An elevator renovation method, which is capable of reducing a renovation period and enabling effective use of a space when an existing hydraulic elevator is renovated to a non-hydraulic elevator. The elevator renovation method involves renovating a hydraulic elevator in which a plunger provided integrally with a car is hydraulically driven to a non-hydraulic elevator. The elevator renovation method includes; providing a driving device for generating a driving force for raising the car; leaving the plunger so that the plunger can be raised and lowered inside an existing jack; and obtaining the non-hydraulic elevator by exerting the driving force of the driving device in a direction in which the plunger is moved up to raise the car.
