Cities from New York to San Francisco are trying to crack down on websites that allow people to rent out their homes, short-term, to strangers. The beachside city of Santa Monica, in Los Angeles county, is the latest.
The new regulations, which go into effect June 15, say any rentals 30 days or shorter can only take place if the owner or permanent tenant stays in the house with the guest during the whole rental. The rules also implement a 14 percent tax on those rentals and mandate business permits.
