Answer 1

When you order your trusses. Make sure you order bonus room style trusses (open rafter/truss). This way you can deck, insulate and finish it when your ready without clasifying your home as a two story structure at the initial build.

However, when you pull the permit for the upgrade it will then be listed as a two story structure.  

Answer 2

It's not style that you need to worry about..it's zoning.
