I plan to add extra ones for families living there too. I generally use Reduce & Recycle (waste overflows and attracts pests if not managed) and Simple Living for everyone, as well as the Homey trait if they don't have staff to cook/fix etc. I also use Filthy for Gardeners/Farmers/Slobs, Grody for Slobs and Spooky for older homes where sims likely died etc too.
However, as I'm making all the worlds blank for this, I figured each world/zone could have a base-level status too.
I can also cross-reference Lot Challenges with Lot Traits or terrain/build features. For example, a lot with Volcanic Activity has the potential for Geothermal Energy, but it wouldn't make sense somewhere else. Lots with ponds/lakes/moats/streams might have them because of a Natural Well, or a home with a lot of windows and no dense landscape might receive a lot of Natural Lighting.
I'd rather make the Traits/Challenges fit the lots/area first, and have sims move in based on that as it seems a more cohesive and parallel-to-real-life way to do things. NAPs could then develop appropriately after based on those who move in there, further impacting who wants to live there.
