Summit County Short-Term Rental Regulations: 2026 Guide for Buyers
Short-term rental rules in Summit County are not one-size-fits-all. Breckenridge, Frisco, Silverthorne, Dillon, Blue River, Keystone, Copper Mountain, and unincorporated Summit County all operate under different rules, caps, waitlists, and licensing paths. A property with strong rental history does not guarantee you can rent it after closing. Licenses do not transfer. And the mailing address is often the worst possible guide to which rules actually apply.

Quick Answer
Yes, short-term rentals are allowed in many parts of Summit County. But the rules depend heavily on the exact jurisdiction, and one of the biggest mistakes I see is buyers assuming the rules are the same everywhere.
The real question is not just "Can I Airbnb this property?" It's what jurisdiction the property is actually in, whether a new buyer can obtain a license after closing, whether the HOA allows it, and whether the rental strategy still makes sense under today's rules. That is what this page is for.

I have been helping buyers evaluate STR properties in Summit County since 2017. The same mistakes come up constantly. Someone falls in love with a property, the listing mentions great rental history, they assume they can continue renting after closing, and then they find out the license does not transfer, or the basin is over cap, or the HOA prohibits it, or the mailing address says "Dillon" but the property is actually in unincorporated Summit County with a completely different set of rules.

Where Things Stand Right Now
Every jurisdiction in one table. The details for each are below, but this is the 30-second read. Counts based on June 2026 data, the most recent verified figures at publication. Verify before acting.
| Area | System | Current Status | What It Means for a Buyer |
|---|---|---|---|
| Copper Mountain | Summit County / Resort Overlay Zone | No cap. No waitlist. | Cleanest STR path in the county. HOA and building rules are the real due diligence. |
| Keystone | Town licensing (since Sept 2024) | No cap. No waitlist. No night limit. | Most open licensing path in Summit County right now. Built as a resort. STRs are the expected use. |
| Dillon | Town licensing | No cap. No waitlist. | Usually straightforward once you confirm it is actually inside Town of Dillon and not Dillon Valley. |
| Blue River | Town registration | Moratorium through Dec 31, 2026 | No new licenses until moratorium lifts. Ordinance being rewritten. Long-term rentals (30+ days) still legal. |
| Silverthorne | Three-zone system | Zone-dependent Zone 1: 23 of 215 available Zone 2: 299 of 526 available Zone 3: No licenses |
Zone 2 is the clear opportunity. Zone 1 is getting tight. Zone 3 is deed-restricted workforce housing. No licenses, period. |
| Frisco | 25% housing stock cap | Cap reached. Waitlist active. 83 on waitlist (April 2026) |
Estimated 12 to 14 months. A plannable timeline if you go in knowing it. Strong market worth the wait for the right buyer. |
| Breckenridge | Four-zone system | Zone-dependent Resort Zone: open Zone 1: open Zone 2: waitlist Zone 3: 8 to 15+ yr wait |
Zone is everything. Resort Zone and Zone 1 carry a premium. Zone 3 buyers are waiting a very long time. That is not a typo. |
| Unincorporated Summit County | Basin caps + overlay zones | Basin-dependent. All four NOZ basins capped or over cap. Resort Overlay (Copper, Tiger Run): no cap. |
Most complex rules in the county. 35-booking/year limit in residential areas. Active waitlists. County's published information is also unreliable. Call before acting on anything you read on their site. |
| Montezuma | Town prohibition | STRs prohibited | Not the right purchase if STR income is part of the plan. Full stop. |
The Single Most Important Thing: Confirm Jurisdiction Before You Assume Anything
This catches buyers more often than you'd think. A property with a Breckenridge address might be in Blue River or unincorporated Summit County. A Dillon address might be Dillon Valley, which is unincorporated Summit County with completely different rules. A Silverthorne address might be Wildernest, same problem. The listing description will not flag this. The mailing address will not tell you.
Before relying on any STR assumption, confirm which of these actually controls the property:
- Town of Breckenridge
- Town of Frisco
- Town of Silverthorne
- Town of Dillon
- Town of Blue River
- Town of Keystone
- Town of Montezuma
- Unincorporated Summit County
- An HOA with its own rental rules layered on top of all of the above
Use the Summit County GIS Parcel Query Tool. Enter the address and check the Jurisdiction field. If it says a town, that town's rules apply. If it says unincorporated Summit County, you are in a different world entirely. This takes thirty seconds and can save you from a very expensive mistake.
Already know the jurisdiction? Jump to the section above for that area, or use the navigation links at the top of the page.
Already know the rules? Read the income guide.
Understanding the rules is step one. Step two is figuring out whether the income actually pencils out: what properties realistically earn by bedroom and market, how the money flows, what management costs, and whether it offsets your carrying costs.

