California Cities Can Now Pull Your Airbnb Data: An STR Host's Guide to SB 346 and Transient Occupancy Tax Compliance
Since January 1, 2026, California's SB 346 lets any city or county with a conforming ordinance require Airbnb, Vrbo and other platforms to report each short-term rental's address, assessor parcel number and listing URL as often as monthly, backed by fines of up to $10,000 per day. Covers which cities already enforce (Los Angeles, Santa Monica, San Diego), how transient occupancy tax works and who owes it, what back assessments with 10–25% penalties look like, and a plain-text bookkeeping setup that books TOT to a liability account, records platform-remitted tax, and reconciles channel by channel.
