The Sims 3 Household Limit: 8 Sims Max (No Official Cheat)

There is no official cheat to exceed the 8-Sim household limit in The Sims 3. The cap is hard-coded into the game engine.

Workarounds (Use at Own Risk):

1. Mods (PC/Mac only):
   • NRaas MasterController – Allows "Edit Household" > "Set Max Household Size" (up to 50+). Most stable option.
   • No Family Limit – Simple script mod removing the cap.
2. TestingCheats Shift-Click (Adds to Household, Doesn't Raise Cap):
   1. Enable: testingcheatsenabled true
   2. Shift-click a Sim → "Add to Active Household."
   3. This bypasses the 8-limit visually but can cause routing errors, save bloat, and corruption.

Important Warnings:

• Mods can break with game updates. Always back up saves (Documents/Electronic Arts/The Sims 3/Saves).
• More than 10-12 Sims causes severe lag, routing failures, and "Error 12" on save.
• Console (PS3/Xbox 360/Wii) versions cannot use mods; limit is strictly 8.

For large families, consider rotational play (switch active household) or The Sims 4 (base limit 8, but mods like MCCC raise it easily).