STR Due Diligence Checklist
If STR use matters to your purchase, confirm all of these before you write an offer. Not after.
- Confirm actual jurisdiction using the GIS tool. Not the mailing address.
- Confirm whether a new buyer can obtain a license at this property under current rules.
- Verify whether the seller's license transfers. In every Summit County jurisdiction, it does not.
- Review HOA rules: rental minimums, parking, quiet hours, occupancy limits. Some buildings are stricter than the town.
- Confirm whether the property is in a capped area, waitlist area, basin, overlay zone, or resort area.
- Check renewal deadlines. Missing them in some jurisdictions means losing the license entirely.
- Compare the rental plan against personal-use goals, carrying costs, and long-term regulatory risk.
I run through this checklist on every STR-focused purchase before any offer goes in. If you want a second set of eyes on a specific property before you commit to inspections or travel, reach out. 303-907-9129 | TZimmerman@SliferSummit.com
Copper Mountain
Copper Mountain is in unincorporated Summit County but falls entirely within the Resort Overlay Zone. No cap, no waitlist, no night limit. 100% of properties are eligible. Licensing runs through Summit County rather than an incorporated town, which means no town council with the political will to restrict licenses down the road.
What I tell buyers: the due diligence here is not on the licensing. That part is clean. It is on the building. Some Copper Mountain buildings have mandatory rental programs, rental pools, or HOA restrictions that significantly affect how you operate. Read the HOA documents before you fall in love with a unit, not after.

Keystone
Keystone became Colorado's newest town in February 2024 and took over its own STR licensing from Summit County in September 2024. No cap, no waitlist, no night limit. The town was built as a resort from day one, which means none of the neighborhood-versus-vacation-rental friction that pushes other Summit County towns toward restrictions.
What I tell buyers: it is the most straightforward licensing path in the county right now. Confirm HOA rules and any building-specific restrictions before assuming you can self-manage, but the town side of this is about as clean as it gets.

Official source: Town of Keystone STR Licensing
Dillon
Dillon does not cap STR licenses. The path is usually straightforward. The work is in the details.
- Jurisdiction first: properties in Dillon Valley or Summit Cove have a Dillon mailing address but are in unincorporated Summit County with entirely different rules. This catches buyers more often than you'd think. Verify with the GIS tool.
- HOA reality: many Dillon condos have rental rules, quiet hours, and parking constraints that matter as much as the town license.
- Renewal deadline: licenses expire May 31. Renewals not completed by July 1 cannot be renewed, and the owner must cease STR operations immediately.

Blue River
Blue River changed significantly in May 2026. On May 19, the Town paused new STR licenses and renewals through at least December 31, 2026 while it rewrites its ordinance from scratch. No new applications are being accepted.
Before the moratorium, Blue River was a compelling large-home STR market: no cap, no waitlist, strong proximity to Breckenridge, solid group rental demand for four-to-six-bedroom homes. Those property fundamentals have not changed. What changed is the licensing path for new buyers in 2026. Long-term rentals of 30 or more consecutive days remain fully legal.
The mailing address trap applies here too. Many properties with Breckenridge addresses south of town are not inside the Town of Blue River. Verify jurisdiction with the GIS tool before assuming Blue River's rules, including its moratorium, applies.
Full details: Blue River Short-Term Rental Rules Guide, covering what the moratorium means for buyers, who it affects, and what the new ordinance might look like.

Silverthorne
Silverthorne uses a three-zone licensing system. The zone your property is in determines everything.
- Zone 1 (In-town neighborhoods): 215 max, 192 issued, 23 currently available. Getting tight. Verify directly with the town before going under contract.
- Zone 2 (Town Core, Riverfront, Summit Sky Ranch): 526 max, 227 issued, 299 currently available. The clear opportunity right now.
- Zone 3 (Deed-restricted workforce housing): No licenses. If a property is priced well below market, check for a deed restriction.
Wildernest, despite its Silverthorne mailing address, is unincorporated Summit County, not Silverthorne. Different rules entirely.

