Steven,
In all municipalities they want your money, so in saying that, yes you will need to have a permit. The company constructing the building in some or most cases will acquire the permits for the building, discuss this with the company as to what they will do; also do you want windows, that's extra. There is several style of steel buildings besides what is shown in the pictures so you may want to look at what other companies have to offer as well.
I suggest before you go to far with your acquiring the contract on the building, you project all the costs before you start, that way you wont have any surprises.
Best to you in your new adventure,
Bob
