I’m not sure I understand you correctly. Chef is an npc selected for this vacation. I cannot select him and close the door for everyone but chef. I don’t have such an action on the door. And the sims I can open the door to are those who only live in my household.
I see. Thats inconvenient.
Just to be sure, this is what I mean to lock the doors:
But if you can find that NPC in the manage households list (on the world selection and region screens, upper right) you could enter that household, visit the lot and then try to lock the doors. He is assigned to the lot so he should be able to interact this way with the doors. Just set the household to inactive again after you are done.
