Homeowners in Cumming and across Forsyth County ask the same question at the start of almost every project: does this need a permit? It depends on the work, and Forsyth County publishes a reasonably clear guide to which side of the line a job falls on. What follows is the county's own process, in the order you actually encounter it. Requirements change, and nothing here replaces confirming your specific project with the county before work begins.
Who issues permits, and where you apply
Residential building permits come from the Forsyth County Department of Building and Licensing, Permitting Division — in the county's words, "The Permitting Division issues all building permits." The office is at 2435 Freedom Parkway, Suite 1100, Cumming, GA 30041; the permitting number is (770) 781-2114.
Applications go through the county's Customer Self-Service (CSS) portal at css.forsythco.com. For an addition, the county's packet says applications "may be submitted electronically through the Customer Service Portal or in person at our office." For a brand-new house there is no paper path: "Applications for new residential dwellings must be submitted electronically through the Customer Service Portal."
The county publishes a separate packet per permit type — addition, basement finish, new dwelling, renovation, deck/porch, accessory structure, pool, retaining wall, townhome or condominium — and the checklists differ. Pulling the right packet first saves a rejected submittal.
What needs a permit, and what does not
This is where general home-improvement advice is often simply wrong for Forsyth County. The county's "Do I Need a Permit?" guide carries its own caveat — it "is provided as a guide to assist homeowners and contractors; it does not include every type of permit required" — but it is specific.
Permit required, per that guide: interior additions and interior remodels; basement finishes; accessory structures; deck construction or repair; retaining walls over 6 feet, measured from the bottom of the footing to the top of the wall; single-family dwellings on monolithic slab or basement foundation; swimming pools and spas; adding or replacing a plumbing fixture where piping is altered; irrigation; water heater replacement; adding an electrical circuit or repairing/upgrading electrical service; furnace or AC replacement.
Permit not required: painting, tiling, carpeting and trim work; roofing, re-roofing and shingle replacement; siding replacement; retaining walls 6 feet or less; non-structural deck repairs such as replacing floor boards or repairing guards on decks less than 30 inches above grade; garage door repair or replacement; ductwork replacement; fixture repair or replacement with no piping alterations; appliance replacement using plug-in devices.
Two things surprise people. Roofing and siding replacement do not require a permit here, contrary to a lot of national guidance. And the trigger for plumbing is whether piping is altered, not whether a fixture is touched. There is also an emergency carve-out for water heater and HVAC replacement: "Emergency repairs need not obtain a permit prior to performing repair/replacement. Permit and inspection should occur as soon as possible after repair/replacement."
If you are on septic, that approval comes first
This is the sequencing detail that derails Forsyth County projects. The county's Environmental Health Land Use Section states it plainly: "If you plan to build or remodel a home or if you want to put a building or pool on your property that is served by a septic system you will have to get approval from the environmental health department before you can obtain a building permit."
Environmental Health also warns that "it may take twenty business days or more to process an application or review," and it publishes a dedicated Remodel or Addition Application for exactly this case. The office is at 2435 Freedom Parkway, Suite 2400, Cumming; 770-781-6909.
Read that order carefully: septic approval, then building permit. The addition packet lists "Environmental Health Approval — Required if on septic" as a required attachment, so the building application is incomplete without it. If your schedule assumes the two run in parallel, rebuild the schedule. A new dwelling on public sewer instead shows proof of sewer purchase and proof of water meter purchase, or a Well Affidavit.
What goes into the application
For a residential addition the checklist includes a Permit Details Form; an Authorized Agent Form for the general contractor with current business license and a copy of the state license, notarized; sub-contractor affidavits for electrical, mechanical and plumbing as needed; a scaled site plan; a copy of the approved recorded plat; Environmental Health approval if on septic; a temporary toilet permit if there is no toilet on site; and fees. If the homeowner pulls the permit, a notarized Owner/Contractor Self-Work Affidavit replaces the contractor forms.
A new dwelling adds floor plans for each level, elevation drawings, proof of sewer or septic, proof of water meter purchase, a Lot Grading Plan approved and stamped by the Engineering Department where applicable, and impact fees — "Impact Fees are required on all new residential dwellings."
