Is one sacrifice sufficient for the entire family living under one roof?

I was recently sent the below video of **Sheikh Assim Al Hakeem**: https://www.youtube.com/watch?v=uqZnoGt6WYo I am unable to find any Hadith either validating or rejecting the notion in the video. I also saw this answer but it pertains to the Imams and not directly from the Prophet or the Sahaba https://islam.stackexchange.com/a/49417/3259 Hence, can someone clarify if one sacrifice is sufficient for the entire family ***living under one roof***?
