Amplified music rules in Jefferson County, KY — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Louisville Metro regulates amplified sound under LMCO Chapter 99. Outdoor amplified events on public property require a special event permit. Waterfront Park, NuLu, and the Highlands entertainment strips have specific sound conditions tied to ABC licenses.
Amplified music in Louisville Metro is governed primarily by LMCO Chapter 99 (Noise Control), which prohibits sound that exceeds decibel thresholds measured at the receiving property line and bans plainly audible amplified music across a property line during nighttime hours. Outdoor events on public property — Waterfront Park, Jefferson Square, the Belvedere — require a Louisville Metro Special Events permit through Metro Parks or Public Works, with sound conditions attached. Bar-district venues (Baxter Avenue, Bardstown Road, NuLu's East Market, Fourth Street Live!) operate under ABC (Kentucky Alcoholic Beverage Control) licenses that incorporate noise conditions. Residential quiet hours under Ch. 99 are generally 11 PM to 7 AM. The Kentucky Derby Festival (Thunder Over Louisville, Pegasus Parade) and Forecastle Festival operate under waivered permits.
Civil noise citation under LMCO §99.06: $50 to $500 per occurrence. Unpermitted outdoor amplification: event shutdown plus citation. Repeat bar-district violations can trigger ABC review and special-use permit revocation.
