According to his neighbors, Facebook CEO Mark Zuckerberg has spent way too long and way too much turning a $10 million “fixer-upper” into a “fortress.”

According to a report in the San Francisco Chronicle, a supervisor whose territory includes the Dolores Heights neighborhood says he’s received multiple emails from residents complaining about Zuckerberg’s fixing upping.

Apparently, Zuckerberg’s construction on his 1920s-era home has left some residents flustered over the commotion. The Chronicle paints a picture of “dozens of construction workers, using backhoes and jackhammers, are busy installing everything from a new kitchen to bathrooms and decks — and tearing up the sidewalks for new fiber-optic cables that will connect to the home…” for nearly 17 months, since construction began in April of last year.

Not only that, but some residents have found parking on the street scare, as construction crews have installed “no parking” signs around the site.

In all, Zuckerberg and his wife Priscilla Chan have reportedly taken out millions in construction permits.

If this sounds familiar, that’s because Zuckerberg’s been in the news for his real estate ventures before. This Dolores Heights home? That’s just a second property. Zuckerberg’s original “fortress” sits in Palo Alto. Last year, Zuckerberg reportedly bought up the four adjacent lots, spending between $30 and $43 million on the properties.

Why? Apparently, he just wanted a little privacy. According to Mercury News, Zuckerberg “acted after he learned of a developer’s plan to buy one of the properties next door to the Facebook co-founder.”

Earlier this year, he was sued over that deal.
