Alameda County Eviction Process: Notices, Lawsuit, and Lockout

The Alameda County eviction process runs through five stages: establish a legally valid reason, serve the correct written notice, file an unlawful detainer lawsuit in Superior Court if the tenant doesn’t comply, win a judgment, and have the Alameda County Sheriff perform the lockout. A clean case takes 30 to 45 days from the first notice to the day the sheriff changes the locks.¹ Contested cases in the county routinely run two to three months. Any mistake along the way — the wrong dollar amount on a notice, a missed disclosure, a skipped relocation payment — can get the entire case thrown out and send you back to the start.

You Need a Just Cause

Once a tenant has lived in the unit for 12 months, California’s Tenant Protection Act requires a landlord to have a valid reason to end the tenancy.² Alameda County goes further. The county’s own Just Cause for Eviction Ordinance covers all unincorporated areas, and cities inside the county — Oakland and Berkeley among them — enforce their own tenant protection laws that predate and exceed the state baseline.³ Where state and local rules overlap, whichever gives the tenant more protection controls.⁴

Valid grounds fall into two buckets. At-fault causes are things the tenant did: not paying rent, breaking a material lease term, creating a nuisance, using the property for illegal activity, or refusing lawful landlord access. No-fault causes are reasons unrelated to tenant conduct: an owner or close family member moving in, withdrawing the unit from the market under the Ellis Act, or a government-ordered vacancy. Local ordinances layer on protections. Oakland’s ordinance, for example, lists ten specific just causes and blocks owner move-in evictions against tenants who are 60 or older, disabled, or catastrophically ill.⁵ Check your city’s housing department before deciding what cause to proceed on.

No-Fault Evictions Require a Relocation Payment

If you’re ending a tenancy for a no-fault reason, state law requires you to either pay the tenant one month’s rent as relocation assistance or waive the final month’s rent. The payment has to be provided within 15 calendar days of serving the notice. Miss that window, or underpay, and the notice is void.

Oakland sets fixed amounts under its Uniform Relocation Ordinance that run well above the state floor:

Studio or one-bedroom: $8,106.68
Two-bedroom: $9,977.45
Three or more bedrooms: $12,315.92

Households with lower-income tenants, elderly or disabled tenants, or minor children get an additional $2,500 per unit on top of those figures.⁶ These numbers aren’t negotiable, and a tenant whose relocation payment was short or late has a defense that will likely end the case.

The Written Notice

Every eviction starts with a written notice. The type depends on why you’re ending the tenancy.

A 3-Day Notice to Pay Rent or Quit covers unpaid rent. The notice must state the exact amount owed and can only include past-due rent — no late fees, no utility charges, no other costs. If the demand is off by even a dollar, the notice is invalid.⁷
A 3-Day Notice to Cure or Quit is for fixable lease violations, such as an unauthorized pet. The tenant has three days to correct the problem or move out.
A 30-Day Notice to Quit applies to no-fault terminations when the tenant has been in place less than a year. A 60-Day Notice applies when all tenants have lived there for a year or more.

The three-day period excludes Saturdays, Sundays, and court holidays, so a “three-day” notice typically runs five or six calendar days.⁸

Alameda County Disclosure Requirements

In unincorporated Alameda County, you must send a copy of the eviction notice to the County Community Development Agency. Skipping that step gives the tenant an affirmative defense. The notice has to state the reason for termination and, for no-fault evictions, explain the tenant’s right to relocation assistance and the dollar amount being paid. For substantial-remodel evictions, the notice also needs to describe the planned work, give an estimated timeline, and inform the tenant of their right of first refusal to re-rent the unit when work is done.³

Oakland, Berkeley, and other cities with rent stabilization programs each require their own disclosure language about tenant rights under the local ordinance. The specifics vary. Confirm the current requirements with the relevant city housing department before serving anything.

How to Serve the Notice

California law lays out three service methods, in order of preference:

Personal delivery — handing the notice directly to the tenant. This is the cleanest and the hardest to challenge.
Substituted service — if the tenant isn’t at home or work, leaving the notice with a responsible adult (18 or older) at either location and mailing a copy to the same address.
Posting and mailing — only when the tenant can’t be found and no responsible adult is available. The notice is posted in a visible spot on the property and a copy is mailed.⁹

Jumping to posting without multiple documented attempts at personal delivery is an easy target for the tenant’s attorney. Whoever serves the notice completes a proof of service recording the method, date, and time. That document becomes critical evidence later.

