In California, a landlord ending a periodic commercial tenancy must give a written 60-day notice to vacate when the tenant has occupied the property for a year or more. The rule comes from Civil Code Section 1946.1, and it applies whether the space is an office, a storefront, a warehouse, or any other nonresidential property held on a month-to-month basis. The lease itself can require a longer notice or add procedural steps, and courts hold landlords to whatever the lease says. Notice defects — wrong content, wrong delivery, wrong timing — routinely cost landlords months of delay and legal fees that outrun the original dispute.
When the 60-Day Rule Applies
Civil Code Section 1946.1 sets the floor. A landlord terminating a periodic tenancy owes at least 60 days’ written notice if the tenant has been in the property for one year or more. If the tenant has been there less than a year, 30 days is enough.1California Legislative Information. California Civil Code 1946.1 Section 1946.1 overrides the older, shorter default in Section 1946.
A tenant’s obligation runs the other way. Under Section 1946.1, a tenant must give notice equal to the length of the periodic term, so a month-to-month tenant gives 30 days regardless of how long the business has been in the space.1California Legislative Information. California Civil Code 1946.1
The 60-day rule applies to periodic tenancies — arrangements with no fixed end date. A fixed-term commercial lease expires on the date written in the lease, and no 60-day notice is needed to end it unless the lease says otherwise. The 60-day notice matters most when a fixed-term lease has expired and the tenant has stayed on, creating a month-to-month holdover.
What the Notice Must Include
California law requires the notice in writing but does not impose a rigid format for commercial terminations. A notice holds up better against a challenge when it contains:
- The full property address, including any unit or suite number.
- The names of the landlord (or property manager) and every tenant on the lease.
- The date the notice is served, which starts the 60-day clock.
- The specific date the tenant must vacate, at least 60 days out.
- Contact information for questions.
Commercial notices generally do not need to state a reason for termination unless the lease requires one. If the termination is based on a lease violation, documenting the specific breach in the notice strengthens the landlord’s position later.
How to Deliver the Notice
Read the lease first. Many commercial leases specify exactly how notices must be delivered, and a court will enforce those terms. A lease that requires certified mail to a designated address is not satisfied by handing the notice to a manager at the property.
When the lease is silent, the safest method is personal delivery to the tenant, or for a business entity to an officer, managing agent, or other person authorized to receive documents. A certified mail copy on top of personal delivery creates a paper trail if the tenant later claims the notice never arrived.
One common landlord mistake is citing Code of Civil Procedure Section 1162 as the rule for serving the 60-day notice. Section 1162 governs service of the shorter notices tied to unlawful detainer actions under Sections 1161 and 1161a, not the initial termination notice that ends the tenancy.2California Legislative Information. California Code of Civil Procedure 1162 Section 1162 becomes relevant later if a lawsuit is needed; it is not the authority for serving the 60-day notice itself.
How the Lease Can Change the Rules
Commercial leases routinely override statutory defaults, and California courts enforce those terms as long as they do not violate public policy. Common modifications:
- A longer notice period — 90 or 120 days is common — replaces the 60-day statutory floor.
- Termination-only-for-cause clauses prohibit no-cause terminations. A landlord who serves a no-cause 60-day notice under a cause-only lease has served an invalid notice.
- Specific service methods, such as certified mail, overnight courier, or delivery to a designated address, must be followed exactly. A notice that reaches the tenant by the wrong method can still be defective.
- Mandatory mediation or arbitration provisions can block a lawsuit filed before those steps are completed.
When lease language on termination is ambiguous, California courts generally interpret it against the drafter, which in commercial deals is usually the landlord. Form leases and templates deserve a legal review before they are relied on to end a tenancy.
Holdover Tenants After a Fixed-Term Lease
When a fixed-term commercial lease expires and the tenant keeps paying rent that the landlord keeps accepting, California treats the arrangement as a renewed periodic tenancy on the original lease terms. Civil Code Section 1945 creates this automatic renewal.3California Legislative Information. California Civil Code 1946
Once a holdover tenancy exists, the landlord cannot self-help by changing locks or blocking access. The formal notice process applies, and a tenant of a year or more still gets 60 days. Accepting a single rent payment after lease expiration can be enough to establish the holdover, so a landlord planning not to renew should serve the 60-day notice before expiration or stop accepting rent afterward.
