Not that simple. It's not just the Fed requirements that you have to deal with but the State and Local municipality....which more often, is the stickier stuff. We started backwards...going for local, then State, then Fed licenses. All will require you to submit some sort of drawing and/or description of the site. My guess is that going the way you are proposing will actually create more paperwork in the filings of amendments, changes, and other red tape documentation. You would be better off finding the place that you want to open your doors from and striking a deal with the seller or landlord that was structured on a sliding scale....less $$ for the first 6 months and then gradually more once you got open. Worked for us.
