Upson County Septic Permits: When Health Overrides the Zoning Lot Size

Sourced from the Upson County zoning ordinance (Appendix A, Supplement No. 3, August 8, 2022), Upson County Environmental Health, the 2020 Census urban-rural classification, District 4 Public Health, and Ga. Comp. R. & Regs. 511-3-1 — last checked August 2026.

Who Issues Upson County Septic Permits

Upson is one of twelve counties in District 4 Public Health: Butts, Carroll, Coweta, Fayette, Heard, Henry, Lamar, Meriwether, Pike, Spalding, Troup and Upson.

Upson County Environmental Health: 314 East Lee Street, Thomaston, GA 30286 — (706) 647-7148
Hours: Monday to Friday, 8:00 a.m. to 5:00 p.m., closed 12:00 to 1:00
District 4 headquarters: 301 Main Street, LaGrange, GA 30240 — 706-845-4035

Why We Can’t List Upson’s Fees

District 4 publishes no septic fee schedule — not for Upson, and not for any of its twelve counties. Its application forms tell you to pay “the associated fee,” with the amount set at the county office.

Fee-setting authority in Georgia sits with each county board of health under O.C.G.A. § 31-3-4, not with the health district. That means twelve separate fee schedules inside District 4, and a figure from a neighboring county tells you nothing reliable about Upson. We would rather publish no number than the wrong one. Call (706) 647-7148 and ask.

Have ready when you call: your parcel or tax ID, whether the property is on a private well or public water, and whether you need new construction, a repair, or a modification — each carries a different fee and different soil requirements.

Environmental Health Can Require a Bigger Lot Than Zoning Does

This is the strongest local sequencing rule of any small county in District 4, and it changes how you should approach a purchase in Upson County.

The county’s zoning ordinance — Appendix A, Supplement No. 3, dated August 8, 2022 — provides that “Before a building permit is issued… the Upson County Health Department must approve the proposed water supply and sewage disposal facilities.” That establishes the ordering: health approval precedes the building permit.

Then it goes further, and this is the unusual part: “The health department may also set a minimum lot size larger than that required by this ordinance.”

Read that carefully. In most Georgia counties, the zoning table gives you a minimum lot size and that is the number — the health department works within it. In Upson County the zoning minimum is a floor, not a ceiling. After a site study, Environmental Health can require more land than zoning would.

Two practical consequences:

• Checking the zoning table is not sufficient due diligence in Upson County. A parcel that satisfies zoning on paper can still be refused, or required to be larger, on the basis of what the site study finds.
• The soil study is not merely a technical formality — it can change the required lot size. That makes commissioning it early more important here than almost anywhere else in the district, because an unfavorable finding does not just mean a bigger drain field, it can mean the lot is inadequate.

If you are buying land in Upson County, the question to ask Environmental Health before you commit is not “does this meet the minimum lot size” but “has a site study been done, and what lot size would you require here?”

A Sewered Center and a Septic-Dependent Remainder

The 2020 Census recorded Upson at 53.3 percent urban and 46.7 percent rural — the most urbanized of the smaller District 4 counties, and a genuine split rather than a rural county with a town in it.

That produces two quite different realities inside one county. Thomaston is sewered. The unincorporated remainder, draining toward the Flint, is septic-dependent. Advice that suits one does not suit the other, and the mandatory sewer-connection rule engages for properties near the Thomaston network while being irrelevant a few miles out.

So the first question in Upson is which of those two counties you are actually in. Ask about sewer availability at your specific address before assuming either answer.

Replacing an Old Drain Field: There Is No Grandfather Clause

This is the fact that costs Georgia homeowners the most money, and almost nobody hears it up front.

Under Ga. Comp. R. & Regs. 511-3-1-.03(2)(c), repairs, replacements and additions to existing systems must be permitted and inspected. And 511-3-1-.03(1)(b) lets a failing residential system under 2,000 gallons per day avoid forced sewer connection only “if the repair or replacement of the system will meet the criteria set forth in the Manual” — today’s Manual, not the one in force when the system went in.

There is no reduced-criteria table for repairs. A field installed decades ago to the standards of its day gets re-sized to current standards. In practice that means a larger field, relocation to another part of the lot, or an alternative engineered system where conventional design will not fit.

Upson adds a specific risk to repairs: if Environmental Health can require a larger lot size than zoning after a site study, then a replacement field on a small older lot may run into a requirement the original system never faced. Ask what your lot supports under current practice before you commission work. See our Georgia septic repair cost breakdown, and the financial assistance routes that exist in Georgia.

Soil Reports, Not Perc Tests

Georgia does not use percolation tests. Permits are decided on a Level 3 soil classification report prepared by a Georgia DPH-certified soil classifier, who must carry $1,000,000 in liability insurance. If a contractor offers to run a perc test on your Upson County lot, they are describing a procedure the state does not accept.

What a New Residential Application Requires

District 4’s forms are district-wide — one version naming all twelve counties. The New Residential and Residential Repair forms were last revised August 12, 2024; the commercial forms September 6, 2024.

A new residential application needs a lot sketch showing dimensions, the building footprint with setbacks, the road name, well locations on your property and on adjacent properties, driveway and paved surfaces, underground utilities, the plumbing stub-out, the proposed drain field location, easements, floodplain, and any detached structures.

Two clocks. The county board of health “shall approve or disapprove such application within twenty days after the receipt of a completed application” (511-3-1-.03) — and the words that matter are completed application. An issued permit expires 12 months from issue. Notify Environmental Health before final cover; an inspection they were not given the chance to make is a system they will not sign off.

Statewide Rules That Apply in Upson

None of this is local to Upson — it comes from DPH Chapter 511-3-1, covered in full on our Georgia septic regulations page. These are simply the provisions Upson applicants hit most often.

• A permit is required before you “begin the physical development of a lot or structure.”
• Only DPH-certified contractors may perform the work.
• Minimum tank size 1,000 gallons; two-compartment with an effluent filter for anything installed after February 20, 2000.
• Setbacks: 50 feet tank to well, 100 feet absorption field to well, and not less than 50 feet from the normal water level of any impoundment, stream or ponded wetland.
• Sewer connection is mandated where public or community sewer is available within 200 feet of the property line. With the county over half urban, this applies to a meaningful share of Upson properties — more than in most of District 4.
• Georgia requires no point-of-sale septic inspection anywhere in the state. Nobody will make you look at the system on a Upson County house you are buying. Look anyway.

What We Could Not Confirm

Where Upson Sits

Thomaston anchors a county about halfway between Atlanta and Columbus, sewered at its center and septic-dependent around its edges, draining toward the Flint. For the wider picture see our Atlanta metro septic guide, and its District 4 neighbors Lamar and Pike, where lot-size rules are documented very differently.

All twelve District 4 counties, and what differs between them, are compared on our District 4 septic permits page.
