From Melbourne.
We had an escalating situation in 2020 from people using their own private carports for impromptu (illegal) gatherings on Friday nights over lockdowns, they would sit in the (near) darkness, drink and talk louder and louder as the evening rolled on sometimes past midnight, disrupting everyone’s sleep in nearby units. It was quite sad really. Given VicPol had other priorities in the middle of COVID lockdown # x (whatever one we were up to at the time), they were not interested.
But it did prompt the question to the Owners Corp Mgr as to what we were allowed to do in our own (privately owned and on title) car ports viz-a-viz as a place for a party. It turned out there was a by law (not sure if it is model or custom) that indicated that a car port or garage is only for the storage of a car, perhaps with the poor acoustics of the common area in mind. An email went out and the parties soon came to a halt, perhaps the threat of the OC reporting the illegal gatherings to the police also helped (admittedly, we were less bothered by the exercise sessions of neighbours as to be fair there was nothing else to do in lockdown…). But it was something we were completely unaware of as a community before this.
Question for you is: Do you have any such rules about car port or garage usage in your complex? Is that something you could explore with your OC Manager?
In answer to your question about quiet enjoyment, I’d say it comes into everything (within reason). And perhaps see if you can invite your neighbour for a coffee and have a chat, or a beer and chat (whatever floats your boats), it might be a simple solution!
Best of luck!
