Commercial Lease Rent Default Demand Letters: Business Tenants Before Eviction

Commercial Lease Rent Default Demand Letters

Pre-Eviction Rent Demands to Business Tenants in California

Commercial Rent Defaults and California Eviction Law

Pre-Eviction Demands to Business Tenants: When a business tenant stops paying rent, the lease usually controls the first steps: notice and cure periods, late charges, default interest, the security deposit, and who receives notice. Before filing an unlawful detainer against a business tenant, California requires a written notice under CCP § 1161. An attorney demand sent before or alongside that notice often resolves the arrears without a lawsuit.

Commercial leases only: This page covers leases of commercial property to business tenants. Residential rent owed by individual tenants is a consumer obligation, and I do not take landlord-side residential rent collection. If you are a tenant who received a rent demand, start with my tenant-side guidance on responding to a landlord's demand.

Types of Commercial Rent Notices

Notice Type	Purpose	Legal Effect
Attorney Demand Letter	Firm written demand for the lease balance, citing the lease sections	Creates a record and leverage; not by itself a basis for an unlawful detainer
Lease Default Notice	Notice and cure period required by the lease itself	May be a condition to declaring a default; follow the lease exactly
3-Day Notice to Pay Rent or Quit (CCP § 1161)	Statutory notice required before filing an unlawful detainer	Gives the tenant 3 days to pay or surrender possession

3-Day Notice to Pay Rent or Quit (CCP § 1161)

This is the statutory notice required before filing an unlawful detainer against a business tenant:

When Required: The tenant has failed to pay rent when due
Form Requirements: States the amount of rent owed, the period for which it is due, and a demand to pay within 3 days or surrender possession
Commercial Property Rules: CCP § 1161.1 has its own rules for how the amount is stated in a notice for commercial real property. Match the notice to the lease and to that section before serving it
Service: Served as CCP § 1162 allows (personal, substituted, or posting and mailing), unless the lease adds requirements
Timing: The 3-day period excludes Saturdays, Sundays, and court holidays

⚠️ Strict Compliance Required: A defective notice (wrong amount, wrong party, improper service) can defeat the unlawful detainer and cost weeks. Have the notice checked against the lease and the statute before it is served.

Read the Lease First

Notice clause: where and how notices must be delivered, and to whom
Default and cure: whether a monetary default requires written notice and a cure period before remedies apply
Late charges and default interest: the rate, the trigger, and any cap
Attorney fee clause: whether the prevailing party recovers fees
Security deposit or letter of credit: when and how it may be applied to arrears
Guaranties: if an individual guaranteed the lease, tell me at intake. I classify any guaranty issue before engagement

⚠️ Check Local Rules: Some cities impose added notice or protection rules for certain commercial tenants. Verify local requirements before serving a notice or filing an unlawful detainer.

Default Strategy: Attorney Demand vs. Formal Notice

When an Attorney Demand Comes First

Advantages:

Keeps a performing location: A business tenant with a short cash-flow gap may be worth keeping on a written plan
Demands the full lease balance: The letter can itemize rent, late charges, default interest, and other lease charges with the lease sections cited
Flexibility: Leaves room for a forbearance agreement without starting the eviction clock
Record for later: Documents the default and the tenant's response before any filing

Best For:

A first default by a tenant with a good payment history
A tenant that has communicated and proposed a realistic plan
Disputed charges (CAM reconciliations, pass-throughs) that need to be itemized
Situations where the location is valuable and re-letting would be slow

When to Serve the 3-Day Notice Promptly

Serve the statutory notice without delay when:

The tenant has a pattern of repeated defaults
The tenant has ignored prior written demands
The business appears to be winding down or moving assets out
The tenant has breached other lease covenants as well
A prior forbearance or payment plan was not honored

Late Charges and Default Interest

Commercial leases usually set late charges and default interest. Before demanding them:

Confirm the clause: the trigger date, any grace period, and whether written notice is required first
Calculate precisely: itemize each month and each charge; errors undermine the demand
Keep the statutory notice separate: the 3-Day Notice amount must follow CCP § 1161 and CCP § 1161.1, while the attorney letter can demand the full lease balance

Forbearance and Payment Plans

Benefits:

Avoids vacancy, re-letting cost, and litigation expense
Keeps rent flowing while the tenant recovers
Can add an acknowledgment of the balance and a clean default trigger

Risks:

The tenant may default again, delaying recovery of possession
Informal accommodations can be argued as a waiver or modification of the lease
A plan without a written default clause is hard to enforce

Best Practice: Put any plan in a written forbearance agreement: acknowledgment of the balance, a payment schedule, current rent paid on time, a default clause, and a reservation of the landlord's rights under the lease.

Partial Payments

⚠️ Handle Partial Payments in Writing: The rules on partial payments after a notice differ for commercial property (see CCP § 1161.1) and depend on the lease. Decide how the notice and any partial payment fit together, in writing, before you accept money.

How to Write an Effective Commercial Rent Demand

Two Approaches: Measured vs. Firm

Measured Approach: For a first default by a valued tenant. States the balance and the lease sections, invites a written proposal, and sets a deadline.

Firm Approach: For repeat defaults or ignored demands. States the exact balance, the deadline, and the next steps under the lease and CCP § 1161.

