How many levels of basement are possible now

As far as I know it's 4.

Four. :)

I think it's 4, but you can only put a swimming pool on levels 1-3 if you're so inclined.

well if you were in the game figuring it out....did you try to see how low you could go while you were in game?

I run lots of CC I removed it all an my floor was still there just wanted to make sure. I have enough issues with the way they have jacked up gardening this time. Without adding a floor some how that shouldn't be there.

@Grumble314 It's 4 up, 4 down. You can put a roof and decorations on top of the fourth level, but not another floor. For down, like @stilljustme2 said, a pool down to the third underground, since it technically takes the -3 floor as it's top but goes to the bottom of the 4th floor down. ;)

I have never gone below one basement level. I wouldn't even know what to do with all those levels! haha

Four. Basement levels were increased from two to four by the Nov. 13, 2018 update.

They should have made it eight floors total, regardless if they’re above or below ground. Five story house? Three left for basement. Two story house? Six left for basement.

I think the most I've done is 2; if you're on a small lot (like a 20x15) it can be hard to fit in all the things you need for skillbuilding (though I have some community lots where I can send my Sims), so the basements make a good place for things like the video game platform, workout rooms, and the like.
