Evicting a commercial tenant in California is not the same process as a residential eviction, and treating it that way is one of the fastest ways for a landlord to lose time, money, and leverage. Commercial tenants have fewer statutory protections than residential tenants, but the unlawful detainer process itself is still governed by strict procedural rules, and a single mistake in a notice or a filing can send you back to square one.
This guide walks through the process step by step: establishing grounds, serving notice, filing suit, getting through court, and enforcing a judgment. For a broader look at the risks landlords face around lockouts and liability, see our companion article on commercial evictions and lockouts.
Step 1: Establishing Valid Grounds for Eviction
Before anything gets served or filed, you need a legally sufficient reason to terminate the tenancy. The most common grounds in commercial eviction proceedings are:
- Nonpayment of rent: This is the most frequent basis for commercial eviction that we see in our practice, and the one with the clearest statutory notice requirement.
- Lease violations: Unauthorized alterations, prohibited uses, unauthorized subletting or assignment, or violations of use restrictions written into the lease.
- Holding over: The tenant remains in possession after the lease term has expired, or after a month-to-month tenancy has been properly terminated.
- Nuisance or illegal use of the premises: Conduct that interferes with other tenants or the property itself, or use of the space for unlawful purposes.
Reviewing the lease should always be the starting point for eviction considerations. Commercial leases are negotiated documents, and many contain default and cure provisions that provide the tenant more protections than the statutory minimums. A landlord who skips straight to serving an eviction notice without checking whether the lease requires, say, a longer cure period or a specific method of notice, risks serving a notice that a court later finds noncompliant with the parties’ own agreement.
Step 2: Serving Proper Notice
This is where most commercial eviction cases succeed or fail before they ever reach a courtroom. California landlord-tenant law requires strict compliance with notice procedures, and penalizes landlords who don’t follow them. A defective notice is one of the most common reasons an unlawful detainer case gets dismissed or delayed.
Depending on your situation, you may need to serve any of the following types of notice to the tenant:
- Three-day notice to pay rent or quit: For nonpayment, the notice must state the exact amount of rent due, the name, phone number, and address of the person to whom payment should be made, and, if in-person payment is available, the days and hours someone will be available to accept it. The requirements trace back to California Code of Civil Procedure section 1161(2). Our commercial eviction attorneys can help you confirm whether this applies to the specific facts of your situation.
- Three-day notice to perform covenant or quit: This is used for curable lease violations, such as an unauthorized use of the premises. The tenant has three days from service to fix the violation and thereby preserve the lease.
- Notice to quit (no cure period): For violations the law treats as incurable, such as certain nuisance conduct, no opportunity to cure is required before proceeding.
- 30-day, 60-day, or 90-day notices: For month-to-month commercial tenancies or holdover situations, longer notice periods generally apply, and the specific length can depend on how long the tenant has occupied the space.
How you serve the notice to the tenant matters as much as what the notice says. Notices can typically be served personally, through substituted service on a person of suitable age at the premises followed by mailing, or, when those methods fail, by posting on the premises and mailing a copy. Getting the service method wrong, even when the notice’s content is otherwise correct, can be enough for a tenant’s attorney to challenge the entire proceeding.
Step 3: Filing the Unlawful Detainer Action
If the notice period expires and the tenant hasn’t paid, cured, or vacated, the next step is filing an unlawful detainer complaint in Superior Court. Every unlawful detainer action in San Diego County, commercial or residential, must be filed in the Central Division of the San Diego Superior Court at the Hall of Justice, located at 330 W. Broadway, Room 225, San Diego, CA 92101. Filing in the wrong branch will delay the case.
The filing requires several components:
- The complaint, which lays out the tenancy, the grounds for eviction, the notice served, and the relief requested.
- A summons, which must be properly issued and served on the tenant along with the complaint.
- Supporting attachments, including a copy of the lease and a copy of the notice with proof of service.
Unlawful detainer actions are designed to move faster than ordinary civil litigation, which is part of why the earlier steps need to be airtight. Once the notice period has run and the complaint is filed, the tenant has a short window, typically just a few court days, to respond. That compressed timeline cuts both ways: it benefits landlords with clean paperwork, and it punishes landlords who filed before dotting every procedural “i.”
