Navigating Summit County Real Estate: A Guide to Short-Term Rental Regulations and Building Permits

Short-Term Rentals: Understanding the Current Landscape

Like many popular mountain towns in Colorado, Summit County and its municipalities have adopted short-term rental (STR) regulations to strike a balance between tourism and preserving community character. As of early 2025, unincorporated Summit County is maintaining waitlists for Type II STR licenses in the Lower Blue and Upper Blue Basins—areas that include neighborhoods like Silverthorne and Wildernest. These caps are part of an effort to limit rental density in primarily residential zones and protect long-term housing stock. The Summit County STR regulations provide detailed maps and updates for those considering STR ownership in these areas.

It’s important to note that each town within the county sets its own rules. For example, the Town of Breckenridge has capped licenses in certain zones but allows unrestricted rentals in resort areas. Frisco, Dillon, and Silverthorne all have their own caps, fees, and license transfer policies. If you’re considering purchasing a property with STR potential, it’s essential to research local regulations early—some areas allow license transfers during a sale, while others require joining a waitlist or starting the process from scratch. Partnering with a local expert can help navigate these rules and avoid costly surprises.

Key Points:

  • License Caps: Each town and basin within Summit County sets its own STR rules and license caps. For example, the Lower Blue Basin is capped at 550 licenses, with 534 currently issued, while the Upper Blue Basin has a cap of 590 but already has 610 licenses in circulation. When the number of active licenses exceeds the cap, no new licenses are issued until it falls below the limit—and there’s no clear timeline for when that will happen. Towns like Breckenridge, Frisco, Dillon, and Silverthorne also maintain their own licensing rules, including zone-based caps, occupancy limits, and transfer restrictions. If you’re buying with STR in mind, make sure to research local policies early.

 

  • Waitlist Implementation: With license numbers nearing or exceeding caps in areas like the Lower and Upper Blue Basins, Summit County has created waitlists to manage new STR applications. Applicants are placed in a queue and considered only as licenses become available—usually through non-renewals or sales. There’s no set timeline for when openings will occur, so planning ahead is essential for buyers interested in short-term renting.

  • Application Process: Before applying for a short-term rental license, property owners must first verify their location using the Summit County Basin Map. The application process varies by area—each town and basin has its own rules, fees, and requirements. To help you navigate these differences, we’ve compiled summaries for each municipality on our website: Short Term Rentals – The Skinner Team

Implications for Buyers and Sellers:

  • Buyers: If you’re considering purchasing a property for short-term rental purposes, ensure it’s located in an area where STR licenses are available or understand the waitlist process. 
  • Sellers: Having an existing STR license can be a valuable asset.

Building Codes and Permits: What You Need to Know

Summer is a popular time for home renovations in Summit County. However, it’s essential to understand which projects require permits to avoid potential legal issues or complications during property sales.

Projects Typically Requiring Permits:

  • Structural Changes: Any alterations to the structure, including additions or significant modifications.
  • Decks and Guard Replacements: Building or replacing decks and guards.
  • Hot Tub Installations: Installing a stand-alone hot tub requires both a building and electrical permit.
  • Window Replacements: Replacing windows, especially if altering the size or structure.
  • Mechanical, Plumbing, and Electrical Work: Installing or modifying systems like HVAC, plumbing, or electrical setups.
  • Septic System Upgrades: Replacing or upgrading a septic system requires a permit and often involves hiring a licensed engineer to ensure the new system complies with current county and environmental standards.

Projects That May Not Require Permits:

  • Minor Repairs: Painting, flooring, or other cosmetic updates.

     

  • Like-for-Like Replacements: Replacing fixtures or appliances without altering the structure or systems.

     

Where to Obtain Permits:

  • Summit County Building Inspection Department: Handles permits for unincorporated areas. Summit County, CO – Official Website

     

  • Town-Specific Departments: For properties within town limits, contact the respective town’s community development or building department.

     

Importance for Buyers and Sellers:

  •  Buyers: It’s important to confirm that any renovations or additions on a prospective property were completed with the proper permits. Permits ensure the work was done to code, often by licensed professionals, and inspected for safety and compliance. Unpermitted work can lead to costly fixes, insurance issues, or even fines—especially if you’re planning future renovations or turning the property into a short-term rental.
  • Sellers: Unpermitted renovations can create major headaches during a sale. They may trigger delays, renegotiations, or even scare off buyers altogether. To avoid complications, sellers should gather documentation for all permitted work and consider retroactively permitting any unpermitted projects before listing. Having clear records not only smooths the transaction but also builds buyer confidence and adds value to your property.
