Dave, the NMRA track gauge has clearances on it. Here's a link to the NMRA page that explains everything. http://www.nmra.org/standards/sandrp/gauge.html
Alternatively, you can just use some rolling stock to determine the clearance, put the building just a tad away, maybe 3/32" or so. Also, I have found that locos with sun shades over the windows are sometimes wider than boxcars, so allow for that if engines will be running next to the buildings. Also, more clearance is required for curves.
I am interested in hearing other people's responses too.
