Renting Out Your Home for Sundance 2027 Outside Boulder City Limits: County Rules and the Nov. 1 Deadline
QUICK ANSWER
Homeowners outside Boulder city limits, in unincorporated Boulder County, face a separate set of rules if they want to rent out their property for Sundance 2027. Boulder County requires a short-term rental license valid for two years, and has set November 1, 2026 as its recommended application deadline for anyone who wants approval in time for the festival. This is a different process from the City of Boulder’s festival lodging rental license, and it applies to areas outside Boulder, Longmont, Louisville, Lafayette, Lyons, Jamestown, Nederland, or Superior city limits.

City versus county: which rules apply to you
Boulder County and the City of Boulder are two different licensing authorities, and the festival’s footprint pulls in visitors well beyond the city line. If your property sits in an unincorporated area, meaning it is not within Boulder, Longmont, Louisville, Lafayette, Lyons, Jamestown, Nederland, or Superior city limits, the county’s short-term dwelling and vacation rental license applies rather than any city program. Boulder County’s planning department says short-term rental processing takes several weeks, which is why it recommends the November 1 target for anyone hoping to list a property for the festival window of January 21 to 31, 2027.
Beyond lodging, the same county guidance flags other permits festival-area hosts may need if they are also planning a gathering: a group permit for any event drawing 50 or more people, running longer than eight hours, or spanning 3 or more days with compensation involved, plus separate approval paths for home-based events between 26 and 99 attendees and for farm-based events. Owners planning to combine a rental with an on-site event, such as a gathering for renters or a small party, should check whether that pushes them into the group permit process as well.
Why it matters
We have already covered the city side of this in detail in how Boulder’s Festival Lodging Rental License works, which applies only inside city limits. If you are weighing a county rental against other options, see our rundown of what the official Sundance lodging platform actually lists, since properties booked through that platform still need to carry the correct local license behind the scenes, our post on what lodging may actually cost for Sundance 2027, our note on Airbnb’s host bonus offer for the festival which does not substitute for either jurisdiction’s licensing requirement, and our guide to staying in Denver for Sundance 2027 if you are weighing a county rental against lodging further out.
What we’re watching
We’re watching whether Boulder County extends or adjusts its November 1 deadline as festival demand becomes clearer, whether the county publishes updated processing time estimates as applications pick up, and for any indication the county will extend or waive fees the way some city programs have discussed.
