How to Start a Plumbing Business in Georgia

Georgia licenses individual plumbers — journeymen and masters — through the Georgia State Division of Master and Journeyman Plumbers, which operates under the Secretary of State. That’s different from electrical work in this state, where only contractor businesses get licensed rather than individual tradespeople. For plumbers, the license follows you personally, and the license level you hold determines exactly what you can do and whether you can own the business.

If you’re a journeyman thinking about going out on your own, here’s the core constraint: you need a master plumber license to own or operate a plumbing business in Georgia. Journeymen can work independently in the field, but legally they must work under a master plumber’s business. That means the path to ownership runs through the master exam, not around it.

This guide covers how to get there — the license ladder, the exam details, the business formation steps, and what it costs to get started.

Georgia Plumbing License Types

There are two license levels for individual plumbers in Georgia: journeyman and master. Master splits into two classes. Understanding the difference matters before you invest years working toward one or the other.

Journeyman Plumber

A journeyman license requires three years of apprentice or helper experience working under a licensed plumbing contractor. That’s hands-on field time — not classroom hours, not theory. You’re learning the trade while employed, and after three years you’re eligible to sit for the journeyman exam.

A journeyman can perform plumbing work but can’t run a business. You can take jobs, you can work in the field, but your work has to fall under a master plumber’s license. Think of it as the working license, not the business license.

Master Plumber Class I

This is where it gets specific. A Class I master license is restricted to:

Single-family residential buildings
One- and two-family buildings that are one level
Commercial structures under 10,000 square feet

Class I is designed for plumbers who focus on residential and small commercial work. If your plan is to serve homeowners, handle remodels and new builds on single-family homes, and take on small retail or office jobs, Class I covers everything you’ll need. Most solo plumbing businesses in Georgia operate comfortably within these limits.

Master Plumber Class II

Class II is unrestricted. You can take on any plumbing work — large commercial buildings, multi-story structures, industrial projects, anything. If you’re planning to bid on hospital renovations, apartment complexes, or large commercial construction, Class II is what you need.

The license you pursue affects your business ceiling. A lot of plumbers start with Class I and upgrade later. Others go straight for Class II if they know their market from the start.

Experience Requirements for Master

To qualify for a master license at either class, you need a minimum of five years total plumbing experience. At least two of those years must be as a licensed journeyman in Georgia. The sequence matters: you can’t skip journeyman and test directly for master.

So the minimum timeline looks like this: three years as an apprentice/helper → pass journeyman exam → two years working as a licensed journeyman → pass master exam. Five years total, at minimum, before you can own a plumbing business in this state.

All licenses — journeyman and master — are issued by the Georgia State Division of Master and Journeyman Plumbers under the Secretary of State.

Exam and Application Details

Once you’ve met the experience requirements, the application and exam process is straightforward. Exams are administered by PSI, a third-party testing company that handles licensing exams for many Georgia professional boards.

Journeyman:

Application fee: $30
Exam fee: $233
Passing score: 70%

Master (Class I or Class II):

Application fee: $30
Exam fee: $267
Passing score: 70%

The Class I and Class II master exams are different tests. The content scope of Class II is broader, reflecting the unrestricted work it authorizes.

Education Substitutions

If you have formal training, Georgia allows it to count toward the experience requirement:

An associate degree or Career Tech diploma with 1,000+ classroom hours substitutes for two years of the experience requirement
A program with 500+ hours substitutes for one year

This can meaningfully accelerate your timeline. If you went through a technical college plumbing program before or while working in the field, check your transcripts — you may qualify for the master exam sooner than you think.

License Renewal and Continuing Education

Georgia plumbing licenses renew every two years. The renewal fee is $75. You’re also required to complete four hours of continuing education per year — that’s eight hours per two-year renewal cycle. The CE requirement keeps you current on code changes and keeps your license active.

Don’t let renewal slip. A lapsed license means you can’t legally operate, and reactivating a lapsed license involves more paperwork and fees than just renewing on time.

Starting Your Plumbing Business

You’ve passed the master exam. Now you need a business entity, a tax registration, and a local license before you take your first job as an owner.

Form an LLC

An LLC is the standard choice for a solo plumbing business. It separates your personal assets from business liability — important in a trade where a faulty installation can cause serious property damage or worse.

File online at ecorp.sos.ga.gov. The filing fee is $100. Annual registration runs $60 per year, due between January 1 and April 1 each year. Miss the April 1 deadline and you owe a $25 late penalty.

You can file online in a few minutes. Name your LLC (it needs to be distinguishable from existing Georgia business names), appoint a registered agent with a Georgia street address, and submit. No attorney required for this step — the state’s online system is clean and straightforward.

Get an EIN

An EIN (Employer Identification Number) is your federal tax ID. You need it to open a business bank account, hire employees, and register for state taxes. Get one free at irs.gov/ein. Takes about five minutes online.

