How to move into an SF apartment with no elevator
Measure the stairs, landing, doorways, and room before you buy furniture or hire help. A sofa that fits the room may not fit the staircase. Ask the building manager about access rules and protect walls where appropriate.
Pack in small, sturdy boxes and keep heavy items light enough for safe carrying. Reserve the largest items for the strongest helpers or professional movers. Clear the path and assign one person to guide at difficult turns.
Build extra time into the day. Stairs turn a simple move into physical work. Water, breaks, and a smaller load are cheaper than an injury or damaged banister.
