This is happening to me too, but I am on a PC. My Sim landlord lives on the same lot as his tenants. There is currently a maintenance event taking place in a tenant's unit, but my landlord cannot access. I have tried visiting the unit by clicking on in and choosing to visit there. I have also traveled to the unit from within the residential rentals owned businesses menu. I tried moving my landlord off the lot and then visiting from his new home lot. Each time I was unable to knock on the door. I was given the option to "Switch to control this household" or "Lock door for." I can see inside the house and select objects to be repaired, but as my Sim approaches the front gate, he will wave and indicate that he cannot access the object.
