Georgia Contractor Licensing Requirements

The Georgia contractor licensing framework

Georgia regulates contractors at the state level under O.C.G.A. § 43-41, administered by the State Licensing Board for Residential and General Contractors (a Professional Licensing Board within the Secretary of State's office). The statute creates two principal license classes for general construction — Residential and General Contractor — with the residential class subdivided into Residential Basic and Residential Light Commercial. Specialty trades (electrical, plumbing, HVAC, low voltage, utility) are licensed under separate statutes and boards.

For most contractors, licensure is not optional. Performing work above the statutory threshold without the correct license is a criminal offense under O.C.G.A. § 43-41-17 and forfeits civil enforcement rights — most consequentially the ability to file or perfect a mechanic's lien.

License classes for general construction

Residential Basic Contractor (RBC)

The RBC license authorizes:

One- and two-family residential dwellings up to three stories
Detached single-family homes and townhomes
Accessory residential structures

Application requirements: 2 years of demonstrated experience; passing the RBC exam administered by PSI Services; financial-responsibility documentation (typically a net worth threshold and credit review); proof of general liability insurance; surety bond where applicable; the application fee.

Residential Light Commercial Contractor (RLCO)

The RLCO license authorizes all RBC-eligible work plus light commercial structures up to three stories and 25,000 square feet — covering most strip-center retail, small office, and light institutional construction. The application process mirrors RBC with a more demanding experience requirement and a more rigorous exam.

General Contractor (GC)

The GC license covers all construction work other than single-family residential dwellings — including commercial, industrial, multi-family residential (4+ units), and institutional work. There is no project-size cap. Requirements:

2+ years of commercial construction experience (employee for a licensed contractor, supervisory role, or equivalent)
Passing the General Contractor exam administered by PSI
Audited or reviewed financial statement demonstrating net worth above the Board's threshold (subject to periodic update)
Proof of general liability insurance at the required limits
Application fee and biennial renewal fee

Specialty trade licenses (separate from § 43-41)

The following Georgia trades have their own state licensing boards under separate statutes:

Electrical Contractor (Division I, II) — Georgia State Construction Industry Licensing Board, Division of Electrical Contractors, under O.C.G.A. § 43-14. Division I covers low voltage; Division II covers full electrical work.
Master and Journeyman Plumber — Division of Master Plumbers and Journeyman Plumbers under O.C.G.A. § 43-14. Master Plumber is required to operate a plumbing contracting business.
Conditioned Air Contractor (HVAC) — Class I (under 175,000 BTU) and Class II (no limit) — under O.C.G.A. § 43-14. The exam covers refrigeration, sheet metal, controls, and code.
Low Voltage Contractor — for security alarm, telecommunications, and similar systems.
Utility Contractor — for water and sewer mains and similar underground utility work.

License-number disclosure requirements

Under O.C.G.A. § 43-41-17 and Board rules, the contractor's license number must appear on:

All written contracts, including residential contracts above $2,500
All written proposals and estimates
All advertising — print, online, signage, and vehicle lettering
All invoices and statements
All permit applications

Failure to include the license number on a contract can void the contract from the contractor's side — meaning the contractor cannot enforce payment or assert lien rights, while the homeowner retains warranty and quality remedies. The Board treats license-number-disclosure violations as a routine basis for disciplinary action.

Residential contract requirements (O.C.G.A. § 43-41-17(b))

For any residential construction contract above $2,500, Georgia law requires a written contract containing:

Description of the work to be performed
Total contract price
Estimated dates of commencement and substantial completion
Payment terms and schedule
Contractor's license number
Contractor's full business name and address
Homeowner's name and address

Beyond the statutory minimum, a defensible Georgia residential contract typically also includes warranty terms (Right to Repair Act considerations under O.C.G.A. § 8-2-35), change-order procedure, dispute-resolution clause, and an attorney-fees provision.

Mechanic's lien rights — license is the prerequisite

Georgia mechanic's lien law (O.C.G.A. § 44-14-361 et seq.) provides contractors with a powerful payment-collection tool — but only if the contractor was properly licensed for the work performed. Under § 44-14-361.5 and the Georgia courts' consistent interpretation, an unlicensed contractor performing work that required a license cannot file or enforce a lien. Filing a false lien (including a lien by an unlicensed contractor) exposes the filer to additional liability.

