How to Fight an Eviction in San Diego County Tenant Rights After an Unlawful Detainer Summons

If you are a tenant living in San Diego County and you have received an Unlawful Detainer Summons you must act immediately. San Diego County is one of the most active counties in California for unlawful detainer filings. Thousands of San Diego County tenants face eviction proceedings every year across a vast and diverse rental market that stretches from the urban communities of downtown San Diego, Chula Vista, and National City to the suburban communities of El Cajon, Santee, Escondido, and Vista and the coastal communities of Oceanside, Carlsbad, and Encinitas. Understanding your rights and options after receiving an Unlawful Detainer Summons in San Diego County is critical to protecting yourself, your family, and your home.

Where Are San Diego County Unlawful Detainer Cases Filed?

Unlike Los Angeles County — which has eleven courthouse locations for unlawful detainer matters distributed across the county — all unlawful detainer cases in San Diego County must be filed in the Central Division of the San Diego Superior Court at the Hall of Justice located at 330 W. Broadway, Room 225, San Diego, CA 92101. CA

Hall of Justice — Central Division 330 West Broadway, Room 225 San Diego, CA 92101 Civil Business Office Phone: (619) 450-7276. Please note that the telephone lines are answered between the hours of 8:30 a.m. and 11:30 a.m..

Effective November 3, 2025, the unlawful detainer courtroom was relocated from the 5th floor, Department 501, to the 2nd floor, Department 201. CA All unlawful detainer hearings in San Diego County are presided over in Department 201 on the 2nd floor of the Hall of Justice.

This is the courthouse where your responsive pleading must be filed before your deadline expires regardless of where in San Diego County your rental property is located. Filing at any other courthouse location will result in your responsive pleading being rejected.

What is My Filing Deadline as a San Diego County Tenant?

Effective January 1, 2025, AB 2347 extended the deadline for tenants to respond to an Unlawful Detainer Summons throughout California from 5 court days to 10 court days. This extension applies in San Diego County as it does throughout the rest of California. AB 2347

If the Unlawful Detainer Summons was personally handed to you by a process server you must file your responsive pleading within 10 court days from the date service was effected. Day 1 of this deadline begins the first court day after the date the Summons was personally handed to you.

If the Unlawful Detainer Summons was served by substituted service — meaning the documents were left with another adult at your residence or place of work rather than personally handed to you — you have 10 court days plus an additional 10 calendar days from the date the documents were left with the other adult. CCP § 415.20

If the Unlawful Detainer Summons was served by posting pursuant to a Court Order — meaning it was posted to the entrance of your residence and mailed to you — you have 10 court days plus an additional 10 calendar days from the date the Summons was posted and mailed. CCP § 415.45

Court days do not include Saturdays, Sundays, or court holidays. Call our office immediately at (657) 510-6534 to confirm your specific filing deadline.

What Types of Responsive Pleadings Can a San Diego County Tenant File?

A San Diego County tenant who has received an Unlawful Detainer Summons may file any of the following responsive pleadings with the Court before their filing deadline expires:

Answer to Unlawful Detainer Complaint (Judicial Council Form UD-105) — The most commonly filed responsive pleading. An Answer admits or denies the allegations of the Unlawful Detainer Complaint and raises any and all affirmative defenses available to the tenant. Filing an Answer as the initial responsive pleading typically results in a trial being scheduled within approximately 20 days of the landlord filing a Request to Set Case for Trial. CCP § 1170.5

Motion to Quash — Challenges the validity of service of the Unlawful Detainer Summons. Appropriate where service was not effected in accordance with the California Code of Civil Procedure. A hearing on a Motion to Quash is held between 3 and 7 days after the Motion is filed. Prior to filing the Motion the tenant must contact the Civil Business Office at the Hall of Justice to reserve a hearing date. CCP § 418.10

Motion to Strike — A formal challenge to specific portions of the Unlawful Detainer Complaint that are improper or not legally permissible. A hearing on a Motion to Strike is held between 5 and 7 days after the Motion is filed. Prior to filing the Motion the tenant must contact the Civil Business Office to reserve a hearing date. AB 2347

Motion for Demurrer — Challenges the legal sufficiency of the Unlawful Detainer Complaint itself. Appropriate where the Complaint contains fundamental legal defects such as a Three Day Notice that demanded an incorrect amount of rent or that was not served in accordance with the California Code of Civil Procedure. A hearing on a Motion for Demurrer is held within 7 days of the date the Motion is filed. Prior to filing the Motion the tenant must contact the Civil Business Office to reserve a hearing date. CCP § 1170

As a general principle, filing a Motion to Quash, Motion to Strike, or Motion for Demurrer as the initial responsive pleading rather than an Answer to the Unlawful Detainer Complaint extends the timeline of the eviction proceedings by approximately one additional month.

