SFist reports that Airbnb recently paid an undisclosed amount (believed to be $25 million) to the City of San Francisco for an assessed “hotel tax”. San Francisco recently passed an “Airbnb legitimacy law” (available here), allowing tenants to participate in the sharing economy as long as they follow the rules of the regulation (including limitations on number of days per year, registration with the Planning Department, carrying insurance, etc). A proposed amendment – requiring that Airbnb pay back taxes – failed to pass, but Airbnb nonetheless made good on the assessment.