What I watch for in Silverthorne: zone boundaries and HOA restrictions often matter as much as the license count. Some buildings are stricter than the town, and that's the real limiter.

Frisco
Frisco caps STR licenses at 25% of residential housing stock, approximately 900 licenses. The cap was reached in February 2023. There are currently 83 applicants on the waitlist as of April 2026, with an estimated wait of 12 to 14 months.
Important timing detail: Frisco licenses renew on April 30. If a meaningful batch of holders do not renew that year, it accelerates movement off the waitlist. The pace varies and is worth tracking if you're planning a purchase around it.
What I tell buyers: Frisco is a very good STR market for buyers who go in with a realistic licensing plan. The demand is real, the town is well-run, and the waitlist is a known variable rather than an unknown one. The mistake I see is buyers assuming they can start renting immediately after closing. The key is understanding the timeline before you purchase, not after.

Breckenridge
Breckenridge uses a four-zone STR system, and the zone is the most important thing a buyer can know about any Breckenridge property. The Town Council's map created clear winners and losers, and that shows up in pricing.
- Resort Zone: no cap. Cleanest licensing path. Properties here carry a premium because of it.
- Zone 1: 455 licenses available as of December 2025. Open, but verify before assuming it stays that way.
- Zone 2: at cap with a waitlist.
- Zone 3: 668 over cap as of December 2025. Estimated 8 to 15+ year wait. That is not a typo.
What I tell buyers: some properties with a Breckenridge mailing address are not inside the Town of Breckenridge. They may be in Blue River, unincorporated Summit County, or another jurisdiction. The GIS tool confirms it. The listing description usually does not. Not sure what zone a property is in? I can usually help buyers identify potential STR issues before they spend money on inspections, travel, or due diligence.

Unincorporated Summit County
This is the most complex STR framework in the county and the one most likely to catch buyers off guard. It covers Wildernest, Dillon Valley, Summit Cove, Mesa Cortina, Peak 7, Alpine Breckenridge, Frisco Terrace, and others. Most carry mailing addresses that suggest they follow a town's rules when they do not.
A note on Summit County's published information: the county's STR regulations page shows cap numbers that imply licenses are available in basins where no new applications are being accepted. The waitlist documents are updated once a year while the county issues licenses from those waitlists on a rolling basis throughout the year. The published numbers do not match reality, and there is no single county webpage that reconciles them.
Do not rely on what you read on the county's site before making a purchase decision. Call me first. 303-907-9129 | TZimmerman@SliferSummit.com
The Resort Overlay Zone: No Cap, No Waitlist
Copper Mountain, Tiger Run Resort, SkiWatch, and the 4 O'Clock subdivision fall in the Resort Overlay Zone. No cap, no waitlist, no booking limit. 100% of properties eligible. This is the only immediately accessible STR path in unincorporated Summit County for most buyers.
The Neighborhood Overlay Zone: Caps, Waitlists, 35-Booking Limit
In Neighborhood Overlay areas, owners are limited to 35 bookings per year. That is reservations, not nights. A 7-night minimum and 35 bookings equals up to 245 rental nights. This limit does not exist in any incorporated Summit County town. All four basins are currently at or over cap.
License Caps by Basin (January 2026)
- Lower Blue Basin (Wildernest, Mesa Cortina, Buffalo Mountain, Silver Shekel): 550 cap, 508 active. Waitlist open.
- Upper Blue Basin (Peak 7, Alpine Breckenridge, Quandary Village, McDill Placer): 590 cap, 563 active. Waitlist open. Licenses actively being issued as of early 2026.
- Snake River Basin (Dillon Valley, Summit Cove, Summerwood): 130 cap, 137 active. Over cap. Waitlist open.
- Ten Mile Basin (Frisco Terrace, Evergreen, unincorporated Frisco parcels): 20 cap, 24 active. Over cap. Waitlist active.
Summit County basin locator map. Always verify the specific property jurisdiction before purchasing.
One of the biggest mistakes I see: buyers assume a property follows town rules because the listing says "Silverthorne" or "Dillon." In reality the property is in unincorporated Summit County with basin caps, a 35-booking limit, and a waitlist. The listing will not flag this.
Why are some basins over cap? The caps were set after licenses were already issued. Existing licenses were grandfathered in. The count decreases through attrition when properties sell and licenses do not transfer, or when owners do not renew. The Upper Blue Basin began issuing new licenses to waitlist holders in early 2026. The others are still waiting for attrition to create room.

