That to me seems to be a harsh and unjust by law
We have a similar by-law in our environment award winning block because it was designed to be naturally cooled by a flow-through of air. However, it doesn’t work in all the apartments, it’s hard to control where it does, and there’s this thing called Global Warming that everyone is talking about.
But here’s the thing, because it was designed not to have air-con, the electricity supply isn’t up to providing the necessary power. The majority of owners would love to have air-con but aren’t keen to pony up with the couple of million bucks for a new substation.
I wonder if the OP’s scheme is in a similar situation, and all the nuts and bolts stuff is just another way of saying “no way”. If it does have similar limitations, the by-law is neither unreasonable nor oppressive.
