Residential Zones

Residential Zones

Updated for Tokyo Town

This is the essential foundation to your city, laid down to build the zones sims call home.

  • You can have a maximum of three (3)[this maximum also effects TTZ] plots ready for construction laid out
  • Upgradeable by completing building plans that require certain resources and materials
    • You can request to have new plans drawn (wait time: 30 minutes, cost: free)

Tokyo Town update added a new neighborhood zones called the Tokyo Town Zone (TTZ)

  • 20% more population than the standard zone
  • Uses 2 units of utility capacity
    • 1 more than standard zone
Be careful not to overextend your city by creating new zones without adequate services (explained later here) to support them.

Upgrading Residential Zones

After you place your first couple homes, its Sims will eventually want to move into bigger and better housing. This is where upgrading comes into play.

  • Once sims are satisfied with their current home, they become ready for upgrade
    • A yellow construction hat in a speech bubble will appear above the zone showing a plan
      • Plans contain one or several required resources (explained in the next section here) that you create at factories that must be collected and used to upgrade
  • Upgrades grant Simoleons (§), population increases, and XP upon upgrading
    • Population Increase per upgrade is consistent throughout the upgrade schedule
    • Simoleons and XP per upgrade is variable based on your level throughout the upgrade schedule
  • There are 5 upgrade levels before a residential zone is at ‘max’ level. Once at max:
    • Cannot be upgraded further
    • These are skyscraper/high rise buildings

Wealth and Land Value

For a step by step guide, please check out our post on How to Build Skyscrapers!

There additionally are two factors that determine the type of residence that will appear after an upgrade.

  • Land Value
    • A measurement of the how valuable and attractive particular areas of your city are
      • Higher land values lead to higher wealth buildings (see below)
    • Measured in a white to dark blue spectrum (low to high land value)
    • Increases to land values
      • Providing Coverage Service Areas
      • Specialization Boosts and clean areas (no dirty area/pollution) increase land values
    • Decreases to land values
      • Lack of Coverage Service (Fire, Police, Health) lowers land values
      • Lack of Specialization boosts does not lower land values (does not increase them)
      • Dirty areas/pollution lowers land values
  • Wealth Forecast
    • A measurement of how wealthy residential zones currently are
      • Can also be used to indicate what type of home they will be when upgraded
    • Wealth is based on land value
Be sure to check your upgrade population reward (Around +1800 population means it is about to upgrade to the Max level) followed by the Wealth Forecast screen (make sure you are in luxury & high land value areas) before max upgrading buildings to ensure you achieve the highest tier residence.
Once a building is about to upgrade to the maximum level (+1800 Population) it will take the form of its current home type (Standard, Premium, Luxury)
If your building is not at the maximum tier, You must BULLDOZE the building and start from scratch if you want to raise the home type
Home Type
Tier (T) Name Requirements
T1 Standard Homes All coverage service requirements have been met
T2 Premium Homes All coverage service requirements have been met
Covered by 1 specialization boost
T3 Luxurious Homes All coverage service requirements have been met
Covered by 2 specialization boosts


You CAN move residential zones into areas that have luxurious wealth forecasts and high land values to upgrade to the maximum tier and then move them out afterwards
