You Already Signed a Commercial Lease. Now What?

By LeaseLens · April 2026 · 10 min read

Most guides about commercial leases are written for people who haven't signed yet. The advice is sensible: read it carefully, get a lawyer, negotiate before you commit.

But a lot of people find their way to lease guidance after the signature is already on the page. They're in a space, they've been paying rent for months or years, and something has made them want to understand what they actually agreed to. Maybe rent went up more than expected. Maybe they want to expand or sublease. Maybe they're approaching the end of the term and realize they don't know if their renewal option is still valid.

If that's you: this guide is for you. Understanding your lease after signing is not futile. There is real, practical value in knowing exactly what you committed to — your rights, your obligations, your options, and the deadlines that could cost you significantly if you miss them.

The first thing to do: find your renewal deadline

If you do nothing else after reading this guide, do this: find your renewal option notice deadline and put it in your calendar today.

Most commercial leases include a renewal option — your right to extend the lease for another term. Exercising that option is not automatic. You must send written notice to the landlord within a specific window, typically 6–12 months before your lease expires.

Find the renewal option section of your lease. It usually appears under "Option to Renew," "Renewal Rights," or "Extension Options." Read it carefully:

• How many renewal options do you have?
• How many years is each renewal term?
• What is the notice window? (e.g., "not less than 180 days prior to expiration")
• How is renewal rent calculated? (market rate? fixed increase? CPI?)
• Are there any conditions that void the option? (e.g., "tenant must not be in default at time of exercise")

Once you have the notice deadline date, put it in your calendar with reminders at 6 months, 3 months, and 1 month before. This is not a date to discover in a panic.

What you can still negotiate after signing

The lease is signed. That doesn't mean every term is fixed for eternity. Landlords negotiate with existing tenants all the time — especially tenants who are reliable payers, who have tenure in the space, or who have leverage because of the cost to re-lease to someone new.

Renewal terms

If your renewal option says "fair market value," your upcoming renewal is a negotiation. You don't have to accept whatever rent the landlord proposes. Get comparable rates for similar space in the area, bring the data, and negotiate. The landlord knows what it costs to re-lease the space — a short-term reduction is usually preferable to months of vacancy.

Lease modifications and amendments

Any term in your lease can be modified by mutual agreement. Landlords may agree to:

• Adding an early termination option that wasn't in the original lease
• Reducing rent for a period in exchange for a lease extension
• Expanding permitted use language to cover new business activities
• Adding sublease rights that were restricted in the original
• Adjusting TI allowance in exchange for a longer commitment

These conversations are most productive when your business is doing well (you have leverage as a reliable tenant) or when you're approaching a renewal and the landlord wants to keep you.

Understanding your CAM charges and audit rights

If you're in a NNN lease, you've been paying CAM charges in addition to base rent. These are estimated at the start of the year and reconciled annually against actual costs. Many tenants pay these without ever auditing them — and overpayments are more common than you'd expect.

How CAM reconciliation works

Each year, you receive a CAM reconciliation statement from the landlord showing actual costs versus your estimates. If actual costs exceeded estimates, you owe a reconciliation payment. If estimates exceeded actuals, you're owed a credit (or refund).

Most tenants accept these statements without review. But the calculation involves numerous line items — many of which are legitimately excludable from CAM per your lease — and errors or inflations are common.

Your audit rights

Most commercial leases include audit rights — your right to request supporting documentation for CAM charges and have them reviewed. These rights are often limited in time (e.g., "tenant must request audit within 90 days of receiving reconciliation statement").

Find the audit clause in your lease. If it exists and you haven't exercised it recently, review this year's CAM reconciliation carefully. Items commonly found in CAM that may not belong there (per lease definitions): capital expenditures, landlord overhead, depreciation, management fees above the agreed cap, costs from other tenant buildouts.

Your options if you need to exit early

Business circumstances change. A signed lease doesn't mean you're trapped — but your options depend heavily on what's in your lease.

Option 1: Exercise your early termination clause

If your lease has an early termination clause, this is your cleanest exit. These clauses typically require:

• Advance written notice (commonly 6 months)
• A termination fee (commonly 3–6 months of remaining rent)
• No current default at time of exercise

Many leases only allow termination after a certain point in the lease term (e.g., after year 3 of a 7-year lease). Check the exact conditions in your lease before assuming this option is available.

