Do you need a building permit in Sanpete County, Utah?

Yes. A permit from the County Building Official is required before erecting, constructing, reconstructing or altering a building or structure in unincorporated Sanpete County.¹ The county describes most new homes, additions, remodels, structural changes, accessory structures, and electrical, plumbing or mechanical work as permit work.⁸ Utah's adopted construction standards apply to construction, alteration, remodeling and repair, subject to statewide and local amendments and statutory exceptions.⁹

Permit work is inspected, and a permit closes when the county issues a certificate of occupancy or records a passing final inspection.¹⁰ A permit becomes void after 180 days, but that period restarts whenever a building inspector passes a required inspection; the Building Official may grant an extension for extenuating circumstances.¹⁰ Occupancy requires a certificate of occupancy from the county Building Inspection Department unless the Building Official authorizes qualifying temporary occupancy.¹¹

Who is the Sanpete County building department, and how do you reach it?

The Sanpete County Building Department is the first stop for a project in the unincorporated county; its published process begins with registration in the online permit system.¹²⁸ The office is at 160 North Main, Suite 201, in Manti, and its phone number is 435-835-2113.⁸ Applicants may also need separate approvals from Planning & Zoning and Central Utah Public Health Department.¹²

Sanpete County Planning & Zoning manages zoning applications online and is at 160 North Main, Suite 203, in Manti; call 435-835-2115.¹³ A property inside city limits needs approval from the applicable city before the county permit application is submitted.¹⁴ Starting without a required permit may bring investigation fees equal to the permit fee, although the actual building-permit fee schedule could not be confirmed; ask the Building Department for the current amount.¹²

Does Sanpete County have zoning?

Yes. Sanpete County's land-use and zoning ordinance governs the unincorporated area, while incorporated cities and towns administer their own zoning approvals.²¹⁴ That distinction matters before relying on a county answer: confirm whether the parcel is inside municipal limits, then obtain the approval from the authority for that location.¹⁴

For an agricultural building exemption in unincorporated Sanpete County, Planning & Zoning approval must come before construction, the structure must be used exclusively for agriculture, and residential, commercial, industrial or other non-agricultural uses do not qualify.⁷ A qualifying agricultural land division must satisfy agricultural-use and zone-size conditions, and it cannot shift to non-agricultural use unless a later zone change permits that use.¹⁵ The county's available materials did not confirm one countywide minimum dwelling size, setback, or tiny-home classification; give Planning & Zoning the parcel number and proposed structure before committing to a design.⁵

How do septic permits work in Sanpete County?

Central Utah Public Health Department administers onsite wastewater permitting for Sanpete County under Utah's onsite wastewater rules.³ Contact the Manti office at 125 North 100 East or (435) 835-2231.¹⁶ Construction of any part of the wastewater system cannot begin until the health department has issued the construction permit.³

Public sewer connection is required when sewer is available and practicable; where it is not, the property must connect to an adequate onsite system or another acceptable wastewater system.¹⁷ Only about 6.2% of mapped county soils avoid a “very limited” rating for a conventional septic drain field, so a buyer should budget time for site evaluation and should not assume a standard drain field will work.¹⁸ The health department may apply stricter local requirements, charge administrative fees, require servicing and decide variances.¹⁹

Can you live in an RV or tiny home on land in Sanpete County?

Full-time residential living in a recreational vehicle on a parcel in unincorporated Sanpete County is prohibited.⁴ No more than 2 RVs may be permanently placed on a parcel, and each must be licensed, operable, ready for highway use, and equipped with self-contained sewage-disposal and water systems.⁴ An RV kept permanently or year-round, including a park model, must connect to a state-approved septic system and be winterized when not in use; permanent skirting and additions are not allowed.⁴

The county materials do not confirm how a structure marketed as a tiny home is classified for occupancy in unincorporated Sanpete County.⁵ Utah's RV-park sanitation rule allows a qualifying tiny house in an RV park under specified certification and inspection conditions, but that rule does not establish permission on a private parcel.²⁰ Ask Planning & Zoning to classify the exact unit and proposed use before purchase.¹³

Building a home in Sanpete County: what are the steps?

Confirm that the parcel is in unincorporated Sanpete County; property inside a city or town needs that municipality's zoning approval before a county permit application.¹⁴
Ask Planning & Zoning to confirm the parcel's allowed use and applicable development standards, then complete the zoning application online.¹³
Arrange wastewater review with Central Utah Public Health Department, because septic construction cannot start before the department issues its construction permit.³
Resolve access: a new driveway or business approach involving a county road requires contact with the Road Department, while access along a state highway requires a conditional UDOT access permit.²¹²²
Register in the county's online system and submit the building-permit application and supporting approvals.¹²⁸
Schedule required inspections and obtain a passing final inspection or certificate of occupancy before treating the project as complete.¹⁰¹¹

What should you check before buying land in Sanpete County?

Start with jurisdiction, legal access, water, wastewater feasibility and the buildable portion of the parcel. County zoning governs unincorporated land, but cities and towns handle their own zoning approvals.²¹⁴ For a driveway or business approach on a county road, contact the Sanpete County Road Department so the project can meet county guidelines.²¹ A state-highway connection or a change in access intensity requires UDOT's conditional-access process.²²

Terrain and ownership patterns can narrow the practical choices: about 37.7% of county land has a slope of 15% or less, and about 51.9% is federal land.²³²⁴ Conventional septic suitability deserves early attention because only about 6.2% of mapped soils avoid severe limitations for a conventional drain field.¹⁸ The median property-tax bill is about $1,536 per year at an effective rate near 0.5%, useful context rather than a parcel-specific quote.²⁵²⁶

Watch-outs

Sanpete County is not accepting or processing building-permit applications for projects accessing Pine Creek Road during the temporary development moratorium announced as of June 16, 2026.¹⁸
An owner-builder exemption is an exemption from contractor licensing, not from building permits, inspections, zoning or construction-code requirements.⁶
A structure used solely for agriculture and not for human occupancy may qualify for a state construction-code exemption, but plumbing, electrical or mechanical permits may still be required and Sanpete County requires Planning & Zoning approval first.²⁷⁷
Sanpete County regulates subdivision of land, and a qualifying agricultural division must meet the minimum size of its zoning district and remain in agricultural use unless a later zone change permits otherwise.¹⁵

Water rights & wells in Sanpete County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Utah’s water agency.

Closed to new supply

New water supply here generally requires a permit, an offset, or buying an existing right — a household well is not automatic.

Household wellPermit required — restricted

Utah has NO exempt domestic well — you must own a water right to drill any well, including a household well. In an open area you file a new appropriation, but because much of Utah is closed to new appropriation a newcomer typically must PURCHASE an existing water right and file a change application to move it to the new well.

Limit: ~0.45 acre-ft/yr indoor domestic (typical allocation); no statutory exempt-well quantity
