How should I budget a curbless accessible route during new construction?

The empty conduit for a future lift or door operator is useful, but it should be paired with an electrical-capacity allowance. Otherwise the conduit may terminate at a finished panel with no spare spaces, insufficient load capacity, or an inconvenient disconnect location.

I’d have the electrical drawings identify:

- A reserved breaker space, with the anticipated voltage and load noted.
- Panel and service capacity for the likely lift or operator, subject to the equipment manufacturer’s final requirements.
- A reachable disconnect location and a continuous, accessible route from the panel to the equipment.
- Separate provisions for controls, sensors, lighting, or communications if the selected equipment needs them.

For a door operator, the rough-in can often be modest. A lift is less predictable, so the structural location and electrical allowance should be based on a realistic equipment category rather than a generic “future lift” note. That keeps the conduit from becoming a false economy.
