Just because it is a non-profit, doesn't mean he isn't a highly paid employee or executive of a non-profit. I've read about this on Fox news. Most, if not all, the violations are based on the fact that he charges the public to use his facilities. Open yourself up to the public and you have to deal with the public's laws. I do know that the history and discovery channel usually pays a few hundred thousand dollars to non-profits that they use for their shows. He seems like a pretty good businesses man, he would be a fool if he is getting paid less.

Some states have a waiver on the lumber stamp requirement, most will let you get by with a simple certification from an engineer or a certified lumber inspector. A very small price in comparison to what he is charging.
