Being a Good Neighbor

Expand each of the items below to find details about City and County of Denver guidelines that support being a good neighbor to residents and businesses impacted by your event, providing an accessible experience for all attendees, and creating a more environmentally sustainable event.

Don't forget to refer to the event application timeline to make sure you're meeting all critical deadlines.

Amplified Sound Limits (60 days prior to event)

Stage at the 420 Festival Music DEADLINE: 60 days prior to event

Review the Denver Special Events Noise Fact Sheet to learn about permissible noise levels and how to manage and monitor them during your event.

If your event will include any type of amplified sound (e.g., live music, DJs, speakers, airhorns, musical instruments, generators, etc.), it is critical that you understand and comply with the Denver Noise Ordinance. Noise Ordinance citations can result in fines up to $5,000 per day.

The Denver Department of Public Health and Environment (DDPHE) requires all event applicants to complete and upload the Noise Ordinance Requirements Worksheet(PDF, 416KB)  to their OSE application, regardless of the event’s use of amplified sound and/or mechanical equipment. The worksheet information determines if the event qualifies for a festival exemption which allows for increased noise levels.

If your event will feature amplified sound, you will need to complete the Electronic Communications Agreement form(PDF, 639KB) and contact DDPHE at or 60 days prior to your event date.

Community Notifications (45 days prior to event)

Event organizers are required to notify the residents and business that will be impacted by their event. Informing community members about event hours, road closures, parking restrictions, amplified sound, etc. is important so they can plan appropriately.

At a minimum, you must follow the steps below in preparing and distributing your community notifications.

1.  Create a notification flyer that includes the content and follows the format of OSE’s Sample Notification(PDF, 153KB). Keep it simple and use this template(DOCX, 46KB) to create a notification flyer for your event and then save it as a pdf.

2.  Upload your notification flyer to your OSE application for review, 60 days prior to your event.

3.  Once the notification is approved, distribute it by email a minimum of 45 days before and then again, one week before the event to the following. Copy on all notification emails.

  • Registered Neighborhood Organizations (RNOs) and Business Improvement Districts (BIDs) that will be impacted by your event. Go to to find a map, list and contact information for Denver RNOs and BIDs.
  • City Council office(s) that represent the district(s) impacted by your event. Find the City Council district map and contact information at
  • Denver Police Department District(s) that serve the communities impacted by your event. Find DPD district contact information on the Denver Police Stations webpage.

4.  If your event includes road closures and/or is expecting more than 5,000 attendees, hand-deliver notification flyers to impacted residences, businesses and community centers (e.g., churches, schools, etc.) next to and extending one city block from all road closures and event perimeter. 

Ensuring Accessibility (at least three business days notice)

Accessibility sign at city building entrance DEADLINE: Disability related accommodation requests: at least three business days notice

Events in parks and the public right-of-way must be accessible to everyone, including event attendees and passersby who need to get around your event. Review the ADA Events Planning Checklist for important information and guidance.

If you need a sign language interpreter or Communication Access Realtime Translation (CART) services for your event, contact with at least a three business days notice.
