Home Elevators & Vertical Platform Lifts: Complete Guide
Updated June 2025 — Permits, types, and costs
Three Types of Residential Vertical Access Devices
| Type | Travel | Cost Range | Shaft Required? | Permit? |
|---|---|---|---|---|
| Vertical Platform Lift (VPL) | Up to 14 ft | $8,000–$18,000 | No (open design) | Yes — all states |
| Pneumatic Vacuum Elevator | Up to 35 ft (3 floors) | $15,000–$35,000 | Freestanding cylinder | Yes — all states |
| Traditional Cable/Hydraulic Elevator | Up to 50 ft (5 floors) | $25,000–$60,000 | Yes — hoistway required | Yes — all states |
Vertical Platform Lifts (VPLs)
VPLs are the most common accessibility solution for between-floor travel when a stair lift is inadequate (e.g., for power wheelchair users who cannot transfer to a seat). They are open-platform devices that travel vertically — essentially a small open elevator without an enclosed cab. They can be installed indoors or outdoors and do not require a traditional elevator shaft, making them substantially less expensive than a full elevator installation.
VPLs are regulated as conveyances in all states — meaning a building permit and, in many states, an elevator permit with periodic inspection are required regardless of whether they're installed in a private residence.
Pneumatic Vacuum Elevators
Pneumatic elevators use air pressure differential to move a self-contained cylinder cab between floors. They require no machine room and minimal structural modification — just a ceiling opening between floors. They are energy-efficient (use energy only going up; descend by gravity with controlled valve release) and aesthetically striking. Permit requirements are the same as for traditional elevators in most states.
Traditional Home Elevators
Full residential elevators require a hoistway (shaft) built into the home's structure — either retrofitted through existing floors or incorporated into new construction. They have the highest capacity, the most travel options, and the highest cost. Retrofitting a hoistway into an existing home typically requires significant structural work and is a major construction project.
Permit Process for Home Elevators
Unlike stair lifts (which some states exempt from permits), all residential vertical access devices require permits in all states. The typical process:
- Building permit application with drawings showing the installation
- Elevator permit from the state elevator inspection division (in elevator-code states)
- Installation by a licensed elevator contractor (required in most states)
- Final inspection by a state elevator inspector before first use
- Periodic re-inspection (typically every 1–2 years in most states)
See our detailed home elevator permit requirements guide for state-by-state details.
Yes, though the feasibility and cost depend heavily on your home's structure. Pneumatic vacuum elevators are the easiest to retrofit — they require only a ceiling opening between floors and a small footprint. VPLs are also relatively easy to retrofit in most homes. Traditional cable or hydraulic elevators require a hoistway, which is a significant construction project in an existing home. A structural engineer assessment is recommended before committing to a traditional elevator retrofit.
