If you’re driving through the rolling hills of Metro Detroit and suddenly find yourself surrounded by lush parks, high-end shopping, and some seriously impressive real estate, there’s a good chance you’ve landed in Rochester Hills. But if you’re trying to mail a package or figure out who handles the local taxes, you’re probably asking the big question: what county is Rochester Hills in?
The short answer is Oakland County.
Honestly, it’s one of the most prominent spots in the entire state of Michigan. But just knowing the name of the county doesn't really tell the whole story. Rochester Hills isn't just a random dot on the map; it’s a massive, 32-square-mile powerhouse that basically defines the upscale suburban vibe of the Detroit outskirts.
Why Everyone Gets Confused About Rochester vs. Rochester Hills
People mix these up constantly. It’s kinda funny, actually. You have Rochester, which is this charming, historic city with a walkable downtown and the famous Big Bright Light Show during the holidays. Then you have Rochester Hills, which completely surrounds Rochester like a donut.
While they share a name and a school district, they are totally separate entities.
Rochester Hills used to be called Avon Township. Back in the day—we’re talking 1984—residents decided they wanted to become a city to protect themselves from being "gobbled up" by neighboring areas through annexation. They chose the name Rochester Hills because, well, the terrain is actually hilly and they wanted to lean into the prestige of the Rochester name.

The "Hidden" History of the Area
Before it was a tech hub, this land was home to the Potawatomi. In 1817, a guy named James Graham became the first European settler. He followed Native American trails up from Detroit, probably looking for good farmland and water.
He found both. The Clinton River, Stony Creek, and Paint Creek provided enough water power to run mills. By the mid-1800s, this part of Oakland County was a thriving agricultural zone. You can still see that history at the Yates Cider Mill. It’s been running since 1863. If you live in Michigan and you haven’t had a donut and cider at Yates in the fall, do you even really live here?

Actionable Tips for Newcomers or Visitors
If you’re planning a move to this part of Oakland County or just visiting for a weekend, here is how to make the most of it:
Check the School Boundaries
Just because you have a Rochester Hills address doesn't mean you're in Rochester Community Schools. Parts of the city fall into the Avondale School District. Both are great, but it’s a detail you’ll want to double-check if you're buying a house for the schools.
Visit the Village
The Village of Rochester Hills is an outdoor shopping mall that feels like a little town square. It’s at the corner of Adams and Walton. It’s the place to go for Whole Foods, Lululemon, or just a nice walk when the weather is decent.
Explore the Trails
The Paint Creek Trail and the Clinton River Trail both run through here. You can bike for miles, connecting to other Oakland County cities like Lake Orion or Pontiac without ever really touching a main road.
Know Your Trash Day
It sounds boring, but since Rochester Hills is a city within a county, they have specific contracts for things like waste removal. Most of that info is handled through the city’s official website, not the county’s.
Knowing that Rochester Hills is in Oakland County is the first step in understanding one of Michigan's most successful suburbs. Whether you're there for the robotics jobs, the top-tier schools, or just a glass of cider at the mill, it’s a place that manages to feel like a small town while having the resources of a major economic engine.
