Complete lease data entry requires capturing significantly more than tenant name, rent, and expiration date. A thorough abstraction covering all material provisions protects ownership against missed deadlines, billing errors, and disputes over lease obligations. This checklist covers the 14 categories of information that a production lease abstract should capture.
Use this as a verification checklist against any lease entry in your property management system. If a field is blank, ask whether the information was truly absent from the lease or was simply missed.
Category 1: Parties
- Landlord legal entity name — the exact entity name as stated in the lease; must match the signing entity
- Landlord jurisdiction of formation — the state where the landlord entity was formed (Delaware LLC, California LP, etc.)
- Tenant legal entity name — exact legal name; matters for default and enforcement proceedings
- Tenant jurisdiction of formation
- Tenant trade name / DBA — if different from legal entity name
- Guarantor name — personal or corporate guaranty; the guarantor's identity and obligation scope
- Guaranty burn-off provisions — if the guaranty reduces or terminates upon certain conditions (e.g., years of occupancy, financial covenants)
- Landlord notice address
- Tenant notice address
- Broker(s) — both landlord and tenant brokers; relevant for commission disputes
Common error: Using the informal company name instead of the legal entity. "Acme Corp" and "Acme Corporation of Delaware" are different for enforcement purposes.
Category 2: Premises
- Property address
- Suite or unit number
- Floor(s) occupied
- Rentable square footage — the RSF as stated in the lease
- Usable square footage — if disclosed
- Load factor / add-on factor — the ratio of RSF to USF
- Premises legal description — particularly for ground leases or leases with complex premises definitions
- Common areas included — any specific common areas the tenant has exclusive or priority use of
- Parking — number of spaces, type (reserved vs. unreserved), location, and cost
- Storage — any storage space, square footage, and whether it is included in RSF
Common error: Accepting the landlord's RSF figure without verifying against the BOMA measurement methodology specified in the lease.
Category 3: Lease Term
- Lease commencement date
- Rent commencement date — if different from commencement (free rent period)
- Lease expiration date
- Lease term in months
- Free rent period — months of free base rent, and whether CAM continues during free rent
- Holdover provisions — the rent percentage during holdover (typically 125–150% of last rent) and whether holdover is month-to-month or converts to a periodic tenancy
Common error: Entering commencement date and expiration date without flagging that rent does not start until a later date, causing early billing errors.
Category 4: Base Rent
- Starting base rent — monthly and annual amounts
- Starting rent per square foot — annual basis
- Rent commencement date (if applicable)
- Full rent schedule — one row per rent period, with start date, end date, monthly amount, and annual amount
- Lease year definition — is the lease year defined from commencement, or does it follow the calendar year?
Common error: Capturing only the starting rent and not the full escalation schedule, causing future billing errors when rents step up.
Category 5: Rent Escalations
- Escalation type — fixed percentage, fixed dollar step-up, CPI, or combination
- Annual escalation rate — the percentage for fixed escalations
- Escalation frequency — annually, every 3 years, at specific dates
- Escalation dates — the exact dates when rent changes
- CPI index — specific BLS series and geographic coverage (for CPI escalations)
- CPI base index date — the date of the base CPI measurement
- CPI cap / floor — minimum and maximum annual CPI adjustment
- Compound vs. flat escalation — clarify in the notes if the lease language is ambiguous
Category 6: Operating Expenses
- Lease structure type — NNN, modified gross, gross, full service
- CAM estimate at commencement — annual amount
- Real estate tax estimate — annual amount
- Insurance estimate — annual amount
- Pro-rata share percentage
- Pro-rata share denominator — how the denominator is defined (total building RSF, occupied RSF, a fixed denominator)
- CAM cap — cumulative or year-over-year cap on tenant's CAM increases; base year for cap
- Management fee cap — maximum allowable management fee as a percentage of gross revenues
- Gross-up provision — the occupancy threshold for grossing up variable expenses
- CAM exclusions — specific items excluded from CAM (capital items, executive salaries, leasing commissions, depreciation)
- Audit rights — tenant's right to audit landlord's operating expense records; notice window and timing after reconciliation delivery
Common error: Failing to note the CAM cap base year, which determines what expenses can be escalated going forward in cap-limited leases.
Category 7: Security Deposit
- Security deposit amount
- Security deposit form — cash, letter of credit, or combination
- Letter of credit details — if applicable: issuing bank, expiration date, draw conditions, renewal obligations
- Burn-down schedule — if the security deposit reduces over time based on conditions
- Return conditions — timeline and conditions for return of deposit at lease expiration
- Landlord's right to apply deposit — circumstances allowing landlord to draw on the deposit
Category 8: Options
- Renewal options — number of options, term length per option, and whether they are exercisable only in sequence
- Renewal option rent — how renewal rent is determined (fixed rate, fair market value, FMV with floor/ceiling)
- Renewal notice deadline — the date by which notice must be given; express as a calendar date, not just "X months before expiration"
- Renewal option conditions — conditions for exercise (e.g., tenant not in default, tenant in occupancy)
- Expansion option — right to lease additional space; trigger conditions, notice requirements, rent determination
- Termination option — right to terminate before expiration; termination date, notice deadline, termination fee calculation
- Right of first offer (ROFO) — right to receive first offer on defined space; trigger, notice period, response window
- Right of first refusal (ROFR) — right to match a third-party offer on defined space; trigger, notice period, response window
- Purchase option — right to purchase the property; exercise conditions, price or price determination methodology
Category 9: Assignment and Subletting
- Assignment rights — whether and under what conditions the tenant may assign the lease
- Subletting rights
- Landlord consent standard — "sole discretion," "reasonable consent," "not to be unreasonably withheld"
- Landlord recapture right — landlord's right to recapture the space if assignment or subletting is requested
- Permitted transfers — assignments that do not require landlord consent (affiliate transfers, corporate restructurings)
- Profit sharing on sublease — whether excess rent received in a sublease is shared with landlord; split percentage
Category 10: Insurance Requirements
- Commercial general liability — required coverage amount (per occurrence and aggregate)
- Property insurance — whether tenant must carry property insurance on its personal property and improvements
- Additional insured — confirmation that landlord is named as additional insured
- Waiver of subrogation — whether tenant's insurer waives subrogation rights against landlord
- Worker's compensation — statutory limits required
- Business interruption — if required
Category 11: Use and Exclusivity
- Permitted use — the specific use or uses permitted under the lease
- Prohibited uses — any restrictions on how the premises may be used
- Exclusive use provision — whether the tenant has exclusivity at the property for certain business types or operations
- Co-tenancy provision — conditions that must be met for the lease to remain in effect at full rent (anchor tenancy, occupancy percentage)

- Landlord work — what construction the landlord will complete before delivery
- Delivery condition — the condition of the premises at delivery (shell, warm shell, as-is, built-out)

Category 14: Governing Law and Administration

This checklist reflects the 126-field schema used by Lextract's extraction pipeline, which covers all 14 categories systematically. Lease abstraction tools that work from a fixed schema ensure that none of these fields are missed — which is the principal advantage over ad-hoc manual abstraction where the reviewer's knowledge and attention determine what gets captured.
