The Sims 4 does not currently have a widely used, functional mod that directly increases the 4-floor above-ground build limit. While older games like The Sims 2 had specific cheats for this, The Sims 4 remains restricted to and 4 stories below ground (basements), allowing for a total of 8 levels per lot.
