Noblesville, IN Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Noblesville's Code of Ordinances splits its noise rules into two regimes. Sections 93.20 through 93.24 apply only 'within the boundaries of the properties described in the legal description provided in Exhibit A of Ordinance 40-5-03,' a defined area rather than the whole city. Within that area, § 93.22(B) sets a blanket 75 dB/A ceiling for more than two minutes an hour measured a half-mile from the source, and § 93.22(C) adds a stricter nighttime rule aimed at amplified sound: it is unlawful to generate or permit sound from electronic amplification above 25 dB/A over the ambient noise level for more than two minutes an hour at the property line, between 11:00 p.m. and 9:00 a.m.

Sunday evening through Friday morning, and between 11:30 p.m. and 9:00 a.m. Friday evening through Sunday morning, giving weekend events a half-hour later curfew. Section 93.23 makes any violation of this subchapter an infraction enforced by a sworn Police Department officer, or by a special police officer on Noblesville Schools property, with citations returnable to Noblesville City Court. Fines escalate with repeat offenses within a two-year window: up to $250 for a first offense, $500 for a second, $1,000 for a third, and $2,500 for a fourth or later offense. A court may suspend a fine if the violation resulted from natural causes or circumstances beyond the defendant's control.
