Know exactly what you own.
Lease revenue depends on accurate rentable square footage. If your RSF was inherited from a prior owner, estimated from old drawings, or never independently verified, you're making financial decisions on unconfirmed data. SSI measures what your buildings actually contain.
RSF drives every lease dollar.
Rentable square footage is the multiplier behind your rent roll. When that number is wrong, every lease in the building carries the error forward. Tenants overpay or underpay, load factors drift from reality, and revenue projections lose their footing.
Most RSF figures in the market were set years ago and never revisited. Buildings change. Without independent verification, you're relying on numbers that may no longer reflect the physical building.

Figures are illustrative estimates based on the inputs and assumptions you provide — not a valuation, appraisal, or guarantee of results. Actual rentable area and revenue impact can only be confirmed through an independent, BOMA-compliant measurement.
How it works.
Four steps from document review to verified reporting — each measurement independent, BOMA-compliant, and built for your lease administration.
Pre-Measurement Review
We review your existing floor plans, lease abstracts, and current rentable square footage figures to identify where discrepancies are most likely hiding.
Field Measurement
Our team measures every floor on-site using laser scanning and BOMA methodology refined over 40 years. Every room, corridor, and common area is captured.
BOMA Classification
Each space is classified according to the standard our founder co-authored: dominant portion, major vertical penetrations, building common areas, floor common areas.
Verified Reporting
You receive a verified RSF report with floor-by-floor breakdowns, variance analysis against prior figures, and direct integration into TruSpace.

What you receive.
Every engagement ends with documentation your lease administration, lenders, and auditors can rely on.
Verified RSF Report
Independent, BOMA-compliant rentable area calculations for every floor. Structured for lease administration and audit readiness.
Floor-by-Floor Breakdown
Detailed area calculations by floor showing usable, rentable, and common area allocations with load factor analysis.
Variance Analysis
Side-by-side comparison of prior RSF figures against verified measurements. Every discrepancy identified and documented.
TruSpace Integration
All verified data loaded into TruSpace for interactive floor plans, stacking plans, and ongoing portfolio management.
Confident numbers start with independent verification.
