BOMA Leasing
Floor Plans & Area Calculations
We deliver BOMA-compliant floor plans and certified area calculations for commercial properties — the industry-standard documentation that landlords, tenants, and brokers rely on to negotiate, execute, and verify leases with confidence.
Accurate Area. Defensible Leases. No Disputes.
BOMA — the Building Owners and Managers Association — sets the measurement standard that the entire commercial real estate industry uses to define and communicate rentable area. When a floor plan and area schedule are calculated to the BOMA standard, every party to a lease is working from the same, defensible number.
Inaccurate or non-standard area calculations are one of the most common sources of lease disputes. Tenants overpay for space they don’t have. Landlords under-declare rentable area and leave income on the table. We eliminate both problems by laser-scanning the property, applying the correct BOMA methodology, and delivering a fully documented area calculation that stands up to scrutiny.

Which BOMA Standard Do You Need?
BOMA publishes separate measurement standards for different building types. Applying the wrong standard — or applying no standard at all — produces an area figure that cannot be meaningfully compared to the market, and that sophisticated tenants and their lawyers will challenge.
We apply the correct BOMA standard for your asset class automatically, and document our methodology in the area report so any reviewer can verify the calculation step by step.

- BOMA 2018 Retail properties & shopping centres
- BOMA 2012 Industrial & warehouse facilities
- BOMA 2010 Mixed-use & multi-unit residential
Every Area Category, Precisely Defined
BOMA methodology categorises every square foot of a building into distinct area types. We calculate, colour-code, and schedule each one on your floor plans.
Usable Area (UA)
The space exclusively occupied by a tenant — the net area within the demising walls of a suite, excluding columns and vertical penetrations.
Common Area (CA)
Shared amenity areas on a floor — lobbies, corridors, restrooms, and service rooms — allocated proportionally across all tenants on that floor.
Rentable Area (RA)
Usable area plus the tenant’s pro-rata share of common areas — the number on which rent is calculated and the figure stated in the lease.
Load Factor (R/U Ratio)
The multiplier applied to usable area to arrive at rentable area — calculated per floor and for the building as a whole, transparently documented in the area schedule.
Who Relies on BOMA Floor Plans
Every party to a commercial lease transaction needs accurate, standardised area documentation — from the landlord setting the asking rate to the tenant verifying what they’re signing.
Building Owners & Landlords
Establish defensible rentable area figures for the entire building before going to market — eliminate tenant challenges and negotiate from a position of documented certainty.

Legal & ArbitrationOur Proven Process
1. Site Scheduling
We confirm the building type, number of floors, current tenancy configuration, and applicable BOMA standard before scheduling the on-site measure.
2. LiDAR Scanning
Every floor is scanned in full — suites, common areas, service rooms, and core elements — capturing the precise geometry required for a BOMA-compliant calculation.
3. BOMA Calculation & Drafting
Our team applies the correct BOMA methodology to the scan data, produces colour-coded floor plans, and prepares a fully documented area schedule with load factors for each floor.
4. QA & Delivery
Floor plans, area schedule, and methodology report are peer-reviewed and delivered as a complete leasing package — AutoCAD DWG, colour PDF, and Excel area report.
