We Missed the Deadline to Renew Our Commercial Lease: Is the Option Gone?

Last updated: November 2026. Reviewed by Pavel Kolmogorov, California business litigation attorney (State Bar No. 321018).

Usually the option is lost, unless the landlord helped cause the delay or gave up the deadline. A renewal option in a California commercial lease must be exercised in the time and manner the lease states, and courts have refused to rescue a tenant whose lateness was its own oversight. Relief is possible for fraud, accident, or mistake, or where the landlord's conduct led the tenant to miss the date. One rule helps: absent contrary lease language, a notice is effective when mailed. Kolmogorov Law, P.C. handles these disputes.

What to do the day you find the mistake

The calendar entry was wrong, or the employee who tracked the lease left the company, and the notice date passed. Do four things before calling the landlord to apologize.

• Reread the option clause. Note the deadline, how notice must be given, to whom, and any conditions, such as being free of default.
• Send a written exercise immediately, in the manner the clause requires. A late notice costs nothing, and a landlord that accepts it may be found to have waived the date.
• Gather every communication with the landlord or its manager about renewal, from before and after the deadline.
• Keep paying rent and performing the lease.

What the landlord said and did will matter more than the tenant's reasons.

Why courts enforce the date strictly

A renewal option is an offer the landlord must keep open. If the tenant does not accept it within the time allowed, it expires by its own terms. That is why a late exercise is treated differently from a late rent payment.

In one Court of Appeal case, a commercial tenant gave notice three months after the lease's deadline. It argued that substantial improvements it had made to the premises showed its intent to stay. The court affirmed judgment for the landlord. A tenant must exercise a renewal option in the time, in the manner, and on the terms stated in the lease. A tenant's conduct alone does not justify relief. There can be no substantial compliance with an option that was never accepted. (Bekins Moving & Storage Co. v. Prudential Ins. Co. (1985) 176 Cal.App.3d 245.)

Our page on options and rights of first refusal discusses another decision that reached the same result on a shorter delay.

The forfeiture statute usually does not help

California allows a court to relieve a party from a forfeiture on full compensation to the other side, except where the breach was grossly negligent, willful, or fraudulent. (Civ. Code, § 3275.) A tenant who has invested in its space will want to invoke it. The same decision rejected that argument. A forfeiture requires a right or vested interest, the court said, and an unexercised option is only an offer. (Bekins, supra, 176 Cal.App.3d 245.)

Three grounds that can save a late exercise

The notice was on time after all. The California Supreme Court has held that, absent contrary language in the option, the exercise is effective when written notice of acceptance is deposited in the mail. The lease in that case required written notice and said nothing about how it had to be sent, so ordinary mail was enough. (Palo Alto Town & Country Village, Inc. v. BBTC Co. (1974) 11 Cal.3d 494.) The statute behind the rule treats consent as communicated once the accepting party puts its acceptance in the course of transmission. (Civ. Code, § 1583.) A notice clause that makes notices effective on receipt changes the answer.

The landlord caused or accepted the delay. Courts have tied relief to conduct by the landlord on which the tenant relied in failing to give notice. A manager who said the paperwork could wait, renewal terms negotiated past the deadline, or a landlord that treated a late notice as good may each support waiver or estoppel. Our page on waiver and estoppel explains those doctrines.

Fraud, accident, or mistake. Courts keep the traditional grounds for equitable relief open. Ordinary oversight is not one of them.

If the option is gone

The lease continues to its stated end. After that, a tenant who stays is a holdover, and its rights depend on whether the landlord accepts rent. Our page on commercial holdover tenants covers that position.

A tenant still has things to offer in a negotiation for a new lease: an occupied space, a payment history, and the landlord's cost of finding a replacement. What it no longer has is the option's rent formula.

If you are the landlord

A lapsed option can be revived by loose handling. Answer a late notice promptly and in writing, and say that the option expired. Do not describe later discussions as a renewal under the option. Check when and how the tenant's notice was sent before relying on the date it arrived.

If the clause sets conditions, such as no uncured default, establish the facts as of the exercise date. Our page on conditions precedent explains how courts treat them.

What to bring to the first meeting

• The lease and every amendment, with the option clause and the notice clause marked.
• The exercise notice, proof of when and how it was sent, and proof of receipt.
• Emails, letters, and texts with the landlord or property manager about renewal.
• Records of improvements made and rent paid.
• Any response from the landlord, including a proposed new lease.

Frequently asked questions

We missed the deadline to exercise our lease renewal option by two weeks. Have we lost the space?

Possibly, but check three things before conceding. California courts hold a commercial tenant to the time and manner the option clause states, and neglect alone does not earn relief. The option may survive if your notice was mailed in time, if the landlord's words or conduct led you to miss the date, or if the landlord waived it afterward. Send a written exercise now and collect every communication with the landlord.

Can a court excuse a late lease renewal notice in California?

Only on narrow grounds. The California Court of Appeal has said a court may grant relief for fraud, accident, or mistake. It may not extend an option period when the delay was due entirely to the tenant's own inadvertence and the landlord did nothing to cause it. (Bekins Moving & Storage Co. v. Prudential Ins. Co. (1985) 176 Cal.App.3d 245.) In that case a tenant three months late lost its renewal.

Our renewal notice was mailed on the last day but the landlord received it three days later. Was it on time?

It may have been. The California Supreme Court has held that, unless the option says otherwise, the exercise of an option is effective when written notice of acceptance is deposited in the mail. (Palo Alto Town & Country Village, Inc. v. BBTC Co. (1974) 11 Cal.3d 494.) Read the notice clause of your lease first. If it makes notices effective on receipt, or requires a specific delivery method, that language controls.

Does spending money on tenant improvements show intent to renew?

Not by itself. In a California case the tenant argued that substantial improvements made shortly before the option date told the landlord it meant to stay. The Court of Appeal disagreed. A tenant's own conduct is not enough, and relief requires evidence of conduct by the landlord on which the tenant relied in failing to give notice. Written notice in the manner the lease requires is what counts.

What happens to a commercial tenant after a renewal option lapses?

The lease runs to its stated end. If the tenant stays afterward and the landlord accepts rent, California presumes a renewal on the same terms, month to month where rent is paid monthly. Either side can ordinarily end that tenancy on at least 30 days' written notice. (Civ. Code, §§ 1945, 1946.) Without the landlord's consent, the tenant is a holdover subject to unlawful detainer.
