How to Get Licensed
Step 1: Verify Work Experience and Document Hours
For Master Plumber (M-1): Accumulate and document 5 years of full-time plumbing experience under a licensed plumber or through an apprenticeship program. For Journeyman (J-1): Complete 4 years of apprenticeship or equivalent documented experience. Keep detailed records of employers, dates, hours, and job types. Louisiana State Licensing Board requires signed verification from supervisors. Work experience cannot include time as a laborer or helper—must be active plumbing work (installation, repair, troubleshooting, code compliance).
Step 2: Enroll in Approved Continuing Education (Pre-Exam)
Complete 8 hours of approved continuing education in Louisiana Plumbing Code and National Standard Plumbing Code before exam eligibility. Approved courses are offered through vocational schools, technical colleges, and contractor associations. Obtain proof of completion (certificate). This requirement is waived for first-time applicants if you've completed an accredited apprenticeship program that included code instruction. Proof must be submitted with application.
Step 3: Submit Application and Financial Documentation
File application with Louisiana State Licensing Board for Contractors (SLBC). Provide: documented work history (5 years for M-1, 4 years for J-1), continuing education proof, proof of financial responsibility ($10,000 for M-1, $5,000 for J-1—can be savings, bond, or letter of credit), government-issued ID, and application fee ($150–$200). Application processing takes 2–4 weeks. Incomplete applications are rejected and must be resubmitted.
Step 4: Pass the State Licensing Exam
Schedule exam through PSI (Pearson Vue) or ProctorU. Exam covers Louisiana Plumbing Code, National Standard Plumbing Code, safety regulations, business practices, and math/calculations. M-1 exam is 100 questions, 4 hours. J-1 exam is 80 questions, 3.5 hours. Passing score is 70%. Study materials are available through SLBC website and vocational schools. Exam fee is approximately $150–$200. You can retake the exam if you fail (typically 30-day waiting period). Schedule exam during Step 3 while application is being processed.
Step 5: Receive License and Register with New Orleans
Upon passing exam and application approval, SLBC issues your Master or Journeyman Plumber license (valid 2 years). Register with New Orleans Building Department for local contractor status (separate requirement). Obtain your City Contractor Registration number (required on all permits and job sites). File proof of insurance with the city. Your license and registration are now active; you can legally bid and perform plumbing work in Louisiana. Display license at primary business location. Renew every 2 years with 8 hours continuing education and $150 renewal fee.
About This Market
New Orleans plumbing work is steady and relentless. You've got year-round demand from the residential base and hospitality sector, but May through September is where the money is—hurricane prep, water damage repairs, and seasonal renovations. Competition is moderate to heavy; Census data shows roughly 1,529 licensed establishments statewide, with New Orleans being the largest concentration. Costs run higher than national average because of the water table, subsidence, clay soil conditions, and the fact that most homes sit below sea level—copper and cast iron are eating corrosion issues you can't avoid. New construction rough-ins and renovation work dominate the market, but emergency calls and service work keep cash flow steady year-round. The median hourly rate sits around $30.11/hr, but experienced contractors with crews bill at $150–$400/hr labor depending on job complexity and emergency status.

Frequently Asked Questions
What is the difference between a Master Plumber (M-1) and Journeyman Plumber (J-1) license in Louisiana?
Master Plumber (M-1) requires 5 years documented experience, passage of the state exam, and $10,000 financial responsibility. You can work independently, bid jobs in your name, and supervise apprentices. Journeyman (J-1) requires 4 years apprenticeship or equivalent experience, the same state exam, and $5,000 financial responsibility. A J-1 can perform plumbing work independently but cannot sign off on permits or supervise others on commercial jobs—must work under an M-1. Both licenses renew every 2 years with 8 hours of continuing education. Source: Louisiana State Licensing Board for Contractors.
How much does a typical plumbing service call cost in New Orleans?
A standard service call (diagnostic visit) runs $150–$300 after hours, $100–$150 during business hours. Drain cleaning (residential single fixture) is $200–$500. Emergency calls outside normal business hours (nights, weekends, holidays) add 50–100% markup. Water heater replacement, the most common major service, ranges $1,200–$2,500 installed. Costs are higher than national averages due to New Orleans' subsidence, clay soil, and corrosion issues. Labor rates average $30.11/hr per BLS data, but experienced licensed plumbers bill $75–$150/hr plus materials and service fees.
Do I need a permit for plumbing work in New Orleans?
Yes. New Orleans Building Department requires permits for all new installations, repairs, or replacements of water supply lines, drain lines, fixtures, or appliances. Work under $1,000 may qualify for expedited processing but still requires a permit. Rough-in and final inspections are mandatory and must be scheduled within 24 hours of work completion. Emergency repairs have 24-hour permit windows. Backflow prevention devices require separate certification. Failure to pull permits results in citations, permit revocation, and potential license suspension. Source: New Orleans Building Department, City Code Chapter 26.
What insurance do I need to work as a plumber in New Orleans?
Minimum General Liability insurance of $300,000 per occurrence and $1,000,000 aggregate is required for city work and bonding. Workers' Compensation is mandatory if you have any employees (statutory limits per Louisiana Workers' Compensation Act). Pollution/Environmental Liability of $500,000 minimum is strongly recommended due to groundwater and soil contamination risks from subsidence and aging infrastructure. All policies must be active, current, and provided at job start. Proof of insurance must be presented to the Building Department before permit issuance.

When is the busiest plumbing season in New Orleans, and should I hire extra crews?
Peak season runs May through September. Demand spikes due to hurricane preparation (backflow devices, sump pump upgrades), summer renovation projects, and water intrusion issues from heavy rain and the wet season. June–August are typically the heaviest months. Plan to hire or contract additional crews by April; experienced plumbers book out fast during peak season. Response times compress from 24–48 hours to 4–24 hours. Average hourly wages ($30.11/hr per BLS) increase 10–20% during peak season due to demand and overtime. Have at least one on-call team available for emergency water damage and storm-related work.
