Arvada, CO Special Events & Permits: Block Party Permits (2026)

The code does not use the phrase block party, but Section 3-1-4-8, Special Events, is the provision that governs one: closing a residential street for a neighborhood gathering falls squarely under trigger 4 of Subsection B, involving traffic control, which by itself requires a Temporary Use Special Event Permit regardless of attendance. The same subsection also requires the permit once an event expects more than 100 attendees at any one time, adds amplified music, speech or lighting, or brings in temporary structures other than ordinary canopies and tables.

Subsection C lets a special event permit authorize the closure on private property, including private streets, or on public property such as city parks, park and recreation district land, public street rights-of-way, or property belonging to another political subdivision, as long as that governmental entity consents. Subsection D caps the permit at 14 days unless the Director specifically authorizes a longer run. Subsections E and F add practical requirements scaled to the event: the city can require on-site restroom facilities appropriate to expected attendance, and the organizer must provide adequate waste containers and clear all litter the event generates, including from adjoining public rights-of-way, at no cost to the city.

Subsection G requires every sign used for the event to be listed in the permit application and to comply with the Temporary Sign regulations in Division 6-1-6.
