Commercial Elevator vs Small Residential Elevator
There are 3 major differences to take into consideration when deciding if you want a Commercial Elevator or a more compact Single Family Residential Elevator.
Commercial Elevators are Larger, Faster, and more expensive and single family residential elevators are smaller, generally slower, and have a lower cost.
Standard Sizes for Small Residential Elevators
According to New York City building code elevators in buildings 5 stories or more must be large enough to accommodate a stretcher but this does not apply to single family residences or to LULA Elevators. A LULA elevator is a Limited Use Limited Application Elevator that can only have a travel distance of up to 25 feet.
The following are standard sizes for residential elevators that do not require fitting in a stretcher. These dimensions are for the CAB size not the hoistway dimensions.
- 36″ x 48″
- 36″ x 54″
- 36″ x 60″
- 40″ x 54″
Standard Cab Heights are 80″ or 84″.
Configuration of Elevator Cabs for Residential Use
Based on your Townhouse Layout there are multiple ways to configure your new residential elevator. The doors do not all need to be on the same side.
Structural Work for Adding an Elevator to a Brownstone
If you are adding an elevator to a brownstone of townhouse in NYC the layout of your townhouse will affect the scope of work to accomplish the work. You will most likely have some structural work to do on your townhouse. Most townhouses are built with masonry bearing walls and wood joist. The wood joists will need to be cut to accommodate the new elevator. This is a structural modification. The loads will need to be transferred and this means re-framing the area of floor joists affected. New walls will need to be built to support the elevator and equipment. These can be framed or masonry depending on variables like building size and construction classification.
Fire Protection for Adding an Elevator to a Brownstone / Townhouse
The shaft or hoistway of your new elevator requires fire rating. This will affect the construction and cost. The project architect will provide the required fire rating details to complete the work. At our architecture firm we always make sure this aspect is very clear on our drawings. We also perform progress inspections to verify the correct fire ratings. The Department Of Buildings will require us to provide a Technical Report on required progress inspections and special inspections for the work.

The elevator company will get their own elevator permit for installing the elevator, additionally you will need an architect. In NYC the architect will file for an Alteration Type 2 permit to add a new elevator to ta townhouse, as long as no other work requires an Alteration Type 1.
