@T0roko - Are you using or open to using mods at all? Under EA standard, we have no control over what happens to households who are inactive (not player controlled). Of course the tools are there for players to rotate gameplay around different households making them active in turns, but it often enough just doesn't work out well when the households rotated through fall apart or move out of the world when those would be the last things that the player would want.
NRaas mods provide tools to prevent these things from happening, but one has to embrace the NRaas kind of story progression for them to be effective.
