Outdoor amplified music in Louisville is regulated by a combination of APCD Regulation 5.11 decibel limits and LMCO Chapter 99 nuisance noise rules. Bars, restaurants, and venues along Bardstown Road, NuLu, Waterfront Park, and Fourth Street Live generally must cease amplified outdoor music by 11 PM or midnight, depending on permit conditions.
Louisville treats outdoor amplified music as a regulated sound source. At a residential property line, amplified music must not exceed roughly 55 dBA during daytime and 50 dBA at night. Establishments located in designated entertainment districts such as Fourth Street Live, NuLu, Bardstown Road, and parts of the Highlands often operate under special event permits or conditional use permits that specify outdoor music cutoff times, typically 11 PM on weeknights and midnight on Friday and Saturday. Waterfront Park concerts, the Kentucky Derby Festival, Forecastle, and similar major events obtain dedicated sound permits that temporarily relax the numeric limits. Private parties and residential gatherings do not require permits but still must comply with the nighttime 50 dBA limit and Chapter 99 prohibitions on plainly-audible amplified music across a property line after 10 PM. Repeat violations can result in business license conditions, CUP revocation, and APCD civil penalties. Derby week receives some practical enforcement flexibility but not a legal exemption.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Louisville code enforcement directly for current fines, enforcement procedures, and hearing options.
