The Riverside County eviction process runs through the Superior Court as an unlawful detainer lawsuit: serve the correct written notice, wait out the notice period, file the case at the courthouse that covers the property, have the tenant served by a neutral party, and then either take a default judgment or go to trial before the Riverside County Sheriff enforces the lockout. California treats these cases as summary proceedings, so they move faster than ordinary civil suits, but the speed comes with strict rules. A single misstep on the notice or the paperwork can force you to start over.
Grounds You Can Evict For
California Code of Civil Procedure Section 1161 sets out the reasons a tenant’s continued occupancy becomes unlawful: failing to pay rent, violating a material lease term, causing serious damage, maintaining a nuisance, or using the unit for illegal activity.1California Legislative Information. California Code of Civil Procedure 1159-1179a A tenancy also ends when the lease term runs out and the tenant stays without permission.
For most residential rentals, the California Tenant Protection Act (AB 1482) requires a qualifying reason before you can end a tenancy. The law splits allowable evictions into “at-fault” reasons (nonpayment, lease violations, nuisance, criminal conduct) and “no-fault” reasons (owner move-in, substantial renovation requiring the unit to be vacant, or withdrawing the unit from the rental market).2State of California – Department of Justice – Office of the Attorney General. Landlord-Tenant Issues
Not every property is covered. Single-family homes are generally exempt if the owner has given written notice of the exemption, and units built within the last 15 years fall outside the law. Confirm your coverage status before you choose a notice type, because the wrong notice or missing just-cause language will sink the case.
If you’re pursuing a no-fault eviction on a covered property, you owe the tenant relocation assistance equal to one month’s rent, paid within 15 calendar days of serving the termination notice. The alternative is waiving the tenant’s final month of rent, and the notice itself has to state which method you chose.3California Legislative Information. California Civil Code 1946.2 Skip this and the tenant has an immediate defense.
The Notice That Has to Come First
No Riverside court will hear an eviction until you have served the correct written notice and let it expire. The right notice depends on why you’re evicting:
- A 3-Day Notice to Pay Rent or Quit is used for unpaid rent. It has to state the exact amount owed, who to pay, and how. Weekends and court holidays don’t count toward the three days.
- A 3-Day Notice to Perform Covenants or Quit is used for curable lease violations, such as an unauthorized pet or occupant. It must describe the specific violation.
- A 3-Day Notice to Quit is used for violations that can’t be cured: illegal activity, serious nuisance, or subletting in violation of the lease. No chance to fix it is required.
- A 30-Day or 60-Day Notice to Quit ends a month-to-month tenancy. Tenants under a year get 30 days; tenants of a year or more get 60.4California Courts | Self Help Guide. Choose the Right Type of Eviction Notice
A defective notice is the single most common reason evictions fail. If the rent figure is off by a few dollars, or the notice goes to the wrong person, or weekends get counted toward a three-day period, the court will dismiss the case and you’ll re-serve and refile from the beginning.
Filing the Unlawful Detainer
Once the notice period expires and the tenant hasn’t cured or moved out, you file the lawsuit. The core Judicial Council forms are the Summons (SUM-100), which notifies the tenant a case has been filed;5California Courts | Self Help Guide. Summons SUM-100 the Complaint—Unlawful Detainer (UD-100), which lays out the property address, rent amount, notice type, and date of service;6California Courts. Complaint—Unlawful Detainer UD-100 and the Civil Case Cover Sheet (CM-010).7California Courts | Self Help Guide. Civil Case Cover Sheet CM-010
Every detail matters. The rent figure has to match the lease and the notice. The property description has to be accurate. The complaint also asks whether the property is subject to rent control or AB 1482, and an error there hands the tenant a defense.
Filing Fees
Riverside County charges more than the statewide baseline because of a local courthouse construction surcharge. Fees turn on how much you claim the tenant owes beyond possession:
- Up to $10,000 in damages: $270
- $10,001 to $35,000: $410
- Over $35,000: $4508Superior Court of California, County of Riverside. Fee Schedule
Most residential cases land in the first two tiers. A tenant who responds pays a filing fee too, ranging from $255 to $450 on the same thresholds.
Which Courthouse
Riverside County handles civil matters at several branches, including the Riverside Historic Courthouse, the Southwest Justice Center in Murrieta, and courthouses in Moreno Valley, Corona, and Palm Springs.9Superior Court of California, County of Riverside. Civil The correct location depends on where the property sits. Call the clerk’s office if you aren’t sure; filing at the wrong branch causes delays.
Serving the Tenant
After filing, the Summons and Complaint have to be formally delivered to the tenant, and you can’t do this yourself. A neutral third party (a registered process server or the Riverside County Sheriff) has to handle it. The preferred method is personal service, handing the papers directly to the tenant. If the tenant can’t be found after reasonable attempts, California law allows substituted service or, as a last resort, posting the papers on the door combined with mailing a copy.
Whoever serves the papers completes and signs a Proof of Service, which then gets filed with the court. Without it the case stalls. The method of service also sets the tenant’s deadline to respond, so this step drives the rest of the timeline.
