To calculate rentable square footage for a smaller (less than full-floor) tenant, first multiply the usable square footage by the floor common factor, then multiply that result by the building common factor. It also includes any associated common areas and is applied to the Floor Rentable Area to calculate the Rentable Area. Unless otherwise stated, all calculations are based on floor values and measurements. It also defines the calculations required to arrive at BOMA 2017 calculated spaces.

The exception is the BOMA 2010 R/O ratio.One of the goals of Method B is to apply a single, uniform load factor for the entire building to arrive at a Rentable Area for each floor.

In 2017, BOMA released a document entitled "BOMA 2017 for Office Buildings." This occurs by using all shared space in the building to arrive at the load factor. In determining rentable areas, BOMA 1980 employs floor common area only. For example, areas such as occupant storage areas in the basement, a “public colonnade”, and parking are considered to be rentable exclusions. GROSS FLOOR AREA. Net Rentable Area - (Same as Rentable Area). The floor area within the inside perimeter of the exterior walls of the building under … Remember that the usable square footage is the area that can be rented to tenants and the rentable square footage is that area plus common areas. Unless otherwise stated, all calculations are based on floor values and measurements. BOMA Best Practice #20-Should retail occupants in mixed use buildings be charged rent based on Occupant Area or Rentable Area? In 1915, BOMA published its first office standard, Standard Method of Floor Measurement.Throughout the years the standard has been revised to reflect the changing needs of the real estate market and the evolution of office building design. All rights reserved. The floor area of a building, or portion thereof, not provided with surrounding exterior walls shall be the usable area under the horizontal projection of the roof or floor above. METHOD A - Exterior Wall Methodology; METHOD B - Drip Line Methodology In the BOMA area calculation standard, spaces are classified as follows: With BOMA 2017 both rentable exclusions and vertical penetration categories are excluded from rentable area.One of the goals of Method A is to determine a Rentable Area by proportionally allocating shared Service and Amenity Areas to occupants using multiple load factors: one for each floor and one for shared spaces that serve the building. Net rentable area is determined by measuring the overall square footage of a space, floor or building and subtracting all vertical penetrations. The simple definition is that the net rentable area is the area (or square footage) for which rent can be charged. The standard achieves this by defining a “Load Factor B”; in ARCHIBUS terms, this is simply the R/U ratio of the building, not an R/U ratio specific for each floor.The following table illustrates equivalent terminology between BOMA 2010 and ARCHIBUS, and the calculations required to arrive at each term’s value.

The gross leasable area usually incorporates a “core factor” of 15-25 percent of more. Knowing this formula helps companies to evaluate their best deal for office space. Commercial office floor area calculation methods. The BOMA standard included in AutoCAD Architecture# includes the subset of BOMA rules that are described in the following sections. To do this calculation, simply multiply your rentable square feet with your annual base rental rate.

It also defines the calculations required to arrive at BOMA 2017 calculated spaces.System Administration / ARCHIBUS System Administration / ARCHIBUS Administrator - Application Configuration / Configure Application ParametersCopyright © 1984-2019, ARCHIBUS, Inc. All rights reserved.

Commercial office floor area calculation methods. ft. office space that you are looking to lease probably isn’t really 5,000 sq. net rentable area: Actual square-unit of a building that may be leased or rented to tenants, the area upon which the lease or rental payments are computed.

One of two methods may be used in this calculation guided by the dominant market practices of the area. Free rental property calculator estimates IRR, capitalization rate, cash flow, and other financial indicators of a rental or investment property considering tax, insurance, fees, vacancy, and appreciation, among other factors.
