Plumbing License Arkansas: The Board That Doesn't Exist, and What Actually Licenses You (2026)

If you search for how to get a plumbing license in Arkansas, the page that ranks tells you the credential is "administered by the Arkansas State Plumbing Board" and is "governed under Arkansas Code Annotated § 17-38." One of those is right. The other names an agency that does not exist.

There is no Arkansas State Plumbing Board. There is no Arkansas State Board of Plumbing Examiners either, which is the second name the same site uses on its own sidebar. Arkansas plumber licensing sits with the Arkansas State Board of Health, is administered day to day by the Plumbing and Natural Gas Section of the Arkansas Department of Health, and eligibility decisions are made by the State Committee of Plumbing Examiners. That is the language the Department uses in its own rules, and if you write to the wrong agency your application does not get slower, it goes nowhere.

That distinction matters more in Arkansas than it does in most states, because Arkansas does something unusual: it puts plumbing and natural gas under the same section, the same rules, and the same experience requirement. When the Department asks a journeyman applicant to document four years of experience, it asks for four years "in all phases of plumbing and natural gas." Gas is not a bolt-on endorsement here. It is part of the license.

This guide covers the license ladder, what each step actually costs, the two different renewal calendars that catch people out, and — the part almost nobody publishes — how the Health Department plumbing license connects to the separate contractor license issued by a completely different agency.

Who regulates plumbing in Arkansas

The authority chain runs like this. Act 200 of 1951, as amended, and Ark. Code Ann. § 17-38-101 et seq. give the Arkansas State Board of Health the power to license plumbers. The Board's current rules — Rules Pertaining to Master, Journeyman, and Restricted Plumber Licenses, Plumbing and Gas Inspector Licenses, Restricted Hospital Maintenance, Water and Sewer Service Line Installation — took effect September 5, 2024.

The operating office is:

• Arkansas Department of Health, Plumbing & Natural Gas Section
• 4815 West Markham Street, Slot #24, Little Rock, AR 72205-3867
• Phone (501) 661-2642

The State Committee of Plumbing Examiners is the body the rules name as responsible for determining "eligibility of applicants for various types of plumbing and gas licenses." It is the Committee that decides whether your experience documentation is good enough, whether you sit an exam, and whether a lapsed license comes back with or without a retest.

Two things follow from this that competing guides get wrong. First, there is no separate "plumbing contractor license" issued by a plumbing board — Arkansas has no plumbing board. Second, the claim that a plumbing contractor is "the only entity authorized to legally contract for plumbing services in Arkansas" ignores the Arkansas Contractors Licensing Board entirely. More on that below, because it is the step that actually determines whether you can bid work.

The Arkansas plumber license ladder

Arkansas licenses four things at the individual level: apprentice, journeyman, master, and a family of restricted licenses. The rules define each one in plain terms.

Apprentice Plumber. The rules define an apprentice as "a person other than a Master, Journeyman, or Restricted license holder who is registered under an Arkansas Master Plumber and enrolled in the Apprentice Plumber training program outlined in Ark. Code Ann. §17-31-401, et seq." Note the two conditions — you are registered under a named Arkansas Master Plumber, and you are enrolled in the program. Registration alone is not the credential.

Journeyman Plumber. Defined as "any person other than a Master Plumber, who is engaged in the practical installation of plumbing." The eligibility bar is a minimum of four years of experience or its equivalent. An apprentice who completes an Arkansas apprenticeship under Ark. Code Ann. § 17-38-409 is considered for the journeyman examination on that basis.

Master Plumber. Defined as "any person skilled in the planning, superintending and the practical installation of plumbing and who is familiar with the laws, and rules governing the same." Note the verbs — planning and superintending, not just installing. That is supervisory language, and it is why the master license is the one a business needs. Eligibility requires five years of experience, and separately, you must hold a Journeyman license for one full year before you are eligible for the Master exam. The Committee may waive the one-year requirement "in whole or in part" in cases of extreme hardship — but that is a discretionary exception, not a route to plan around.

There is one other door into the Master exam: the rules allow the Committee to "consider applicants for Master Plumber examination who are professional engineers with special expertise in plumbing engineering."

Restricted Plumber. This is a set of narrow licenses "limited to gas fitter, governmental maintenance, service line installation, solar mechanic and hospital maintenance licenses," each granted only where the applicant "has demonstrated competency for the particular phase of plumbing for which the person is licensed."

