I don't think you need a lawyer but it wouldn't hurt. I'm not sure about your state but I needed an ABC license and it costs a thousand bucks or so. You have to register with the TTB. In our case we had to have our brewery laid out with actual photos of equipment in place to get the ABC license.
we also needed to be approved by a city council vote. Lots of other local regulation we had to jump through, we hired an architect to design the brewery and tell us what we were going to need to do rather than have to go back and forth with city. IIt worked, we got approved first pass.
I honestly can;t remember much else. Contact your state version of ABC and see what they say, that would be my first step.
