The Sundance Film Festival moves to Boulder in January 2027. The math for ADU owners is hard to ignore.
Quick Summary
- The Sundance Film Festival officially relocates to Boulder for its inaugural Colorado edition, January 21–31, 2027.
- Boulder has 2,900 hotel rooms. The festival draws roughly 90,000 attendees. That gap is your opportunity.
- In Park City, short-term rental rates ran 3x–5x higher than normal during festival windows. Boulder’s supply crunch is worse.
- A new Festival Lodging Rental License ($190) lets you legally rent your ADU for up to 29 days per year during city-approved events, even if it’s already on a long-term lease.
- Colorado’s HB24-1152, effective June 2025, removed most of the barriers Boulder homeowners used to face when building an ADU.
- If you want to be ready for the 2027 festival, the time to break ground is now.
The timing here is unusual. Big economic shifts don’t usually come with a clear countdown clock. But this one does: January 21, 2027. That’s when the Sundance Film Festival opens its first-ever Boulder edition, and the city’s lodging math will flip overnight.
Boulder has roughly 2,900 hotel rooms. Park City — a town a fraction of Boulder’s size — had about 4,000 when it hosted the festival. Sundance expects to bring approximately 90,000 attendees to Colorado each year under a 10-year deal projected to generate over $2 billion in economic impact for the state. You don’t need a finance background to see the problem. There simply won’t be enough beds.
That’s exactly where a backyard ADU comes in.
⏳ Order Deadline: May 31, 2026
Order by May 31 and Olerra can have your Flex-Flat built, installed, and rental-ready before January 21, 2027. After that date, we can’t guarantee delivery in time for Sundance.
What Park City Teaches Us
Park City spent years as a living proof-of-concept for what a global film festival does to a local rental market. The short version: it’s extreme. During the festival’s 10-day window, nightly rates for residential properties regularly ran 300%–500% above typical winter rates. Not occasionally. Every single year.
By 2025, Park City’s average nightly rate during Sundance was pushing $4,300 for properties that normally rented for under $900. Some homeowners in the “Main Street” corridor covered a full year’s mortgage in 11 days. And that was in a town that had more hotel rooms and a smaller demand-to-supply gap than Boulder will.
Small units performed especially well. Studios and one-bedrooms actually had higher occupancy rates than larger homes during the festival — 60% vs. 53–54% — because the core demand driver isn’t corporate retreat groups. It’s individual industry professionals: filmmakers, journalists, talent agency staff, and tech crew who want something private, reliable, and close to the action. A backyard ADU is exactly what they’re looking for.
| Unit Type | Park City Baseline ADR | Sundance Festival Premium | Occupancy Rate |
|---|---|---|---|
| Studio | $330/night | $800–$1,200/night | 60% |
| 1-Bedroom | $369/night | $1,000–$1,500/night | 56% |
| 5+ Bedroom Home | $900+/night | $3,000–$6,000/night | 53% |
Boulder’s Numbers Are More Extreme
Here’s the thing about using Park City as a benchmark: Boulder’s supply constraint is actually worse. Park City had around 4,000 hotel rooms. Boulder has 2,900. That’s 27.5% fewer rooms to absorb the same wave of attendees. Festival-goers who can’t find a hotel don’t just skip the trip. They find private housing, and they pay what it takes.
Boulder’s current rental baseline — which is what any festival premium gets calculated on top of — is already strong. For 2025–2026:
| Unit Size | Avg Monthly Rent | Baseline Daily Rate | Projected Sundance Nightly Rate (2027) |
|---|---|---|---|
| Studio (~400 sq ft) | $1,636/mo | ~$55/night | $220–$330/night |
| 1-Bedroom (~600 sq ft) | $1,953/mo | ~$68/night | $272–$408/night |
| 2-Bedroom (~800 sq ft) | $2,618/mo | ~$87/night | $348–$522/night |
And those are conservative estimates. For ADUs within half a mile of Pearl Street or the CU campus, projections go significantly higher. In Park City, “epicenter” units routinely hit 10x their baseline. Downtown Boulder equivalents could see $600–$1,000 per night for an 800 sq ft unit during the festival window.
“For many Park City homeowners, the revenue from these two weeks was enough to cover an entire year’s mortgage payments.”

Where Your ADU Sits Matters
Unlike Park City’s single Main Street corridor, Sundance in Boulder activates the whole city. The Boulder Theater downtown, Macky Auditorium and Muenzinger Auditorium at CU, and a network of historic neighborhoods all serve as key hubs. That’s actually good news for homeowners across a wider geographic range.
Downtown & Pearl Street Mall
Primary cultural and social hub. Walkability is the top priority for high-net-worth guests.
$600–$1,000/night (2027)
University Hill & CU Campus
Major screening venue cluster. Strong pull for filmmakers and industry professionals.
