Getting a georgia septic permit is the mandatory first step before any new septic system goes in the ground, any existing system gets modified, or any major repair takes place. The permit costs $100 through the DPH and is valid for 12 months. The process takes 2 to 6 weeks depending on your county's workload, and skipping it exposes you to fines, stop-work orders, and potential system removal.
Georgia's 159 county Boards of Health — organized into 18 public health districts — handle all septic permitting locally. The statewide DPH rules under Chapter 511-3-1 set the framework, but your county's environmental health office is where the permit application, site evaluation, and inspections actually happen. This guide walks you through each step of the georgia septic permit process from start to finish.
Every county follows the same basic sequence mandated by the DPH. The details and timelines vary, but the steps are consistent statewide.
Step 1: Contact your county environmental health office. Call or visit the environmental health division of your county Board of Health. They will provide the application form, explain required documents, and tell you the current wait time for site evaluations. Most counties have this information on their websites, but calling confirms you have the latest version of forms and current fee schedules.
Step 2: Submit the permit application. The georgia septic permit application requires property owner information, a site plan showing the proposed system location, property boundaries, all existing wells and water features, building locations, and setback distances. You will also need the number of bedrooms (which determines tank and drain field sizing) and the property deed or tax parcel number.
Step 3: Schedule the site evaluation. The county sends a registered sanitarian to your property. This is the critical step — the site evaluation determines what type of system your property can support. The sanitarian digs test pits (typically 2 to 4) and evaluates soil texture, color, structure, depth to rock, and depth to seasonal high water table.
Step 4: Receive the soil evaluation results. The county provides written results classifying your soil and specifying which system types are approved for your site. On Georgia's three geological provinces, results vary dramatically. Piedmont clay sites often get limited to mound or ATU systems. Coastal Plain sand sites usually qualify for conventional systems. Blue Ridge mountain sites depend on soil depth over bedrock.
Step 5: System design. A DPH-certified installer or a Level III Soil Classifier designs the system based on the soil evaluation. The design must include tank sizing, drain field dimensions, setback compliance, and construction details. Complex sites requiring engineered alternative systems may need a separate design by a licensed professional engineer.
Step 6: Design review and permit issuance. Submit the design to the county for review. The sanitarian checks it against the soil evaluation results and DPH requirements. Once approved, the county issues the construction permit. Standard permits cost $100.
Step 7: Construction with mandatory inspections. Your certified installer builds the system. Two inspections are required: a pre-construction site verification (confirming the layout matches the permitted design) and a final construction inspection before any backfill. Backfilling before the final inspection can result in forced excavation at your expense.
Step 8: Final approval and documentation. After passing the final inspection, the county issues an approval document. Keep this with your property records — you will need it for real estate transactions, refinancing, and any future system modifications.
The GA septic permit process timeline depends on your county's workload and the complexity of your site. Here is what to expect.
| Step | Typical Timeline | Cost |
|---|---|---|
| Application submission | Same day | $100 (permit fee) |
| Site evaluation scheduling | 1–4 weeks | $200–$500 (evaluation fee) |
| Soil results | 1–2 weeks after evaluation | Included |
| System design | 1–2 weeks | $300–$800 (complex systems) |
| Design review | 5 business days to 3 weeks | Included with permit |
| Construction + inspections | 2–5 days construction | Included with permit |
Total timeline: 2 to 6 weeks for most projects. High-growth counties like Forsyth, Cherokee, and Gwinnett may have longer wait times during peak building season (March through October). Plan ahead — especially if you are building a new home and the septic permit is on the critical path for your construction schedule.
The $100 permit fee is just the base. Here is the complete georgia septic permit cost picture including all related expenses.
Minimum total cost (simple conventional system): $400 to $700. This covers the permit fee, site evaluation, and basic design review for a straightforward site with good soil that qualifies for a conventional gravity system.
Moderate total cost (LPP or chamber system): $600 to $1,200. Sites with marginal soils that need low-pressure pipe or chamber systems require more detailed design work and potentially a Level III soil classification.
High total cost (mound, ATU, or drip system): $800 to $2,500. Complex sites on Piedmont clay or mountain bedrock may need Level III soil classification ($500 to $1,500 with mandatory $1 million liability insurance), professional engineering design, and multiple review cycles.
Navigating how to get septic permit georgia approval smoothly means avoiding the pitfalls that delay projects and increase costs.
Don't start any work before the permit is in hand. No digging, no clearing, no equipment staging on the drain field area. Any disturbance to the site before evaluation can void the soil results and require starting over.
Don't assume your lot can support a conventional system. Many first-time builders on Georgia Piedmont clay are surprised to learn their property requires a $15,000 mound system instead of a $7,000 conventional one. Get the site evaluation done before you finalize your building budget.
Don't ignore setback requirements. Georgia requires 50 feet from wells to tanks, 100 feet from wells to drain fields, and 150 feet from cesspools. On small lots, these setbacks sometimes make it impossible to locate both a well and septic system. Verify setback compliance before purchasing a property you plan to develop.
Don't skip the pre-construction inspection. Some contractors try to accelerate the schedule by backfilling before the inspector arrives. This is a violation that can result in forced excavation, repermitting, and significant cost increases.

Yes. Property owners can submit the permit application directly to their county health department. However, the system design must be prepared by a DPH-certified installer or professional, and all construction must be performed by a certified contractor. Most homeowners have their installer handle the entire permit process as part of the project.
Failing the site evaluation does not necessarily mean you cannot build. It means a conventional system is not feasible. Alternative systems — mound, ATU, drip irrigation — can work on properties that fail conventional evaluation. The county will specify which alternatives are approved. Only in rare cases of extreme soil limitations or space constraints is a property truly unbuildable from a septic standpoint.
Septic permits are generally tied to the property, not the owner. If you sell a property with an active permit, the new owner can typically use it to complete the installation within the 12-month validity period. Check with your county health department for specific transfer procedures — some counties require written notification of the ownership change.
Minor repairs like replacing a pump, fixing a pipe, or cleaning a distribution box generally do not require a new permit. Major modifications — replacing the drain field, changing the system type, or relocating components — do require a permit. When in doubt, call your county environmental health office before starting work. An unpermitted modification can create serious problems during a future property sale.
