Construction projects in Hinsdale County, Colorado require a building permit, and the county administers zoning and planning regulations1. The Hinsdale County Building Department also receives onsite wastewater treatment system applications and handles building, zoning and development questions1.
Do you need a building permit in Hinsdale County, Colorado?
Yes.
Yes. Construction projects in Hinsdale County and the Town of Lake City require a building permit1. A complete submittal includes the application, fee, stamped construction plans and specifications, use-tax declaration, and use-tax payment1. The county uses the 2015 International Code Council building codes, while electrical and plumbing permits go through the State of Colorado1.
Do not start construction before the Building Official approves the permit and the required fees are paid1. Building-permit fees depend on the structure's valuation; alteration and remodeling fees depend on material cost4.
Who issues building permits in Hinsdale County, and how do you reach them?
The Hinsdale County Building Department is the starting point for building permits, building codes, ordinance enforcement, zoning, development questions, floodplain applications, and OWTS applications.
The Hinsdale County Building Department is the starting point for building permits, building codes, ordinance enforcement, zoning, development questions, floodplain applications, and OWTS applications1.

Does Hinsdale County have zoning?
Yes.
Yes. Hinsdale County administers zoning and planning regulations, and the Building Department answers questions about county building, zoning, and development1. Colorado law allows county zoning in unincorporated territory, including controls on building location, size, lot size, uses, density, open space, and solar access5.
The available county material does not confirm numeric setbacks, minimum lot size, minimum dwelling size, lot coverage, building-height limits, or district-by-district uses. Ask the Building Department for the zoning district and current standards tied to the parcel before relying on a listing description or planning a site layout1.
How do septic permits work in Hinsdale County?
Hinsdale County's Building Department receives onsite wastewater treatment system applications.
Hinsdale County's Building Department receives onsite wastewater treatment system applications1. If a property is outside a water and sanitation district, the building-permit package requires evidence of potable water and an approved OWTS permit; property inside a district instead requires evidence that water and sewer taps have been paid4. Colorado requires an OWTS permit before construction, alteration, installation, repair, or use where a building is not served by a sewage treatment works6.
A final OWTS inspection must occur after permitted work is complete and before the system is used; the local public health agency or its designated engineer checks compliance6. Only 0.8% of mapped county soils avoid a “very limited” rating for conventional septic drain fields, so establish septic feasibility early7. Ask the Building Department what site testing and design the parcel requires1.
Can you live in an RV or tiny home on land in Hinsdale County?
We could not confirm a county rule that answers whether an RV may be occupied on private land, either temporarily or while building.
We could not confirm a county rule that answers whether an RV may be occupied on private land, either temporarily or while building. Ask the Hinsdale County Building Department for a parcel-specific answer before placing or occupying an RV, because the office handles zoning and development questions1.
Colorado-approved tiny homes are intended for long-term living, but plans require state approval before construction and the home must meet county zoning and site requirements2. A HUD manufactured home likewise may be installed only where local zoning allows it2. We could not confirm Hinsdale County's minimum dwelling size, manufactured-home district rules, or accessory-dwelling eligibility, so take the proposed unit and parcel details to the Building Department before buying1.
Building a home in Hinsdale County: what are the steps?
Ask the Building Department to identify the parcel's zoning, development standards, and any floodplain issue.
- Ask the Building Department to identify the parcel's zoning, development standards, and any floodplain issue1,4.
- Establish water and wastewater service: show paid water and sewer taps inside a district, or document potable water and obtain an OWTS permit outside one4.
- Prepare the building application, stamped plans and specifications, use-tax declaration, and required payment before starting1.
- Obtain separate state electrical and plumbing permits and any applicable road-cut or floodplain documentation1.
- Wait for approval and fee payment before construction begins1.
- Schedule county inspections at least one working day ahead and document state electrical and plumbing finals4.
- Complete the final inspection before the certificate of occupancy is issued4.
What should you check before buying land in Hinsdale County?
Start with buildability, not just acreage.
Start with buildability, not just acreage. Only 20.7% of the county's land has a slope of 15% or less, and only 0.8% of mapped soils avoid severe limitations for a conventional septic drain field7. Confirm a usable building envelope, OWTS feasibility, legal access, and the parcel's zoning before closing1.
A new groundwater well generally needs a Colorado Division of Water Resources permit, subject to statutory exceptions and basin-specific rules3. Direct residential access to a Colorado state highway requires a CDOT access permit8. County building projects in a floodplain also require a floodplain development permit when applicable4. For budgeting context, the effective property-tax rate is 0.3% and the median annual property-tax bill is $1,2867.
Watch-outs
- Do not begin construction before building-permit approval and fee payment1.
- Electrical and plumbing permits and inspections go through the State of Colorado rather than the county Building Department1,4.
- RV occupancy and numeric county zoning standards remain unconfirmed; ask the Building Department before committing to a design or purchase1.
- Colorado's owner-work exemptions are limited: they cover an owner's repair or maintenance in certain county licensing programs and condition electrical and plumbing work on the owner's property, but do not create a blanket exemption for building a new home9,10.
