Hosting a Party or Pop-Up in Unincorporated Boulder County During Sundance 2027? Here’s the Permit Rundown
QUICK ANSWER
Confirmed by Boulder County’s own Sundance 2027 resource guide: hosting a party, watch party, pop-up, or any other gathering on property in unincorporated Boulder County during the festival can trigger permit requirements separate from the county’s short-term rental license. Depending on size and purpose, hosts may need a Group Gathering Permit, a Farm Event or Home Event authorization, a building permit for tents or temporary structures, a liquor permit, or a Retail Food License. These rules apply only outside the City of Boulder and its incorporated neighbors, which have their own separate process.

The county’s permit rundown for hosts
| Requirement | Status |
|---|---|
| Group Gathering Permit: events over 8 hours in a day, 3+ consecutive days, 50 or more attendees, or where the host is paid | Confirmed |
| Farm Events: 26 to 150 attendees on a commercial farm, majority local ingredients required; over 99 needs Zoning Administrator authorization | Confirmed |
| Home Events: 26 to 99 attendees at a residence for paid entertainment or product sales | Confirmed |
| Tents, stages, or temporary structures: building permit, 8-12 week review after a complete application | Confirmed |
| Retail Food License for selling or serving food publicly: applications due by September 2026 | Reported, not yet confirmed |
Boulder County’s Community Planning and Permitting department published this guide specifically for the festival window of January 21 to 31, 2027, and it applies only in unincorporated parts of the county, not inside Boulder, Longmont, Louisville, Lafayette, Erie, Ward, Nederland, or Superior, each of which has its own separate requirements. The county lists two liquor options: a Special Event Liquor Permit for a registered nonprofit raising funds at its own event, and a Sales Room Liquor Permit for breweries, wineries, or distilleries selling through the state’s Liquor Enforcement Division. On food, the county says a Retail Food License is required whenever food is sold to the public, provided at a ticketed event, or offered at any event open to the public, and it is flagging that applications need to be in by September 2026, with high application volume expected and incomplete or late applications at risk of not being approved in time. We list that deadline as reported rather than fully confirmed because the county’s page gives the month but not an exact day, and because that window is closing or may have already closed by the time a host reads this. The county separately reminds hosts that its local minimum wage applies to unincorporated Boulder County, including out-of-area businesses whose workers put in four or more hours there in a week, and that code compliance covers unauthorized rentals, unpermitted structures or gatherings, illegal alcohol sales, and noise complaints.
Why it matters
This is a different track than simply renting out a home, which we covered in our guide to Boulder County’s short-term rental rules and the Nov. 1 deadline. That post touches on event permits briefly; this one is for anyone actually hosting people on county land, whether that’s a farm dinner, a fundraiser, or a backyard watch party. It is also a useful contrast to the City of Boulder’s own festival operations rules, since the two jurisdictions run separate systems with different permits and contacts, and to becoming an Official Friend of Sundance 2027, which is a marketing program rather than a regulatory one.
What we’re watching
We’re watching whether Boulder County publishes a firm Retail Food License deadline given the high volume it is anticipating, and whether the Farm Event and Home Event attendee caps hold as festival planning firms up closer to January.
