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. Fees come from the FY 2027 fee schedule: a valuation table starting at $23.50, plan review of 40% of the permit fee for homes or 65% for other buildings, and a 1% state charge. The office is open Monday to Thursday, 8 a.m. to 5 p.m.
Work inside Lehi city limits. Utah County permits unincorporated areas only and cannot permit a Lehi address.
Solar in Lehi requires two applications, and the power department goes first. Lehi runs its own electric utility, and the city’s solar checklist says every solar application must be approved by the Lehi City Power Department before it is submitted to the Building Department. The plans uploaded for the building permit carry the power department’s approval stamp.
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.
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.

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.
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.
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.

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.

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 | Approved by Lehi City Power before the building submittal | $120 solar inspection fee; interconnection study $350 for 10 to 50 kW |
| Stamped plan hard copy | Every inspection on every project | Contractor prints the approved stamped set for the job site | A site requirement |

| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New commercial construction | Ground-up commercial, industrial, and institutional buildings | Concurrent review against the state-adopted 2024 International Building Code with Utah 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 |

Solar permits in Lehi
Solar is a two-step job in Lehi, and the order matters. File first with Lehi City Power through its solar portal, with the net metering license agreement and the net metering standards application; the power department reviews the same plan set the building permit needs. Then submit the building permit with the power-stamped plans, a one-line diagram, a roof layout showing fire department access, warning labels and their placement, an engineer’s letter on the roof structure, equipment spec sheets and the signed application with the contractor’s licence number.
The FY 2027 fee schedule adds a $120 solar inspection fee on the power side, and systems from 10 to 50 kW pay $350 for an interconnection study ($1,500 above 50 kW). The approved stamped plans must be printed and on site for the inspection.
Installing here? Alliance handles solar permits and the utility interconnection paperwork.
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
Roofing crews can hand this off: Alliance takes care of roofing permit filing through to the issued permit.
Lehi permit cost
Lehi’s building fees are in the FY 2027 fee schedule the city approved with its budget. The permit fee comes from the valuation table below, and the city values work at 90% of the ICC Building Valuation Data (August 2025): its calculator puts a house at $153.72 per square foot of main or second floor, a finished basement at $76.86, an unfinished or semi-finished basement at $38.43, a wood-frame garage at $62.67 and an open carport at $50.14. Plan review and the state charge are percentages of the permit fee.
| Total valuation | Building permit fee |
|---|---|
| $1 to $500 | $23.50 |
| $501 to $2,000 | $23.50 plus $3.05 for each $100 increase |
| $2,001 to $25,000 | $69.25 for the first $2,000 plus $14 for each $1,000 increase |
| $25,001 to $50,000 | $391.75 for the first $25,000 plus $10.10 for each $1,000 increase |
| $50,001 to $100,000 | $643.75 for the first $50,000 plus $7 for each $1,000 increase |
| $100,001 to $500,000 | $993.75 for the first $100,000 plus $5.60 for each $1,000 increase |
| $500,001 to $1,000,000 | $3,233.75 for the first $500,000 plus $4.75 for each $1,000 increase |
| Above $1,000,000 | $5,608.75 for the first $1,000,000 plus $3.65 for each $1,000 increase |
Worked example. Work valued at $300,000 pays $993.75 plus 200 × $5.60, or $2,113.75. Residential plan review at 40% adds $845.50 and the 1% state charge $21.14, for $2,980.39 before impact and connection fees.

|---|---|
| Plan review | 40% of the permit fee for residential work, 65% for non-residential |

