If you own a rental property in Los Angeles and serve the wrong notice period, you do not just slow your case down. You hand the tenant a complete defense and restart the entire timeline. Most California tenancies end on a 30-day or 60-day notice, but three specific situations require a full 90 days, and getting that distinction wrong is one of the most expensive mistakes a property owner can make. Borna Houman Law advises landlords across Los Angeles County on which notice the law actually requires.
Key Takeaway: A 90-day notice to vacate is required in California in three situations: terminating a Section 8 or subsidized tenancy, removing a bona fide tenant after a foreclosure under Civil Code § 1161b, and imposing a cumulative rent increase above 10% in a 12-month period under Civil Code § 827(b). For standard market-rate tenancies, a 30-day or 60-day notice under Civil Code § 1946.1 applies instead.
When Does a California Landlord Have to Give a 90-Day Notice?
A 90-day notice is the exception, not the rule, and it applies only to a narrow set of tenancies. The three triggers are subsidized housing, post-foreclosure tenancies, and large rent increases. Each rests on a different statute, and each carries its own procedural traps.
Property owners who manage a mixed portfolio run into trouble when they apply one notice period across every unit. A market-rate duplex and a Section 8 single-family rental do not follow the same rules. The notice period is dictated by the tenancy type, not by the owner’s preference.
| Situation | Required Notice | Governing Authority |
|---|---|---|
| Section 8 / subsidized tenancy termination | 90 days, just cause required | HUD HAP contract rules; Civil Code § 1946.2 |
| Tenant remaining after foreclosure | 90 days | Civil Code § 1161b; federal PTFA |
| Cumulative rent increase over 10% in 12 months | 90 days | Civil Code § 827(b) |
| No-fault termination, tenancy ≥ 1 year | 60 days | Civil Code § 1946.1 |
| No-fault termination, tenancy < 1 year | 30 days | Civil Code § 1946.1 |
How Does the 90-Day Notice Work for Section 8 Tenancies?
To terminate a Section 8 tenancy in California, a landlord generally must serve a 90-day notice and state a just cause for the termination. The federal Housing Assistance Payments contract overrides the shorter state notice periods that apply to market-rate units.
The notice must identify the specific ground for termination and cannot be a simple no-fault “move out” demand once the tenant has been in place. A Section 8 landlord who serves a 60-day no-cause notice, as they might for a market-rate tenant, will lose the unlawful detainer.
In our experience, the most common Section 8 error is failing to coordinate the termination with the housing authority. The Public Housing Authority administering the voucher usually must receive a copy of the notice, and skipping that step gives the tenant grounds to challenge service. We confirm the HAP contract terms before any notice goes out.
What Notice Is Required After a Foreclosure in California?
A new owner who takes title to an occupied rental through foreclosure must give a bona fide tenant at least 90 days’ written notice before filing for possession under California Civil Code § 1161b. This protects tenants who had nothing to do with the former owner’s default.
The 90-day floor comes from both state law and the federal Protecting Tenants at Foreclosure Act. A “bona fide” tenant is one whose lease resulted from an arm’s-length transaction at market rent, which excludes the former owner, their child, or their spouse remaining in the home.
If a fixed-term lease predates the foreclosure, the buyer may have to honor the remaining term unless they intend to occupy the unit as a primary residence. Investors who buy at trustee sales often assume they can clear the property in 30 days, and that assumption produces dismissed cases. Owners navigating these acquisitions should understand the firm’s work on foreclosure-related property disputes and litigation before serving any notice.
Getting this wrong restarts the clock. Borna Houman Law reviews notices, files unlawful detainers, and defends habitability claims for Los Angeles property owners from our office at 2530 Wilshire Blvd, Santa Monica. Call (888) 42-BORNA to schedule a confidential consultation.
When Does a Rent Increase Require 90 Days’ Notice?
A California landlord must give 90 days’ written notice before any rent increase that, combined with other increases over the prior 12 months, exceeds 10% under California Civil Code § 827(b). An increase of 10% or less requires only 30 days’ notice.
This is a cumulative calculation, not a single-increase test. A landlord who raised rent 6% in March and wants another 5% in October has crossed the 10% threshold for the 12-month window and now owes the 90-day notice for the second increase.
