> Airbnb flophouses are not obliged to conform to fire, health, or safety codes, and they don't pay taxes. Right off the bat, they're scads cheaper than hotels because they don't bear those costs.
Because Airbnbs aren't flophouses. They're holding usually just a couple or family, maybe a dozen people tops unless the place being rented is a really big detached house. Expecting them to be held to the same standards as hotels is not necessary. If this lack of compliance is so dangerous, then why are letting people live in these places full time?
> Visitors and residents have very different incentives. Tourists may wish to stay in cute residential areas, but they are not necessarily interested in being neighborly -- they're not particularly invested in the comfort and safety of the people around them, because they'll be leaving soon.
Tourists also spend more money while on vacation, especially on small businesses like restaurants and bars. More importantly, they bring this money in externally. More tourism attracts the ire of residents that now have to deal with out-of-town people walking around their neighborhood, but I have rarely seen someone complain about negative economic impact of tourism let alone make a coherent argument about why it's bad.
> People do a lot of gross stuff in a hotel that you probably don't want to encounter in your apartment building. Drugs, prostitution, loud parties.
Plenty of people do these things in their apartments, condos, and houses, too.
> No amount of "zoning" is going to make the commingling of apartments and hotels attractive to full-time residents, nor will any change in "zoning" make flophouses less profitable.
Tourists generally don't want to visit residential areas. Airbnb-ing instead of renting a hotel is usually less convenient because the former are further from the city center. When I used an Airbnb in Iceland it was more of a hassle because I effectively needed to rent a car (and then subsequently park a car) to get to the center of the city. It was worth it because of cost. If there were hotel rooms available at the same cost of Airbnb then I would have used that.
However, the number of hotels is usually kept artificially limited. This drives up the cost of renting hotel rooms, which benefits hoteliers. This is the main reason why Airbnb is so much cheaper than hotels. Hoteliers don't want to build more hotels because that would drive their costs down and their expenses up.
