Tenants in New York City often believe that paying rent on time means they will get a lease renewal. This is true for many, especially those in rent-stabilised apartments. A landlord's refusal to renew a lease can be legal sometimes, depending on the situation and if proper notice is given. Still, tenants have strong rights to guard against illegal actions by landlords. To find a home in NYC, it's important to understand a landlord's refusal to renew a lease and when it is allowed or not.
