A machine room is an area where the elevator drive unit and controller are located. Typically for residential elevators a machine room will be located on the lowest landing.
Standard machine room layout for a residential hydraulic elevator.
The minimum recommended size is 5′-5″ deep and 4′-6″ wide shown in this plan. The dimensions allow for a safe working clearance around the electrical equipment required by the national electrical code or N.E.C. BEFORE constructing a machine room space the dimensions should be verified with current electrical, elevator and local building codes. The easiest way to verify current codes is to consult with your elevator contractor.
