Quick answer
Lease expiration does not answer every right to remain or every notice requirement.
Do now
Identify regulation, property type, lease terms, subsidy, and local coverage. Preserve renewal and termination notices. Ask whether the landlord needs a legal ground and whether the notice meets requirements.
Local note
NJ anti-eviction protections and exceptions, NY regulation/Good Cause, and DC statutory grounds differ. Watch for: Do not assume you must immediately leave, or that you can remain indefinitely in every type of housing.
