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.
Identifies whether the landlord or tenant is responsible for cleaning the premises.

Janitorial responsibility determines both who controls cleaning quality and who bears the cost. Landlord-provided janitorial is typically included in operating expenses and provides standardized service. Tenant-provided janitorial gives more control but adds $0.50-$2.00/RSF annually to occupancy costs. In medical, food service, and laboratory environments, specialized cleaning requirements often necessitate tenant-managed janitorial regardless of the lease default.
Found in the "Services" or "Landlord Services" section. In office leases, janitorial is typically listed among the landlord-provided services. In industrial and retail leases, it is usually the tenant's responsibility and is stated in the maintenance obligations section.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the janitorial services 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.

In multi-tenant office buildings, the landlord typically provides janitorial service for the premises and common areas, with the cost included in operating expenses. In industrial, retail, and single-tenant properties, janitorial is almost always the tenant's responsibility.
Standard landlord-provided janitorial typically includes nightly vacuuming, trash removal, restroom cleaning and restocking, and periodic window cleaning. It usually does not include day porter service, carpet shampooing, or specialized cleaning for kitchens, server rooms, or medical facilities.
