Maryland Code, Commercial Law § 2A-221

(a) If the loss is total, the lease contract is avoided;  and

(b) If the loss is partial or the goods have so deteriorated as to no longer conform to the lease contract, the lessee may nevertheless demand inspection and at his (or her) option either treat the lease contract as avoided or, except in a finance lease, accept the goods with due allowance from the rent payable for the balance of the lease term for the deterioration or the deficiency in quantity but without further right against the lessor.
