What did the new Alpharetta outdoor dining law change?

The exact wording of that ordinance change is not something to take on faith without checking Alpharetta's own code directly, since a secondhand summary can easily get the details wrong. Georgia cities that adjusted outdoor dining rules after temporary pandemic-era allowances generally either made permanent permitting available, restricted hours or footprint, or reverted to pre-pandemic rules entirely, with real variation between cities. Alpharetta's own city code, published on its official site, is the reliable source for current rules. Joel Boss can point you to Alpharetta's planning or code enforcement office.
