Experience/thoughts on converting residential to commercial elevator?
We're looking at converting a very large house to office use.  The house currently has a residential elevator.  I'm thinking that we may have to convert to a commercial elevator.  Anybody done this or have some thoughts/experience on what this might cost?  

Not withstanding cost, the plans look like there would be plenty of space - various rooms around the current elevator on all floors appear sufficiently large.

I kind of imagine you have dealt with elevators before knowing you, but if not get ready for some sticker shock.  The last one I had to deal with I think we paid $500 /hr or around that for them to inpsect/consult on then got a quote around 35k to bring up to code/functional which was just replacing the controls.  Not to say that can't make sense in your project costs, but expect this to be a 10's of thousands type thing.  Thats assuming you don't need to move walls for a larger shaft, if that is the case then I assume you have some idea on what that costs per the property.", "replies": [{"id": "gxr1pa3", "text": "I do have some elevators out of this core market.  Like you say they're on service contracts and yeah, expensive.  Like I say, this one is in a resi structure (giant house).  I'm more concerned that it's 6 figures.  Will definitely call elevator guys as well.", "replies": [{"id": "gxr31vf", "text": "&gt; I'm more concerned that it's 6 figures.\n\nThats not a bad assumption.  Do you have an architect on this?  They should have some idea I'd think too just as far as if it meets ada or needs major changes.", "replies": [{"id": "gxr41rt", "text": "Not yet.  It's not going to need a huge amount of mod we don't think for our intended use.  When we get to under contract diligence we'll start spending some of that money.", "replies": [], "depth": 4}], "depth": 3}], "depth": 2}], "depth": 1}, {"id": "gy393vt", "text": "You can engage an elevator consultant to assist with an initial review and recommendations. They would know more details than an architect. Likely you would need to review maximum capacity, ADA, and overall increased requirements for safety (fire recall), etc.", "replies": [{"id": "gy4i2xh", "text": "thanks.", "replies": [], "depth": 2}], "depth": 1}]
