Gwinnett County, Georgia septic permits and requirements

Permitting authority

GNR Public Health — Gwinnett Environmental Health Department

Gwinnett Environmental Health: 770-963-5132; 455 Grayson Highway, Suite 600, Lawrenceville, GA 30046.

Georgia onsite-sewage framework

Georgia Department of Public Health regulates onsite sewage statewide while locally related permits, inspections, records and property-specific questions are handled through local County Environmental Health offices.

Gwinnett Environmental Health handles septic permitting and inspections

GNR Public Health identifies its Gwinnett Environmental Health office as the local Environmental Health department and publishes residential and commercial septic applications, repair and addition forms, inspection scheduling procedures, and land-use regulations. GNR states that Environmental Health involvement begins before a septic-served lot is created and continues until the property is connected to sewer.

A Level 3 soil report is required before septic permitting

GNR Public Health states that all of its Environmental Health departments require a Level 3 soil report before issuing septic permits for new systems, repairs, and additions that require modification of the existing septic system. Applicants should obtain the report from an appropriately qualified soil professional and submit the correct project-specific application.

New construction, repairs, additions, and existing-system evaluations have separate forms

GNR publishes separate residential applications for new construction, repair, and addition work, plus an existing septic system evaluation application. This distinction matters because a repair or building addition should not be treated as a new-system permit without Environmental Health review.

Current Gwinnett land-use fees are published

The Gwinnett Environmental Health fee schedule linked by GNR lists $275 for residential site evaluation, permit, and initial inspection; $600 for the commercial equivalent; $145 for a visual existing-system evaluation; $175 for reinspection; and double the applicable permit fee for installation without a permit. Confirm the live schedule before payment because fees may be amended.

Septic records and repair history can be researched

Gwinnett County states that Environmental Health maintains septic records dating to 1959. The county GIS Data Browser can show a septic-system sketch and, when available, past repair applications and permits, while copies of septic records can also be requested from Environmental Health.

Use Georgia-certified septic professionals

Georgia DPH maintains certification lists for septic installers, pumpers, and soil classifiers. GNR links those state resources from its septic page; verify current certification before hiring a contractor or soil professional.