What Affirmative Defenses Are Available to San Diego County Tenants?

A San Diego County tenant who files an Answer to the Unlawful Detainer Complaint may raise any affirmative defenses that are supported by the facts and circumstances of their case. The following are among the most commonly raised affirmative defenses in San Diego County unlawful detainer proceedings:

— The landlord breached the Implied Warranty of Habitability by failing to maintain the property in a habitable condition. CC § 1941

— The Three Day Notice upon which the Unlawful Detainer Complaint is based demanded an incorrect amount of rent, included impermissible charges such as late fees or utilities, or was otherwise legally defective. CCP § 1161

— The eviction is retaliatory — meaning the landlord filed the Unlawful Detainer Complaint in response to the tenant exercising a legally protected right such as requesting repairs, reporting habitability issues to a government agency, or asserting rights under California law. CC § 1942.5

— The eviction violates the California Tenant Protection Act of 2019 (AB 1482) because the landlord failed to have a valid just cause for terminating the tenancy after the tenant had occupied the unit for 12 months or longer. CC § 1946.2

— The eviction violates a local rent control or just cause eviction ordinance applicable to the rental unit.

— The landlord accepted rent after serving the Three Day Notice, thereby waiving the right to terminate the tenancy based on that notice.

— The eviction is discriminatory in violation of the Fair Employment and Housing Act. Gov. Code § 12955

Important Tenant Protections Specific to San Diego County

San Diego County and several of its cities have enacted local tenant protection ordinances that may provide additional protections beyond those afforded by state law. San Diego County tenants should be aware of the following local protections that may apply to their specific tenancy.

City of San Diego Tenant Protection Ordinance — The City of San Diego has enacted a local tenant protection ordinance that provides just cause eviction protections for qualifying tenants within the City of San Diego. Tenants residing within the City of San Diego limits should verify whether this ordinance applies to their specific rental unit and tenancy as it may provide additional defenses in an unlawful detainer proceeding beyond those available under state law.

AB 1482 — California Tenant Protection Act of 2019 — AB 1482 applies to most residential rental units in San Diego County that were built more than 15 years ago and that do not otherwise fall within one of the statutory exemptions. In 2026 this means that most residential rental units built before 2011 are subject to AB 1482 protections. If AB 1482 applies to your tenancy and your landlord failed to have a valid just cause for terminating your tenancy before filing the Unlawful Detainer Complaint against you this may constitute a complete defense to the eviction. For a detailed discussion of AB 1482 and how it may apply to your specific tenancy please refer to our article California Tenant Protection Act AB 1482 — Does It Protect You From Eviction?

Do San Diego County Tenants Need to Pay a Court Filing Fee?

Yes. The Court will require payment of a filing fee at the time you submit your responsive pleading at the Hall of Justice. The amount of the filing fee depends on the amount of monetary damages the landlord is seeking in the Unlawful Detainer Complaint. If you are unable to afford the filing fee you may apply for a waiver by submitting a Request to Waive Court Fees (Form FW-001) and a completed Order on Court Fee Waiver (Form FW-003) together with your responsive pleading. San Diego County requires submission of both the FW-001 and the FW-003 forms for a complete fee waiver application.

Free Legal Assistance Available to San Diego County Tenants

The Legal Aid Society of San Diego operates a clinic at the Central Division of the San Diego Superior Court that offers free assistance to self-represented litigants by explaining landlord-tenant procedures and helping prepare forms. CA Tenants should check the Legal Aid Society of San Diego's website or contact them directly for current clinic schedules and eligibility requirements.

In addition, low-income parties may be eligible for free legal representation in unlawful detainer cases in the Central Division of the San Diego Superior Court through the Sargent Shriver Civil Counsel Act program.
