If your rental property sits in an unincorporated part of Los Angeles County — not inside the city limits of Los Angeles, Long Beach, Glendale, or any other incorporated city — a separate rent law applies that has nothing to do with the Los Angeles City RSO most landlords have heard of.

The County of Los Angeles enacted its own Rent Stabilization Ordinance for unincorporated areas effective April 1, 2020, administered by the Department of Consumer and Business Affairs (DCBA), and it covers an entirely different set of communities: places like East Los Angeles, Florence-Firestone, Willowbrook, Altadena, Val Verde, and dozens of other unincorporated pockets scattered across the county.

Here is what it actually requires, and why confirming whether a property is even subject to it is the first step before listing or selling.

Getting the jurisdiction and the exemption analysis wrong before a listing goes live is the most common and most avoidable mistake owners in these unincorporated pockets make.

How to Tell If a Property Is Even Covered

Because Los Angeles County contains dozens of incorporated cities carved out of its territory — each with its own municipal government and, in some cases, its own separate rent control ordinance — “unincorporated Los Angeles County” is not a simple geographic shorthand.

A property can sit on a street where one side is unincorporated county land and the other side is inside a city boundary, subject to entirely different rent rules.

The county directs residents and owners to its “Find Your District” lookup tool through the Registrar-Recorder’s office to confirm an address’s actual jurisdiction before assuming either way.

Skipping this check is a common and consequential mistake: an owner who assumes a rental is covered by a neighboring city’s ordinance, or assumes it isn’t covered by anything at all, can end up non-compliant with a law they didn’t realize applied.

How This Ordinance Came to Exist

Los Angeles County did not have a standing rent stabilization program for unincorporated areas before 2019.

The Board of Supervisors first adopted a temporary rent cap and eviction moratorium for those areas in response to housing-cost pressure, then converted it into the permanent Rent Stabilization Ordinance that took effect April 1, 2020 — just as the COVID-19 pandemic was beginning, which led the county to layer a separate, temporary eviction moratorium and rent freeze on top of the new permanent ordinance for roughly the next year and a half.

That emergency overlay has since expired, but it’s a reason some older online guidance about this ordinance still describes rules that applied only during the pandemic emergency period and no longer reflect the ordinance’s standing, permanent terms.

Anyone researching this ordinance should confirm they’re looking at current DCBA guidance rather than an archived page describing the 2020–2021 emergency rules.

The Rent Increase Cap

For covered units, the ordinance sets an annual maximum allowable rent increase tied to the regional Consumer Price Index, with a hard ceiling the county has set at 8% regardless of how high CPI runs in a given year.

Some unit types and tenancies qualify for exemptions from the cap — certain newer construction, owner-occupied properties with a limited number of units, and a few other categories carved out by the ordinance and by the statewide Costa-Hawkins framework it sits on top of.

An owner who raises rent above the allowed percentage on a covered unit is exposed to a tenant petition and potential liability for the overage, independent of anything happening with a pending sale of the property.

Put in concrete terms: on a unit renting for $1,800 a month, an 8% cap allows an increase of up to $144, bringing the rent to $1,944 — but only if CPI growth that year is high enough to justify the full 8%.

In a year where the relevant regional CPI figure comes in lower, the allowed increase is whatever that lower CPI percentage works out to, not the 8% ceiling by default.

The 8% is a cap on the CPI-based formula, not a guaranteed annual increase, and an owner who raises rent by 8% in a year when the CPI formula only supports 4% has still violated the ordinance even though 8% is the number most often quoted.

How the County Ordinance Interacts With Statewide AB 1482

Even a unit that qualifies for one of the county ordinance’s own exemptions doesn’t necessarily escape rent and eviction regulation altogether, because California’s statewide Tenant Protection Act (AB 1482) imposes its own separate rent cap and just-cause requirement on most rental housing more than 15 years old, regardless of local ordinances.

A single-family home or newer condo that falls outside the county ordinance’s coverage because of a local exemption can still be squarely inside AB 1482’s statewide cap if it doesn’t separately qualify for one of that law’s own exemptions — the small-landlord single-family-home exemption, for instance, requires specific written notice language in the lease to apply.

Checking only the county ordinance and concluding a property is unregulated, without separately checking AB 1482, is one of the more common compliance gaps sellers and buyers run into in this part of the county.

Just Cause Protections Reach Further Than the Rent Cap

One detail that catches owners off guard: the ordinance’s just-cause eviction requirement applies more broadly than the rent cap itself.

A unit that is exempt from the rent increase limitations can still be covered by the just-cause protections, meaning an owner can’t simply terminate a tenancy without one of the ordinance’s specified reasons — nonpayment, lease violation, owner move-in, or a handful of other defined grounds — even on a unit where rent increases aren’t capped.

Selling a property does not, by itself, create a basis to terminate a tenancy under local or state law; a new owner inherits the existing tenancy and the same just-cause limitations the seller was operating under, which is worth confirming before a buyer assumes they can simply ask tenants to leave after closing.

Annual Registration

Covered properties have to be registered annually with DCBA, with updates reported whenever tenancy, rental rate, or amenities change.

The county waived registration fees for a period after the ordinance first took effect, and whether a fee currently applies — and how much it is — is the kind of detail that changes with county budget decisions, so an owner or a buyer’s agent should confirm the current fee schedule directly with DCBA (rent.lacounty.gov, or (833) 223-RENT) rather than relying on an older notice.

An unregistered covered unit is a compliance gap a title company or a cautious buyer’s attorney may flag during due diligence, and it’s considerably easier to clear up before a sale than to discover and fix during a tight escrow.

Catching up a lapsed registration generally means filing the missing annual updates and paying any accrued fees before the sale, not simply registering as of the current date, so an owner who hasn’t kept registration current for several years should budget both time and money to bring the file up to date rather than assuming a single quick filing will resolve it.

