Single Story Building with One Occupant

Ryan McDonald

I am evaluating a single story building in which all spaces, lobby, offices, restrooms, corridors, etc. are occupied by one tenant. According to the 2010 BOMA Standard are all such spaces within the IGA boundary classified as Occupant Area or would you classify service spaces and amenity spaces separately?

Additionally, given that it’s a one-story building would these space be classified as Building amenity/service areas or Floor amenity/service areas?

Thank you,

Hi Ryan,

Classify service and amenity areas separately. Note that the total rentable area will be exactly the same; the single tenant will just be pro-rated for 100% of the service and amenity areas.

The Standard does not distinguish between single-story and multi-story buildings. I think a mix of building and floor amenity/service areas is appropriate. For example, building function rooms like mechanical rooms should be Building Service Area, whereas circulation corridors or other core elements may qualify as Floor Service Area. There is rarely a good reason to call anything Floor Amenity Area (in fact it nearly didn't make it into the Standard at all!).
