Like many above stated, it will all depend on the local HD. In Denver we weren't required to serve from an enclosed area, only had to have a handwashing station & a commissary to take dishes to clean up after. In Jacksonville you have to have an enclosed space like a food truck/ concessions trailer w sliding service window & a bunch more. (No outdoor cooking). It also depends on what license you operate under? Mobile Food Vendor, Vendor, Caterer, Etc.... Call your local HD or at the very least a local well used commissary. Most of them are pretty helpful. Worth picking up the phone. Cheers
