South Gate FAQ
How do I know if my neighbor is over the limit?
Measurement must be taken at your property line (or the nearest public right-of-way) with a Type-2 sound-level meter set to dBA fast-response, averaged as Leq. Code Enforcement officers carry calibrated meters; you can also document with logged readings from any reputable sound-meter app for an initial complaint.
Does ambient noise count toward the limit?
Yes — Chapter 11.34 standards are 'inclusive of ambient noise.' If background ambient from traffic on Atlantic or Firestone Blvd is already near the standard, even modest added sound from a source can constitute a violation.
What about temporary noise like a backyard party?
Table 11.34-2 sets maximum temporary increases above ambient by duration — the shorter the event, the greater the permitted excess. But sustained noise exceeding these caps, especially after 10 p.m., is a violation.
