What happens if a landlord misses the CAM reconciliation deadline?

The consequence depends entirely on the lease language. Some leases say a statement delivered after the deadline is 'non-binding' on the tenant — meaning the tenant can ignore the true-up demand entirely. Others say the landlord 'waives' the right to collect any additional amount for that year. A few leases simply allow late statements without consequence. Read the lease's reconciliation clause before assuming anything. If you're a landlord who has missed the deadline, consult your attorney before sending a late statement — you may inadvertently confirm the waiver in writing.

How long is the typical tenant audit window after receiving a CAM statement?

The most common window in commercial leases is 12 months from statement delivery. Some leases specify 6 months, and some give 18–24 months. Retail leases negotiated by large national tenants often have 24-month audit windows. The window is triggered by statement delivery — not by when the tenant reads it or pays the true-up. Landlords should use certified mail or email with read receipt to establish the delivery date precisely. If the window has passed, the statement is typically final and binding.

Do CAM reconciliation deadlines differ by state?

The lease sets the deadline — state law rarely mandates a specific CAM reconciliation timeline for commercial properties. Where state law does matter is in the absence of a lease provision: if the lease is silent on the audit window, courts apply the general contract limitations period (typically 3–6 years depending on the state). By way of example: California and Texas have 4-year written contract limitations periods; New York has 6 years; Illinois and Florida have 5 years. These periods are illustrative — confirm the current statute in the applicable jurisdiction before relying on them. If your lease has a specific window, that window controls regardless of the state's default period.

What is a 'correction window' and how does it work?

A correction window (sometimes called a 'true-up period' or 'adjustment period') is the timeframe after a landlord discovers an error in a prior-year statement during which they can issue a correction. Many leases limit corrections to the same audit window — if a tenant has 12 months to dispute, the landlord also has 12 months to correct a billing error in their own favor. Without this symmetry, a landlord who discovers they under-billed in 2023 might try to collect three years later — which most tenants would reject as inequitable.

How should I schedule the reconciliation process to hit all deadlines?

Work backward from your statement deadline. If the lease requires statements by April 30 for a December 31 year-end, your milestones are: January 15 — GL export and account mapping complete; February 15 — pool calculations, gross-up, cap math complete; March 15 — tenant statements drafted and reviewed internally; April 1 — statements delivered with two weeks of buffer. Properties with 50+ tenants may need to start earlier. The buffer matters because late-arriving vendor invoices and year-end accrual adjustments from your accounting team often land in January and February.

CAM Reconciliation Timeline Guide: Deadlines, Notices, and Correction Windows

By Angel Campa·Founder, CapVeriUpdated April 24, 2026

Quick Answer

Most commercial leases require CAM reconciliation statements within 90–120 days of year-end (April 30 for December 31 properties). The tenant's audit window is typically 12 months from statement delivery. Landlords who miss their deadline risk losing the right to collect a true-up amount — the consequence depends on the specific lease language.

Why Timing Is as Important as Math

CAM reconciliation has two ways to go wrong: bad math and missed deadlines. A perfectly accurate statement delivered 30 days late can cost a landlord the right to collect $50,000 in true-up billings. A deadline-compliant statement with a denominator error creates a dispute that takes months to resolve.

This guide covers the timing side — what deadlines apply, how they interact, and how to build a workflow that hits every date.

For the calculation side, see CAM expense reconciliation process and CAM reconciliation checklist.

Standard Timeline: December 31 Year-End Properties

Most commercial properties use a calendar year reconciliation period. Here's the standard timeline:

Milestone	Typical Date	Range
Reconciliation period ends	December 31	—
GL export available	January 10–15	January 5–31
Accounting team closes books	January 15–31	January 10 – February 15
Property manager starts reconciliation work	February 1	January 15 – February 15
Statement drafts complete	March 1	February 15 – March 31
Internal review and QC	March 15	March 1 – April 15
Statement delivery deadline	March 31 – April 30	90–120 days after year-end
Tenant payment due	30 days after delivery	15–45 days
Tenant informal review window	30–60 days	Per practice
Tenant audit rights deadline	12 months after delivery	6–24 months

Properties with other fiscal year-end dates follow the same relative timeline — March 31 year-end means statements by June 30, audit window closes June 30 of the following year.

Lease-Type Timing Variations

Retail (Strip Center and Mall)

Retail leases — especially those with national tenants — tend to have the most contractually specific timing requirements:

Statement deadline: 90–120 days (April 30 for December 31 year-end)
Tenant payment: 30 days from statement
Audit window: 12–24 months (national anchors often negotiate 18–24 months)
Landlord document production (after audit request): 30–45 days

National tenant leases often include a "deemed correct" provision: if the tenant doesn't exercise audit rights within the window, the statement is final and binding regardless of errors. These provisions are enforceable — don't miss the deadline.

