# Airbnb Turns On Its AI Party-Blocker for the Fourth of July

As millions plan holiday-weekend getaways, Airbnb has again switched on the machine-learning system it uses to block bookings that look like they could turn into unauthorized house parties — a tool it has refined every year since a deadly 2019 shooting at a rental put the issue on the map.

For the holiday weekend, an algorithm is standing between some would-be renters and a party house.

## How it works

Airbnb says its anti-party system screens each entire-home reservation against more than 100 signals and intercepts the ones that fit the profile of a likely unauthorized gathering, blocking them or steering the guest toward a hotel room or private room instead, [Fox Business reported](https://www.foxbusiness.com/lifestyle/airbnb-deploys-anti-party-technology-ahead-july-4-weekend). The factors, the company says, include how long a guest has had an account, their review history, the length of the stay, how close they live to the listing, and whether the booking is a last-minute reservation over a holiday or weekend — a local renter booking one night raises more flags than a family traveling from out of state.

## Why it exists

The company's party ban and the technology behind it trace to a 2019 Halloween shooting at an Airbnb rental in Orinda, in the Bay Area, that left five people dead and drew national scrutiny to "party houses." Airbnb banned parties globally, then built automated screening to enforce it. By the company's account, the system has blocked or redirected hundreds of thousands of guests worldwide since its rollout, and it credits the effort with a sharp drop in party incidents, [CNBC has reported](https://www.cnbc.com/2023/09/19/airbnb-party-preventer-naba-banerjee-reduced-parties-55percent-in-two-years.html). Over last year's July 4 weekend, Airbnb says it blocked or redirected more than 20,000 higher-risk bookings nationwide, including roughly 2,500 in California. These figures come from the company.

## The Los Angeles angle

Party houses have long been a flashpoint in Los Angeles, where residents in the Hollywood Hills, Venice and other neighborhoods have complained for years about noise, gridlock and property damage tied to short-term rentals, and where police have investigated shootings at rented homes. The city requires hosts to register and generally caps rentals at 120 days a year, with fines for violations, but enforcement has lagged; analyses have found a large share of local listings may not comply with the rules.

## Limits and criticism

The technology is not a cure-all, and it draws criticism. Researchers who study algorithmic systems note that younger guests — who tend to have shorter account histories and fewer reviews — risk being flagged even when their plans are legitimate, and that any model will miss some real offenders. Hosts, for their part, cannot override a block, and some say the screening ultimately leaves them responsible for problems on their property. Community advocates argue that no algorithm substitutes for consistent local enforcement. Airbnb says it pairs the screening with a 24-hour safety line, a neighbor complaint line, optional noise sensors for hosts and a channel for law-enforcement requests — tools that, like the AI itself, will get a workout over the long weekend.
