Alabama Master Plumber License Requirements (2026)

The Alabama Plumbers and Gas Fitters Examining Board (APGFEB) certifies plumbers and gas fitters statewide under Code of Alabama Title 34 Chapter 37. Alabama issues Apprentice, Journeyman, and Master Plumber certifications, plus separate Apprentice, Journeyman, and Master Gas Fitter certifications. The Journeyman Plumber credential requires a four-year approved apprenticeship and a passing score on the Alabama Block Examination. The Master Plumber credential requires the Journeyman credential plus an additional two years of experience and a separate Master-level Block Examination. Master Gas Fitter is a fully separate certification with its own experience and exam requirements.

Governing Authority

Under Code of Alabama Title 34 Chapter 37 (Plumbers and Gas Fitters), Alabama Plumbers and Gas Fitters Examining Board (APGFEB) is the body that issues this license and enforces compliance with it. APGFEB certifies Apprentice, Journeyman, and Master Plumbers as well as Gas Fitters statewide, administers the Block exam, and enforces the Alabama plumbing code.

Phone: (334) 269-9990

Eligibility Requirements

An applicant qualifies only after meeting the age floor of 18 and producing a valid Social Security Number. No Alabama residency requirement; out-of-state applicants may test and license reciprocally where agreements exist.

Good moral character

APGFEB reviews the applicant's background and may deny for felony convictions involving fraud or dishonesty, prior revoked licenses, or repeated code violations.

Background investigation

Mandatory criminal history disclosure on the application; APGFEB may request court records for any disclosed offense.

Experience & Education Matrix

The applicant must document and verify at least four years (8,000 hours) of approved plumbing apprenticeship to qualify for the Journeyman exam, plus two additional years of journey-level experience to qualify for the Master Plumber exam. Keep payroll, tax, project, or supervisor records to support the claim, as the board can request proof for any period within its lookback window.

Accepted proof of experience or eligibility

APGFEB Experience Affidavit signed by each Master Plumber supervisor
Approved plumbing apprenticeship completion certificate
W-2 statements, 1099 records, or pay stubs covering the qualifying period
Copies of prior Apprentice and Journeyman Plumber certifications

Education substitution

Accredited plumbing technology coursework may substitute for a portion of the apprenticeship hours at the board's discretion.

Examination Structure

The licensing examination is delivered by Block Exams (Prometric) under contract to APGFEB. All of the following parts must be cleared prior to issuance:

Alabama Master Plumber Examination — Alabama plumbing code, theory, isometrics, sizing, business and law — 110 questions, 300 minutes, passing score 70%

Examination fee: $130 examination fee paid to Block Exams.

Retake policy: Failed exams may be re-taken after a 30-day wait by paying a new $130 fee. Each application remains valid for one year.

Insurance & Financial Security

The cited state source set does not require a contractor license surety bond for this credential. Contractors should still confirm project-specific bond, permit-bond, or public-works bond requirements before bidding.

General liability

APGFEB does not impose a general liability minimum on the individual credential. Most municipalities require permit-pulling plumbers to carry $300,000 to $1,000,000 in general liability.

Workers' compensation

Workers' compensation insurance is mandatory in Alabama for any business with five or more employees.

Additional financial requirements

APGFEB does not require a net worth financial statement. Plumbing contracting businesses still must register with the Alabama Secretary of State and carry insurance required by local permit offices.

Application and License Fees

Fee	Amount
Application (non-refundable)	$150

Reciprocity and Endorsement

Alabama does not accept the NASCLA Accredited Examination for this classification.

Reciprocal State	Accepted Exam	Conditions
Georgia	Trade exam waived	Bilateral APGFEB–Georgia State Construction Industry Licensing Board reciprocity for active master plumbers.
Tennessee	Trade exam waived	Bilateral APGFEB–Tennessee Board for Licensing Contractors reciprocity for active master plumbers.
Mississippi	Trade exam waived	Bilateral APGFEB–Mississippi State Board of Contractors reciprocity for active master plumbers.
North Carolina	Trade exam waived	Bilateral APGFEB–North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors reciprocity for active master plumbers.

Reciprocal applicants must still apply through APGFEB and pay the application fee. Master Gas Fitter is a separate certification and must be applied for independently.

Common Filing Mistakes

Working from the cited board instructions, here are the snags most likely to trip up a Alabama Plumber filing.

Skipping the apprenticeship step

APGFEB does not recognize informal on-the-job training as a substitute for the approved four-year apprenticeship. Document every hour through the program.

Confusing plumber with gas fitter

Master Plumber and Master Gas Fitter are separate certifications. A Master Plumber may not legally perform gas fitting work without the gas fitter credential.

Studying the wrong code edition

Alabama adopts the plumbing code on a delayed cycle. Confirm the current adopted edition with APGFEB before studying.

Missing continuing education

APGFEB requires CE hours each renewal cycle. Missing CE blocks renewal and may require re-examination after extended lapse.

Letting the credential lapse

A lapsed Master Plumber credential blocks permit-pulling immediately. Annual renewal is mandatory and reinstatement after long lapses can require re-testing.

Frequently Asked Questions

How much experience does Alabama require for a Master Plumber?

Six years total: four years of approved apprenticeship to qualify for the Journeyman exam, plus two additional years of journey-level experience to qualify for the Master Plumber exam.

What is the difference between a Master Plumber and a Master Gas Fitter in Alabama?

They are fully separate certifications. A Master Plumber may not perform gas fitting work without a separate Master Gas Fitter certification, and vice versa. Many plumbers hold both.

Does Alabama have plumber reciprocity with other states?

Yes. APGFEB maintains bilateral master plumber reciprocity agreements with Georgia, Tennessee, Mississippi, and North Carolina. Reciprocal applicants must still apply and pay the Alabama application fee.

Is an apprenticeship the only way to become a Journeyman Plumber in Alabama?

An approved four-year apprenticeship is the standard path. Accredited plumbing technology coursework may substitute for a portion of the hours at the board's discretion, but informal on-the-job training alone is generally not accepted.

How often does the Alabama Master Plumber credential renew?

Every year. Renewal is due by the credential anniversary date and APGFEB may impose late fees for missed renewals.
