Question
Hi!  My husband and I are preparing to build a green-as-possible home
on a challenging lot (25' max for house width).  Since we will build up
and are retired (but very active and healthy now) and planning to  live out
our lives there, we are considering adding an elevator.  We hear it's best
to do so during construction rather than as a retrofit.  Can you give us
any guidance -- type, anticipated cost, space to allot, things to avoid?  
Thank  you,
Katherne

Answer
Katherien,

There are a variety of residential elevators on the market.  From a general planning standpoint, allot a continuous shaft of about 5' x 5' (inside dimensions) through all the floors to be accessed.  If you will have a basement, include that area as well.  

It is difficult to add an elevator to the interior of a house as a retrofit.  Many buildings have exterior shaftways for this reason.  If you can, incorporate the elevator into the design from the start.  

Pricing will depend mainly on the travel height and the level of finish of the car.  You should find one or more elevator companies in your area and ask for pricing.  Expect to pay in the $12K to $25K range.  Residential elevators generally use vertical tracks to support and guide the car, and their capacity is fairly low, usually around 500 lbs.  

You or your contractor should construct the shaft and the well (the floor recess at the base of the shaft)exactly to the brand specifications, and provide adequate electrical power.  Framing normally includes heavy-duty vertical blocking.  Check with your local code official for fireproofing requirements.  You may need to line the shaft with one or more layers of Type-X drywall, and size the shaft accordingly.  

The elevator company normally installs the system and warrantees it.  

Good luck!
