: a person shall not provide plumbing services in Delaware "unless the person has been licensed as a master plumber under this chapter, or exempted from the provisions of this chapter pursuant to subsection (c)." § 1820(a) says the same for HVACR.
So the question is never "is my crew licensed." It is "does my crew fit the exemption." And the exemption has exactly two components: supervision by a master, and an employment relationship between that master and the worker.
Fail the second component and the first does not save you. A master can supervise your crew all day long, competently and in good faith, and if he is neither their employer nor a full-time employee of the same business entity, the exemption in § 1807(c)(1) does not describe them.
What "the same business entity" rules out
The statute gives you two acceptable configurations:
- The master is the individual's employer. The classic owner-operator: the licensed master owns or runs the shop and the crew works for him.
- The master is employed full time by the same business entity as the individual. The master and the crew are both employees of the same company.
Notice the word doing the work in the second one. Not "engaged by." Not "affiliated with." Not "retained by." Employed full time by.
That language does not describe:
- A master plumber who holds the license for your company while working full time somewhere else.
- A master who is paid a monthly retainer as an independent contractor and issued a 1099.
- A master compensated per project, per permit, or as a percentage of jobs he qualified.
- A master who is on your books as a part-time employee.
- A master who is "on paper" as a consultant, advisor, or officer without an actual full-time employment relationship.
None of those are full-time employment by the same business entity. And because Delaware put the test in the exemption rather than in a licensing form, the consequence of failing it does not land on a renewal application eighteen months later. It lands on every job your crew is working right now.
We cover the broader version of this question in Can a Qualifying Agent Be a 1099 Contractor? and Contractor License Qualifier: Owner vs. Employee. Delaware is the cleanest statutory example of why the answer is what it is.
The second door: allowing another person to use your license
Suppose someone proposes the arrangement anyway. The statute closes that door from the licensee's side too.
§ 1814(a)(1) (plumbing) makes a licensee subject to discipline where the licensee has "engaged or knowingly cooperated in fraud or material deception in order to acquire a license, has allowed another person to use that individual's license, or has aided or abetted an unlicensed to represent oneself as an individual licensed pursuant to this chapter."
§ 1827(a)(1) says the same thing for HVACR licensees.
So the exposure is two-sided and asymmetric in an important way. The company risks the unlicensed-practice penalties under § 1807(d) and § 1820(d) — not less than $1,500 and not more than $3,000 for a first offense, not less than $3,000 and not more than $6,000 for a second or subsequent offense, with Justice of the Peace Court jurisdiction. The master risks the thing he spent seven years earning.
Board sanctions under § 1815 and § 1828 include a letter of reprimand, censure, probation, suspension, revocation, and an administrative penalty of up to $500 per violation. A finding requires the affirmative votes of five or more Board members, and the licensee may appeal to Superior Court within 30 days.
And the enforcement trigger is not discretionary. Under § 1813(b) and § 1826(b), where the Board determines a person is providing services or using a protected title contrary to the chapter, the Board shall request that the Attorney General's Office issue a cease and desist order, prosecute the person, or both.
This is the Delaware-specific reason the arrangement people describe as "renting a license" does not work here. It is not merely risky or frowned upon. It is a named ground for discipline against the licensee and a fined offense for the company. The general treatment is in Is It Legal to Rent a Contractor License?
The 100-day clock: what happens when you lose your license holder
Delaware then does something almost no other state does. It writes out, in statute, exactly what happens to a company that loses its only licensed master — and it puts a hard deadline on it.
§ 1831, "Artificial entity's loss of license holder," applies to any partnership, firm, corporation or other artificial entity providing services regulated under Chapter 18. The sequence:
- Day 0 — the loss. Your sole license holder resigns, retires, dies, or has their license suspended or revoked.
- Within 7 days. The entity shall notify the Board in writing, with supporting documentation, of the loss. Seven days. Not thirty.
- Within 10 days of that notification. The Board shall schedule an emergency meeting.
- In the gap. From the date of loss through the date of the emergency meeting, the entity may continue to operate without a license holder — but only "provided that the entity continues to employ the same personnel with the exception of the license holder." Keep your crew intact or lose the grace period.
- Before the emergency meeting. An owner or employee of the entity who wants to keep the business running must submit an application for licensure to the Board in time for consideration at that meeting.
- At the meeting. The Board may issue a temporary license, valid for 100 days, dated from the date you notified the Board — not from the date of the meeting. Delay in reporting eats your own clock.