Step 4: Court Proceedings
In San Diego, your tenant’s response deadlines depend on the service method. Personal service gives the tenant five days to respond, while substitute service or post-and-mail service extends that window to fifteen days. What happens next depends on how the tenant reacts.
- If the tenant does nothing: The landlord can request entry of default, and in many cases obtain a default judgment without a full trial.
- If the tenant responds and contests the case: Common commercial tenant defenses include disputes over the amount of rent owed, arguments that the notice itself was defective, claims that the landlord breached the lease first, or assertions that the landlord accepted rent after serving the notice (which can be treated as waiving the notice, depending on the circumstances).
- Trial: Unlawful detainer trials move on an expedited calendar compared to general civil matters. Because the underlying statute favors a quick resolution of possession disputes, courts generally set these matters for hearing well ahead of an ordinary civil trial date. San Diego courts generally set unlawful detainer trials ten to twenty days out, but this can vary depending on how crowded the court’s calendar happens to be.
Timeline expectations vary by court calendar and by whether the tenant contests the case, but landlords with clean notice and filing paperwork can often expect resolution measured in weeks rather than months. A contested case with motion practice will take longer.
Step 5: Enforcement: Writ of Possession and Sheriff Lockout
Winning in court doesn’t put a landlord back in possession on its own. Enforcement has its own steps.
After judgment, the sheriff posts the writ of possession along with a five-day notice to vacate, and the physical lockout follows five days after that posting. Landlords should plan around roughly a week between obtaining the writ and regaining physical possession.
While you’re waiting for that, it’s important to understand that you are not permitted to enforce the eviction personally. California law does not permit landlords to change locks, remove a tenant’s property, or shut off utilities to force a tenant out, even after winning a judgment. Only the sheriff, acting under a validly issued writ, can carry out the lockout. Landlords who attempt self-help eviction expose themselves to significant liability, a topic covered in more depth in another of our articles on commercial evictions and lockouts.
When to Involve a Commercial Eviction Attorney
Every stage above looks straightforward on paper. However, they all have procedural traps that can cost a landlord weeks or months of lost rent if handled incorrectly. Notice defects, improper service, missed cure periods, and premature filings are the most common ways commercial eviction cases go sideways, and courts in California hold landlords to strict compliance with the statute regardless of how clear-cut the underlying nonpayment or violation might be.

Frequently Asked Questions
How long does a commercial eviction take in California?
It depends heavily on whether the tenant contests the case. With a properly served notice and a clean unlawful detainer filing, an uncontested commercial eviction can move from notice to judgment in a matter of weeks. A contested case, especially one involving disputed defenses or motion practice, can extend the timeline to several months.
Can a commercial landlord in California change the locks without going to court?
No. California law does not allow landlords to lock out a commercial tenant, remove their property, or shut off utilities to force them out, even when the tenant is clearly in breach. Only the sheriff, acting on a writ of possession issued after judgment, can carry out a lockout. Landlords who attempt self-help eviction risk significant liability.
What is the difference between a three-day notice to pay rent or quit and a three-day notice to perform covenant or quit?
A notice to pay rent or quit applies specifically to nonpayment of rent and must state the exact amount owed along with payment details. A notice to perform covenant or quit applies to other curable lease violations, such as an unauthorized use of the premises, and gives the tenant three days to fix the violation rather than pay a sum certain.
Does a commercial tenant have the same eviction protections as a residential tenant in California?
No. Commercial tenants generally have fewer statutory protections than residential tenants, and many commercial leases contain their own default and cure provisions that supplement or modify the statutory minimums. That said, the unlawful detainer process itself still requires strict procedural compliance regardless of whether the tenant is commercial or residential.
What happens if a commercial landlord accepts rent after serving a notice to quit?
Accepting rent after serving a notice can, depending on the circumstances, be treated as waiving that notice, which would require the landlord to start the process over. Landlords who are mid-eviction should talk to their real estate litigation attorney before accepting any partial or late payment from the tenant.
