Once an unlawful detainer complaint is served in California, the clock that matters is now 10 court days. That deadline comes from AB 2347, which rewrote Code of Civil Procedure Section 1167 effective January 1, 2025. Eviction timing is also only one of several rules that moved at once. If you want the fuller picture, we recommend our California landlord laws guide, where the rent cap, the deposit ceiling and the new 2026 duties sit together in one deep dive.
What CCP Section 1167 actually says
As amended by AB 2347 (Stats. 2024, ch. 512), effective January 1, 2025, California Code of Civil Procedure Section 1167 provides:
"...the defendant's response shall be filed within 10 days, excluding Saturdays and Sundays and other judicial holidays, after the complaint is served upon the defendant." (CCP Section 1167, subdivision (a))
"If service is completed by mail or in person through the Secretary of State's address confidentiality program ... the defendant shall have an additional five court days to file a response." (CCP Section 1167, subdivision (b))
So the working math is 10 court days from service, and 15 when service went out by mail or through the Safe at Home program. The full, current section text lives on the California Legislature's official site.
The impact of AB 2347 on unlawful detainer timelines in 2025
California’s Assembly Bill 2347 (AB 2347), effective January 1, 2025, changes key timelines in unlawful detainer (eviction) lawsuits. Among the most consequential updates: under revised Code of Civil Procedure Section 1167, defendants generally have more time to respond, commonly discussed as a shift from a five-day to a ten-court-day window to file an answer, depending on service method and case posture. Always confirm deadlines against current rules, your court’s local practices, and counsel.
This shift isn’t only “extra days.” It increases the burden on documentation, communication, and procedural discipline. Small mistakes in notices, service, filings, or calendaring can delay cases or weaken enforcement, another reason many owners lean on experienced property management and qualified legal counsel.
The impact on East Contra Costa landlords
East Contra Costa County (including communities like Antioch, Pittsburg, and Oakley) has a large share of single-family rentals and small landlords. When procedural rules tighten statewide, local owners still have to operationalize those rules in real filings, notices, and tenant communications. That makes clear internal processes, and accurate deadlines, especially important under AB 2347 and related unlawful detainer practice updates.
Our read, from the operator’s chair
Having run notices, service and move-outs across East Contra Costa rentals for over two decades, our honest take on AB 2347 is this: the extra court days rarely decide a case. What decides cases is the file - whether the notice template was current, whether proof of service was stamped and filed on time, whether every tenant contact was logged with its date and method. The new window did not make unlawful detainer harder for disciplined operators; it made sloppiness more expensive. Discipline, in practice, is the documentation that follows.
What has changed and why it matters
Doubling the response window does more than move a date. Ten court days is enough time for a tenant to find counsel, raise defenses, or negotiate, so cases that once ended in quick defaults are likelier to be contested on their facts, and the facts are whatever the paperwork shows.
The default path tightened at the same time. With proof of service now required on file before default is sought, a default judgment stops being a formality and becomes a checkpoint: if the service record is late, wrong, or missing, the fastest route through the case is the one that fails.
Motion practice moved too. Demurrers and motions to strike run on a compressed schedule under the new rules, and parties may respond orally or in writing; the exact motion and opposition deadlines depend on the court, so confirm them with counsel and your court’s local rules before calendaring.
Add the extra court days for mail service, and the pattern is consistent: every change rewards the owner who prepared before the dispute, and punishes the one reconstructing events afterward.
What owners should document (and track) today
To stay ahead of what the law now requires, owners should run a disciplined documentation protocol. The items to document and the systems to build:
1. Eviction-related forms and notices
- Update templates (for example, notice to pay or quit, cure, demand letters, termination notices) to reflect the new 10 court day response window where it applies to your unlawful detainer process, as confirmed with counsel.
- Clearly state response deadlines, including any extended days for mail service, to avoid ambiguity.
2. Proof of service and timing logs
- Maintain stamped copies and chain-of-custody records (date, time, method, server) for every notice or court paper served.
- File (or prepare to file) proof of service with the court at least three days before requesting default judgment.
