Free BOMA Remeasurement Impact Calculator
Model the NOI impact of moving from BOMA 2017 to BOMA 2024. Download free.
BOMA 2024 changes how buildings measure rentable area — and that directly impacts your rent revenue, expense recovery, and NOI. This calculator models the financial impact of remeasurement so you can decide when (and whether) to transition, and quantify the effect on every tenant in your building.

Frequently Asked Questions
What changed from BOMA 2017 to BOMA 2024?
BOMA 2024 introduced updated definitions for outdoor areas, covered galleries, and semi-enclosed spaces. It also refined how vertical penetrations and interstitial spaces are measured. For many office buildings, the net effect is a change in rentable area that can increase or decrease depending on building design and the treatment of previously unmeasured spaces.
How does remeasurement affect NOI?
When rentable area changes, it directly impacts revenue (rent per SF multiplied by new rentable area) and expense recovery (pro-rata shares recalculated on updated denominators). If rentable area increases, landlords may recover more rent and expenses. If it decreases, the opposite occurs. The NOI impact compounds across every tenant and every expense category.
When should a landlord remeasure under BOMA 2024?
The optimal timing depends on lease rollover schedules, capital improvement plans, and market conditions. Many landlords remeasure during major renovations, tenant turnover, or refinancing events when updated measurements can be incorporated into new lease terms. Remeasuring mid-lease typically requires tenant consent unless the lease specifies a remeasurement clause.
How does remeasurement affect existing tenant pro-rata shares?
Existing leases define pro-rata shares based on the rentable area at lease execution. Remeasurement changes the building denominator, which shifts pro-rata shares for all tenants. Most leases lock the tenant's numerator (their suite area) but allow the denominator to change with remeasurement. This means per-tenant expense obligations can shift even without a lease amendment.
What is the typical rentable area change from BOMA 2017 to 2024?
The change varies significantly by building type and design. Office buildings with large lobbies, covered walkways, or outdoor amenity spaces may see increases of 1-5% in rentable area. Buildings with simple floor plates and minimal common areas may see minimal change. The only way to know your specific impact is to have a certified measurer apply the 2024 standard to your building.
