BOMA Measurement Standards Deep Dives
BOMA measurement standards determine how rentable area is calculated — the foundation for both base rent and CAM pro-rata share allocations. These guides cover the 2024 standard updates, worked examples, common errors, and financial impact analysis for each measurement topic.
All BOMA Topics
How the two BOMA measurement methods differ in allocating shared floor areas to tenants, and when each method produces a higher or lower rentable area for a given suite.
Understanding areas within a tenant's demised space that are excluded from usable area calculations under BOMA 2024, including structural columns, shaft enclosures, and building system penetrations.
How BOMA 2024 introduces formal classification of outdoor amenity areas such as rooftop terraces, balconies, and covered patios, and their impact on rentable area calculations.
How BOMA standards classify storage areas in commercial buildings, including in-suite storage, building storage rooms, and below-grade storage, and their treatment in rentable area calculations.
BOMA measurement methodology for floors occupied by a single tenant, including treatment of floor common areas, corridors, and restrooms that become part of the tenant's usable area.
BOMA measurement rules for floors with multiple tenants, including floor common area identification, allocation methods, and the relationship between usable and rentable area.
Defining and measuring major vertical penetrations — elevator shafts, stairwells, mechanical shafts, and other floor openings — and their impact on usable and rentable area calculations.
Understanding the common area factor — the ratio between rentable and usable area — how it is calculated at both the floor and building levels, and its impact on tenant costs.
A detailed walkthrough of how to calculate the load factor (also called the add-on factor or R/U ratio) for a commercial building, from gross area through usable to rentable.
The fundamental distinction between usable and rentable area under BOMA standards — what each term means, how they relate to each other, and why the difference matters for rent and CAM calculations.
A practical guide for property owners and managers transitioning from BOMA 2017 to the 2024 standard, including timeline considerations, lease implications, and implementation steps.
How building lobby areas are classified and allocated under BOMA standards, including ground-floor lobbies, elevator lobbies on upper floors, and the distinction between building common area and tenant-accessible amenity space.
