Weld County, CO Special Events & Permits: Street Fair Rules (2026)

Weld County Code Division 18 governs LIMITED EVENTS, defined as a gathering of more than 30 paying or ticketed members of the public in all zone districts except the R (Residential) and E (Estate) zones. Section 23-4-1280 exempts gatherings at already-approved venues with proper zoning, such as churches, restaurants, breweries, wineries, and fairgrounds, if attendance stays within 30 people of the venue's seating capacity. Where a permit is required, § 23-4-1290 caps each event at three consecutive days, limits a property to one event per calendar month and four per calendar year, and requires the organizer to attempt contact with neighbors within 500 feet.

The application and fee must reach the Planning Department at least 30 days before the event under § 23-4-1300, referral agencies get ten days to respond, and the Board of County Commissioners decides at a public hearing after mailed notice and a posted sign. Section 23-4-1330 sets detailed performance standards: potable water and toilets sized to the maximum crowd, a daily trash and waste plan with site restoration within 48 hours of the event ending, two EMTs and one ambulance once attendance exceeds 500 (one more EMT per additional 500), a licensed nurse once attendance exceeds 1,000, lighting of at least five foot-candles if the event runs after dark, no event past midnight, no overnight camping, and one nine-foot-wide parking space for every four attendees.
