Built new ICF home but missed that designers and me of course did not contemplate need of a footing to support 36″ steps up to covered verranda. Ground is clay and frost line is 4ft in northern Ontario.
My plan:
-excavate to frost line
-build regular footing for 8″ cinder blocks
-lay block in L shape so both edges abut existing poured ICF foundation
-backfill within excavation and without, and finally
build wood steps with stringer resting on cinder blocks
Does this sound ok and am I missing anything?
Thanks for any help.

Couple of thoughts.
you could mount the stars on some properly installed support posts, or even just concrete piers.
What you plan seems like it will be fine. I would want to think about drainage, and make sure water has a good place to leave.
If your poured foundation has a perimeter footer drain, make sure to tie into it with one around your new foundation wall.
I don't know Canadian code, but here you also need a landing that extends at least 3 feet past the bottom tread nosing.
