A lease renewal is a decision as much as a deadline. For a commercial property owner, the choice is between keeping a tenant on new terms and re-leasing the space, and each path has costs. This guide helps owners of office, retail and industrial property prepare for that decision: assess how the tenant has performed, compare renewal with the risk of vacancy, get ready for the conversation, and document what is agreed.
This guide is about commercial leases. Residential rentals follow different rules for rent increases and notices, and those rules do not apply here. For a commercial lease, the lease itself is the starting point.
Key Takeaways
- Start with the lease. Renewal options, notice requirements, rent formulas and holdover terms are set by the lease, not by a general rule.
- Judge the tenant on evidence. Payment history, lease compliance, the condition of the space and the tenant’s business all matter.
- Compare renewal with vacancy on total cost. Downtime, concessions, commissions and re-leasing risk belong in the comparison.
- Write down what you agree. A signed renewal or amendment protects both sides, and accepting rent under unclear terms can create problems.
Start With the Lease
Before you plan anything, gather the current lease and every amendment. Note the key dates and terms:
- Expiration date and any renewal deadline.
- Renewal option language. If the tenant has a right to renew, the lease usually says how and by when it must be exercised and how the renewal rent is set, for example at a fixed amount, at fair market value or by an index. If there is no option, renewal is an open negotiation. See our commercial lease negotiation guide for landlords for how renewal rent clauses work from the owner’s side.
- Rent and escalations. A rent increase during a fixed term usually has to come from an escalation clause or from an amendment both sides sign.
- Holdover provisions. What the lease says if the tenant stays after expiration.
- Other terms that carry into a renewal: guarantees, the security deposit, tenant improvements, exclusive use, and rights on adjacent space.
If any of this is unclear, ask your attorney before you open the conversation.
Assess Tenant Performance
A renewal decision should rest on how the tenant has actually performed. Review the file before you form a view.
| What to review | Where it comes from | Why it matters |
|---|---|---|
| Payment history, late payments, notices sent | Rent ledger | Shows reliability and how much management time the tenant takes |
| Compliance with the lease | Lease and correspondence | Use, insurance, alterations and other obligations |
| Condition of the space | Inspection or site visit, per the lease | Compares condition with what the lease requires |
| Maintenance and repair requests | Property records | Shows how the space is used and how the relationship has worked |
| Operating expense and reconciliation issues | Statements and any disputes | Flags disagreements likely to resurface in renewal talks |
| Business health | Updated financial information the tenant can provide, sales reports if rent includes a percentage | Indicates whether the tenant can carry the next term |
| Role in the property | Rent roll and lease terms | Anchor or key tenants may affect other leases, such as co-tenancy clauses |
| Guarantor status | Guaranty and financial information | Credit support may need to be renewed or updated |
Apply the same questions to every tenant. If the review turns up concerns, decide whether they can be fixed in the renewal terms or whether they point to letting the lease end.
Compare Renewal With Vacancy
Losing a tenant can mean lost rent, a longer vacancy and more expense finding and screening a replacement. Retention has its own costs, such as concessions and improvements. A sound decision compares both paths over the same period.
| Renew | Re-lease the space | |
|---|---|---|
| Rent | Renewal rent over the new term | Rent from a new tenant, starting after downtime |
| Downtime | Little or none | Months without rent, which depend on the market and the space |
| Concessions | Any free rent or allowance offered to keep the tenant | Concessions a new tenant is likely to ask for |
| Improvements | Allowance or work for the current tenant | Work to prepare the space for a new tenant |
| Costs while vacant | None | Taxes, insurance, utilities and maintenance you carry |
| Transaction costs | Legal and drafting | Marketing, brokerage, legal and screening |
| Risk | Tenant’s ongoing ability to pay | Time to find a tenant, and that tenant’s credit and fit |
| Effect on the property | Stable rent roll | Possible effect on other tenants, financing or value |
To use the table, estimate each line for each path, ideally with your broker’s view of current market conditions and recent signed leases. Then compare total value over the term rather than headline rent. Our commercial lease negotiation guideshows why two offers with the same base rent can differ. If you decide to re-lease, see our guide to screening a replacement tenant.
No method guarantees an outcome. The comparison helps you see what each choice requires you to accept.
Rent Increases, Notices and Deadlines: What Governs What
Commercial rent increases and renewal notices depend on the type of tenancy and on the lease. The table below gives a general picture for California. It summarizes sources named in the claim register and is not legal advice. An attorney can confirm what applies to a specific lease.
| Situation | What generally governs | What to check |
|---|---|---|
| Fixed-term lease with scheduled increases | The lease’s escalation clause | Amount, timing and any notice the lease requires |
| Fixed-term lease with no escalation | The lease | Rent usually stays the same until the term ends unless both sides agree to change it |
| Tenant holds a renewal option | The option terms in the lease | Exercise deadline, delivery method, how renewal rent is set |
| Lease expires, tenant stays, owner accepts rent | The lease, plus California’s presumption that continued possession with accepted rent renews the tenancy on the same terms, for no more than a month if rent is monthly (Civil Code section 1945) | Holdover clause, and how your rent acceptance practices could be read |
| Month-to-month commercial tenancy | Statute and any lease terms | For “qualified commercial tenants” (a defined group of small businesses), California’s SB 1103, effective 1 January 2025, requires written notice of at least 30 days for a rent increase of 10% or less and at least 90 days for an increase above 10%, measured against rent charged in the prior 12 months. Termination notice rules also changed. |
| Residential rentals | Separate residential statutes, including California’s rent cap law (AB 1482) | These rules apply to residential property and do not apply to commercial leases |
Two cautions apply. First, SB 1103 is aimed at qualified commercial tenants in month-to-month or shorter tenancies, and it has its own definitions and conditions, so check whether a tenant qualifies. Second, the dates in a lease, not a rule of thumb, set the renewal timeline.
