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 usable vertical clearance inside an industrial warehouse facility.
Also known as: Clear Headway, Ceiling Height
By Angel Campa, Founder · Updated March 2026
Clear height determines the maximum racking height and storage density in a warehouse. Each additional foot of clear height can increase storage capacity by 8-12% through taller pallet racks. Modern logistics require 32-40 foot clear heights for efficient operations. A warehouse with only 24 feet of clear height may need 30% more floor area to store the same volume, dramatically increasing rent costs for the tenant.
Found in the "Premises" or "Building Specifications" section of industrial leases. May be stated as "clear height," "eave height," or "minimum ceiling clearance." Measured from the finished floor to the lowest obstruction (typically bottom of joists or trusses).
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the clear height (ft) from your lease PDF. The AI searches for the field name and common aliases like "Clear Headway", "Ceiling Height" 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.
Utilities Payment
How utilities are billed to the tenant.
Janitorial Services
Identifies whether the landlord or tenant is responsible for cleaning the premises.
Dock-High Doors
The number of elevated loading bays designed to align with semi-truck beds.
Drive-In Doors
The number of grade-level doors allowing vehicle entry into the warehouse.
Power Capacity
The quantitative electrical capability delivered to the premises.
Modern Class A warehouse construction features 32-40 foot clear heights. Older buildings may have 20-28 feet. For e-commerce fulfillment, 36+ feet is preferred. Cold storage facilities typically need 30-35 feet. Clear heights below 24 feet limit racking options and reduce storage efficiency.
Higher clear heights allow more cubic storage in the same footprint, effectively reducing the cost per unit stored. A 36-foot warehouse at $8/RSF can store 50% more inventory than a 24-foot warehouse at $6/RSF, making the taller building cheaper on a per-pallet basis despite the higher rent.
