Plumbing License Law and Board Rules

Learning Objectives

Upon mastering this chapter, you will be able to:

4.Identify the statutory authority of the Texas State Board of Plumbing Examiners (TSBPE) and the scope of its rulemaking power.
5.Distinguish between the classifications of plumbing licenses and the specific scope of work each authorizes.
6.Apply the continuing education (CE) requirements, renewal cycles, and reinstatement procedures.
7.Recognize prohibited acts, unlicensed practice, and the disciplinary penalty matrix.
8.Understand the responsibilities of a Master Plumber as the person in responsible charge of plumbing work.
9.Navigate the Texas Occupations Code, Chapter 1301, and Title 22, Texas Administrative Code (TAC), Chapter 365.

1.1 Statutory Framework and Regulatory Authority

The Texas plumbing profession is governed by the Texas Occupations Code (TOC), Chapter 1301 (Plumbers), and the implementing rules found in Title 22, Texas Administrative Code (TAC), Part 4, Chapter 365 (State Board of Plumbing Examiners). The TSBPE operates under the Texas Department of Licensing and Regulation (TDLR) for administrative support, but it retains independent rulemaking authority over licensing standards.

The Board’s primary statutory duties include: examining and licensing plumbers, adopting a plumbing code (the Board adopts the 2018 editions of the IPC and IFGC, or the UPC, depending on local jurisdiction adoption), enforcing continuing education standards, and investigating complaints. For the exam, you must know that the Board does not write the plumbing code — it adopts codes by reference. Local jurisdictions (cities, counties) may amend the code, but amendments cannot conflict with state minimum standards.

Key statutory terms:

"Plumbing" — the installation, repair, alteration, or maintenance of potable water supply, drainage, venting, and gas piping systems, including fixtures and appurtenances.
"Plumbing work" — includes the connection of appliances to the water supply or drainage system, but excludes the appliance itself unless it is a water heater or similar fixture requiring a permit.
"Person in responsible charge" — the Master Plumber who supervises plumbing work and is accountable for code compliance and permit requirements.

1.2 License Classifications and Scope of Work

Texas License Classifications Scope Ladder Texas License Classifications Scope Ladder TX-MST Ch. 7 — Plumbing License Law & Board Rules · IPC/UPC 2018 · OSHA 1926 · TAS · NFPA 54 RUNG 1 Apprentice Plumber Registered · 1:1 supervision RUNG 2 Tradesman Plumber Limited scope · 2 yrs licensed RUNG 3 Journeyman Plumber 4,000 hrs + exam · 4 yrs RUNG 4 Master Plumber 12,000 hrs + exam · 8 yrs RUNG 5 Responsible Master Plumber Designated for company Tradesman Limited Scope (Rung 2) One- & two-family dwellings only Under direct supervision of a Master Plumber No commercial · No medical gas · No heaters > 75,000 Btu/hr 75K Plumbing Contractor License — Company Panel Company Entity Designated RMP Must be an officer, owner, or employee of the company Cannot serve more than one company at a time without board approval RMP Closed-book · Memorized recall IPC/UPC 2018 · OSHA 1926 · TAS · NFPA 54 MasterPlumberPractice

The Board issues several license types. For the Master Plumber exam, you must know the precise boundaries of each classification because a Master may be asked to supervise or verify the work of others.

License TypeAuthorized Scope
**Apprentice Plumber**Works under the direct supervision of a Journeyman or Master. No independent work. Must be registered.
**Tradesman Plumber (Limited)**May perform plumbing work in one- and two-family dwellings only, under the supervision of a Master. Cannot work on commercial systems, water heaters over 75,000 BTU/hr, or medical gas.
**Journeyman Plumber**May perform all plumbing work under the supervision of a Master Plumber. Cannot pull permits or act as the responsible person.
**Master Plumber**May perform all plumbing work, supervise Journeymen and Apprentices, pull permits, and act as the person in responsible charge.
**Responsible Master Plumber (RMP)**A Master who has designated themselves (via Board form) as the responsible licensed person for a specific plumbing company. The RMP is the individual the Board holds accountable for all work performed under that company’s license.

