ubiquitin – Although what you wrote is “common knowledge” to some, it is not correct and based on a misunderstanding of a braysa in shabbos. The braysa says: “??? ???? ???? ????? ?? ??? ?????”. The word ??? there household, as in one’s family. Some mistakenly understand it to mean “house”, as in the physical place in which one dwells. But of course this is a mistake, as is clear from an even casual reading of the Rambam, the mechaber, etc. I understand that some very recent poskim believe otherwise, but this is really a huge chiddush and against the gemera itself and rishonim.
