Just days ago, we were informed that room services in NY were considered a kind of "apartment information vendor" and that means they need to be licensed. That actually prevents some abuse, so we've started telling 'em to play fair.
Here're the details, from the NY Department of State:
ARTICLE 12-C, REAL PROPERTY LAW
Licensing of Apartment Information Vendors
The definition of apartment information vendor shall include an apartment sharing agent which means any person who, for a fee, arranges, conducts, coordinates, handles or causes meetings between a customer and the current owner or occupant of legally occupied real property, including apartment housing, who wishes to share that housing with one or more individuals as a private dwelling, abode or place of residence,
but it shall not apply to any person who for another and for a fee, commission or other valuable consideration, supervises, organizes, arranges, coordinates, handles or is otherwise in charge of or responsible for the relocation of commercial or residential tenants from buildings or structures that are to be demolished, rehabilitated, remodeled or otherwise structurally altered.
