I’m not a lawyer either, but I seem to recall that tenants have to agree to abide by by-laws as a condition of their leases. I also know that owners are responsible for controlling the behaviour of their tenants.
So if the tenants breaches the by-laws and the owner does nothing to stop it, like cancelling the lease, go after the owner. It’s not as simple as one breach and you’re out, but persistent offenders put themselves and their landlords on the wrong side of strata law.
