Doors should be locked, home owners should be aggressive, and danger should be associated with every uninvited entry a party makes.
This. I always hated in BG1 that you could enter 99% of the houses uninvited and there would be no consequences, no guards, no one told you to get the hell out. It's like:''Hi! I'm just exploring to see if there's anything to loot, don't mind me :)''
I adored (and
still adore) that decision; it makes the world feels fantastic.
People want to enter every house in BG? Fine, no problem. But at least bring up some reactivity/consequences. Maybe some residents will try to fight you, maybe some will flee, maybe some will call the guards, maybe some will HAVE guards, maybe some will panic and give you their valuables,....THAT would feel fantastic and immersive.
