1996 Method A vs. 2010 Method B

Brandon Wenzel: RIM Architects; March 5, 2014

Hello,

I am contacting you regarding a couple of questions we have concerning the BOMA 1996/2010 Office Building Standards and Rentable Calculations. We have a project in which we are determining the gross measurable area and floor rentable area, using the 1996 Method A Standard. My question(s) are the following:

1. For calculating rentable floor area, is there a difference between Method A and Method B for office rentable area?
2. Does the City of San Francisco have a preference on which methodology is used for leasing?
3. Is there a change in the 2010 Office code (Method B) that eliminates common space, restrooms, lobbies, etc. from being included in the overall leasable floor area?

At your convenience, please let me know if can provide us with any correspondence. If you need additional information, please feel free to contact me at any time. Thank you.

Brandon,

1. Yes there are significant differences between calculating Rentable Area according to Method A and Method B. You will need to read the Standard thoroughly to fully understand these differences.

2. I'm really not sure

3. Method B may abstract some common circulation corridors on some floors due to the required implementation of Base Building Circulation (under Method B only). Otherwise there is not any wholesale removal of otherwise traditional common areas.
