In November 2012, in the aftermath of Hurricane Sandy, Airbnb partnered with New York City Mayor Michael Bloomberg to offer free housing for persons displaced by the storm.[51] Airbnb built a microsite for this effort alone where victims register for housing and meet property owners with free housing.[52] Additionally, Airbnb waived all service fees associated with these listings while maintaining the Host Guarantee for all properties listed.[53]
Some cities have restrictions on subletting for a short period of time. Airbnb has published a list of regulations and requirements for cities in the United States. In some cities, collection of a transient occupancy tax by Airbnb is required. In many cities, hosts must register with the government and obtain a permit or license.[9] Landlords or community associations may have restrictions on short-term sublets.
Another unique thing about software is that, while it can be considered a product, it doesn’t really wear out and get replaced like traditional consumer products. Code and designs created years ago still exist in many places, even after the landscape of a company and its product have shifted significantly. This requires constant maintenance and upgrading.

Shortly after moving to San Francisco in October 2007, roommates and former schoolmates Brian Chesky and Joe Gebbia could not afford the rent for their loft apartment. Chesky and Gebbia came up with the idea of putting an air mattress in their living room and turning it into a bed and breakfast.[16][17] The goal at first was just "to make a few bucks".[18][19] In February 2008, Nathan Blecharczyk, Chesky's former roommate, joined as the Chief Technology Officer and the third co-founder of the new venture, which they named AirBed & Breakfast.[17][20] They put together a website which offered short-term living quarters, breakfast, and a unique business networking opportunity for those who were unable to book a hotel in the saturated market.[21] The site officially launched on August 11, 2008.[22][23] The founders had their first customers in town in the summer of 2008, during the Industrial Design Conference held by Industrial Designers Society of America, where travelers had a hard time finding lodging in the city.[17][24]
