You must obtain a building permit from the local planning and zoning department to build an ADU in Georgia. The permitting process may vary depending on the city or county where you plan to build your ADU, but here are some general steps and Georgia ADU laws to follow.

  • Understand the regulations: Review the ADU rules for your zoning district and lot size. Ensure your ADU design meets the location, size, bedrooms, and impervious surfaces standards.
  • Prepare a site plan: Create a plan showing the ADU's dimensions, location, setbacks, parking, utilities, and landscaping.
  • Submit your plan: Take your site plan and ADU design to the planning and zoning department for review. Pay the fee and include additional documents like floor plans and engineering drawings.
  • Obtain the building permit: Once your plan is approved, apply for the building permit. Pay the fee and provide the necessary information, such as insurance and contractor license.
  • Begin construction: With the permit in hand, start building your ADU—schedule inspections to ensure compliance with building codes and regulations.
  • Obtain the certificate of occupancy: Once construction is complete, get a certificate of occupancy from the building department. This certifies that your ADU is safe for use.
