The short answer
Salt Lake City answers this job's paperwork question the strict way. The city's Building Services says permits are required to replace exterior windows, with a window schedule filed for each swap, even when the new window is the same size as the old one. The money has its own local shape: most homes here sit on two meters, and each utility pays by a different formula. Rocky Mountain Power's Utah tariff lists windows at up to $50 apiece; ThermWise, the gas program, pays $2.50 per square foot of glass for U-values of 0.22 or lower. Below: the permit path, the area where the two rebates swap places, who may legally install windows in Utah, what 4,327 feet of altitude does to sealed glass, and why the four big suburbs need their own phone call.

The permit: every window, every time
The city's Building Services and Code Enforcement FAQ does not hedge. Asked whether a permit is needed to replace doors or windows, it answers that permits are required to replace exterior doors or windows, and that a window schedule has to be completed and submitted for plan review. The schedule lists the size and type of each window being added or replaced and the room it serves. Compare the neighbors we mapped: Seattle, Charlotte and Dallas let a same-size swap go without one (see our Dallas guide for the contrast). In Salt Lake City, the cheap-looking "we just swap the glass" bid that skips paperwork is the one that should worry you.
The window schedule, and its dated form
The city's Window & Door Schedule asks, per window, for the room, the room size, the window size, how it opens, the net clear egress area, whether the glass is tempered and the sill height, plus a flag when the wall holding the window sits less than three feet from a property line. It also carries the reminder that tempered glass is required near doors, tubs and stairways. One caution: the copy we downloaded is stamped "Updated 08/2012", cites the 2006 residential code and a minimum U-factor of 0.35. Treat those numbers as the form's age, not today's energy rule, and ask the plans examiner which edition applies; the city lists its examiners at 801-535-7155. For the egress pieces of the schedule, our egress window requirements page explains the sizes.
What skipping it costs
The FAQ is explicit. If the city learns work was done without a permit it issues a Stop Work (red tag) on the address and can charge a double fee. Failing that, a citation may follow, and eventually the city files a Certificate of Non-Compliance on the property, which tells every interested party that work was done without permits and inspections and can hold up the sale until it is resolved. Emergency work is the one exception, with the permit to follow as soon as practical. The city says minor repairs go through a quick-turnaround queue meant to finish in one to three business days (ask whether a window swap qualifies); fees follow the job value, which includes materials and reasonable labor or the contractor's bid.
Who may pull it
An owner may obtain the permit for a structure that is their owner-occupied primary residence, with an Owner/Builder Certification filed with the plan documents. A rental or commercial property needs a contractor to take out the permit and do the work. If you rent out the home, put that in the first sentence of every bid request.
Two meters, two rebates
Most Wasatch Front homes are served by two utilities: Rocky Mountain Power on the electric side and, for gas, ThermWise, which Enbridge Gas (formerly Dominion Energy) runs for its Utah customers. Both pay for new windows. They do not pay the same way, and none of the five top-ranking pages we opened names either program. Rocky Mountain Power's Utah tariff, Schedule 111, was filed with the Public Service Commission on January 23, 2026 under Docket 26-035-T02 and took effect February 27, 2026. Its building-envelope table lists windows at up to $50 per window and low-E storm windows at up to $30. ThermWise's page lists windows at a U-value of 0.22 or lower for $2.50 per square foot, and states that an authorized contractor is not required.
| Program | Window measure? | The shape of it |
|---|---|---|
| Rocky Mountain Power (electric) | Yes: up to $50 per window | Flat per window; storm windows up to $30; incentives capped at 70 % of qualifying cost; heating or cooling conditions in the tariff |
| ThermWise (gas) | Yes: $2.50 per sq ft | U-value 0.22 or lower; authorized contractor not required |
| Federal 25C credit | Ended | Not available for installations after 12/31/2025 |
| Salt Lake City itself | No program found | Neither the permit pages nor the FAQ name a window grant |
Where the two formulas cross
A flat rate against a per-area rate means the better one depends on the glass. At $2.50 per square foot, a 3-by-4-foot window (12 square feet) earns $30 from the gas program, a 3-by-5 earns $37.50, a 4-by-5 (20 square feet) earns $50 and ties the electric rate, and a 5-by-6 earns $75. Small windows favor the flat electric rate; a big picture window favors the area-based gas one. That arithmetic uses the published rates only: both programs apply their own conditions, and the electric amount is an "up to" figure.
Which meter qualifies your home
Read the tariff's own conditions before assuming. Its general terms say a customer with both electric heat and electric cooling is eligible for the electric-heat incentives only, that measures not split by heat versus cooling apply to a customer with either, that electric-heat incentives need a permanently installed electric heat system serving at least 80 % of the conditioned floor area as the primary source, and that cooling incentives need a ducted system serving at least 80 %. By the wording, a gas-heated house with ducted central air looks like the case where both rebates are worth checking, yet the program page decides the final eligibility, and we could not open the Utah window page on the program site, which defaults to another state. The practical step: ask the bidder which program they file, get the NFRC label on the quote, and keep the dated invoice.
