Building permits in unincorporated Tooele County are issued by Building and Development Services. The county covers a very large area west of the Oquirrh Mountains, much of it rural and much of it without public utilities.
This guide covers the site plan the county actually wants and why wells and septic have to be on it, the licensed architect requirement on commercial work, the fire protection criteria to read before applying, the recently adopted impact fees, and how the statewide codes apply.
This guide covers unincorporated Tooele County. Tooele City and Grantsville run their own arrangements.
Your site plan has to show the wells and septic systems, with distances. The county requires a site plan showing property size, the location and distances of existing buildings, wells and septic systems, and the proposed structure — because zoning officers verify setbacks from property lines and from wells and septic, while the building department checks required separation of buildings on the lot.
What requires a permit in Tooele County?
Tooele County Building and Development Services issues building permits for the unincorporated county. Tooele City, Grantsville, Stansbury Park's surrounding communities and the county's other municipalities handle their own arrangements. The county covers a very large area west of the Oquirrh Mountains, much of it rural and much of it without public utilities.
The permit trigger is stated broadly and the county attributes it to both levels of government: state and county laws require that anyone who wants to construct, enlarge, alter, repair, move, demolish or change the use of any building or structure must first get a permit, and that includes work on electrical, plumbing, gas or mechanical systems. There are exceptions, and the county asks that you call the inspectors to confirm rather than assume.
Utah does something most western states do not: it adopts one construction code for the entire state. The State Construction and Fire Codes Act in Title 15A of the Utah Code sets the adopted editions, and they apply in every city, town and county rather than being chosen jurisdiction by jurisdiction. That means the question a designer has to answer here is not which edition does this city use — it is the same edition everywhere — but which local amendments, zoning standards, fire authority and service district apply on top of it.
There is a split in the current adoption that matters on every project, and getting it backwards is the most common Utah code error. Effective the first of July twenty twenty-six, Utah moved the building, plumbing, mechanical, fuel gas, energy conservation, existing building and swimming pool and spa codes to their twenty twenty-four editions. The residential code did not move — it remains the twenty twenty-one edition — and the electrical code remains the twenty twenty-three edition. So a commercial building is designed to a twenty twenty-four code while the house next door is still on twenty twenty-one, and both are correct.
Permit required
- Constructing, enlarging, altering, repairing, moving or demolishing a building
- Changing the use of any building or structure
- Electrical, plumbing, gas and mechanical system work
- New residential and commercial construction and additions
- Work on parcels served by wells and septic systems
- Solar photovoltaic systems and battery storage
- Projects triggering the county's impact fees
- Commercial projects, which require a licensed architect
Typically exempt
- Work the county identifies as exempt — call the inspectors to confirm
- Purely cosmetic finish work that alters no regulated system
- Like-for-like minor repairs not affecting structure or a system
- Routine maintenance that does not extend or reroute a system
Tooele County building department: who handles permitting
The county publishes a permit application together with a general instructions document, and asks something specific of applicants: review the fire protection criteria at the end of the general instructions before applying. That is an unusual and helpful instruction — fire protection requirements on a rural parcel can turn on water supply and access, and discovering them after design is fixed is expensive.
The submittal expectations are set out plainly. Alongside the completed application and site plan, the county wants proof of ownership or permission to build on the property, and construction documents described as a complete set of plans with enough information to show the structural and physical elements of the project. Any commercial project will need to be prepared by a licensed architect, and some elements of residential construction may need to be engineered — the county says the inspectors can help identify which.
Impact fees changed recently. The county adopted an impact fee ordinance in twenty twenty-four creating new impact fees effective from December of that year. On a new dwelling or a commercial project those are a material budget line separate from the permit fee, so confirm the current schedule rather than working from an older figure.

Read the fire protection criteria before you apply, not after. The county publishes them at the end of its general instructions document and specifically asks applicants to review them to ensure compliance prior to applying for a building permit. On rural parcels fire protection turns on water supply, access and separation — all of which are site design decisions, not details you can add to a finished drawing set.
Tooele County is not Tooele City. The county and its largest city share a name, and the county serves the unincorporated remainder while Tooele City and Grantsville run their own arrangements. The county also contains substantial federal land — including major military installations — which sits outside county building jurisdiction entirely. Confirm the land status as well as the jurisdiction.
Tooele County permits: record types and what each covers
The record catalog is the rural Utah set, with the site plan and the wells and septic picture doing more work here than the building permit itself on many parcels.
