So, you're looking at a map of Georgia or maybe planning a move, and you find yourself wondering: what county is Peachtree City in?
It's in Fayette County.
Honestly, if you just wanted the quick answer, there it is. But if you stop there, you’re missing out on one of the weirdest, most interesting suburban experiments in the United States. This isn't just another "Atlanta suburb." It’s a master-planned world where 16-year-olds drive to high school in golf carts and the local grocery store has more cart parking than car spots.
The Fayette County Connection
Peachtree City is the heavyweight of Fayette County. While the county seat is technically Fayetteville, Peachtree City is the largest city in the area, sprawling across about 25 square miles of what used to be rural farmland.
Fayette itself was formed back in 1821. It was named after the Marquis de Lafayette—the French aristocrat who basically became a rockstar during the American Revolution. If you drive around the county today, you'll still see those historical nods, but Peachtree City feels significantly more "New South" than the surrounding towns like Tyrone or Brooks.

Why does this city even exist?
In the 1950s, a group of real estate developers (led by Pete Knox Jr. and Joel Cowan) had this wild idea. They wanted to build a "planned community" from scratch. They didn't want a grid of streets. They wanted "villages."
Today, those villages—Aberdeen, Braelinn, Glenloch, Kedron, and Wilksmoor—make up the backbone of the city. Each one has its own shopping center and its own vibe. It was designed so you’d never really have to leave your little bubble if you didn't want to.
Let's talk about the golf carts
You can't talk about Fayette County's crown jewel without mentioning the 10,000+ golf carts.
It sounds like a gimmick, but it’s a way of life. There are over 100 miles of multi-use paths weaving through the woods, over bridges, and under major highways (like SR 54 and SR 74).

- Who drives them? Almost everyone. Kids as young as 12 can drive them if a parent is in the front seat. By 15, with a permit, they're often solo.
- Where do they go? To the movies. To the Fred (the local Frederick Brown Jr. Amphitheater). To Starbucks.
- The Rules: You can't just go rogue. Carts have to be registered with the city. You need a registration decal, and if you're caught driving on the actual car roads instead of the paths, the local PD will definitely have a chat with you.
What's life like in 2026?
As of 2026, Peachtree City remains a high-income hub within Fayette County. Median household incomes here consistently hover well above $110,000, which is significantly higher than the Georgia average.
People move here for the schools—Fayette County schools are some of the highest-rated in the state—and for the safety. It’s the kind of place where people leave their garage doors open and kids play in the cul-de-sacs until the streetlights come on.
But it’s not all sunshine and golf cart parades.
The "Big Intersection" of Highway 54 and Highway 74 is a legendary nightmare for commuters. If you're trying to get through there at 5:15 PM on a Tuesday, God help you. Residents have been debating how to fix that traffic bottleneck for decades. It's the one part of the master plan that didn't quite account for just how popular the city would become.

A few things you might not know
People often think Peachtree City is just houses. It's actually a massive economic engine for Fayette County.
Major companies like Panasonic Automotive Systems, Hoshizaki America (they make the ice machines you see in hotels), and Cooper Lighting have huge footprints here. Even the National Weather Service has its primary Georgia office in Peachtree City.
And if you're a film nerd? You've probably seen the city on screen. Parts of The Walking Dead, Drop Dead Diva, and various Marvel movies have used the wooded paths and suburban streets of Fayette County as a backdrop.
Practical things for visitors
If you're visiting for a weekend, don't just stay in your car.
- Rent a cart: There are places near the hotels that will rent you a golf cart for the day. It’s the only way to actually "see" the city.
- Hit the Lakes: Lake Peachtree and Lake McIntosh are beautiful. You can't put a motorized boat on them (unless you're one of the few lucky homeowners with legacy rights), but they are perfect for paddleboarding or kayaking.
- The Night Market: If you're here during the summer, check out Drake Field. They often hold night markets and festivals right on the water.
So, there's your answer. Peachtree City is in Fayette County, but it’s also in a league of its own. It’s a bubble, sure, but it’s a remarkably well-designed one that has managed to stay relevant and wealthy long after other 1950s "utopias" faded away.
Actionable Next Steps:
- Check the map: If you’re planning a drive, look up "The Line Creek Nature Area" on the border of Fayette and Coweta counties; it's a great spot for a hike.
- Register your cart: If you just moved here, head to City Hall on Willowbend Road within 10 days of getting your cart to avoid a fine.
- Verify school zones: If you're moving for the schools, use the Fayette County Board of Education's "Find My School" tool, as city limits and school zones don't always align perfectly.
