There are some limited guidelines in UBC Section 1629.1 which indicates you can use Allowable Stress Design along with the load combinations of UBC Section 1612.3 for evaluating sliding and overturning.

For stability checks such as sliding and overturning due to earthquake forces, what is the proper factor of safety? The UBC 97 has some information about wind forces with regard to this, but I have not found anything for earthquake. Would it be safe to say that FS=1.5 should be used, using working stress design level forces (E/1.4)?
Arguably, a FS of 1.0 could be used since the code does not state otherwise (EQ again)
Seems like this information should be in the code.
