Thinking about a second home in Idaho Springs and wondering if you can offset costs with short stays? You are not alone. This mountain town is a quick escape from Denver, and the short-term rental rules can be workable if you understand where your property sits and which permits apply. In this guide, you will learn how city and county rules differ, what taxes you must plan for, how to check HOA limits, and a simple way to estimate revenue. Let’s dive in.
City vs. county rules at a glance
The biggest Idaho Springs rental mistake is assuming one set of rules covers the whole area. It does not. Properties inside the City of Idaho Springs follow city rules. Properties outside city limits in unincorporated areas follow Clear Creek County rules. That single detail changes permit options and availability.
City of Idaho Springs rules
- A city short-term rental license is required for stays under 30 days, and the city caps the total number of licensed STRs at 15 at any one time. You can review the program and see where the city stands on licensing on the City Clerk’s page for short-term rentals. Visit the official City of Idaho Springs STR page for details and the public list of licensed STRs.
- The city distinguishes STRs from bed-and-breakfasts and home occupations, so make sure your intended use matches the city’s STR category.
Reference: See the City’s STR licensing and cap on the City Clerk’s page: Idaho Springs short-term rentals.
Unincorporated Clear Creek County rules
- A county license is required for STRs in unincorporated Clear Creek County. The county defines short-term rentals as stays under 30 consecutive days.
- License types include Standard (non‑primary or absentee), Primary Resident – Seasonal, and Primary Resident – Occupied.
- The county caps non‑primary permits at 4.5% of unincorporated housing stock. For 2025, that equals 162 permits, and the county notes these were fully allocated with an active waitlist. This makes new absentee STR entries difficult unless a permit opens up.
- Primary‑resident options have limits. County guidance shows a seasonal primary license may not be rented more than 120 days in a one‑year license period. County officials have discussed adjustments in recent meetings, so you should verify the current year’s limits.
- Expect approval steps that include a building‑safety checklist or inspection, proof of legal water supply and proper sewage or OWTS permits, and short‑term‑rental specific liability insurance. County materials state that host protections like AirCover may not be acceptable as insurance.
- Operational rules include a local 24‑hour contact with residence or business within about one hour, good‑neighbor rules, occupancy limits, and record‑keeping. Enforcement is active, and the county provides a license lookup and interactive map.

How to confirm your parcel’s jurisdiction
- Do not guess. Ask your agent to confirm whether the parcel is inside city limits or in unincorporated Clear Creek County. The answer determines which set of rules and caps apply.
- Use the city and county STR resources and license lookup tools, and review parcel maps before you write an offer.
Taxes you must plan to collect
Short-term rentals in Colorado are subject to tax on rooms and accommodations for stays under 30 days. Most cleaning fees and similar charges are also taxable. While some booking platforms may collect certain taxes, owners remain responsible for correct registration and remittance.
- State: Review the Colorado Department of Revenue guidance for rooms and accommodations to understand what is taxable and how to register. See the state’s overview: Colorado rooms and accommodations tax rules.
- County and municipal: Clear Creek County has historically used a 2% county lodging tax, and municipalities may add their own lodging taxes. Always confirm current rates and filing steps. A quick way to check listed tax rates is to review Colorado’s DR 1002 publication: Colorado DR 1002 reference.
Plan your budget as if you will be filing state sales tax and any applicable county or municipal lodging tax. Keep records and verify who is collecting on each platform and what remains your responsibility.
HOAs and deed restrictions matter
Even if the city or county allows STRs, an HOA can prohibit or limit them through recorded covenants or rules. An HOA restriction is often decisive, so you should confirm association documents early in the process. Learn how HOAs commonly manage these limits and what to look for in covenants: HOA restrictions on short-term rentals.
Colorado’s Common Interest Ownership Act sets the framework for amending association declarations and rules. Changes usually require a formal owner vote and can be difficult to achieve. You can review the statutory framework here: Colorado CCIOA statute.
Use this quick HOA request:
- “Please send the CC&Rs, any rental policy or addendum, and the minutes from the last two years that mention rental or short-term rental policy.”
When you review documents, look for:
- Minimum lease terms and any explicit STR bans or caps.
- Registration or permit steps for owners who rent.
- Insurance requirements, deposits, or additional fees.
- Voting thresholds and processes to amend rental rules.
