The Board of Commissioners amended the Code of Ordinances of Gwinnett County in fall 2023 by amending Title 1, Title 2, Title 3, and Appendix Sections 1.0 through 5.0, to add clarifying language, remove obsolete information, update regulations based on current and/or best practices, and more. This ordinance is set to go into effect on January 1, 2024.
