I am building this retaining wall that ends with steps. The steps will be on one side against the foundation of the house.

enter image description here

My question is should I use expansion joints between the step units (SRW concrete units) and the foundation or it'd be over-engineering?

The 2 options I found are:

If yes to the above question, which option is better?
Any other suggestion would be very much appreciated.

Both of your expansion joints are OK to use. And yes its not over engineering, Better to deal with it now then pay for it in the longrun.

depends on where you are. in cold climates like here in Ontario, expansion joints are gospel. when the temperature gets down to -40 c, an assembly like that without an EJ can blow a hole right through a poured wall. if its cold like it is here, pull it apart and put the EJ in before it freezes up for the winter.
