How to Legally Terminate a Tenancy in 2026: What Orange County and LA Landlords Need to Know
If you own a rental property in Orange County or Los Angeles County — especially one with an ADU or junior ADU — the rules around ending a tenancy are not as simple as handing someone a piece of paper and asking them to leave. The Tenant Protection Act of 2019 (AB 1482) created a statewide framework that controls when, how, and with how much notice a landlord can terminate a periodic tenancy. Layer local ordinances on top of that, and the process gets specific fast.
This post walks through what's required in 2026 — notice periods, just cause reasons, relocation obligations, ADU-specific exemptions, and the form landlords need to use.
The Legal Foundation: AB 1482 and the Tenant Protection Act
California's AB 1482 does two things: it caps annual rent increases for covered tenants, and it requires just cause before a landlord can end a tenancy. Both provisions have exemptions — but those exemptions must be properly documented to hold up.
If your property is covered by AB 1482, you cannot terminate a tenancy without a legally valid reason. The law distinguishes between at-fault just cause (the tenant did something wrong) and no-fault just cause (the tenant did nothing wrong, but the owner has a legitimate reason to reclaim the property).
At-fault just cause includes things like non-payment of rent, lease violations, nuisance, and criminal activity. These terminations use separate CAR forms — the PRQ (Pay Rent or Quit), PCQ (Cure or Perform Covenant), or NTQ (Notice to Quit) — and generally carry 3-day timelines.
No-fault just cause is where the Notice of Termination of Tenancy (C.A.R. Form NTT) comes in. The four allowable no-fault reasons under AB 1482 are:
Owner or family member move-in — the owner, spouse, domestic partner, parents, grandparents, children, or grandchildren intend to occupy the unit
Withdrawal from the rental market — the owner is pulling the unit off the market entirely
Demolition or substantial remodel — the unit must be vacated to complete the work
Government or court order — a habitability order or local ordinance mandates the vacancy
For each of these, the required notice period is 60 days, and the tenant is entitled to relocation assistance equal to one month's rent — either as a direct payment within 15 calendar days of the notice, or as a waiver of the final month's rent.
Notice Periods: 30 Days vs. 60 Days
For tenancies not covered by AB 1482 (more on that below), the notice period depends on how long the tenant has lived in the unit:
30 days — if at least one tenant has occupied the premises for less than one year
60 days — if all tenants have occupied for one year or more
90 days — if the tenant is a beneficiary of a government rental housing assistance program
For no-fault terminations under AB 1482 (covered properties), the notice is always 60 days — and it must state the specific just cause reason. A generic notice without a stated reason is legally defective and won't support an unlawful detainer action if the tenant refuses to leave.
The ADU Exemption Most Owners Don't Know They Have
Here's where ADU owners in particular need to pay attention. Under AB 1482, single-family owner-occupied residences where the owner rents no more than two units or bedrooms — including ADUs and junior ADUs — are exempt from just cause eviction requirements.
This means: if you live in the main house on a single-family lot and rent out an attached ADU or JADU, you likely don't need a no-fault just cause reason to terminate that tenancy. You can end the tenancy with proper notice alone.
But the exemption only holds if:
The owner gave proper written notice of the exemption before or at the start of the tenancy (a Civil Code § 1946.2(e)(8)(B)(i) notice)
The property is not owned by a corporation, LLC with a corporate member, or REIT — it must be owned by a natural person
If that exemption notice was never served, you may lose the ability to claim it now. This is one of the things worth checking before you write any offer on an investment property in OC or LA — the prior owner's compliance history can become your problem.
Other common AB 1482 exemptions include:
Buildings constructed within the last 15 years — as of 2026, that means units built after 2011
Owner-occupied duplexes — if one unit was owner-occupied at the commencement of the tenancy and throughout
Tenants who share kitchen or bathroom facilities with the owner
Los Angeles County: The Local Layer
If your property is in the City of Los Angeles, AB 1482 is not the only framework you're working under. The City has its own Just Cause for Eviction Ordinance (JCO) — and it's stricter than state law in several ways.
Under the LA JCO, any written notice terminating a tenancy must be filed with the Los Angeles Housing Department (LAHD) within three business days of serving it on the tenant. Miss that window and your notice has procedural problems.
Owner move-in evictions under the LA JCO also come with a 36-month owner occupancy commitment. If you move in a family member and they're gone in 6 months, that's a problem. The LAHD eviction notice page has current filing requirements and checklists.
