I would start with the regulations required of hotels and serviced apartments that exist now. These are fairly diverse and fairly specific. Safety today is good and there is a reason for that. New players. i.e. AirBNB owners, should be held to no less of a standard. Simply owning a residential property does not qualify one to become a hotel level lessor.
Out of curiosity though, you do not advocate government interference with regulations regarding leasing conditions and responsibilities yet appear in the last statement to advocate government interference in the allowance of the very existence of structures. Clarification on where the lines for safety should be drawn?
I think the primary case for government regulation is where there are externalities, i.e. if my house catches on fire it will burn the whole neighborhood down. If I drive to fast, I may injure others, etc. I also believe that sellers of products or services need to provide full and adequate information on what they are selling. I.e. it's fine to sell a garbage product, you just need to let customers know the product is garbage.
Again I would ask though what are the regulations specific to lodging that are needed for safety reasons. If I were a skeptical person, I'd be tempted to think the new regulations had little to do with actual safety and more to do with shielding the lodging industry from competition and to discriminate against residents and visitors from poorer countries.
