How to Get Licensed
Register as an Apprentice
Locate a licensed plumber or plumbing contractor willing to sponsor your apprenticeship. Register with Tennessee Board for Licensing Contractors via their apprenticeship program. You must complete 4-year apprenticeship with minimum 144 classroom hours annually plus documented on-the-job training hours. Classroom training available through community colleges (Chattanooga State, Cleveland State) or trade unions.
Complete Apprenticeship and Training Hours
Work under your sponsor contractor for 4 years, logging all hours and training completion. Maintain records of on-site work, systems studied, and code compliance. Attend and pass all annual classroom instruction. Tennessee requires documentation of at least 2,000 hours of supervised field work and related classroom instruction per year. Your sponsor contractor is responsible for submitting completion records to the Board.
Apply for Journeyman Plumber License
Once apprenticeship complete (4 years or equivalent), submit application to Tennessee Board for Licensing Contractors with proof of hours, training completion, and sponsor sign-off. Application fee approximately $150-$200. Include verification from your sponsor contractor and classroom institution. Processing typically 2-4 weeks.
Schedule and Pass Journeyman Exam
After application approval, register for Journeyman Plumber exam through Pearson VUE testing centers (available in Chattanooga and surrounding areas). Exam covers Tennessee plumbing code, National Plumbing Code, safety, math, and practical scenarios. Study materials provided by Board. Most candidates schedule exam 2-4 weeks after approval. Pass score required; failure allows retake after 30 days.

About This Market
Chattanooga's plumbing market is steady and competitive. You've got established crews, franchise operations, and independent contractors all hunting the same residential and light commercial work. Demand is solid—aging housing stock, new construction in Northgate and Southside, plus steady commercial activity downtown and along the corridor. Winter drives emergency calls (frozen pipes, water damage), spring brings renovations and water heater replacements. Costs run higher than rural East Tennessee but lower than Nashville or Atlanta. Service call rates $150-$300, full jobs scale with material and scope. Competition keeps margins real—you need efficiency, customer retention, and reputation to stand out.
To work Chattanooga, you need a valid Tennessee plumbing license—journeyman minimum for most work, master for owning and contracting your own jobs. Get permits filed before you swing a wrench on anything structural; the building department checks rough-in and final, and they'll cite you. Inspections move slow in spring (peak season), so schedule early. Winter and summer are your secondary seasons—use that time for preventative maintenance marketing and commercial bids. Insurance isn't state-mandated but it's non-negotiable for residential and essential for commercial. Know your local inspectors and building officials; relationships matter. EPB (water utility) and Tennessee Gas move slow on approvals, so factor that into timelines. Stick to code, pull permits, and you'll build steady work.
