Final reconciliations arrive 3 to 6 months post-expiration, audit rights survive the lease end date, and landlords sometimes inflate post-expiration true-ups to consume your security deposit. Audit the final statement before releasing your deposit, and preserve your rights in writing.
CAM True-Up at Lease Expiration: A final Common Area Maintenance reconciliation covering the tenant's last period of occupancy, delivered after the lease expires. The tenant remains liable for any balance shown, subject to audit rights that typically survive lease expiration.
40% of commercial CAM reconciliations contain material billing errors (Tango Analytics, 2023)
"After testing reconciliation samples from published audit cases through CAMAudit, post-expiration statements are where we flag the most pro-ration errors. A landlord billing a full year of CAM on a lease that ended June 30 is a textbook overcharge. On a $60,000 annual CAM pool, that is a $30,000 error that gets silently absorbed by the security deposit." — Angel Campa, Founder of CAMAudit
Moving out does not always end your CAM exposure. Most commercial leases entitle the landlord to a final CAM reconciliation covering the portion of the last year you occupied the space. That reconciliation often does not arrive until 3 to 6 months after your lease expires.
This creates a post-expiration liability that surprises many tenants. You left the space, returned the keys, and assumed your obligations were done. Then a reconciliation arrives claiming $8,000 in additional CAM for your final year.
This article covers what you owe, what you do not owe, and how to protect yourself at lease expiration.
Most commercial leases require the landlord to deliver the annual CAM reconciliation within 90 to 180 days after the end of each calendar year (or fiscal year, depending on your lease). If your lease expires mid-year or at year-end, the landlord typically has the same deadline to deliver the final reconciliation.
The timing creates a gap:
Under most leases, you still owe the balance shown on that reconciliation, subject to your audit rights and any disputes.
The final reconciliation should cover only your period of occupancy:
The pro-ration method varies by lease. Most apportion on a per-day basis. Others use monthly fractions. Review your lease's reconciliation provision for the applicable method.
Common error: landlords calculate the annual CAM and bill the tenant for the full year, even when the tenancy ended mid-year. This is an overcharge equal to the amount attributable to the unoccupied portion.
Many commercial leases give the landlord the right to apply the security deposit to outstanding CAM obligations, including final reconciliation amounts. The sequence typically works as follows:
Problems arise when:
The landlord holds the deposit and delivers the reconciliation late. If the landlord has not delivered the reconciliation within the required window, they cannot simply continue holding the security deposit indefinitely. The lease should specify deadlines for reconciliation delivery and deposit return.
The landlord inflates the reconciliation to consume the security deposit. Post-expiration reconciliations are fertile ground for overcharges because the former tenant is less engaged and may not audit the final statement. The deposit makes the overcharge invisible: the tenant just gets less money back and may not investigate why.
The deposit does not cover the reconciliation balance. If the final CAM balance exceeds the deposit, the landlord can pursue the balance through collection. This is a real risk if actual CAM was significantly higher than estimated monthly payments.
This is where many tenants are surprised: audit rights typically survive lease expiration. The right to audit CAM charges is a lease covenant, and absent language terminating it at expiration, it remains effective for the period specified in the clause.
A typical clause says: "Tenant shall have the right to audit CAM charges for any period within 24 months following receipt of the applicable reconciliation statement."
If the reconciliation is delivered April 30 after your December 31 lease expiration, you have until April 30 two years later to exercise the audit right (under a 24-month window).
Request a preliminary final-year estimate. Before your lease expires, ask the property manager for their estimate of annual CAM for the final year. This helps you anticipate the reconciliation amount.
Document the deposit amount and return deadline. Note the deposit amount held, any applicable interest, and your lease's deadline for deposit return.
Review the reconciliation window. Know the landlord's deadline to deliver the final reconciliation. If they miss it, that affects their ability to collect.
Confirm the pro-ration method. For partial-year final occupancy, verify the method for calculating your share.
Preserve access to your lease documents. Keep your signed lease, all amendments, prior reconciliations, and correspondence. You may need these to dispute a post-expiration reconciliation.
Don't release all claims. If the landlord asks you to sign a release of all claims as part of the lease wind-down, read it carefully. A broad release could waive your right to dispute the final reconciliation.
If you believe the reconciliation is incorrect, respond in writing within your lease's dispute window. Do not simply ignore the reconciliation.
