Corpus Christi, TX Noise Ordinances: Decibel Limits (2026)

Industrial noise in Corpus Christi is governed by Chapter 31 using the same 70 dBA daytime and 60 dBA nighttime thresholds measured at the receiving property. The city has a significant industrial base including the Port of Corpus Christi (the largest US crude oil export port), multiple refineries, and petrochemical plants along the ship channel. These facilities must comply with both city noise ordinance limits and Texas Commission on Environmental Quality (TCEQ) regulations. Section 31-2 lists engine exhaust discharged without a proper muffler as a specific nuisance. Section 31-6 provides exceptions for certain public operations. Industrial facilities operating near residential areas must manage noise to stay below the applicable thresholds at residential property lines. The port area and heavy industrial zones along the ship channel have fewer residential neighbors, but buffer zone compliance is still required. TCEQ handles air quality and environmental noise complaints from industrial facilities through their regional office.