Build Your Timeline From the Lease
If the lease sets deadlines, those come first. Where it does not, work backward from the expiration date:
- How long would it take to find and sign a replacement tenant if this one does not renew?
- How long does the tenant need to decide?
- How long might negotiation take?
For illustration only, if you expect re-leasing to take four months and you want to allow the tenant one month to respond, your proposal would need to go out at least five months before the lease ends. Your numbers will differ. Starting early gives both sides room to negotiate and gives you options if the tenant declines.
Prepare for the Renewal Discussion
Set your objectives. Decide what you want on rent, term and concessions, which terms are must-haves, and the point at which you would let the lease end.
Know your market. Base your position on recent signed leases for comparable space, not only on asking rents, and consider how your building’s condition, parking, visibility and access compare. A broker with current data can help.
Plan your options. Renewal on the same terms, renewal with changes, a short extension, or letting the lease expire each solve a different problem.
Anticipate what the tenant may ask for. Tenants commonly raise rent, term, improvements, free rent, expansion or reduction of space, the right to sublease or assign, and early termination. Knowing your answers in advance makes the conversation easier.
See the tenant’s side. A rent increase affects the tenant’s occupancy cost against its revenue. A move would also cost the tenant build-out, downtime and disruption for customers and staff. Long-standing tenants with a good record may feel an increase is unfair, and the way you explain it affects how it is received.
Communicate clearly and professionally. Explain the reasons for any change, give as much notice as the lease and applicable law allow, listen to concerns and be open to negotiation while protecting your interests.
Consider incentives where they make sense. For commercial tenants, incentives typically take the form of rent abatement, a tenant improvement allowance, flexible term or expansion options, in exchange for a longer commitment or stronger credit support. Weigh each against its cost in the renewal-versus-vacancy comparison. Retention also depends on how you manage the property between renewals: responding to maintenance issues quickly and communicating regularly make a renewal conversation easier.
Document What You Agree
Renewal or extension? A lease renewal is a new lease for another term. An extension continues the existing lease for a further period, usually by amendment. Either way, put the agreement in writing before the old term ends.
A renewal lease or amendment should cover:
- the parties, the premises and the new term,
- base rent, escalations and any percentage rent,
- concessions such as free rent and improvement allowances, and the work to be done,
- operating expense terms and any changes,
- whether renewal options remain, are removed or are modified,
- the guarantee, confirming it continues or is replaced,
- the security deposit, including any change,
- repair and maintenance responsibilities and the condition of the space,
- permitted use, insurance and other changed terms,
- effective dates and signatures from all parties.
Keep the correspondence and drafts that led to the agreement. Make sure earlier amendments are consolidated or referenced so nothing is lost. During negotiation, be aware that accepting rent after a lease expires without a signed agreement can create a month-to-month tenancy on the old terms (see the table above). Have your attorney prepare or review the documents.

FAQs
What is the difference between a lease renewal and a lease extension?
A renewal means signing a new lease for another term while the tenant stays in the space. An extension continues the existing lease for a further period, usually by amendment, without a new lease. Which is better depends on how much of the original lease you want to keep.
When should an owner start the renewal process?
There is no single date. Start from the lease’s own deadlines, then allow for how long re-leasing would take, how long the tenant needs to decide and how long negotiation may take. Starting early gives more options.
Can an owner raise rent during a lease term?
Only if the lease allows it, for example through escalation clauses, or if both sides agree to an amendment. Month-to-month tenancies follow different notice rules, described above.
What are the legal requirements for a commercial rent increase?
They depend on the lease and the type of tenancy. For California month-to-month tenancies with qualified commercial tenants, SB 1103 sets notice periods of at least 30 or 90 days, depending on the size of the increase. Residential rent caps do not apply to commercial leases. Have your attorney confirm what applies to your lease.
What happens if the lease ends and the tenant stays?
The lease’s holdover clause is the starting point. Accepting rent after expiration, without a new agreement, can lead to a presumption that the tenancy continues on the same terms, so decide how you will handle it before the lease ends.
How can an owner handle a tenant’s objections to a rent increase?
Explain the reasons for the increase, show the market information you relied on, listen to the tenant’s concerns, and consider alternatives such as a longer term, a phased increase or a concession in exchange for another term. Follow notice requirements and put any agreement in writing.
Conclusion
Renewal decisions go better when you prepare: know your lease, assess the tenant on evidence, compare renewal with vacancy on total cost, and document what you agree. No preparation guarantees an outcome, but it lets you decide with clear information. For questions about a renewal, call or schedule a free consultation with Tolj Commercial.
