Missouri requires plumbers to be licensed through the Missouri State Board of Plumbers Examiners. Two primary license types: Journeyman Plumber (requires 4 years documented apprenticeship, 8000+ hours, or equivalent experience, plus passing the state exam covering code, safety, and technical knowledge) and Master Plumber (requires 5+ years documented journeyman experience plus passing advanced master exam). Licenses renew every 2 years; continuing education requirement is 24 hours per renewal period. Exam fees approximately $150-200 per attempt.
Permit Requirements
Independence, MO (Jackson County) requires plumbing permits for most work except minor repairs. Permit applications submitted through Independence Building & Planning Department.

New installations, water heater replacements, drain line work, and rough-in require permits. Permit costs range $35-150 depending on scope. Inspections required at rough-in and final stages.

How to Get Licensed
Confirm apprenticeship eligibility
Contact Missouri State Board of Plumbers Examiners or an approved trade school to confirm you meet apprenticeship prerequisites (typically high school diploma or GED, age 17+, and ability to pass background check). Some employers sponsor apprentices directly; others require you to find your own employer. Verify your path: standard 4-year apprenticeship or equivalent experience petition.
Enroll in registered apprenticeship program
Register with a Missouri-approved apprenticeship program (either through a trade school, union, or registered employer-sponsor). You will log 8000+ hours of paid, supervised plumbing work over 4 years, plus complete classroom instruction (typically 144+ hours per year). Your employer signs off on hours. Keep detailed records of all work performed—inspectors verify this documentation.
Complete required classroom hours
Attend and pass all required classroom instruction through your registered program. Curriculum covers Missouri plumbing code, National Plumbing Code, safety standards, blueprint reading, math, and materials. Classes typically occur 1-2 evenings per week or in intensive blocks. You must maintain passing grades (typically 70%+). Upon completion of all classroom requirements, your program provides proof of completion.
Log 8000+ documented apprenticeship hours
Work full-time under licensed Journeyman or Master supervision. Your employer documents all hours on approved time sheets. Hours must include variety of plumbing tasks (rough-in, fixture installation, repair, maintenance, commercial and residential). Independent verification of hours occurs; falsifying records disqualifies you permanently. Completion typically takes 4 years at full-time pace.
Submit Journeyman license application to Missouri Board
Once apprenticeship is complete, submit formal application to Missouri State Board of Plumbers Examiners with proof of 8000+ hours, classroom completion, and high school diploma/GED. Application fee is approximately $150. The Board reviews for completeness (typically 5-10 business days). You will receive exam authorization once application is approved.
Study for and pass Journeyman Plumber exam
Prepare using Missouri plumbing code, NPC code sections, safety standards, and practice exams (available through trade schools and online providers). Exam covers code compliance, installation standards, troubleshooting, and safety. Pass score is typically 75%+. Schedule exam through Pearson Vue or approved testing center. Exam costs approximately $150-200. You have 3-5 attempts typically before reapplication is required. Allow 2-3 months prep time.
Receive Journeyman Plumber license
Upon passing exam, the Missouri Board issues your Journeyman Plumber license (valid 2 years). License is presented as card and certificate. You can now work independently or supervise apprentices. License renewal occurs every 2 years and requires 24 hours continuing education plus renewal fee (approximately $100-150). Failure to renew by expiration date suspends your license.
Maintain continuing education for renewals
Every 2-year renewal cycle, complete and document 24 hours of continuing education approved by Missouri Board. Courses cover code updates, new materials, safety standards, and business topics. Approved providers include trade schools, industry associations, and online platforms. Keep certificates of completion in your records. Submit proof with renewal application. Failure to complete CE results in license suspension.
About This Market
Independence sits in the Kansas City metro—solid residential market with steady new construction and constant maintenance demand. You're competing against roughly 1,879 licensed plumbing establishments across Missouri, with a decent concentration in the metro corridor. Most work here is residential service calls, water heater replacements, and bathroom remodels tied to home sales and renovations. Costs run middle-of-the-road for the region; material markups are tight because supply chains are efficient and competition is real. Commercial work exists but is fragmented. Median hourly wage for plumbers in Missouri is $36.06/hr ($75k annually), which sets baseline expectations for service pricing. Winter freeze-ups and spring home-improvement season drive volume spikes.
To work this market, you need your Journeyman license minimum—most customers won't touch you without it. Get the apprenticeship hours logged, pass the state exam, and keep your continuing ed current or you lose the ticket. Independence Building & Planning is straightforward but they inspect work, so code compliance isn't optional—it's the baseline. Permits are required for almost everything except minor repairs, so budget for permitting in your quotes and timeline. Insurance proof is expected before permit issuance. Peak season is May-June when every homeowner decides to renovate; have crew depth or you'll be turning down work. Emergency service pricing (nights, weekends, same-day) is where margin lives—customers will pay 2x standard rates for a burst pipe on Saturday. Build relationships with the building department inspectors; they move fast when they know you run clean jobs.
