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).
Night-cap regulations are a deliberate housing-supply tool used by larger California cities to balance tourism revenue against displacement of long-term rentals. Rialto's Inland Empire / logistics-corridor economy, smaller tourism base relative to coastal cities, and absence of a dedicated STR ordinance mean no such cap was adopted. The only nightly limit embedded in Rialto's framework is the 30-consecutive-day threshold separating taxable transient stays (subject to 9% TOT) from longer-term residential tenancies. Hosted (owner-occupied) and unhosted (whole-home) configurations are treated identically — neither has a night cap, but both require business licensing and TOT remittance. State law forbids short-term renting an ADU/JADU built under Gov. Code §65852.2 regardless of city rules; the unit must rent for 31+ days.
Operating without a business license or failing to remit TOT triggers Title 5 / Chapter 3.08 enforcement (back tax + 10% delinquency penalty + 0.5%/month interest). No 'over-cap' citations exist because there is no cap.
