Interesting, thank you for the information. Though, from your link:

> It nonetheless imposes some pretty firm conditions on vacation rentals and makes the penalties for ignoring them far more stringent. All landlords seeking to rent out their home will only be allowed to do so if they get a general permit from their borough, even if they intend only to rent their property out for occasional short stays. While landlords applying for a permit at their primary residency will likely be approved, second home owners may face a more rigorous process. Landlords who leave an apartment untenanted, meanwhile, will need a special permit from the borough to do so after three months of vacancy without having a permanent tenant registered, cutting the current vacancy grace period in half. Most strikingly, the maximum penalty for breaking the rules has been multiplied by five, to a potential fine of €500,000 ($617,000).