Demand and seasonality in Idaho Springs
Idaho Springs earns strong weekend interest because it sits about 33 miles from Denver, often a 40‑minute drive in regular conditions. Travel writers highlight the town’s easy day‑trip appeal from the Front Range. See this overview of top Denver day trips: Best day trips from Denver.
What draws guests year‑round:
- St. Mary’s Glacier for hiking and alpine views in all seasons. Explore the area overview here: St. Mary’s Glacier on AllTrails.
- Echo Mountain for skiing and tubing, often among the closest winter options to Denver.
- Indian Hot Springs and the downtown Miner Street scene for dining and casual shopping.
- Anticipated local projects, such as the proposed Mighty Argo cable car and trail investments, which could boost demand if realized. Read about the concept: Mighty Argo cable car overview.
These drivers tend to lift winter weekends and holiday periods, with steady summer demand tied to hiking, rafting, and road‑trip traffic. Shoulder seasons can be softer unless you emphasize year‑round features like hot tubs, views, and easy access to downtown.
Estimating revenue the right way
Instead of relying on a single number, build a simple model that uses real comps and conservative assumptions. Idaho Springs is a small market, so paid data or manager input goes a long way.
- Start with platform comps. Browse current listings to size up supply, styles, and starting prices. For a quick snapshot of active listings in town, review the Idaho Springs stays page on Airbnb. Expect prices and occupancy to vary by location, size, and season.
- Pull 6 to 12 comps that match your bedroom count, guest capacity, and neighborhood. Note nightly rates for peak periods and shoulder seasons.
- Ask a local property manager for recent ADR and occupancy on similar homes, or purchase a paid market report to reduce noise.
- Model a conservative occupancy range. Many mountain homes land in a 40% to 70% annual occupancy band, depending on features and management. Multiply expected ADR by booked nights to get gross revenue, then subtract platform fees, cleaning, utilities, insurance, taxes, and a maintenance reserve to estimate net.
What lifts rates and occupancy:
- Proximity to downtown, trailheads, hot springs, and I‑70.
- Beds and baths, parking, pet friendliness, fast internet, and a private hot tub.
- Strong reviews, fast response times, and dynamic pricing.
Due‑diligence checklist before you write an offer
Work through this list with your agent so you understand both permissions and costs.
- Confirm jurisdiction. Is the parcel inside Idaho Springs city limits or in unincorporated Clear Creek County? Your permit path depends on this. Use the county and city STR pages and license lookup tools: Clear Creek County STRs and City STRs.
- Check STR license eligibility. Is the property already licensed, and if so, under which program? If in unincorporated county and you plan absentee use, ask if a non‑primary permit is available or if you will go on a waitlist.
- Review HOA documents. Request CC&Rs, rental policies, and recent minutes that mention STRs. Look for any bans, minimum stays, or added fees. See common HOA approaches here: HOA restrictions on STRs.
- Verify utilities and safety. Gather proof of legal water supply and sewer or OWTS permits if applicable. Plan for a building‑safety checklist or inspection as part of licensing.
- Confirm insurance. Price a short‑term‑rental specific liability policy. Note that county materials say general host protections like AirCover may not meet requirements.
- Plan parking and access. Count off‑street spaces and think through winter conditions and I‑70 traffic patterns.
- Name a local contact. County rules require a 24‑hour local contact within about one hour. Document who will serve in that role if the property is in the unincorporated county.
- Register for taxes. Understand your state sales tax registration and any county or municipal lodging tax filings. See the state’s rooms and accommodations guidance: Colorado DOR overview and check listed local rates on DR 1002.
- Set a reserve. Hold funds for maintenance, winterization, emergency repairs, and seasonal turnover.
What this means for different buyers
Weekend retreat owners
If you want a personal getaway first, with some rental offset, focus on properties that fit your lifestyle and pass the permit test. In the city, confirm if the 15‑license cap has room. In the county, see if you qualify under a primary‑resident category and whether those day limits work for your goals.
Primary residents who rent occasionally
The county’s primary‑resident license types can offer flexibility if this will be your main home and you plan seasonal or occasional rental. Review the day limits and confirm the current year rules with the county so your plan fits the license type.
Investors seeking income
In unincorporated Clear Creek County, non‑primary permits are capped at 4.5% of housing stock, with 162 permits set for 2025 and an active waitlist. Inside the City of Idaho Springs, only 15 total STRs are allowed at a time. These caps significantly limit new absentee STR entries, so factor regulatory availability into your underwriting from day one.
