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

Yes. Acworth, Georgia has its own zoning ordinance, published as Appendix B of the Acworth Code of Ordinances, and it applies to land inside city limits2. The city's Planning & Zoning division administers it6.

Districts set the numbers. In the R-3 single-family district the minimum lot is 9,000 sq ft7, with setbacks of 25 ft from an arterial street, 15 ft from other streets, 10 ft on an interior side and 20 ft in the rear11. In R-5, a detached single-family lot can be 6,000 sq ft8, with 5 ft interior and 10 ft rear setbacks12. Both districts cap height at 35 ft13 and impervious surface at 45%14.

RVs: people may live in a recreational vehicle only in the C-2 district, for no more than 14 days in any 30-day period, and an RV may not be parked on an R-zoned lot without a permanent dwelling4. We did not find a tiny-home rule for Acworth; ask Planning & Zoning at 770-974-20326.

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

Yes, building inside Acworth city limits runs through the City of Acworth Building Services, which administers and enforces the Georgia state minimum standard codes for buildings within the city1. The city enforces the state-adopted codes5.

Starting work without the required permit carries a penalty of 100 percent of the standard permit fee on top of the fees themselves1. Call Building Services at (770) 974-2032 or visit Acworth City Hall at 4415 Center Street1.

Georgia does not require you to hold a license to build your own home, but that exemption does not waive local codes, permits, inspections or zoning10. Cobb County's homeowner-permit program covers unincorporated land only15; we could not confirm how owner-builders are handled inside Acworth, so ask Building Services.

How do septic permits work in Acworth?

Septic permits are a county-level health matter, not a city one. Cobb & Douglas Public Health regulates septic tanks in Cobb County16, and any installation, repair or modification of a septic system needs a permit from that department before work starts3. Georgia rules also require a final inspection and written approval before a system is backfilled or used17.

The current residential inspection and permit fee is $2503. We could not confirm whether a given Acworth address is on public sewer; ask the City of Acworth and Cobb & Douglas Public Health before assuming you need a septic system.

Building a home in Acworth: the steps, in order

  1. Confirm the lot's zoning district and its lot-size, setback and impervious-surface limits with Planning & Zoning at 770-974-20326.
  2. Check whether any part of the lot is in the floodplain; new construction there must meet Acworth's floodplain standards, including a lowest floor at least 3 ft above base flood elevation or 1 ft above the future-conditions flood elevation, whichever is higher18.
  3. If you are subdividing, note that Acworth regulates subdivision of land and restricts developing low areas that flood periodically19.
  4. If the lot is not on public sewer, get a septic permit from Cobb & Douglas Public Health3.
  5. Apply for building permits through Acworth Building Services1.
  6. Pass the required inspections, then the septic final inspection if applicable17.

What stays with Cobb County, and what to check before you buy in Acworth?

Land outside Acworth city limits is under Cobb County, not the city. For unincorporated land, see the Cobb County page. Cobb County's zoning map covers unincorporated Cobb County only20, and septic permits for every Cobb address come from Cobb & Douglas Public Health16.

Before buying, confirm the lot's zoning district, floodplain status, and sewer availability. Cobb County's effective property tax rate is 0.7%21 and the median property tax bill is $2,560 a year22. These are county-wide figures, not Acworth-only.

Watch-outs

  • Only the R-3 and R-5 district text was reviewed for Acworth; other districts such as C-2 and OP exist, so verify the zoning for any specific lot with Planning & Zoning23.
  • We could not confirm Acworth's building permit fees, certificates of occupancy or inspection details; ask Building Services at (770) 974-20321.
  • Camping in Acworth city parks and on public streets is prohibited, and camping on private land follows the RV rule above24.
