Compare the executed commercial lease against the exact draft the tenant approved, not simply the most recent file in the folder. Reconcile the document package, run a text comparison, and verify potentially material differences against the signed pages, schedules, and exhibits. Trace each change through rent, operating costs, occupancy rights, and notice provisions. The deliverable is a version comparison checklist separating confirmed deviations, presentation changes, and unresolved evidence gaps, with a tenant decision owner and documented disposition for each material issue.

When to use this workflow

Use this workflow when tenant counsel or an in-house legal team receives a signed lease package, discovers competing “final” versions, or prepares an execution-confirmation report. It also applies when a signed work letter or rent schedule arrives separately.

The task is to establish what changed between approval and execution—not renegotiate every provision or produce a complete lease abstract. Identify later amendments separately: they may affect the current obligations without explaining what changed at execution.

This guide addresses US commercial leasing. Evaluate legal consequences under the property’s jurisdiction, applicable law, tenant use, and actual wording. The cited leases illustrate negotiated provisions, not market standards; the New York statute has a limited, state-specific scope.

What you need

Collect these inputs before comparing text:

  • The exact approved draft, its exhibits, and approval evidence identifying the file and any approval conditions.
  • The received executed package, including signature pages, handwritten edits, work letter, premises plan, rent schedule, guaranty, and incorporated attachments.
  • Transmittal correspondence, execution instructions, and available signing records connecting signatures to the document package.
  • Amendments, side letters, and commencement certificates, identified separately by date and relationship to the lease.
  • The tenant’s intended use, occupancy assumptions, approved economics, and internal negotiation checklist, including authorized approvers.

Assign stable document IDs. Distinguish the approved Word file from its approval PDF; check rendering rather than assuming they match. Preserve received originals and compare working copies. Record missing evidence before describing either package as complete.

Use the template

Use the Commercial Lease Agreements — Version comparison checklist below. You can copy this table into your working document or spreadsheet. Create one row per distinct deviation or evidence gap.

ID / topic Draft source Executed source Verified difference Effect / priority Evidence status Action / owner Disposition

In each source column, enter the document ID, clause, and page. For schedules, add the row, column, or spreadsheet cell reference. Keep operative excerpts short; retain longer extracts and calculations in an identified working note.

“Evidence status” distinguishes confirmed text, illegible text, missing attachments, and unresolved interpretation. “Effect / priority” explains the tenant consequence and relevant dependencies, not merely a color rating.

“Disposition” identifies whether the difference is explained, accepted by an authorized decision-maker, awaiting correction, or open. Include the decision date and supporting approval reference when closing an item. A comparison-tool result alone is not verification.

Step by step

1. Establish the approved baseline and execution package

Identify the draft actually authorized for signature. Match approval correspondence to the filename, attachments, and remaining conditions. A later clean copy may contain unapproved changes; an earlier redline may omit a concession approved by email.

Inventory the received signed package by document ID and page count. Match referenced exhibits to attachments, checking labels and premises-plan revisions. Inspect signature blocks for party identity and capacity, while separately checking attachment completeness. If parties signed different counterparts, compare their substantive pages before treating them as one package.

Record: baseline IDs, approval uncertainty, package discrepancies, and the person responsible for each gap.

2. Generate the comparison and inspect difficult content

Run the text comparison on working copies. For scans, compare extracted text while retaining page images as the verification source. Inspect tables, footnotes, checkboxes, handwritten revisions, and embedded plans separately.

Check changed numbers and negatives against the image. An OCR omission of “not,” a misplaced decimal, or reordered table rows can create a false deviation. Conversely, a revised boundary on a premises plan may never appear in a text redline. Check both draft markup and the clean text intended for execution; unresolved tracked changes can otherwise distort the baseline.

Record: each suspected difference, both source locations, and whether visual inspection confirms it. Label unreadable content as unreadable, not absent.

3. Separate substantive changes from presentation changes

Classify verified differences as economics, premises and operations, risk allocation, timing and notices, execution, or presentation. Treat renumbering as presentation only after checking cross-references.

Compare each departure with approval conditions and the tenant’s internal checklist. Route changed insurance requirements to the risk team and reduced electrical capacity to facilities where appropriate. Neither is immaterial merely because base rent is unchanged.

Keep two questions separate: does the executed wording depart from the approved bargain, and is that departure legally or commercially acceptable? An explanation of how a change occurred does not itself establish tenant approval.

Record: reasoned priority, approval dependency, and reviewer. Close presentation-only items with a brief explanation.

4. Reconcile rent and additional-rent changes

Compare every rent period, amount, unit, commencement trigger, abatement condition, and partial-period convention. Recalculate affected periods in a checked spreadsheet or independently verified calculation. Do not replace stepped rent with an assumed annual escalator: the Arhaus lease, § 1.02(B) illustrates multiyear rent steps rather than a stated annual percentage increase.

For operating expenses, compare definitions and exclusions alongside caps. Check whether a changed allocation share, excluded category, or comparison year changes the tenant’s protection. Distinguish a cap on controllable expenses from protection against total occupancy-cost increases.

Record: changed schedule coordinates, verified arithmetic, assumptions, and finance reviewer. State missing budget or measurement questions rather than inventing estimates.

5. Trace operational and risk-allocation changes

Review changed premises boundaries, permitted use, access, delivery requirements, improvement approvals, transfers, repairs, insurance, indemnity, casualty, default, and surrender terms. Follow changed definitions and cross-references into otherwise unchanged provisions.

For repairs, distinguish who performs work from who ultimately pays. Trace expense-recovery provisions before concluding that a landlord obligation protects the tenant from the cost. Reconcile the work letter with the lease body and any order-of-precedence provision.

