Hey guys, help me out. I need a reference that gives the minimum bathrrom stall door height in a commercial establishment. Link would be perfect. Who would be responsible for enforcing such a regulation if there is one? Ramifications if it's not installed to code?

Your city and/or county building department would enforce this requirement and it can vary from place to place. Call them and ask, it should have been shown in your prints when they approved them. Ramifications, they can shut down the job, they can fail to give final approval, they can keep you from opening your business. They can swing a pretty big hammer if you mess with them.
