Sub-neighborhood

A sub-neighborhood is a neighborhood that can't exist solely on its own. Sub-neighborhoods were first introduced in The Sims: Hot Date, and each subsequent expansion pack for The Sims added a new one which fit that pack's theme. They were designed as places for community lots and townies to be, and as places Sims could travel to and from.

In The Sims 2, playable sub-neighborhoods are not automatically associated with a neighborhood. The player must decide which, if any, sub-neighborhoods of a given type will be associated with a neighborhood. The Sims 2: Nightlife and The Sims 2: Open for Business each included a sub-neighborhood intended to showcase aspects of that pack. However, they also expanded the main neighborhood, giving Sims more places to live as well as more places to go. The Sims 2: University and The Sims 2: Bon Voyage included sub-neighborhoods designed to give Sims places to go to college and on vacation. These types of sub-neighborhood are "restricted"; Sims can only go to them under certain circumstances, and can only live in them for a limited time. The Sims 2 also gives players the ability to create custom sub-neighborhoods of any type using terrain templates that were included with the game, or by using SimCity 4 to create custom terrains.

In The Sims 3, sub-neighborhoods are included in the World Adventures, University Life, and Into the Future expansion packs. Like the vacation and college sub-neighborhoods in The Sims 2, the sub-neighborhoods in World Adventures and University Life only allow Sims to live in them for a limited time. However, the sub-neighborhood for Into the Future allows Sims to stay indefinitely.

Except for college sub-neighborhoods in The Sims 2: University, 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.)

Each community area has its own cab service and its own rules about who can go to it, so it is not possible to travel directly from one to another.

The Sims community areas, by expansion pack, are:

The Sims 2
If Nightlife or later is installed, Sims can travel directly from any sub-neighborhood they can reach by taxi, car, or walking to any other sub-neighborhood that can be reached in the same way.
