Or, well, lived before his mansion was destroyed and he moved to Amity Park. (By the way, my best guess for Amity Park’s location is that it’s a fictional suburb of Chicago on the Lake Michigan coast, just north of Evanston/”Elmerton.”)
(The writers may have said at some point where he lives, in which case disregard this, but it was fun to think about.)
Door county. More specifically, somewhere between Carlsville and Jacksonport. So about here.
First off, we know he’s in the northern half of the state. At the end of “Bitter Reunions,” Maddie remarks that Jack “beat that ghost all the way to Kenosha,” which is on Wisconsin’s southern border with Illinois. So it’s implied that they were in northern Wisconsin.
Vlad’s a massive Packers fan, so it’s likely he’d want to live somewhere close to Green Bay, probably within an hour’s drive or so. Carlsville is about an hour-and-15-minute drive from Green Bay, not too bad for a fanatic who’d be wanting to show up to every home game. (Yeah, I’m aware that Vlad’s mansion was built by the Wisconsin Dairy King, but you know what, he’s wearing a cheesehead, he’s probably a Packers fan too. Actually I’m pretty sure that if you live in Wisconsin, you’re required by state law* to be a Packers fan anyway.)
(*Blogger’s note: This is not actually a law.)
In the episodes that take place entirely or partially at Vlad’s mansion, it’s shown to be in a wooded, somewhat isolated area. That makes the Marinette or Oconto areas also possibilities, but less likely, since the mansion was built by a wealthy eccentric. Door County is heavily wooded, pretty isolated, and has a pretty low year-round population. It’s also a major vacation destination. So if you’re a wealthy eccentric looking to build a private, lavish estate somewhere nice where you won’t be bothered (this applies to both Vlad and the Dairy King), the middle of the Door peninsula seems like a winner.
But the biggest reason why? It’s a bad pun. The Door Peninsula (and by extension Door County) gets its name from the Porte des Morts Strait, located here. (I put his mansion further south because there’s less tourist activity in that area than there is closer to the strait, therefore more peace, quiet, and people leaving him alone.) Explanations differ on where exactly the name came from, but the most popular is that it was both the site of a large battle and an extremely dangerous and difficult waterway to cross. The name, in French, means “Death’s Door.”
Hm. Death’s Door, Wisconsin. Wonder who’s got one of those in their secret lab.
