# Jurisdictions

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.

Unincorporated Gwinnett is derived geometrically — the county boundary minus the union of all
17 cities — so the resolver can name it affirmatively rather than by elimination.

Cross-county municipalities — Braselton (4 counties), Auburn, Loganville and Rest Haven (2
each) — report their full incorporated area, not just the share inside Gwinnett, so these
figures do not sum to the county total.
