Georgia residential building code
- Code
- 2024 International Residential Code with Georgia amendments (Georgia State Minimum Standard Codes)
- How it applies
- Statewide, mandatory everywhere
- Coming next
- Georgia's current-codes page already lists the 2024 IRC, but a December 9, 2025 state notice gives January 1, 2027 as its effective date
- Code agency
- Georgia Department of Community Affairs (DCA), Construction Codes Program
- Who enforces it
- The IRC is a mandatory state code: homes must comply whether or not the city or county enforces it. Local governments choose whether to run permits and inspections. Georgia uses the IPC, NEC and 2015 IECC instead of the IRC's plumbing, electrical and energy chapters.
- Good to know
- Georgia has adopted the 2024 IRC with Georgia amendments, and it applies statewide even where a county doesn't inspect. The state's own pages give different start dates (January 2026 and January 2027), so ask your local building department which edition it's enforcing on your permit. Georgia uses separate state codes for plumbing, electrical and energy.

Frost line depth in Georgia
- Who sets it
- Local building department
- Local examples
- City of Alpharetta: 5 in. frost line (12 in. minimum footing depth)
Macon-Bibb County: 18 in.
Rome / Floyd County: 12 in. minimum - Typical range
- 5-18 in. in the jurisdictions listed; Alpharetta and Rome/Floyd County state a 12 in. minimum footing depth
- Good to know
- Fayette County also lists a 5 in. frost line. Alpharetta's figures are for the 2024 IRC with Georgia amendments (revised 2026).

Retaining wall permits in Georgia
- Permit exemption
- Set locally. Georgia's IRC amendments delete Chapter 1 (incl. R105.2) and keep it only as a reference and guide for local governments; this amendment was carried forward for the 2024 code.
- Who decides
- Your city or county adopts its own administrative and permit rules and decides.
- Good to know
- Georgia leaves permit rules to cities and counties. Ask your local building department whether your wall needs a permit.

811 dig law in Georgia
- One-call center
- Georgia 811 (Utilities Protection Center)
- Notice before digging
- Not less than 2 nor more than 8 business days, starting 7:00 a.m. the first business day after the request
- Ticket good for
- 30 calendar days after the locate request's effective date
- Hand-dig zone
- Facility width plus 18 in. on either side of the outside edge (horizontal plane)
- Homeowners
- No call legally required for non-mechanized digging. 'Excavating' means using mechanized equipment or explosives; Georgia 811 says Georgia law does not require notice for 'a smaller, non-mechanized digging project' but encourages it. Farming activities are excluded. Anyone using mechanized equipment (including homeowners renting an auger or mini-ex) must call.
- The law
- O.C.G.A. § 25-9-1 et seq.
- Good to know
- Because the count starts the next business day, a request made today clears no earlier than the morning of the 3rd business day. Work done only with minimally intrusive methods needs no notice.
Drainage law and stormwater permits in Georgia
- Rule
- Civil law (natural flow)
- The rule
- Civil law (natural flow): the lower lot must accept water that naturally flows from the higher lot, but the upper owner may not collect and concentrate water and discharge it in greater quantity or in a different manner than nature would. (Label assigned from the rule; the opinion does not name a doctrine.)
- Leading case
- Terry v. Catherall. Ga. Ct. App. No. A16A0353 (July 12, 2016); quoting Green v. Eastland Homes, 284 Ga. App. 643 (2007) and Sumitomo Corp. of America v. Deal, 256 Ga. App. 703 (2002)
- What it means for your yard
- Your neighbor below has to accept water that naturally runs off your lot, but if you regrade, pipe downspouts or add a patio that collects water and sends more of it, or sends it in a new way, onto their land, you can be liable.
- Construction stormwater permit
- Georgia Environmental Protection Division (EPD); certified counties and cities act as local issuing authorities for land-disturbance permits under the Erosion and Sedimentation Act (O.C.G.A. 12-7-1 et seq.): 1 acre or more of land disturbance for stand-alone projects (GAR100001, effective Aug. 1, 2023 to July 31, 2028); common developments are covered under GAR100003 and infrastructure under GAR100002
- State rules below 1 acre
- Georgia's Erosion and Sedimentation Act requires a land-disturbing activity permit from the local issuing authority (or notice to EPD) unless an exemption applies. Projects disturbing less than 1 acre are exempt unless they are within 200 feet of the bank of any state waters or part of a larger common plan of 1 acre or more; single-family homes disturbing less than 1 acre (not part of a larger plan) are exempt but must still meet the Act's minimum erosion-control requirements (O.C.G.A. 12-7-7, 12-7-17).
- Local rules
- Georgia counties and cities that are certified issuing authorities issue land-disturbance permits and often have their own grading and stormwater ordinances.
- Good to know
- In Georgia the lower lot must take natural runoff, but you can't collect water and dump more of it, or in a new way, onto a neighbor. State construction stormwater permits start at 1 acre, and a local land-disturbance permit can be needed for smaller jobs within 200 feet of a creek or other state waters.
Contractor licensing in Georgia
- Statewide rule
- License
- Agency
- Georgia State Licensing Board for Residential and General Contractors (Secretary of State)
- Who needs it
- Residential contractors (residential-basic or residential-light commercial work) need a state license when the work's value or compensation exceeds $2,500; commercial general contractors also need a state license. Owners may build on their own property for their own use, but an owner who sold an owner-built structure within the prior 24 months cannot use the exemption again.
- When it applies
- Residential work where the greater of the total value of the work or the contractor's compensation exceeds $2,500
- Check a contractor
- Official lookup
- Licensed separately
- Electrical, plumbing, conditioned air, low-voltage and utility work must be done by persons licensed under O.C.G.A. Title 43, Chapter 14; specialty-trade work does not need this license, according to the Secretary of State's FAQ.
- Good to know
- The $2,500 residential threshold is in O.C.G.A. 43-41-2(9) and dates to July 1, 2008. A 2024 amendment changed the term general contractor to commercial general contractor, and that category has no dollar threshold.

