Licensing Requirements
Licensing Requirements
Alabama requires journeyman and master plumber licenses issued by the Alabama Board of Plumbing Examiners. Journeyman: 5 years documented apprenticeship (4500 hours) or equivalent work experience, plus passing the Alabama journeyman exam. Master: minimum 2 years journeyman experience plus passing master exam. Both licenses require CPD (continuing professional development) hours annually—currently 12 hours per year for renewal. Licenses renew every 3 years. No reciprocity with other states; out-of-state plumbers must be licensed or work under a licensed Alabama master plumber.
Permit Requirements
Mobile city and Baldwin County require plumbing permits for most installations. New construction, water heater replacement, major pipe work, and fixture additions all require permits. Permit costs typically range $50-150 depending on project scope. Mobile Building Department processes permits; turnaround is 3-5 business days for standard submissions. Emergency permits available with same-day issuance for documented urgent repairs.
Inspection Schedule
Initial inspection after rough-in (before walls are closed), final inspection after all fixtures are operational. Water heater replacement requires inspection within 48 hours of installation. Mobile Building Department typically schedules inspections within 2-3 business days of request. Failed inspections require corrections and re-inspection; no additional permit fee for re-inspections.
Insurance Minimums
Alabama does not mandate specific insurance minimums by state law, but industry standard is $1 million general liability and $1 million workers' compensation (required if you have employees). Most commercial contracts demand $2 million general liability. Many municipalities including Mobile require proof of liability insurance before issuing permits; carriers typically require minimum $500K-$1M. Bonding not required by state but recommended for commercial work.

How to Get Licensed
Accumulate Work Hours
Document 4500 hours of paid plumbing work under a licensed plumber or master plumber. This typically takes 2-3 years at full-time employment. Keep detailed records: employer name, dates, hours worked, type of work (rough-in, repair, new construction, etc.). Your employer or mentor must verify these hours in writing. Alabama Board of Plumbing Examiners requires certified verification; copies of tax returns and W-2s help substantiate claims.
Complete Application to Alabama Board of Plumbing Examiners
Submit Form PLB-100 (Journeyman Application) to the board. Include: proof of 4500 hours, high school diploma or GED, background check authorization, and application fee ($100-150). Mail to Alabama Board of Plumbing Examiners, Montgomery, AL. Board reviews applications within 2-3 weeks. Incomplete applications get rejected; resubmit corrected version.
Pass the Journeyman Plumber Exam
Schedule exam with PSI (Professional Testing Inc.) or Pearson Vue, Alabama's approved testing vendor. Exam covers: code knowledge (Alabama Plumbing Code and International Plumbing Code), safety, materials, tools, practices, math, and troubleshooting. Test runs 120 questions, 4 hours, $150-200 fee. Passing score is typically 75%. You can retake if you fail; most people pass on first attempt with proper study. Study materials available through NCEES and Alabama board.
Receive Journeyman License and Register with City/County
Upon passing exam, Alabama Board issues your journeyman plumber license (valid 3 years). Register your license with Mobile city and Baldwin County building departments—this allows you to pull permits in your name. Registration typically requires proof of liability insurance and a clean background check. Small registration fee ($25-50). You're now legally authorized to work as a journeyman plumber in Alabama.
Maintain License Through Annual CPD and Triennial Renewal
Complete 12 CPD (continuing professional development) hours annually. Acceptable courses: code updates, safety training, new equipment/materials, business management. Most plumbing suppliers and trade associations offer CPD-accredited classes. Before license expires (every 3 years), submit renewal application with proof of CPD hours, renewal fee (~$150), and clean background verification to Alabama Board. Failure to renew before expiration terminates your license; you must retest to reinstate.
About This Market
Mobile's plumbing market runs steady year-round but heats up May through September when residential and commercial construction peaks and humidity-driven corrosion accelerates repair calls. You've got approximately 1,564 licensed establishments across Alabama, with Mobile's coastal market concentrated on saltwater corrosion issues, older housing stock (pre-1980 galvanized and cast iron), and new commercial development along the waterfront. Median wage sits $27.77/hour statewide, but service plumbers in Mobile's residential market often clear 1.5-2x that through service call markups and emergency premiums. Competition is moderate—enough work to stay busy but plenty of room for quality operators. Costs run higher than inland markets due to material sourcing and specialty corrosion expertise. New construction and commercial fit-outs drive the bigger jobs; residential emergency repairs and water heater replacements are the bread and butter.
To work this market legally, you need an Alabama journeyman or master license—no shortcuts. Get your hours logged, pass the exam, and commit to 12 CPD hours annually or your ticket lapses. Mobile and Baldwin County don't mess around with permits; most jobs require them and inspectors will cite you fast. Budget 3-5 business days for permit processing before you schedule work. Carry $1M liability minimum, preferably $2M if you're bidding commercial. Peak season runs May through September—staff up then, because the work dries to maintenance and emergency calls November through April. Know the local inspectors by name, submit clean permit applications, and you'll get callbacks and referrals. Ignore the licensing or permitting requirements and you're looking at fines, work stoppages, and license suspension.

Frequently Asked Questions
What's the difference between a journeyman and master plumber license in Alabama, and which one do I need?
A journeyman plumber in Alabama has completed 5 years of documented apprenticeship (minimum 4500 hours) or equivalent work experience and passed the state exam. A master plumber has at least 2 years of journeyman experience plus master exam certification. You can work as a journeyman doing installations and repairs under your own license, but cannot legally own a plumbing business or supervise employees without a master's license. If you're solo or employee, journeyman is sufficient. If you're running a shop with employees, you need master. Source: Alabama Board of Plumbing Examiners.
How much does it cost to hire a plumber for emergency service in Mobile, AL?
Emergency service calls (nights, weekends, holidays) typically run $200-$400 just for the service call, plus materials and labor. Standard business hours calls are $150-$250. Labor rates post-diagnosis typically run $75-$150/hour depending on complexity and contractor experience. A simple repair like a leaking valve might cost $250-$400 total; a burst pipe requiring rerouting can hit $1200-$2000+. Always get a written estimate before major work starts. Mobile has no rate-setting authority, so prices vary by contractor reputation and demand.
Do I need a permit for a water heater replacement in Mobile, AL?
Yes. Mobile city and Baldwin County both require plumbing permits for water heater replacement. The permit ensures the installation meets current code and includes inspection within 48 hours of completion. Permit costs $50-$100. If a contractor tells you 'no permit needed,' they're cutting corners—inspectors will cite the property owner, not the contractor, and the work may fail inspection later. Always request the permit be pulled before work starts. Source: Mobile Building Department.
What's the typical turnaround time to get a plumber quote in Mobile?
Expect 24-48 hours for a return call and in-home estimate in Mobile's market. During peak season (May-September), some shops run longer due to volume. Emergency calls get priority—typically 2-4 hours response. Many contractors now offer same-day or next-day scheduling for emergency diagnosis, though repair work may be scheduled 1-3 days out depending on parts availability and crew capacity. Call early in the day for fastest callback; late Friday calls often wait until Monday.
What insurance do I need to carry as a plumber in Alabama?
Alabama state law doesn't mandate specific insurance amounts for plumbers, but industry standard and market requirement is $1 million general liability and $1 million workers' compensation (if you have employees). Most residential customers and all commercial contracts demand proof of $1-2M liability before work begins. Mobile's building department requires proof of liability insurance before issuing permits. Go without and you'll lose jobs and face personal liability if someone gets hurt. Cost runs $30-80/month for solo operators. Source: Industry standards and municipal permit requirements.
