A commercial lease renewal is where an incumbent tenant has the most to lose and, in a soft market, the most to gain. Your lease already sets most of the rules; here is how to use them.
The direct answerWhat Is a Commercial Lease Renewal?
A commercial lease renewal keeps a tenant in place for a new term after the current lease expires. Usually the tenant either exercises the renewal option in its lease, in the time and manner the lease requires, or negotiates a renewal amendment with the landlord. Miss the option window and that right ordinarily lapses.
A lease grants the right to possess and use property for a specified period of time in exchange for consideration, typically rent. Whether you extend by option notice, amendment or new lease decides which old clauses carry forward; have your attorney confirm which.
Key Takeaways
- A renewal option is a right, not an obligation, and it ordinarily ends if not exercised on time and as the lease requires.
- Inland Empire industrial availability sits at 12.5%, a 15-year high (Apex’s analysis of CoStar data, Q3 2026), but that tenant edge may narrow.
- Negotiate the whole package: free rent, allowance, term, a fresh option and CAM caps.
- A commercial lease holdover in California can end in unlawful detainer if you stay without permission.
What Is a Lease Renewal Option, and How Does the Deadline Work?
A lease renewal option is your right, not your obligation, to extend on the terms the clause spells out. The deadline is the exercise-notice window your lease sets, and it is rarely forgiving.
Per Cornell’s Legal Information Institute, the holder must generally exercise an option in accordance with its stated time, manner and other conditions. Read your commercial lease renewal option clause for the exercise dates, the required form of notice, any conditions, and how rent is set. Then calendar the dates.
An option is not a right of first refusal. An option may generally be exercised on its agreed terms without waiting for the owner, while a right of first refusal is typically triggered by the owner’s decision to sell or by a third-party offer.
| Path at expiration | Rent certainty | Your leverage | Main risk |
|---|---|---|---|
| Exercise the option | High if fixed; lower if it resets to market | Limited; the clause sets terms | Locking in above-market rent |
| Negotiate an amendment | Whatever you negotiate | Strongest with a credible alternative | Talks outlasting the deadline |
| Relocate | Set by the new lease | High where availability is elevated | Moving, downtime, build-out cost |
| Hold over | Low; your holdover clause governs | Weak; the landlord sets the timeline | Unlawful detainer if you stay without permission |
How Is Renewal Rent Set?
Your option clause sets renewal rent, usually by a fixed increase, a reset to fair market value (FMV), or an FMV reset with a floor at current rent. With FMV, check who sets it, which comparables count, and whether disputes go to appraisal or arbitration.
Hypothetical worked example · illustrative numbers, not a market quote
A tenant leases 10,000 SF at $2.00/SF per month: $20,000 a month.
- Fixed 3% increase: $2.06/SF, or $20,600 a month.
- FMV appraised at $1.80/SF: $18,000 a month, saving $24,000 a year versus today. With a floor, it stays $20,000.
- FMV appraised at $2.30/SF: $23,000 a month, $28,800 a year more than the fixed increase.
The same clause can save or cost five figures a year, depending on the market when you exercise.
Check the structure too, using our guide to the types of commercial leases: are you on a triple net (NNN) lease or a modified gross lease with a base year, and would a reset base year raise your expense share?
Local leverageWho Has the Leverage in an Inland Empire Lease Renewal Right Now?
For now, mostly the tenant: CoStar’s Q3 2026 Inland Empire industrial report says leverage remains with occupiers.
Apex’s analysis of CoStar data · Inland Empire Industrial Market Report · Q3 2026
- Vacancy 8.7%; availability 12.5%, a 15-year high.
- Triple-net asking average for available space about 25% below its 2023 peak, after an apparent bottom in 2025 Q1.
- With concessions, effective rents up to 40% lower, per brokers cited by CoStar, depending on location, size and vintage.
- Sublease space is 19% of availability, trading more than 20% below direct space.
That relocation alternative is what gives a lease renewal negotiation its teeth. CoStar adds that one to several months of free rent is common for new, larger leases of five years or longer: a new-lease benchmark, but what a competing landlord may offer. Check what warehouse space costs in the Inland Empire and the Inland Empire industrial market before you open talks.
Why incumbents still get surprised: CoStar notes longer-term Inland Empire industrial tenants still face rent hikes at lease expiration; market asking rents are still up approximately 20% from five years ago and have nearly doubled over the past decade.
Retail tenants have a milder edge: CoStar puts Inland Empire retail vacancy at 6.0% in Q3 2026 and says landlords’ ability to push market pricing higher is limited, though market rents are up 18% over the past five years, creating meaningful rent spreads for long-term tenants nearing expiration. See the Inland Empire retail market report.
The window may be closing. CoStar forecasts industrial rents to rise again in 2027 as stronger demand and slower completions drive vacancy lower, and its forecast has vacancy falling to 8% in 2027 and near 7% by the end of 2028.
TimingWhen Should You Start Negotiating a Commercial Lease Renewal?
Start before your option notice window opens, early enough that relocating is a real option rather than a bluff.
Local evidence · Apex’s analysis of CoStar data, Inland Empire Industrial, Q3 2026
Tenants are active: new leasing volume totaled around 50 million SF in 2025, for just the second time ever, and Q2 2026 set a quarterly record of over 13 million SF. CoStar adds that the minimal development on track to deliver in the coming year signals potential strengthening of fundamentals.
