Building permits in Lehi are handled and issued by the Building and Inspection Department at 153 North 100 East (385-201-1035), which employs certified inspectors who are qualified plan examiners; applications go through the city’s iWorQ Building Permit Submittal Portal. Lehi sits at the northern end of Utah County along the technology corridor and has been among the state’s fastest-growing cities for two decades.
This guide covers the electronic submittal portal and what must go through it, the second application solar projects owe to the city's own power department, the stamped-plans-on-site rule, the inspection notice and re-inspection policy, and how the statewide codes apply.
This guide covers work inside Lehi city limits. Utah County permits unincorporated areas only and cannot permit a Lehi address.
Solar in Lehi requires two applications, not one. The city states that commercial and residential projects including solar power must also submit an application to the Lehi City Power Department. Lehi runs its own municipal electric utility, so interconnection approval comes from another city department and is a separate filing. An installer who files only the building permit has done half the job.
What requires a permit in Lehi?
The Lehi City Building and Inspection Department handles and issues all building permits for Lehi. The city employs certified inspectors who are qualified plan examiners and inspectors across all types of building construction. Lehi sits at the northern end of Utah County along the technology corridor, and it has been among the fastest-growing cities in the state for two decades.
All permit applications must be submitted through the Building Permit Submittal Portal, and all plans are to be submitted electronically. That includes permit applications, compliance checks, structural documents and geotechnical reports — the city names geotech explicitly, which is worth noting because it is often treated as a supporting document filed later rather than part of the submittal.
Permit required
- New residential and commercial construction, additions and remodels
- Structural alterations, relocation and demolition
- Solar power projects, which also require a city power application
- Electrical service changes, panel work and new circuits
- Plumbing, gas piping, water heaters and fixture work
- Mechanical installations and equipment replacements
- Work requiring geotechnical reports, submitted with the plans
- Re-roofing and exterior envelope work
Typically exempt
- 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
- Work the city's published guidance identifies as exempt
Utah adopts one construction code for the whole state; cities and counties enforce it, and any local amendments are set by the Legislature. Utah rules
Lehi building department: who handles permitting
Reviews are digital and the approved plans are stamped on every page. The city stamps each page so inspectors can confirm they are looking at the current approved sheets, and contractors are responsible for printing a hard copy of the approved stamped plans and having them on the job site for every inspection. Working from a tablet or an unstamped set is not compliance with that rule.
Inspection policy is stated plainly. Allow 24 hours' notice for any type of inspection, and book it by calling the Building Inspection Office at 385-201-1035; the city does not schedule inspections by voicemail, email or online. The city also asks applicants to help it conduct inspections efficiently by ensuring the project is ready before scheduling — noting that re-inspection fees will be assessed when a project is clearly not ready. That is a fair warning rather than a trap, and it rewards discipline in a city where inspector demand is high.
Inspection status is publicly checkable online, which is useful on a busy site — but the lookup only reports status; it does not book an inspection. Developers and contractors can look up inspection status using the building permit number, the site address, or the subdivision and lot number — the last of which is genuinely helpful on a production subdivision where the permit number may not be to hand.

Print the stamped set and leave it on site. Lehi reviews plans digitally and stamps each page so inspectors can check they are working from current approved sheets — and the city puts the responsibility on the contractor to print a hard copy of the approved stamped plans and have them on the job site for every inspection. An inspector arriving to find no stamped hard copy has a reason to fail the visit before looking at the work.
Lehi is not Utah County, and it is not Saratoga Springs or Eagle Mountain. Utah County’s Building Division serves unincorporated areas only and cannot permit a Lehi address. Saratoga Springs, Eagle Mountain, American Fork, Highland, Alpine and Draper all border or sit near Lehi and each permits its own work — and Draper lies mostly in Salt Lake County, with a small part in Utah County. Confirm from the parcel.
In 2025, building permits issued in Lehi authorized 1,133 new privately owned housing units, 829 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Lehi permits: record types and what each covers
The record catalog is conventional with one important addition: in Lehi the power department is part of the permitting picture rather than an outside utility.
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 state-adopted 2021 International Residential Code with Utah amendments, plus zoning and setbacks | Valuation-based |
| Addition | Added conditioned or unconditioned space attached to an existing dwelling | Structural and energy review; since 1 July 2026 houses follow Utah's own energy chapter in the residential code, with one set of insulation values statewide | 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 2023 National Electrical Code, which applies statewide | 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 state code adopts the residential provisions of the 2024 International Swimming Pool and Spa Code | Valuation or flat |
| Manufactured home set-up | Placing or re-siting a manufactured or modular home | Federal HUD label for manufactured homes or a state decal for modular units, 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 |
| City power solar application | Any project including solar power | Required in addition to the building permit | A separate filing |
| Stamped plan hard copy | Every inspection on every project | Contractor prints the approved stamped set for the job site | A site requirement |

