The Boz Bosworth In Deep Over The OC Mansion

Boz used to own the giant Malibu mansion -- featured prominently on Season 1 of the TV show -- and he rented it out to a company called Grasshopper House LLC in 2006, which currently runs the famous Passages rehab center down block. Boz has since sold the house.

But things didn't go so well between Boz and Grasshopper -- which claims the property's septic tank went out between 2008-2009 ... and GH was forced to sink over $50,000 of its own money into fixing the problem.