If your property is in unincorporated LA County — not inside any city limits — you're operating under county rules rather than the City of LA's ordinance. LA County's 2026 ADU ordinance amendments changed some of the development rules this year, but the eviction framework for unincorporated areas still runs primarily off state law. Verify your jurisdiction before you assume the same process applies.
For investors buying multi-unit properties in LA County with the intent to add density or eventually reclaim units, understanding the termination framework for existing tenants is as important as understanding the construction pathway for new units. Both affect your timeline.
Orange County: State Law Is the Baseline
Most cities in Orange County do not have their own local rent control or just cause eviction ordinances — they operate under California's statewide AB 1482 framework. That means the notice periods, just cause requirements, and exemptions described above are the operative rules.
Markets like Anaheim, Garden Grove, and Costa Mesa follow the state framework. For landlords in those cities, the process is cleaner: identify whether your property is covered or exempt, serve the correct notice, and comply with state-level relocation assistance rules if the termination is no-fault and the property is covered.
That said, if your property is in a city with its own ordinance — even a partial one — you need to verify local rules before you serve anything. Penalties for non-compliance with local tenant protection laws can be significant.
How to Serve the Notice Correctly
Under California Code of Civil Procedure § 1162, there's a required order of service methods. Email does not satisfy the legal service requirements.
Service must be attempted in this order:
A. Personal service — hand the notice directly to the tenant
B. Substituted service — if the tenant isn't home, leave a copy with a person of suitable age and discretion at the tenant's residence or usual place of business, and mail a copy to the premises
C. Post and mail — only if the tenant's residence or usual place of business cannot be ascertained, or no person of suitable age and discretion can be found there: post a copy in a conspicuous place on the premises and mail a copy
D. Certified or registered mail — an alternative to A/B/C, but requires additional time before you can file a legal action: 5 extra days if served in California, 10 days for another state, 20 days if outside the US
If you shortcut this and serve by email only, your notice doesn't start the clock — and an unlawful detainer filing based on it will likely be challenged.
The Form: C.A.R. Form NTT (Revised 3/24)
The California Association of REALTORS® Notice of Termination of Tenancy form (NTT, Revised March 2024) is the standard form for periodic tenancies. The form has you make one key determination upfront:
Is the property or tenancy covered by AB 1482? If yes, complete paragraph 2. If no, complete paragraph 3. Never complete both.
For covered properties (paragraph 2), you check the applicable no-fault reason and note the relocation assistance being provided. For non-covered properties (paragraph 3), you select the applicable notice period based on tenancy length.
The form includes a proof of service section that documents how and when the notice was served — keep a completed copy for your records.
What This Means If You're Selling a Property With Tenants
If you're selling a property with a tenant in place and the buyer intends to occupy it, there's a third-party timeline you need to coordinate around. Under certain conditions, you can issue a 30-day notice when the property is in escrow and the buyer is a natural person who intends to occupy the premises for at least one year — but the conditions are specific: escrow must have been opened within the prior 120 days, and the tenant cannot have previously received a termination notice.
What you need to know before buying a property with an existing ADU covers the buyer-side analysis in detail, including how existing tenancies affect financing, appraisal, and deal structure. For sellers, the tenant's occupancy status — and whether the right termination notices were ever served — is part of the disclosure picture.
In Long Beach's current buyer's market, where multi-unit properties are sitting longer than they have in years, sellers who understand their tenant situation — and have a clean paper trail on any past notices — are closing faster than those who don't.
Bottom Line
If you own rental property with an ADU in Orange County or LA County in 2026, the framework for ending a tenancy looks like this:
Determine coverage: Is your property covered by AB 1482 or exempt? (The ADU-on-owner-occupied-SFR exemption is the most commonly missed one)
Identify the reason: No-fault requires a specific allowable reason if covered; a 60-day notice with the reason stated
Calculate notice: 30 or 60 days depending on tenancy length; 60 days for all no-fault covered terminations
Pay relocation assistance: One month's rent, either waived from final month or paid within 15 days — mandatory for covered no-fault terminations
Serve correctly: In writing, via the legally required method — personal, substituted, or post and mail in that order
File with LAHD within 3 business days: Required for all City of LA terminations
There are substantial penalties for getting this wrong. If you're uncertain whether your property is covered, whether the right exemption notices were ever served, or how a local ordinance affects your situation, consult a qualified California real estate attorney before you serve anything.
