Summary
In unincorporated Los Angeles County, standard accessory dwelling units carry no owner-occupancy requirement since the County released its covenant interest, but a junior ADU still requires an owner to live in either the main house or the JADU.
Owner Occupancy. If a property contains a junior accessory dwelling unit, either the single-family residence or junior accessory dwelling unit shall be the principal residence of at least one legal owner of the lot... A junior accessory dwelling unit is not permitted on a lot owned by a corporate entity. ... Release of Owner-Occupancy Covenant. The County releases its interest in any covenant for an accessory dwelling unit that required owner-occupancy in perpetuity of either the single-family residence or the accessory dwelling unit that is located on the same lot.
Full Breakdown
County Code § 22.140.640 splits ADUs from junior ADUs on this point. Subsection I releases the County's interest in any recorded covenant that required owner-occupancy in perpetuity for a standard accessory dwelling unit or its principal residence, so those can be rented out without the owner living on-site. Subsection F.2.f keeps the requirement alive for junior ADUs: at least one legal owner of the lot must occupy either the single-family residence or the JADU as a bona fide principal residence, documented at approval, unless the property belongs to a government agency, land trust, or housing organization. A JADU is barred outright on any lot owned by a corporate entity.
Violations & Fines
Building or maintaining a JADU without a qualifying owner-resident, or on a corporately owned lot, breaches the recorded covenant filed with the Registrar-Recorder/County Clerk and exposes the property to County code enforcement and permit revocation.
