As of my last update in January 2022, Ibiza, like many popular tourist destinations, had been implementing regulations to manage the growing market of short-term vacation rentals. These regulations aimed to strike a balance between the booming tourism industry and the needs of local residents. Here are some aspects of the regulations that were being implemented:

1. Licenses and Permits: Property owners were required to obtain specific licenses or permits to legally rent out their properties to tourists. These licenses often came with certain criteria that needed to be met regarding safety standards, property conditions, and tax compliance.
2. Rental Duration Limits: Some areas in Ibiza were imposing restrictions on the number of days or months a property could be rented out as a vacation rental. This was to prevent long-term housing from being converted solely into short-term accommodations.
3. Taxation and Fees: There were regulations in place related to taxation on rental income. Property owners were required to comply with tax laws and pay the necessary fees associated with renting out their properties.
4. Community Impact: Regulations also aimed at mitigating the impact of tourism on local communities. This involved concerns about noise, waste management, and maintaining the integrity of residential neighborhoods.
