You receive a noise complaint about ongoing, rowdy parties at a property occupied by teenagers who are renting the property and sometimes lighting fireworks. There have been multiple police calls for service in late hours about the noise disturbing the neighbourhood. Police have been unable to identify who the principal tenant is. As a result, the community is being bothered and police resources impacted. The property owner lives in the same city, but not at that house. Under the noise bylaw, the property owner is culpable for the offense on his property whether they are causing it or not. What would you do to encourage voluntary compliance?