Register with Georgia Tax Center

Sales tax — Georgia’s base rate is 4%, with local rates on top. Total rates typically run 7–9% depending on your county. Whether plumbing labor is taxable depends on job type, so check the Department of Revenue guidance for service businesses specifically.
Employer withholding — if you hire employees

Georgia’s state income tax is a flat 5.19% for 2025.

Get Your Local Occupation Tax Certificate

Georgia doesn’t have a statewide general business license. Licensing happens at the city or county level. What you need is called an occupation tax certificate — commonly called a business license — and every jurisdiction handles this a little differently.

Two Georgia-specific requirements come up on every occupation tax certificate application:

E-Verify Affidavit: Required under O.C.G.A. § 36-60-6. If you have 11 or more employees, you must register for E-Verify and provide your user number. Fewer than 11 employees? You file an exemption affidavit instead. Either way, something needs to be filed — there’s no skipping this.

SAVE Affidavit: Required under O.C.G.A. § 50-36-1. You must verify lawful presence in the United States using a Secure and Verifiable Document. This requires notarization. Bring your passport or other qualifying document to a notary before you submit the application.

Check with your city or county directly for the specific form, fee, and any local plumbing contractor registration requirements that may stack on top of your state license.

Insurance Requirements

Plumbing businesses carry real liability. A pipe installed wrong can flood a house. A water heater installation done incorrectly can cause carbon monoxide issues or fire. Insurance isn’t optional — and neither is thinking carefully about what coverage you actually need.

General Liability This is your baseline coverage. It covers third-party property damage and bodily injury claims. For a plumbing business, $500,000 to $1,000,000 per occurrence is the standard recommendation. Some commercial clients and general contractors will require you to show a certificate of insurance before they’ll let you on the job.

Workers’ Compensation Required by Georgia law once you have three or more employees. That count includes officers and part-time workers — not just full-time field staff. The Georgia State Board of Workers’ Compensation oversees compliance. If you’re a solo operator with no employees, you’re not required to carry it, but you should understand that you’re not covered for your own injuries either.

Commercial Auto Your personal auto policy won’t cover a work van used for business. Commercial auto insurance covers your vehicles, the tools and materials in them, and liability if you’re in an accident on the way to a job.

Tools and Equipment Coverage Plumbing tools are expensive. A well-equipped service plumber carries thousands of dollars in pipe wrenches, drain snakes, inspection cameras, press tools, and specialized equipment. Tools and equipment coverage (sometimes called inland marine insurance) covers theft, damage, and loss.

Professional Liability Also called errors and omissions insurance. This covers claims arising from faulty workmanship — installations that fail, designs that cause problems, advice that goes wrong. General liability covers third-party injury and property damage from your operations; professional liability covers claims that your work itself was defective. For plumbers doing design-build work or complex installations, this matters.

What to Budget Insurance for a solo master plumber running a small plumbing business in Georgia typically runs $4,000 to $12,000 per year. The range is wide because it depends on your revenue, how many employees you have, your vehicle count, and your claims history. Get quotes from at least three insurers. Specialty trade contractor insurers often beat general business insurers on price for this coverage profile.

Startup Costs at a Glance

Starting a plumbing business isn’t cheap. Here’s a realistic breakdown for a solo master plumber launching in Georgia:

Item	Cost
LLC filing	$100 (one-time)
Annual registration	$60/year
Master plumber application	$30
Master plumber exam	$267
License renewal	$75 every 2 years
Occupation tax certificate	Varies by city/county
Insurance (general liability, commercial auto, tools)	$4,000–$12,000/year
Service vehicle (van or truck)	$20,000–$45,000
Plumbing tools and equipment	$5,000–$20,000

Total estimated startup cost (solo master plumber): $12,000–$30,000

That range assumes you’re buying used or mid-grade equipment and a used service vehicle. A new van and a full set of new tools pushes you toward the top of that range fast. Most plumbers launching solo already own a truck and a toolset — that’s the single biggest variable in what it actually costs you to open your doors.

The licensing fees themselves are modest. The $297 in application and exam fees ($30 + $267) is nothing compared to what you’ll spend on the vehicle. Don’t let the paperwork feel like the obstacle — the real investment is equipment and insurance.

The Realistic Timeline

You can’t shortcut the experience requirements. Five years minimum, and that’s assuming you pass both exams on the first attempt.

But you can plan ahead. While you’re working as a journeyman, start tracking your experience documentation. Keep records of the projects you’ve worked, the systems you’ve installed, the years logged. The Division will ask you to document your experience when you apply for the master exam.

And while you’re in that two-year journeyman window, start learning the business side. Learn how to estimate jobs, how to price service calls, how to manage cash flow when customers pay on 30-day terms. The license gets you legal. The business knowledge is what keeps you profitable.

When you’re ready to file, start with the LLC at ecorp.sos.ga.gov, then get your EIN at irs.gov/ein, then register at gtc.dor.ga.gov, then handle your local occupation tax certificate. That sequence gets you legally operating as a business entity in Georgia.
