Licensing
Master License Requirements for Georgia Plumbers, Electricians & HVAC Contractors
- Plumbing, electrical, and conditioned-air (HVAC) each require their own state license in Georgia — none of them is covered by a general or residential contractor license.
- These trade licenses are separate master/journeyman licenses, distinct from the Residential-Basic, Residential-Light Commercial, and General tiers issued to building contractors.
- A master license and a journeyman license are different tiers with different scopes of authority and supervision requirements.
- Unlicensed trade work carries penalties and can jeopardize your ability to enforce a contract or a mechanic's lien for that work.
- A complaint filed against your license with the state board can threaten your ability to keep operating, so it should never be ignored.
If you run a plumbing, electrical, or HVAC business in Northeast Georgia, you already know the state cares about who's allowed to touch a gas line, a breaker panel, or a condensing unit. What surprises a lot of trade contractors is how separate that licensing structure is from the general and residential contractor licenses everyone talks about. Holding one doesn't automatically qualify you for another, and mixing them up can put a job — and your ability to get paid for it — at risk.
This post walks through how Georgia licenses the mechanical trades: plumbing, electrical, conditioned-air (HVAC), and low-voltage work, how master and journeyman tiers differ, where local and municipal rules layer on top, and what happens when a license-board complaint or unlicensed work lands on your desk.
The mechanical trades are licensed separately from general contractors
Georgia's State Licensing Board for Residential & General Contractors licenses contractors who build, remodel, or manage residential and general construction projects over $2,500. That license structure — Residential-Basic, Residential-Light Commercial, and General — governs who can contract to build or renovate a structure.
Plumbing, electrical, and conditioned-air (HVAC) work are governed by their own separate master and journeyman licenses. A general contractor's license does not authorize you to personally perform licensed plumbing, electrical, or HVAC work, and a plumbing or electrical license does not qualify you to act as a general contractor. Many trade businesses hold multiple licenses, or bring in a separately licensed subcontractor for work outside their own trade — and that distinction matters when a contract, a lien, or a customer dispute is on the line.
Plumbing licenses: journeyman, master, and general
Plumbing work in Georgia is licensed at different tiers, reflecting different levels of experience and scope of authority. A journeyman plumber generally works under the supervision of a master or contractor-level license, while a master plumbing license allows broader authority to perform and oversee plumbing work, including pulling permits and supervising others.
If your business performs plumbing installation, repair, or alteration — water supply lines, drain-waste-vent systems, gas piping, fixtures — the person responsible for that work needs to hold (or work under someone who holds) the appropriate plumbing license for the scope of the job.
Electrical licenses
Electrical work has its own licensing track, separate from both plumbing and HVAC. As with plumbing, Georgia distinguishes between journeyman-level electrical work performed under supervision and master-level electrical licensure, which carries broader authority over electrical installations, alterations, and repairs.
Wiring a panel, running new circuits, or performing service upgrades is electrical trade work that requires the appropriate license — it isn't something a general or residential contractor's license covers on its own, even if the contractor is managing the overall project.
Conditioned-air / HVAC licenses
Heating, ventilation, and air-conditioning work — what Georgia often refers to as conditioned-air work — is licensed as its own trade category as well. Installing, servicing, or replacing HVAC systems, including work involving refrigerant lines and gas-fired equipment, requires the appropriate conditioned-air license, again separate from a general contractor's credential.
Because HVAC work frequently overlaps with electrical connections and, in the case of gas furnaces, gas piping, HVAC contractors should be clear on where their own license's scope ends and where a separately licensed electrician or plumber needs to be brought in.
Low-voltage licensing
Georgia also recognizes low-voltage licensing as a distinct category from standard electrical licensure. Low-voltage work — think security systems, data cabling, fire alarm wiring, and similar systems operating below standard line voltage — is treated separately from full electrical licensing, and contractors performing that work should hold the license category that actually matches what they're installing.
It's a common point of confusion: a standard electrical license doesn't automatically cover low-voltage work, and a low-voltage license doesn't authorize line-voltage electrical work. Matching the license to the scope of the job protects both the contractor and the customer.
Local and municipal requirements layer on top of state licensing
Holding a state-issued plumbing, electrical, or conditioned-air license doesn't necessarily mean you're automatically cleared to pull permits and perform work in every city or county in Northeast Georgia. Many local jurisdictions maintain their own permitting processes, business licenses, or registration requirements on top of state trade licensure.
- Check permit and registration requirements in each jurisdiction where you plan to work, not just your home base.
- Keep your state license number current in local permit systems — expired or mismatched license information can hold up permits and inspections.
- Coordinate with general contractors and property owners on who is responsible for pulling which permits before work starts, not after an inspector flags a problem.
License-board complaints and how they're defended
A complaint filed against your license — whether from a customer, a competitor, an inspector, or the board itself — is not something to shrug off. Depending on the allegations, a board investigation can lead to consequences ranging from a formal reprimand to suspension or revocation of your license, which can shut down your ability to operate.
If you're facing a license-board complaint, the process typically involves responding to the board's inquiry, presenting your side of the facts, and in some cases appearing at a hearing. How that response is handled — what's said, what's documented, what's admitted — can shape the outcome. Getting a business law attorney involved early, rather than after a decision has already been made against you, gives you the best chance to protect your license.
Penalties for unlicensed work
Performing plumbing, electrical, or HVAC work without the required license carries real consequences beyond the risk of a board complaint. Unlicensed trade work can expose you to penalties, and — just as with unlicensed general contracting — it can undermine your ability to enforce your contract or collect payment, including through a mechanic's lien, for work performed without the proper license.
If you're a business owner who subcontracts trade work, it's worth confirming that the subcontractors on your jobs are properly licensed for the scope of work they're performing. Using an unlicensed sub doesn't just expose them — it can create liability and payment headaches for you as well.
When to call a lawyer
Licensing questions come up at the worst possible moments — mid-bid, mid-permit, or after a customer dispute has already turned into a board complaint. Whether you're structuring a multi-trade business, sorting out which license covers a scope of work, or responding to a complaint that could threaten your license, it helps to have someone who understands both the trades and Georgia's licensing framework.

Frequently Asked Questions
Do I need a master license for HVAC work in Georgia?
Georgia licenses conditioned-air (HVAC) work separately from plumbing, electrical, and general contracting. Depending on the scope of work and your role, you may need a master-level conditioned-air license or may be able to work as a journeyman under a licensed supervisor — but HVAC work isn't covered by a general contractor's license alone.
Is a plumbing license separate from a general contractor license?
Yes. Georgia's plumbing licenses are entirely separate from the Residential-Basic, Residential-Light Commercial, and General contractor licenses issued by the State Licensing Board for Residential & General Contractors. A general contractor's license does not authorize you to personally perform licensed plumbing work.
What's the difference between a journeyman and a master license?
A journeyman license generally allows you to perform trade work under the supervision of a master-level or contractor-level license holder, while a master license carries broader authority — including supervising others and, typically, pulling permits. The tiers reflect different levels of experience and independent authority within the same trade.
What happens if I do trade work without a license?
Performing plumbing, electrical, or HVAC work without the required license can expose you to penalties and can undermine your ability to enforce your contract or collect payment — including through a mechanic's lien — for that work. It can also trigger scrutiny from the licensing board.
Can a license-board complaint cost me my license?
Yes, depending on the allegations and how the board proceeds, a complaint can lead to consequences ranging from a reprimand to suspension or revocation of your license. Responding promptly and thoughtfully — ideally with legal guidance early in the process — gives you the best chance to protect your ability to keep operating.
