What Is the Difference Between LA Rent Control and AB 1482?
Justin Borges, DRE #01940318 · 11 min read · Updated July 26, 2026
Los Angeles Rent Control, the Rent Stabilization Ordinance, is a local city ordinance that caps annual increases at 3 percent for buildings generally built before October 1, 1978. AB 1482 is a separate, statewide law that caps most other California rentals at 5 percent plus the local Consumer Price Index change, up to a maximum of 10 percent. A Los Angeles property is generally governed by one or the other, not both at once, and figuring out which one applies changes what a landlord can lawfully charge.

What Is the Difference Between LA Rent Control and AB 1482?
Los Angeles landlords are often surprised to learn they are dealing with two entirely separate laws rather than one rent-control system. The Rent Stabilization Ordinance is a city ordinance, enforced by LAHD, that applies only inside city limits and only to buildings meeting its age and unit-count test. AB 1482, the California Tenant Protection Act, is a state law that applies statewide, including inside Los Angeles, to most rentals RSO does not already cover.
A Los Angeles property is generally subject to one or the other, not a blend of both, and the two laws use different formulas. Confusing which one governs a specific building is one of the most common landlord compliance mistakes in Los Angeles, and it directly changes the lawful rent increase.
Landlords assume AB 1482 means no rent control at all. It usually means a different, statewide formula is doing the capping instead of the city's ordinance.
Justin Borges, CA DRE #01940318Which Los Angeles Properties Are Covered by RSO Instead of AB 1482?
RSO generally covers Los Angeles residential buildings of two or more units with a certificate of occupancy issued before October 1, 1978, along with most mobile home parks established before that date (LAHD). Single-family homes and condos are typically exempt from RSO, with an exception for those owned by a corporation, LLC, or REIT.
When a Los Angeles unit is covered by RSO, that ordinance's own cap governs, and AB 1482 does not add a second layer on top of it. This is the interaction rule most Los Angeles landlords get wrong: RSO coverage means the RSO cap applies, full stop, not RSO plus AB 1482 combined.
Which Los Angeles Properties Fall Under AB 1482 Instead of RSO?
AB 1482 covers most Los Angeles residential rentals that RSO does not reach, including newer apartment buildings and many single-family and condo rentals not otherwise exempt. A Los Angeles building can also be temporarily outside AB 1482's cap during its first 15 years, since the statute exempts construction with a certificate of occupancy issued within a rolling 15-year window (AB 1482).
That 15-year exemption is rolling, not fixed to a single calendar year, so a Los Angeles building's AB 1482 status changes automatically as it ages past the 15-year mark. A landlord relying on new-construction status should track the certificate of occupancy date directly rather than assuming the exemption lasts indefinitely.
How Much Can Rent Increase Under AB 1482 in Los Angeles?
AB 1482 caps annual increases at 5 percent plus the change in the applicable regional Consumer Price Index, up to a maximum of 10 percent total (AB 1482). That formula itself is fixed by statute and has not changed since the law took effect, but the CPI component moves every year and by region, so the exact resulting percentage for a Los Angeles rental changes annually and should be confirmed against the current HCD-published regional figure before a notice goes out, rather than assumed from a prior year's number.
A Los Angeles landlord who wants the precise current maximum for a specific AB 1482-covered rental should check the California Department of Housing and Community Development's published regional CPI figures directly, since this article intentionally does not print a specific year's resulting percentage given how often the CPI input itself changes.
How Much Can Rent Increase Under RSO in Los Angeles?
For an RSO-covered Los Angeles unit, the annual allowable rent increase is 3 percent as of 2026, confirmed directly on the LAHD rent increase calculator. As of February 2, 2026, landlords may no longer add any additional percentage for utilities they pay on the tenant's behalf, an add-on that has been eliminated entirely (LAHD).
| Law | Applies To | Annual Cap | Governing Body |
|---|---|---|---|
| RSO | LA buildings, 2+ units, pre-Oct 1978 | 3% (2026) | LAHD (city) |
| AB 1482 | Most other CA rentals not otherwise exempt | 5% + CPI, max 10% | State of California (HCD) |
Any Los Angeles rent increase notice under 10 percent requires 30 days' written advance notice under state law, regardless of whether RSO or AB 1482 governs the specific unit.
