Airbnb is facing escalating regulation in cities across the USA, including strict new rules in Boston that require hosts to live in their properties for at least nine months of the year and only rent in three, and register them with the city.
The law is designed to ban so-called investor units, ie properties meant to be residential but which are exclusively or primarily used for short-term rentals, which affects local housing stock.
So far 1,778 applications for registration have been received and 737 approved, out of around 4,000 total listings. An Airbnb spokeswoman has said non-licensed listings have now been removed, although city officials have not yet received the data.
The regulations became effective this August 2019 after a legal challenge from Airbnb was settled.
