An alternative here would be a meet in the middle type system where venues could opt into a private regulatory body that entailed obeying a system of rules and regulations, and accepting adjudications of the body in case of conflicts. In return, entities could advertise membership as a selling point, and the regulatory body itself could provide lists of participating entities to anybody who'd like to find, for instance, a higher quality BnB stay at. The system would be funded by entities paying a fee for participation, and perhaps also allowing membership for regular customers as which would entail various promotions and prioritization.

This generally would not work for areas where there is monopolization or where the benefits would be less visible to the consumer in the normal case. what I mean by 'the normal case' is that even a shoddy building won't usually fall down, so abiding and non-abiding entities would seem more or less identical until the 0.01% scenario hits with resultant catastrophe. But things like BnBs are perfect for this model since there is major competition for consumers and transgressions against obviously desirable rules (like no cameras in the house) are not particularly uncommon.

As an aside, the reason I mention this as a desirable option is obviously not because I think there should be any hotels that have e.g. cameras in rooms. But rather because these things never just end at a handful of very critical points. Take food safety as an example. Obviously there are a good number of basic ideas everybody would agree on such as ensuring your hands are cleaned/gloved, that food is reasonably fresh, and so on. But as regularly organizations feel obligated to continue to expand, you start ending up with ever more esoteric rules. For instance in California if your dish cleaning sink for a food stall is 9 inches deep, you're in violation of regulations. They arbitrarily require that a dish cleaning sink must be at least 10 inches deep.

This gradual creep of rules poses an issue to people who are just starting a business. So obviously we all want hotels without cameras and food stalls where servers wash their hands, but on the other hand being forced to read literally hundreds of pages of legalese with countless 'gotchas' that can catch even perfectly safe and desirable products is something that can really hamper entrepreneurship, while simultaneously artificially entrenching older entities. Neither of which I think many people would think is a good thing.