Can a Landlord Raise Rent More Than Once a Year Under AB 1482?
No. AB 1482 limits a landlord to no more than two rent increases within any 12-month period on a covered Los Angeles tenancy, even if the combined total of both increases would still fall within the 5 percent plus CPI, capped at 10 percent, ceiling (AB 1482). This frequency limit is separate from the percentage cap and applies on top of it.
A Los Angeles landlord planning multiple smaller increases across a year to reach the annual maximum should confirm the 12-month lookback window against the specific tenancy's increase history before serving a second notice.
What Exemptions Exist Under AB 1482?
AB 1482's main exemptions include deed-restricted affordable housing, dormitories at educational institutions, housing already subject to a stricter local rent-control ordinance such as RSO, single-family homes and condos owned by a natural person or an eligible trust who provides the required written tenant notice of exemption, owner-occupied duplexes where the owner lives in one unit, and buildings with a certificate of occupancy issued within the last 15 years on a rolling basis (AB 1482).
- Deed-restricted affordable housing
- Dormitories at educational institutions
- Housing already governed by a stricter local ordinance, such as RSO in Los Angeles
- Single-family homes and condos owned by a natural person or eligible trust, with required tenant notice
- Owner-occupied duplexes in Los Angeles
- Buildings within a rolling 15-year window of their certificate of occupancy date
How Do I Know Which Law Applies to My Los Angeles Property?
Start with the certificate of occupancy date and the unit count for the specific Los Angeles building, since those two facts decide RSO coverage first. If RSO does not apply, check whether a specific AB 1482 exemption fits the property, such as natural-person ownership of a single-family home with proper tenant notice. If neither RSO nor an exemption applies, AB 1482's statewide formula is the governing cap.
Because the two laws interact in ways that are easy to get backwards, a Los Angeles owner weighing a rent increase, a refinance, or a sale of a tenant-occupied property often benefits from confirming this classification before making a decision that depends on it.
Frequently Asked Questions
What is the difference between LA rent control and AB 1482?
Los Angeles's Rent Stabilization Ordinance (RSO) is a local ordinance that caps annual increases at 3 percent for buildings generally built before October 1, 1978. AB 1482 is a separate statewide law that caps most other California rentals at 5 percent plus the regional CPI change, up to a maximum of 10 percent (LAHD).
Which Los Angeles properties are covered by RSO instead of AB 1482?
RSO generally covers Los Angeles buildings of two or more units with a certificate of occupancy issued before October 1, 1978. A unit already covered by RSO is governed by the RSO's own, generally lower cap rather than AB 1482's formula (LAHD).
How much can rent increase under AB 1482 in Los Angeles?
AB 1482 caps annual increases at 5 percent plus the change in the applicable regional Consumer Price Index, up to a maximum of 10 percent total (AB 1482). The exact CPI figure changes each year, so confirm the current applicable percentage with the California Department of Housing and Community Development before serving a notice.
Can a landlord raise rent more than once a year under AB 1482?
A landlord may not impose more than two rent increases within any 12-month period on an AB 1482-covered tenancy, even if the combined total would stay within the 5 percent plus CPI, capped at 10 percent, ceiling.
What properties are exempt from AB 1482?
Main AB 1482 exemptions include deed-restricted affordable housing, dormitories at educational institutions, housing already subject to a stricter local rent-control ordinance such as RSO, single-family homes and condos owned by a natural person or eligible trust who provides the required tenant notice of exemption, owner-occupied duplexes, and buildings with a certificate of occupancy issued within the last 15 years on a rolling basis (AB 1482).
How do I know whether RSO or AB 1482 applies to my Los Angeles property?
Start with the certificate of occupancy date and unit count for the specific Los Angeles property, since those two facts decide RSO coverage. If RSO does not apply, AB 1482 is the next law to check, unless a specific exemption listed in the statute applies to that property.
