Airbnb has criticized new Spanish regulations on short-term rentals, warning they could jeopardize 400,000 jobs and nearly €30 billion in income. The regulations, effective from January 2, require property owners to register and obtain permits, while also collecting sensitive guest information. The Spanish government argues these measures are necessary to combat a housing crisis exacerbated by non-resident property purchases. Despite protests against overtourism, Spain saw a 10% increase in visitors in 2024. Airbnb claims the restrictions will harm rural communities and small businesses, while evidence from other cities suggests such regulations may not effectively address overtourism.
