It certainly depends on where you live but almost all jurisdictions have those sorts of requirements. For example, first thing I saw on Google

>Environmental health specialists inspect every hotel at least twice a year or more often as deemed necessary to ensure compliance with the Hotel, Food Service Establishment, and Public Swimming Pool Act of 1985* and the hotel rules and regulations. Current hotel permits must be displayed in a prominent location for the public to view and the inspection report must be available for public scrutiny.

Maybe this is more true of countries like India, where I'm from, where I can imagine hygiene standards being more "flexible". But here in Western Europe for example, or the US, airbnbs are almost better maintained than I'd maintain my own house. And I think there's a good reason for this: the impact of reviews. Even in India, I can't imagine a place going far looking like a cheapo dorm room, because people will definitely look at reviews.
