Oklahoma City's noise ordinance is codified in Municipal Code Chapter 34. Construction in residential zones is restricted between 11 PM and 7 AM.

Oklahoma City regulates noise primarily through Municipal Code Chapter 34 (Noise), which prohibits excessive, unnecessary, or unusual noise that disturbs the public peace, comfort, and welfare. Construction and demolition activity in residential zones is generally not permitted between 11 PM and 7 AM, while non-residential zone construction is restricted between 12 AM and 7 AM. The ordinance establishes maximum permissible sound levels by zoning district under a published table, with separate daytime and nighttime thresholds (nighttime limits are stricter). For amplified sound, it is unlawful to operate a device for sound production, amplification, or reproduction on public property or a public right-of-way so as to be plainly audible 50 feet or more from the source without a permit. Specific use categories carry their own limits; for example, car wash operations are limited to 70 dB(A) at the property line during 7 AM-10 PM and 55 dB(A) during 10 PM-7 AM. Animal noise that is frequent or prolonged is also prohibited under the chapter, with limited exceptions for public zoos and police service animals. Motor vehicle noise, including modified or defective exhaust systems and unnecessary engine braking, is regulated separately. Enforcement is handled by the Oklahoma City Police Department and Code Enforcement, and violations are prosecuted in Municipal Court.
Violations of Chapter 34 are typically charged as municipal misdemeanors prosecuted in Oklahoma City Municipal Court. Fines vary by offense type and may increase for repeat violations. Officers can issue citations based on the plainly-audible standard or by measured decibel readings. Ongoing or commercial violations may result in additional civil enforcement and permit consequences.
