Either this guy didn't get his contractor on site before signing a lease, or the contractor is at fault for not mentioning this $20k problem. This is what happens when you skip your due diligence, because any contractor who should be building out restaurants would have known about the grease trap regulations off the top of his or her head. For anyone else thinking of renovations, it's really worth it to get a contractor onsite before you commit. Any competent one will be able to tell you things like hey, widening those door frames 2 inches to bring you up to code is going to be far more expensive than you think it ought to be. etc etc etc. And just wait until you see how much a bit of asbestos on your ceiling is gonna cost you to remediate...
