Talented The Sims 4 Mod Creator TwistedMexi created a long-awaited mod that lets you modify the number of Sims in your Household!
The regular version of this mod only lets you have 9 max Sims in your household (just so your game is more stabile), but you can always choose the experimental version of this Mod and have up to 24 Sims in your Household!
