Licensing Requirements
Alabama requires plumbers to hold a state-issued license through the Alabama Plumbers and Gas Fitters Examining Board (APGFEB). Three license tiers apply: Apprentice Plumber (registered, no exam, must work under a licensed journeyman or master), Journeyman Plumber (requires proof of 4 years of apprenticeship experience, passing a written exam administered by APGFEB, and a $50 exam fee), and Master Plumber (requires proof of 2 years as a licensed journeyman, passing a separate master-level written exam, $75 exam fee, and submission of a completed application). Master Plumber license is required to pull permits and operate a plumbing contracting business. Licenses renew annually on September 30. Renewal fees are approximately $50 for journeyman and $75 for master. Continuing education is not currently mandated by the board but is strongly recommended. Out-of-state applicants must apply by endorsement and may be required to sit for the Alabama exam if their home state standards are deemed insufficient by the board.
Permit Requirements
In Birmingham, AL, plumbing permits are required for any new installation, replacement, alteration, or repair of a plumbing system beyond minor maintenance. Permits are issued through the Jefferson County Building Department or the City of Birmingham Building, Construction and Demolition Department depending on jurisdiction. A licensed Master Plumber must pull all permits. Permit fees are calculated based on project valuation — typically $50 to $150 for residential work and $150 to $500 or more for commercial jobs. Water heater replacements, sewer line work, repiping, and new construction rough-ins all require permits. Simple fixture swaps (like-for-like toilet or faucet replacement) generally do not require a permit, but confirm with the local authority having jurisdiction (AHJ) before proceeding.
Inspection Schedule
Inspections are coordinated through the City of Birmingham or Jefferson County inspection divisions. For residential plumbing, rough-in inspections are required before walls are closed, and final inspections are required upon project completion. Scheduling is typically done online or by phone 24 to 48 hours in advance. Inspectors generally arrive within a 1 to 2 business day window after scheduling. For slab work, an underground rough-in inspection is required before the pour. Water and sewer tap inspections may also require presence of a utility representative. Failed inspections require re-scheduling and re-inspection fees may apply.
Insurance Minimums
Alabama does not set a single statewide minimum insurance threshold for plumbers at the APGFEB level, but Master Plumbers operating a contracting business are strongly advised — and often contractually required by commercial clients — to carry: General Liability Insurance with a minimum of $300,000 per occurrence and $1,000,000 aggregate (industry standard for residential; commercial projects often require $2,000,000 aggregate), Workers' Compensation Insurance required by Alabama law for any business with 5 or more employees (fewer than 5 is exempt but coverage is still strongly recommended), and a Surety Bond if required by the municipality or contract. Jefferson County and the City of Birmingham may impose additional insurance requirements at the permit application stage — verify with the local building department before starting work.

How to Get Licensed
Register as an Apprentice Plumber
Before any other steps, anyone entering the plumbing trade in Alabama must register as an Apprentice Plumber with the Alabama Plumbers and Gas Fitters Examining Board (APGFEB). This registration requires you to be working under a licensed Journeyman or Master Plumber. Submit a completed registration application and applicable fee to APGFEB. Apprentice registration is not optional — working as an unregistered plumber is a violation of Alabama law.
Accumulate 4 Years of Apprenticeship Experience
Log a minimum of 4 years (typically 8,000 hours) of documented, hands-on plumbing experience under the direct supervision of a licensed Journeyman or Master Plumber. Keep detailed records of your hours and the supervising plumber's license number. APGFEB will require documentation of this experience when you apply for the Journeyman exam. Formal apprenticeship programs through local PHCC chapters or union training programs (UA Local 91 covers the Birmingham area) can help structure and document your training.
Apply for and Pass the Journeyman Plumber Exam
Once you have 4 years of documented experience, submit a Journeyman Plumber application to APGFEB along with your experience documentation and the $50 exam fee. Upon approval, you will be scheduled for the written Journeyman Plumber examination. The exam covers Alabama plumbing codes, the International Plumbing Code (IPC), pipe sizing, fixture installation, drainage, venting, and safety. Prepare thoroughly — this is a technical exam, not a formality. Upon passing, APGFEB will issue your Journeyman Plumber license.
Work 2 Years as a Licensed Journeyman
After receiving your Journeyman license, you must accumulate a minimum of 2 years of experience working as a licensed Journeyman Plumber before you are eligible to sit for the Master Plumber exam. Continue documenting your work experience during this period. Renew your Journeyman license annually by September 30 to keep your credential active during this phase.
Apply for and Pass the Master Plumber Exam
With 2 years of Journeyman experience documented, submit a Master Plumber application to APGFEB along with experience records and the $75 exam fee. The Master Plumber exam is more comprehensive and includes business practices, code administration, advanced system design, and contractor responsibilities in addition to technical content. Upon passing, APGFEB issues your Master Plumber license — the credential required to pull permits, run a plumbing contracting business, and supervise apprentices and journeymen in Alabama.