For covered public accommodations, contractual ADA allocation operates between landlord and tenant without eliminating their external compliance responsibility. Assess coverage and applicable obligations rather than treating every commercial tenancy identically; see DOJ guidance, III-1.2000.

Record: affected operations or components, linked clauses, interpretation questions, and responsible reviewers.

6. Compare notice mechanics and timing consequences

Check extension elections, nonrenewal provisions, commencement confirmations, reconciliation objections, and cure provisions. Compare periods, triggers, delivery methods, recipients, required copies, and receipt-versus-dispatch wording.

The SurveyMonkey lease, paragraphs 2.2 and 3.3.2 illustrates a contractual consequence for not returning a requested commencement letter within 30 days and an extension-election window of 450–360 days before expiration. These are examples, not default rules; eligibility conditions and notice provisions also matter.

Distinguish affirmative options from automatic renewal. New York General Obligations Law § 5-905 makes the specified automatic-renewal provision inoperative unless the landlord alerts the tenant in writing 15–30 days before the contractual nonrenewal deadline, personally or by registered or certified mail. It does not establish a universal affirmative-option deadline.

Record: changed actor, action, trigger, deadline, and delivery requirements. Assign unresolved trigger dates; do not assume them.

7. Resolve deviations and issue the comparison report

Review confirmed material departures with the appropriate tenant approver. Distinguish an explanation supported by contemporaneous approval records from a newly accepted risk. Counsel should determine whether corrective documentation is appropriate and what authorization it needs, considering the signed language, governing law, and circumstances.

Do not edit the signed lease to resemble the approved draft. Keep proposed corrective language separate and preserve the original comparison. Internal acceptance records a tenant decision; do not describe it as changing the parties’ agreement.

Record: decision, supporting evidence, approver, and outstanding action. Deliver the checklist with a concise summary of material departures and gaps. If completeness remains unverified, state that limitation rather than reporting an unqualified match.

Worked example

Fictional scenario: Cedar Quay Analytics LLC approves a five-year office lease with Harbor Lantern Properties LLC. All parties, documents, amounts, and terms in this example are fictional. Draft D-04 and execution package E-01 describe 12,000 square feet. Approval evidence authorizes monthly base rent of $24,000 for months 1–12 and $25,000 for months 13–24; later periods are unchanged. D-04 also excludes roof replacement from operating expenses and includes premises plan B-3 as Exhibit B.

In E-01, the rent table instead specifies $24,000 for months 1–11 and $25,000 for months 12–24. The roof exclusion is deleted. Exhibit B is referenced but missing from the received package.

ID / topic Draft source Executed source Verified difference Effect / priority Evidence status Action / owner Disposition
01 / Base rent D-04, § 3, p. 4, rows 1–2 E-01, § 3, p. 4, rows 1–2 Higher rate begins month 12, not 13 $1,000 additional rent for a full month; high Text confirmed visually; no approval located Counsel: check approvals and seek resolution Open; not accepted
02 / Roof cost D-04, § 6.2, p. 9 E-01, § 6.2, p. 9 Roof-replacement exclusion deleted Possible additional rent; amount unknown; high Deletion confirmed; recovery scope unresolved Counsel/finance: trace capital-cost provisions Open; no supported estimate
03 / Premises plan D-04, Exhibit B, plan B-3, p. 22 E-01, § 1, p. 2; attachment unavailable Referenced plan cannot be compared Boundaries unverified; high Missing evidence, not confirmed changed plan Transaction lead: obtain execution attachment Comparison incomplete

The first entry identifies a one-month rate difference, subject to abatement and partial-month provisions—not five years of increased rent. The second requires analysis of capital-cost recovery before concluding that replacement costs are chargeable. The third prevents confirmation of matching premises but does not prove a boundary change.

The decision changes from filing an apparently matching lease to resolving two deviations and completing the package. Any proposed correction remains separate from the received execution record.

Common mistakes

  • Comparing against the latest filename. Establish approval through correspondence, attachments, and conditional concessions.
  • Treating a clean text comparison as complete. Inspect plans, signatures, handwriting, tables, and exhibits separately.
  • Checking rent amounts without triggers. Compare delivery, commencement, abatement, and rent-period definitions together.
  • Treating an unchanged expense cap as unchanged protection. Review exclusions, allocation shares, and definitions determining its scope.
  • Calling missing evidence a deletion. Separate unavailable attachments from confirmed omissions and assign collection responsibility.
  • Repairing the signed file directly. Preserve the executed record and route corrective drafting through counsel and authorized approvers.

Final quality check

  • Baseline and execution documents have stable IDs and documented provenance.
  • Referenced exhibits are matched or expressly listed as missing.
  • Material differences are verified against source pages, not OCR alone.
  • Rent changes have checked arithmetic and stated assumptions.
  • Changed definitions, cross-references, and notice mechanics have been traced.
  • Legal propositions have verified source support within the source’s jurisdictional or contractual limits.
  • Every material issue has an authorized disposition or named owner and next action.
  • The report distinguishes deviations, accepted risks, evidence gaps, and interpretation questions.

Frequently asked questions

What if the approved draft cannot be identified?

Compare plausible candidates, but label the baseline unresolved. Seek approval correspondence and participant confirmation. Do not call a difference unauthorized solely because it departs from one candidate.

Should we compare every negotiation draft?

Start with the approved draft. Consult earlier versions to explain disputed changes or reconstruct approval history, not to replace the authorized baseline.

Does every difference require corrective documentation?

No. Close presentation changes after checking references. Substantive departures need an authorized decision; corrective documentation depends on wording, facts, and governing law.

How should a later commencement certificate be handled?

Compare it separately with the lease’s commencement mechanism and approval evidence. Record supplied dates, conflicts, and uncertainties. Preserve the original draft-to-execution findings.