Restricted licenses carry a trap that is worth reading twice. Experience earned under a Restricted Hospital Maintenance Plumber's License or a Restricted Water and Sewer Service Line Installation Plumber's License is not eligible to be used as credit toward other forms of licenses issued by the Department. Four years installing service lines under a restricted license does not become four years toward a journeyman card. And restricted licenses cannot be transferred from one phase to another — you file a new application.

What the Arkansas application actually asks for

The journeyman application form is short and specific, and two lines on it tell you how Arkansas thinks.

The first is: "Arkansas Master Plumber under which you will be working" — name and license number. A journeyman applicant is expected to identify a licensed Master. Arkansas builds the supervisory relationship into the application itself rather than leaving it implied.

The second is the documentation rule, printed in bold on the form: "Application will be DENIED without submitting the required documentation. Documentation must accompany the application. DO NOT SEND SEPARATELY."

For an applicant coming out of an Arkansas apprenticeship, the required document is an Arkansas Apprenticeship Committee Release form endorsed by the training program. For an applicant with no license and no apprenticeship, it is documentation of at least four years of experience "in all phases of plumbing and natural gas." The Committee of Plumbing Examiners "will consider affidavits, bona fide evidence from licensing agencies, or qualified former employers who can attest to the applicant's work background as a plumber."

Other application facts worth knowing before you start:

• The application must be notarized — signed and sworn before a notary.
• A Social Security Number is required. The form states the agency is required to obtain it for child support enforcement, and that outside that use it will be held confidential.
• The Board of Health is not authorized to conduct criminal background checks, but it may ask about convictions at application and renewal. Providing false information is itself grounds for suspension, revocation or denial.
• Under Act 990 of 2019 you can file a pre-licensure determination petition to find out in advance whether a criminal record will disqualify you, and whether a waiver is available. The response is in writing, states its reasons, and is not subject to appeal.
• The Department will issue a temporary revocable permit or provisional license for 90 days on request once the Committee approves your eligibility, extendable on a hardship finding.

Arkansas plumbing license fees

These are the Department's published figures under the rules effective September 5, 2024. Fees are set by the Board and change — verify the current schedule with the ADH Plumbing & Natural Gas Section before you write a check.

Application fees (paid with the application; the form states applications are not reviewed without fees):

• Master, Restricted Supervisor Solar Mechanic, Restricted Residential Maintenance, Restricted Governmental Maintenance, Restricted Supervisor Hospital Maintenance, Restricted Water and Sewer Service Line Installation, and Restricted Supervisor Gas Fitter — $125.00
• Journeyman, Restricted Gas Fitter, Restricted Hospital Maintenance, Restricted Solar Mechanic — $75.00
• Additional examination after a failure, or after failing to appear without proper notification — $50.00
• Non-scheduled or oral examination — an additional $50.00 per exam

Annual license fees:

• Master Plumber, Restricted Supervisor Solar Mechanic, Restricted Residential Maintenance, Restricted Water and Sewer Service Line Installation — $200.00
• Restricted Supervisor Gas Fitter — $200.00
• Restricted Gas Utility License — $200.00
• Journeyman Plumber, Restricted Solar Mechanic, Restricted Gas Fitter — $75.00
• Restricted Governmental Maintenance, Restricted Supervisor Hospital Maintenance — $100.00
• Restricted Hospital Maintenance — $37.50
• Apprentice, Restricted Gas Fitter Trainee, Restricted Hospital Maintenance Trainee, Restricted Solar Mechanic Trainee, Plumbing or Gas Inspector registration — $25.00
• Gas Utility Serviceperson — $25.00

Inspection fees: $25.00 per inspection, and $35.00 for each additional inspection caused by the negligence of the Supervisor license holder. That second figure is a penalty priced into the fee schedule, and it is charged to the license holder, not the crew.

Fee waiver. Under Act 725 of 2021, an applicant can have the initial licensure fee waived if they receive Medicaid, SNAP, WIC, TEA or Lifeline assistance; were approved for unemployment in the last twelve months; or have income at or below 200% of the federal poverty guidelines. You must provide documentation from the issuing agency and attest that it is genuine — fraudulent documentation is grounds for denial or revocation.

