Neighborhood Block Party Trailer


Thank you for your interest in bringing your neighbors together for positive experiences. The city is committed to its core value of community safety and is proactively taking steps to keep the community safe. Due to physical distancing concerns during the public health crisis and economic impacts to the city organization, the block party trailer program is currently suspended. As the situation develops, we will continue to assess the needs of our community and update program information.

What You Need to Know

All permitting requirements still apply with use of the trailer. You will need a  block party permit  if you are planning to close the street. Type III barricades (required for street closure) are included in the trailer, available at no cost to the host.

Depending on where you plan to use the trailer, you will need to indicate which of the following processes, based on place and use, that you will follow when you reserve the trailer. Reservation of the trailer itself does not initiate these processes for you.   

1. Trailer will be used completely on private property  —  such as private residence, HOA pool or park, apartment parking lot  —  with no impact to public right of way or other space utilized by the public.
Requirement: Letter from the property owner indicating participation/permission for use and a full description of how your event will be isolated from the general public and not impact the public right-of-way in any way. Submit to  [email protected]  and place your name and block party trailer in the subject line of the email to assure receipt. 

2. Trailer will be used in public right-of-way  —  to enhance block parties in neighborhoods on or near city streets, bike paths and sidewalks. Street may or may not be closed but the right-of-way will in some way potentially be impacted.
Requirement:  block party permit  must be completed.

3.  Trailer will be used at or near a public park.
Parks and Recreation has developed a streamlined permit process to encourage neighborhood gatherings. Use of the park for neighborhood gatherings eliminates deposits, allows a gathering to occur outside of the four-hour time blocks used for shelter rentals and authorizes low-level amplified sound. Additionally, activities fitting the neighborhood gathering criteria will not be subject to insurance requirements. 

Be Sure to Find the Right Space

Please note that a total of 50 feet will be needed to allow for ease of delivery and pickup of the trailer.

The trailer 8 feet 6 inches wide, 13 feet 6 inches long and approximately 7 feet tall. The delivery truck and hitch is 22 feet long, and an additional 5 or 6 feet in front of the truck and behind the trailer is needed. A city staff member will drop off and pick up the trailer, and we ask that you find a location that makes it easy to maneuver the trailer. The front or tongue side of the trailer also needs to be clear for delivery and pick-up for the truck that will be towing. The trailer cannot be parked in alleyways.

Finally, during the reservation process it is important to provide the following information:

  1. Describe the precise address and location where you would like the trailer to be delivered. Note: This needs to be a legal parking space and easily accessible for drop-off and pick-up.
  2. How will you ensure that the trailer will be accessible and does not get blocked in by other vehicles at the time of pick-up.


Are you planning to host a neighborhood block party? Great news ... we have additional resources to help you out!

Boulder’s block party trailer has been very popular, and we recognize that demand sometimes outweighs availability. Thanks to feedback from the community, Type III barricades for road closures and Zero Waste bins were highlighted as especially useful resources.

In response to this input, Neighborhood Services has purchased an extra set of Type III barricades that residents with approved block party permits may borrow. These barricades will be stored at Resource Central, 6400 Arapahoe Ave., and block party hosts will receive a voucher with their permit, which they may turn in to borrow the barricades. 

Also, Eco-Cycle, which co-locates with Resource Central, has temporary Zero Waste bins available to rent for a small fee.

The Connection Between Block Parties and Resilient Communities

When Neighborhood Services launched the block party trailer in 2016, the goal was to make it easier for neighbors to gather together and spend some enjoyable time with one another. That remains true, though there is more to it. By spending time with neighbors and strengthening those relationships, communities become more resilient in the face of unexpected shocks and stresses.