- After that. The temporary licensee must take the next available examination. The temporary license expires immediately upon failure to take that next available exam, or upon the Board's receipt of notification that the applicant failed it.
- At expiry. If the 100-day temporary license expires and the entity has no license holder in its employ, the entity "must cease and desist immediately" from providing services for which a license is required.
Read that as an operations problem rather than a legal one and the picture is stark. A Delaware plumbing or mechanical company that loses its master has, at the outside, about three and a half months to either produce a newly licensed owner or employee, or stop working.
And look at who § 1831(c) says can be handed the temporary license: "An owner or employee of an entity that desires to continue providing services." Not a contractor. Not a consultant. Not an outside licensee willing to lend a number. The statute's own emergency valve is restricted to people already inside the business — which is entirely consistent with § 1807(c)(1) and § 1820(c)(1). Delaware is internally coherent on this point in a way many state statutes are not.
One drafting note worth flagging honestly: § 1831 sits in Subchapter IV (Miscellaneous Provisions) and is expressly cross-referenced by the HVACR exemption at § 1820(c)(4), but the cease-and-desist language in § 1831(f) refers specifically to "plumbing services." If you are on the mechanical side and this provision is about to matter to you, confirm the Board's current application of it directly rather than relying on the literal subsection text.
The layer that fools people: the $75 business license
Here is where owners most often talk themselves into trouble.
Delaware issues contractor business licenses through the Division of Revenue under 30 Del. C. Chapter 25. Under § 2502(a) the fee is $75, renewed annually on or before December 31. It is easy to get. It arrives quickly. It has the word "license" on it.
And the Division of Revenue's own published contractor guidance says this about it:
"The Business License Issued by the Division of Revenue is not a regulatory license and the issuance of such license does not attest to the qualifications of the applicant to perform the activity described on such license."
The state is telling you plainly: this document says you registered and you are on the hook for gross receipts tax. It says nothing about whether anyone at your company is competent or licensed to do the work.
The Division of Revenue guidance even points you down the hall — "The State of Delaware also has a Division of Professional Regulations. Many occupations and some types of equipment have regulatory requirements."
So Delaware has two layers, in two agencies, under two titles of the code:
- The business layer — Division of Revenue, 30 Del. C. Ch. 25. A $75 annual license, gross receipts tax at the Division's published contractor rate of 0.6537% with the first $100,000 per month excluded, a workers' compensation certificate, a Department of Labor certificate of notice, and for nonresident contractors a surety or cash bond equal to 6% of the total of all contracts exceeding $20,000. Attaches to the company.
- The competence layer — Division of Professional Regulation, 24 Del. C. Ch. 18. The Master Plumber or Master HVACR license, earned through two or seven years of supervised experience and a 70% exam. Attaches to a person.
Fees, rates, thresholds and bond percentages are set by the Division of Revenue and by statute and are subject to change — verify current figures with the agency.
You can complete the entire business layer in an afternoon and still be legally unable to send anyone to a jobsite. That gap — between "I have a Delaware contractor license" and "I have a licensed master employed full time" — is where most of the trouble in this state lives. For the general version of that distinction, see State vs. Local Contractor License.
Why licensed masters are scarce, and what that does to the market
There is a supply asymmetry buried in all of this that is worth stating plainly.
A company can employ many masters. A master can only be full-time employed by one business entity at a time — that is what full-time means, and it is what § 1807(c)(1) and § 1820(c)(1) require. So the relationship is one-to-one on the licensee's side and one-to-many on the company's side.
Layer on Delaware's licensing structure and the pool gets thin fast. Because there is no journeyman license, the only credential that qualifies anyone to hold a company's compliance is the master license. Because reaching it requires either a federally-approved apprenticeship plus two supervised years, or seven supervised years plus a bypass exam, plus a 70% exam, plus — on the refrigerant tracks — EPA CFC certification, the pipeline is slow. And because three exam failures triggers a one-year lockout and a fresh application under Board Regulations 2.2.2 and 3.1.6, the pipeline is also lossy.
Delaware is a small state with a small licensee roster. When an owner in Wilmington or Dover suddenly needs a Master Plumber, the pool of people who are both qualified and available to be a full-time employee is not large.
That is the market qualifying agents exist to serve, and it is why the honest answer to "what does it cost" is that it depends on the situation rather than a rate card. What actually moves it: the license class you need, whether it is a full Master HVACR or a specific Restricted specialty, how fast you need the person seated, the risk and volume of the work, whether you need one state or several, and how long the arrangement runs. Because Delaware requires genuine full-time employment, a placement is a real payroll commitment, not a fee for the use of a number. If that is the conversation you need to have, Consultation Packages is where it starts.
