For an indoor residential elevator, the number of stops is not set by one universal rule. ASME A17.1/CSA B44 provides safety requirements, but the applicable edition and local amendments depend on the jurisdiction. The elevator’s classification and approved building plans also matter. A home with three levels may need service to all three, or only selected floors, depending on the intended design and local approval.
Check the required stops early. Each stop affects the landing openings, door interlocks, clearances, controls, and travel distance. A technician or design professional can compare the floor plan with the adopted code and confirm what the local authority requires. Ask how the proposed layout handles a garage level, basement, or split-level landing. Small changes on paper can affect shaft dimensions and construction later.
Details matter. A closed landing door should stay secured when the elevator is elsewhere, and controls must suit the approved installation. Emergency provisions and inspection requirements also need review. Keep the approved drawings and equipment specifications available during planning. Requirements can vary, and a sales estimate is not a code determination. It is easy to overlook one half-level. Check it twice.
