1. No, the standard does not allow any unenclosed areas to be calculated as Building Amenity Area or otherwise. The only unenclosed areas that may be included in the BOMA 2010 Office Standard are External Circulation, Exterior Door Setbacks, certain Building Service Areas and certain areas within an Unprotected Exterior Opening.

2. There is no way to deal with this when using BOMA 2010 because the area is unenclosed. Therefore, some other separate agreement would have to be in force.

3. Generally not. We consider private executive washrooms as part of the occupant area but washrooms that are part of the building core or that would be shared on a multi-tenant floor should be Floor Service and Amenity Area. Mechanical rooms should not be occupant area either unless the mechanical room was built by the occupant to serve their own internal needs. Only a multi-occupant corridor and elevator lobby located on a single occupant floor may be considered Occupant Area.

3B. BOMA tries to avoid a change in the r/u ratio when going from a single occupant floor to a multi-occupant floor, which is why washrooms and mechanical rooms are generally always to be considered Floor Service and Amenity Area.
