AI Lease Abstraction Accuracy: Benchmarks and What to Expect
What accuracy can you realistically expect from AI lease abstraction tools? We break down field-level accuracy rates, where AI excels, where it struggles, and how to validate output.
The total maximum liability coverage required for the policy period.
Also known as: General Aggregate
By Angel Campa, Founder · Updated March 2026
The aggregate limit caps total insurance payouts across all claims in a policy year. Once exhausted, the tenant and landlord are personally exposed. Standard leases require $2 million aggregate, but businesses with frequent customer interactions may need higher limits. If the lease requires an aggregate significantly above the tenant's current policy, the premium increase can add $2,000-$5,000 to annual occupancy costs.
Listed alongside the per-occurrence limit in the "Insurance" section. Standard formatting shows both limits together (e.g., "$1,000,000 per occurrence / $2,000,000 general aggregate").
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the cgl aggregate limit from your lease PDF. The AI searches for the field name and common aliases like "General Aggregate" across all pages of the document, then assigns a confidence score based on OCR quality and extraction certainty. Fields with lower confidence are flagged for human review.
CGL Occurrence Limit
The minimum liability coverage required for a single incident.
Property Insurer
Specifies whether the landlord or tenant insures the physical building/improvements.
Waiver of Subrogation
A mutual agreement preventing insurers from suing the other party to recoup losses.
Additional Insured
Requirement for the tenant to add the landlord to their liability policy.
Indemnification Scope
The extent to which the tenant holds the landlord harmless from liability claims.
$2,000,000 is the standard general aggregate limit in most commercial leases. This is typically twice the per-occurrence limit. High-risk tenants or large portfolios may need $3-5 million or more, often achieved through umbrella policies.
If total claims exceed the aggregate limit during the policy period, the tenant has no remaining CGL coverage. An umbrella policy provides additional layers of protection. Some leases require tenants to carry umbrella coverage precisely for this reason.