Solar is the headline here, and it is a two-filing job: the building permit plus an application to the Lehi City Power Department, because the city owns its electric utility. Start both together rather than treating interconnection as a post-approval formality. Confirm applicable code editions and design criteria with Lehi Building and Inspections before finalising plans; the building application does not replace the separate Lehi City Power application. Utah Valley snow load is a real structural input on the roof attachment, and the approved stamped plans must be printed and on site for the inspection.
Interconnection is not something the building department controls. Solar projects also require a separate application to Lehi City Power, which runs its own solar process; a building application does not replace that step, so plan for the building permit and the power approval to finish at different times.
Roofing permits in Lehi
A roof covering replacement is permitted work and follows the ordinary sequence. Two Lehi rules apply to the visit: allow 24 hours' notice for any type of inspection, and have the printed stamped approved plans on site. Re-inspection fees are assessed when a project is clearly not ready, so request only when it genuinely is.
Solar and roofing work follow the statewide code, and utilities run interconnection on their own timeline. Utah rules
Lehi permit cost
Permit fees follow the city's adopted schedule, with building fees valuation-driven and plan review assessed alongside, and trade permits charged per discipline. Re-inspection fees are assessed where a project is clearly not ready when the inspection is requested.
The cost specific to Lehi that catches solar contractors is the second filing with the city power department. Budget it as a separate application with its own timeline rather than assuming interconnection runs in parallel with the building permit automatically. 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 city's adopted schedule |
| Plan review | Assessed alongside the building permit |
| Trade permits | Electrical, plumbing, mechanical and gas per discipline |
| City power application | A separate filing for any project including solar |
| Re-inspection fee | Assessed when a project is clearly not ready |
| Geotechnical report | A design cost, submitted electronically with the plans |
| Impact fees | Assessed separately where the project triggers them |

Lehi trade permits
The trades are permitted and inspected by the city under Utah's statewide adopted editions — and the electrical picture here is distinctive because the city owns the utility.
Electrical permits
Required for service changes, panel work, new circuits, solar and EV charging. Because Lehi runs its own power department, service and metering questions are a city matter rather than an outside utility matter — which usually helps, but means the city is on both sides of the connection.
Solar photovoltaic
The clearest example of that. Commercial and residential projects including solar power must also submit an application to the Lehi City Power Department alongside the building permit. Treat it as a parallel filing from day one rather than a post-approval formality.
Plumbing and gas permits
Required for new piping, repipes, fixtures, water heaters and gas piping. Lehi's growth means a large share of the housing stock is recent, so the workload skews toward new construction rather than repipe.
Mechanical permits
Required for furnaces, boilers, air conditioning, heat pumps and ductwork. Utah Valley carries a genuine heating load alongside summer cooling, so equipment sizing is a two-sided calculation.

