Re: This house must have at least one fridge and enough bed spaces for all Sims.

@krecha_ae  Are  you using any mods, for example NRaas StoryProgression?  If so, you can disable rigorous home inspection:

SP > General Options > Options: Lots > Options: Inspection > Rigorous Home Inspection > False

Or you can play with the other options in that category.

This is not a base game feature.  I've moved a number of sim households to empty lots over the years and built their houses afterwards, and the game has never thrown any kind of error or warning.

As for bugs getting fixed, no, that's not going to happen.  The Sims 3 development team was disbanded nine years ago, so there's no one around to work on the game's remaining issues.
