I’ve never had any issues for that. I’ve always kept the cages on a wall that does not border the neighbouring suite, and though the birds can be heard in the hallway, they don’t tend to scream all day so I have found tenants ignore them for the few times they squawk louder than usual.
A good thing to do is let your neighbours know you have a bird, and to let you know if they hear them And are a bother or check with them after a few days..It shows that you are respectful of their feelings which goes a long way in them being more tolerant....
I have a tenant that has a rainbow lorikeet which tends to be loud, and though neighbours can hear her, once they know what the sound is from, after a few days they don’t notice her anymore . It’s like traffic noise, we tend to adapt to the noise...
I do not know how loud linnies can be but it can’t be any louder than a lorikeet I would think...