$400–$750/night (2027)
Whittier & Mapleton Hill
Historic character and quiet streets within walking distance of downtown. Preferred by talent seeking retreat.
$500–$800/night (2027)
The Legal Side Got a Lot Simpler
Two big regulatory changes happened in quick succession, and together they cleared most of the obstacles Boulder homeowners used to face.
Colorado HB24-1152, effective June 30, 2025, now requires most single-family zoned lots to allow at least one ADU by right. Local governments have to approve ADU applications through an administrative process, without public hearings. Owner-occupancy requirements are gone. In many cases, so are the extra parking requirements. Boulder fought this kind of flexibility for years. The state overruled it.
Then Boulder introduced the Festival Lodging Rental License, a $190 permit specifically created for the Sundance era. It lets you rent your property for up to 29 days per year during city-approved events. It bypasses the standard short-term rental primary residence rule, so investment properties and second homes can participate. And if your ADU is already on a long-term lease, it can still join the festival window. Applications opened in December 2025 and process in about one to two weeks.
The permitting sequence for an ADU itself runs a bit longer: building permits generally take two to six months, and you’ll want a life safety inspection scheduled at least 60 days before your target rental window. If January 2027 is your goal, starting now isn’t early. It’s right on time.
The Long View: It’s Not Just About Two Weeks in January
The festival premium is real, but an ADU’s value goes well beyond it. On a $300,000 construction investment for a detached unit, the 10-year picture looks like this:
| Income Source | Estimated Annual Return |
|---|---|
| Property appreciation (immediate equity gain) | $210,000–$360,000 added at build |
| Long-term rental income | ~$24,000/year |
| Sundance festival window (11 days) | ~$8,000+/year |
Research on Boulder’s market suggests that a newly built ADU adds roughly 100 times its monthly rental value to the home’s resale price. In a market where a studio rents for $1,636/month, that’s $163,600 in added equity. In high-demand neighborhoods near Pearl Street, where units regularly rent for $3,300+/month, the math gets even better.
Over 10 years, cumulative net revenue after maintenance and taxes on a $300,000 ADU can reach $300,000 — effectively paying for itself while the underlying property keeps appreciating. The cash-on-cash return in a strong Boulder rental environment runs 10–15% annually.
And yes, the 10-day festival window is the headline. But the ADU works for you the other 355 days too.

Frequently Asked Questions
Do I need to live on my property to rent my ADU during Sundance?
Not anymore. Colorado’s HB24-1152, which took effect June 30, 2025, removed owner-occupancy requirements for ADUs. Boulder’s Festival Lodging Rental License reinforces this by explicitly allowing investment properties and second homes to participate in the festival rental window. You apply for the license, pass a life safety inspection, and you’re eligible.
My ADU is already rented long-term. Can I still use it for Sundance?
Yes. The Festival Lodging Rental License specifically permits ADUs that already hold a long-term rental license to participate in the festival window. You’d need to coordinate with your current tenant, but the city’s framework allows for it. Worth reviewing the terms of your existing lease agreement before applying.
How realistic are the $300–$500/night projections? Isn’t that speculative?
It’s an extrapolation, yes, but it’s grounded in real market data from Park City across five festival years (2021–2025). Park City saw 3x–5x multipliers on baseline daily rates during the festival window, even for small units. Boulder’s baseline is slightly higher, and its hotel shortage is 27.5% more severe. The conservative scenario (3x multiplier) still lands studio ADUs in the $165/night range. The realistic scenario for well-located units in downtown Boulder pushes significantly higher. No projection is a guarantee, but this isn’t guesswork either.
How long does the ADU permitting and build process take in Boulder?
For a detached ADU, expect two to six months for building permit approval, followed by the construction timeline. A modular ADU like Olerra’s Flex Flat compresses that schedule considerably compared to traditional stick-built construction. The Festival Lodging Rental License itself takes one to two weeks to process once submitted, but you’ll also need a life safety inspection scheduled at least 60 days before your rental window. If January 2027 is your target, starting the process in spring or summer 2026 gives you a workable runway.
What makes a Sundance-ready ADU different from a standard rental unit?
Festival guests, especially industry professionals, have specific expectations: fast, reliable internet (ideally a mesh network capable of handling 4K content screening and video calls), winter-ready outdoor space, quality bedding and finishes, and proximity to venues. Units within half a mile of Pearl Street or the CU campus command the highest rates. Beyond location, the biggest differentiators are connectivity, presentation, and professional management. Many owners in Park City worked with property management firms at 20–30% of revenue to maintain “festival-grade” standards without handling 24/7 guest communications themselves.
Rate projections and financial estimates are based on historical Park City STR performance data (2021–2025), current Boulder rental market data (2025–2026), and publicly available research on ADU construction costs and ROI in the Boulder metro area. Actual returns will vary based on location, unit quality, pricing strategy, and market conditions. This article is for informational purposes and does not constitute financial or investment advice.
