The maximum length of a standard residential lease agreement is one (1) year in Connecticut. Leases can be longer than one year if the term is fixed or agreed upon beforehand by both the tenant and the landlord.
Leases with a duration of one (1) year or longer must be in writing. Oral leases are legal and valid for any duration of less than one year, but it is recommended to put all leases in writing regardless of duration. Oral leases are generally more difficult to enforce.
If no definite term is described in the lease, the duration of the tenancy is month-to-month (when rent is paid monthly) or week-to-week (when rent is paid weekly) (CT Gen Stat § 47a-3b (2019)).
