Va. Code § 55.1-1411
No covenant or promise by a lessee of nonresidential property to pay the rent, or that he will keep or leave the premises in good repair, shall have the effect, if the buildings on the premises are destroyed by fire or otherwise, in whole or in part, without fault or negligence on his part, or if he is deprived of the possession of the premises by the public enemy, of binding him to make such payment or repair or erect such buildings again, unless there are other words showing it to be the intent of the parties that he should be so bound. But in case of such destruction there shall be a reasonable reduction of the rent for such time as may elapse until there are again upon the premises buildings of as much value to the tenant for his purposes as what may have been so destroyed, and, in case of such deprivation of possession, a like reduction until possession of the premises is restored to him.
