Understanding Short-Term Rentals in Summit County, Colorado

What Buyers and Owners Need to Know:

Owning a mountain property in Summit County, Colorado, is a dream for many. Whether it's a ski-in/ski-out condominium in Keystone, a townhome in Breckenridge, or a mountain retreat overlooking Lake Dillon, the opportunity to enjoy the Colorado lifestyle while generating rental income can be especially appealing.  But if you're considering purchasing a property to use as a short-term rental (STR), there's something important to understand: Not all properties in Summit County have the same rental opportunities, and the rules can change significantly depending on where a property is located.

In recent years, short-term rentals (any property rented for fewer than 30 consecutive days) have become a major topic throughout Summit County. Local governments have introduced licensing requirements, rental restrictions, and neighborhood-specific regulations to balance tourism, residential housing, and the needs of the local workforce. Understanding these rules before purchasing or selling can make a significant difference in your real estate decisions. Owning a property in a popular vacation area doesn't automatically mean it can be legally rented on a short-term basis.

Different Towns, Different Rules

One of the most common misconceptions among buyers is that Summit County has one set of short-term rental regulations. In reality, each incorporated town establishes its own requirements, while unincorporated areas fall under Summit County's regulations. Here is a general overview of the current regulatory landscape.

Keystone

Keystone is particularly attractive to buyers interested in short-term rental opportunities. Since becoming an incorporated town, Keystone has administered its own STR licensing program. As of October 2026, the town does not have a numerical cap on STR licenses, although licensing, taxes, safety requirements, and HOA restrictions still apply. This distinction is particularly important when comparing resort-area condominiums with properties in nearby residential neighborhoods.

Breckenridge

Breckenridge has established four short-term rental zones with different licensing limits. Certain resort-oriented areas have different restrictions than traditional residential neighborhoods. Some areas have waiting lists for new licenses.

Because licenses generally do not transfer when a property sells, buyers should not assume they can continue the previous owner's rental operations.

Frisco

Frisco limits STR licenses to a percentage of its residential housing inventory, currently 25%. A waiting list is in place for new licenses. As of the town's October 13, 2026 Council discussion, there were approximately 924 active licenses and an estimated nine-month wait for applicants. The Town Council is also evaluating changes to how eligible housing inventory is calculated.

Silverthorne

Silverthorne has different rental caps depending on the neighborhood. Most residential areas are subject to a 10% cap, while the Town Core and Riverfront areas have a 50% cap. Short-term rentals are not permitted in deed-restricted neighborhoods.

These distinctions can create very different rental opportunities within the same town.

Dillon

Dillon requires short-term rental licensing and compliance with its operating regulations. Buyers should pay particular attention to whether a property is actually within Dillon's town limits. A Dillon mailing address doesn't necessarily mean a property is regulated by the Town of Dillon. For example, Dillon Valley is outside the incorporated town and falls under Summit County jurisdiction.
