What constitutes a mixed use property

Would you consider a 15 story office building with ground floor retail a candidate for the mixed use standard?

Hi Steve,

The BOMA Office standard states:

Generally, a building whose occupancy comprises 50% or more of a particular use (e.g. Office, Industrial, Retail, or Multi-Unit Residential), should use the corresponding single-use standard. Therefore, a Building whose primary use is office with ancillary retail, parking, and storage should use this Office Standard.

It is preferable to apply a BOMA single-use standard whenever possible, however the BOMA Mixed-Use Standard is appropriate for buildings that do not have an easily identifiable “primary use," or where the provisions of a governing document (such as a lease, cost sharing or easement agreement, condominium declaration, etc.) constitute an overriding direction with respect to floor measurement.
