The 14-day notice to vacate must be written clearly and follow strict New York law. This notice must also be served personally to the tenant and state the reason for eviction, the rent due, and the departure date. Landlords must also prove the tenant received the notice.
For a tenant that's been in possession of the premises for 2 years or more, the notice must give at least a 90-day notice for tenant to vacate before commencing the eviction case.
If you don't intend to renew the lease, you must give notice to vacate. This must be in writing and delivered to the resident before the lease expires. In certain states like California, a 60-day notice is required if the resident has lived in the unit for at least a year.
