At last count-at least at the point in time of the last audited statement-the Pittsburgh Public School District had 71 buildings totaling 7,343k square feet.  That was down from 100 buildings and 9,527k square feet in 2000.  The building count is expected to decrease in the 2012-13 school year is another realignment plan is approved.  All told, five buildings will be shuttered completely after certain schools are closed and programs and operations move to buildings in a new arrangement.

The majority-over 90% in fact-of the District's square footage is related to elementary, middle, special and secondary education.  In 2000, the District had 4 buildings with 287k of square feet used for administrative and financial support (2), operation and maintenance of plant (1), and food service (1).  The combined 287k of those buildings represented 3% of all square footage.  By 2009 the District had added another building counted as administrative and financial support (with 261k of square feet) and the resulting square footage of "back office" space rose to 548k.  With total square footage in the District standing at 7,343k, the District's share of square footage for administration, maintenance, and food rose to 7%. 

We have written a lot about the headcount related to "teachers" and "non-teachers" in the District and the ratio of those classifications to enrollment.  In short, the relative size of non-teachers has risen tremendously while the teacher ratio has remained flat.  It is no surprise that square footage has exhibited a similar trend and that, in the latest round of cuts, no administrative space is disappearing.
