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.

Reserved spaces guarantee convenient, accessible parking for executives, key employees, or customer-facing staff. They eliminate the morning competition for spots and project professionalism for client visits. In urban markets, reserved garage spaces can cost $200-$400/month each, adding $2,400-$4,800/year per space to occupancy costs. The number and location of reserved spaces should be documented during abstraction for accurate budgeting.
In the "Parking" section or a parking exhibit/addendum. Reserved spaces are often shown on a parking plan with specific stall numbers or designated areas. Monthly costs for reserved spaces are stated alongside the allocation.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the reserved spaces from your lease PDF. The AI searches for the field name and common aliases like "Executive Parking" 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.
Parking Ratio
The number of spaces allocated per 1,000 square feet of leased space.
Unreserved Spaces
The raw number of non-specific parking spaces granted to the tenant.
Monthly Parking Cost
The fee levied per space for utilizing the parking facilities.
Trailer Parking
The number of oversized spaces dedicated to industrial semi-truck trailers.
Costs vary dramatically by market. Suburban surface lots may include reserved spaces at no charge. Urban garages typically charge $150-$400/month per reserved space. Premium CBD locations can exceed $500/month. The cost is usually stated separately from base rent and may escalate annually.
The lease should specify whether reserved spaces are in fixed locations or subject to relocation by the landlord. Tenants should negotiate for fixed locations (or locations within a defined area) to prevent the landlord from moving reserved spaces to less convenient areas.