How compliant placement actually works
The Licensing Company places qualifying agents as full-time W-2 employees of the client business. Not as contractors, not on a percentage, not per project. That is not a stylistic preference. In Delaware it is the only configuration the statute describes.
In practice:
- The master plumber or master HVACR licensee becomes a W-2 employee of the contracting entity, on payroll, with the tax treatment and documentation that implies.
- That satisfies § 1807(c)(1) or § 1820(c)(1) directly — the master is "employed full time by the same business entity" as the crew working under supervision.
- It keeps the licensee clear of § 1814(a)(1) and § 1827(a)(1), because nobody is "using" anyone's license. The licensee is an employee of the company whose work he supervises.
- It positions the company for § 1831 if things go wrong later, because the emergency temporary license is available only to an owner or employee.
- And it produces the documentation you actually need if the Board ever asks: a W-2, a payroll record, an employment file. The same evidence the Board accepts for proving experience under its own Verification of Employment process.
If you hold a Delaware master license and want to understand what serving in this role involves, see Become a Qualifying Agent. If you are running the company and need one placed, Hire a Qualifying Agent covers the process. If the whole concept is new, start with What Is a Qualifying Agent?
How Delaware compares
Delaware is not alone in tying the license to an employment relationship, but it is unusually explicit about it, and the comparison is instructive:
- Omaha, Nebraska requires a master plumber who is a full-time employee — but by city ordinance, not state statute, because Nebraska has no state plumbing license at all. See Omaha's Master Plumber Rule.
- Montana requires a designated master plumber of record for the business, documented in writing. See Montana's Master Plumber of Record.
- West Virginia requires the qualifying individual to be part of responsible management or a full-time employee, and limits a license holder to one business entity at a time. See West Virginia's Qualifying Individual Rule.
- Delaware puts the full-time employment test in the exemption that legalizes your entire unlicensed workforce, in both trade subchapters, and backs it with a statutory 100-day wind-down clock if you lose the person.
Different mechanisms, same underlying reality: states that take licensing seriously do not let a company rent competence. They require it to employ it. For a broader treatment of how boards describe the role, see Qualifying Agent vs. Responsible Managing Employee.
Frequently asked questions
Can a Delaware master plumber qualify a company he does not work for? No. § 1807(c)(1) exempts unlicensed workers only where the supervising master is their employer or is employed full time by the same business entity. A master employed full time elsewhere cannot satisfy that test for your crew, and § 1814(a)(1) makes allowing another person to use your license a ground for discipline.
Can a qualifying agent in Delaware be paid on a 1099? The statute conditions the exemption on the master being the worker's employer or a full-time employee of the same entity. An independent-contractor relationship documented on a 1099 is by definition not full-time employment by the entity. Delaware's own emergency provision, § 1831(c), reinforces the point by limiting the temporary license to an owner or employee.
Can one master hold licenses for two Delaware companies? The statutory test is full-time employment by "the same business entity" as the supervised workers. A person cannot be a full-time employee of two entities simultaneously in any meaningful sense, so the practical answer is no. Confirm your specific facts with the Board before structuring anything unusual.
What happens the day my licensed master quits? The § 1831 clock starts. Notify the Board in writing with supporting documentation within 7 days. The Board holds an emergency meeting within 10 days of that notice. You may keep operating until the meeting if you keep the same personnel otherwise. An owner or employee must file a licensure application before the meeting to be considered for a 100-day temporary license, dated from your notification. That person must sit the next available exam; the temporary license dies immediately if they skip or fail it. When the 100 days run out with no license holder employed, you must cease and desist immediately.
Does the Division of Revenue contractor license let me do plumbing or HVAC work? No. The Division of Revenue states in its own contractor guidance that the business license "is not a regulatory license" and "does not attest to the qualifications of the applicant." It registers you and starts your gross receipts tax obligation. The authority to perform licensed trade work comes only from a Division of Professional Regulation master license held by a person.
How much does a Delaware qualifying agent cost? There is no standard figure, and any site quoting one is guessing. The variables are the license class, the urgency, the risk and volume of the work, the number of states involved, and the duration. Because Delaware requires full-time employment, the arrangement carries real payroll cost rather than a flat licensing fee, and it is scoped per situation. Consultation Packages is the starting point.
Is a part-time master enough? No. The statute says "employed full time by the same business entity." Part-time employment does not meet the text of § 1807(c)(1) or § 1820(c)(1).
