Summary
Bellflower requires the property owner to live in either the single-family home or the junior accessory dwelling unit whenever a JADU is built on the lot.
The property owner must occupy either the single-family residence in which the JADU is permitted, or the newly created JADU.
Full Breakdown
Bellflower Municipal Code Section 17.17.020(C)(3) requires the property owner to occupy either the single-family residence in which a junior accessory dwelling unit (JADU) is permitted, or the newly created JADU itself. State ADU law separately requires owner-occupancy for JADUs even while a parallel owner-occupancy mandate for standalone, non-junior ADUs has at times been suspended statewide; Bellflower's provision restates that state-level JADU requirement locally rather than imposing an independent local rule, and it does not extend owner-occupancy to full-size ADUs built without a JADU.
Violations & Fines
Building or renting out a JADU without the owner occupying the main house or the JADU violates Section 17.17.020 and can void the JADU permit or draw code enforcement.
