BOMA (Building Owners & Managers Association) standards are commonly used in North America. They define areas such as Rentable Area and Usable Area and set rules for how shared spaces (e.g., corridors, lobbies) are apportioned to tenancies.
- Where it differs: PCA (Property Council of Australia) sets NLA/GLA/GLAR rules for Australian leases and valuations. BOMA uses different terminology and boundary rules (e.g., how to treat common areas, wall thickness, and projections), so figures from BOMA and PCA are not interchangeable.
- When to use: If your portfolio or lease documents are aligned to Australian practice, use PCA. If you’re reporting to North American stakeholders or BOMA-based leases, request BOMA. We can produce either—and map one to the other when needed.
