As a direct answer to your question, let me offer this: I just started a production brewery in Williamsport. When I called the Pennsylvania Department of Agriculture - the agency that handles the state health codes - I was told that they have no interest in breweries. Only local health codes apply. In our case, we were only inspected for health codes because we operate a small tasting room here. The local health codes official had no interest in the brewery either.
It is up to you to do a LOT of research about your brewery. Call your local codes department and ask someone to do a walk through of your building. Have a couple of drawings outlining where you plan to place tanks and everything else. If you're operating a tasting room, inform them of it and ask what they want to see. Before you even get a building permit, they'll want to see drawings - in most cases professional drawings with an engineer's stamp which can become expensive.
