The number of elevated loading bays designed to align with semi-truck beds.

Dock-high doors are essential for efficient freight loading and unloading. Each door handles approximately 4-6 truck turns per day depending on cargo type. Insufficient doors create bottlenecks, with trucks queuing for available docks, increasing labor costs and carrier detention charges. A warehouse with 10 dock doors can process 40-60 trucks daily, while one with only 4 doors is limited to 16-24 turns -- a critical constraint for high-volume distribution operations.
Found in the "Premises" or "Building Specifications" section of industrial leases. Often included in a building data sheet or site plan exhibit. The door dimensions (typically 8'x10' or 9'x10'), dock levelers, and dock seal specifications may also be noted.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the dock-high doors 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.
Utilities Payment
How utilities are billed to the tenant.
Janitorial Services
Identifies whether the landlord or tenant is responsible for cleaning the premises.
Clear Height (ft)
The usable vertical clearance inside an industrial warehouse facility.
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.
A common rule of thumb is one dock-high door per 5,000-10,000 RSF of warehouse space. Cross-dock facilities need more doors (one per 2,500-5,000 RSF). The exact requirement depends on throughput volume, dwell time, and whether the operation runs single or multiple shifts.
Dock-high doors are elevated 48-52 inches to align with standard semi-truck trailer beds, allowing forklifts to drive directly into the trailer. Grade-level doors (drive-in doors) are at ground level, suitable for van deliveries, vehicle access, or loading smaller vehicles.
