Whenever possible, if you are starting a brewery, or any other business for that matter, I would suggest always get a pre-inspection inspection. Having someone come through ahead of when you need your inspection will not only tell you what you need to fix, but also show them (if they are going to eventually do your final inspection) that you are trying to get things correct.
We did this with our electrical, and we are doing this with our Coastal Health inspection. Getting the inspection ahead of time will provide us a with a real list of things that we need to complete, so that when it comes time to get our final, we should (in theory) be good to go.
Inspectors are an important part of the process, as all the work you have done rushing to get to opening day can be lost if you start spinning your wheels on your inspections. Ask Dave at Powell Street Brewing, as they took about an extra 3 weeks to open because they kept getting new things to do from their inspectors. It makes it really hard as a business trying to get off the ground, if you keep getting new things to complete and finish prior to being allowed to open for business.
Anyhow, just a little advice for everyone.
