Planning a home elevator

New construction versus retrofit

In new construction, the elevator can be placed where it works best, the hoistway framed with the house, and the pit poured with the foundation. Even if an elevator is not installed immediately, many owners frame a future hoistway—often as stacked closets—so the cost later is mostly equipment and installation.

In an existing home, the location is usually a compromise between where the elevator is wanted and where structure, plumbing, and finished space allow it. Common approaches are stacking a hoistway through closets, building onto the exterior, or using a compact through-floor system that reduces construction.

Selecting the elevator location

A good location usually:

• lines up vertically on every floor it serves
• opens onto circulation space—a hall or landing—rather than the middle of a room
• avoids major beams, plumbing stacks, and duct runs, or makes rerouting them practical
• leaves clear, level space in front of each landing door, especially for a wheelchair
• works with what is below (basement, crawlspace, or slab) for any required pit
• can be reached by service technicians without disturbing finished rooms

Number of stops and approximate vertical travel

List every level the elevator should serve, including a garage or basement. Then estimate travel: the vertical distance from the lowest finished floor to the highest. Floor-to-floor height—not ceiling height—is what matters. Both stops and travel affect price, and many compact systems have lower limits on both than hoistway systems.

Door orientation

Note the direction each landing faces. If every floor’s opening can be on the same side, the elevator is simpler. If one floor needs an opening on the opposite or an adjacent side, the cab must be configured for it. Opposite-side (through-car) openings also let a wheelchair user roll in on one side and out the other.

Cab capacity and accessibility needs

Think about the most demanding use, not the typical one. A compact cab may suit one or two standing adults; a wheelchair, a companion, or furniture may need a larger cab with a higher rated load. Measure any mobility device, including footrests, and compare it to the cab’s interior dimensions and the door’s clear opening. Consider automatic gates or doors and controls reachable from a seated position. Accessibility needs are personal; an occupational therapist can help where appropriate.

Machine and controller space

Some drive systems need a separate closet or room for a pump, motor, or controller, which may need ventilation, lighting, and to be within a set distance of the hoistway. Machine-roomless designs reduce this, but most still need a controller location and service access. Confirm with the manufacturer’s planning guide.

Pit and overhead requirements

Many hoistway elevators require a shallow pit below the lowest landing and a minimum clearance above the top landing. Some compact systems are designed to sit on the floor without a pit. Requirements vary significantly by product and code, so verify them before finalizing a location—especially in a retrofit where a slab must be cut or a ceiling raised.

Hoistway construction

Where a hoistway is needed, it is usually built by a general contractor to the manufacturer’s drawings: framed walls, any required fire rating, blocking or structure for the rails, the pit, and finished openings at each landing. Agree early on who builds what and when the hoistway must be ready for installation.

Power requirements

Expect a dedicated circuit and a disconnect, and often lighting in the hoistway or machine space and an outlet for service. Many codes also require a way to call for help from inside the cab, which may need a phone or data connection. A battery-lowering or backup feature may be standard or optional. A licensed electrician should work from the manufacturer’s electrical requirements.

Local permits and inspections

Many jurisdictions require a permit before installation and an inspection before the elevator is used; some also require periodic inspections. Requirements depend on local code and the product type. Clarify who applies for permits—the dealer, the general contractor, or the owner—and build inspection time into the schedule.

Dealer and installer coordination

Residential elevators are commonly sold and installed through authorized dealers. The project typically moves from consultation and product selection through approval drawings to installation. Three parties often need to coordinate:

• The dealer or installer: product selection, drawings, equipment, installation, inspection support, and service.
• The general contractor: hoistway or floor opening, structure, pit, finishes, and site readiness.
• The electrician: power, disconnect, lighting, and communication connections.

An architect or designer may also be involved, especially in new construction.

Service access

Elevators need periodic service. Plan clear access to the controller, machine space, and pit, and confirm that an authorized service provider operates in your area before you choose a product.

Finish coordination with the home

Coordinate cab panels, flooring, lighting, landing doors, trim and fixtures with the house. Decide early which finishes the dealer supplies and which the builder supplies, and confirm lead times.
