Thinking about turning your Conifer or Aspen Park home into a short-term rental, but not sure what’s legal? You’re not alone. With Jefferson County rewriting its rules, it can feel tricky to know where to start and what to prepare. In this guide, you’ll learn the proposed pathway to operate legally, what documents and safety steps you’ll need, and the local constraints that matter most in Conifer. Let’s dive in.
What’s changing in Jefferson County
Jefferson County has published a draft Short-Term Rental (STR) regulation and invited public input. The county reports more than 700 advertised STRs in unincorporated Jeffco and fewer than 50 with permits, which is driving the update. You can review the process and timeline on the county’s STR Regulations Update page and read the full draft regulation.
Here’s the key takeaway: the county is moving to a clear licensing system with defined safety, wildfire, parking, insurance, and operational rules. The public comment period ran through July 20, 2025, and final adoption details may change. Always check the county’s project page for the latest updates.
Confirm your property’s eligibility
Verify jurisdiction
Start by confirming your address is in unincorporated Jefferson County, which includes most of Conifer and Aspen Park. If your property is inside a municipality, that city’s rules apply instead. Use the county’s STR Regulations Update page to find tools or contacts to verify.
Check HOA or CC&R rules
County approval does not override your HOA. Many mountain subdivisions regulate or prohibit STRs. The draft requires you to notify your HOA before applying and to provide an affidavit that you did so. If your CC&Rs prohibit STRs, you cannot proceed at the county level.
Know your license type
The draft creates two license types:
- Primary Residence STR. You live in the home at least 9 months per year. Primary residence STRs are exempt from the separation distance and district cap.
- Investment Property STR. You do not live in the home at least 9 months per year. These are subject to spacing and cap limits. Only owners may hold an STR license, according to the draft. Details are in the draft regulation and the county’s summary sheet.
The legal pathway: step by step
Before you apply
Gather the documentation the draft requires:
- Proof of ownership.
- Proof of water and sewer. If you have a well or onsite wastewater system, provide permits and annual pumping/inspection records.
- Wildfire mitigation. Demonstrate defensible space compliance in the Wildland Urban Interface and plan for recertification every 3 years.
- Fire protection verification. A statement from your local Fire Protection District confirming adequate emergency access and response.
- Liability insurance. Minimum of 500,000 dollars with explicit STR coverage.
- Safety equipment. Smoke and CO alarms, and fire extinguishers per code.
- Parking and trash plans. Minimum off-street parking of one space plus one per bedroom. Bear-proof trash storage and service.
- Local representative. A 24/7 contact within 30 minutes of the property whose information is posted and provided to guests.
Apply and get approved
Per the draft, applications will be accepted on a first-come, first-served basis beginning 30 days after the Board of County Commissioners approves the rules. Expect an administrative review and published fees set by the Board. If denied or later revoked, appeals go to the Board of Adjustment.
Operate within the rules
- Occupancy limits are typically 2 people per bedroom, up to a maximum of 10 occupants. Accessory dwelling units may have stricter limits.
- Investment STRs must meet a 750-foot separation from other permitted STRs and fit within a cap of up to 1 percent of dwelling units within the Fire Protection District. Primary residence STRs are exempt from both the separation and the cap.
- Licenses are for one year, non-transferable. Revocation can lead to a 5-year ineligibility period.
- Every advertisement must list your county STR license number and the approved occupancy limit. Colorado law allows counties to require platforms to delist non-compliant properties. See HB23-1287 for context on platform obligations.
Taxes and registration basics
Short-term stays are typically taxable. Colorado imposes a base state sales tax rate commonly cited as 2.9 percent, with local sales and lodging layers that vary by location. Owners often need to register with the Colorado Department of Revenue to report and remit taxes. Some marketplaces collect certain taxes, but you are ultimately responsible for full compliance. For background on state authority and tax obligations, see the Colorado Lawyer overview of STRs and legislation here.
Local rates in unincorporated Jeffco and the Aspen Park area differ from nearby municipalities. The Evergreen Area Chamber’s local references illustrate how composites vary and why you should verify your exact rates using state and county tools. Review their local tax composites as a starting point, then confirm with official sources.
Conifer-specific constraints to plan for
- Wildfire risk and defensible space. Conifer and Aspen Park are in the Wildland Urban Interface, and the draft requires defensible space compliance with ongoing recertification. Learn more about Jeffco’s wildfire context in the county’s WUI FAQ.
- Access, emergency response, and utilities. Narrow roads, winter conditions, and private wells or septic can affect eligibility and timelines. The draft requires maintained road access, fire district verification, and complete water/sewer documentation.
- Insurance availability and cost. Carriers may price STR coverage higher in high wildfire risk areas. The draft requires at least 500,000 dollars in liability coverage with STR use clearly included.
- Enforcement and penalties. The county highlights low historical compliance and intends to use clearer standards and platform enforcement. Non-compliance can lead to fines, revocation, and a five-year ineligibility period.
Quick prep checklist
- Confirm your address is in unincorporated Jefferson County.
- Read the county’s STR Regulations Update page and the full draft regulation.
- Check HOA CC&Rs and notify your HOA as required by the draft. Keep written proof of notification.
- Compile documents: deed, water/sewer proof, OWTS records if applicable, floor plan, parking plan, trash plan, insurance with 500,000 dollar minimum, wildfire defensible space proof, and local representative details.
- Prepare guest materials and on-site posting for your STR license and rules.
- Register for state tax accounts as needed and verify which taxes platforms collect versus what you must remit.
- Budget for application fees, wildfire mitigation, inspections, and insurance premiums.
- If you own multiple properties, review any ownership limits in the draft.
Common mistakes to avoid
- Listing without a county license number once licensing is required.
- Overlooking HOA restrictions or skipping the HOA notification step.
- Missing wildfire mitigation or letting defensible space recertification lapse.
- Ignoring parking minimums or bear-proof trash requirements in mountain areas.
- Assuming platforms handle all taxes without confirming your filing duties.
