even more rentals will become illegal

That is worrying. Thanks for posting I hope the press pick up on this story.

 My understanding is that its similar to the law in  Tenerife where you cannot rent residential developments out to holidaymakers .

It is to stop the complaints from the resident who dont wish to be disturbed by tourists .You can of course rent long term to people who wish to live in the house minimum  months

Thanks for posting the article John. As it says, the Government thinks that if they can somehow stop people from renting out holiday homes the holiday-makers who were looking for a villa with private pool in Spain, will now pay more for a hotel room with communal pool. No. They'll go to Italy or France and Spain will lose all the income that comes with these holiday lets - as they are invariably self-catering, the holiday-makers spend in the supermarkets and restaurants etc, helping keep people in jobs and also employing locals to do the maintenance, gardening, change-overs etc. A lot of people would be affected. I don't know the nitty gritty of the law though and don't fancy ploughing through it in Spanish. I wonder if there is a summary of the main points somewhere, regarding exactly how they think they can shut down this sector.