The two renewal calendars — this is where people lose licenses

Arkansas does not run one renewal date. It runs two, and they are six months apart.

Master, Journeyman and Apprentice licenses expire annually on December 31. They must be renewed by February 1. After February 1, a penalty of $5.00 per month is added.

All Restricted Plumber licenses expire annually on June 30. They must be renewed by August 1, with the same $5.00 per month penalty after that date. Plumbing and Gas Inspector certificates run on the same June 30 / August 1 calendar.

If you hold a Master license and a Restricted Gas Fitter license, you have two renewal deadlines in the same year. That is the single most common way an Arkansas plumber ends up unknowingly working on a lapsed credential.

Deferment is available for Master and Journeyman holders at $20.00 per year — the license goes inactive rather than lapsing. Members of the armed services and their spouses get deferment without regular or reinstatement fees, and a Master or Journeyman who becomes an appointed or employed Plumbing Inspector may be granted a courtesy deferment on the same basis.

Reinstatement after a lapse is expensive. The rules set a reinstatement fee of $325.00 for a Master Plumber license and $150.00 for a Journeyman Plumber license, in addition to any back fees and penalties. Reinstating a deferred license, by contrast, costs the current license fee plus a $20.00 reinstatement fee. The gap between $20 and $325 is the entire argument for deferring rather than letting it go.

Reinstatement also requires "an amended experience record covering all experience subsequent to the date of the lapse," and the Department decides whether to reinstate with or without examination. Past five consecutive years of delinquency, that decision goes to the Committee of Examiners.

Transfer. A Master may step down to a Journeyman license for a $20.00 transfer fee. A Journeyman who previously held an Arkansas Master license can go back up without examination for the $20 transfer fee plus the cost of the Master license — unless more than five years have passed since the transfer down, in which case an amended experience record is required and the Committee decides whether to test you.

Scope discipline: using the license for work it does not cover

The rules are blunt about this. "The use of a Master, Journeyman or Restricted Plumber's License to do plumbing other than permitted by the license shall be grounds for automatic suspension and/or revocation of such license." The same automatic-suspension language is repeated separately for hospital maintenance and for water and sewer service line licenses.

Restricted Water and Sewer Service Line holders get an especially tight fence: "In no instances shall this license be used to install, repair, or replace any portion of the water distribution or building drain system," and "This license does not include any portion of the natural gas service or system."

The Department may also suspend any license for non-payment of fees, or where the licensee fails to obtain annual training required by the rules.

Where the contractor license comes in

Here is the part the ranking pages skip, and it is the part that decides whether you can bid a job.

An ADH plumbing license lets you perform plumbing work. It does not, by itself, let you contract for construction work above Arkansas's dollar thresholds. That is a separate credential from a separate agency: the Arkansas Contractors Licensing Board, which sits under the Arkansas Department of Labor and Licensing at 4100 Richards Road, North Little Rock.

The thresholds are set out in the Board's own application affidavit and instructions:

• Residential contract work of $2,000.00 or more, including labor and materials, requires a residential license (Residential Builder, Residential Remodeler, or Home Improvement, depending on the work).
• Commercial work requires a commercial license. A Restricted Commercial license limits you to commercial projects under $750,000 including labor and material; an Unrestricted Commercial license carries no project ceiling.
• A commercial license automatically qualifies you to do residential work in the same classification or specialty listed on the commercial license.

And here is the link back to your plumbing card. On the Contractors Licensing Board's commercial application, the seven major classifications include "Mechanical (Plumbing & HVACR)" and "Electrical" — and both are flagged with a double asterisk meaning they "require an Arkansas Trade License or Certification." Major classifications require five years of documented experience; specialties require one.

In other words: the Health Department master plumber license is the trade credential that unlocks the Mechanical classification at the Contractors Licensing Board. You need both. Neither substitutes for the other. That is the structure, and getting it backwards is the most expensive mistake a growing Arkansas plumbing company makes.

The commercial application also requires a $10,000 Contractor's Bond in the principal name and EIN as registered with the Secretary of State, a compiled financial statement from an independent CPA, and a passing score on the Arkansas Business and Law exam, administered by PSI at an $84.00 examination fee — open book, multiple choice, 50 questions, two-hour limit, tested only from the NASCLA Contractors Guide to Business, Law and Project Management, Arkansas Edition. (PSI fees are set by the testing vendor and change; verify with PSI before registering.)