Essential Components

Component	What to Include
Parties	The landlord entity and the tenant's exact legal name as it appears on the lease

Next Steps	The remedies the lease and the statute allow if the balance is not paid

Delivery Method

Follow the lease notice clause: address, method, and any copy-to party

What NOT to Include

Guesses: never estimate charges you cannot document
Residential rules: do not cite residential tenancy statutes in a commercial demand

Commercial Unlawful Detainer: From 3-Day Notice to Judgment

Step 1: Serve the 3-Day Notice to Pay Rent or Quit

If the attorney demand does not resolve the default, serve the statutory notice:

Content: The amount due as CCP § 1161 and CCP § 1161.1 allow, the period, and the demand to pay or surrender possession
Service Methods: Personal service, substituted service, or posting and mailing under CCP § 1162, plus anything the lease requires
3-Day Calculation: Excludes Saturdays, Sundays, and court holidays

⚠️ Common Errors That Undermine a Notice: • An amount that does not match the lease and the statute • The wrong tenant entity or premises description • Improper service under CCP § 1162 • Not giving the tenant the option to pay

Step 2: Wait for the Notice Period to Expire

An unlawful detainer cannot be filed until the notice period has run
If the tenant pays the amount due within the period, the default is cured on that notice
Handle any partial payment in writing before accepting it (see the Default Strategy tab)

Step 3: Unlawful Detainer Complaint

If the tenant neither pays nor surrenders possession, an unlawful detainer can be filed in superior court:

Forms: Complaint (UD-100), Summons (SUM-130), Civil Case Cover Sheet (CM-010)
Filing Fee: Approximately $240-$435 depending on county and amount
Entity Plaintiff: A landlord that is a company or LLC must appear through a licensed attorney

Step 4: Tenant's Response

The summons states the short period the tenant has to respond:

Common business-tenant responses: disputes over the amount, claimed landlord breach (repairs, access, CAM reconciliation), claimed offsets, or a defective notice
If the tenant does not respond: the landlord may request a default judgment
If the tenant responds: the case proceeds toward trial

Step 5: Trial and Judgment

The landlord must prove the default and a proper notice
If the landlord prevails, the court enters judgment for possession and the amounts proven

Step 6: Writ of Possession

The landlord requests a Writ of Possession from the court
The levying officer posts a notice to vacate and later returns possession to the landlord

Approximate Timeline

Step	Timeframe
3-Day Notice	3 days (excluding weekends and court holidays)
File and serve the complaint	About 1 week
Response period and trial setting	Varies by county
Total: Uncontested Case	Roughly 30-45 days
Total: Contested Case	Roughly 60-90 days or longer

Business Tenant in Bankruptcy: A bankruptcy filing by the tenant triggers the automatic stay. Stop collection and eviction steps and get advice before taking further action.

Attorney Services for Commercial Landlords

Business Tenant Behind on Rent?

I work with commercial landlords on business-tenant rent defaults: an attorney demand on my letterhead citing the lease, review of the lease default notice and the 3-Day Notice before service, and a draft unlawful detainer complaint where warranted. Filing and representation are separately scoped engagements confirmed in writing.

How I Can Help

Commercial Rent Demand Letters: An itemized demand to the business tenant, citing the lease sections and deadlines
Notice Review: A check of the lease default notice and the 3-Day Notice against the lease and CCP §§ 1161, 1161.1 and 1162 before service
Default Analysis: Cure periods, late charges, default interest, attorney fees, and application of the deposit or letter of credit
Draft Complaint: A draft unlawful detainer complaint where it adds leverage, marked DRAFT - NOT FILED
Forbearance or Surrender Agreements: A written payment plan or an early surrender and termination agreement, as a separately scoped negotiation phase

What I Do Not Take

Landlord-side collection of residential rent from individual tenants
Residential evictions for landlords
Collection of consumer debts or personal, family or household loans

Tenants who received a rent demand or a notice can use my tenant-side response guides.

When to Involve an Attorney

Consider attorney help if:

The business tenant has ignored written demands
The lease has notice, cure, or guaranty provisions you need applied correctly
The tenant disputes charges or claims offsets
The balance or the value of the location justifies an attorney letter
The landlord is an entity that will need counsel for any filing
The tenant has filed bankruptcy (automatic stay)

Frequently Asked Questions

Yes, if the lease provides for them and they are calculated correctly. The attorney demand can itemize the full lease balance. The amount stated in the 3-Day Notice is a separate question: it must follow CCP § 1161 and, for commercial real property, CCP § 1161.1, so I keep the statutory notice and the demand letter consistent with each other and with the lease.

The rules on partial payments differ for commercial property (see CCP § 1161.1) and also depend on the lease. Before accepting a partial payment, decide in writing how it affects the notice and reserve your rights under the lease.

Uncontested matters often take roughly 30 to 45 days from the notice to recovery of possession. Contested matters take longer, commonly 60 to 90 days or more. Timing varies by county and by how the tenant responds.

Do not act on self-help without reviewing the lease and current California law with counsel. The unlawful detainer process is the safe route to possession, and a wrongful lockout can create liability for the landlord.

Business tenants often raise repair, access, or CAM reconciliation disputes and claim offsets. Whether the lease allows offsets or conditions rent on landlord performance usually decides how much weight those arguments carry. Document your performance and answer the claims in writing.

Sometimes. A written forbearance agreement with an acknowledgment of the balance, a payment schedule, a default clause, and a reservation of rights can keep a valuable location paying. If an individual guaranteed the lease, tell me at intake: I classify any guaranty issue before engagement.
