could they put power usage meter on the powerpoint in their car space they use to record : date, time & power used to charge their Tesla and reimburse the OC for the electricity used till the bylaws are passed in 8 months time ?
Absolutely. And make sure they know that you can seal off the power supply if they just try to “steal” the electricity. There’s a lot of info about EV charging here on the website so have a look around.
And think about contacting our strata law sponsors who will be able to offer you an off-the-peg by-law that may be more reliable than a second-hand one for a different building.
