Although the popularity of short-term rental platforms like Airbnb are skyrocketing in terms of popularity, many listings are in fact illegal rentals. Many apartment buildings have rules and policies in place that are supposed to prevent short-term renters from becoming prevalent. It is a safety issue for many, as the tenants can be in danger if hosts are relying on a constant string of temporary guests and keys are always changing hands. This is especially the case when hosts are not screening properly. Property damage and even death can be the result.
Building Snitch, which hasn't officially launched yet, hopes to help landlord keep illegal rentals from their building. Interested parties can search their building while the service's algorithms search for listings on sites like Airbnb, VRBO, Couchsurfing and Homeaway.
