# Duluth UDC Table 2-B

Area Regulations by Zoning District

**Governing jurisdiction: Duluth.** A "Duluth, GA" mailing address is usually NOT in the City of Duluth. Unincorporated Gwinnett is 67.3% of the county's land area and is governed by a different code, a different board and a different permit portal. Resolve the governing jurisdiction before answering any zoning question.
