Gwinnett County, Georgia
Gwinnett County is Georgia's second-most-populous county, a sprawling, highly diverse Atlanta suburb running from the I-85 corporate corridor around Duluth and Peachtree Corners east to the county seat of Lawrenceville. Decades of steady growth have left it largely built out, so infill, teardown-rebuilds, and redevelopment along aging commercial strips now drive more activity than raw greenfield expansion.
