San Bernardino County
Rialto does not impose an annual cap on the number of nights a host may rent short-term. Unlike Los Angeles (120 nights unhosted), San Francisco (90 nights unhosted), or Santa Monica (no whole-home STRs allowed), Rialto MC contains no night-cap provision. A host with a Rental Income Property business license under Title 5 and current TOT compliance under Chapter 3.08 (9% rate, transient = ≤30 consecutive days) can theoretically operate 365 nights/year. ADUs and JADUs remain capped at 30+ day minimum terms by Cal. Gov. Code §65852.2(a)(6).
