Review Process
All single-family residential projects require plan review by the city. The city’s review process may take up to 10 business days. If your project includes building a new home, it may also require review by DeKalb County (for elements such as water, sewer, health, or life safety). If you require review by DeKalb County, the city will provide you a routing sheet and directions to DeKalb County’s offices.

Fee Payment
We will email or call to let you know when the city’s plan review is finished. Once plans have been approved, you may pay your fees by Visa or MasterCard online or by check or cash at City Hall. The city will issue a permit for your project and provide your approved plans. To estimate your fees, you can review the Fee Schedule page.