Montezuma
Short-term rentals are prohibited in the Town of Montezuma. If STR income is part of your plan, Montezuma is not the right purchase. That's not a close call.
Montezuma is right for a specific buyer: someone who wants a genuine backcountry base near Keystone with exceptional access to backcountry skiing, snowmobiling, and high-alpine terrain, and who does not need rental income to make the numbers work. Long-term rentals of 30 or more consecutive days are fully legal.
What This Means for Buyers Right Now
If short-term rental income matters, your best current options are Keystone, Dillon town limits, Copper Mountain in the Resort Overlay Zone, and Silverthorne Zone 2. Frisco is workable if you can absorb a 12 to 14 month wait. Breckenridge works in the Resort Zone and Zone 1. The zone is everything. Blue River is paused. Unincorporated Summit County Neighborhood Overlay basins are a long-horizon play for most buyers right now.

Frequently Asked Questions
Can I short-term rent a property in Summit County?
Yes, in many areas, but the rules depend on the exact jurisdiction, zone, basin, and HOA. Keystone, Dillon, Copper Mountain, and Silverthorne Zone 2 have the clearest paths right now. Frisco has an active 12 to 14 month waitlist. Breckenridge and unincorporated Summit County require careful review. Blue River has a moratorium through at least December 2026. Montezuma prohibits STRs entirely.
Do STR licenses transfer when a property sells?
No. In every Summit County jurisdiction, a buyer must apply for a new license after closing under the rules that exist at the time of purchase. Assume the license does not transfer. You will be right every time.
What is the 35-booking-per-year rule?
In the Neighborhood Overlay Zone of unincorporated Summit County, owners are limited to 35 separate bookings per year, not nights. Many owners respond by setting multi-night minimums to maximize revenue per booking. A 7-night minimum and 35 bookings equals up to 245 rental nights. This limit does not exist in any incorporated Summit County town.
Can an HOA prohibit short-term rentals even if the town allows them?
Yes, though it's less common than people assume. Very few Summit County HOAs restrict STRs outside of deed-restricted affordable housing. Some buildings allow STRs, some limit them, and a small number effectively prohibit them through quiet hour requirements, parking rules, or occupancy caps. HOA review should happen early, not after you have committed money to inspections and due diligence.
Which Summit County areas have the clearest STR licensing path right now?
As of mid-2026: Keystone, Dillon town limits, Copper Mountain Resort Overlay Zone, and Silverthorne Zone 2. These are the markets where a buyer can apply after closing without joining a waitlist or navigating a moratorium.
Why does jurisdiction matter so much?
Because the mailing address on a listing is often the worst possible guide to which STR rules apply. A Dillon address might be Dillon Valley, which is unincorporated Summit County with a capped basin and a waitlist. A Silverthorne address might be Wildernest. Same problem. A Breckenridge address might be Blue River or unincorporated Summit County. Confirm jurisdiction with the Summit County GIS tool before assuming anything.
What is the Blue River moratorium?
On May 19, 2026, the Town of Blue River imposed an emergency moratorium on new STR licenses and renewals through at least December 31, 2026. The Town is rewriting its STR ordinance from scratch. No new applications are being accepted. Existing compliant license holders continue operating. New rules are expected in 2027. Full details: Blue River STR Rules Guide.
Can I trust Summit County's published STR information for unincorporated areas?
Not without verification. The county's regulations page shows cap numbers that imply licenses are available in basins where no new applications are being accepted. Waitlist documents are updated once a year while the county issues licenses on a rolling basis. Call Summit County Community Development directly at 970-668-4186 or email str@summitcountyco.gov, or call me and I'll help you get a current answer. 303-907-9129
Is Summit County still a good place to buy an STR property?
Depends entirely on the property, the jurisdiction, and what you're trying to accomplish. That doesn't mean it's a bad time to buy. It just means you should go in with realistic expectations. Long-term appreciation in Summit County has been the primary wealth driver for most owners here. STR income offsets carrying costs, but it's rarely the whole story. For buyers who understand the licensing landscape and choose accordingly, there are still very good purchases to be made.
