Full Breakdown

Chapter 34's noise control code sets maximum sound-level limits for residential, commercial and industrial property across both the City of Lafayette and the unincorporated parish (the code defines "Lafayette" to mean both). Sec. 34-368 lists categories fully exempt from the decibel limits and quiet-hours rules, and item (6) is aircraft operations. That means airport traffic and flights near Lafayette Regional Airport face no sound-level cap under this code. Broussard, Carencro, Duson, Scott, Youngsville and Milton run their own municipal codes and aren't reached by Chapter 34 at all.

Violations & Fines

Aircraft noise itself cannot be cited under Chapter 34: the exemption is absolute. Other noise on airport property, like idling ground equipment unrelated to flight ops, may still fall under Sec. 34-366's decibel limits.
