The improvement allowance calculated on a per-square-foot basis.
The per-RSF rate enables apples-to-apples comparison between competing lease proposals with different suite sizes. A $60/RSF allowance on a 5,000 RSF space ($300,000 total) is objectively more generous than a $50/RSF allowance on a 7,000 RSF space ($350,000 total) because the per-unit construction cost is the same regardless of space size. This metric is the standard benchmark used by tenant representatives.
In the "Tenant Improvements" or "Work Letter" section. May be stated explicitly or must be calculated by dividing the total TI amount by the tenant's RSF.
Lextract uses vision AI to read your lease PDF natively (scanned or digital), then multi-pass AI validation identifies and extracts the tia per rsf. The AI searches for all pages of the document, then assigns a confidence score based on document quality and extraction certainty. Fields with lower confidence are flagged for human review.
Always compare on a per-RSF basis and factor in the lease term. A $60/RSF allowance on a 10-year lease is effectively $6/RSF/year, while $40/RSF on a 5-year lease is $8/RSF/year. The shorter-term lease actually provides more annualized construction value.
It depends on the lease. Most quotes reference RSF for consistency with the rent calculation, but some landlords quote per USF which yields a higher per-square-foot number for the same total amount. Always confirm the measurement basis when comparing proposals.
