Just to clarify, I've never done it. I don't see why it would be illegal... The scenario I was describing does NOT include any 'permanent' residents. They would be there just during normal biz hours (like 10am - 7pm mon-fri). For legal reason, maybe one guy could be the permanent resident and invite 2 or so friends to come use the apt as an office (away from chores, kids, distraction) and help pay part of the rent? I first heard about an apt being used as office space while reading this book by Jessica Livingston: Founders at Work: Stories of Startups' Early Days Ann Winblad is one of the founders interviewed in the book and she talks about using a 2-bed apt as the first office space for her startup, in late 1970s. I just find the co-working space to be obscenely expensive, especially for someone on limited income.
