Do you need a building permit in DeKalb County, Georgia?

Unincorporated DeKalb County requires building permit applications for residential construction, including single-family homes and duplexes1. The county inspects work through final inspection for compliance with approved plans and codes, and adopted the 2024 ICC codes effective January 1, 20261617. The portion of Atlanta extending into DeKalb County uses Atlanta’s building permits; DeKalb Public Health Environmental Health still handles septic systems countywide185.

DeKalb’s homeowner route requires a Homeowner’s Affidavit and does not waive building permits or inspections10. The applicant must already own and occupy the primary residence and directly supervise work not performed by licensed contractors; electrical, plumbing, heating and air-conditioning work needs separate applications9. Required inspections must follow the established sequence, or noncompliant work may be ordered removed9.

Who is the DeKalb County building department, and how do you reach it?

DeKalb County’s Permits, Plan Review & Inspections Division is the building department for county-handled projects19. The office is at 178 Sams Street, Decatur, GA; call 404-371-2155 or email permitinfo@dekalbcountyga.gov19. Submit plans and required documents through ProjectDox; applicable disciplines review them, the applicant responds to comments when needed, and approval leads to permit issuance20. DeKalb publishes a fee schedule; the detailed schedule lists a minimum building-permit fee of $175 plus a $20 technology fee2122. For parcel use, rezoning, a variance or a special land use permit, contact the Zoning Division separately at the same street address14.

Does DeKalb County have zoning?

DeKalb County’s zoning ordinance governs development in unincorporated DeKalb County2. The portion of Atlanta extending into DeKalb County uses Atlanta’s zoning districts; septic systems remain with DeKalb Public Health Environmental Health countywide235. The county publishes district, overlay, use, site-design and building-form regulations, with property-specific district information available through county maps247. Ask the Zoning Division to confirm the proposed dwelling type, use, setbacks and parcel-specific approvals before purchase14. We could not confirm DeKalb-specific accessory-dwelling or minimum-home-size rules, so ask the Zoning Division about those too14.

How do septic permits work in DeKalb County?

DeKalb Public Health Environmental Health handles on-site sewage systems countywide25. Obtain the construction permit before physically developing a lot that will use septic; the County Board of Health must decide a completed application within 20 days, and an issued permit remains valid for no more than 12 months26. A certified contractor must obtain approval before installing a new system or drain line or repairing a system, using the construction-permit application and engineered-site-plan checklist8. A certified contractor does not need a permit merely to pump out an existing septic tank27. Applications may be emailed to dekalb.eh@dph.ga.gov or delivered to 445 Winn Way, Suite 320, Decatur, GA 30030828. The system cannot be backfilled or used until final inspection and written approval29. About 51.4% of county soils lack severe limitations for a conventional drain field, so obtain a parcel-specific site evaluation before budgeting for a standard system30.

Can you live in an RV or tiny home in DeKalb County?

In unincorporated DeKalb County, campground operators must limit camper stays to no more than 15 days within a two-month period, and campground zoning rules also apply13. We could not confirm a general rule for long-term RV occupancy or temporary camping on private land outside a campground, so ask the Zoning Division about the parcel and proposed use14. A site-built or modular tiny home used as a dwelling needs applicable Georgia building-code compliance and local siting approval11. If a tiny home is legally a mobile or manufactured home, its use outside a mobile-home zoning district is limited to housing caretakers or security personnel, and it cannot be used commercially12. A licensed installer must also obtain the state installation permit for a manufactured home, while local zoning, siting and utility rules still apply15.

How do you build a home in DeKalb County, step by step?

  1. Confirm whether the parcel is in unincorporated DeKalb County or an incorporated city, because the city may be the primary permit authority3.
  2. Confirm the zoning district, overlay and proposed residential use with the Zoning Division714.
  3. Before splitting, recombining or consolidating land, complete county subdivision and plat review; approved plats must be recorded, and land disturbance may need its own permit3132.
  4. If the home will use septic, secure Environmental Health approval before site development or installation begins8.
  5. If the home will use public sewer instead, complete the county’s Sewer Capacity Evaluation33.
  6. Submit plans through ProjectDox, respond to review comments, obtain the permit and complete inspections2016.
  7. For projects requiring a certificate of occupancy, obtain it from DeKalb Development Services after all required inspections pass; the listed fee is $50, and temporary certificates are non-residential only34.

What should you check before buying land in DeKalb County?

Start with jurisdiction and zoning: confirm whether the tract is unincorporated and identify its district and overlay37. If you may divide or recombine the tract, DeKalb reviews subdivisions and plats against zoning, design and engineering standards32. DeKalb projects in flood hazard areas must meet FEMA and local standards, including structures, fill, utilities, subdivisions and site improvements; ask Floodplain Management for a parcel-specific determination3536. Utility work, construction and lane closures in a county right-of-way require a right-of-way encroachment permit37. For septic land, verify soil and site suitability; only 51.4% of county soils lack severe conventional drain-field limitations30. For a well, Georgia requires advance contact with the county health department, but we could not confirm that DeKalb requires a separate construction permit38. Also ask the appropriate road authority about driveway approval; a driveway in a state-highway right-of-way requires GDOT approval39.

Watch-outs

  • A DeKalb mailing address does not prove county jurisdiction; incorporated cities may be the primary permitting authority, so check the parcel before applying3.
  • We could not confirm long-term RV occupancy or temporary-camping rules for unincorporated DeKalb County; ask the Zoning Division about the exact parcel and use14.
  • A failed on-site sewage system must connect immediately to an available public or community sewer unless the stated county health criteria support an exemption33.

Georgia rules that apply here

  • Building code adoptedAdopted

    The Georgia mandatory state minimum construction codes, including the International Building Code, International Residential Code for One- and Two-Family Dwellings, International Fire Code, International Plumbing Code, International Mechanical Code, International Fuel Gas Code, National Electrical Code, International Energy Conservation Code, and International Swimming Pool and Spa Code, apply to construction statewide.

    • Any structure built in Georgia must comply with the mandatory codes whether or not the local government chooses to locally enforce them.
    • Local governments are not required to adopt the mandatory codes, but must adopt administrative procedures to enforce them under O.C.G.A. Section 8-2-25(a).
    • A local government may choose which mandatory codes it will locally enforce.
    • Local amendments cannot be less stringent than the state minimum code; must be based on local climatic, geologic, topographic, or public safety factors; must identify the need for more stringent requirements in legislative findings; and must be submitted to DCA 60 days before proposed adoption.
    • DCA has 60 days after submission to make a recommendation. If DCA recommends against adoption, the local governing body must specifically reject that recommendation before adopting and enforcing the amendment. If DCA does not respond within 60 days, the local government may adopt the amendment. Adopted local amendments must be filed with DCA.
    “As noted above, the building, one and two family dwelling residential, fire, plumbing, mechanical, gas, electrical, energy, and swimming pool codes are mandatory codes, meaning that under Georgia law, any structure built in Georgia must comply with these codes, whether or not the local government chooses to locally enforce these codes. In addition, since Georgia law gives the enumerated codes statewide applicability, it is not required that local governments have to adopt the mandatory codes.”
