Licensing Requirements
Indiana does not issue a statewide plumber license at the state level for most residential and commercial work — licensing and registration are handled at the local or county level. However, the Indiana Plumbing Commission (under IDOL) requires a Journeyman Plumber Registration and a Master Plumber License for those pulling permits and operating businesses. Master Plumber License: requires proof of 4 years of journeyman-level experience, passing the Indiana Master Plumber exam (administered by PSI Exams), and a $50 application fee. Journeyman Plumber Registration: requires completion of an approved apprenticeship (typically 4-year JATC program) or equivalent documented experience, passing the Indiana Journeyman Plumber exam via PSI, and a $25 fee. Renewals are biennial — licenses expire on the holder's birthday every two years. Continuing education is not currently mandated at the state level but check with the City of Evansville Building Commission for any local CE requirements. Backflow prevention work requires separate ASSE or Indiana-approved certification.
Permit Requirements
All plumbing work in Evansville, IN that involves new installation, extension, alteration, or repair of water supply, drain, waste, or vent systems requires a permit from the City of Evansville Building Commission. Minor repairs like replacing faucets or fixtures typically do not require a permit. Permit fees are calculated based on fixture count and job valuation — typical residential plumbing permits run $75-$200. Applications can be submitted in person at the Evansville Building Commission (1 NW Martin Luther King Jr Blvd) or through their online portal. The permit holder must be a licensed Master Plumber. Work must not be concealed before inspection.
Inspection Schedule
Evansville Building Commission requires a rough-in inspection before walls are closed — this covers all drain, waste, vent, and supply rough-in work. A final inspection is required after all fixtures are installed and the system is operational. For commercial or multi-family work, additional pressure tests and separate inspections for gas line work apply. Inspectors are typically scheduled within 1-3 business days of request. The licensed Master Plumber of record must be available or reachable during inspections.
Insurance Minimums
Indiana does not set a single statewide insurance minimum for plumbers, but the City of Evansville and most general contractors require: General Liability Insurance with a minimum of $500,000 per occurrence and $1,000,000 aggregate — $1,000,000/$2,000,000 is the practical market standard for commercial work. Workers' Compensation Insurance is required by Indiana law for any plumbing business with one or more employees (IC 22-3-2). Tools and equipment coverage is not mandated but strongly recommended given the value of plumbing rigs. Many commercial clients and GCs will require a Certificate of Insurance naming them as additional insured before work begins.

How to Get Licensed
Complete an Approved Apprenticeship or Document Experience
To qualify for a Journeyman Plumber Registration in Indiana, you must complete a 4-year approved apprenticeship program (such as a UA JATC program) or document equivalent hands-on plumbing experience. For Master Plumber licensure, you must additionally show 4 years of post-journeyman field experience. Keep detailed employment records and get verification letters from employers — the Indiana Plumbing Commission will require documentation.
Apply to the Indiana Plumbing Commission
Submit your application to the Indiana Plumbing Commission through the Indiana Department of Labor (IDOL). The Journeyman application fee is $25; the Master Plumber application fee is $50. Include all required documentation of experience and training. Applications can be submitted online via the IDOL licensing portal. Confirm current fee schedules and requirements directly with IDOL, as these can change. Source: Indiana Department of Labor, Indiana Plumbing Commission.
Schedule and Pass the PSI Licensing Exam
Once your application is approved, schedule your exam through PSI Exams (Indiana's approved exam administrator). The Journeyman exam covers the Indiana Plumbing Code, trade math, and installation practices. The Master Plumber exam adds business law, code interpretation, and project management content. You may use a copy of the Indiana Plumbing Code during the exam — know it well. A passing score is required before your license or registration is issued.

Obtain Required Insurance
Before you begin operating, secure General Liability Insurance (minimum $500,000 per occurrence, $1,000,000 aggregate recommended as market standard) and Workers' Compensation Insurance if you have any employees, as required by Indiana law (IC 22-3-2). Have your Certificate of Insurance ready — clients, GCs, and the City of Evansville will request it. Source: Indiana Workers' Compensation Board, City of Evansville Building Commission.
Register with the City of Evansville Building Commission
Present your Indiana Master Plumber License to the City of Evansville Building Commission and register as a licensed contractor in their system. This is required before you can pull permits locally. Bring your state license, insurance certificate, and any required business registration documentation. The Building Commission is located at 1 NW Martin Luther King Jr Blvd, Evansville, IN.

Pull Permits Before Starting Work
For every qualifying plumbing job in Evansville, pull a permit from the Building Commission before work begins. Submit plans or scope of work as required. Do not conceal any rough-in work before the rough-in inspection is completed and signed off. Schedule your final inspection once all fixtures are installed and the system is operational. Failure to permit or pass inspections can result in fines, required demolition of completed work, and license jeopardy. Source: City of Evansville Building Commission.
Renew Your License Biennially
Indiana Plumbing Commission licenses and registrations renew on a biennial cycle tied to the license holder's birthday. Monitor your renewal date and submit renewal applications and fees before expiration to avoid a lapse in licensure. As of current requirements, no state-mandated continuing education hours are required for renewal, but verify with IDOL and check whether the City of Evansville imposes any local CE requirements.

About This Market
Evansville sits on the Ohio River in the southwest corner of Indiana, and that geography drives the plumbing market more than people realize. The city has a mix of aging housing stock — a significant portion built pre-1970 with galvanized or cast iron pipe — alongside active residential development in the outer suburbs and commercial growth near the riverfront. That aging infrastructure keeps drain cleaning, repiping, and sewer lateral work steady year-round. Demand spikes hard in winter when temperatures drop below freezing and calls pour in for burst pipes, and again in spring when homeowners tackle remodels. Competition is moderate — the market supports a range of solo operators, mid-size local shops, and a handful of regional players, but truly qualified licensed Masters are not in surplus. Labor costs in Evansville run below Indianapolis or Chicago norms, which keeps consumer price expectations lower, but material costs have tracked national inflation since 2021 and margins are tighter than they used to be. The approximately 1,955 licensed plumbing establishments counted statewide in Indiana gives you a sense of the field — Evansville's share of that is a competitive but workable slice.
If you're setting up shop here, the first thing you need locked down is your Indiana Master Plumber License — you cannot pull permits in Evansville without it, and working without permits is a fast way to get shut down and fined. Indiana's licensing is handled through the Indiana Plumbing Commission under IDOL, and the exam is no joke — study the Indiana Plumbing Code (based on the IPC with state amendments) front to back. Register with the City of Evansville Building Commission and get familiar with their inspection scheduling process before your first job, because rough-in inspections must happen before you close walls. Winter is your busiest and most profitable season, so make sure your emergency call capacity is staffed up by November — contractors who can't respond to freeze emergencies lose those customers permanently. On the insurance side, carry at least a $1M general liability policy and have your COI ready to produce on demand for any commercial or GC work. Build a relationship with a reliable supply house — either Ferguson or a regional independent — because material availability matters when you're on an emergency call at 10pm.

What permits are required for plumbing work in Evansville, IN?

How many licensed plumbing establishments operate in Indiana?
According to U.S. Census Bureau data, there are approximately 1,955 licensed plumbing establishments operating in Indiana. This includes solo operators, small shops, and larger regional contractors. Evansville and the surrounding Vanderburgh County area represent a meaningful share of that total given the city's size and regional commercial activity.

When is the busiest time of year for plumbers in Evansville?
The peak emergency season runs late November through February, driven by frozen and burst pipes during Ohio River valley cold snaps.

Contractors who do not staff up for winter emergency response consistently lose market share to those who do.