Option 2: Sublease the space

If your lease permits subleasing, you can bring in a subtenant to occupy the space and pay rent. You remain on the hook to the landlord as the original tenant — you collect rent from the subtenant and pay the landlord. If the subtenant defaults or vacates, the obligation comes back to you.

Subleasing works best when market rents have increased since you signed — you may be able to sublease for more than you're paying, generating a profit. When market rents are below your lease rate, you may need to sublease at a loss.

Option 3: Negotiate a lease buyout

In this scenario, you negotiate directly with the landlord to exit the lease. You pay a lump sum (often 6–12 months of remaining rent) in exchange for a full release from your obligations. Landlords are most willing to do this when they have a replacement tenant lined up, when the space is in high demand, or when they want to redevelop the property.

Option 4: Force majeure or legal excuse (rare)

In extraordinary circumstances — government orders, severe landlord breaches, or specific events covered by your lease's force majeure clause — there may be legal grounds to exit or suspend obligations. This requires an attorney to evaluate and is highly fact-specific.

Subleasing: what's allowed and how it works

Find the subletting and assignment clause in your lease (typically titled "Assignment and Subletting" or "Transfer"). This clause controls whether you can sublease, and under what conditions.

Key variables:

• Consent required? — Almost always yes. The question is whether landlord can withhold unreasonably ("reasonably" is better for you).
• Financial review of subtenant? — Landlord can typically require the subtenant to demonstrate financial capacity.
• Profit sharing? — Some leases require you to share any profit from subleasing above your rent with the landlord.
• Your continuing liability? — In a sublease (vs. assignment), you remain liable to the landlord. If the subtenant doesn't pay, you still owe.
• Permitted use restriction? — The subtenant often must operate within your permitted use clause.

If subleasing is permitted with landlord consent that cannot be unreasonably withheld, you're in a reasonable position. Start the conversation with the landlord before finding a subtenant — understanding their approval criteria upfront avoids wasted time.

What the landlord can and cannot do to you

Understanding the landlord's rights under your lease tells you what you need to protect against.

Relocation clause

Some commercial leases include a relocation clause that allows the landlord to move you to comparable space elsewhere in the building. If yours does, the landlord can exercise it — usually with required notice (commonly 60–90 days) — and they must provide comparable space. Check whether your lease has this and what "comparable" means as defined.

Entry rights

Your landlord has the right to enter the premises for inspections, repairs, or showing the space to potential tenants near lease end. Most leases require advance notice (commonly 24–48 hours) except in emergencies. Know what notice your lease requires before assuming unannounced visits are a violation.

What the landlord cannot do

• Lock you out without a court order (in virtually all US jurisdictions)
• Remove your property or equipment without legal process
• Withhold essential services (utilities, HVAC) as a means of pressure
• Retaliate against you for exercising legal rights (e.g., requesting repairs)
• Charge more than the holdover rate specified in the lease

The personal guarantee: what it means now

If you signed a personal guarantee when you signed the lease, your personal assets are on the line for your lease obligations. Understanding the scope of this guarantee — and what would trigger it — is important for how you manage your tenancy.

Key things to understand:

• What it covers: Does it cover just rent, or also CAM charges, damages, and legal fees?
• Does it burn off? Some guarantees reduce or extinguish after a period of on-time payment. Check yours.
• What triggers it: Typically triggered by default on the lease — missed rent, vacating early without a proper exit, or violation of material lease terms.
• Surviving entities: If your business entity fails or dissolves, the personal guarantee survives. It follows you individually.

If your guarantee doesn't have a burn-off and you've been a reliable tenant for 2+ years, this is worth raising in your next lease renewal negotiation. You've earned the track record. Many landlords will agree to limit or release the guarantee at renewal for tenants with good payment history.

How to get a full picture of your lease

If you've been in your space for a while and realize you don't fully understand what you signed, the most efficient thing to do is get a structured analysis of your existing lease.

A LeaseLens analysis of a signed lease delivers the same report as pre-signing analysis — because the lease content is the same. You'll get:

• Your full rent schedule for every remaining year
• Your estimated total remaining occupancy cost
• Every critical deadline — renewal options, termination windows, audit rights
• CAM structure summary including what's included and whether there's a cap
• Your early termination rights (if any)
• Personal guarantee scope
• Risk flags on any landlord-favorable provisions
• Plain-English explanation of every material term

Many of the most important protections in commercial leases — audit rights, holdover caps, sublease rights — have time-based conditions. The sooner you understand your lease, the more of those rights you can actually use.
