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 right to place the tenant's name on a shared roadside structure.

Monument signs at the property entrance provide visibility from the road, which is critical for tenants who depend on drive-by traffic. In multi-tenant properties, monument sign position (top panel vs. bottom panel) affects visibility and perceived prestige. Top monument sign rights are often reserved for the largest tenant and have significant brand value. For a restaurant or retail business, monument signage can directly impact revenue.
Found in the "Signage" section or a signage exhibit. Look for the tenant's position on the monument (panel number or location), sign dimensions, and whether the landlord or tenant pays for the panel and lighting.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the monument signage from your lease PDF. The AI searches for 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.
Permitted Use
The specific, legally allowed business activities the tenant can conduct.
Prohibited Uses
Specific activities explicitly banned within the leased premises.
Fascia Signage
The right to affix branding directly onto the exterior wall of the building.
Signage Maintenance
Determines if the landlord or tenant is financially responsible for sign upkeep.
A monument sign is a freestanding sign structure at the property entrance, typically at roadside level. It lists the names of building tenants and is visible to passing vehicle traffic. Position on the monument (top, middle, or bottom) affects visibility. Multi-tenant monuments may list 4-8 tenants.
This depends on the lease language. Some leases tie signage rights to the named tenant and prohibit transfer. Others allow the subtenant to display their name with landlord consent. If subleasing is possible, the assignability of signage rights should be confirmed during abstraction.
