Yes, they are enforceable provided the landlord serves the tenants with written notice no more than 30 days and no less than 15 days from the tenant’s option date to renew the lease. A 60-day automatic renewal clause may be listed in the lease as well. If a lease contains this, the tenant must notify the landlord 60 days prior to the end of the lease with intention to stay or leave. If the tenant does not notify the landlord, the lease will be automatically renewed. The NHO has a non-renewal form in the office that can be filled out and sent to the landlord, giving them a formal notice.