Who may do the work in Utah
Utah draws the licensing line by contract value. Under Utah Code 58-55-305, a person doing alteration, repair, remodeling or improvement of a building with a contracted or agreed value of less than $7,000, labor and materials together, is exempt from contractor licensing, and once the total passes $3,000 the person files a one-time affirmation of public liability insurance with the state. A handful of windows can sit under that line. A whole-house project with eight to twelve units usually does not. Above it, the bidder should hand you a license number you can look up with the Division of Professional Licensing, and the insurance certificate that goes with it.
Glass at 4,327 feet
Salt Lake City sits at an average of 4,327 feet above sea level (Wikipedia, city page), so an insulated glass unit built at a lower elevation meets thinner air when it arrives. Cardinal Glass's technical bulletin on the subject states the mechanism plainly: a unit sealed at low altitude and installed at a higher one bows outward, because the sealed pressure at assembly is greater than the pressure at the new elevation, and if the change is large the panes can fracture or the sealant can rupture, ending the seal early. The fix is a capillary or breather tube, or a unit pressure-equalized to its destination. Breather tubes are meant to be sealed once pressure settles. We did not find a Utah rule that dictates the choice, which makes it a question for the quote.
The U-factor line matters twice here: ThermWise sets 0.22 as the bar, and the NFRC label is the paperwork both programs ask for. For how the frame material changes the number, see vinyl vs wood windows. The other high-country guide in this series, our Denver page, treats altitude in passing; the bulletin above is the primary read.
What it costs in Salt Lake City
We have no measured Salt Lake price survey, so the average cost of window replacement in Utah is not something we can quote; the figures below are the national installed bands this site uses on every page, not local quotes. Fit three local items around them: the permit (a fee from the job value), the altitude line on the glass, and the rebate you can file. Since both programs pay the owner after the work, treat each as a later credit rather than a lower bid. For the itemized breakdown behind each band, our installation cost guide lists the lines.
Historic districts: Planning first
For a home in an historic district or a legally recognized historic structure, the city tells owners to contact Salt Lake City Planning before applying for a building permit, and points to Historic Preservation for the maps, standards and design guidelines. The Building Services review-time note adds that exterior repairs, additions and modifications in a Local Historic District must apply for a Certificate of Appropriateness with the Planning Division before the building permit, and the approval is required before the permit issues. The order is therefore: Planning, then the permit, then the work. Ordering windows before the Planning answer is the expensive mistake.
Repair or replace
A failed seal, worn weatherstripping and a dead balance are the repair menu: tens of dollars against thousands for new units. Rotten frames, single-pane glass and drafts you can feel end the debate. Two local twists decide the close calls: the rebates pay for new windows, not repairs, and a replacement carries the permit and the schedule. The when-to-replace guide lists the signals, and drafty windows helps find the leak before you buy.
Choosing a company in Utah
Six paper checks
Utah licenses by contract value and Salt Lake City permits by scope, so the filters are documents, not logos. Ask for the license number when the job passes $7,000, the insurance certificate, the permit and window schedule priced as lines, the whole-unit NFRC values, the altitude answer for the glass, and references from your part of the valley.
Big-box installs and out-of-state crews
Home improvement chains and national brands sell the windows and send a subcontracted local crew. Run that crew through the same six checks, and ask who pulls the permit: an owner may do it only for an owner-occupied primary residence, and a rented home needs a contractor.
West Jordan, Sandy, Ogden, Provo
The utilities and the state licensing rule travel along the Wasatch Front; the permit answer does not. For West Jordan, Sandy, Ogden and Provo we found no official page that names windows, only third-party summaries, and those are no match for the city that sits between them and says permits are required. Rocky Mountain Power and ThermWise serve the whole corridor, so the money map above applies; the paperwork answer is a call to each city's building office, put in writing, and written into the quote.
What we read, and how
This page is built on primary reads, all dated 22 October 2026: Salt Lake City's Building Services FAQ, where windows are named, and its window schedule form; Rocky Mountain Power's Utah Schedule 111; ThermWise's weatherization rebate page; Utah Code 58-55-305; and Cardinal's bulletin on insulated glass at altitude. Where an official page was not found, as for the four suburbs, the page says so rather than guessing.
The limits of this read
City pages and tariffs change, the Utah window page of the electric program would not open for us, and the rebate crossover is arithmetic on published rates, not a promise of what either utility will pay on your invoice. The written bid and the program's own confirmation are the versions that count. For how long the new units should serve, the window lifespan page sizes it up.
The rest of the wave: Denver at a similar altitude, Seattle with its four utilities, Fort Worth where the permit is also required, Dallas where it is waived, and Charlotte with its compass rebate.
The questions Salt Lake City actually asks
How much does window replacement cost in Salt Lake City?
Per opening, our installation cost guide puts a standard vinyl double-hung insert at $400 to $900 installed. Those bands are national, not a Salt Lake survey: we have no measured local price data, so use them as the frame and let itemized quotes set the position. Three Salt Lake lines move the arithmetic. The city permit belongs in the quote as its own line, priced from the job value. Glass made or equalized for 4,327 feet of elevation can add a line a sea-level quote omits. And the two utility rebates, worth tens of dollars per window, reach you only if the quote lists NFRC whole-unit values. For the labor behind the bands, our installation cost guide carries the hours; the binding number for your house is the itemized written quote.