Critical distinction: A Master Plumber license is personal. A company (corporation, LLC, partnership) must hold a Plumbing Contractor License and designate an RMP. The RMP must be a Master Plumber who is an officer, owner, or employee of the company. The RMP cannot serve in that capacity for more than one company at a time, unless the companies are under common ownership and the Board approves.


1.3 The Master Plumber as Person in Responsible Charge

Responsible Charge Supervision Standard — Master Plumber (TX TOC 1301.351) Responsible Charge Supervision Standard TX TOC 1301.351 · Chapter 7 — Plumbing License Law & Board Rules · IPC/UPC 2018 · OSHA 1926 · NFPA 54 · TAS MASTER PLUMBER PHYSICALLY PRESENT or available ≤ 30 min VERIFY LICENSES every worker on site CONFIRM PERMITS before work begins ANSWER FOR VIOLATIONS by supervised journeymen WRITTEN BOARD NOTICE within 30 days · employment/company change UNSUPERVISED WORK = unlicensed practice ! JOURNEYMEN direct supervision required TOC 1301.351 · Ch. 7 MasterPlumberPractice Closed-book · Memorized recall ● Copper flow = supervision duty path

The single most important legal concept for the Master Plumber is responsible charge. Under TOC §1301.351 and 22 TAC §365.20, the Master Plumber must:

Directly supervise the work, meaning the Master must be physically present at the job site or available within a reasonable time and distance (the rule presumes availability within 30 minutes for most work; for complex or high-risk work, physical presence is required).
Ensure that all workers on the project hold valid, appropriate licenses.
Verify that permits are obtained before work begins.
Ensure the work complies with the adopted code (IPC/UPC) and all local amendments.
Be accountable for code violations, even if the actual work was performed by a Journeyman.

Exam trap: The Board does not require the Master to be on site 100% of the time, but the Master must be "readily available." If a Journeyman performs work without any Master supervision, the Journeyman is practicing without a license, and the Master (if named as RMP) faces disciplinary action.

Field practice: As a Master, you should conduct periodic site inspections, maintain a written supervision log, and ensure that permit cards are posted. If you are the RMP for a company, you must notify the Board in writing within 30 days of any change in your employment status or company affiliation.


1.4 Continuing Education and License Renewal

Continuing Education Hour Budget by License Continuing Education Hour Budget by License Texas State Board of Plumbing Examiners — Biennial Renewal · Closed-Book Memorized Recall Master Plumber Journeyman Tradesman 10 hrs Technical Topics IPC/UPC · OSHA 1926 TAS · NFPA 54 2 hrs Code Changes 4 hrs TX License Law & Board Rules TOTAL: 16 HOURS 6 hrs Technical Topics IPC/UPC · OSHA 1926 2 hrs Code Changes 4 hrs TX License Law & Board Rules TOTAL: 12 HOURS 2 hrs Technical Topics 2 hrs Code Changes 4 hrs TX License Law & Board Rules TOTAL: 8 HOURS Biennial Renewal Birth-month cycle • Renew by license holder's birth month every 2 years ! No Carryover Excess hours lost • Cannot bank extra hours toward next cycle Lapse After 12 Months Reinstatement required • License inactive after 12 months • May require exam retake MasterPlumberPractice IPC 2018 UPC 2018 OSHA 1926 TAS NFPA 54 ◆ CORE REQUIREMENT — ALL LICENSE LEVELS ◆

All plumbing licenses expire on the last day of the licensee’s birth month, every two years (biennial renewal). The renewal cycle is staggered by birth month, not by calendar year.

Continuing Education (CE) Requirements:

Master Plumber: 16 hours of CE per renewal cycle, of which at least 4 hours must be on the Texas Plumbing License Law and Board Rules (this chapter’s content), and at least 2 hours on code changes (IPC/UPC updates). The remaining 10 hours may be on technical plumbing topics, safety, or business management.
Journeyman Plumber: 12 hours per cycle, with the same 4-hour law/rules requirement and 2-hour code update requirement.
Tradesman and Apprentice: 8 hours per cycle (Tradesman); Apprentices have no CE requirement but must renew registration.

