Unless the lease contains a restriction, the tenant may use the premises in any legal manner. In his use of the premises he may not, however, interfere with occupants of other parts of the building. Illegal use would permit an action for dispossession by the landlord and a lease specifically made for an illegal purpose would not be enforceable by either party. The purpose for which the premises are to be used is often stated in the lease, as for example, "private dwelling," "boarding-house," "retail drugstore," etc. In this connection, where it is desired to limit the use of the property to some specified purpose it is well to have the lease state that the premises shall be used for the purpose mentioned, and no other. It was held that where the lease simply stated that the tenant was to use the premises for a certain trade that when that had been done he could use it for other trades. The lease may contain a covenant that the premises may not be used for any purpose extra hazardous, or objectionable, or detrimental to the neighborhood, or a provision of similar import.