Relocation Assistance for No-Fault Terminations

Where a tenancy ends for a “no fault” reason — most commonly an owner move-in, a planned substantial remodel, or a temporary displacement for repairs — the ordinance requires the owner to pay relocation assistance to the displaced tenant.

The amount and the specific triggering events are spelled out in the county’s own fact sheets and are periodically adjusted, so an owner planning a sale that anticipates vacating a unit for any of these reasons should confirm the current relocation figures with DCBA before finalizing a timeline, rather than budgeting from an outdated number found online.

This is one of the areas most likely to catch a seller by surprise, because the relocation obligation is the seller’s to satisfy regardless of whether the unit sells before or after the tenant moves out.

The Measure W Pass-Through

A detail specific to this ordinance, and not found in most city-level rent programs, is the Measure W parcel tax pass-through.

Measure W, approved by county voters in November 2018 to fund stormwater infrastructure, imposes a parcel tax that owners of properties with 50 or fewer rental units are permitted to pass through to tenants as a cost separate from the capped rent increase.

This pass-through has to be itemized and disclosed correctly — it isn’t simply added into the rent as if it were part of the increase — and a seller should be prepared to show a buyer exactly how any Measure W charges on the property have been handled, since a buyer inheriting the tenancy inherits that disclosure obligation too.

Fair Return Petitions and Pass-Through Costs

Owners who believe the capped rent increase doesn’t allow a fair return on the property, often because of a significant change in operating expenses, can petition DCBA for an additional increase outside the normal cap.

Separately, owners can petition to pass through a portion of specific costs — certain capital improvements or legally mandated repairs — to tenants outside the standard rent increase.

Both processes require documentation and a formal petition; neither happens automatically, and both are the kind of pending administrative matter a buyer’s attorney will want disclosed if a petition is in progress at the time of sale, since the outcome could change the unit’s rent roll after closing.

Fair-return petitions in particular tend to take months to resolve once filed, since DCBA has to review the owner’s documented operating expenses and compare them against the property’s rent roll before approving any increase beyond the standard cap.

An owner who files a fair-return petition shortly before listing a property for sale should expect that petition to still be pending at closing more often than not, which means the buyer is effectively purchasing a property with an open administrative matter attached — worth flagging clearly in the purchase agreement rather than leaving it to come up during the buyer’s own due diligence.

How This Differs From the LA City RSO

Owners who also hold property inside the City of Los Angeles sometimes assume the two ordinances track each other closely. They don’t fully.

The City’s Rent Stabilization Ordinance predates the county’s by decades, uses a different increase formula and registration system administered by the Los Angeles Housing Department rather than DCBA, and has its own separate case law and enforcement history.

An owner managing a portfolio split between unincorporated county parcels and incorporated-city parcels — including properties inside Los Angeles proper covered by programs like REAP or subject to the SCEP inspection fee — is effectively running two different compliance systems side by side and should not assume a form, notice, or registration filed correctly under one ordinance satisfies the other.

Enforcement and What It Means for a Pending Sale

DCBA handles tenant complaints and petitions administratively rather than through the criminal courts, but an owner found to have overcharged rent or terminated a tenancy without just cause can be ordered to refund the overcharge, and in some cases face additional penalties.

A tenant with an active, unresolved complaint against the current owner at the time of a sale creates a liability question a buyer’s attorney will want answered before closing: does that liability transfer with the property, or does it stay with the selling owner personally?

The honest answer is that it depends on the specific facts and how the purchase agreement allocates pre-closing liabilities, which is exactly the kind of open question that benefits from being resolved, or at least clearly disclosed and allocated in writing, before escrow closes rather than discovered by the buyer afterward.

Disclosure Expectations in a Sale

Beyond California’s standard Transfer Disclosure Statement requirements, a seller of a rent-stabilized unit in unincorporated LA County is generally expected to disclose the existing tenancy terms, the current legal rent, the registration status, and any pending petitions or complaints as part of ordinary due diligence — even where no single statute spells out “disclose your DCBA registration number” in those exact words.

Buyers who specialize in rent-controlled property routinely request this information directly as part of their offer process, and a seller who can produce clean registration records and a documented rent history tends to see fewer price adjustments during negotiation than one who shows up with gaps in the paperwork, since a buyer who has to reconstruct that history themselves will typically price in the extra time and risk.

Incomplete records don’t necessarily kill a deal, but they commonly become a point of renegotiation once a buyer’s side discovers them during inspection or title review.

Selling a Covered Rental As-Is

None of this ordinance prevents a sale — it simply means the sale carries the registration status, the rent roll history, and the existing tenancy terms into the new owner’s hands.

For an owner who inherited a tenant-occupied unincorporated-area rental, perhaps through a family estate, and has no interest in managing DCBA registration, fair-return petitions, or relocation obligations going forward, selling the property with the tenant in place — rather than trying to clear the unit first, which triggers its own notice and relocation requirements under the ordinance — is often the simpler and faster path.

A buyer experienced with rent-stabilized property in Los Angeles County can take on the existing registration and tenancy without requiring the seller to navigate a vacancy first, which removes the relocation payment, the notice periods, and the vacancy carrying costs from the seller’s side of the transaction entirely.

Before Listing a Covered Unit

Confirm the property’s exact jurisdiction through the county’s district lookup tool rather than assuming based on the mailing address or ZIP code.
Verify the unit’s current DCBA registration status and whether any registration fees are outstanding.
Check whether any fair-return or pass-through petitions are pending that could change the rent roll after closing.
Call DCBA directly at (833) 223-RENT for the current rent increase cap, relocation figures, and registration fee — all of which are adjusted periodically and should never be assumed from an older printout.