Key rules:

CE must be from a Board-approved provider. The Board publishes a list of approved providers on its website.
You cannot carry over excess CE hours to the next cycle.
If you renew late, you may be subject to a late fee. If you fail to renew within 12 months of expiration, your license is lapsed and you must apply for reinstatement, which may require retaking the exam.
The Board may grant a CE waiver for active military duty or medical hardship, but you must apply in writing before the expiration date.

Exam trap: The 4-hour law/rules CE requirement applies to every renewal cycle, including the first renewal after initial licensure. Many candidates assume that because they passed the law exam, they are exempt — they are not.


1.5 Prohibited Acts and Disciplinary Actions

The Board has the authority to discipline any licensee for violations of the statute or rules. The most common violations tested on the exam include:

52.Unlicensed practice — performing plumbing work without a license, or allowing an unlicensed person to perform work under your supervision.
53.Permit fraud — pulling a permit for work that you did not perform or did not supervise.
54.False statement on application — including failing to disclose prior criminal history or disciplinary actions in other states.
55.Gross negligence or incompetence — performing work that endangers public health or safety (e.g., cross-connection between potable and non-potable water).
56.Failure to comply with a Board order — including failure to pay an administrative penalty.
57.Aiding and abetting — allowing your license number to be used by an unlicensed person, or "lending" your license to a company that has not designated you as RMP.

Disciplinary Penalty Matrix (22 TAC §365.64):

Administrative penalty: Up to $5,000 per violation, per day for continuing violations.
License suspension: For a fixed period (e.g., 30–180 days) or indefinite until conditions are met.
License revocation: Permanent loss of license. You may reapply after 5 years, but the Board has discretion.
Probation: The Board may place you on probation with conditions (e.g., random inspections, mandatory CE beyond the standard requirement).

Important due process point: The Board must provide written notice of the alleged violation and an opportunity for a hearing under the Texas Administrative Procedure Act (APA). You have the right to legal counsel and to present evidence. A default judgment occurs if you fail to respond within the specified time (typically 20 days from notice).


1.6 Insurance, Bonding, and Financial Responsibility

Texas law requires all plumbing contractors to maintain:

Workers' compensation insurance — if the contractor has employees (Texas does not mandate coverage for sole proprietors with no employees, but the Board requires proof of coverage or a signed waiver).
General liability insurance — minimum of $300,000 per occurrence and $500,000 aggregate (verify current limits; the Board may adjust by rule).
Surety bond — the Board requires a $10,000 bond for the Plumbing Contractor License. The bond is not for the benefit of the contractor; it protects the public and the Board against violations. Claims against the bond can be made by the Board or by an injured party (e.g., a homeowner who suffered damage due to defective work).

Exam trap: The bond is not a performance bond. It does not guarantee completion of a project. It is a license bond that covers penalties and damages arising from code violations or unlicensed acts.


1.7 Permits, Inspections, and Local Jurisdiction

While the Board regulates licensure, permits and inspections are enforced by local jurisdictions (municipalities, counties). However, the Master Plumber is responsible for knowing the local requirements where the work is performed.

General permit rules:

A permit is required for any plumbing work, including repairs, alterations, and new installations.
Emergency work may begin without a permit, but the permit must be obtained within one business day (or as specified by local ordinance).
The permit holder is the Master Plumber or the company (with RMP named). The permit must be posted at the job site.
Inspections are required at rough-in and final stages. The Master Plumber must be available for the inspection or designate a Journeyman who was directly involved in the work.

Code adoption: The Board adopts the 2018 IPC and IFGC (or UPC) as the minimum standard. Local jurisdictions may adopt more stringent requirements, but they cannot weaken the state minimum. For the exam, you are tested on the state minimum — the 2018 code editions.


