Wow, you guys got such great scores.
I am probably a bit paranoid here. Can I drag drinks and food that made by sims to trash can or to sell? Does that count as changing the lot, as once they are made they are placed in the lot? At the same time, dragging paintings to sim inventory is allowed but I just want to be extra sure.
Can I sell furniture made by sims and stored in the house inventory? Again, does it count as changing the lot?
Cooking food, doing the dishes, moving trash to a trash can is not changing a lot.
If you make a paiting and move it to your sims inventory its is also not changing the lot.
And things you created that are placed in the family inventory are also not changing the lot.
Adding new furnitures that is not part of the things we have stated you can buy would be adding to the lot. Same goes for skill things you create. So you cannot hang up a painting or place a tub you made with handiness.
(Food plates are the exception because they are not permanent, when you leave the house the household would clean that up.)