Residential permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures above the local size threshold | Plan review against the jurisdiction's adopted residential code and local amendments, plus zoning and setbacks | Valuation-based |
| Addition | Added conditioned or unconditioned space attached to an existing dwelling | Structural and energy review; Utah spans several climate zones from the low desert to the high Wasatch, so envelope and equipment sizing draw attention | Valuation-based |
| Renovation / alteration | Structural changes, layout changes, or added plumbing, mechanical, or electrical | Plan review scaled to scope; a change that alters egress, structure, or a system is reviewed even where the footprint does not move | Valuation-based |
| Reroof | Roof covering replacement, recover, and structural deck repair | Deck and dry-in inspection; plan review rarely required, but a change of assembly type can trigger a structural check | Valuation or squares |
| Solar photovoltaic | Rooftop or ground-mount arrays, with or without battery storage | Single local review covering both the structural attachment and the electrical scope; there is no separate state electrical record in Utah | Flat or system-size based |
| Battery energy storage | Wall or floor-mounted storage added to a dwelling | Electrical review plus fire separation, ventilation, and location check | Flat or per-permit minimum |
| Electrical | Service changes, panel upgrades, new circuits, EV chargers, meter sets, and rewiring | Local trade review and local inspection against the National Electrical Code edition the jurisdiction has adopted | Per-permit or per-device |
| Plumbing | New piping, repipes, fixtures, gas piping, and water heater replacement | Local trade review; performed by a contractor holding the matching state licence classification and qualifier | Per-permit minimum or per-fixture |
| Mechanical / HVAC | Changeouts, new ductwork, and refrigeration | Local trade review; changeout volume is heavy given Utah heating loads and wide seasonal swings | Per-permit minimum or per-unit |
| Patio cover and shade structure | Attached and detached covers, ramadas, and carports | Structural review for wind uplift and attachment, plus zoning for setbacks and lot coverage | Valuation or flat |
| Swimming pool | In-ground and above-ground pools and spas | Barrier, bonding, and electrical review; the statewide adopted pool and spa code applies on top of local rules | Valuation or flat |
| Manufactured home set-up | Placing or re-siting a manufactured or modular home | State-level manufactured housing approval, with local zoning, floodplain, foundation, and utility connection review | Flat or per-unit |
| Demolition | Full or partial demolition of a dwelling or accessory structure | Utility disconnect confirmation, dust control where earthmoving is involved, and site restoration check | Flat |
| Site plan with wells and septic | Any rural parcel with on-site systems | Locations and distances required; setbacks are measured from them | Part of the submittal |
| Proof of ownership | Every application | Ownership or permission to build on the property | Part of the submittal |
Commercial permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New commercial construction | Ground-up commercial, industrial, and institutional buildings | Concurrent review against the jurisdiction's adopted building code and amendments, plus fire and zoning | Valuation-based |
| Tenant improvement / upfit | Interior fit-out of an existing tenant space | Building, trade, and life-safety review; accessibility attaches on change of use | Valuation-based |
| Change of occupancy | Converting a building or space to a different use group | Occupancy classification, egress, and accessibility review | Valuation or flat |
| Commercial electrical | Service, distribution, and branch circuit work | Local trade review and local inspection; Utah has no central state electrical permit for either residential or commercial work | Per-permit or valuation |
| Commercial plumbing | Process piping, fixtures, backflow, and grease waste | Local trade review; backflow and grease interceptor sign-off where applicable | Per-fixture or valuation |
| Commercial mechanical | Rooftop units, kitchen exhaust and hood systems, and refrigeration | Local trade review; hood and suppression systems draw fire review alongside mechanical | Per-unit or valuation |
| Commercial reroof | Roof covering replacement on a commercial structure | Deck, dry-in, and attachment inspection | Valuation or squares |
| Signage | Wall, ground, and illuminated signs | Zoning review for size and placement, plus electrical where illuminated | Flat or per-sign |
| Grading and drainage | Clearing, grading, and site work that alters drainage | Civil review of grading and drainage, separate from the building permit; monsoon-season flows drive the design | Acreage or valuation |
| Dust control permit | Earthmoving, trenching, and construction dust on a qualifying site | County air quality department, not the building department; required in the fine-particulate nonattainment areas | County air quality fee schedule |
| Commercial demolition | Full or partial demolition of a commercial structure | Utility disconnect, asbestos notification, dust control, and site restoration | Flat or valuation |
| Architect-prepared plans | Any commercial project | The county requires plans prepared by a licensed architect | A design cost |
| Impact fees | New dwellings and commercial projects | New fees adopted in twenty twenty-four, effective that December | Confirm the schedule |

Solar permits in Tooele County
Solar is reviewed on two tracks in Utah, but unlike some neighbouring states both tracks belong to the same government. The structural side — attachment detail, rail spacing, and whether the existing framing carries the added dead load — and the electrical side — conductors, overcurrent protection, rapid shutdown, labelling, and the service or supply-side connection — are both permitted and inspected by the local Authority Having Jurisdiction. There is no state electrical record to buy alongside the local one, and no state inspector to book.