The lien-filing process in Georgia is procedurally strict:

Notice of Commencement filed by the owner within 15 days of physically commencing work (for residential).
Notice to Contractor required from materialmen and subcontractors who do not have a direct contract with the owner.
Claim of Lien filed in the county where the property is located within 90 days from when the labor/materials were last provided.
Notice of Filing of Claim of Lien sent to the owner within 2 business days.
Action to enforce the lien must be commenced within 365 days of filing.

Missing any of these deadlines forfeits the lien — Georgia courts will not extend the windows for equitable reasons.

Georgia contractor licensing FAQs

Who needs a Georgia contractor license?

Under O.C.G.A. § 43-41, anyone who undertakes to perform a contracting service on a building in Georgia for compensation must hold the appropriate license, with limited exceptions for owner-occupants, work under a specified small-job threshold, and certain pre-construction services. The licensing scheme is administered by the State Licensing Board for Residential and General Contractors, a division of the Secretary of State's Professional Licensing Boards Division.

What is the difference between a Residential Basic and Residential Light Commercial license?

A Residential Basic Contractor license (RBC) authorizes work on single-family detached homes, townhomes, and one- to two-family residential structures. A Residential Light Commercial Contractor license (RLCO) covers all RBC work plus light commercial structures up to three stories and 25,000 square feet. The RBC is more restrictive and slightly easier to obtain; the RLCO allows commercial expansion without requiring a full general contractor license.

What does a General Contractor license allow in Georgia?

The General Contractor license (GC) covers all construction work other than single-family residential dwellings — including commercial, industrial, multi-family residential (4+ units), and institutional work. There is no project-size cap. Applicants must demonstrate 2+ years of experience, pass the General Contractor exam (currently administered by PSI), and show financial responsibility (financial statement with net worth typically required to exceed a specified threshold).

How much experience do I need to apply for a Georgia contractor license?

For Residential Basic and Residential Light Commercial: 2 years of proven experience in residential construction, supervisory work, or related fields. For General Contractor: 2 years of experience in commercial construction or equivalent. Experience can include working as an employee for a licensed contractor, holding a related degree (counting for credit), or having held a license in another state. The application requires affidavits from previous employers or general contractors documenting the experience.

What other Georgia trades require state licenses?

Several specialty trades have their own state licensing boards: Electrical (Georgia State Construction Industry Licensing Board, Division of Electrical Contractors), Plumbing (Division of Master Plumbers and Journeyman Plumbers), Conditioned Air Contractors (HVAC), Low Voltage, and Utility Contractor work. These licenses are separate from and in addition to the general/residential contractor licenses. Some city/county jurisdictions also require local registration even for state-licensed contractors.

What is the Georgia residential contractor contract requirement?

Under O.C.G.A. § 43-41-17(b), every residential contract that exceeds $2,500 must be in writing. The required contract content includes a description of the work, the contract price, the dates of commencement and substantial completion, payment terms, and the contractor's license number. Failure to include the license number is a violation of the licensing act and can void enforcement rights against the homeowner.

Can I file a mechanic's lien in Georgia without a license?

No. Under O.C.G.A. § 44-14-361.5 and Georgia case law, an unlicensed contractor performing work that required a license cannot enforce the contract or assert a mechanic's lien. The lien filing itself may be void, and the unlicensed contractor may be liable for filing a false lien. Licensure is a fundamental prerequisite to lien rights — the state takes this rule seriously and enforces it through both the licensing board and the courts.

What goes on a Georgia contractor estimate or proposal?

A defensible Georgia contractor estimate should include: full business name and address; contractor license number (RBC, RLCO, GC, or specialty); scope of work with measurable deliverables; itemized cost breakdown; total price; payment schedule consistent with O.C.G.A. § 43-41-17 disclosures; estimated start and completion dates; warranty terms; and a statement of any exclusions. For residential work above $2,500, the proposal often serves as the basis for the written contract; clarity at this stage prevents disputes downstream.
