That area determined as rentable using Method A (Exterior Enclosure Method) described in Section A of this Standard or using Method B (Drip Line Method) described in Section B of this Standard.
Because of dissimilarities among buildings, calculations of rentable area may vary. If requested, owners should disclose to prospective tenants the loss factor used for spaces under consideration.
This method measures the tenant's pro rata portion of the entire office floor, excluding elements of the building that penetrate through the floor to areas below. The Rentable Area of a floor is fixed for the life of a building and is not affected by changes in corridor sizes or configuration. This method is therefore recommended for measuring the total income producing area of a building and for use in computing the tenant's pro rata share of a building for purposes of rent escalation. Lenders, architects and appraisers will use Rentable Area in analyzing the economic potential of a building.
In general the Rentable area of a building includes all the areas of a building measured within a predetermined boundary as in BOMA'S Interior Gross Area (IGA) and generally excluding Major Vertical Penetrations. Usable Area multiplied by R/U Ratio.
