Unincorporated Clear Creek County, Colorado requires a county building permit for a new home1. Planning reviews the project for zoning compliance, and a property without sewer service needs an approved onsite wastewater treatment system before building approval23. Start with the Site Development Department because access, grading and floodplain work can require separate permits45.

Do you need a building permit in Clear Creek County, Colorado?
Yes. A new residence in unincorporated Clear Creek County requires a building permit from the county Building Department1. The county regulates the design, construction, use and occupancy of buildings in those unincorporated areas14. Clear Creek County has adopted the 2024 International Residential, Building, Plumbing and Mechanical codes with local amendments6. Permit fees are not a single flat amount; the county calculates the fee during processing from the project's size and scope15. A homeowner who occupies or intends to occupy the residence may act as the contractor, but that owner-builder status does not remove the building-permit, zoning or inspection requirements, and hired plumbing or electrical subcontractors must hold the applicable Colorado license10.
Who issues permits in Clear Creek County, and how do you reach them?
The Clear Creek County Building Department handles building permits and inspections for unincorporated property; call (303) 679-2446 or email [email protected]14. The Clear Creek County Planning Department administers zoning, subdivision and other land-use regulations; call (303) 679-2436 or email [email protected]16. Both offices are at 1111 Rose Street, Georgetown, Colorado1416. Clear Creek County Environmental Health handles new septic construction, repairs and use permits at (303) 679-2428 or [email protected]17. For grading, driveways and floodplain work, contact Site Development at (303) 679-2436 or [email protected]18. These departments have distinct approvals, so a building permit does not by itself settle zoning, access, earthwork or wastewater questions248.
Does Clear Creek County have zoning?
Yes. Clear Creek County zoning governs buildings and land uses in unincorporated areas, while an incorporated municipality may apply its own zoning inside town or city limits2. County Planning reviews building permits for permitted uses, building height, signs, animals and other zoning standards2. Setbacks depend on the parcel's zoning district, and a planned development can have its own setback requirements7. A permitted accessory dwelling unit is recognized in the county rules, but that does not mean every parcel qualifies for one19. We could not confirm a countywide numeric minimum lot size or lot-coverage cap, so ask Planning for the parcel's zoning designation and applicable dimensional table before designing a house, tiny home or accessory unit716.
How do septic permits work in Clear Creek County?
Clear Creek County Environmental Health is the local office for onsite wastewater treatment system permits, including new construction and repairs817. Colorado requires an OWTS permit before a system is constructed, altered, installed or used where a building lacks sewer service20. For a building without sewer service, the local health agency must issue the OWTS permit before building construction or remodeling approval3. A final OWTS inspection and local approval are required before the system is placed in use and before occupancy approval9. The site deserves early investigation: 0% of mapped county soils are rated free of severe limitations for a conventional septic drain field, so budget for a site evaluation and the possibility of an engineered design21. A finaled driveway permit is also required before an OWTS permit may be issued4.
Can you live in an RV or tiny home on your land in Clear Creek County?
A tiny home intended for long-term living can follow Colorado's approval path, but its plans must be approved by the Colorado Division of Housing before construction and the unit must also satisfy applicable codes and local zoning11. State certification is site-specific, so moving the unit to another Colorado site can require revised approval when design criteria differ11. Clear Creek County's district-specific zoning and setbacks still control whether a proposed site works27. We could not confirm a rule for long-term RV occupancy or temporary camping on private land in unincorporated Clear Creek County. Ask the Planning Department about the parcel and proposed duration before using an RV as housing, because the county administers zoning and land-use regulations162.
Building a home in Clear Creek County: the steps, in order
- Start with Site Development on legal access, driveway design, grading and any floodplain issue; the department administers the county's driveway and flood-damage rules185.
- If the home will not use sewer service, secure the OWTS permit from Environmental Health before seeking building approval317.
- If groundwater will supply the home, obtain the required well permit from the Colorado Division of Water Resources13.
- Submit the house plans and building-permit application to the Building Department under the county's adopted codes16.
- Complete required inspections, including final OWTS approval before occupancy when the property is not served by sewer9.
What should you check before buying land in Clear Creek County?
Access, slope and wastewater feasibility deserve attention before closing. Only 17.8% of Clear Creek County land has a slope of 15% or less, and 78% is wooded2223. The county requires permits for new or modified driveway access, and a direct connection to a Colorado state highway requires a state access permit424. Floodplain improvements require county approval, so compare the parcel with the adopted flood maps and ask Site Development about any hazard boundary518. Every new groundwater-diverting well needs a state permit, subject to statutory and basin-specific rules13. Finally, verify that the legal parcel can support the intended use, setbacks, access and OWTS before treating it as buildable2720.
Watch-outs
- Do not assume a mining claim or steep mountain parcel is buildable; confirm zoning, legal access, driveway feasibility and wastewater approval before closing2420.
- Clear Creek County's mapped soils rate 0% free of severe conventional drain-field limitations, so septic feasibility can change the design and cost of a project21.
- Long-term RV occupancy and private-land camping limits were not confirmed; ask County Planning for a parcel-specific answer before moving an RV onto the land162.
