The number of spaces allocated per 1,000 square feet of leased space.

Inadequate parking directly impacts employee retention and customer traffic. A medical office needs 5-6 spaces per 1,000 RSF to accommodate patients, while a standard office needs 3-4. If the lease provides only 2 spaces per 1,000 RSF, the tenant faces a permanent operational constraint. In dense urban areas, parking costs can add $150-$300 per space per month to occupancy costs, making the ratio a significant financial factor.
Found in the "Parking" section or "Common Areas" provisions. May be stated as a ratio (e.g., "4 spaces per 1,000 RSF") or as a total number of spaces. Some leases reference the parking in an exhibit or site plan.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the parking ratio 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.
Unreserved Spaces
The raw number of non-specific parking spaces granted to the tenant.
Reserved Spaces
The number of explicitly designated, exclusive parking stalls for 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.
Standard office parking ratios range from 3 to 5 spaces per 1,000 RSF. Suburban offices typically provide 4-5 spaces, while urban buildings may offer only 1-2 with public transit alternatives. Medical offices need 5-6 spaces, and retail requires 4-5 spaces per 1,000 RSF.
It depends on the lease language. Some leases guarantee a minimum ratio, while others provide parking on a "non-exclusive, first-come-first-served" basis. Tenants should negotiate a guaranteed minimum to prevent the landlord from reducing parking during the term.
