Whether you use your own lease or a model lease provided by BHA, the lease will state how much notice you must give your tenant if you want to terminate the lease. The eviction process is the same for a family with a Voucher and an unassisted family. You may consult an attorney or bring the matter to the local Housing Court. You do not need BHA's permission to evict a tenant who is in violation of the lease. You should send BHA copies of the eviction notice.