For disputed amounts:
The landlord can pursue unpaid post-expiration CAM through:
Lease expires June 30. Annual CAM per full-year calculation: $60,000.
Correct final-year charge (6 months): $60,000 / 12 x 6 = $30,000. Monthly estimated payments made January through June: $4,500/month = $27,000 paid. Correct reconciliation balance: $30,000 - $27,000 = $3,000 due.
Landlord reconciliation claims: Full-year CAM = $60,000. Payments = $27,000. Balance: $33,000.
The landlord billed for the full year on a lease that ran only 6 months in the final year. Overcharge: $30,000 (the second half of the year you did not occupy).
Security deposit: $25,000. Landlord applies the deposit against $33,000 and demands $8,000 more.
Your correct position: $3,000 owed, $25,000 deposit should yield $22,000 return after the $3,000 offset.
Check your lease's reconciliation delivery deadline. If the lease requires delivery within 120 days of year-end and the landlord missed that, you may have a defense against the reconciliation charge. Some leases explicitly provide that late delivery forfeits the landlord's right to collect additional amounts.
Your lease should specify the deposit return deadline, typically 30 to 90 days after lease expiration. If the landlord is waiting for the final CAM reconciliation before returning the deposit, check whether your lease permits this. Some leases allow withholding pending reconciliation; others require return on a set schedule.
The dispute window typically runs from receipt of the reconciliation, not from lease expiration. So if the reconciliation was delivered in May (5 months post-expiration) and your window is 18 months, you have until November of the following year to file a dispute.
It depends on the language. If the termination agreement includes a mutual release of all claims, it may bar CAM disputes. If it only terminated your occupancy obligations and said nothing about reconciliation disputes, your audit rights likely survive. Review the specific language of the termination agreement.
Courts generally hold that contractual notice provisions control. If the landlord can prove delivery (certified mail, email with read receipt), the clock starts from that delivery date regardless of when you actually reviewed it. Update your contact information with the property manager and forward any mail from the property address for at least 6 months post-move-out.
CAMAudit's detection engine analyzes final-year reconciliations for pro-ration errors and flags any reconciliation amounts that include periods beyond the lease termination date.

Can a landlord send a CAM true-up months after my lease expires?
Yes. Most commercial leases entitle the landlord to a final CAM reconciliation covering the portion of the last year you occupied the space, with the same delivery deadline that applies to annual reconciliations, typically 90 to 180 days after year-end. If your lease expires December 31, the landlord may have until April 30 of the following year to deliver the final statement. Under most leases, you still owe any balance shown, subject to your audit rights and any disputes.
Does my landlord owe me a pro-rated final-year CAM reconciliation if I moved out mid-year?
Yes. The final reconciliation should cover only your period of occupancy. For a lease ending June 30, only the January-through-June CAM should be billed. The pro-ration method varies by lease: most apportion on a per-day basis, others use monthly fractions. A common overcharge is billing the full annual CAM on a lease that ran only half the year. In the dollar example in this article, that error turned a $3,000 true-up into a $33,000 demand, a $30,000 overcharge.
Do my audit rights survive after the lease expires?
Typically yes. Audit rights survive lease expiration absent specific language terminating them at expiration. A clause that says 'Tenant shall have the right to audit CAM charges for any period within 24 months following receipt of the applicable reconciliation statement' continues to operate even for post-expiration reconciliations. If the final reconciliation is delivered 5 months after expiration and your window is 24 months, you have until 24 months from that delivery date to exercise the right.
Can my landlord keep my security deposit to cover a post-expiration CAM reconciliation?
Many commercial leases give the landlord the right to apply the security deposit to outstanding CAM obligations, including final reconciliation amounts. The problem arises when landlords hold the deposit past the required return deadline while waiting for the reconciliation, or inflate the final reconciliation to consume more of the deposit. Your lease should specify both the reconciliation delivery deadline and the deposit return deadline. Enforcing those deadlines is the primary protection against post-expiration deposit disputes.
What happens if I signed a lease termination agreement? Does that bar me from disputing the final reconciliation?
It depends on the language. If the termination agreement includes a mutual release of all claims, it may bar CAM disputes. If it only terminated your occupancy obligations and said nothing about reconciliation disputes, your audit rights likely survive. Always read the specific language of any termination agreement before signing. A broad release 'of all claims arising under the lease' can inadvertently waive your right to dispute a final reconciliation that has not yet been delivered.
