The Three Types of 3-Day Notices Under CCP §1161

1. 3-Day Notice to Pay Rent or Quit — CCP §1161(2)

The most common notice in commercial eviction. Used when the tenant has failed to pay rent. The notice must demand that the tenant either pay the total unpaid rent or surrender possession of the premises within 3 calendar days (excluding weekends and court holidays).

Required elements under CCP §1161(2):
  • The exact total amount of rent owed (not an approximation)
  • The specific rental period(s) for which rent is owed
  • The name, telephone number, and address of the person to whom rent may be paid (or the account number and name of financial institution if payment by deposit)
  • A demand for payment OR surrender of possession within 3 days

The Exact Amount Rule — Most Common Fatal Defect

California courts strictly enforce the requirement that the 3-day notice state the exact amount of rent owed. Overstatement of the amount — even by a dollar — renders the notice void and requires starting over. Common mistakes:

  • Including late fees as "rent" when the lease does not define them as rent
  • Adding CAM/operating expenses not defined as "rent" in the lease
  • Failing to credit a partial payment received after the default date
  • Including rent for future months not yet due
⚠️ Warning: If you are unsure whether a specific charge qualifies as "rent" under the lease, consult an attorney before including it in the notice. The safest approach is to include only base rent that is unambiguously unpaid.

2. 3-Day Notice to Perform Covenant or Quit — CCP §1161(3)

Used for curable, non-monetary breaches of the lease: unauthorized subletting, operating outside permitted use, property damage, failure to maintain required insurance, or other lease covenant violations. The tenant has 3 days to cure the violation or vacate.

The notice must identify the specific covenant breached and describe the required cure with sufficient specificity that the tenant can comply. Vague notices ("you are in violation of your lease") are legally insufficient.

3. 3-Day Unconditional Notice to Quit — CCP §1161(4)

Used for incurable breaches where no cure is possible or appropriate: maintaining a nuisance, committing waste, using the premises for illegal activities, or when the tenant has already been served two prior notices for the same breach and continues violating. This notice gives the tenant 3 days to vacate with no option to cure.

Using an unconditional notice for a curable breach is a legal error that may result in dismissal. Courts will examine whether the alleged breach truly falls into the incurable category.

Service of Notice — CCP §1162

A properly drafted notice that is improperly served is just as fatal as a defective notice. California Code of Civil Procedure §1162 specifies three valid methods of service, in order of preference:

Method 1: Personal Service (Preferred)

Deliver the notice directly to the tenant (or authorized agent) in person. For a corporate commercial tenant, deliver to an officer, general agent, or person authorized to accept service. Personal service is the most defensible and starts the 3-day period immediately.

Method 2: Substituted Service

If the tenant or authorized agent is not present at the place of business, leave the notice with a person of suitable age and discretion found at the place of business, AND mail a copy to the tenant at the place of business. Both the in-person delivery and mailing must occur on the same day.

Method 3: Post and Mail

If no person of suitable age is found at the place of business after reasonable attempts: post a copy conspicuously on the main entry AND mail a copy to the tenant. This method adds 5 days to the notice period — the landlord cannot file the UD complaint until 8 days (3 + 5) after the mailing date.

⚠️ Critical: Photograph the posted notice immediately after posting. Courts frequently require evidence that the notice was conspicuously posted. The inability to prove proper posting can result in dismissal.

Proof of Service

Always complete a written Proof of Service form documenting the date, time, method, and name of the person who served the notice. The proof of service is attached to the UD complaint and is critical evidence. Use a professional process server for defensibility, especially in high-stakes commercial evictions.

CCP §1161 — Frequently Asked Questions

No. Under CCP §1161 and CCP §12a, weekends (Saturday and Sunday) and judicial holidays are excluded from the 3-day count. The period begins the day after service. If the third day falls on a weekend or holiday, the period extends to the next court day. Example: Notice served Tuesday → Period runs Wednesday, Thursday, Friday = expires at midnight Friday. If served Thursday → Period runs Friday, Monday, Tuesday (skips weekend).
If the landlord accepts a partial payment, this typically constitutes waiver of the notice and forfeits the right to file the UD based on that notice. The landlord would need to serve a new notice demanding the remaining balance. If the landlord refuses the partial payment and the tenant tenders it, the situation is complex — consult an attorney before refusing any payment after a notice is served.
Only if your lease expressly defines CAM charges as "rent" or "additional rent." Many commercial leases do include CAM, insurance, and taxes as "additional rent," which means they can be included in the notice amount. However, if the lease treats them as separate obligations, including them in the notice amount will likely overstate the "rent" owed and invalidate the notice. Review the lease definition of "rent" carefully before including any amount beyond base rent.
Yes. CCP §1161 applies to all commercial tenancies in California, including month-to-month arrangements. However, to terminate a month-to-month commercial tenancy (as opposed to evicting for non-payment), a separate 30-day notice of termination may be required. The 3-day notice is for cure or quit — it does not itself terminate the tenancy; it is the predicate for filing a UD complaint if the tenant doesn't comply.
