Method for operating an elevator for an inspection, wherein the elevator comprises - a cabin being displaceable along an elevator shaft, - a drive engine for displacing the cabin, - a plurality of shaft doors, at least one of the shaft doors being arranged at each of multiple floors including a lowermost floor and at least one upper floor (21", 21′′′), each of the shaft doors having an associated active door drive for reciprocally opening and closing the shaft door, - a plurality of signal receptors, at least one of the signal receptors being arranged at each of the multiple floors, - an engine controller for controlling an operation of the drive engine, - a door controller for controlling an operation of the active door drives of the shaft doors, the method comprising: - receiving a requesting signal at one of the signal receptors located at one of the floors, - in reaction to the receiving of the requesting signal: - if the one of the floors is not the lowermost floor, instructing the engine controller to control the drive engine to displace the cabin to a first position such that a roof of the cabin is adjacent to the shaft door at the one of the floors, - if the one of the floors is the lowermost floor (21 '), instructing the engine controller to control the drive engine to displace the cabin to a second position above the lowermost floor, - then, instructing the door controller to control the door drive of the shaft door at the one of the floors to actively open, and - switching the engine controller to an inspection mode. wherein the elevator comprises - a cabin being displaceable along an elevator shaft, - a drive engine for displacing the cabin, - a plurality of shaft doors, at least one of the shaft doors being arranged at each of multiple floors including a lowermost floor and at least one upper floor (21", 21′′′), each of the shaft doors having an associated active door drive for reciprocally opening and closing the shaft door, -
