The long form of lease given in the appendix provides that the tenant shall give the landlord immediate notice of any fire. It is then the landlord's duty to repair the damage as speedily as possible. If the tenant remains in possession, the rent continues regardless of the fire, but if the damage is such that the tenant is compelled to remove, the rent ceases until such time as the property is restored to its former condition. In cases of total destruction of the property by fire, the lease is terminated; rent is paid up to the date of the fire and thereafter the liability of the parties ceases. It is advisable to include a fire clause in the lease so that the rights of the parties on the happening of such an event are clearly defined. In some States the law provides that a fire which renders the premises untenantable terminates the lease. If there is no such provision of law or if the law provides the contrary, the lease of the premises continues regardless of any damage by fire.
