But they most certainly can impose enough bureaucracy and other hurdles to make renting factually impossible. Or simply both the incumbent provider and the county employ just a single FTE (or less!) to handle permits, and one can't do anything about it. All while following the letter of the law, because there's nothing in the law that says "county has X days to deal with the permit else it is being automatically granted".
