Gwinnett County does not set specific hours for garage sales but the county noise ordinance (Chapter 14) applies — no unreasonable noise before 7 AM or after 11 PM. Most sales run dawn-to-dusk by common practice.
Gwinnett County Code of Ordinances Chapter 14 (Offenses and Miscellaneous Provisions) addresses noise but does not establish dedicated garage-sale hours. The county noise ordinance prohibits loud and unreasonable sounds between 11 PM and 7 AM in residential zones, and PA systems/amplified announcements during sales fall under this restriction. Practical sale hours are dawn to dusk; most Gwinnett neighborhoods run 7 or 8 AM to 2-5 PM on Saturdays. The Georgia Department of Revenue does not regulate sale hours. Incorporated cities may set tighter hours — Snellville and Lawrenceville generally follow the same 7 AM-11 PM noise window. HOAs in large Gwinnett subdivisions (Sugarloaf Country Club, Hamilton Mill, River Club) frequently restrict sales to community-sponsored weekends and limit set-up/tear-down times. Signs placed in the public right-of-way (including utility poles) are prohibited at any hour under GA DOT rules and are removed by Gwinnett DOT without advance notice.
Noise violations before 7 AM or after 11 PM are citable under Gwinnett Code Chapter 14 with fines typically $100-$500 for first offense. Amplified sound without a permit can trigger additional penalties. Off-premises signs in the right-of-way are confiscated; repeated sign violations may result in $75-$150 per-sign fines under the UDO sign chapter.
