How do I add Job_GreetedPlayerVisitingNPC on "Lot Entry"

I'm trying to figure out how to add the Job_GreetedPlayerVisitingNPC to my sim when they spawn on a residential lot, so the lot is accessible without knocking on the door.

- wich loot action triggers when entering a lot?
- is the SituationJob the right type to add or is it the Situation itself I need to add?

Thanks for any help!
