New York City regulators are cracking down on short-term Airbnb listings as it’s eating into the long-term rental market. As a result, thousands of Airbnb rental options in the city have vanished.

By September 5, short-term rental hosts in NYC will need to register with the city authorities or have a Class B status to continue hosting. Airbnb hosts must also abide by certain rules.

Fines for Airbnb and the host can range from $100 to $5,000 for not abiding by the regulations. The move comes at a time when an affordable housing crisis looms over the country.