Obtain Business Licensing and Insurance
With your Master Plumber license in hand, register your plumbing contracting business with the Alabama Secretary of State and obtain a local business license through the City of Birmingham or your operating municipality. Secure a General Liability Insurance policy (minimum $1,000,000 per occurrence recommended; $2,000,000 aggregate for commercial work) and Workers' Compensation Insurance if you employ 5 or more workers. Some commercial clients and municipalities will also require a surety bond. Confirm all local business registration requirements with the City of Birmingham Revenue Division.
Renew License Annually
Both Journeyman and Master Plumber licenses in Alabama renew annually on September 30. Renewal applications and fees must be submitted to APGFEB before the deadline to avoid lapse. Journeyman renewal is approximately $50; Master renewal is approximately $75. A lapsed license means you cannot legally perform or supervise plumbing work until reinstatement is completed. Set a calendar reminder well ahead of the renewal deadline — do not let your license lapse mid-project.
About This Market
Birmingham's plumbing market is active and competitive. With approximately 1,564 licensed plumbing establishments across Alabama according to Census data, and a significant concentration in the Birmingham-Hoover metro, contractors are competing for a mix of residential service calls, renovation work, and a steady pipeline of new construction tied to commercial and industrial growth in the region. Jefferson County's aging housing stock — much of it built before 1980 — generates consistent demand for slab leak repairs, repiping jobs, and sewer line replacements. Costs are driven by material prices (copper and PEX have both fluctuated heavily post-2020), labor availability, and permit and inspection timelines that can add days to a project schedule. Emergency call volume spikes sharply during winter freeze events, when crews are stretched thin and customers are willing to pay premium rates. This is not a soft market — there is real work here — but margins get squeezed fast if you are not pricing labor and materials correctly on the front end.
If you are moving into the Birmingham market or scaling up your plumbing operation, the first thing you need to get squared away is your Master Plumber license through the Alabama Plumbers and Gas Fitters Examining Board. Without that ticket, you cannot pull permits, and without permits, you cannot legally complete the jobs that pay the best. The exam is not a formality — study the Alabama Plumbing Code and International Plumbing Code thoroughly. Plan your permit pulls early, especially on renovation and remodel jobs, because inspection scheduling in Jefferson County can add lead time to your project close-out. Insurance requirements are not always spelled out by the state, but every commercial general contractor in this market is going to ask for a $2 million aggregate liability certificate before they let you on site. Get your coverage right before you bid those jobs. Staff up heading into fall — winter freeze season is your highest-revenue window, and the crews that are positioned and ready are the ones that capture it. Build relationships with local suppliers like Ferguson and Coburn's early; material lead times matter when a customer has no water.

Frequently Asked Questions
How much does it cost to hire a plumber in Birmingham, AL?
In Birmingham, expect to pay $150 to $400 for a drain cleaning, $900 to $1,800 for a water heater replacement, and $4,500 to $12,000 for whole-house repiping. Emergency and after-hours calls typically carry a service fee surcharge of $75 to $150 on top of standard rates. These figures are market estimates based on regional contractor pricing data — always get at least three written quotes before committing to a project.
Does a plumber in Alabama need a state license?
Yes. Alabama requires plumbers to be licensed through the Alabama Plumbers and Gas Fitters Examining Board (APGFEB). There are three tiers: Apprentice (registered, no exam), Journeyman (exam required after 4 years of documented apprenticeship), and Master Plumber (exam required after 2 years as a licensed journeyman). Only a licensed Master Plumber can pull permits and legally operate a plumbing contracting business in Alabama. Verify current requirements directly with APGFEB at apgfeb.alabama.gov.
Do I need a permit for plumbing work in Birmingham, AL?
Yes, for most plumbing work beyond minor maintenance. This includes water heater replacements, new rough-in plumbing, repiping, and sewer line work. Permits are issued through the City of Birmingham Building Department or Jefferson County Building Department depending on your location. A licensed Master Plumber must pull the permit. Fees typically run $50 to $150 for residential work. Skipping permits is not worth the risk — unpermitted plumbing can create insurance, liability, and resale problems down the line.
How many licensed plumbing businesses operate in Alabama?
According to U.S. Census Bureau data, there are approximately 1,564 licensed plumbing establishments operating in Alabama. A significant portion of these are concentrated in the Birmingham-Hoover metropolitan area, reflecting the region's population density and construction activity. This translates to a competitive but active market with consistent demand across residential, commercial, and industrial segments.
When is the busiest time of year for plumbers in Birmingham?
Winter is the peak emergency season. Birmingham averages occasional hard freezes — temperatures dropping into the low 20s or teens — which trigger burst pipe calls at high volume. December through February is your highest-demand window for emergency service work. Spring (March through May) drives the remodeling and new construction surge as building permits increase and homeowners launch renovation projects. Contractors who staff up and stock materials ahead of these windows consistently outperform those who react to demand after it hits.
