LOS ANGELES—Apartment owners with additional common space or with already converted ‘bootleg’ apartments may be sitting on goldmines, according to Robert Lopata, president and co-founder of LBPM. His property management company has been maximizing the unit count at vintage 1960s and 1970s apartment product to monetize unused space.

Even better, the process it fairly painless, albeit time consuming. To find out more about which units are ideal for this conversion, the conversion process and the benefits, we sat down with Lopata for an exclusive interview.