Contractor deposits and your right to cancel in Georgia
- Deposit limit
- No statewide cap.
- Right to cancel
- No general state home-solicitation law; the federal 3-day Cooling-Off Rule covers sales made at your home. Since July 1, 2023, Georgia law adds a 30-business-day cancellation right for in-home sales with payments over $10,000 under a lease longer than 120 months that is (or is claimed to be) eligible for federal tax credits, which mainly affects solar sales.
- The law
- Georgia Fair Business Practices Act (2023 door-to-door expansion; section not cited on the state page); 16 C.F.R. Part 429 (federal Cooling-Off Rule)
- Good to know
- Georgia relies on the federal 3-day Cooling-Off Rule for most contracts signed at home. Long-term solar leases over $10,000 sold at your door carry a 30-business-day cancel right.

Mechanics lien deadlines in Georgia
- Lien deadline (prime)
- File the claim of lien with the superior court clerk within 90 days after completing the work or furnishing the materials, and send the owner a copy within 2 business days by registered or certified mail or overnight delivery (O.C.G.A. § 44-14-361.1(a)(2)).
- Lien deadline (sub/supplier)
- Same as prime; also send a copy to the contractor if a notice of commencement was filed (O.C.G.A. § 44-14-361.1).
- Preliminary notice (sub/supplier)
- If a notice of commencement was filed, claimants without privity with the contractor must send the owner and contractor a notice to contractor within 30 days after the later of the NOC filing or first furnishing; if no NOC was filed, the requirement doesn't apply (O.C.G.A. § 44-14-361.5). Optional preliminary notice of lien (§ 44-14-361.3).
- Notice of intent
- Not required.
- Enforce within
- Lien action within 365 days after filing the claim, and a notice of the action filed with the clerk within 30 days after starting it (O.C.G.A. § 44-14-361.1).
- Homeowner rules
- A lien is dissolved if, at final payment, the owner obtained the contractor's sworn statement that the claimant was paid or waived and no preliminary notice or lien was of record (O.C.G.A. § 44-14-361.2). A claim missing the statutory notice of the owner's right to contest is invalid (§ 44-14-361.1).
- The law
- O.C.G.A. Title 44, Ch. 14, Art. 8, Part 3 (Mechanics and Materialmen), §§ 44-14-360 to 44-14-369
- Good to know
- Georgia gives 90 days after your last work to file and a year to sue. If a notice of commencement is posted, subs and suppliers without a direct contract with the general contractor must send a notice to contractor within 30 days.

Workers' comp requirements in Georgia
- Who must carry it
- Employers who regularly employ 3 or more people in Georgia, full- or part-time, must carry coverage; corporate officers and LLC members count toward the 3 (Georgia SBWC). No separate construction threshold.
- Owners and officers
- Corporate officers and LLC members are employees, but up to five may waive coverage on themselves by filing Form WC-10 with the insurer; a waiver does not reduce the employee count. Sole proprietors and partners are employers, not employees, but may elect coverage in writing to their insurer (Georgia SBWC FAQ).
- Subcontractors
- A contractor who sublets work may be liable for coverage of an uninsured subcontractor's employees, and its insurer can charge premium for payments to uninsured subs (Georgia SBWC employer pamphlet).
- Penalties
- Civil penalty of $500 to $5,000 per occurrence; a 10% increase in compensation if the employer willfully fails to insure; willful failure is a misdemeanor with a fine of $1,000 to $10,000, up to 12 months in jail, or both (Georgia SBWC employer pamphlet, rev. 7/23).
- The law
- O.C.G.A. Title 34, Ch. 9 (Workers' Compensation)
- State agency
- Georgia State Board of Workers' Compensation
- Good to know
- Georgia requires coverage once you regularly have 3 or more workers, counting part-timers and corporate officers. A general contractor can be liable for an uninsured sub's workers.
