Do you need a building permit in Rockdale County, Georgia?
Yes. Rockdale County requires a permit for new construction, reconstruction, alteration, repair or demolition of a structure, and electrical, mechanical and plumbing work may also require permits1. New construction and major renovation permits operate as master permits, so separate permits for every covered activity are not required1. Georgia's mandatory construction codes apply to construction in Rockdale County whether or not each code is locally enforced11. An owner building the owner's own home may qualify for Georgia's contractor-license exemption, but the owner must still comply with local building codes and regulations12. Residential construction covered by Rockdale County's rule must receive a certificate of occupancy showing that the building, lot and occupancy comply with the building code and county land-use rules13.
Who is the Rockdale County building department, and how do you reach them?
Rockdale County Planning & Development is the starting point for county building applications at 1117 West Avenue SW, Conyers, GA 30012, phone (770) 278-71002. A residential application needs a structure-location plan, and an applicable land-disturbance permit must precede the building permit14. The fee schedule revised in 2025 calculates residential building permit fees using the current ICC Building Valuation Table: construction cost multiplied by 0.0065, with a $100 minimum7. Ask Planning & Development to confirm the valuation and total charges for your project7. Rockdale County Code Enforcement is the contact for existing violations or complaints at 2570 Old Covington Highway, Conyers, GA 30012, phone 770-278-710315.
Does Rockdale County have zoning?
Rockdale County’s Unified Development Ordinance applies throughout unincorporated Rockdale County; uses must conform to the ordinance, and incorporated municipalities may administer separate rules3. Planning & Development maintains the official zoning map, with districts including AR, PV, CRS and R-116. Ask Planning & Development to identify the parcel’s district and confirm allowed uses, setbacks and siting standards before choosing a house design1617. In Rockdale County’s CRS collaborative residential subdivision district, dwelling units must have at least 1,800 square feet of heated floor area; that requirement is district-specific9. We could not confirm a complete accessory-dwelling or local manufactured-home occupancy rule; ask Planning & Development about the proposed use2.
How do septic permits work in Rockdale County?
Rockdale Environmental Health, a state-run agency that partners with the county, issues permits and inspects onsite sewage systems in Rockdale County18. Reach the office at 1329 Portman Drive, Suite F, Conyers, GA 30094, phone 770.278.734019. A residential permit application for a property using septic must include an Environmental Health approval letter; a property using sewer must instead provide proof of connection45. The site must be found suitable before an onsite sewage construction permit is issued, and the permit remains valid for no more than 12 months20. Environmental Health must complete the final inspection and give written approval before the system is backfilled or used21. About 77% of Rockdale County soils are rated “not limited” for a conventional drain field, but the lot still needs individual approval2220.
Can you live in an RV or tiny home on your land in Rockdale County?
In Rockdale County residential districts, an RV must be parked in a garage, carport, back yard or side yard, never the front yard, and must have current tags and registration23. Those parking restrictions do not establish permission to live in an RV; we could not confirm residential RV occupancy or temporary-camping rules, so ask Planning & Development before using an RV as housing232. Site-built and modular tiny homes in Georgia need applicable building-code compliance and local siting approval24. Rockdale County’s CRS district requires at least 1,800 square feet of heated dwelling floor area, so confirm the district before planning a tiny home916. Manufactured homes require a state installation permit obtained by a licensed installer, plus applicable local zoning and siting approval8.
How do you build a home in Rockdale County, step by step?
- Ask Planning & Development to confirm the zoning district and applicable siting rules, then prepare the required structure-location plan1614.
- Obtain an Environmental Health approval letter for septic or proof of sewer connection, and obtain the required water-meter receipt5.
- If applicable, secure the land-disturbance permit before building-permit approval14.
- Submit the house plans and structure-location plan for zoning and plan review; after approval and the required erosion-and-sediment-control inspection, the building permit may be issued14.
- If the site is in a floodplain, provide the flood-elevation certificate before the framing inspection can be approved25.
- Complete the required building and septic inspections; Environmental Health must approve the septic system before backfilling or use21.
- Obtain the required certificate of occupancy before occupying the completed residence13.
What should you check before buying land in Rockdale County?
Ask Planning & Development to verify the zoning district and proposed use before making an offer162. For a septic lot, obtain Environmental Health's view of site suitability rather than treating the countywide soil figure as approval for an individual parcel2022. A residential structure-location plan must identify the 100-year floodplain, wetlands, streams and applicable buffers or special setbacks, and a flood-elevation certificate can hold up framing approval on affected sites25. Ask Stormwater Management about drainage and floodplain conditions26. We could not confirm a countywide private-well permit rule, so ask Environmental Health before drilling19. Confirm county-road access with the Department of Transportation; the countywide driveway rule remains unconfirmed27. Rockdale County's effective property-tax rate is about 0.7%, and the median annual bill is about $1,8431028.
Watch-outs
- The county Unified Development Ordinance applies to unincorporated Rockdale County; confirm the parcel’s municipal boundary before relying on county zoning guidance3.
- A floodplain-affected project cannot receive framing-inspection approval until the department receives a flood-elevation certificate25.
- Rockdale County’s residential RV parking rule does not confirm permission to live in an RV or camp temporarily; ask Planning & Development before using an RV as housing232.
