Short-Term Rental (STR) Investment Guide: Jefferson County, Colorado

Overview

Yes, short-term rentals are allowed in Jefferson County, Colorado, but the process is currently complex and has historically resulted in very low compliance rates. As of recent data, Jefferson County estimates over 700 advertised STR units in unincorporated areas, yet fewer than 50 have obtained proper permits, representing a compliance rate of less than 7%. The county acknowledges that the current regulations are problematic and is actively working to reform the process to improve compliance.

How to Start a Short-Term Rental Business in Jefferson County, CO

The current process requires a two-step approach for all STRs:

Step 1: Special Exception Approval

• Apply to the Board of Adjustment (BOA) for a Special Exception before pursuing any permits
• This step is mandatory for all STR applications
• Timeline: Approximately two months from application submission to BOA hearing/decision
• Process is costly and time-intensive, contributing to low compliance rates

Step 2: STR Permit Application

• Apply for Short Term Rental Permit through Planning & Zoning Division
• Only available after BOA Special Exception approval
• Initial validity: 6 months from approval
• Renewal: Required every 6 months for the first year, then annually thereafter

Future Process (Proposed 2025 Updates)

The county is proposing significant reforms that would:

• Eliminate public hearing requirements for new and renewal STR permits
• Replace subjective criteria with clear, objective administrative standards
• Streamline the process to reduce costs and timelines
• Create separate categories for different STR types
