If during the lease it should become necessary to make some urgent repairs upon the thing leased, which cannot be deferred until the termination of the lease, the lessee is obliged to tolerate the work, although it may be very annoying to him, and although during the same, he may be deprived of a part of the premises.
If the repairs last more than forty days the rent shall be reduced in proportion to the time - including the first forty days - and the part of the property of which the lessee has been deprived.
When the work is of such a nature that the portion which the lessee and his family need for their dwelling becomes uninhabitable, he may rescind the contract if the main purpose of the lease is to provide a dwelling place for the lessee. (1558a)
