Usually the answer depends on two things: what kind of building it is, and whether the right sentence is in the lease. Owners of single-family rentals tend to assume the first one settles it. It does not.
The rent cap statute lists six kinds of property it does not apply to (Cal. Civ. Code § 1947.12(d)). Four are rare for a small landlord. Two come up constantly.
The four you can check quickly
- Newer buildings. Housing issued a certificate of occupancy within the previous 15 years is exempt, unless it is a mobilehome (§ 1947.12(d)(4)). The window rolls. A building whose certificate was issued in mid-2011 leaves this exemption in mid-2026, and from then on the cap applies to the next increase. Pull the certificate date from the city’s permit records rather than relying on the year on the listing.
- Deed-restricted affordable housing, or housing under a subsidy agreement for very low, low, or moderate income households (§ 1947.12(d)(1)).
- Dormitories run by a college or a K-12 school (§ 1947.12(d)(2)).
- Units already under a stricter local ordinance (§ 1947.12(d)(3)). This is not an escape from regulation. It means the city’s cap applies instead of the state’s. The California rent control city list shows which cities run one.
Single-family homes and condos: exempt only on paper
A house or condo that can be sold separately from any other dwelling unit is exempt, but only when both conditions in § 1947.12(d)(5) are met.
The owner is not a REIT, a corporation, or an LLC with at least one corporate member. An individual, a married couple, or a family trust usually passes. An LLC owned by two people usually passes. An LLC where one member is an S-corp does not.
The tenant has been given the exemption notice, in the statute’s words. For any tenancy that began or renewed on or after July 1, 2020, the notice has to be in the rental agreement itself. The required statement reads:
“This property is not subject to the rent limits imposed by Section 1947.12 of the Civil Code and is not subject to the just cause requirements of Section 1946.2 of the Civil Code. This property meets the requirements of Sections 1947.12 (d)(5) and 1946.2 (e)(8) of the Civil Code and the owner is not any of the following: (1) a real estate investment trust, as defined by Section 856 of the Internal Revenue Code; (2) a corporation; or (3) a limited liability company in which at least one member is a corporation.”
Copy it word for word. A paraphrase, a shortened version, or a line that mentions only the rent cap is not the statement the statute prescribes. Some older templates still carry a one-sentence version, so check yours against the code section.
Miss the notice and the house is covered. The cap applies to the next increase, and just cause applies once the tenant has been there 12 months.
Three ways a house stops qualifying
- A second unit on the lot. An ADU or a back cottage that cannot be sold separately means the house is no longer “alienable separate from the title to any other dwelling unit.” The Los Angeles Housing Department says so plainly on its Just Cause Ordinance page.
- A change of owner. Deeding the property to a corporation, or bringing a corporate member into the LLC, ends the exemption.
- A renewal without the clause. The notice has to be in the agreement for tenancies renewed after July 1, 2020. A new lease form at renewal that drops the clause drops the exemption.
Owner-occupied duplexes
A duplex is exempt when both units are in a single structure, the owner lived in one of them as a principal residence when the tenancy began, the owner still lives there, and neither unit is an ADU or junior ADU (§ 1947.12(d)(6)).
Every part of that has to stay true. Move out of your half and the exemption ends for the tenant’s unit. Two detached houses on one lot are not a duplex in a single structure. A house with an ADU out back is not this exemption either, which surprises people.
Exempt from the cap is not exempt from everything
The just cause section has its own exemption list, and it is not identical to this one (Cal. Civ. Code § 1946.2(e)). Two examples. A room rented in a house where the tenant shares a kitchen or bath with the owner who lives there is exempt from just cause. So is an owner-occupied single-family home renting no more than two units or bedrooms. Neither of those has a matching line in the rent cap section.
Cities add a layer too. Los Angeles covers single-family homes under its own Just Cause Ordinance even when the state exemption applies, and Oakland’s just cause rules reach many units that are outside its rent control. The Oakland just cause page has the detail.
If the property is covered
Covered tenancies need the statutory notification about the rent cap and just cause, in at least 12-point type, in the lease, an addendum, or a signed notice (§ 1946.2(f)). Then every increase runs through the formula. How to calculate a legal rent increase in California walks through it, and the AB 1482 calculator turns the formula into a dollar amount. The AB 1482 rent increase limits page covers the cap itself.
This is general information, not legal advice. Rules change and local ordinances vary. Confirm current requirements with your city, county, or an attorney before you act.