New homes also pay impact fees, which the city adopts separately and lists on its impact fee sheet, and connection fees from the FY 2027 schedule. The regional sewer treatment impact fee belongs to the Timpanogos Sanitary Sewer District (renamed from the Timpanogos Special Service District in June 2026); Lehi collects it with the building permit and pays it to the district.
| Fee | Amount |
|---|---|
| Culinary water impact, plus 3/4-inch meter connection | $1,194.07, plus $476.73 |
| Pressurized irrigation impact, plus 1-inch lateral connection | $5,638 per acre (0.25-acre minimum), plus $567.04 |
| Sewer impact | $872.44 |
| Timpanogos Sanitary Sewer District impact fee (regional sewer treatment) | $5,793 per house (since January 23, 2026); $6,171 from January 1, 2027 |
| Storm drain impact | $1,391 per acre (0.25-acre minimum) |
| Transportation impact | $1,219.97 |
| Parks and recreation impact | $2,772.98 |
| Fire/EMT and police impact | $198.02 and $98.35 |
| Power impact and connection, 200-amp single-phase service | $2,554, plus $465.57 |
The city’s August 2026 impact fee sheet still prints the older connection fees ($425.62 for the water meter, $541.66 for the irrigation lateral and $374.02 for 200-amp power); the adopted FY 2027 schedule above is the current one. The district fee is the one in effect on the day Lehi issues the building permit: $5,793 since January 23, 2026 under district Resolution 2026-01, and $6,171 for permits issued from January 1, 2027 under Resolution 2026-11, adopted on September 17, 2026.
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 go to the city rather than an outside utility.
Alliance handles electrical permit expediting for contractors here. More on this: who pulls the electrical permit.
Solar photovoltaic
The clearest example of that. Commercial and residential projects including solar power need Lehi City Power approval, filed through the power department’s own solar portal, before the building permit is submitted.
Plumbing and gas permits
Required for new piping, repipes, fixtures, water heaters and gas piping.
Mechanical permits
Required for furnaces, boilers, air conditioning, heat pumps and ductwork.
Contractors are licensed by the state Division of Professional Licensing, and a business licence must name a qualifier. Utah rules
Lehi application documents
Lehi publishes a checklist for each permit type on the Building and Inspections page. For a new house the list is:
- One complete set of plans: elevations, floor plan, cross sections and details, footing and foundation, electrical, plumbing and mechanical, and the meter base location, service amperage and breaker panel location
- A plot plan dimensioned from the property lines to the building, and front and back elevations
- RESCheck energy compliance, an engineering packet with stamped plans, a gas piping diagram, and Manual J and D load and duct calculations
- The completed application with the contractor’s licence number and signature, a signed hold harmless agreement, and certificates where they apply
Want this handled start to finish?
Get a free quote →A detached garage or shed over 200 square feet needs a floor plan, trade plans if any, a plot plan showing distances from the house and property lines, engineering if necessary, and the application with the contractor’s licence number. Separate sheets cover additions, basement finishes, new commercial buildings, commercial tenant finishes, commercial remodels and signs.
Lehi permit application: how to apply step by step
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.
Submit the solar application, net metering license agreement and standards application through the power department’s solar portal. The building submittal follows, with plans carrying the power department’s stamp.
Title 15A sets the editions. Keep the residential and electrical split straight against the building, plumbing and mechanical codes. Lehi says its current codes and design criteria have changed and will be posted soon; call Inspections at (385) 201-1035 for them.
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. Under the FY 2027 schedule that fee is $100, and the Building Official’s letter adds that the inspectors will not work from punch lists.
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.
Close-out follows the ordinary sequence to the certificate of occupancy once every required inspection has passed.
Utah law lets you use a third-party inspection firm when the building department cannot inspect within three business days. Utah rules

Get a free quote →Frequently asked questions
Do solar projects need anything beyond a building permit?
Yes. Lehi runs its own electric utility, and every solar application must be approved by the Lehi City Power Department, through its solar portal, before it goes to the Building Department. The building plans then carry the power department’s approval stamp.
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.
How much is a building permit in Lehi?
It depends on the valuation. Under the FY 2027 schedule, $100,000 of work pays $993.75 and each further $1,000 up to $500,000 adds $5.60; residential plan review adds 40% of that fee and the state charge 1%. Work valued at $300,000 comes to $2,980.39 with plan review and the state charge.
What impact fees does a new house pay in Lehi?
The city’s sheet updated on August 26, 2026 lists, among others, $1,194.07 for culinary water, $872.44 for sewer, $1,219.97 for transportation, $2,772.98 for parks, plus pressurized irrigation and storm drain fees per acre and power fees by service size. The Timpanogos Sanitary Sewer District’s regional sewer fee is $5,793 per house for permits issued since January 23, 2026 and $6,171 from January 1, 2027.
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 before 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.
