Building permits, zoning and septic rules in Garfield County, Utah

Garfield County requires building-permit approval before erecting, constructing, reconstructing, altering, or changing the use of a building or other structure¹⁰. Utah's current construction standards include the 2024 International Building Code and the 2021 International Residential Code, together with statewide and local amendments¹¹. A structure used solely for agriculture and not for human occupancy is exempt from the State Construction Code, but plumbing, electrical, or mechanical work may still need a permit; the exemption narrows for certain small parcels inside municipalities or county-approved subdivisions¹². Permitted work must remain exposed and accessible until approved, and Garfield County requires at least two working days' notice before a proposed inspection¹³.

In unincorporated Garfield County, the Garfield County Building Department issues residential and commercial building permits and accepts applications through City Inspect¹. Reach the department at 435-676-1111 or jared.woolsey@garfield.utah.gov¹. Garfield County publishes valuation-based permit fees; residential plan review is $100, manufactured-home permits are charged at 80% of cost, and permit renewal is $100¹⁴. Garfield County will not issue a signed final inspection or certificate of occupancy while code violations remain uncorrected, and it will not perform the final inspection after occupancy¹³. Direct zoning and land-use questions to Planning & Economic Development at 435-676-1157 or kaden.figgins@garfield.utah.gov¹⁵.

Garfield County enforces zoning throughout its unincorporated areas, and Planning & Economic Development manages zoning and subdivision reviews^2,15. Minimum lot size is district-specific; the county's current tables set different requirements for Agriculture, Residential Estates and Residential districts^16,17,18,19. Agriculture and Residential Estates districts use 30-foot front, 10-foot side and 20-foot rear setbacks^17,18. Height and lot coverage also depend on the district: a dwelling in the Agriculture district may not exceed two and one-half stories or 35 feet unless the Planning Commission and Building Official approve it, commercial buildings are limited to 4 stories and 48 feet unless the Planning Commission and Building Official approve an exception, while commercial coverage above 35% needs Planning Commission approval^2,20,21. Septic permits stay with the Southwest Utah Public Health Department regardless of zoning district³. Confirm the parcel's district before relying on any dimensional rule¹⁵.

Southwest Utah Public Health Department handles onsite-wastewater plan review, permits, inspections and records for Garfield County³. Its Garfield County office is at 601 East Center in Panguitch and the main line is (435) 710-5003²². Installing, replacing or modifying a septic system requires a permit and approved design before work begins, and soil and percolation testing must be completed by a Utah-certified onsite professional³. Every septic system needs a final inspection before backfilling; contact Environmental Health to schedule it and keep the project information on site²³. Only 14.1% of county soils are rated without severe limits for a conventional drain field, so make septic feasibility part of the purchase investigation rather than an afterthought⁹.

Garfield County zoning prohibits permanent RV living, defined as occupying a recreational vehicle longer than 30 days in any 60-day period, outside approved and licensed RV parks, subject to stated exceptions⁵. On a developed lot, a temporary hookup to the dwelling's utilities is allowed but permanent occupancy is not; on a vacant lot, permanent utility connections are prohibited⁵. Dry camping under the county's conditional-use standards is limited to 30 consecutive days or less with no permanent water, wastewater or power²⁴. Camping on public land or in a campground also follows that site's posted limits²⁵.

A permanently founded small home may qualify as a primary single-family dwelling in documented Agriculture, Commercial or Resort Recreation districts if it meets building, wastewater and district rules⁶. A small accessory dwelling needs approval from the Building Official and Planning Department, code-compliant water and wastewater, required setbacks, and may not exceed half the main dwelling or 1,000 square feet^7,26. No mobile home may be placed in unincorporated Garfield County without written approval of the County Building Official⁵. Ask Planning & Economic Development to classify the proposal before buying a unit¹⁵.

1. Ask Garfield County Planning & Economic Development to identify the zone, setbacks, lot coverage and whether the use is permitted or conditional^2,15.
2. If creating lots, complete county subdivision review before site preparation or applying for a building permit on a proposed lot²⁷.
3. Confirm water: a valid water right and state Start Card are required before well construction, and a licensed well driller or shallow-well constructor must do the work unless the owner obtains the required license⁸.
4. Complete soil and percolation testing, then obtain the septic permit and approved design from Southwest Utah Public Health Department³.
5. Apply to the Garfield County Building Department through City Inspect and budget from its published fee schedule^1,14. A qualifying sole owner may use the owner-builder licensing exemption, but permit and inspection duties remain⁴.
6. Obtain a UDOT conditional access permit for a driveway connecting to a state highway²⁸.
7. Schedule county inspections, have Environmental Health inspect septic before backfilling, and complete the building final before occupancy^13,23.

Federal ownership covers 91% of Garfield County, so verify the parcel boundary, legal access and any route crossing public land before making an offer⁹. Only 14.1% of county soils are rated without severe limits for a conventional septic drain field, making an early site evaluation especially valuable⁹. Garfield County averages 12.9 inches of precipitation a year and has experienced severe drought in about 32.2% of years, so verify both the water right and physical supply^8,9. The current subdivision rule covers division of unincorporated land into two or more lots; do not assume a deed split creates a buildable parcel²⁷. Before closing, have Planning & Economic Development confirm the zoning district, legal lot status, setbacks, lot coverage, access and whether the proposed dwelling is primary or accessory^2,15.