If the Tenant Doesn’t Respond
A personally served tenant has 10 court days, excluding weekends and court holidays, to file a written response. Substituted service or posting extends that to 20 days.10California Legislative Information. California Code of Civil Procedure 1167
If no response comes in, you can request a default judgment the next day. That means filing a Request for Court Judgment (CIV-100), a Declaration for Default Judgment by Court (UD-116), a proposed Judgment—Unlawful Detainer (UD-110), and a Writ of Execution (EJ-130). Unpaid-rent cases also need a Verification Regarding Rental Assistance (UD-120).11California Courts. Ask for a Default Judgment Once the judge signs, you take the writ to the sheriff. Default is the fastest path to possession, and many tenants leave without responding.
If the Tenant Files an Answer
When the tenant files an Answer (UD-105), the case moves toward trial. You submit a Request to Set Case for Trial (UD-150) to get a hearing date.12California Courts | Self Help Guide. Request/Counter-Request to Set Case for Trial—Unlawful Detainer UD-150 California law directs the court to schedule trial within 20 days of that request.13California Legislative Information. California Code of Civil Procedure 1170.5 Riverside’s calendar can push that slightly, but unlawful detainers still move much faster than ordinary civil cases.
At trial, a judge or commissioner hears testimony and reviews the lease, the notice with its proof of service, and the payment records. Bring everything relevant: the original lease, the notice, bank statements or rent ledgers, photos of any damage, and written communications with the tenant. If you win, the court issues a Judgment for Possession and can also award past-due rent plus court costs.
Defenses You Should Expect
Any one of these defenses can derail an otherwise solid case:
- Defective notice: wrong rent amount, improper service, or missing required information. This is the defense that succeeds most often, and it is entirely preventable.
- Uninhabitable conditions: the tenant claims you failed to maintain the property, pointing to broken plumbing, no heat, mold, or pest problems.
- Retaliation: the tenant argues the case was filed in response to a code complaint, a repair request, or a call for emergency services.
- Discrimination: the tenant alleges the eviction is based on race, sex, religion, disability, family status, or another protected characteristic.
- Acceptance of rent after the notice expired, which can waive the right to evict.14California Courts | Self Help Guide. Eviction Defenses
Habitability catches landlords off guard more than the others. A tenant behind on rent can still win if the unit has serious unaddressed repair issues, because California ties the duty to pay rent to the landlord’s duty to maintain the property. Document the condition of the unit before you file.
The Sheriff Lockout
After judgment, you apply for a Writ of Possession (form EJ-130), which authorizes the Riverside County Sheriff’s Department to enforce the eviction.15Judicial Council of California. Writ of Execution EJ-130 A deputy serves a Notice to Vacate at the property giving the tenant five days to leave.16California Courts. Ask for More Time to Move If the tenant is still there after five days, the deputy returns to physically remove the occupants and oversee a lock change. The tenant can ask the court for a brief stay, but judges grant those sparingly and only for exceptional hardship.
What You Cannot Do
No matter how far behind the tenant is, you cannot skip the court process. Changing the locks, shutting off utilities, removing belongings, or taking doors off the hinges all violate California Civil Code Section 789.3. The penalty is actual damages plus up to $100 per day for every day the violation continues, with a minimum of $250 per incident, and courts treat repeat violations as separate offenses. A self-help eviction also poisons your unlawful detainer case. Use the court process; the wait is shorter than the fallout.
After the Tenant Is Out
Once the tenant vacates, you have 21 calendar days to either return the security deposit in full or provide an itemized statement of every deduction, with receipts or estimates for repairs and cleaning. Deductions must be for actual damage beyond normal wear and tear, unpaid rent, or cleaning to restore the unit. Miss the deadline or withhold in bad faith and a court can order you to pay the tenant up to twice the deposit amount as a penalty, on top of actual damages.17California Legislative Information. California Civil Code 1950.5
If the tenant left belongings behind, you can’t just throw them out. Civil Code Section 1983 requires a written notice to the tenant’s last known address describing the property, where it can be picked up, and a deadline of at least 15 days if hand-delivered or 18 days if mailed.18California Legislative Information. California Civil Code 1983 Store the items safely during the waiting period. After the deadline, items worth $700 or less at resale can be kept, donated, or discarded; items worth more must be sold at public auction, with the proceeds minus storage costs held for the former tenant.
Active-Duty Military Tenants
If your tenant is an active-duty servicemember, the Servicemembers Civil Relief Act adds federal rules on top of California’s. You can’t evict a servicemember or their dependents without a court order when the monthly rent is $10,542.60 or less (the 2026 threshold, adjusted for inflation each year).19Office of the Law Revision Counsel. 50 USC 3951 – Evictions and Distress If military service has materially affected the servicemember’s ability to pay, the court can pause the eviction for 90 days or longer and adjust the lease terms. Violating the SCRA is a federal misdemeanor carrying up to one year in jail, so verify military status through the Department of Defense database if you have any reason to suspect it.
