Zoning, building permits and septic rules in Cumming, Georgia

Inside the city limits of Cumming, Georgia, a building permit is required before a building is erected, moved, extended or structurally altered1. The city's Planning & Zoning Department handles building permits and Cumming's own zoning23. Septic permits stay with Forsyth County Environmental Health4, and only where no public sewer is available5.

Does Cumming, GA have zoning, and what does it mean for RVs, tiny homes and lot size?

Yes. The City of Cumming has its own zoning, found in Chapter 113 of the Cumming Code and administered with a board of zoning appeals3. Districts referenced in the code include R-3, CBD and INST, and we have not confirmed the full district list11.

Outside RV parks or commercial storage, an RV inside Cumming may be parked or stored only in side yards, rear yards, carports or an enclosed building7. RV parks are a conditional use in Cumming7. The rules we reviewed do not address living in an RV on a residential lot, so ask the Planning & Zoning Department before you plan on it.

Every dwelling in Cumming must have at least 500 square feet of floor area for the first occupant, and the district's own minimum also applies8. A very small tiny home may therefore not qualify. Georgia treats tiny homes as ordinary dwellings under the building codes, and local zoning decides where they can sit12. We could not confirm lot-size or setback figures for Cumming's districts; ask the Planning & Zoning Department2.

Do you need a building permit in Cumming, GA, and who issues it?

Yes. Inside Cumming, no building may be erected, moved, extended, enlarged or structurally altered, and no lot may be excavated or filled for construction, until the building official has issued a building permit1. All building permits are issued by the building official6. The City of Cumming Planning & Zoning Department, not Forsyth County, is the office to call for building permits, inspections and certificates of occupancy inside the city2.

A permit expires 18 months after it is issued1. A city permit and a Forsyth County permit are separate: the county's Department of Building & Licensing covers unincorporated land, which is a different office13.

Georgia does not require a license to build your own home, but that does not waive local permits, inspections or zoning9. We could not confirm whether Cumming has an owner-builder permit process of its own; ask the Planning & Zoning Department.

How do septic permits work inside Cumming, GA?

Inside Cumming, a privy, septic tank or cesspool is unlawful except where no public sewer is available and the health officer approves it5. Where a public sewer lies within 100 feet of the property line, a building used for human occupancy must connect within 30 days after official notice14.

When septic is allowed, the permit does not come from the city. The Forsyth County Environmental Health Land Use Section issues on-site sewage permits and does the final inspection of systems4. Georgia requires a county board of health construction permit before a system is built, and the board must inspect before the system is backfilled or used1516. An applicant who plans to build a home on septic needs approval from Environmental Health before getting a building permit4. The county's septic stats are county-level: about 52% of Forsyth County soils are rated not limited for a conventional drain field17, so a site evaluation still matters on any given lot.

Building a home in Cumming, GA: the steps, in order

  1. Confirm the lot's zoning district and whether sewer is available with the Planning & Zoning Department2.
  2. If a public sewer is not available, get approval from Forsyth County Environmental Health before applying for the building permit4.
  3. If the lot was created in a recent subdivision, make sure the final plat is approved and recorded, because no building permit issues without it18.
  4. Check floodplain status; new residential buildings next to the future-conditions floodplain have special lowest-floor requirements10.
  5. Submit plans and obtain the building permit from the building official6.
  6. Call for inspections at least a day ahead and keep the permit card posted on site2.

What stays with Forsyth County, and what to check before you buy in Cumming

Cumming is in Forsyth County. The city's rules cover land inside the city limits only; land outside is covered by Forsyth County's page and the county's own rules. Septic permits for any address in Forsyth County, city or not, come from county Environmental Health4.

For cost context, Forsyth County's effective property tax rate is 0.8%, with a median bill of $3,747 a year1920. Forsyth County is dense, with about 1,215 people per square mile21, so expect a suburban setting rather than rural land. Georgia also allows a conservation-use property tax assessment for qualifying farm or timber land, which is a tax benefit and not a zoning exemption22.

Watch-outs

  • For rezoning, variances or conditional uses inside Cumming, ask the city's Planning & Zoning Department2.
  • We could not confirm Cumming's lot-size, setback or height rules, permit fees, tiny-home treatment or well rules; call the Planning & Zoning Department or Forsyth County Environmental Health24.
  • Georgia's driveway permit for a state highway right-of-way applies where a driveway meets a state route, even inside a city; residential driveway applications go to the GDOT District area office23.
