Georgia septic regulations are set by the Department of Public Health under Chapter 511-3-1 of the Georgia Compilation of Rules and Regulations. Unlike states with no statewide code, Georgia maintains a uniform framework that all 159 counties must follow. The DPH writes the rules, and the county Boards of Health — organized into 18 public health districts — handle local permitting, inspections, and enforcement.
The governing technical document is the Manual for On-Site Sewage Management Systems, updated to June 2025 at 289 pages. Whether you are installing a new system, modifying an existing one, or just trying to stay compliant, this guide breaks down the georgia septic regulations that affect homeowners the most.
Georgia's dual-authority structure keeps the georgia septic regulations consistent at the state level while allowing county health departments to handle day-to-day administration. The DPH promulgates rules, certifies contractors, and publishes the technical manual. County Boards of Health issue permits, conduct inspections, and investigate complaints.
The formal georgia septic rules under Chapter 511-3-1 were last revised effective January 1, 2016. Key provisions include:

Every county follows the same basic process for issuing septic permits, though timelines and fees can vary slightly between health districts. Here is what to expect when applying for a permit under the georgia septic permit requirements.
Step 1: Contact your county health department. Reach out to the environmental health division in your county. They will explain the application forms, required documents, and current processing times. Georgia has 159 county Boards of Health organized into 18 districts — find yours through the DPH website.
Step 2: Schedule the site evaluation. A county sanitarian visits your property to assess soil conditions, groundwater levels, and available space. They dig test pits and evaluate percolation rates. Georgia's three geological provinces — Blue Ridge, Piedmont, and Coastal Plain — create wildly different soil conditions, so the evaluation determines which system type your property can support.
Step 3: Submit the permit application. You will need a completed application, site plan showing the proposed system location, property boundaries, well locations, and setback distances. Bedroom count determines the required tank and drain field size.
Step 4: System design and review. A certified installer or designer creates a system plan matching the soil evaluation results. The county health department reviews the design for code compliance. Standard permits cost $100.
Step 5: Installation and inspections. The certified installer builds the system. Two inspections are mandatory — pre-construction verification and final inspection before any backfill. Backfilling before inspection can result in forced excavation at your expense.
Most counties process permits within 2 to 6 weeks. Growth counties like Forsyth, Cherokee, and Gwinnett may have longer wait times due to development volume. Plan accordingly if you are building or closing on a property.
Georgia DPH certifies six categories of septic professionals under Rule 511-3-1-.16. Understanding these categories helps you hire the right person for the job — and verify they are actually certified.
| Category | What They Do | Exam Required | CE Hours (per 2-yr cycle) |
|---|---|---|---|
| Septic Tank Installers | Install, modify, repair systems | Residential Exam (70% to pass) | 8 hours |
| Septic Tank Pumpers | Pump and haul septage | Pumper Exam | 6 hours |
| Inspectors | Conduct system inspections | DPH certified | Varies |
| Maintenance Personnel | Maintain existing systems | DPH certified | Varies |
| Level III Soil Classifiers | Classify soils for site evaluations | 4 years coursework | 30 hours |
| Portable Sanitation Contractors | Portable sanitation services | Separate Chapter 511-3-6 | Varies |
Individual certification costs $100 per 2-year cycle. Company certification runs $400 for installers or pumpers, $800 for both. All certifications expire February 28 on even-numbered years. The DPH publishes downloadable lists of every certified installer and pumper at dph.georgia.gov/environmental-health/certification-information.
The Georgia Onsite Wastewater Association (GOWA) with roughly 473 members provides continuing education courses alongside North Georgia Technical College and the Southeastern Building Trade Association. GOWA membership is not required but signals a contractor who invests in ongoing education.
Georgia does not require mandatory point-of-sale septic inspections at the state level. No specific counties have been identified as having codified such ordinances. However, FHA, VA, and most conventional lenders require proof of a functioning septic system before approving a mortgage. This creates de facto inspection demand for the majority of property transfers.
County Environmental Health offices provide Performance Evaluation Reports (Form 14.L) for existing systems, typically costing $400 to $600. These reports assess tank condition, drain field function, and overall system health. Even when not legally required, a septic inspection protects both buyers and sellers from expensive surprises after closing.
Sellers who can produce pumping records and a recent inspection report move through due diligence faster. For a detailed walkthrough of the inspection process, read our Georgia septic inspection for home sales guide.
While the DPH sets statewide georgia septic regulations, your day-to-day experience with the GA septic code depends on your local health district. Georgia's 159 counties are organized into 18 public health districts, each with its own staff, processing times, and local procedures.
The districts that handle the most septic permits tend to be in high-growth areas around metro Atlanta. Cherokee, Forsyth, Gwinnett, and Hall counties process a disproportionate share of the state's permit applications due to rapid residential development. Rural South Georgia districts handle fewer permits but cover more geographic area, which can mean longer wait times for site evaluations.
Contact the State Environmental Health Office at (404) 657-6534 or onsite@dph.ga.gov if you need help identifying your district or resolving a dispute with your local health department.

Georgia does not mandate point-of-sale septic inspections at the state level. However, FHA, VA, and most conventional lenders require proof of a functioning system. County health departments provide Performance Evaluation Reports (Form 14.L) for $400 to $600. Even without a legal mandate, most real estate transactions involving septic systems include an inspection as part of due diligence.
A standard septic permit costs $100 in Georgia. Total costs including the site evaluation, design review, and construction inspections typically run $300 to $700 depending on the county and system complexity. Growth counties with high demand may have higher total costs due to additional review steps.
Installing without a permit violates Chapter 511-3-1 and can result in fines, a stop-work order, and a requirement to excavate and rebuild the system to code. The county Board of Health has enforcement authority and can refer violations to the state. The financial risk far outweighs the $100 permit fee.
Georgia does not prohibit septic additives, but the DPH does not endorse them either. The Manual for On-Site Sewage Management Systems makes no recommendation for additives. Most septic professionals advise against chemical additives because they can disrupt the natural bacterial balance in the tank and potentially damage drain field soils.
Georgia septic permits are valid for a maximum of 12 months from the date of issue. If construction is not completed within that window, you must apply for a new permit. Extensions are generally not available — the county will require a new site evaluation if conditions may have changed.
