Sub-neighborhood

A sub-neighborhood is a neighborhood that can't exist solely on its own.

Sub-neighborhoods exist in a sort of "time warp". No matter how long Sims spend in one, they will return home no more than a few hours after they left. It's not only possible, but common, for them to return when they left.

The Sims
Sub-neighborhoods in The Sims are often referred to as community areas. Except for Downtown, Old Town, and Magic Town, they contain 9 community lots laid out in a 3x3 grid. (Downtown has 10 lots laid out in a 3-4-3 grid. Magic Town has 9 lots, but three are residential.)
