Eastvale, CA Accessory Structures: ADU Owner Occupancy (2026)

010(f)(5) draws a line between a full accessory dwelling unit and a junior accessory dwelling unit on the owner-occupancy question. ' A JADU is different only when it shares sanitation facilities, meaning a bathroom or kitchen, with the primary residence; in that scenario the code requires that one of the two units on the lot be owner-occupied. The one carve-out is for a JADU or ADU on a lot owned by another governmental agency, land trust, or housing organization, which is exempt from the owner-occupancy condition even when facilities are shared, recognizing that affordable-housing operators do not have a resident owner to occupy either unit.

A JADU built with its own separate, independent sanitation facilities avoids the owner-occupancy trigger entirely, since the requirement is keyed specifically to shared facilities. The city enforces this through the deed restriction required by subsection (f)(6), which the property owner must record before a JADU permit is finalized, giving code enforcement a recorded instrument to check if an owner later stops occupying the property.
