Summary
Riverside doesn't require an ADU or MADU to be owner-occupied: neither the primary home nor the accessory unit needs an owner on-site, per §19.442.030(F)(a). JADUs are the exception: one is allowed only if the primary dwelling or the JADU itself is owner-occupied, recorded as a deed restriction.

Full Breakdown
030(F) draws a sharp line between ADU/MADU and JADU rules on owner-occupancy. 030(F)(a) states plainly that neither unit is required to be owner-occupied, an owner can rent out both the main house and the accessory unit without living on the property, reflecting the state-law changes that eliminated owner-occupancy mandates for standalone ADUs. 030(F)(b) allows one JADU on a lot only if the primary dwelling or the JADU itself is owner-occupied, and that condition isn't just a policy, it has to be recorded against the property.
030(A)(10) requires a deed restriction running with the land that both records the owner-occupancy requirement and prohibits selling the JADU separately from the primary dwelling. 030(A)(5) requires ADUs, MADUs, and JADUs to be rented for terms longer than 30 days, which rules out using any of them as a short-term or vacation rental. Together, these provisions let an investor-owned property carry a full ADU without anyone living there, while keeping the smaller, in-home JADU tied to an owner-occupant.
Violations & Fines
Renting a JADU while no one, neither the property owner nor a JADU occupant, lives on-site breaches the recorded deed restriction required by §19.442.030(A)(10) and (F)(b). Because the restriction runs with the land, the City can enforce it against current and future owners through code enforcement or a civil action to compel compliance, separate from any zoning-permit violation for the physical structure itself.
