A Notice of Non-Renewal of Lease is commonly given by landlords when they intend to take possession of the property for personal use, undertake significant renovations, or simply wish to lease to another tenant at a higher rate. In most cases, the landlord is not legally required to provide a reason, but the notice must still comply with the terms set forth in the lease agreement and New York City rent laws. If you receive this type of notice, it’s important to act promptly. First, check the notice for the required time frame, as landlords must typically provide ample notice—usually at least 30, 60, or 90 days, depending on the length of your tenancy. If the landlord has not followed the proper procedure, the notice may not be valid.
