Do you need a building permit in Huerfano County, Colorado?
Yes. Habitable structures in unincorporated Huerfano County require a county building permit.1 The county has adopted building codes, and its ordinances page says the adopted editions change in 2026.9 An accessory building larger than 120 square feet may not be built on vacant land without a permit.1
An owner may pull the permit, but an owner-builder must sign a letter of understanding with the Huerfano County Building Authority board concerning the use of subcontractors.6 Agricultural structures should not be assumed exempt: Colorado law allows counties to except structures used solely to shelter agricultural implements, farm products, livestock or poultry, but the project still needs a county determination.10
Who issues building permits in Huerfano County?
Huerfano County Land Use and Building is the starting point for building permits, land-use applications, planning, zoning and code enforcement.3 The office is at 401 Main Street, Suite 304, Walsenburg, CO 81089, and the phone number is 719-738-3000 ext 103.3 The office lists hours from 7:30 a.m. to 5:30 p.m., Monday through Thursday.3
Huerfano County uses MyGov for contractor registrations, permits and license applications, and applicants can submit and participate in projects online.3 Residential applications require a site plan, sanitation and water documentation, proof of ownership or authorization, and any other applicable submittals.11 Processing time varies by application, so confirm the current checklist and review sequence before ordering plans or scheduling work.11
Does Huerfano County have zoning?
Yes. Development in unincorporated Huerfano County is governed by mapped zoning districts, county zoning regulations and the county comprehensive plan.2 The Land Use and Building office says county development is guided by the zoning regulations and procedures and the comprehensive plan adopted in 2025.3 Colorado county zoning authority can regulate building location, height, bulk, lot coverage, lot size, open space, density and land uses in unincorporated territory.12
That means a parcel's zoning district matters before choosing a house location, setback, tiny home or other use.2 We could not confirm one countywide minimum home size or a current rule for accessory dwelling units in unincorporated Huerfano County. Ask Huerfano County Land Use and Building to identify the parcel's district and the standards that apply to the proposed use.3
How do septic permits work in Huerfano County?
The Las Animas-Huerfano Counties District Health Department permits the installation, repair and use of on-site wastewater treatment systems in Huerfano County.4 A septic permit application and the appropriate fee must reach the department before installation begins.13 Colorado law also requires a permit before an on-site system is constructed, altered, installed, repaired or used where a building is not served by a sewage treatment works.5
After permitted work is complete, a final inspection must occur before the system is used, and occupancy approval for a building without sewer service depends on final septic approval.14 Only 23.8% of county soils avoid a severe USDA limitation rating for a conventional drain field, so make septic feasibility an early site question.15 Contact the health department's Huerfano County office at 119 E 5th Street in Walsenburg or 719-738-2650.13
Can you live in an RV or tiny home in Huerfano County?
We could not confirm a complete current rule for living in an RV on private land in unincorporated Huerfano County. Because the county has zoning, ask Huerfano County Land Use and Building whether the parcel's district allows the proposed occupancy and what permits or time limits apply.23 Colorado's statewide camping rule for Colorado Parks and Wildlife land does not answer the private-land question.16
Colorado-approved tiny homes may be used for long-term living, but plans must receive state approval before construction, the unit must meet applicable codes, and local zoning must allow the site.7 A manufactured home likewise may be installed only where local zoning permits it, with state installation requirements and local foundation or structural rules also applicable.17
Building a home in Huerfano County: what are the steps?
- Ask Huerfano County Land Use and Building to confirm the parcel's zoning district, allowed residential use and applicable site standards.23
- Establish legal water and wastewater plans; every new groundwater-diverting well needs a state permit subject to statutory and basin-specific rules, while an on-site septic system needs local health approval.85
- Prepare the county application with a site plan, sanitation and water documents, ownership or authorization evidence, and other applicable materials.11
- Submit the building or land-use application through the county's online portal or work with the Land Use and Building office.3
- Complete the permitted septic work and final health inspection before use or occupancy.14
- If the driveway connects directly to a state highway, obtain a Colorado Department of Transportation access permit.18
What should you check before buying land in Huerfano County?
Start with the parcel's zoning district, allowed use, setbacks and access before treating vacant land as buildable.2 A direct residential driveway onto a Colorado state highway requires a state access permit, and the permit holder is responsible for required roadway improvements.18 Development in a regulated floodplain must meet local rules that equal or exceed federal minimum design and construction criteria.19
Test the water and septic assumptions early: a new groundwater well generally requires a state permit, and only 23.8% of county soils avoid a severe conventional-drain-field limitation rating.815 The county receives about 17.8 inches of precipitation annually and has experienced severe drought in 29.3% of years, which makes a dependable water plan especially important.2021 The effective property-tax rate is about 0.3%, with a median annual bill of $707.2223
Watch-outs
- The county ordinances page says newer building-code editions took effect in 2026, while the land-use page also references earlier editions; confirm the code edition for a new application.9
- A building permit for a property without sewer service cannot be approved until the local health agency has issued the septic permit.24
- We could not confirm a complete current private-land RV occupancy rule; ask Huerfano County Land Use and Building before using an RV as a residence.23
