Have you ever driven through a snooty neighbourhood drooling with envy into the distressed upholstery of your loser motor, wondering who lives in the swankiest domiciles and how they made their dough? Of course you haven't, because you're a Guardian reader, which means you don't roll that way.

But imagine if you did. Wouldn't it be great to have all the data-mined poop so that you could tell which Kardashian lived where and how many toilets they had?

Now you can, at least in the US, thanks to Mansion Map, a new website built for those who want to know where the other half lives and how they got there. Connecticut-based entrepreneur Greg Berry has devised an interactive map that means you can virtually cruise through a neighbourhood finding out who lives where, how much their house is worth, what they do for a living, how much they're worth and, quite possibly, who's their nearest sushi delivery guy.

The site's data is compiled from public records about homeowners' names and addresses, along with searches from Google and websites such as Zillow and White Pages. As a result, you can find out house values, owners' salaries and, in case of extreme celebrity, their sexual history and inside-leg measurements.

But why should anyone want to know this stuff? "Growing up, my favorite hobby was driving through the rich neighbourhoods with my brother," says Berry. "I've travelled the world looking at mansions and now want to share my passion and inspiration with others." And, you'd think, monetise that passion. That said, Berry doesn't counsel that his Mansion Map be used for those of you planning to emulate Emma Watson in concocting Bling Ring-style heists or deploying his data for Robin Hood-like redistribution policies in the manner of Daniel Brühl and his chums in The Edukators, who would break in to rich people's homes, rearrange the furniture and leave taunting notes. No, such activities are illegal and, in any case, Berry has something more counterintuitive in mind.

"Find out what their occupation is and use our tagging system so you and others can find the hidden mansions that will give them inspiration on the path to success," says Berry's press release. "The success of others inspires us in our own lives and careers." Really? Well, perhaps. Maybe knowing where Jennifer Lopez lives, and how many rocks and/or bathrooms she's got, might inspire you to emulate her journey from the humbler days when she was Jenny from the Block.

The launch of Mansion Map comes at a difficult time for the rich and (in)famous in their struggle to prevent the rest of us from knowing where they live and what they're up to. For instance, the Edinburgh home of Sir Fred Goodwin, disgraced former chief of the Royal Bank of Scotland, recently disappeared from Google Street View. You can see other houses on his street, but not his. It was at this house, in 2009, that Goodwin's Mercedes and bay windows were vandalised. Other celebrities including Paul McCartney, Tony Blair, Led Zeppelin guitarist Jimmy Page and singer Lily Allen have had their homes digitally blurred on Google Street View rather than removed, only a few weeks after Google legally acknowledged users' "right to be forgotten".

These days, you might well think, to have your house blurred from Google Street View is the new status symbol, a must-have digital absence betokening your big-ass presence in the world of celebrity. Mind you, you'd think that, if only one house is blurred thus on a street, it might indicate to the rest of us that someone famous lived there. And from that information you could, using similar data-mining techniques to those Berry uses in the US, find out lots more about the people who live there and the secrets they sought in vain to protect. Mansion Map doesn't yet exist in Britain, but certainly the tools to delve into celebrities' privacy – for good or ill – are publicly available.

• This article was amended on 15 July 2014. An earlier version said that celebrities have their houses blurred on Google Street View, while others merely had number plates and faces blurred. Google Street View will blur houses for any user who makes a request, in addition to the automatic blurring of faces and licence plates.