For units covered by the Tenant Protection Act, the statewide cap separately limits annual increases to 5% plus regional CPI, with a 10% hard ceiling. The 90-day notice rule governs the timing of any compliant increase, not whether the increase itself is allowed. Owners managing increases should review our guide to AB 1482 exemptions for California landlords to confirm whether their property is even subject to the cap.
How Should Landlords Serve a 90-Day Notice Correctly?
Service of a 90-day notice must follow Code of Civil Procedure § 1162, which authorizes personal delivery, substituted service with mailing, or posting and mailing. Defective service is the single most common reason an otherwise valid notice fails.
The 90-day count begins the day after service is complete, and for posting-and-mailing the law adds time for mailing. Counting the period wrong by even one day can void the notice. We calendar each notice with the mailing extension built in.
A landlord should preserve proof of service in the form of a signed proof, photographs of posting, and certified mail receipts. When the case reaches an unlawful detainer trial, the proof of service is often the first document the judge examines. For the broader sequence after the notice expires, see our overview of the California eviction process for landlords.
What Happens If a Landlord Serves the Wrong Notice?
Serving a 30-day or 60-day notice where the law required 90 days is fatal to the unlawful detainer, and the court will dismiss the case. The landlord must then start over with a corrected notice and absorb both the lost time and the filing costs.
The reverse error also matters. Serving 90 days when only 30 were required gives the tenant a longer free runway than necessary, which is a costly gift on a premium Westside unit where holdover rent can exceed several thousand dollars a month.
California courts apply notice requirements strictly because eviction is a summary proceeding that moves fast in exchange for procedural precision. The most common mistake we see is an owner copying a notice from an online template that does not match their tenancy type. The template is rarely the problem; matching it to the correct statute is.
Frequently Asked Questions About 90-Day Notices in California
Do all California tenants get a 90-day notice?
No. A 90-day notice applies only to Section 8 or subsidized tenancies, post-foreclosure tenancies under Civil Code § 1161b, and rent increases above 10% under Civil Code § 827(b). Standard no-fault terminations use a 30-day or 60-day notice under Civil Code § 1946.1.
Does a 90-day notice still require just cause?
For a Section 8 termination and for most tenancies covered by the Tenant Protection Act, yes. The landlord must state a qualifying just cause under Civil Code § 1946.2, and the notice must identify the specific ground.
Can a landlord raise rent and require a 90-day notice at the same time?
Yes. If the cumulative increase over 12 months exceeds 10%, the rent increase itself requires 90 days’ written notice under Civil Code § 827(b), even though it is not a termination.
How long does a buyer after foreclosure have to wait?
A foreclosure buyer must give a bona fide tenant at least 90 days’ written notice under Civil Code § 1161b before seeking possession. A pre-existing fixed-term lease may extend that period further.
What makes a 90-day notice invalid?
Improper service under Code of Civil Procedure § 1162, an incorrect day count, a missing just-cause statement where one is required, or failure to copy the housing authority on a Section 8 termination. Any of these can void the notice and force the landlord to restart.

Does a Section 8 tenancy require a 90-day notice in California?
In most terminations, yes. An owner ending a Housing Choice Voucher tenancy must give the tenant written notice of termination, and the owner must give the public housing authority that administers the voucher a copy of that same notice. The period that controls is the longest period required by any source that applies to the tenancy, which means a 90-day period controls whenever the lease, the Housing Assistance Payments contract, federal regulation, or California law requires 90 days.
The grounds for terminating a Housing Choice Voucher tenancy, and the notice the owner must give, are governed by the Housing Assistance Payments contract between the owner and the housing authority and by 24 C.F.R. Part 982. Under those federal rules the owner must state the grounds for termination in the notice to the tenant, and the owner must give the housing authority a copy of any notice of termination given to the tenant.
California notice periods run in parallel with the federal rules rather than replacing them. A 30-day, 60-day, or 90-day period under California law applies on its own terms, and where a California period and a federal or contractual period both apply to the same termination, the longest applicable period controls. A voucher tenancy that is covered by the Tenant Protection Act also requires the owner to state a qualifying just cause under Civil Code section 1946.2.
The practical sequence for an owner is short. Confirm the notice period required by the lease, the Housing Assistance Payments contract, federal regulation, and California law, then use the longest of them. State the ground for termination in the notice. Serve the tenant, and serve the housing authority with a copy at the same time. A voucher tenancy is not a no-cause month-to-month tenancy, and treating it as one is how these cases get dismissed.