The site plan is where submittals stall
The site plan asks for more than most homeowners expect: property lines with dimensions, abutting streets and rights of way, setback lines with dimensions, outlines of all proposed and existing structures including projections, driveways and walkways and pools and retaining walls, roof overhang outlines and dimensions, and the "location and dimension of all floodplain limits, buffer requirements, and all drainage or any other easements." Two specifics catch people: overhangs "cannot encroach into easements or buffers," and the packet states vinyl exterior material of any kind is prohibited in major subdivisions.
Setbacks stay your responsibility
Do not read an issued permit as sign-off on where the building sits. The county is direct: "The issuance of a building permit does not assure that the building setbacks have been met or that the structure does not encroach on any easement, or buffer. The owner and/or permit holder have the sole responsibility of determining compliance with setbacks." That is the argument for a current survey and an accurate plat before design gets far.
Disturbed acreage and erosion certification
The addition form asks for "total disturbed acreage associated with this permit and the disturbed acreage for any adjacent permits that will be disturbed at the same time," and states that if the disturbed acreage requires an individual lot permit, a Georgia Erosion and Sediment Control Certification Card is required at the time of permit.
That connects to state law. Georgia's Erosion and Sedimentation Act exempts projects disturbing less than one acre — but not disturbance within a larger common plan of development of an acre or more, "or within 200 feet of the bank of any state waters." Georgia also establishes a 25-foot buffer along the banks of all state waters. And even where an exemption applies, anyone responsible for land disturbance "must prevent sediment from moving beyond the boundaries of the property." Locally, Forsyth County's Stormwater Division enforces the county's Erosion and Sediment Control Ordinance. If a creek runs through or near the lot, erosion control is a design input, not a formality.
The inspection sequence
The county publishes its residential inspection types, and the list tracks the order of construction: Plumbing Underground; Footing; Monolithic Slab; Slab; Foundation Wall; Rebar Ground; Setback; Combination Rough Inspection; Rough Mechanical/Gas; Rough Electrical; Rough Plumbing; Rough Framing; Insulation; Temp to Perm; Fire Wall/Barrier for townhomes; Deck Setback; Deck Footing; Combination Final Inspection; Final Mechanical; Final Electrical; Final Plumbing; Final Building.
Two definitions are worth reading closely. Footing covers "depth, bearing strength of soil, any reinforcement required" — which matters on Piedmont lots, where the material a footing bears on is frequently subsoil clay rather than topsoil. For rough framing, the structure "should be dried in and weather protected," with a blunt instruction attached: "Nothing is to be covered without County approval." That is the line that costs money when ignored — insulation or drywall ahead of an approved rough means opening the wall back up. The county also notes that smoke alarms and carbon monoxide alarms are required and will be inspected and tested.
What a failed inspection costs
The consequences are published and specific:
- Reinspection fee. "A trade violation fee in the amount of $25.00 shall be charged for the first inspection and shall increase in increments of $25.00 for each subsequently failed inspection for the same inspection type." It escalates per failure, per inspection type.
- No power. "Power cannot be released without approved inspection."
- No final until fees clear. "Final Inspections cannot be requested until all outstanding fees are paid."
- Stop work orders. "A stop work order may be given for violations of codes. No work is to commence until the conditions of the notice are fulfilled and/or the violations are resolved."
- No occupancy without a CO. "Occupancy is not permissible until all inspections and code requirements are met and a Certificate of Occupancy has been issued by Forsyth County."
The $25 is small. The schedule cost of a stop work order, a delayed power release or a re-opened wall is not.
Your permit expires in 12 months
The rule is flat: "All building permits expire 12 months from the date of issuance." For a phased project, a long lead-time custom order, or a renovation a homeowner means to stretch out, that clock is a real constraint. Pulling a permit before design and selections are settled can burn months of it before the first trade arrives.
Licensing gets checked at the permit counter
Georgia requires a current, valid residential or general contractor license to engage in residential contracting, issued through the State Licensing Board for Residential and Commercial General Contractors in the Secretary of State's office. The consequence matters to homeowners: under O.C.G.A. § 43-41-17(b), a contract for licensed work with a contractor who does not hold a license "shall be unenforceable in law or in equity by the unlicensed contractor," and "no lien or bond claim shall exist in favor of the unlicensed contractor." Forsyth County makes that practical — the notarized Authorized Agent Form requires a copy of the state license plus a current business license.
The statute does contain genuine exemptions, including repair work where the person discloses they are unlicensed and the work "does not affect the structural integrity of the real property," and an owner-builder path for a home you will occupy yourself, subject to a 24-month restriction on selling and full compliance with local permitting.