Solar in unincorporated Tooele County is permitted and inspected by the county under Utah's statewide adopted editions. The Utah rule governing every trade here is the edition split: the building, plumbing, mechanical, fuel gas and energy codes moved to their twenty twenty-four editions in July twenty twenty-six, while the residential code stayed on twenty twenty-one and the electrical code on twenty twenty-three. Reading the building code year and inferring the electrical year gets rapid shutdown, labelling and conductor requirements wrong. On a rural parcel the site plan requirements bite here too: the county wants existing buildings, wells and septic located with distances, and a ground-mounted array is a structure whose position interacts with all of them. Tooele Valley snow load is a genuine structural input.
What does NOT vary here is the code edition. Because Utah adopts one and county adopts its own editions on its own timetable, the National Electrical Code edition your array is judged against in one jurisdiction may not be the one enforced a few miles away. The Office of the State Fire Marshal sets a minimum electrical standard for the state, but the edition actually enforced is the local one. Confirm it with the jurisdiction before the design is finalised rather than after a correction notice.
Interconnection runs on a third clock and is not something the building department controls. Utah properties are served by utilities including Rocky Mountain Power and a number of municipal electric systems, and UniSource, alongside municipal utilities and irrigation districts, and each sets its own application, meter and witness-test sequence. Permission to operate follows the utility's process on the utility's schedule, so plan for the tracks to finish at different times.
Roofing permits in Tooele County
A roof covering replacement needs a permit in most Utah jurisdictions, and the assumption that a like-for-like replacement is exempt travels badly here. The permit is usually quick, but the inspection that matters happens before the covering goes on rather than after.
Utah operates no statewide product-approval database, so there is no approval number to search for or cite on the application. The assembly has to comply with the edition of the code the jurisdiction has adopted and with the manufacturer's listed installation instructions, and that pairing is what the inspector checks — which makes the manufacturer's instructions a document worth having on site.
A roof covering replacement is permitted work — the county's trigger language captures repair and alteration explicitly, not just new construction. Tooele Valley carries real winter weather, so roofing is designed against snow load and freeze-thaw. Distance is the scheduling constraint: the county is geographically enormous, so give generous notice and make access easy.
Two Utah-specific pressures shape the work. Snow load at elevation and ultraviolet exposure age a covering faster than the same assembly would age in a milder climate, and monsoon-season wind and driven rain test the fastening and the flashing details rather than the field of the roof. Sequencing is where reroofs go wrong regardless: the deck and dry-in condition has to be visible when the inspector arrives, so covering it first means opening it back up.
Tooele County permit cost
Permit fees follow the county's adopted schedule, with building fees valuation-driven and plan review assessed alongside, and trade permits charged per discipline.
Impact fees are the line most likely to move a Tooele County budget. The county adopted a new impact fee ordinance in twenty twenty-four with fees effective from that December, so any figure from before then is stale. On a rural parcel add the design costs the county's own requirements imply: an architect on any commercial project, engineering on some residential elements, and well and septic siting work. Utah jurisdictions commonly double permit fees where work has been started or completed without a permit, and several publish that rule explicitly. Treat it as the default expectation rather than an unusual penalty.
| Fee component | How it works |
|---|---|
| Building permit fee | Valuation-based under the county's adopted schedule |
| Plan review | Assessed alongside the building permit |
| Impact fees | New fees adopted in twenty twenty-four; confirm the current schedule |
| Architect | Required on any commercial project; a design cost |
| Residential engineering | Where the inspectors identify elements needing it |
| Septic and well work | Separate scopes on parcels without utility service |
| Trade permits | Electrical, plumbing, mechanical and gas per discipline |

Tooele County trade permits
The trades are permitted and inspected by the county under Utah's statewide adopted editions, and the county states explicitly that electrical, plumbing, gas and mechanical work is captured by the permit requirement.
Electrical permits
Required for service changes, panel work, new circuits, solar and EV charging. Utah's adopted electrical code did not move in the twenty twenty-six transition, so confirm the edition rather than inferring it from the building code year.
Plumbing and gas permits
Required for new piping, repipes, fixtures, water heaters and gas piping. On the county's rural parcels the plumbing scope connects to a septic system and often a private well, both of which have to appear on the site plan with distances.
Mechanical permits
Required for furnaces, boilers, air conditioning, heat pumps and ductwork. Tooele Valley carries a real heating load, and parcels in the higher country west and south of the valley more so again.
Site design and fire protection
Not a trade, but the discipline that shapes a rural Tooele County project. Well and septic separation distances constrain where a building can sit, and the county's fire protection criteria — published at the end of its general instructions — turn on water supply and access.
Tooele County permit application: how to apply step by step
Here is how to get a building permit in Tooele County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Tooele City and Grantsville run their own arrangements, and substantial federal land in the county sits outside county building jurisdiction entirely.
