Space Accounting

Every square foot is a financial asset.

Space accounting treats building measurement as a financial discipline. SSI accounts for every square foot with the same rigor your finance team applies to revenue, because in commercial real estate, square footage is revenue.

The Discipline

What is Space Accounting?

Most firms measure buildings. SSI accounts for them. The distinction matters. Traditional measurement produces a floor plan and a number. Space accounting produces a financial framework that connects every square foot to your lease revenue.

Peter Stevenson co-authored the BOMA measurement standards that the industry relies on. We built space accounting on that foundation, adding 40 years of practice to create a discipline that treats your building's area the way your accountant treats your books: with precision, consistency, and a clear line to the bottom line.

Our clients consistently uncover 6% additional rentable area in Class A properties. Revenue already sitting in your buildings, waiting to be structured and captured.

Process

How it works

Four stages from strategy to ongoing management. Each builds on the last to create a complete financial picture of your portfolio.

Strategy Consultation

We learn your portfolio goals, lease structures, and revenue targets before we set foot in a building.

02

Field Measurement

Our team measures on-site using laser scanning and BOMA methodology refined over 40 years. Every room and corridor verified.

03

Financial Structuring

Measurement data organized into a financial framework: RSF calculations, load factor analysis, and revenue impact modeling.

Ongoing Management

Your data flows into TruSpace for live portfolio visibility. Numbers stay current and audit-ready through every lease event.
