Rialto cannot ban ADU rentals, but state law (Cal. Gov. Code §66314(a)(6)) prohibits renting an ADU for less than 30 days. Long-term rentals are permitted by right; short-term vacation rentals in ADUs are not allowed under state law statewide.
Under Gov. Code §66314(a)(6), a local agency 'shall not issue a certificate of occupancy for an accessory dwelling unit before the certificate of occupancy is issued for the primary dwelling' and 'shall not impose any rental restriction on an accessory dwelling unit other than a prohibition on rentals of less than 30 days.' This means Rialto can — and does, by adopting state law — prohibit ADU short-term rentals under 30 days, but cannot ban long-term rentals or require minimum rent levels. JADUs (Junior ADUs) cannot be rented at all if separated from the main unit; the JADU and main house cannot both be rented under Gov. Code §66333. Statewide rent caps under AB 1482 (Civil Code §1947.12) apply to ADUs that are not exempt single-family rentals — newer ADUs (under 15 years old) are generally exempt from AB 1482's 5%+CPI cap if owner-occupied with proper notice.
Renting an ADU for under 30 days violates state law and can be cited as a zoning violation under RMC Title 18. AB 1482 violations (overcharging rent) can result in tenant lawsuits for damages plus attorney fees.
