I too live in the land of the free and permits are seldom required for residential construction. The only permits that I have ever dealt with were for electrical service panels, and that was required by the utility, not the municipality, county or state government. When I built my house, there were no permits or inspections required other than for the electrical. As someone else mentioned, we are free to do any type of plumbing or electrical work for ourselves, but can't (legally) do it for others.
I think technically we are supposed to get plumbing permits for repairs/expansions/etc., but if I don't have to, I won't get a single permit.
I have worked with some church's that have done some expansions and because we are commercial (relatively speaking) structures, we have gone through process for state building permits and inspections. It is a cumbersome and time consuming process, but I will have to say that it was not altogether unpleasant or too expensive (about $200 for the plan review) and the inspector (same guy each time) was always good to work with.
