The 24 Fields Every Commercial Lease Abstract Needs (and the 6 People Forget)
By the LeaseCodex team · Updated July 2026 · ~7 min read
Ask five lease administrators what belongs in an abstract and you'll get five overlapping-but-different lists. This is ours — the 24 fields we extract on every lease, organized the way careful teams actually use them, with honest notes on which ones cause the most pain when they're missing.
Want it as a working spreadsheet? The free template has all 24 fields with source-page and verification columns built in.
Parties & property (7 fields)
| Field | What to capture |
|---|
| Document name | The instrument's own title, so the abstract traces to the right document |
| Landlord | Exact legal entity — not the management company collecting rent |
| Tenant | Exact legal entity — matters enormously at enforcement/assignment time |
| Guarantor | Whether a guaranty exists and who signed it |
| Property address | Street, city, state of the premises |
| Suite / unit | The specific demised space |
| Rentable square feet | The number every $/SF calculation depends on |
Term & options (5 fields)
| Field | What to capture |
|---|
| Lease start date | The commencement date — or the rule that defines it if it's event-based |
| Lease end date | The anchor for every deadline you'll ever track on this lease |
| Initial term | As stated (years/months) — sanity-checks the dates |
| Renewal options | Count, length, and rent basis of each option |
| Renewal notice deadline | The exercise window as actual calendar dates — see below |
Rent & escalations (3 fields)
| Field | What to capture |
|---|
| Base rent schedule | Amounts and periods — every step, not just year one |
| Escalation terms | The mechanism: fixed %, CPI, stepped, FMV reset (try our escalation calculator) |
| Percentage rent | Breakpoint and reporting duties, if retail |
Expenses & deposits (3 fields)
| Field | What to capture |
|---|
| CAM / operating expenses | Pro-rata share, base year vs NNN, caps and exclusions, reconciliation timing |
| Security deposit | Amount, form (cash vs letter of credit), burn-down provisions |
| Utilities | Who pays, and how it's metered or billed |
Use & responsibilities (3 fields)
| Field | What to capture |
|---|
| Permitted use | What the tenant may do in the space |
| Maintenance responsibilities | The repair/replace split, with dollar thresholds |
| Insurance requirements | Coverage types, limits, additional-insured requirements |
Rights & restrictions (3 fields)
| Field | What to capture |
|---|
| Assignment / subletting | Consent standard, recapture rights, permitted transfers |
| Termination rights | Kick-outs, relocation rights, early termination — for either party |
| Exclusive use / co-tenancy | What the landlord promised this tenant no one else may do |
The 6 fields people forget — and what forgetting costs
- The renewal notice deadline (not just the option). Teams record "one 5-year option" and skip the exercise window. The option is worthless if notice isn't given in time — compute the actual date (our deadline calculator does it and exports a calendar reminder).
- Escalation mechanics. "Rent goes up" isn't a field. Fixed 3% compounds very differently from CPI-linked with a floor; budgeting off the wrong mechanism misprices the whole lease.
- CAM caps and their exclusions. A "5% cap" that excludes taxes, insurance, and utilities caps almost nothing. The exclusions are the field.
- Landlord relocation/termination rights. Hidden in the back third of the lease, remembered only when the landlord invokes them.
- The maintenance dollar thresholds. "Tenant maintains HVAC" often means "up to $X per occurrence" — the X is what settles disputes.
- Which document controls. After two amendments, an abstract that doesn't say where each value came from can't be trusted or updated.
The meta-field: source pages. Every value in an abstract should carry the page of the lease it came from. It's what turns "a spreadsheet somebody typed" into a document your team — and your attorney — can verify in seconds. It's also why
LeaseCodex abstracts cite a source page for all 24 fields.