What Tenants Should Do After Receiving a Notice
Pull the lease out and compare it against the notice. Check the notice period, the property description, and the delivery method against what the lease requires. A defect can make the notice unenforceable, though pointing one out usually just prompts a corrected notice rather than saving the tenancy for good.
If the notice is valid, the tenant’s obligations are to vacate by the termination date and return the space in the condition the lease requires. Most commercial leases include a restoration clause covering fixtures, signage, and tenant improvements. A “broom clean” requirement means free of trash, debris, and the tenant’s belongings; it does not mean professionally cleaned or repainted unless the lease says so.
Tenants who need more time should negotiate early. Landlords sometimes agree to a short extension or a temporary month-to-month while the tenant relocates, but there is no legal right to additional time once a valid 60-day notice has been served. Rent remains due through the termination date. A tenant who stops paying gives the landlord grounds for a separate three-day notice to pay or quit, which accelerates the timeline sharply.
Security Deposit Return
Civil Code Section 1950.7 governs commercial security deposits. After the landlord regains possession, the landlord may deduct only amounts reasonably necessary for unpaid rent, tenant-caused damage, or cleaning.4California Legislative Information. California Civil Code 1950.7
The balance must be returned no later than 30 days after the landlord receives possession. If the deposit exceeds one month’s rent plus any last-month’s-rent deposit and the only claim is unpaid rent, the excess above one month’s rent must be returned within two weeks, with the remainder following inside the 30-day window.4California Legislative Information. California Civil Code 1950.7 Section 1950.7 does not require an itemized statement of deductions, though providing one heads off disputes.
If the Tenant Refuses to Leave
A tenant who stays past the 60-day termination date is in unlawful detainer. Under Code of Civil Procedure Section 1161, remaining in possession after the tenancy has been properly terminated is the trigger for California’s fast-track eviction proceeding.5California Legislative Information. California Code of Civil Procedure 1161 The landlord files a complaint in the superior court for the county where the property sits, and a served tenant has 10 days to respond, with an additional five court days if service was by mail.6California Legislative Information. California Code of Civil Procedure 1167 Missing that deadline usually produces a default judgment.
At the unlawful detainer stage, Code of Civil Procedure Section 1162 controls service of the required notices on a commercial tenant. The statute lays out three methods that must be attempted in order:2California Legislative Information. California Code of Civil Procedure 1162
- Personal delivery to the tenant, or to a person authorized to accept legal documents for a business entity.
- Substitute service, meaning leaving the notice with a responsible person at the property and mailing a copy to the tenant at the property address.
- Post and mail, meaning affixing the notice in a conspicuous spot after reasonable effort to find someone at the premises, and mailing a copy.
Document every step: dates, times, names of anyone who accepted the notice, and photos of posted notices. Tenants defending an eviction will comb the service record for defects, and courts will dismiss cases over them.
Attorney Fees
Most commercial leases include an attorney fee clause, and Civil Code Section 1717 makes those clauses reciprocal. Even if the lease says only the landlord can recover fees, the prevailing party in a lease dispute — whichever side wins — is entitled to reasonable fees from the loser.7California Legislative Information. California Civil Code 1717 A landlord who pushes a weak eviction and loses can owe the tenant’s legal bills. A tenant who mounts a frivolous defense faces the same exposure. This is a strong push toward early negotiation on both sides.
If the Tenant Files Bankruptcy
A commercial tenant facing eviction can file bankruptcy, which triggers the federal automatic stay and freezes collection and eviction actions the moment the petition is filed.8Office of the Law Revision Counsel. 11 USC 362 – Automatic Stay
There is one narrow exception for commercial landlords. Under 11 U.S.C. § 362(b)(10), the stay does not apply if the lease of nonresidential real property expired by its stated term before the bankruptcy filing or expires during the case.8Office of the Law Revision Counsel. 11 USC 362 – Automatic Stay Courts read “stated term” strictly to mean the calendar end date written in the lease, not an early termination triggered by tenant default. A landlord who terminated for nonpayment rather than waiting for the term to expire probably cannot use the exception, and the stay blocks further eviction until the bankruptcy court lifts it or the case resolves. Any procedural misstep during the stay can produce sanctions, and a bankruptcy attorney should be involved from the moment a tenant files.
