If you have just been served with a summons and complaint, understanding the California unlawful detainer timeline is the most important thing you can do right now. The California unlawful detainer timeline moves faster than almost any other civil court process in the state — and missing even one deadline can result in a default judgment and a sheriff showing up at your door within weeks.
Take a breath. You have time to act — but you need to act now.
What Is an Unlawful Detainer?
An unlawful detainer (UD) is a court lawsuit filed by a landlord to recover possession of a rental property. It is not the same as an eviction. Receiving a UD summons does not mean you have already lost your home.
Here is what the law requires before any landlord can physically remove you:
- The landlord must file and serve a lawsuit in Superior Court
- You must have the opportunity to respond and defend yourself
- The landlord must win a court judgment for possession
- A sheriff must serve a 5-day notice to vacate before executing any lockout
In other words, the process gives you rights and opportunities at every stage — but only if you use them. The timeline below shows exactly where those opportunities are.
The Full California Unlawful Detainer Timeline (Step-by-Step)
Step 1 — Day 0: Notice Served
Before a landlord can file a UD lawsuit, they must first serve a written notice. The type of notice depends on the reason for eviction:
- 3-Day Notice to Pay Rent or Quit — Most common. You have 3 days to pay all overdue rent or vacate.
- 3-Day Notice to Perform Covenant or Quit — For lease violations (e.g., unauthorized pets, subletting). You have 3 days to fix the violation or vacate.
- 3-Day Notice to Quit (Unconditional) — For serious violations like drug activity or repeated breaches. No option to cure — vacate within 3 days.
- 30-Day or 60-Day Notice to Vacate — For month-to-month tenancies. Tenants with less than 1 year of occupancy receive 30 days; more than 1 year receive 60 days.
- 90-Day Notice — Required in some federally subsidized housing situations.
Important: Under AB 1482 (California's statewide rent control law), landlords of covered units must have "just cause" to evict and must include the specific reason in the notice.
Step 2 — Notice Period Ends: UD Filed in Superior Court
If you do not comply with the notice (pay rent, cure the violation, or vacate), the landlord may file a UD lawsuit in the Superior Court of the county where the property is located.
The landlord files a Complaint (Judicial Council Form UD-100) and pays a filing fee. The court issues a Summons (Form SUM-130). These documents must then be served on you — the tenant.
Step 3 — Service of Summons and Complaint
The landlord must properly serve you with the UD summons and complaint before the clock on your response deadline starts. California law recognizes three methods:
- Personal service — The process server hands the documents directly to you
- Substituted service — Documents are left with a competent adult at your home or workplace, AND mailed to you (adds 10 extra days to your deadline)
- Service by mail (posting) — If personal and substituted service are not possible after multiple attempts, documents may be posted on the door and mailed (adds 10 extra days)
Step 4 — Response Deadline: 5 Court Days (CRITICAL)
This is the single most important deadline in the entire process.
Once you are properly served, you have 5 court days to file a written response with the court. If service was by substituted service or mail, you have 15 calendar days (the 5-day period plus 10 additional days).
Missing this deadline = automatic default judgment. The landlord can immediately request a default judgment for possession, and the sheriff will receive a Writ of Execution authorizing a lockout. You will have no further opportunity to present your case.
Step 5 — Trial: Set Within 20 Days of Answer
If you file a timely response, the court schedules a trial date — typically 20 days after the answer is filed, sometimes as few as 10 days. This is dramatically faster than ordinary civil litigation, which can take months or years.
At trial, both parties present evidence and testimony. The landlord bears the burden of proving their case. You have the opportunity to present defenses.
Step 6 — Judgment
If the landlord prevails at trial, the court issues a judgment for possession. If you win, the case is dismissed and you may recover costs.
A judgment against you also becomes a public court record that can appear in tenant screening reports.
Step 7 — Writ of Possession
After a judgment for possession, the landlord requests a Writ of Possession from the court clerk. The clerk issues the writ and delivers it to the county sheriff.
The sheriff serves you with a 5-day notice to vacate — this is your final opportunity to leave voluntarily before the lockout is executed.
Step 8 — Lockout
If you remain after the 5-day notice expires, the sheriff returns to physically execute the writ — changing locks and removing occupants. The landlord regains possession.
Total time from first notice to lockout: as few as 5–6 weeks in an uncontested case. With a timely response and active defense, the timeline typically extends to 2–4 months.
The 5-Court-Day Rule: A Deep Dive
Because this deadline is so consequential, let's be precise.
"Court days" means weekdays when the court is open. Saturdays, Sundays, and official court holidays do not count. California courts observe New Year's Day, MLK Jr. Day, Presidents' Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas — plus any days the court closes by local rule.
How to count your 5 days:
- Do not count the day you were served
- Count only days the Superior Court is open
- Your response must be filed and received by the court clerk before closing time on Day 5
Example: If you are personally served on a Monday, Day 1 is Tuesday. If there are no holidays, your deadline is the following Monday. If served on a Thursday before a 3-day weekend (Friday holiday + weekend), Day 1 is the following Tuesday — giving you until the following Monday.
