You’re typing a destination into your GPS, or maybe you're looking at a tax bill that makes no sense, and you realize something: there isn't just one Westlake. It's one of those names developers and pioneers absolutely loved. Honestly, it sounds peaceful, right? But if you’re trying to figure out what county is Westlake in, you have to be specific about the state, or you’re going to end up very lost—or paying the wrong treasurer.
Most people are looking for the heavy hitters in Texas, Ohio, or Florida. Each one has a completely different vibe, from billionaire row to classic Midwestern suburbs.
The Texas Powerhouse: Westlake in Tarrant and Denton
If you’re talking about the Westlake that consistently ranks as one of the wealthiest neighborhoods in America, you’re looking at Texas. This is where it gets a little tricky. Westlake, Texas, isn't neatly tucked into one box. It actually straddles the line between Tarrant County and Denton County.
Most of the town's land and its famous corporate campuses—like Charles Schwab and Fidelity—sit in Tarrant County. However, a decent chunk of the residential side, including some of those sprawling estates, reaches over into Denton County. You've got the prestigious Westlake Academy (a municipally-owned charter school) serving the whole town, but depending on which street you live on, your property taxes might be heading to Fort Worth or Denton.
It's a small town with a tiny population (around 1,500 people as of 2026), but its economic footprint is massive. If you're visiting the Vaquero Club, you're definitely in the Tarrant side of the equation.

The Ohio Suburb: Westlake in Cuyahoga County
Switching gears to the Midwest, Westlake, Ohio, is a much larger beast. This is a true city of about 34,000 people. It is located entirely within Cuyahoga County.
You'll find it about 12 miles west of downtown Cleveland. It's the kind of place people move to for the schools and the shopping at Crocker Park. Interestingly, it wasn't always called Westlake. Before 1940, it was actually Dover. They changed the name specifically to avoid being confused with another Dover in Ohio. Sorta funny that they chose "Westlake" to avoid confusion, only for it to become one of the most common place names in the country.
Boundary-wise, it’s tucked in by Bay Village to the north and North Olmsted to the south. If you cross the western border of Westlake, you’ll leave Cuyahoga County and enter Lorain County.
Florida’s Newest City: Westlake in Palm Beach County
Florida does things a bit differently. Westlake, Florida, is basically a brand-new city. It was only incorporated in 2016, making it the 39th municipality in Palm Beach County.

Before the developers moved in, this area was mostly citrus groves and farmland known as the Seminole Improvement District. Now, it’s a massive master-planned community. It’s located in the "Acreage" area, west of Royal Palm Beach. If you’re looking for it on a map, look north of Loxahatchee Groves. Since it's so new, some older maps might not even show it as an official city yet, but it’s definitely there, and it’s growing faster than almost anywhere else in the county.
The Westlake Village Confusion (California)
California has a "Westlake Village," and this is where people usually get a headache. Like the Texas version, Westlake Village is a border-crosser.
The actual City of Westlake Village is located in Los Angeles County. It was incorporated in 1981 as the county’s 82nd city.
However, the "Westlake" community is much bigger than the city limits. About two-thirds of the original master-planned area was actually annexed by the City of Thousand Oaks, which is in Ventura County. So, you can have a Westlake Village mailing address but technically live in the city of Thousand Oaks in a different county.

- Westlake, Georgia: Usually refers to an area in the southwestern part of Atlanta, predominantly in Fulton County.
- Westlake, Oregon: A tiny unincorporated community in Lane County, right on the edge of Siltcoos Lake.

Why the County Matters More Than You Think
Knowing the county isn't just for trivia night. It dictates who picks up your trash, which sheriff's deputy shows up if you call for help, and exactly how much you're going to pay in sales tax.
In Westlake, Texas, the distinction between Tarrant and Denton can mean a difference in which municipal services you access. In California, the county line in Westlake Village determines everything from jury duty locations to which COVID-19 health regulations you had to follow back in the day.
If you’re planning a move or a business trip to any of these spots, double-check your paperwork. A "Westlake" address is rarely enough information on its own.
Actionable Next Steps
- Check the Zip Code: If you’re looking at a real estate listing, cross-reference the zip code with a county map. For example, 44145 is always Cuyahoga (OH), while 76262 usually points toward the Tarrant/Denton (TX) area.
- Verify Tax Jurisdictions: If you're buying property in the Texas or California Westlakes, ask your realtor for a tax certificate to see exactly which county entities are levying taxes on that specific parcel.
- Identify the Correct Government Website: If you need a permit or a marriage license, make sure you're looking at the city's official "gov" site to confirm their specific county seat.
