Airbnb is taking extra precautions this Halloween weekend to prevent unauthorized parties at its rental properties. The home rental platform announced Monday that it will deploy its anti-party technology, which assesses factors such as length of stay, distance from a guest’s location, property type, and booking timing to block reservations considered “higher risk.”

The company emphasized that the technology is part of a broader effort to protect hosts, guests, and local communities while promoting responsible travel. “We lead the way in proactive measures to reduce the risk of unauthorized parties, and our heightened technology for Halloween is one important layer in a comprehensive suite of policies and tools,” Airbnb said in a statement.

This is not Airbnb’s first attempt to curb holiday parties. Last year, the platform prevented roughly 38,000 people in the U.S. and 6,300 in Canada from booking properties during Halloween weekend. The tech has also been used during New Year’s Eve and summer holidays like Memorial Day and the Fourth of July.

Since implementing a ban on parties and events in 2020, Airbnb reports that worldwide party incidents have dropped by 50%. The ban, which became official in 2022, was initially introduced to curb the spread of Covid-19. In 2019, following a deadly shooting at a rental property that left five dead, CEO Brian Chesky announced a crackdown on “party houses” and abusive host or guest behavior.

Airbnb warns that accounts violating the no-party policy may be suspended or permanently banned. The platform also provides hosts with safety features such as a 24-hour safety line and noise sensors to help prevent incidents.