Filing the Unlawful Detainer Lawsuit

If the tenant doesn’t comply within the notice period, you can file an unlawful detainer in Alameda County Superior Court. You’ll need:

Summons (SUM-100), which officially notifies the tenant of the lawsuit.¹⁰
Complaint — Unlawful Detainer (UD-100), which sets out the grounds for eviction, notice details, and the relief you’re asking for.
Civil Case Cover Sheet (CM-010).

Include every party’s name, the property address, and a clear account of how the tenant failed to comply. Attach the lease and the proof of service from the notice. A wrong name or a missing attachment can force an amended filing.

As of January 2026, filing fees depend on the amount in dispute: $240 for up to $10,000; $385 for $10,001 to $35,000; $435 for over $35,000. Most residential cases fall in the first two tiers.¹¹ Alameda County Superior Court accepts electronic filing through its eCourt system, or you can file in person at the Hayward Hall of Justice or the René C. Davidson Courthouse in Oakland.¹²

Serving the Lawsuit and the Tenant’s Response Window

Once the clerk issues the summons, a third party who isn’t involved in the case has to serve the summons and complaint on the tenant. You can’t do this yourself. Process servers typically charge between $50 and $150.

After personal service, the tenant has 10 court days to file a written response. Court days exclude weekends and court holidays, so the real calendar time is closer to two weeks.¹³ That window was extended in 2025 from the previous five-day deadline. If the tenant was served by substituted service rather than in person, service isn’t considered complete until 10 days after the mailing, and the tenant then gets 10 additional court days from that point.¹⁴

If the tenant doesn’t respond on time, you can request a default judgment for possession and the court grants the eviction without a trial. If they do file an answer, the case heads to trial.

Trial and Judgment

When a tenant answers, you file a Request to Set Case for Trial (Form UD-150). California law requires the court to set trial no later than 20 days after that request.¹⁵ Alameda County’s docket sometimes pushes that out, but the statute gives you grounds to press for a prompt hearing.

Either side can request a jury trial, though most unlawful detainer cases are tried to a judge. You carry the burden on every element: valid just cause, a properly drafted and served notice, the tenant’s failure to comply, and compliance with every local ordinance requirement. Win, and the court enters judgment for possession and can issue a writ of execution immediately.¹⁶

The Sheriff Lockout

A judgment doesn’t by itself remove the tenant. You deliver the writ of possession to the Alameda County Sheriff’s Office along with signed instruction forms (SER-001 and SER-001A) and a $180 fee.¹⁷ The sheriff posts a notice to vacate at the property. If the tenant hasn’t left by the end of the posting period, deputies return and perform a physical lockout, changing the locks.

Never try a self-help eviction — changing the locks yourself, shutting off utilities, or removing a tenant’s belongings. Doing that creates serious liability under California law, judgment or no judgment. The lockout goes through the sheriff.

How Long It Actually Takes

The California Courts estimate 30 to 45 days from the first notice to the lockout for a straightforward case. That assumes the notice is perfect, the tenant is easy to locate, and no defenses are raised. Contested cases in Alameda County commonly run two to three months, especially when tenants raise habitability claims or challenge the notice. Landlords who cut corners on the notice phase to save a few days almost always lose more time than they would have spent doing it right.

Defenses That Can Stop the Eviction

Tenants in Alameda County tend to know their defenses. The common ones:

Improper notice — wrong amount demanded, fees included that shouldn’t be, bad service, miscalculated dates. This is the most frequent defense and where most landlord mistakes happen.¹⁸
Uninhabitable conditions — unresolved problems like broken plumbing, mold, or lack of heat can block the eviction until the landlord fixes them.
Retaliation — California law presumes retaliation when the eviction notice comes within 180 days of certain protected tenant activities, such as reporting a code violation.
Discrimination — evictions motivated by race, disability, family status, sexual orientation, or any other protected characteristic violate state and federal fair housing law.
Local ordinance noncompliance — in Alameda County, that includes not notifying the County Community Development Agency, underpaying relocation assistance, or omitting mandatory disclosure language.³

When a defense succeeds, there’s no partial win. The case is dismissed, you fix the issue, and you start over with a new notice.

One Federal Step Before Default

Before the court will enter a default judgment against a tenant who hasn’t responded, you must file an affidavit stating whether the tenant is on active military duty. This is a federal requirement under the Servicemembers Civil Relief Act. If you can’t determine the tenant’s status, say so in the affidavit — the court may require a bond before letting the case proceed.¹⁹ For covered active-duty servicemembers, the SCRA also allows the court to stay the eviction for at least 90 days if military service has materially affected the tenant’s ability to pay rent.²⁰
