What most have to do, is work with the condo board and come up with an install cost and a surcharge (usually since the wiring has to be hooked to the building meter, not yours). It can be a bit expensive and difficult to get done, but I know many that have done it. Myself, it cost me about $2,500 to wire up high amperage charging in my condo building, and they were able to get it on my own meter.
If you find any other buildings in you inquiry, I would love to hear about it. I am committed to green tech in my real estate business, and want to continue to learn as much as I can to provide for my clients needs.
Great question. I know of a gentleman that has a Tesla in a rental. He got permission from the building to be able to plug in. You may want to reach out to few buildings to see if they would allow your client to essentially plug in. The catch is any modification needed will have to be done at your clients expense just was if it was his/her own home.
