How Do You Write a Valid 3-Day Notice in Riverside? - 951 Evictions

Quick answer: A valid 3-day notice to pay rent or quit in Riverside, CA must state the exact rent owed — no late fees or other charges — cover only rent from the past 12 months, include contact and payment information, give the tenant three court days to pay, and carry the tenant-rights language required by SB 567. One drafting error can force you to restart the entire eviction.

What Every Riverside 3-Day Notice Must Contain

The 3-day notice to pay rent or quit is the legal foundation of a nonpayment eviction. If the notice is defective, everything built on it — the lawsuit, the judgment, the lockout — can collapse, and Riverside judges do scrutinize notices. A valid notice includes:

• The tenant’s name and the rental property’s address, matching the lease.
• The exact amount of rent due — rent only, with no late fees, interest, utilities, or other charges mixed in.
• The period the rent covers, limited to rent that came due within the past 12 months.
• Contact and payment information: the name, address, and phone number of the person who can accept payment, and when and how payment can be made.
• A clear demand to pay the stated amount or surrender possession within three court days.
• The tenant-rights language that SB 567 added to California notice requirements.
• The date and the landlord’s or agent’s signature.

The Exact-Amount Rule Is Where Most Notices Die

California law is unforgiving about the dollar figure. The notice must demand the precise rent owed — not an estimate, not a rounded number, and never a total padded with late fees, bounced-check charges, or utility reimbursements. A notice that overstates the rent, even slightly, is void, and a tenant’s attorney will find the error at trial. The 12-month lookback matters too: if a Riverside tenant has been behind for longer, the notice can only demand the portion that accrued in the last year. Pull the ledger, isolate pure rent, double-check the math, and keep the supporting records, because you may need to prove the figure in court.

Three Court Days, Not Three Calendar Days

The “3” in a 3-day notice means three court days: weekends and judicial holidays do not count. A notice served late in the week often does not expire until the middle of the following week, and holiday calendars stretch it further. Counting calendar days instead of court days is one of the most common reasons a landlord files the unlawful detainer too early — and an early filing is a defective filing. When in doubt, wait an extra court day before heading to the courthouse.

Serving the Notice and Proving You Served It

A perfectly drafted notice still fails if service is sloppy. California recognizes a hierarchy of service methods — personal delivery first, then fallback methods when the tenant cannot be reached directly — and the person serving should complete a proof of service that records who was served, how, where, and when. That proof becomes an exhibit in the unlawful detainer case, and a vague or inconsistent proof of service invites a challenge. Keep a copy of the signed notice and the proof together; the court will want both.

If the Notice Expires: Riverside’s Courthouse and Costs

When three court days pass with no payment, the next step is an unlawful detainer filed in Riverside County Superior Court, which requires electronic filing for civil and eviction cases. Cases from Riverside — along with Jurupa Valley, Eastvale, Norco, and the Corona area — are heard at the Riverside Historic Courthouse, 4050 Main St, Riverside 92501. Under the fee schedule effective January 1, 2026, a Riverside County unlawful detainer complaint costs $270 when the demand is $10,000 or less, which covers most nonpayment cases, plus $40 to issue the writ of possession. As of late 2026, an uncontested case runs roughly 5 to 9 weeks from notice to lockout; our guide to how long an eviction takes in Riverside County walks through the full timeline, and our Riverside eviction services page covers the local process end to end.

Frequently Asked Questions

Can I include late fees on a 3-day notice in Riverside?

No. A California 3-day notice to pay rent or quit may demand rent only. Late fees, interest, utility charges, and damage costs do not belong on the notice, and including them overstates the amount and voids it. You can still pursue those other charges separately — through the security deposit or a money claim — after possession is resolved.

Do weekends count toward the three days on the notice?

No. The three days are court days, so Saturdays, Sundays, and judicial holidays are excluded from the count. A notice served on a Friday will typically not expire until the following Wednesday, and holiday weeks push expiration even later. Filing the unlawful detainer before the final court day has fully run makes the lawsuit premature and vulnerable to dismissal.

Who is allowed to serve a 3-day notice in California?

The landlord, a property manager, or any adult may serve a 3-day notice — you do not need the sheriff for this step. What matters is using a legally recognized service method and completing an accurate proof of service. Many Riverside landlords have someone other than themselves serve the notice so the server can later testify as a neutral witness if service is disputed.

What if the tenant pays the full amount before the notice expires?

If the tenant pays the entire demanded rent within the three court days, the notice is satisfied and the tenancy continues; you cannot proceed with an eviction based on that notice. Partial payment is different — you may refuse it, or accept it and serve a fresh notice for the corrected balance. Accepting partial payment without a new notice can undermine the original one.
