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.
Determines if the landlord or tenant is financially responsible for sign upkeep.
By Angel Campa, Founder · Updated March 2026
Sign maintenance includes cleaning, bulb/LED replacement, electrical repairs, and structural upkeep. A large illuminated monument sign can cost $500-$2,000 per year in maintenance. If the lease assigns maintenance to the tenant but the tenant neglects it, the landlord may perform the work and charge back the cost at premium rates. Clear assignment of maintenance responsibility prevents disputes and ensures consistent brand presentation.
Found in the "Signage" section or rules and regulations exhibit. May specify that the landlord maintains monument signs (with costs passed through as CAM) while the tenant maintains their own fascia signage. Look for repair timelines and consequences for neglected maintenance.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the signage maintenance 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.
Monument Signage
The right to place the tenant's name on a shared roadside structure.
The landlord usually maintains the overall monument structure, with costs included in CAM charges. Individual tenant panels may be the tenant's responsibility. Fascia signage on the building exterior is almost always the tenant's maintenance responsibility.
Most leases allow the landlord to perform maintenance after written notice and a cure period (typically 15-30 days). If the tenant fails to act, the landlord can repair the sign and charge the cost to the tenant, often at a markup. Persistent neglect may constitute a lease default.
