Short-term rentals
Santa Clarita Chapter 3.34 taxes stays of 30 consecutive days or less at 10% of rent, counting duplexes, triplexes and houses as hotels unless an individually owned house is rented only infrequently.
For investors: A house bought to book guests most weekends will not fit the infrequent-rental exception, so treat the 10% as a charge every booking must carry. The code puts the burden of proof on the owner, so keep a dated log of any occasional stays.

Santa Clarita short-stay operators must register with the city tax administrator within 30 days of starting, post the certificate on site, and file a return by the last day of the month after each quarter.
For investors: The 30-day clock starts when the hosting starts, so file the registration before the first guest arrives. Quarterly returns then fall due April 30, July 31, October 31 and January 31, four extra Santa Clarita deadlines on top of the county tax bill.
