Answer: Areas that are permanently covered but not enclosed
should be inventoried as assignable or nonassignable space depending upon
the space use. Bounding the area with “phantom walls” along the drip line of the “cover” defines the area to be measured and added to the building’s
gross area as well as to the assignable or Nonassignable Area, depending
upon the use of the space. A space use, whether floored or not, that exists
beyond the drip line of the covered area is not reported. Alternately,
the area beneath a permanent cover that extends beyond a floored area is
also not reported.
Answer: By creating “phantom walls,” you would classify this assignable area as Food Facility (630). This area should also be reported as part of the building’s
Answer: It is preferable to treat each addition/wing as
a separate structure, depending upon factors such as the source of
the funds; the separation of each structure’s mechanical, electrical,
or plumbing systems; the age differences of the two joined facilities,
etc. If treated as separate structures, commonly shared walls would
be prorated one-half with each of the respective facilities.
Answer: The area on the uppermost usable floor with a vaulted
ceiling should be included in that floor’s gross area. Since assignable area includes any interior space having 3'0? or more of ceiling height, in your case, the assignable area would be measured from the smallest floor to ceiling distance—the 4’0” kneewall
of the space. Attic space used for administrative offices should be categorized
as Office (310). Attic space containing HVAC equipment should be designated
as nonassignable Utility/Mechanical Space (Y04).
