NYC Noise: 2010 – 2017, increasing probability your noise was not found

Number of service requests to NYC’s 311 from 2004 to 2017: 26.99 million
Increasing probability noise not found, 2004 to 2017

When you call in a noise complaint, there is a probability that the city agency handling the complaint could not find it. Whatever the reason, when you have a high proportion of ‘not found’s, time and money is being wasted, starting with the person calling in the complaint, the person at 311 taking the complaint (if it is over the phone), and various people in various agencies who end up actually processing them. There could be innocuous reasons – maybe the person or entity making the noise has moved on. Or, they have a permit to make noise and it is, therefore, not a violation. Or, there could be less innocuous reasons, including corruption.  Or, the complaint intake design is flawed and 311 is taking complaints for things the city or the agency does not have a remedy or the will to remedy, or both.

The ‘not found’ notations:
