What is an option to renew in a commercial lease, and what if I miss the deadline to exercise it?
The short answer
An option to renew gives the tenant the right to extend the lease for an additional term, typically by providing written notice within a specified window before the expiration date. Missing that window — which commonly runs from 6 to 12 months before the lease ends — typically forfeits the renewal right entirely, leaving the tenant to negotiate a new lease from scratch or face holdover rent. Even when the option is exercised on time, the renewal rent structure matters: many renewal options set rent at 'fair market value' determined at the time of exercise, which may be substantially higher than the expiring rent and may not include the TI allowance or incentives that came with the original lease. Scan your lease to find the renewal option's notice deadline and understand how renewal rent is set before the window approaches.

What an option to renew usually does
A renewal option gives the tenant the right — but not the obligation — to extend the lease for a defined additional term (commonly three or five years) by delivering written notice to the landlord within the option's notice window. The window is typically stated as a number of months before the expiration date: notice by the deadline exercises the option; notice after the deadline is typically treated as no notice at all. Some leases allow the landlord to provide a reminder notice, but many do not — the obligation to track the deadline belongs to the tenant.
The renewal rent mechanism is the second critical term: a common structure sets renewal rent at 'fair market value' to be agreed upon or determined by appraisal if the parties cannot agree. 'Fair market value' at the time of renewal may reflect market conditions significantly different from those at the original signing — potentially higher rent, without the tenant improvement allowance or free-rent periods that accompanied the initial lease. Tenants who exercise a renewal option give up their leverage to negotiate a new deal with incentives.
Why people worry about the renewal rent and fair market rate exposure
Tenant advisors commonly describe two compounding risks at renewal: missing the notice deadline (forfeiting the option) and finding that 'fair market rent' at the time of renewal is substantially above the expiring rent. A tenant who relied on the option to stay in their space at a known cost may face either a forced relocation if the option is forfeited or an unexpected rent increase if the option is exercised but the renewal rent is reset to current market levels. Negotiating a stated renewal rent or a capped formula — rather than an open-ended fair market value determination — at the time of the original lease signing is the most tenant-protective approach.
What to look for in your lease
- The renewal option's notice deadline — how many months before expiration notice must be given, and in what form.
- Whether the option is automatically forfeited if not timely exercised, or whether a cure window exists.
- How renewal rent is set — fixed step, stated percentage increase, or fair market value — and the process for determining fair market value if disputed.
- Whether the option survives any default in the original term, or is forfeited upon a prior default.
- Whether renewal periods stack — can you exercise a second renewal after completing the first renewal term?
Questions to ask before signing
- Ask the landlord to confirm the renewal option notice deadline and calendar it at signing.
- Ask the other party to clarify how renewal rent is set and whether a stated escalation formula is available instead of fair market value.
- Confirm whether the option is forfeited upon any prior default and what 'default' means in this context.
- Consider having the lease reviewed to assess the renewal option mechanics before relying on it as part of your business plan.
Why scan instead of guess

Common questions
What happens if I miss my renewal option deadline?
Typically, the renewal right is forfeited. The tenant loses the right to extend on the option terms and must either negotiate a new lease from scratch — which may involve a higher rent, different terms, and no guarantee of staying in the space — or vacate at the end of the original term. Courts have occasionally granted relief for missed option deadlines in limited circumstances, but relying on that outcome is not a recommended substitute for calendaring the deadline.
What is 'fair market rent' in a renewal option?
The rent that a landlord and a comparable tenant would agree to in an arm's-length transaction for the same space at the time of renewal. When the parties cannot agree, many leases provide for appraisal or arbitration. The result may be higher or lower than the expiring rent, depending on market conditions at renewal. A stated renewal rent formula eliminates this uncertainty.
Can I negotiate a fixed renewal rent at the time of the original lease signing?
Often yes — a stated annual escalation applied to the expiring rent, a fixed dollar amount, or a capped fair market value are all structures that tenant advisors commonly seek in lieu of an open-ended fair market determination. Whether a landlord will agree depends on the market and the tenant's leverage at the time of the original negotiation.
