Los Angeles FAQ
What information must platforms share with the city?
Platforms must submit monthly reports listing each Los Angeles property, the host, the registration number, the nights booked, and the gross booking revenue used for transient occupancy tax remittance.
Are platforms liable for an individual host's violations?
Platforms are liable for processing bookings on unpermitted listings and for failing to remove flagged listings, but not for a host's on-site conduct such as noise or unruly-gathering citations.
Does the rule apply to ineligible rent-stabilized units?
Yes. Platforms must remove listings the city flags as RSO units or otherwise ineligible under LAMC §12.22 A.32, even if the host displays a registration number on the listing.
San Francisco FAQ
Why doesn't Airbnb let me list without a registration number in SF?
Police Code 41A.5(g)(4) prohibits platforms from processing bookings on unregistered SF listings. Airbnb fields a real-time OSTR API check and blocks any listing without a valid registration.
Are platforms responsible if a host lies about primary residence?
Platforms are not liable for host misrepresentation but must remove listings within five business days of an OSTR notice and forfeit fees on flagged stays.
