It would be interesting to see what actually "right" they have to come on your property and check for such things.
Here the Game Wardens abuse their power by quite a bit. I read the regulations on what they can and cannot do, and I would say that 90% of what they do is actually consider trespass by law. They continue to do it because most of the people are afraid to stand up to a person "in power". I'm not. I have nothing to hide, but right is right and wrong is wrong. Simply saying, "can I see your warrant", typically sends them packing. I farm right and do things accordingly and they should as well. If they would like to waste their time, waste the judges times and come back with paperwork in hand, they are going to be sorely disappointed, but if they think they can just ride around on my land and do some snooping...sorry that's trespass.
To answer your question though, yes my house and shop is inspected every year by the State Fire Marshall. That is because I am a foster parent and that is part of the requirements. I have no issue with this since I am the one that decided to be a foster parent and have a contractual, and moral obligation to be safe and compliant. That's not a privacy right that's lost, it is a voluntary situation I allow by agreeing to being a foster parent. Hopefully I don't sound like a hypocrite by saying all this.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
