For Sarpong/Loden, the business doors give me the option to switch control to household in white, and the residential doors show switch control but greyed out. Same goes for any other doors on the other floors in the Sarpong household's case (photos below). Whereas with Koopman, the business door has switch control, knock, and the For Rent options of eavesdropping and breaking in, and the residential door has just switch control in white. I can only knock on the business door for them as I'm assuming that is what is set as the front door.
I've made a fresh save and it's working completely fine, just as the Koopman lot does in the save I'm having the issue with. I'm able to access the residential parts of all 3 businesses with no problems in this new save. So I'm guessing it'll be an issue with my specific save? Like I said, this is a new pack for me and I've literally only played in one save so far since I got it (excluding the test save I just made), so I don't what could have caused this, as it happened the very first time I went to visit someone else's house.

Did you visit as a customer before that or not at all ?
Not for the Sarpong household, no, that was my first visit. Brief timeline of events:
I'm not having any problems when I choose to visit as a customer at any of the three lots, it's when I try to visit the Sarpong and Loden households as a guest. The game acts as if I am visiting as a customer, and I'm unable to knock on the door or access their residential spaces.
