Not only the media this morning have been reporting this, but also a promt email and link from Airbnb.
The city regulations have not been changed at all. There has always (last few decades anyway) been a strict cap of 60 days (vacation renting) on whole apartments.
Or no cap on renting a room or space that is less than 40% or your own (condo) apartment for any amount of days.
Plus in both cases no more than 4 guests are allowed simultaneously in a rental.
That has been and still is what is legal in the city.
But of course it's been the Wild, Wild West here with innumerable listings for more than 4 guests and non-registered apartments (with the city) rented all year round. Too many hosts and "illegal hotels" undermining regulations and causing huge local disputes in which Airbnb is the scapegoat for everything and anything you can think of.
After all this pressure from the public the city has made an agreement with Airbnb that the max. 60-day cap shall be enforced by the site.
However, this regulation does not apply to official B&Bs and those hosts renting a room or less than 40% of their home with no cap on days per year.
The media says the cap on a max of 4 guests at any given time will also be enforced, though this is not yet reflected in the Airbnb info.
The media also states that hosts of rooms will have to prove they are registered with the city and allowed to rent, but the Airbnb info doesn't reflect this yet either.
As with the 4 guest max. it's to be expected at some point.
What a relief for all hosts who have been adhering to the rules but being blamed by citizens for causing the "Airbnb disruption". The city regulations haven't been changed at all, but hosts disregarding what's legal, whether by accident or wilfully shall now be under more pressure.
The next step planned in the issue is that the city of Amsterdam seems to plan tackling all the other rental platforms the same way.
Since the city is not cracking down on the existing and fair laws themselves but on Airbnb's enabling the ads and thus on those hosts misusing the system, this is so much stronger than suddenly cutting citizens' rights.
