You mean the abandoned cabins? These are for sure! Are even on the list above.
However, the second part you said is a little hard to be done in practice. You know, many players would hate to be forced to provide maintence on their houses and bases, so this will have to be optional. And even then, these will give quite an chore to be coded, and who knows how much value such feature will gring to this game. Not a bad idea, but maybe more suitable for a more hardcore game, such as Project Zomboid.
The maintenance to be done in this abandoned cabins was minimal, i found. It took not more then 5 or 10 minutes. If you have the time to build for hours, a few minutes maintenance like you had to be done on the previous version of the game would not to much. Do one not clean his house every week ?
