Full Breakdown

80 carries Tier 1 noise conditions automatically. m. 080(A)(13), and the permittee must keep noise from being unreasonably loud or disturbing within 50 feet of the premises perimeter in all directions, the same 50-foot standard is repeated as condition 22. New entertainment permit applicants must submit an acoustical study from a certified acoustical engineer showing the venue meets the Title 7 noise ordinance, under condition 23; a venue that held a permit within the past 12 months, or that used documented sound-mitigation construction, can request a waiver of that study under condition 24. m. , and 'all noise must be contained within the premises' with no sound audible outside the building at all.

Violations & Fines

Noise that's unreasonably loud within 50 feet of a permitted establishment, or amplified sound run outside the § 5.80.080(A)(13) hours, is a Tier 1 violation the Chief of Police can escalate to Tier 2 or Tier 3 restrictions. Violating Tier 3 conditions is a straight revocation of the entertainment permit under § 5.80.130(A), and a violation of Chapter 5.80 generally is charged as an infraction or misdemeanor.

Frequently Asked Questions

How loud can a Riverside bar's outdoor music be?
Riverside doesn't set a decibel number for Tier 1 venues, § 5.80.080(A)(22) instead bars noise that is 'unreasonably loud or disturbing in light of the facts and circumstances then prevailing' within 50 feet of the premises, and outdoor amplified sound is only allowed during set daytime and evening hours.
What happens after repeated noise complaints against a Riverside nightclub?
Three or more qualifying noise complaints within 30 days move the venue into Tier 2 under § 5.80.080(B)(1): doors and windows must stay closed, an acoustical study is required, and entertainment of any kind is barred after 1:00 a.m., with outdoor entertainment cut off at 10:00 p.m.
Can Riverside revoke a bar's entertainment permit over noise?
Yes. A venue that doesn't fix its noise problems escalates to Tier 3 under § 5.80.080(C), which bars all outdoor entertainment and requires that no noise be audible outside the building; violating Tier 3 conditions is a revocation of the entertainment permit under § 5.80.130(A).
