Conn. Gen. Stat. § 29-196
As soon as the department approves any new, relocated or altered elevator or escalator as being fit for operation, it shall issue to the owner a certificate of operation for a capacity and speed specified in the inspector's report. The fee for the certificate first issued shall be two hundred fifty dollars. Such certificate shall be posted conspicuously in the car or cage or on the platform of the elevator or escalator and shall be valid for twelve months. Thereafter, the certificate shall be renewed every two years upon receipt of the renewal fee of two hundred forty dollars, except that elevators located in private residences shall not be subject to said renewal requirement. No fee shall be required of the state or any agency of the state. No elevator or escalator may be lawfully operated without such certificate.
