English

The Law of an Old Sukkah, 2 Seifim: An old sukkah — i.e., one that was made more than 30 days before Sukkos — is valid provided something new was done to it for the sake of the festival (See Sukkah 9a). For this, even a handbreadth by a handbreadth is sufficient if it is in one place and if the new thing was done for all the Sukkah. And if it was done for the sake of the festival, even if it was done at the beginning of the year, it is valid without anything new.

[The following laws apply with regard to] a potter [whose workplace is comprised] of two [adjoining] sukkos, one of which gives access to the other, and he fashions his pots in the inner [sukkah] and sells them in the outer [sukkah]. Though the inner sukkah was built for shade, he does not fulfill [the obligation to dwell] in the sukkah with it because it serves as his dwelling throughout the year. Since he eats, sleeps, and performs most of his activities there, it would not be evident [during the festival] that he is now doing these things for the sake of the mitzvah. He may, however, fulfill his obligation using the outer [sukkah], for he does not dwell in it throughout the year.
