Recapture Rentable Area

Your rentable area is hidden in the standard.

Every BOMA revision redraws what counts as rentable. Update the standard your portfolio is measured to, and new rules free up RSF you already own. See how much across a portfolio your size — below.

Typical gain reflects the 2–5% range documented across industry remeasurement data, with Stevenson Systems field engagements averaging 6% — and up to 8% in some cases. The net effect of BOMA 2024 runs in both directions — new outdoor area becomes billable, previously loaded outdoor space loses its multiplier. It cannot be assumed neutral without a direct calculation.
What the standard captured

Revisions after BOMA 1980

BOMA 1996Revision 1
01
What changed
Introduced the Rentable/Usable framework and the load factor concept as currently applied.
02
Effect on rentable area
Common areas formally allocated to tenants via a proportional share.
03
Example revenue impact
Establishes the baseline load factor most portfolios still reference.
BOMA 2010Revision 2
01
What changed
Added Method B (single load factor) alongside Method A. Revised treatment of mechanical floors and service areas.
02
Effect on rentable area
Uniform load factor across tenants became possible. Cleaner calculation for multi-tenant assets.
03
Example revenue impact
Buildings applying Method B report a single consistent load factor — easier to defend in disposition.
BOMA 2017Revision 3
01
What changed
Rewrote standard in a step-by-step format. Introduced partial treatment of balconies and exterior amenities.
02
Effect on rentable area
Some outdoor areas became rentable for the first time — with load factors applied.
03
Example revenue impact
Buildings with terraces or balconies typically saw 1–3% RSF increases at remeasurement.
BOMA 2024Revision 4
01
What changed
Reclassified unenclosed tenant areas, rooftop equipment, tenant storage, and single-tenant shafts. Load factor removed from Non-Allocated Tenant Areas. Method B simplified.
02
Effect on rentable area
Rentable area expanded. Load factor math shifted. Net effect runs in both directions — billable space added, but previously loaded outdoor space loses its multiplier.
03
Example revenue impact
Typical remeasurement uncovers 2–5% additional RSF. Stevenson field average: 6%, with upside to 8% on portfolios with significant tenant-controlled amenities.

The square footage was always there.
The standard is what changed.

Rentable area isn't fixed — it's defined by the BOMA edition your building is measured to. Each revision has reclassified more of the building as rentable: shared amenities, circulation, mechanical and service areas.

If your portfolio still sits on an older edition, that reclassified area is RSF you already own but aren't billing. Updating the standard is what frees it — no construction, no new space.

That's the recapture, and it's hidden in the standard.

Pick your current standard above to see the revisions you've missed and the RSF in play across a portfolio your size — three minutes, no login.

Schedule a Measurement Review

The calculator shows the gap.
A measurement review
recaptures it.

The estimate above is the start. Our team measures your buildings to the current BOMA standard and turns that hidden square footage into verified, billable RSF — backed by the people who co-authored the standard.

  • Verified RSF per floor and suite
    Independent, BOMA-compliant measurement of every floor — the number you can put on a lease.
  • Variance against your rent roll
    A side-by-side of your current figures and what a current measurement finds, with every discrepancy documented.
  • Findings you can act on
    Recommendations for lease language and renewal strategy so the recaptured area actually reaches revenue.
  • From the standard's co-authors
    Delivered by the team involved in 18 editions of the BOMA standard your leases are built on.
