Any way to have more than 8 sims in a household?

Haven't seen one yet - it would need a mod. I'd suggest checking Mod the Sims and mod forum here. You could consider managing them on rotational play in multiple houses in a neighbourhood. Think of the neighbourhood as a family compound.

I have three guys in a polyamorous relationship. No jealousy... but no marriage either.

I suppose with your sim, you could do as some US Mormons do and have your sim legally marry his first wife and throw parties as 'spiritual weddings' to the others.

Yes, you can have more than 8 Sims in a house. Just use the cheat: sims.Spawn
This will spawn a random Sim in your household. You can then just use cas.fulleditmode to change him/her to your liking.

... or you move your sims' other wives and children into the houses next door... happy switching!

you don't need a mod. do sims.spawn then cas.fulleditmode and then go to CAS. you can now edit sims, making them as old or young as you please.

You can spawn more sims but, they will not show up in CAS. Only 8 sims show up in CAS at a time and they will be the original 8 family members, even with the cas.fulleditmode cheat.

Hello
MCCC mod allows more than 8 sims
MCCC > MCCC Settings > Gameplay Settings > Maximum Household Size

This setting allows overriding the default EA maximum household size of 8 to another value, up to 25. Note that when you have more than 8 Sims in a household, there are some in-game issues dealing with CAS. You have to use 'Modify in CAS' for the Sims that are after the first 8 in the household from the 'Sims Commands' menu. When a new update from EA comes-out, if you try to use the update when MCCC isn't updated, it could cause problems dealing with these households. This is the same as any household size change mod, but I just wanted to make sure it was noted here that these things should be kept in mind.

If my household size is set to above 8, how do I edit Sims in CAS so the game doesn’t delete all the Sims past the 8th in the household?

All of the core game’s “Edit in CAS” basic functions have household size hard-coded to 8. So no modder can prevent those functions from deleting extra Sims. However, there is a different “CAS Edit” that allows editing those large household sizes without losing extra family members. You would use that CAS edit rather than “Manage Household” or a dresser or a closet or a mirror or anything else. The safest thing to do is just use MCCC to edit the Sim rather than a Sims 4 method. The option for editing a single Sim in MCCC is "Modify in CAS". It is available in the initial MCCC Sims menu when clicking on a Sim in a household that has more than 8 Sims in it. It can also be found in the “MCCC > Sim Commands > Modify in CAS” path for any Sim.

Once you have installed the mod, have your sim click on a computer in their home. Then click on the MCCC option. Then click on the MC Command Center section. Then click on MCCC settings, then MCCC gameplay settings, then maximum household size .