They are published at the end of the county's general instructions document, and the county asks that you review them to ensure compliance before applying.
Property size, existing buildings, wells and septic systems with distances, and the location of the proposed structure — because setbacks are measured from all of them.
Any commercial project must be prepared by a licensed architect, and some residential elements may need engineering. The inspectors can help identify which.
The county adopted a new impact fee ordinance in twenty twenty-four with fees effective that December. Older figures are stale.
Submit the completed application with the site plan, proof of ownership or permission to build, and the construction documents, then work the inspection sequence to close-out.
Inspections in Tooele County
Inspections are requested through the county's process against the issued permit. The county invites applicants to call the inspectors to confirm whether a permit is needed at all, which is a sensible offer in a jurisdiction where the exemptions are real but not exhaustively published — use it rather than guessing.
Utah gives applicants something most states do not: a route around a slow inspection queue. Under the state construction code provisions, where the jurisdiction cannot complete a requested inspection within three business days of receiving the request, inspection may be carried out by a third-party inspection firm the jurisdiction has contracted with. Some jurisdictions run the parallel route instead, entering mutual aid agreements with neighbouring cities to perform inspections when they cannot meet the same three-day standard. The procedure matters as much as the right, and skipping a step voids it. You must notify the jurisdiction before contacting a third-party inspector, and the third-party inspection is not authorised until two things have happened: the jurisdiction has confirmed it cannot complete a timely inspection itself, and you have told it you intend to use the third party. Where the route runs through a mutual aid agreement instead, use of the neighbouring jurisdiction has to be arranged with the local building inspectors first. An inspection obtained without that sequence is not a valid inspection.
Distance is the practical constraint here. Tooele County is geographically enormous, running west from the Oquirrh Mountains across the valley and out toward the desert, so inspector travel to a remote parcel consumes a large part of a working day. Give generous notice, make sure the work is genuinely ready, and make access straightforward.
Close-out follows the ordinary sequence to occupancy once every required inspection has passed. On a rural parcel expect the septic approval and any fire protection conditions to be part of getting there rather than separate errands.

Frequently asked questions
When do I need a permit in Tooele County?
The county states that state and county laws require a permit before constructing, enlarging, altering, repairing, moving, demolishing or changing the use of any building or structure, including work on electrical, plumbing, gas or mechanical systems. There are exceptions, and the county asks you to call the inspectors to confirm.
What has to be on my site plan?
The size of the property, the location and distances of any existing buildings, wells and septic systems, and the location of the structure you intend to build. Zoning officers use it to verify setbacks from property lines, wells and septic systems, and the building department uses it to check required separation of buildings on the lot.
Do I need an architect?
On any commercial project, yes — the county states it must be prepared by a licensed architect. Some elements of residential construction may also need to be engineered, and the county says the inspectors can help identify which.
What are the fire protection criteria?
Requirements published at the end of the county's building permit application and general instructions document. The county asks specifically that you review them to ensure compliance prior to applying for a building permit — on rural parcels they turn on water supply and access.
Have impact fees changed?
Yes. The county adopted an impact fee ordinance in twenty twenty-four creating new impact fees effective from December of that year. Any figure from before then is stale, so confirm the current schedule.
What else do I need to submit?
A completed permit application, the site plan, proof of ownership or permission to build on the property, and construction documents described as a complete set of plans with enough information to show the structural and physical elements of the project.
Which codes apply?
Utah's statewide adopted editions under Title 15A. The building, plumbing, mechanical, fuel gas, energy, existing building and pool codes moved to twenty twenty-four editions in July twenty twenty-six; the residential code remains twenty twenty-one and the electrical code twenty twenty-three.
Is Tooele County the same as Tooele City?
No. They share a name, and the county serves the unincorporated remainder while Tooele City and Grantsville run their own arrangements. The county also contains substantial federal land that sits outside county building jurisdiction entirely.
What if the county cannot inspect in time?
Utah's state construction code provisions allow a third-party inspection where the jurisdiction cannot complete a requested inspection within three business days. Notify the jurisdiction first — it is not authorised until the jurisdiction confirms it cannot inspect and you have said you intend to use the third party.
Does distance affect inspections?
In practice, yes. Tooele County is geographically enormous, so inspector travel to a remote parcel consumes a large part of a working day. Give generous notice, be genuinely ready, and make access straightforward.
Do I need fire sprinklers in a new house?
Not by force of the state residential code, which Utah amended to remove the model requirement for automatic sprinklers in new one- and two-family dwellings and townhouses. The county's own fire protection criteria are a separate matter and do apply.
Does my permit affect lien rights?
Yes. The jurisdiction issuing a building permit must transmit the permit information to the State Construction Registry within fifteen days, and that information forms the basis of the notice of commencement.
