The Junta de Andalucia has taken steps to prevent rooms and apartments from being rented to tourists without the owners paying taxes on them.
The Junta has drafted a decree which is due to be ready within six months and which is hoped to prevent more than €100 million per year from escaping the grasp of the tax office on the Costa del Sol alone.
It will also allow for establishments for which until now there was no legal frame, such as Bed and Breakfasts, to legalise their situation.
There will be a register on which all homes which intend to be rented for holidays, even if it is only a room, must be noted.
The aim behind this is to control the market, and each one will be given a registration number.
Last year alone, there were almost 700 reports of illegal rentals in Andalucia, although it is suspected that more than 50,000 properties are rented illegally, with no control, and no guarantee of rights for the clients or the staff.
