Unincorporated Uintah County, Utah requires building permits for homes and other regulated construction, and Uintah County Community Development accepts complete permit applications online.12 The county zones unincorporated land through its Planning & Zoning Division, while Ballard City, Naples City and Vernal City are listed separately for their own planning and zoning.34 Septic permits and inspections come from TriCounty Health Department, not the building or zoning office.5

Do you need a building permit in Uintah County, Utah?
Yes. Uintah County requires a permit for construction, enlargement, alteration, repair, moving, demolition, occupancy changes, and regulated electrical, gas, mechanical, or plumbing work.1 The requirement is subject to the Utah-adopted construction code and its exemptions.1
Some small projects can be exempt, including a qualifying detached one-story accessory structure no larger than 200 square feet and a qualifying unattached deck no larger than 200 square feet and no higher than 30 inches above grade.1 Agricultural structures have a separate conditional path: the building must be solely for agricultural use and not human occupancy, and electrical, plumbing, or mechanical work may still require permits.10 Ask Community Development for a project-specific decision and obtain that decision in writing when staff determines that no permit is necessary.1
Who issues building permits in Uintah County, Utah?
Uintah County Community Development is the starting office for building permits and planning or zoning questions.12 The department's official page lists its office at 152 E 100 N in Vernal and its phone as (435)-781-5336.12
Gather every required document and plan before applying through the county's online permit portal; Uintah County says incomplete applications will be returned.2 The county administers permit requirements under Utah's adopted construction standards, which apply to regulated construction, alteration, remodeling, and repair.13 If the county collects an inspection fee but cannot provide an inspection within 3 business days of the request, Utah law allows the applicant to use an approved third-party inspection firm.14 That inspection alternative does not remove the permit or code requirements.14 The county's fee schedule, enacted January 10, 2022, lists building permit fees by building type and size, including $0.70 per square foot for residential construction, plus plan-check fees of $150 for 0-1499 square feet, $300 for 1500-4999 square feet and $400 for 5000 square feet and over; confirm the current schedule with Community Development before budgeting.15
Does Uintah County have zoning?
Yes. Uintah County Community Development has a Planning & Zoning Division and publishes a Zoning Code for the unincorporated county.3 Ballard City, Naples City and Vernal City are listed separately for planning and zoning, so a parcel inside one of those cities follows that city's rules, while septic permits still come from TriCounty Health Department.45 For land outside cities and towns, Utah law authorizes counties to control land use in unincorporated areas, including uses, density, open space, structures, and buildings.16
Utah protects a manufactured home wherever a single-family residence is permitted, including in unincorporated Uintah County, but the home must have a code-compliant permanent foundation and meet the land-use rules, building codes, and restrictive covenants that apply to a single-family residence in the same area.11 A parcel's zoning district still matters before choosing a homesite or assuming an RV, tiny home, setback, or particular lot coverage is allowed. Uintah County's general minimum dwelling size and general lot-coverage schedule could not be confirmed; bring the parcel number and proposed use to Community Development.12
Dividing land is a separate approval. The county's subdivision title governs the subdivision, platting and recording of all land in the unincorporated area, and no building permit may be issued until the final plat is approved and recorded.17
How do septic permits work in Uintah County?
TriCounty Health Department, which serves Daggett, Duchesne and Uintah counties, reviews and approves system plans, issues septic construction permits and conducts inspections in Uintah County.56 The Vernal office publishes onsite-wastewater materials and lists 133 South 500 East, Vernal, UT, 84078, (435) 247-1177, and vernal@tricountyhealth.com.18
Utah's statewide onsite-wastewater rule is administered locally, and local health departments may impose stricter requirements.19 A property must connect to public sewer when connection is available and practicable; otherwise it needs an adequate onsite system or another accepted wastewater system.20 Only about 21.8% of mapped county soils avoid a severe limitation rating for a conventional septic drain field, so make the site evaluation an early contingency rather than assuming a standard field will work.21 Existing-system verification can require an open tank, a qualified inspection, and recent pumping when records are missing or old.22
Can you live in an RV or tiny home in Uintah County?
The Uintah County zoning administrator may approve one travel trailer for occupancy on a property, with approved water, sewer and electrical utilities, and it may not be rented out.7 In the RFM and MG-1 zones the property can be vacant; in all other zones the trailer must sit on a property that already has a permitted dwelling.7 One travel trailer may also be approved for up to one year while a building permit is active.7 A camping trailer, tent or other recreational vehicle is not a permanent dwelling, and temporary living quarters need zoning authorization or a campground or RV-park conditional-use permit.7 Ask Community Development about the parcel's zoning district and which approval applies.12
Utah's RV-park rule does not answer whether a person may occupy an RV on an individual private parcel; it governs qualifying RV parks and requires compliance with local zoning and other codes.23 Tiny-home permission outside an RV park depends on local land-use treatment, including whether the unit is considered a primary dwelling, accessory dwelling, modular unit, or manufactured home.8 A qualifying manufactured home has a clearer path: Uintah County cannot exclude it from an area where a single-family residence is permitted, provided it has a code-compliant permanent foundation and meets the same applicable land-use rules, building codes, and restrictive covenants.11
Building a home in Uintah County: what are the steps?
- Give Community Development the parcel number and proposed home type, then confirm zoning, setbacks, access, and the full application checklist.312
- Resolve wastewater early with TriCounty Health Department, which issues the septic construction permit and inspects the installation.6
- Assemble every required plan and supporting document before using the county's online portal, because incomplete applications are returned.2
- If acting as an owner-builder, complete the county's owner-builder documentation and stay within Utah's licensing-exemption conditions; building permits and inspections still apply.249
- Coordinate driveway and utility work affecting a county road with the Roads Department; new construction sites outside qualifying improved subdivisions require an encroachment permit for driveways, utilities, and related improvements.2526
- Schedule required inspections as construction proceeds and do not cover work before the relevant inspection.1422
What should you check before buying land in Uintah County?
Start with a parcel-level zoning and buildability review through Community Development, then make wastewater feasibility, legal access, and water service or water rights part of due diligence.3126 A private well needs a water right first: Utah well drillers cannot drill until the State Engineer gives permission, which comes with approval of the water right.27 A driveway connecting to a county road can require county encroachment approval, while a new or intensified connection along a state highway requires a UDOT conditional access permit.2528
Soils deserve special attention because only about 21.8% of mapped county soils avoid a severe limitation rating for conventional septic drain fields.21 Uintah County averages about 12 inches of precipitation annually, and severe drought has occurred in about 31.6% of measured years.2930 Federal land covers about 58.7% of the county, so verify ownership, recorded access, and the exact boundaries rather than relying on a listing map.31 The effective property-tax rate is about 0.5%, with a median annual property-tax bill of about $1,447.3233
Watch-outs
- An agricultural building is not automatically permit-free; Uintah County makes the determination, and installed electrical, mechanical, or plumbing work is not exempt.10
- A county-road driveway or related utility installation for new construction may need an encroachment permit before work begins.25
- Tiny-home occupancy and a general minimum home size could not be confirmed, and a travel trailer needs the zoning administrator's approval before anyone lives in it; ask Community Development for a written parcel-specific answer.712
