Planning a project in Glynn County, GA.
Glynn County has its county seat in Brunswick and counted 84,499 residents in the 2020 Census. It includes Brunswick, St. Simons Island, Sea Island and Jekyll Island.
The county has 1 incorporated city — Brunswick. Cities can run their own zoning and building permits, while unincorporated properties are reviewed by Glynn County Planning and Zoning. We confirm the reviewing office for your exact address before drafting.
Site conditions such as drainage, floodplain, septic, driveway access and land disturbance can change the sheets you need. We check those items against the reviewing office's current checklist rather than assuming one county-wide list.

What we check for Glynn County projects.
A permit drawing set only works when it matches the property and the office that will review it.
Current Georgia codes
State minimum building, residential, electrical, plumbing, mechanical and energy codes in force, plus local amendments.
Zoning and setbacks
Zoning district, front, side and rear setbacks, height, lot coverage and accessory-structure rules.
Survey and parcel data
Plat or survey, county GIS parcel lines, easements, rights-of-way and existing improvements.
Drainage and land disturbance
Grading, runoff, erosion and sediment controls, and stream buffers where land is disturbed.
Special site approvals
Flood zones, coastal marshlands, septic, GDOT access and fire review when they apply.
Georgia requirements that can affect Glynn County drawings.
Building and residential codes
Georgia DCA publishes the State Minimum Standard Codes for Construction. Local building departments enforce them and can adopt qualifying local amendments that are stricter than the state minimum.
Local zoning and administration
Glynn County and each of its cities set their own zoning, permit procedures and inspections. Zoning controls use, setbacks, height, parking and lot coverage.
Erosion, sediment and stormwater
Land-disturbing work can require an erosion and sediment control plan and local land-disturbance approval. Larger construction sites can also need coverage under Georgia EPD's construction stormwater permit.
Streams, buffers and flood-prone sites
Georgia EPD protects a 25-foot vegetative buffer along most state waters. FEMA flood maps and local floodplain rules can add elevation and drainage requirements.
Coastal marshlands
Work in or next to tidal marsh can fall under Georgia's Coastal Marshlands Protection Act, reviewed by Georgia DNR's Coastal Resources Division, in addition to local permits.
Driveway access and septic
A new or changed driveway on a state route needs Georgia DOT access review. Properties without public sewer need environmental-health review and an on-site sewage permit through Glynn County Environmental Health.

Glynn County site plan questions.
Answers to what homeowners, builders and contractors ask before a Glynn County permit submission.
Who issues building permits in Glynn County, GA?
For unincorporated Glynn County, permits are handled by Glynn County Planning and Zoning. Incorporated cities such as Brunswick can run their own building and zoning offices, so the property address decides which office reviews your drawings.
Which building codes apply to Glynn County projects?
Georgia uses the State Minimum Standard Codes for Construction published by the Georgia Department of Community Affairs (DCA). Local governments enforce these codes and can adopt qualifying local amendments, so we confirm the current code set and the local checklist before drafting.
Do I need a site plan for a deck, shed, pool or addition in Glynn County?
Most permit applications for new structures, additions, pools and many accessory buildings ask for a site plan that shows property lines, the proposed work and setback distances. Smaller items can be exempt, so we check the reviewing office's current list for your address before quoting.
Can you prepare the site plan without a new survey?
Often, yes. Many plans start from an existing survey, recorded plat, GIS parcel data and your measurements. A licensed boundary survey is still needed when the reviewing office requires one, or when lot lines are uncertain or the work is close to a setback.
My Glynn County property uses a septic system. What changes?
Properties without public sewer usually need review by the Glynn County Environmental Health office (Georgia Department of Public Health) before a building permit for additions, pools or new buildings. The site plan should show the septic tank, drain field and required separation distances.
How do I know if my Glynn County lot is in a flood zone or stream buffer?
Check the FEMA Flood Map Service Center for the parcel. Work in a mapped flood zone can need elevation information and local floodplain approval, and work near streams can fall within Georgia EPD buffer rules. On the coast, work in or near coastal marshlands can also fall under the Coastal Marshlands Protection Act, administered by Georgia DNR's Coastal Resources Division.
How much does a Glynn County site plan cost and how long does it take?
Simple residential site plans start from $89. Larger lots, grading, drainage or full permit drawing sets are quoted by scope. You receive a written price and timeline before any drafting starts.
Can you help with Glynn County plan review comments?
Yes. Send the reviewer's comment letter and your current drawings. We identify which sheets need revision, quote the changes and prepare the resubmittal set.