Lehi permit application: how to apply step by step
Here is how to get a building permit in Lehi, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Utah County cannot permit a Lehi address, and Saratoga Springs, Eagle Mountain, American Fork, Highland and Alpine each permit their own.
All applications go through the Building Permit Submittal Portal and all plans are submitted electronically, including compliance checks, structural documents and geotechnical reports.
Commercial and residential projects including solar power must also submit an application to the Lehi City Power Department. Start it alongside the building permit, not after.
Title 15A sets the editions. Keep the residential and electrical split straight against the building, plumbing and mechanical codes, and confirm current code editions and design criteria with Lehi Building and Inspections before finalising plans.
Reviews are digital and plans are stamped on each page. The contractor is responsible for having a hard copy of the stamped set on site for every inspection.
Schedule by calling the Building Inspection Office at 385-201-1035 with at least 24 hours' notice for any type of inspection; the city does not schedule inspections by voicemail, email or online. Make sure the project is genuinely ready — re-inspection fees are assessed when it clearly is not.
Inspections in Lehi
Inspections are booked by calling the Building Inspection Office at 385-201-1035 with 24 hours' notice for any type; the city does not schedule them by voicemail, email or online. The city is also direct about readiness: re-inspection fees will be assessed when a project is clearly not ready. In one of Utah's fastest-growing cities, inspector capacity is the constrained resource, and the policy is a reasonable response to it.
Status is checkable online, though booking an inspection still takes a phone call. Developers and contractors can look up inspection status using the building permit number, the site address, or the subdivision and lot number — the last being particularly useful on a production subdivision where a superintendent may know the lot but not the permit number.
Close-out follows the ordinary sequence to the certificate of occupancy once every required inspection has passed. On a solar project confirm the city power side is complete as well — a passed electrical inspection is not the same as an approved interconnection.
Utah law lets you use a third-party inspection firm when the building department cannot inspect within three business days. Utah rules

Frequently asked questions
Do solar projects need anything beyond a building permit?
Yes. The city states that commercial and residential projects including solar power must also submit an application to the Lehi City Power Department. Lehi runs its own municipal electric utility, so interconnection is a second city filing rather than an outside utility process.
How do I submit plans?
Electronically, through the Building Permit Submittal Portal. All plans are submitted that way, including permit applications, compliance checks, structural documents and geotechnical reports.
Do I need the approved plans on site?
Yes, as a printed hard copy. Reviews are done digitally and plans are stamped on each page so inspectors can check for current approved sheets, and contractors are responsible for printing the stamped set and having it on the job site for every inspection.
How much notice do inspections need?
At least 24 hours for any type of inspection, booked by calling the Building Inspection Office at 385-201-1035; the city does not schedule inspections by voicemail, email or online. The city also asks that you ensure the project is ready before scheduling, and states that re-inspection fees will be assessed when a project is clearly not ready.
Can I check inspection status without calling?
Yes. Developers and contractors can check inspection status using the building permit number, the site address, or the subdivision and lot number — the last being useful on a production subdivision. The lookup does not book inspections; those are still scheduled by phone on 385-201-1035.
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 2024 editions in July 2026; the residential code remains 2021 and the electrical code 2023.
Can Utah County permit my Lehi project?
No. Utah County’s Building Division serves unincorporated areas only. Lehi permits its own work, as do Saratoga Springs, Eagle Mountain, American Fork, Highland and Alpine. Draper, just north, lies mostly in Salt Lake County and permits its own work too.
What if the city cannot inspect in time?
Utah law lets you use a third-party inspection firm when the city or county cannot inspect within three business days of your request. Pick a firm from the building department's approved list and tell the building department which firm you will use before you hire it.
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. Local fire requirements can still apply.
Does my permit affect lien rights?
Yes. A city, town or county that issues a building permit for a private project must send the permit information to the State Construction Registry within 15 days, and the contractor must post a copy of the permit at the site.
What happens if I build without a permit?
Utah jurisdictions commonly double permit fees for work started or completed without a permit, and several publish that rule explicitly. Treat it as the default expectation.
Do I need a licensed contractor?
In almost all cases. Utah licenses contractors through the Division of Professional Licensing, and a business licence must name a qualifier. The licence is valid statewide; besides it, state law requires only a business licence from the city or county where the contractor's main office is.
Simplify Lehi permitting with Alliance Permitting
Lehi is a fast, well-organised department with one requirement that catches almost every out-of-town solar contractor — the second application to the city's own power department. Alliance Permitting prepares, files and tracks Lehi permits through issuance.
Trusted by leading builders, developers, and national contractors — 21+ years of filing in the jurisdictions we write about.
Contractors and builders choose Alliance for Lehi because the work is done by people who have stood at the counter:
- We file the city power application alongside the building permit on every solar project.
- We submit geotechnical reports with the plan set, as the city's electronic rule requires.
- We make sure the stamped hard copy is on site before an inspector is ever booked.
- We request inspections only when the project is genuinely ready, since re-fees are policy here.
Alliance Permitting is a permit documentation and expediting service in Utah. We are not a law firm and do not provide legal advice, and we are not the permitting authority.
