Easy to test for, though I'm not sure if you can do it for free like skillcat used to offer.
And in my state, I copy pasted what was required for a 'residential' HVAC license (idk if you meant commercial HVAC or just making money on installs).
Environmental law is the same way. You're mostly (details depend on jurisdiction) not supposed to pave anything without getting permission but if they pushed the issue on everyone who put a pad under their car port the rules would get changed.
They also don't 100% enforce the speed limit either.
Idk for Americas, but here in rural EU no one would give a fuck. Some will ask for help.