Office Buildings

Office leases generally have more flexibility in timing but also more room for negotiation in the original lease terms:

Statement deadline: 120–180 days (common in Class A office)
Tenant payment: 30 days from statement
Audit window: 12 months (standard), sometimes 6 months in shorter leases
Landlord document production: 30–60 days

Class A office tenants increasingly request 60-day advance notice before the audit window closes as a reminder provision — some landlords agree to this in lease negotiations.

Industrial / Flex

Industrial leases often use simpler gross lease or modified gross structures. Where NNN or CAM-pass-through leases exist:

Statement deadline: 90–120 days
Tenant payment: 30 days
Audit window: 12 months (often not specifically negotiated — defaults to lease language)

Industrial tenants dispute CAM less frequently than retail tenants, but when they do, it's often because a capital item (dock leveler replacement, major roof repair) was included in operating CAM.

What Triggers Each Clock

Statement Delivery → Audit Window

The audit window starts when the statement is "delivered" per the lease's notice provisions. Most leases define notice as:

Hand delivery to tenant's on-site address
Certified mail — effective on delivery date (not mailing date)
Email — effective on send date (if the lease permits email notice)
Overnight courier — effective on the business day after sending

Landlords who send statements by first-class mail without confirmation are creating an ambiguity. If the tenant later claims they didn't receive the statement, the landlord can't prove the audit window has closed.

Best practice: Send via certified mail or email with read receipt. Log the delivery confirmation with the statement in your property files.

Audit Request → Document Production

When a tenant exercises audit rights, they send a written notice. From that date:

Landlord must produce documents within the lease-specified period (typically 30–60 days)
If documents are late or incomplete, the tenant's audit window typically pauses (some leases explicitly extend it)

Document Production → Audit Completion

Tenants typically have 30–90 days after receiving documents to complete their audit review. Some leases set a hard deadline; others leave it open. If the lease doesn't specify, completing the audit within 90 days of document production is a reasonable standard.

Correction Windows: Landlord and Tenant

Landlord Self-Correction

If a landlord discovers they under-billed a tenant — for instance, finding they accidentally excluded a utility account — most leases allow the landlord to issue a corrected statement within the same window that applies to the tenant's audit rights. If the tenant has 12 months to dispute, the landlord typically has 12 months to correct.

After that window, most courts will not enforce a landlord's corrected billing over the tenant's objection, especially where the tenant has already relied on the original statement amount.

Tenant-Initiated Correction

A tenant who exercises audit rights and finds errors has the ability to demand a corrected statement and a credit or refund. The timeline for the landlord to issue the credit is typically 30–60 days from the date the dispute is resolved (by agreement or arbitration award).

Calendar Year vs. Lease Year

A property with mixed lease year definitions is harder to manage:

Tenant A: December 31 year-end (calendar year CAM)
Tenant B: June 30 year-end (fiscal year CAM)
Tenant C: Lease anniversary date CAM

For Tenant B, the reconciliation year is July 1–June 30. Statements are due within 90 days of June 30 — so September 30. The audit window closes September 30 of the following year.

Most property management systems handle multiple reconciliation periods, but make sure each tenant's record has the correct year-end date. An error here sends the wrong statement for the wrong period.

Building a Deadline Calendar

For a property with 40 tenants and three different lease year-ends, maintain a rolling deadline calendar with:

Each tenant's reconciliation year-end date
Statement delivery deadline (year-end + 90 or 120 days per lease)
Tenant payment due date (statement + 30 days)
Audit window closing date (statement delivery + 12/18/24 months per lease)
Prior-year audit status (any pending disputes)

Flag statements as "delivered" with the date in the calendar when you send them. This is the record you'll need if a tenant disputes whether their audit window has closed.

What Happens When Deadlines Are Missed

Who Misses	What Happens
Landlord (statement late)	Tenant may reject true-up demand; depends on lease language
Tenant (audit request late)	Statement deemed final and binding; tenant loses right to dispute
Landlord (document production late)	Tenant's audit window typically tolled/paused
Tenant (audit completion late)	Findings may be rejected; landlord can declare statement final

Missing any of these deadlines creates leverage for the other party. For landlords who've missed their statement deadline, see cam reconciliation letter tenant guide for guidance on how to handle a late statement carefully.

For tenants approaching the end of their audit window, the cam reconciliation dispute letter guide covers how to formally preserve your rights before the deadline expires.

Using CapVeri to Manage Timelines

CapVeri tracks statement delivery dates and audit window expirations at the tenant level. When you generate a statement in the platform, the delivery timestamp is logged automatically. The dashboard surfaces upcoming audit window deadlines 60 and 30 days before expiration.

The cam reconciliation checklist integrates with the platform's deadline tracking so each step has a target completion date tied to your statement delivery deadline.

Use the audit risk quiz to assess whether your current timeline and documentation process creates unnecessary dispute exposure.
