NEW YORK (AP) — A new report from critics of Airbnb and other home-sharing platforms claims New York City could lose nearly 11,000 housing units if new regulations on the companies don’t go forward.

A federal judge this month blocked a New York City law that would have subjected Airbnb and HomeAway to reveal detailed information about their business. The ruling comes as the companies challenge the new law in court.

The groups New York Communities for Change and Tenants PAC issued a report on Tuesday that analyzed government and rental data. It found that without the law, 10,800 units could be diverted for use as short-term rentals.

San Francisco-based Airbnb disputes the report’s findings and says it was created on behalf of the hotel industry to blame home-sharing for high housing costs.