Do I need a permit to replace windows in Salt Lake City?
Yes. The city's Building Services FAQ answers the question in its first words: permits are required to replace exterior doors or windows, and a window schedule listing each window's size, type and room goes in with the application. That is stricter than the like-for-like exemption in Seattle, Charlotte or Dallas. The city routes minor repairs through a quick-turnaround queue of one to three business days; ask the permit office whether a window swap qualifies. Skipping it risks a stop-work order, double fees, and a Certificate of Non-Compliance recorded against the property, which can hold up a sale.
Is there a Salt Lake City or Utah free window replacement program?
We found no city or state handout. The closest thing is weatherization: Rocky Mountain Power's tariff names Weatherization Assistance Program contractors as eligible for window incentives on WAP-approved projects, but that is an income-qualified channel, not a free-windows entitlement. The money any owner can claim is the pair of utility rebates covered above: Rocky Mountain Power on the electric side, ThermWise on the gas side. The federal 25C credit ended with 2025 installations.
Is there a Utah window rebate in 2026?
Two, and they do not use the same formula. Rocky Mountain Power's Utah tariff (Schedule 111, effective February 27, 2026) lists windows at up to $50 per window and low-E storm windows at up to $30. ThermWise, the gas program run for Enbridge, pays $2.50 per square foot for windows with a U-value of 0.22 or lower, and does not require an authorized contractor. A home with both gas heat and electric service can check each; confirm the current terms on the program pages before you order, because the rebates change.
Is there a Utah window tax credit?
The federal 25C window credit ended with 2025 installations, so a window installed now earns no federal credit. We did not find a Utah state window credit in any program page or statute we read; the money that exists for a Utah owner is the pair of utility rebates above. Tax rules are the one place to ask a preparer rather than rely on a guide, and a rebate check can change how an expense is treated.
Who can legally install windows in Utah?
Utah's Construction Trades Licensing Act exempts a job with a contracted value under $7,000, labor and materials together, from needing a contractor license, and asks the unlicensed worker for proof of insurance once the job passes $3,000. A whole-house window project often clears $7,000, so ask for the DOPL license number and look it up. For a rental property, the city requires a contractor to pull the permit and do the work; an owner-occupant can pull it for their primary residence with an Owner/Builder Certification.
Who are the best window replacement companies in Salt Lake City?
We do not rank companies; this guide is independent. What filters bidders: a Utah license number that checks out when the job is above the thresholds, insurance you can verify, the permit and the window schedule priced in writing, whole-unit NFRC values on the quote, a line stating how the glass is equalized for altitude, and references from your valley. The bidder whose documents survive all six has earned the price.
Should I repair or replace my windows in Salt Lake City?
Run the test before collecting bids. A failed seal that fogs the glass, tired weatherstripping or a dead balance is repair-menu work. Rotten frames, single-pane glass and drafts you can feel on a winter night end the debate in favor of new units. One local branch: both rebates pay for new windows, so a repair earns none, and a replacement means the permit and the window schedule.
Do I need a permit if my home is in a historic district?
You need two approvals, in order. Salt Lake City's FAQ tells owners of homes in an historic district, or a legally recognized historic structure, to contact city Planning before applying for the building permit, and its review-time note says exterior repairs and modifications in a Local Historic District apply for a Certificate of Appropriateness first. That approval is required before the building permit is issued. Build the extra weeks in before the units are ordered.
Does altitude matter for windows in Salt Lake City?
It can. Cardinal's technical bulletin on insulating glass explains that a unit sealed at low altitude and installed much higher bows outward because the sealed pressure is higher than the air outside, and that in severe cases the panes can fracture or the seal can rupture. The remedy is capillary or breather tubes, or units pressure-equalized for the destination. Salt Lake City sits near 4,327 feet. Ask the supplier, in writing, how your units are equalized, and whether any breather tubes are closed after install.
What about West Jordan, Sandy, Ogden and Provo?
The utilities and the state licensing rule are the same across the Wasatch Front, but each city runs its own building office, and for these four we found no official page that names windows. Third-party permit summaries say same-size swaps are exempt in several Utah cities; treat that as a rumor, because Salt Lake City, a few miles away, says the opposite. Call the building office, get the answer in writing, and make the bidder put it in the quote.
Can I replace my own windows in Salt Lake City?
Legally, for your own primary residence, yes: the city lets an owner pull the permit with an Owner/Builder Certification, and the state licensing exemption covers an owner working on their own property. Practically, a botched install voids unit warranties and fails inspection, and a rebate claim needs the units' NFRC labels, so keep them. The gas program does not require an authorized contractor, so a careful owner can claim it; the electric program's rules for self-installed windows are on its program page.
How long does window replacement take in Salt Lake City?
Measure to install typically runs two to six weeks, mostly unit fabrication; the on-site work is usually a day or two for a whole house. Add the Salt Lake City steps: the permit application with the window schedule before work (one to three business days in the quick queue) and the inspection after. Historic-district homes add the Planning review first.
