I wanted to build a bathroom/shower in my garage in order to rent...I know it's probably illegal and I already have someone to rent to at the moment. My question really begins by asking about how much it might cost me to do this? I also wanted to know how about about the whole "legal/illegal" thing. Should I consider another alternative? Would this be "legal" if I hired a inspector and let me know how to build up to code? Lastly, more importantly, how do I find a reputible inspector? or rules for rentiing out a garage?