Who signs for the company

Every Arkansas Contractors Licensing Board application asks the same question about one specific human being: the person who took the Business & Law exam. It asks for their name, their Social Security Number, how long that individual has been with the company, and then it asks them to check exactly one of three boxes:

• Sole Owner
• Full time paid employee
• Officer, member, or partner of the company and is actively involved in the day-to-day operations

Three boxes. No fourth. And elsewhere in the same application, Arkansas uses the word directly — the instructions define "You/Your" as "this organization, any officer, the qualifier of this company, you, or anyone who owns 10% or more of the entity."

If the licensed individual behind your company is not an owner and not an officer, Arkansas has exactly one box left for them, and it says full time paid employee. That is the arrangement, and it is why every qualifier The Licensing Company places is placed as a W-2, full-time employee of the client's business — never a percentage arrangement, never a flat per-project fee, never a 1099. We have written up how this plays out across state lines in Does a Contractor License Qualifier Have to Be an Owner or an Employee? and, for the specific question people ask most, in Can a Qualifying Agent Be a 1099 Contractor?.

The full Arkansas picture — the three boxes, the tenure question, the 10% disclosure threshold, and how the trade-level supervisory roles feed it — is broken down in Arkansas Contractor License Qualifier: The Three Boxes on the Form.

Frequently asked questions

Is there an Arkansas State Plumbing Board? No. Arkansas plumber licensing is issued under the authority of the Arkansas State Board of Health, administered by the Plumbing & Natural Gas Section of the Arkansas Department of Health, with eligibility determined by the State Committee of Plumbing Examiners. Any guide naming an "Arkansas State Plumbing Board" or an "Arkansas State Board of Plumbing Examiners" is naming an agency that does not exist, and you should treat the rest of that page with the same suspicion.

How long does it take to become a master plumber in Arkansas? Five years of experience, and you must hold an Arkansas Journeyman license for one full year before you are eligible for the Master examination. The journeyman step itself requires four years of experience or its equivalent. The Committee of Plumbing Examiners may waive the one-year journeyman holding period in whole or in part in cases of extreme hardship, but that is discretionary.

Do I need a separate license for natural gas work in Arkansas? Not for ordinary plumbing-and-gas work under a Master or Journeyman license — Arkansas bundles them, and the journeyman experience requirement is written as four years "in all phases of plumbing and natural gas." Separate Restricted Gas Fitter, Restricted Supervisor Gas Fitter, Gas Utility Serviceperson and Restricted Gas Utility licenses exist for narrower roles. Restricted Water and Sewer Service Line holders are expressly excluded from any gas work.

How much does an Arkansas plumbing license cost? For a journeyman, $75 application plus $75 annual license. For a master, $125 application plus $200 annual license. Re-examination is $50. Reinstatement after a lapse is $325 for a master and $150 for a journeyman, plus back fees. Fee waivers are available under Act 725 of 2021 for qualifying low-income applicants. Board fees change — verify with ADH.

What does it cost to bring in a licensed qualifier instead of waiting five years? That depends on the classification you need, the state, the risk profile of the work, and how many licenses you are trying to hold at once — which is why there is no single published number and any site quoting one is guessing. What drives it is scope, exposure, and how long you need the arrangement to run. If you want a real figure for your situation, start with our consultation packages and we will price the actual scope rather than a hypothetical.

Can I use my plumbing license to bid a $40,000 commercial job? No. An ADH plumbing license authorizes plumbing work. Contracting for the job is governed by the Arkansas Contractors Licensing Board, and commercial work requires a commercial contractor license — with a Restricted Commercial license capped at projects under $750,000. Residential contract work of $2,000 or more likewise requires a residential license.

The short version

Arkansas is cleaner than most states once you accept that two agencies are involved. The Department of Health licenses the person who does plumbing and gas work. The Contractors Licensing Board licenses the business that contracts for it, and it will not issue the Mechanical classification unless someone connected to that business holds the trade license.

The failure mode is almost always the same: a good plumber gets the master card, starts bidding work, and finds out at the wrong moment that the trade license was step one of two. If you are at that point — or you need the Mechanical classification before your own five years are up — see how a qualifying agent works, or go straight to hiring one.
