general guidance will apply to strata residents in other states.
There is an amount of fudging of the level of approvals required in Victoria. The guide suggests that only a simple majority is required when instaling EV charging through the general maintanance provisions, but a special resolution (75% of votes) may be required when there is a level of complexity and disagreement.
In NSW, EV charging is specifically identified in strata law as a sustainability measure and therefore the required common property by-laws only require a simple majority. Impending legislation will see that flexibility extended to individuals who wish to install their own EV charging in their parking bays.
