How to Start a Plumbing Business in Georgia (2026)
Key takeaways
- Plumbing is a separately state-licensed trade in Georgia — the Master Plumber credential from the Construction Industry Licensing Board is required to run a plumbing business, regardless of job size.
- Class I (Restricted Master) covers single-family and buildings four stories or smaller; Class II (Unrestricted Master) covers any building.
- The Master license is built on prior Journeyman licensure — you work as a journeyman under a master before you qualify to run your own shop.
- Your GA LLC is filed with the Secretary of State; Georgia charges a $50 annual registration, and workers' comp is required at three or more employees.
What do you need to start a plumbing business in Georgia?
Three pieces beyond your skills: your Georgia Master Plumber license, a registered business, and insurance.
| Requirement | Georgia specifics |
|---|---|
| GA plumbing license | Master Plumber — Class I (Restricted, single-family/≤4 stories) or Class II (Unrestricted, any building), from the Construction Industry Licensing Board. Required for plumbing work of any size. |
| GA LLC | Articles of Organization filed with the GA Secretary of State. |
| EIN | Free from the IRS, same day. |
| Insurance | General liability; workers' comp once you have three or more employees. |
How do you get a plumbing license in Georgia?
Georgia licenses plumbing through the Construction Industry Licensing Board, and the Master Plumber credential is the qualifier for any plumbing business. Unlike a general or residential contractor — which Georgia only requires once a job hits $2,500 — plumbing is licensed for work of any size. Which class you need depends on the buildings you'll work on.
| Class I (Restricted Master) | Class II (Unrestricted Master) | |
|---|---|---|
| Applies to | Single-family and buildings four stories or smaller | Any building type, no height restriction |
| License | Master Plumber — Class I | Master Plumber — Class II |
| Experience | Prior Journeyman + ~3 years continuous Georgia journeyman experience (on top of ~4 years supervised) | Prior Journeyman + ~5 years continuous Georgia journeyman experience (on top of ~4 years supervised) |
| Exams (via PSI) | Business & Law + trade exam | Business & Law + trade exam |
| Typical cost | ~$220 exam + application fees | ~$220 exam + application fees |
Important Georgia detail: you can't jump straight to Master — you first hold a Journeyman Plumber license and work under a master, then qualify for Class I or Class II Master to run your own business. Note the contrast with a state like South Carolina, which sets low residential and commercial dollar tiers — Georgia licenses plumbing statewide with no dollar threshold. You can verify any Georgia plumbing license through the Secretary of State's online license lookup.
Plumbing is separately licensed: Georgia's $2,500 contractor threshold applies to general and residential building work — not to plumbing. Plumbing, electrical, conditioned air (HVAC), and low-voltage are all separately state-licensed regardless of job size, so there's no "under $2,500" exemption for plumbing. You need a Master Plumber license before you contract any plumbing work.
Registering your plumbing business in Georgia
- Choose and check your business name against the GA Secretary of State's records.
- The Articles of Organization — filed with the GA Secretary of State, online.
- Your registered agent (you can be your own, or use a service).
- Your federal tax ID (EIN) — free from the IRS — same day.
- Open a business bank account and set up bookkeeping.
- Get your local business license — Georgia cities and counties generally require an occupation tax certificate.
Georgia requires a $50 annual registration for your LLC each year, filed with the Secretary of State. And because plumbing is construction work, Georgia requires workers' compensation coverage once you have three or more employees — verify the current rule before you hire.

Getting your first plumbing customers in Georgia
Plumbing demand is constant and often urgent, which works in your favor. Set up a Google Business Profile for your service area (metro Atlanta, Savannah, Augusta, Columbus, or Macon), turn on Google Local Services Ads for high-intent calls, and position for 24/7 emergency work — after-hours availability commands premium pricing. Ask every satisfied customer for a review, build relationships with local supply houses like Ferguson, and line up real-estate agents and property managers for steady repair and turnover work.
Before you file: Georgia licensing classes and fees can change, and city/county business-license rules vary by location. Always confirm current requirements directly with the Georgia State Licensing Board for Residential and General Contractors and the Construction Industry Licensing Board (sos.ga.gov), the Georgia Secretary of State, and your local jurisdiction.

What license do you need for a plumbing business in Georgia?
You need a state Master Plumber license from the Construction Industry Licensing Board — the qualifier required for any plumbing company, regardless of job size. Class I (Restricted Master) covers single-family and buildings four stories or smaller; Class II (Unrestricted Master) covers any building. Both are built on prior Journeyman licensure. Confirm current rules with the Georgia State Licensing Board for Residential and General Contractors and the Construction Industry Licensing Board.
What's involved in registering a business in Georgia?
The Articles of Organization go to the GA Secretary of State, a registered agent is named (that can be you), and the IRS issues the EIN free. You remain the applicant on every filing. Georgia charges a $50 annual registration each year, and a local city or county business license (occupation tax certificate) is generally required.
Is plumbing licensed regardless of job size in Georgia?
Yes. Georgia's $2,500 threshold applies to general and residential building work, not plumbing. Plumbing is a separately state-licensed trade with no dollar threshold — the Master Plumber credential is required for any plumbing business operating in Georgia.
How long does it take to start a plumbing business in Georgia?
Once you hold your Georgia Master Plumber license, doing the setup yourself takes weeks or months, or about a week done for you when everything is run in parallel. Earning the license is the longer variable — it requires years of journeyman experience, a PSI exam, and application review.
