Quiet hours in Hamilton County, IN — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Hamilton County has no countywide quiet-hours ordinance; each city regulates noise. In Carmel, residential districts allow up to 55 dB(A) from 8 AM to 10 PM and 50 dB(A from 10 PM to 8 AM, measured 50 feet from the source.
Almost everyone in Hamilton County lives in an incorporated city, so noise is a CITY matter under Indiana Code 36-8-2-8, not county code. Carmel City Code Sec. 6-158 sets a decibel chart by zoning district: residential zones (S-1, S-2, R-1 through R-5) allow 55 dB(A) from 8:00 a.m. to 10:00 p.m. and 50 dB(A) from 10:00 p.m. to 8:00 a.m., measured at least 50 feet from the source. Sound audible 50 feet or more from its source can also violate the code. Fishers uses device-based limits instead of fixed quiet hours. Noblesville and Westfield have their own noise codes.
In Carmel, a violation is an infraction with fines up to $250 first offense, rising to $2,500 for fourth and later offenses. Carmel City Court has jurisdiction.
