File - In this Jan. 25, 2014 file photo, Lorraine Rorke Bader arranges fresh flowers in a room at her home before an overnight guest arrives in San Francisco. Bader rents out the room, with a 3-night minimum stay, for $120 a day using the Airbnb service. Legislation set to be unveiled Tuesday, April 15, 2014, by a San Francisco supervisor would make it legal for city residents to rent out their homes on sites such as Airbnb, but only if they have liability insurance and meet other requirements.