Service method matters:
- Personal service → 5 court days
- Substituted service → 5 court days + 10 calendar days = typically 15 calendar days
- Service by mail (posting) → 5 court days + 10 calendar days = typically 15 calendar days
When in doubt about your exact deadline, contact the court clerk's office — they cannot give legal advice but can confirm court holidays and hours.
What to Include in Your UD Response (UD-105)
Your written response is filed on Judicial Council Form UD-105 (Answer — Unlawful Detainer). This form allows you to deny the landlord's claims and raise affirmative defenses — legal grounds that can reduce or eliminate the landlord's right to evict even if the underlying facts are accurate.
Common affirmative defenses in California UD cases include:
- Improper notice — The notice was defective in form, service, calculation of the cure period, or did not contain required disclosures
- Habitability (Warranty of Habitability) — The rental unit has serious health or safety defects that the landlord failed to repair; California courts recognize this as a complete or partial defense to eviction for nonpayment (Green v. Superior Court)
- Retaliatory eviction — The landlord is evicting in response to you exercising a legal right (requesting repairs, contacting a housing agency, organizing with other tenants) — CCP §1942.5 creates a rebuttable presumption of retaliation within 180 days of protected activity
- Discriminatory eviction — The eviction is motivated by race, color, religion, sex, national origin, disability, familial status, sexual orientation, gender identity, source of income, or other protected class (Fair Employment and Housing Act / Fair Housing Act)
- Acceptance of rent after notice — The landlord accepted rent after serving the notice to quit, which may waive the breach
- Waiver of breach — The landlord knew of the lease violation and previously accepted performance anyway
The UD-105 form also asks you to verify the allegations in the complaint and state the facts supporting each defense. Accuracy and completeness matter — courts take the pleadings seriously.
Requesting a Jury Trial
California tenants have the right to request a jury trial in a UD proceeding. The request must be filed along with the UD-105 response (or immediately after, with a jury fee deposit).
A jury trial typically adds 4–8 weeks or more to the timeline, since the court must schedule a jury panel, conduct voir dire, and allow time for trial preparation. This can be strategically significant if you need additional time to secure housing or resolve the underlying dispute.
Note that jury trial rights in UD cases involve specific procedural requirements — the jury fee must be deposited and the demand must be timely.
Discovery and Continuances
Even within the compressed UD timeline, California law provides tools to extend proceedings for legitimate purposes:
Discovery — You may serve written discovery requests (interrogatories, requests for production of documents) on the landlord. Responding to discovery takes time and can delay the trial date. Discovery is particularly useful when habitability or retaliatory eviction defenses are involved, because it allows you to obtain the landlord's maintenance records, repair logs, and communications.
Continuances — Either party may request a continuance (postponement of the trial date) for good cause. Good cause includes time needed to locate a witness, obtain documents, or address a medical emergency. Continuance requests require a formal motion filed with the court.
Both discovery and continuances require proper court filings — they do not happen automatically, and deadlines for requesting them are tight.

Frequently Asked Questions
What if I missed the 5-court-day deadline?
Act immediately. If a default judgment has been entered, you may file a Motion to Set Aside Default under California Code of Civil Procedure §473. This motion must typically be filed within 6 months of the default entry, and you must show mistake, inadvertence, surprise, or excusable neglect. Courts have discretion to grant relief — but the longer you wait, the harder it becomes. If a Writ of Possession has already been issued, the timeline is even more compressed.
Can I stop an eviction by paying rent?
It depends on the notice type. If you received a 3-Day Notice to Pay Rent or Quit, you can stop the eviction by paying the full amount stated in the notice within the 3-day period — and the landlord must accept the payment. Once the cure period expires and a UD has been filed, whether payment can stop the case depends on the landlord's agreement and the specific facts. For notices that do not allow a cure (unconditional quit notices, lease termination notices), payment alone does not stop the process.
Does a UD judgment go on my record?
Yes. California Superior Court records are public, and UD filings — even those that are dismissed — can appear in tenant screening reports. A judgment for possession typically remains in court records indefinitely and is frequently reported to tenant screening services, which can make it difficult to rent in the future. This is one reason why filing a timely response and seeking to resolve the case is so important.
Can my landlord lock me out without a court order?
No. Self-help eviction is illegal in California. Civil Code §789.3 prohibits landlords from changing locks, removing doors or windows, cutting off utilities, or otherwise forcing a tenant out without a court order and sheriff execution of a Writ of Possession. Landlords who violate this law are liable for actual damages, punitive damages up to $100 per day of violation, and attorney fees.
What about rental assistance programs?
Emergency Rental Assistance Program (ERAP) funding may be available in your county, depending on current program availability. Some programs can pay back rent directly to landlords and stop a pending eviction. Check with your county housing authority, local 211, or a housing counseling agency for current program status. If rental assistance is applied for and approved, courts may stay (pause) eviction proceedings in some circumstances.
