Does Avondale Estates, Georgia have zoning, and what does it mean for lots and setbacks?

Yes. The City of Avondale Estates divides the land inside its city limits into zoning districts under its own code of ordinances1. The residential districts are R-12, R-24 and MFR9. The city requires zoning approval for all residential and commercial development projects10.

In the R-12 district the minimum lot area is 12,000 square feet5. In the R-24 district it is 24,000 square feet6. Maximum lot coverage is 40% in R-12 and 30% in R-247. Primary buildings need a 40-foot front yard in both districts, with interior side yards of 10 feet in R-12 and 20 feet in R-24, and rear yards of 35 feet and 40 feet11. Principal buildings are limited to 35 feet and accessory buildings to 24 feet12.

The city's zoning code covers commercial districts and the central business district too, but we did not confirm their standards, so check Avondale Estates Planning & Permitting before buying in those areas9.

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

Inside Avondale Estates, the city issues building permits itself: Avondale Estates manages all building permits and inspections through the Community Core online portal2. The DeKalb County building permit rules apply to unincorporated land, not to addresses inside the city13.

The city's page lists separate land disturbance permits for projects that disturb more than 1,000 square feet of land or add more than 1,000 square feet of impervious surface2. The first round of plan review takes about 10 business days2.

Georgia does not require a state license to build your own home, but the owner still has to follow local building codes, permits and inspections8. We could not confirm whether Avondale Estates has its own owner-builder procedure or what its building permit fees are; ask the city's Planning & Permitting office2.

How do septic permits work inside Avondale Estates?

Septic permits do not come from the city. DeKalb Public Health Environmental Health approves and issues septic permits in DeKalb County14, and a new septic system, new drain line or repair must be permitted before a contractor starts work3.

Georgia law requires a connection to public or community sewer when one is available within 200 feet of the property line15. We could not confirm whether a given Avondale Estates address is sewered, so ask the city before assuming a septic system is an option. Well permits inside the city are also unconfirmed; Georgia has certain county health departments that require them16.

Can you live in an RV or tiny home in Avondale Estates?

Only in a narrow case. Avondale Estates allows an RV to be occupied for human habitation only in the O-I district, for a maximum of 14 days in any 30-day period4. The city's code also bars parking an RV on an R-zoned lot that has no permanent dwelling4. On R-zoned lots, RV parking is prohibited in the front or street side yard4.

We could not confirm the city's rule for tiny homes. Georgia treats a site-built or modular tiny home like any other dwelling under the building codes, and local zoning decides where it can be sited17. Ask Planning & Permitting before buying.

How do you build a home in Avondale Estates, step by step?

  1. Confirm the lot's zoning district (R-12, R-24 or MFR) and its lot size and setbacks9.
  2. Check whether the lot touches a floodplain: new construction is not allowed in the future-conditions floodplain unless the city's flood requirements are met18.
  3. Apply for the permit in the Community Core portal and upload files for zoning, land disturbance and building plan review2.
  4. Allow roughly 10 business days for the first round of plan review2.
  5. If the home will use septic, get the septic permit from DeKalb Public Health before work begins3.
  6. Request inspections through the portal and ask for a certificate of occupancy when they pass2.

What stays with DeKalb County, and what should you check before buying in Avondale Estates?

Septic permits, and the county health office's role in wells, stay with DeKalb County rather than the city19. Land outside city limits follows DeKalb County's rules instead; see the DeKalb County page for unincorporated land.

DeKalb County's typical home value is about $339,25920 and its effective property tax rate is 0.9%21. Across DeKalb County, about 51.4% of soils rate as not limited for a conventional septic drain field22.

Watch-outs

  • We could not confirm the city's rules on tiny homes, accessory dwelling units, minimum home size, subdivision or building permit fees; ask Avondale Estates Planning & Permitting2.
  • Properties in the historic district may need a certificate of appropriateness from the Historic Preservation Commission before a building permit can be issued2.
  • Fences, driveways, plumbing and HVAC systems each need their own permits in Avondale Estates2.
