Eviction Services in Ontario, CA: Notices, Filings and Contested Cases

Ontario is one of the Inland Empire’s largest cities and employment centers, anchored by the airport and miles of distribution facilities. Its rentals include older apartment buildings and houses in the central city, condos near the Ontario Mills area, and thousands of new homes in Ontario Ranch to the south. 951 Evictions prepares and serves notices, files unlawful detainer cases and coordinates lockouts for Ontario owners and managers.

Call or text (951) 580-0388 to start a notice, or if a tenant has already filed a response to a case you began yourself.

Where Ontario Eviction Cases Are Filed

Ontario does not have a courthouse that takes eviction filings. Limited landlord-tenant cases for zip codes 91761, 91762 and 91764 are filed at the Fontana District courthouse (17780 Arrow Boulevard, Fontana, CA 92335), the San Bernardino Superior Court’s landlord-tenant location for the west valley since those cases were moved out of Rancho Cucamonga in 2014. The court’s Where Can I File list shows what each location accepts.

Filing location checked against the court’s published list in November 2026. Courts do reassign case types, so we confirm the venue before every filing.

When the Tenant Files an Answer

An answer means the case is contested, not lost. The landlord files a request to set the case for trial, and the court must set it within 20 days. Before trial, either side can ask for documents and written answers on a short deadline, and the tenant may demand a jury. Many contested cases in Fontana settle on the trial date with a written agreement that sets a move-out date and deals with the rent, enforceable as a judgment if the tenant does not go. We describe what to expect in The Tenant Filed an Answer to My Eviction in Ontario, CA: What Now?

Getting the 3-Day Notice Right

The notice has to state the precise rent due, the name, address and phone number of the person to pay, the days and hours payment can be made, and the method. It cannot include late fees. A notice that overstates the amount by even a small sum can lose the case. See How Do You Write a Valid 3-Day Notice in Ontario?

Ontario Ranch and the 15-Year Exemption

Housing built in the last 15 years is exempt from the state’s just-cause and rent-cap rules, which covers most of Ontario Ranch. Older apartments in the rest of the city are covered once a tenant has been in place 12 months. Ontario has no rent ordinance of its own.

How a Ontario Eviction Moves Forward

We prepare and serve the notice, file the complaint in Fontana when it expires, and have the summons served. The tenant has 10 court days to respond. If no answer is filed, we request a default judgment. If one is, the case is handled through the contested phase and trial. After judgment, the San Bernardino County Sheriff’s civil division posts a five-day notice to vacate and performs the lockout. Ontario’s police department does not enforce eviction judgments.

Ontario Eviction FAQ

I started the case myself and the tenant answered. Can you take over?

Yes. Bring the notice, proof of service, complaint and answer. The first thing we check is whether the notice will hold up at trial.

The tenant claims the unit needs repairs. Does that stop the eviction?

It is a defense the judge will consider. If the conditions are real and you knew about them, the rent owed may be reduced. Repair records are your best response.
