New Home Construction · DeKalb County, Georgia
Permit required
In Georgia, a New Home Construction requires a building permit.
Building a new home always requires a building permit, plus separate electrical, plumbing, and mechanical permits and full plan review. Zoning, setback, and impact-fee review also apply. Plans are reviewed under the Statewide code (IRC 2024); apply through Planning-Comprehensive Plans before work begins.

Building a custom home from the ground up requires comprehensive oversight from the city. This involves a master building permit that encompasses zoning, foundation, framing, plumbing, electrical, and HVAC. It is the most heavily regulated residential project, ensuring the dwelling is safe for human habitation.
Given that DeKalb County has a densely packed population of 765,351 residents, the local building department frequently experiences high application volumes. Expect processing times of 4 to 8 weeks for standard residential projects.
Code Compliance & Inspections
Because Georgia sits in a hurricane-prone zone, the Georgia State Minimum Standard Codes requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
HOA & Historic District Approvals
In highly urbanized counties like DeKalb County, municipal bureaucracy is only the first step. You will almost certainly need written approval from your Homeowners Association (HOA) before applying for a city permit. Additionally, if you live in a designated historic district, the local architectural committee holds veto power over your New Home Construction.
Zoning & Cost Factors
Georgia mandates adherence to state minimum standard codes, but allows local governments significant flexibility in enforcing aesthetic and density zoning ordinances. Fortunately, Georgia maintains relatively builder-friendly regulations, keeping base permit fees competitive.
Estimated municipal base fee: $1,275–$1,950
This is a planning estimate only — actual fees in DeKalb County depend on your project valuation. A typical breakdown looks roughly like:

Always confirm exact fees with your local building department before applying.
