It would depend on which politician you have in your payroll or influence network. If don't have any, get ready for a slow, agonizing, unintelligible maze-like process through twisted Portuguese law, local authorities, government authorities, back to local authorities, different local authorities, back to central government, eventually a little showdown on the court, more laws, and finishing realizing you could have saved a lot of time (and money) and accomplish exactly the same by just ignoring any kind of regulation, and being prepared to pay the fines for doing it.

This is an exaggeration of course, but you're bound to experience this someway, one way or another. Everybody does, no matter what they're trying to do. As for what you specifically asked, I don't know. But I'd like to as much as you...
