Yerushalmi Bava Metzia 8:9 ירושלמי בבא מציעא ח׳:ט׳

MISHNAH: He who leases a dwelling to another person and it collapsed has to provide him with a dwelling. If it was small he may not make it large, large he may not make it small. One room he shall not make into two, two he may not make into one. He may not reduce the number of windows nor add to them except with the agreement of both parties.

HALAKHAH: “He who leases a dwelling to another person,” etc. Rebbi Simeon ben Laqish said, if he puts him into it⁵⁰The strict requirements of the Mishnah only apply if the lessor makes a sales pitch about the qualities of the particular dwelling.. Rebbi Joḥanan said, if he told him, a dwelling like this I shall lease to you⁵¹Even if only the kind of dwelling is mentioned.. But if a person leasing a house wants to sell it? Rebbi Immi said, nobody thinks that this one should die of hunger⁵²For him, a sale breaks a lease.. Rebbi Ze‘ira and Rebbi Hila both say, while certainly it is acquired by him, he has to tell him, let him dwell there until the time of his recall^53,Greek ἀνάκλησις “recall, restoration”. ‘Or zarua‘ reads עַד מִישׁלַם זִימְנֵיהּ “until his time is up.”⁵⁴While a sale during a lease is certainly valid, there is an obligation of the seller to include a paragraph in the sales document which protects the tenant for the remainder of his lease.. There came a case before Rebbi Nisi⁵⁵This probably should read: Assi, with ‘Or zarua‘, Rosh, and the later text. and he did not accept this. Does he disagree? They said, his daughter was given as a pledge to a Roman [and he did not have the wherewhithal to redeem her and Rebbi Assi instructed to sell;] therefore he instructed following Rebbi Immi⁵⁶In an emergency one follows R. Immi. The rule of RR. Ze‘ira and Ila is a recommendation, not the law. This is implied in R. Immi’s formulation..
