Arnie – It’s worth noting that in order for the Police, Local Council, or even your Committee to take any action about a noise complaint, it needs to be reasonably satisfied that a Breach of a relevant Law (incl. a By-Law) is occurring, and in the absence of any of the above actually hearing it, it’s incumbent upon the complainant to substantiate or otherwise prove their claims with recordings or even a log of dates and times.
The above is in place to prevent frivolous and vexatious complaints.
So your Committee should perhaps do nothing until such time as the Owner concerned substantiates their complaint, or if it wants to be proactive, invest $50 in a digital voice recorder and ask the complainant to set it up in his Unit.
