基本上根據紐約州Landlord - Tenant Law
http://www.consumer.state.ny.us/clahm/clahm-landlords.htm
如果您是Renting Without a Written Lease，根據法律在您終止租約前您需要在搬遷前一個月給房東一個書面通知，詳細的規定老貓付錄如下

(When two parties enter into a landlord-tenant relationship without a written lease, this arrangement is known as a "month-to-month tenancy." In this type of tenancy, the tenant continues to maintain possession of the property for successive monthly periods, beginning on a specific calendar day. If either the landlord or the tenant gives one calendar months notice of termination of the arrangement on the day beginning the arrangement, the arrangement will terminate at the beginning of the next monthly period. If, however, notice of termination is given to the tenant less than one calendar month before the beginning of the next "month to month" period, the tenant may remain in the apartment for an additional month. For example, if a landlord terminates a month to month tenancy on May 15, the tenant may remain on the premises until July 1.)

老實說在這個事件中，除非租賃公司特別讓步，(老貓不認為對方有任何原因願意讓步) 您基本上在法律上無法取回您的押金。如果要怪，只能怪您自己沒有查清楚所有的資料，記住一點，除非您自己花時間查考所有的資料了解您自己的權利，沒有人有義務告訴您應該如何做，所以老貓誠懇的希望您日後能夠記取教訓，對於自己的權利不要輕忽。