Good space is still contested: CoStar reports Inland Empire industrial buildings smaller than 50,000 SF remain in stronger demand, with availability under 7%. Our advice: benchmark the market before the window opens, and if a move is possible, review how the commercial leasing process works.
The playbookHow Do You Negotiate a Commercial Lease Renewal?
Negotiate from a documented alternative, on a calendar you control, and put every term in writing. Here is how to negotiate commercial lease renewal terms.
- Pull the lease and every amendment. Find the option, notice window, holdover clause and conditions.
- Calendar the deadline twice. Yours and your attorney’s.
- Benchmark effective rent, not just asking. In the Inland Empire, the triple-net asking average for available space is about 25% below its 2023 peak, and with concessions, brokers cited by CoStar put effective rents up to 40% lower.
- Build a real relocation alternative. Tour, price and shortlist, including discounted sublease space.
- Open talks before the option window. A landlord who knows you have time negotiates differently.
- Paper it in a signed amendment. An email thread is not a renewal.
- If talks stall and the option terms work, exercise it in writing, in the time and manner the lease requires.
An advisor pulls comparables, runs the relocation math and handles the lease renewal negotiation. That is the work behind Apex’s tenant-side representation.
Beyond base rentWhat Should You Ask For Besides Rent?
Ask for everything that changes your total occupancy cost and flexibility; base rent is one line. CoStar reports Inland Empire industrial landlords often offer several months of free rent, even on some shorter-term deals; a competing landlord’s offer is your benchmark. For sizing that allowance itself, see our guide to tenant improvement allowance.
| Renewal ask | Why it matters |
|---|---|
| Free rent | Lowers effective cost across the term |
| Improvement allowance | Funds a refresh without new capital from you |
| Term and a fresh option | Trades commitment for concessions and protects the next renewal |
| CAM caps and audit rights | Limits how fast shared costs climb and lets you verify them |
| Assignment, sublease and early exit | A way out, or a way to shrink, if the business changes |
| Lease structure | Shifts who pays operating costs |
Before trading rent for expenses, read our guides to CAM charges and caps and gross vs. net lease structures. For the year-end audit itself, see our guide to CAM reconciliation.
Commercial lease holdoverWhat Happens If You Miss Your Renewal Option Deadline?
Usually the option is gone: an option not exercised before it expires ordinarily ends. Stay past expiration anyway and you are in a commercial lease holdover, governed by California’s default rules and your lease’s holdover clause.
LII warns that parties may unintentionally bind themselves to a new lease without ever signing one. In LII’s general definition, a wrongful holdover creates a tenancy at sufferance, and the landlord can collect rent for the holdover period.
California default rules · statutory text checked September 23, 2026
- Civil Code § 1945: if you stay after expiration and the landlord accepts rent, the parties are presumed to have renewed on the same terms, not exceeding one month when rent is payable monthly, nor in any case one year.
- Civil Code § 1943: a non-residential hiring is presumed month to month unless otherwise designated in writing, where no custom or usage applies.
- Civil Code § 1946: either party may end a month-to-month tenancy with at least 30 days’ written notice.
- Code of Civil Procedure § 1161: a tenant who stays after the term expires, without the landlord’s permission, is guilty of unlawful detainer.
- Code of Civil Procedure § 1174: in an unlawful detainer case where malice is shown, statutory damages of up to $600 may be awarded on top of actual damages, including rent found due.
These are defaults and presumptions. Many leases set a higher holdover rent, so read your clause and Civil Code § 1945 at the source.
A note on legal advice: renewal options, holdover and lease clauses turn on your lease’s exact wording. Apex Real Estate Services is not a law, tax or accounting firm. Have your attorney review the lease and any notice, and your CPA the numbers, before you sign or let a deadline pass.
Commercial Lease Renewal: Frequently Asked Questions
Short answers to the renewal questions tenants ask most.
How far in advance should I negotiate a commercial lease renewal?
Before your option notice window opens, early enough that relocating is a real alternative. Inland Empire industrial leasing hit a quarterly record of over 13 million SF in Q2 2026, per CoStar, so leave time to tour, price and shortlist other space.
What happens if I miss the deadline to exercise my lease renewal option?
The option ordinarily ends. You can still negotiate, just without the right. If you stay past expiration, California presumes a renewal on the same terms, capped at one month when rent is payable monthly, if the landlord accepts rent; staying without permission can be unlawful detainer.
Can my landlord raise the rent when I renew a commercial lease?
Yes, if your option clause provides a fixed increase or a fair market value reset; without an option, rent is negotiated. CoStar notes Inland Empire industrial market asking rents are still up about 20% from five years ago.
Is a lease renewal option the same as a right of first refusal?
No. An option can generally be exercised on its agreed terms without waiting for the owner. A right of first refusal is typically triggered by the owner’s decision to sell or by a third-party offer. Check which one your lease grants.
What is a holdover tenant in a commercial lease?
A tenant who stays after the lease ends without signing a new lease. In California, if the landlord accepts rent, the parties are presumed to have renewed on the same terms, for no more than one month when rent is payable monthly. Many leases set a different holdover rent, so check your holdover clause.
Should I use a tenant rep broker to renew my lease?
Usually, yes. A tenant rep benchmarks effective rent, builds a relocation alternative and runs the negotiation, so the deadline doesn’t run you.