1.8 OSHA and Workplace Safety (29 CFR 1926)

Although OSHA is a federal agency, the Board incorporates OSHA standards into its rules for disciplinary purposes. A Master Plumber who fails to maintain a safe job site can be cited by OSHA and disciplined by the Board.

Key OSHA requirements for plumbers:

Trenching and excavation (1926.651–652): Any trench deeper than 5 feet must have a protective system (shoring, sloping, or shielding). A competent person must inspect the trench daily and after any rain event.
Confined spaces (1926.1200 series): A permit-required confined space (e.g., a sewer manhole) requires atmospheric testing, ventilation, and an attendant.
Personal protective equipment (PPE): Hard hats, safety glasses, gloves, and hearing protection as required by the task.
Ladder safety (1926.1053): Ladders must extend 3 feet above the landing surface and be secured.
Hot work (1926.352): When soldering or brazing, a fire extinguisher must be within 30 feet.

Exam trap: OSHA violations are not "plumbing code" violations, but the Board can discipline a Master for "gross negligence" if an OSHA violation leads to a serious injury or death on a plumbing job site.


1.9 Texas Accessibility Standards (TAS)

The TAS is based on the 2012 ADA Standards and is enforced by the Texas Department of Licensing and Regulation (TDLR). For plumbers, the key provisions are in Chapters 4 and 6 of TAS:

Toilet rooms: Clear floor space of 30" × 48" at fixtures; grab bars at water closets (42" long, mounted 33–36" above floor); toilet centerline 16–18" from side wall.
Lavatories: Knee clearance of 27" high, 30" wide, and 11–25" deep; insulated pipes to prevent burns.
Drinking fountains: Spout height 36–43" for wheelchair access; a parallel approach with knee clearance.
Showers: Transfer-type showers require a 36" × 36" minimum; grab bars on the back wall and side wall.

Master Plumber responsibility: You must verify that the rough-in dimensions for accessible fixtures are correct before the concrete is poured or the wall is closed. A common error is installing the water closet flange at 16" from the finished wall, but failing to account for tile thickness, resulting in a 15" centerline — a TAS violation.

1.11 Common Exam Traps and Field Points

Trap 1: "Direct supervision" vs. "responsible charge." A Journeyman works under the "direct supervision" of a Master, meaning the Master must be on site or immediately available. An Apprentice works under "direct supervision" of a Journeyman or Master, meaning the supervisor must be on the same job site and within sight or sound.

Trap 2: License expiration date. Licenses expire on the last day of your birth month, not on December 31. A Master born in March renews in March every two years.

Trap 3: The RMP cannot be "on paper only." The Board presumes that the RMP is actively engaged in the business. If the RMP works full-time for another employer and never visits the company’s job sites, the Board will consider this a sham arrangement.

Field Point: As the Master, always carry your license card. If an inspector or Board agent requests identification, you must produce it. Failure to do so is a Class C misdemeanor.

Field Point: When you sign a permit application, you are certifying that you will supervise the work. If a Journeyman performs the work and you never show up, you are liable for any defect — even if the Journeyman is highly competent.

Field Point: Keep a CE log. The Board audits a percentage of licensees each cycle. If you cannot produce certificates of completion, you will be subject to disciplinary action, even if you actually attended the courses.


1.12 Summary of Master-Level Responsibilities

The Master Plumber license is not merely a higher grade of Journeyman — it is a business and legal designation. The Master is the public’s first line of defense against unsafe plumbing. The Board expects the Master to:

Know the law and rules, not just the plumbing code.
Maintain current CE and insurance.
Supervise all work, including work performed by other licensed tradesmen.
Ensure permits are pulled and inspections are scheduled.
Act ethically — never lend your license, never sign a false permit, and never allow unlicensed work.

On the exam, questions in this chapter will test your ability to apply these rules to real-world scenarios. When in doubt, choose the answer that reflects the highest level of supervision and the strictest interpretation of the law — the Board’s enforcement philosophy favors public protection over convenience for the licensee.