3. Tenant communications
- Log all contacts (phone, email, text, in person), decisions, and tenant responses.
- Save copies of written correspondence and document the date and method of delivery.
4. Photographic and video evidence (if required locally or by lease)
- Document property condition before, during, and after tenancy (especially when ending tenancy or during inspection).
- Ideally include date-stamped photos or video of key areas: entryway, living spaces, damage, compliance with habitability standards.
5. Internal audit trail
- Track each procedural step in a case: when notices were drafted, served, when responses were due, when motions filed, hearings scheduled, oppositions filed.
- Use a calendar or case-management software to flag upcoming deadlines and avoid lapses.
6. Legal correspondence and court filings
- Keep complete versions of all pleadings, motions, oppositions, court orders, and notices of hearing.
- Retain proof of service on these filings, especially for motions and oppositions.
7. Continuing education and compliance review
- Periodically review local ordinances (cities or counties may impose stricter rules than state minimums).
- Train property management staff and agents on the new rules, timelines, and potential pitfalls.

Who runs this timeline: three honest paths
The rules above are the same whoever manages the property; what changes is who carries the calendar.
- Full-service management. For the single-family rentals we manage in Pittsburg, Antioch, Brentwood, Oakley, Bay Point and Concord, full-service management means the notices, service records, resident communications and dated documentation described above live in one property record, so if an unlawful detainer ever becomes necessary, the file your attorney needs already exists. Court proceedings themselves are always attorney work, on every path.
- Lease-only placement. With lease-only placement, we place a qualified resident and complete the move-in documentation; from that point the notices, timelines and records in this guide are yours to run.
- Self-managing. Entirely workable with discipline: the documentation checklist above is usable as-is, and pairing it with a deadline calendar and a landlord-tenant attorney covers the same ground a manager would.

Frequently asked questions
What is AB 2347 in relation to California unlawful detainer?
AB 2347 is state legislation that, effective January 1, 2025, adjusts certain procedural timelines in unlawful detainer actions, including how long a defendant may have to file an answer under CCP Section 1167 in many cases, often described as a shift from five days to ten court days, subject to service method and court rules.
What is unlawful detainer?
Unlawful detainer is the civil court process landlords use in California to regain possession of a rental after proper notice and filing, when permitted by law. It is sometimes called an eviction lawsuit in plain language.
What does “tenant response time” mean in this context?
In search results and practice, tenant response time often refers to how long a tenant has to respond after proper service in an unlawful detainer case, for example, time to file an answer after a summons and complaint. Exact deadlines depend on the facts and current statutes; confirm with counsel.
What should owners document after these 2025 timeline changes?
Many owners strengthen proof of service, notice templates, calendars, tenant communications logs, and court filing records so deadlines under AB 2347 and CCP Section 1167 are not missed.
What did AB 2347 change about California's eviction process?
AB 2347 extended the time a tenant has to respond to an unlawful detainer (eviction) lawsuit from 5 days to 10 court days under CCP Section 1167. The change took effect in 2025 and applies statewide to all residential unlawful detainer proceedings.
How many days does a tenant now have to respond to an eviction lawsuit in California?
Under AB 2347, tenants have 10 court days to file a written response to an unlawful detainer summons. Court days exclude weekends and court holidays, so the actual calendar time is typically 2 to 3 weeks. Previously, tenants had only 5 days.
How should California landlords adjust their eviction timeline for AB 2347?
Landlords and property managers should build the extended response window into their eviction timeline projections. Cases that previously moved to default judgment in under 2 weeks now require waiting at least 10 court days before proceeding. Accurate documentation of notice service dates is more important than ever.
Does AB 2347 apply to commercial evictions in California?
No. AB 2347 applies to residential unlawful detainer proceedings. Commercial evictions follow a different set of rules under the California Code of Civil Procedure and are not affected by this change.
Where can I read the official text of CCP Section 1167?
The official current text of Code of Civil Procedure Section 1167 is published by the California Legislature at leginfo.legislature.ca.gov. The section was last amended by AB 2347 (Stats. 2024, ch. 512), effective January 1, 2025, which set the 10-court-day response window quoted in this guide.
