A building with mechanical rooms in the basement and fully enclosed mechanical spaces at the penthouse level :
A- If the building is single tenant are these space rentable?
B- Are they considered "building service areas"?
C- What happens if in future the building becomes multi-tenant?
D- Does the same apply to mechanical spaces on the occupied floors?
A-Whether it is a single occupant or multi-occupant building these are included as rentable
B-Yes
C-It will not make a difference to the rentable area of the building under BOMA 2010, but the addition of multi-occupnat corridor's will require an update to the area analysis.
D-Mechanical spaces on occupied floors are usually Floor Service and Amenity Area but could also be Building Service Area (depending on its purpose). This allocation however generally does not change as a result of a building becoming multi-occupant.
