Owner Occupied Duplex in a Beach City: Are You Really Exempt from AB 1482?

Published July 15, 2026

Yes, but only while you live in one unit yourself, and the exemption disappears the moment you move out, even mid tenancy.

If you live in one unit of a duplex in Manhattan Beach, Hermosa Beach, Redondo Beach, or El Segundo and rent out the other, you are exempt from both the statewide rent cap and the just cause eviction rule of the Tenant Protection Act, but only for as long as you keep living there. Civil Code sections 1947.12(d)(6) and 1946.2(e)(6) both carve out a property with two units in a single structure where the owner occupied one unit as their principal residence at the start of the tenancy and continues to occupy it. The moment you move out and rent both units, that exemption evaporates and both units become subject to AB 1482, on that day, not at the tenant's next renewal.

What the duplex exemption actually requires

AB 1482, the statewide Tenant Protection Act of 2019, put a rent cap in Civil Code section 1947.12 and a just cause eviction requirement in Civil Code section 1946.2 on most residential rental properties in California. Both sections contain a nearly identical duplex carve out. The requirements are specific: the structure has to contain exactly two separate dwelling units, you as the owner had to occupy one of those units as your principal place of residence at the start of the tenancy in question, you have to continue occupying that unit, and neither of the two units can be an accessory dwelling unit or junior accessory dwelling unit. If your duplex includes a converted garage ADU as a third unit, this exemption does not apply at all, because the statute requires the whole structure to contain exactly two units.

The exemption is not permanent, and there is no grace period

This is the part that catches beach city owners. Unlike the exemption for a single family home or condo, which requires the landlord to give the tenant written notice that the property is exempt, the duplex exemption under both sections does not require any notice to the tenant at all. That cuts both ways. It means you did not have to tell your tenant anything when you set up the exemption, but it also means there is no formal off ramp. If you move out of your unit, whether to relocate, deploy, or simply rent out both sides for more income, the exemption ends immediately. There is no phase in period and no grandfather clause for the tenancy already in place. From that point forward, both units are subject to the statewide rent cap (generally 5 percent plus the applicable regional CPI, capped at 10 percent total, over a 12 month period) and the just cause eviction requirement once the tenant has been there 12 months, or 24 months if there is a change of occupancy adding a new tenant during that first year.

Watch local ordinances layered on top

The statewide exemption analysis is only half the picture in the South Bay. Some cities and unincorporated county areas have their own rent stabilization or just cause ordinances that define "exempt" properties differently, or that do not exempt owner occupied duplexes at all. Before you rely on the AB 1482 duplex exemption alone, confirm whether the specific city your property sits in, or unincorporated LA County if that applies, has a separate local ordinance with its own duplex or owner occupancy rules. A property can be exempt from the state law and still be covered by a city ordinance.

What this means for you

If you currently live in half of a duplex and rent the other side, document the date you moved in as owner occupant, since that is the anchor fact for the exemption. If you are planning to move out, know that the exemption ends on your move out date, not at your tenant's lease renewal, so plan your rent increase and any notice to vacate around whatever cap and just cause rules will then apply, and check your specific city's local ordinance before you act.

If you want a second set of eyes on whether your duplex still qualifies before you make a move, that is exactly the kind of question we help owners work through.
