This question came is for a one and two family home. They want to have an elevator serve the roof. This space would be for viewing the nature around the home.
Which building or residential code is it built to?? and which year edition
I am thinking no.
NFPA 1 and 101 (2015)
Suggest you ask the question here also:::
look at R311.1 and R311.4
Egress balcony, do not think you want to try to meet its requirements:
No way to access it from an upper room door or sliding door??
They would like to add a glass elevator to the exterior of their modern house for accessibility / aging in place. They are interested in using the elevator to create roof access and roof deck as well, which they do not currently have (save climbing up on ladders).
Thanks for your help on this, clearly they are not going to like the answer.
Best is to access it of an existing room.
Or add a little money to the job and do stairs, to make the government happy, and also have an elevator.
Do they happen to live on a few acres, or are the neighbors in a stone throw??
same language in the 2009 IRC
suggest post the question at the link above for some other ideas
So the elevator would both be the only access and egress from the roof? Seems like a very bad idea. That would create and area without a single primary means of egress. The balcony may serve as a means of escape, but the elevator would not be a true primary means of egress. Also, for it to even be a means of escape it may need to be accessible by FD apparatus (ie: would a FD aerial device have access 24/7/365 or does the yard prevent this?).
I would think having a true set of stairs, plus the elevator for those with mobility issues may be the right combination? Is the home sprinklered? That would eliminate the need for a secondary means of escape in NFPA 101.
