There was a discussion on this earlier as well but regarding food checks that happen annually if that. Just because it's regulated doesn't mean there is an efficient means in place to assure compliance day in and day out. You're tax dollars are being burned assuring compliance would be an additional burden you don't further want. I think if there is a guarantee of some specified level of sanitary quality (for lack of better word) before you signup for a hotel you are free to sue them if you discover they broke that contract. I know this sounds absurd but you're also free to bring in your own sheets and pillows. My point is that regulation and oversight in this centralized manner should be the last resort.
