Yes. I used documents like the one published by Government of Karnataka (points j and k on page 13) asking all apartments to have arrangements for EV charging. I knew my apartment building had no immediate plans to set up dedicated charging area, so I impressed upon them how it is inevitable then that they allow for private charging. Once I convinced them that they are already behind times when it comes to EV mandates, it was kinda easy to take it forward from there
In your case though, since they are claiming to have plans for common charging infrastructure, it might be difficult to sway them. I think Ather might have to help here again on any government document they might be aware of that speaks of EV charging point installations being allowed and encouraged in apartments.
I am assuming you have already tried this, but why don’t you use this charging dot FAQ which is a part of the broader Ather FAQ to convince them of how safe this is? They need to understand that there are already more than a thousand Ather Dots (apart from those for other EV manufacturers’ vehicles) installed in Bengaluru, and it’s not you have a dedicated section in local newspapers on “Ather Dot fires of the day”…
