Overview of Noise Rules for Events

The City of Centennial regulates excessive noise and establishes standards to prevent disturbance of the peace during events. Specific numeric decibel limits and quiet-hour definitions are set out in city regulatory materials and the municipal code or in conditions attached to special event permits. If a numeric standard is required for a permit, the permit or event conditions will state how sound is measured and where measurement points are located.

Penalties & Enforcement

Centennial enforces noise rules through local code enforcement and the police department. Official municipal sources do not list a single unified fine table on the publicly linked pages; therefore specific fine amounts are not specified on the cited page and are noted as not specified on the cited page (current as of March 2026). The following summarizes typical enforcement elements and options you should expect.

  • Enforcer: Police Department and Code Enforcement personnel handle complaints and inspections.
  • Complaint pathway: report noise via the city non-emergency line or the code enforcement complaint form.
  • Inspections: officers may measure sound levels and issue warnings, notices to abate, or citations.
  • Fines: monetary amounts are not specified on the cited page; consult the municipal code or the permit conditions for exact figures.
  • Appeals and review: appeals typically follow administrative appeal routes described by the city; specific time limits for appeal are not specified on the cited page.
  • Non-monetary sanctions: orders to cease, abatement notices, permit revocation or event shutdown, and referral to municipal court are possible.
If you receive a noise notice, act promptly to document permits and mitigation steps.

Applications & Forms

Special events generally require a Special Event Permit; the city publishes the permit application and instructions on its events or permitting pages. Fees, submission methods, and deadlines are set on the permit application or in the event permitting guidance; if a fee or deadline is not stated on the public permit page, it is not specified on the cited page.

Common Violations and Typical Outcomes

  • Exceeding permitted sound levels at property lines — possible warning, notice to abate, or citation.
  • Failure to obtain a required special event permit — fines or permit denial.
  • Uncontrolled amplified music after quiet hours — order to stop and possible fines.

How to Comply and Practical Steps

  • Plan early: apply for a Special Event Permit well before the event date and include sound mitigation plans.
  • Document: keep permits, sound equipment specs, and calibration certificates for decibel meters.
  • Mitigate: use directional speakers, sound limits, and time restrictions to meet quiet hours.
  • Report issues: neighbors should report ongoing violations to the city non-emergency line or code enforcement.
