    Maximum allowable building area requires to use the lot area x FAR which is 3.0 as Eric explained setbacks would be required to get how much of this area you will distribute in a certain number of stories. In this case the question asks for net area reasons why he multiple lot area x 0.75 which is the building efficiency ratio. Hope this help!

    I don't like the 'estimated building efficiency' part of this question.  The 75% would be the LEAST efficient and there's no reason why the FAR couldn't or wouldn't be at 100%.  Efficiency usually refers to energy usage.  It's actually less efficient to build a smaller building with less stories.  I think he meant to say that the client wants to keep the building under the FAR.

    I came up with 22,500sf at FAR 3.0.  This would be a 7 story building with 3,150 sf per flr.  At 75% the building would be 5 stories instead.

    Hope this helps!
