Personally, I’m not happy with the way some lots have locked traits. Why is the one with the cute balcony locked as “Needs TLC”? What if I want to tell the story that a Sim renovated it and now it’s their little dream home?
Using MC Command Center, you can delete all those items and they will stay gone. Please note that deleting them means they are gone FOREVER. So be sure to save the apartment first in case you want to get them back (you can replace it with the original version). You can save the apartment intact using my post here.
So how do you do it?
First off, go and download MC Command Center. You only need the main part of that mod. Then using the computer on your lot, make sure that Debug Cheats Enabled is set to true (default is false).
Remember that once removed, they cannot be replaced. So be sure to save a copy of the apartment to your gallery in case you ever want them back.
You have to be in live mode and then shift+click on each mouse hole, electric box, water pipes, and floor drain. Select Destroy Object (Debug) and VIOLA! They are gone and will stay gone.
