Max allowable foundation settlement!
Max allowable foundation settlement!
(OP)
What is the maximum allowable foundation settlement (total settlement and differential) for a building with (3) wood floors, (1) concrete transfer slab, and (2) garage floors below? Is there any literature on this? Does ACI talk about the maximum allowable foundation settlement in a building design? I would appreciate your help.

Sandy soils 50 mm
Clayey Soils 75 mm
Since 2005 the current standing code CTE (Código Técnico dela Edificación, that has undergone already two main revisions) has sections on this, obviously in the intent defined by Bagman.
Download the
DB-SE C: Cimientos
from the site

And see sections 2.4.3, 4.4 and Appendix F.1.2

Total settlement (the whole building settling the same amount) will generally affect only site drainage and building access.
Differential settlement can cause cracking, buckling, misalignment of equipment, tilting, pipe ruptures, tripping hazards, etc.
