Building permits in Washington County, Utah usually start with Washington County Community Development for unincorporated or county-served work, but city permit departments may control projects inside incorporated municipalities.
This guide covers what requires a permit, how to apply through Online permitting software or the correct local filing path, permit fees, Utah trade permits, DOPL contractor licensing, fire review, and inspections - so your Utah project can move from submittal to approval with fewer correction cycles.
Confirm the authority having jurisdiction before filing. This guide is for projects in unincorporated Washington County; St. George, Washington City, Hurricane, Ivins, Santa Clara, and other municipalities may issue separate permits. Utah projects can split among city building departments, county or MSD service areas, local fire authorities, the Utah State Fire Marshal, public works, health departments, utility providers, highway agencies, floodplain administrators, and special districts depending on scope and location.
Utah uses statewide construction and fire codes with amendments. Utah building permits are governed by the Utah State Construction and Fire Codes Act, Utah Code Title 15A, with statewide construction and fire code amendments plus local zoning, fire, public works, utility, stormwater, floodplain, historic, and development standards. Utah is in a 2026 code-cycle transition: Title 15A lists 2021 I-Codes and the 2023 NEC for the pre-July 2026 cycle, and effective July 1, 2026 adopts several 2024 I-Code editions, including the 2024 IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC, while retaining the 2021 IRC and 2023 NEC. Always verify the active code edition and local amendments with the permit authority before filing.
Washington County projects often involve rapid-growth subdivisions, desert drainage, wildfire interface, geotechnical issues, septic or utility approvals, fire access, impact fees, and city/county boundary checks around St. George and nearby communities.
What requires a building permit in Washington County?
Under Utah Title 15A, adopted model codes, and local ordinances, a permit is required before most construction, alteration, demolition, repair, relocation, occupancy change, and trade work begins.
Permit required
- New residential and commercial construction, additions, remodels, basement finishes, and tenant improvements
- Structural changes, load-bearing work, foundations, decks, porches, retaining walls, garages, and accessory buildings above local thresholds
- Electrical service changes, panels, generators, solar, EV chargers, new circuits, and most wiring
- Plumbing, water heaters, sewer and water connections, gas piping, backflow, and fixture relocations
- HVAC installations, furnace or AC replacements, ductwork, ventilation, make-up air, and fuel-gas appliances
- Roofing, siding, windows, signs, pools, demolition, grading, erosion control, fire systems, and right-of-way work where regulated
Typically exempt
- Painting, wallpaper, flooring, trim, cabinets, countertops, and similar finish work
- Minor repairs replacing existing materials in kind with no structural, electrical, plumbing, mechanical, or fire-system change
- Small detached accessory structures below local size thresholds when allowed by zoning and without utilities
- Portable equipment or temporary work that the local code specifically exempts
Exemptions are narrow and local. Always verify with the building inspector or permit counter before starting work.
Get the permit before work begins. Starting without approval can lead to stop-work orders, double fees, correction orders, delayed occupancy, and problems with resale, financing, or insurance.

Washington County trade permits
Trade permits are commonly required in addition to the building permit. Utah DOPL licensing, contractor classifications, master qualifiers, local business licensing, and inspection requirements may apply depending on scope and jurisdiction.
Electrical permits
Required for service upgrades, panels, new circuits, solar PV, EV chargers, generators, lighting retrofits, tenant improvements, and most wiring work. Electrical contractors must meet Utah licensing and qualifier requirements.
Plumbing & gas permits
Required for new plumbing, fixture relocations, water heaters, sewer and water connections, backflow, gas piping, fuel-gas appliances, medical gas, and private or public utility connections where applicable.
Mechanical / HVAC permits
Required for furnaces, boilers, AC units, heat pumps, ductwork, commercial kitchen hoods, ventilation, combustion air, exhaust, and major equipment replacements.
Fire, occupancy, and specialty permits
Commercial projects may require fire alarm, sprinkler, suppression, hood, hazardous-material, LP gas, sign, demolition, right-of-way, grading, erosion control, temporary use, and certificate of occupancy approvals before final use.
Credential check: Utah contractors are licensed through the Utah Department of Commerce Division of Professional Licensing. General contractors, residential contractors, building contractors, electrical contractors, plumbing contractors, HVAC, roofing, fire-protection, and specialty scopes may require the correct DOPL license classification, qualifier, insurance, business registration, workers compensation compliance, pre-licensure education, and local business-license registration before a permit can be issued. Electrical and plumbing contractor classifications may require a master electrician or master plumber qualifier.
Fire review: The Utah State Fire Marshal handles licensing for certain fire/life-safety industries and plan-review responsibilities for state-owned buildings, schools, hospitals, and other state-fire-marshal scopes, while local fire authorities review many city and county projects. Fire alarm, sprinkler, hood suppression, hazardous materials, LP gas, access, hydrants, and occupancy approvals can run alongside the building permit.
