I am in a similar boat as the OP. I live in a condo, too, and the condo board has not seen fit to install a charger yet. The main issue here is lack of any suitable spaces. We are already short on visitor spaces so the board (quite rightly) does not want to take away a visitor space for use by a charger. (Shared use could be the solution but we did not get to that.) My own parking space is in an open lot far enough from any power supply that bringing power to it would be ridiculously costly (if allowed, and there is no guarantee it would be since power to my space would need to run through spaces owned by several other people). I also got assurances from my Tesla sales people not to worry about it and to use my local Supercharger, only a couple of miles away. I was not too concerned because I do not commute to work and have modest weekly travel needs. BUT -- then the infamous letter came out, just about when I had finally decided to order. I went ahead, but am a bit worried about how it will work out. SC charging may prove impractical, or Tesla may give me a hassle, etc.
Also, I strongly agree that Tesla (and the rest of the EV industry) will encounter this issue even more with Model 3, because the people it is aimed to are more likely to live in multi-unit housing than are the Model S owners. New buildings can be designed to accommodate charging, of course (if the owners or developers feel the need for that), but older buildings like mine are a more difficult proposition.
