Some years ago, my building underwent renovations that extended beyond the expected finish date (surprise!) and everyone in the building looked at scaffolding instead of a harbour view throughout the summer. My tenants complained and demanded compensation and we enlisted the help of our managing agent to agree on an appropriate amount, which I paid.
In hindsight, I should have turned to the Owners’ Corporation and asked them to stump up. The renovations caused a flood in one of the apartments and the affected owner demanded new carpet (and got it). But that was before I started tuning in to FlatChat and learned sooo much more. If this happened again, I would first approach the OC and if they said “no” I would wait for the tenants to initiate mediation.
I agree with Jimmy that your tenants may be serial complainers and if you give compensation (whether paid by you or the person or persons responsible for the noise) you may unleash a hungry beast.
