Summary
Kansas City caps indoor sound at bars and clubs at 85 dB(A) where customers sit, unless the venue posts a hearing-damage warning sign.
No person shall operate, play or permit the operation or playing of any radio, television, music player, drum, musical instrument, sound amplifier or similar device which produces, reproduces or amplifies sound at a sound level greater than 85 db(A) as read by the slow response on a sound level meter at any point that is normally occupied by a customer in any place of public entertainment with a seating capacity of less than 500 persons, unless a conspicuous and legible sign is located outside such place... stating: "WARNING: SOUND LEVELS WITHIN MAY CAUSE PERMANENT HEARING IMPAIRMENT."
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 139 | Zoning and Development Code: Supplement 38).
Full Breakdown
Under City Code § 46-5(8), any place of public entertainment seating fewer than 500 people cannot let a radio, sound amplifier, DJ rig, or live instrument hit more than 85 dB(A), slow response, measured at any customer-occupied spot inside. The cap disappears only if the venue posts a conspicuous sign at its public entrances warning that sound levels inside may cause permanent hearing impairment. The health director's general noise code (§ 46-4) still applies at the property line regardless of the interior reading or the sign.
Violations & Fines
Health department noise control officers cite under Chapter 46; first offense is a $100 administrative citation, with repeat violations within 12 months rising to $300, $500, then $500-$1,000 per day, or referral for court penalties up to 180 days in jail on a fourth-plus offense.
