Window Replacementin Pomona, CA
Window replacement in Pomona falls under EPA's lead-safe rules in any home built before 1978, and the state's permit-exempt list has no window item, so confirm the permit with Building and Safety. In a historic district, a window change is reviewed as an alteration. Order the units only after the City answers.

Windows show the age of a Pomona house faster than almost anything else. About 11.8 percent of the city's homes date from 1939 or earlier and about 39.8 percent from before 1960, according to the Census Bureau's 2024 estimates, so the opening you are measuring may belong to a house near Lincoln Park or to a tract home from the years after Interstate 10 reached the city in 1954, when Pomona grew 89.7 percent in a decade to 67,157 people by 1960.
This page covers what is particular to Pomona: heat, lead paint, the permit question, historic districts and the small fire-zone pockets. MDG Builders (CSLB #1040337) writes the scope, handles the permit and supervises, and a licensed glazing or window installation subcontractor sets the units. Frame materials and glass types are on our windows page, and the Pomona overview lists the other trades we manage here.
What applies to windows in Pomona: state rules, lead and historic review
Where windows permits come from in Pomona: City of Pomona Development Services Department, Building and Safety Division.
- The state R105.2 permit-exempt list has no window or door item, and EPA's rule says window replacement is always covered by the lead-safe work rules in pre-1978 housing regardless of square footage. Pomona's waste rule lists windows and doors among salvageable materials for the 50 percent diversion requirement.
- On a Pomona historic landmark or in a historic district, any exterior change to character-defining features counts as an alteration reviewed by the Planning Division through a Minor Certificate of Appropriateness. The code's examples of Minor Work list no window item, so a window replacement in a district should be confirmed with Planning.
- CSLB defines the C-17 Glazing classification as selecting, cutting, assembling and installing glass, mirrored glass and glass substitute materials, and fabricating and glazing frames, panels, sashes and doors.

Which replacement windows suit Pomona's summers?
NOAA's 1991 to 2020 normals for the Pomona/Fairplex station show average highs from 67.9 degrees in January to 92.4 in August, with 70.5 days a year at or above 90 and 10.7 at or above 100. The same station records only 2.7 freezing nights a year and 14.47 inches of rain, almost all of it from December through March. That pattern points to a cooling problem more than a heating one, so glass that holds back afternoon sun is the first question.
Angi's Los Angeles data prices double-pane at $500 to $2,000 per window and low-emissivity coatings at $300 to $1,100 per window, and we found nothing more specific for Pomona. We print no U-factor or solar heat gain numbers, since published handouts disagree and we did not read the adopted energy code table for Pomona's climate zone. Ask for the label from the National Fenestration Rating Council on every unit and keep it on until the inspector has looked.
Low-E glass in a historic district is a separate question for Planning, because a reviewer may have views on coatings. We did not find a Pomona rule either way.

Lead-safe rules for replacing windows in a Pomona house built before 1978
Pulling an old frame disturbs every coat of paint on it. The U.S. Environmental Protection Agency's Renovation, Repair and Painting rule covers paid work that disturbs paint in housing built before 1978, applies to general contractors and sole proprietors alike, and requires certified firms and lead-safe work practices. Its minor-repair exception stops at 6 square feet per room inside or 20 square feet outside, and window replacement is always covered.
That matters here because about 65.7 percent of Pomona's housing units were built before 1980. We could not find a count for before 1978 alone, so assume the rule applies unless the build year says otherwise.
Ask the window firm for its EPA certification next to its contractor license, and ask how floors will be covered, how debris leaves the house and who cleans the sill and jamb at the end of each day. Our license check guide shows how to verify the state license.
- Can you see the firm's EPA lead-safe certification, not just a claim of it?
- How will each room be sealed off and cleaned at the end of the day?
- Where will painted frames and debris be taken, and who keeps the receipts?

Do you need a permit to replace windows in Pomona, California?
Plan on one until Building and Safety says otherwise. The state's list of work exempt from a building permit, as the City of Albany excerpts it, names sheds, fences, small retaining walls, driveways and finish work such as painting and carpeting, but no window or door item. Pomona's Article II, adopted under Municipal Code section 74-31, lists no change to that list.
We could not open the City's handouts, which block automated readers, so we cannot tell you whether a same-size swap goes over the counter or needs drawings. A larger opening, a new opening or a window turned into a door is more likely to need plans because it cuts the wall framing. Ask the Building and Safety Division and get the answer in writing, since the unlicensed minor-work limit of $1,000 does not apply when a permit is needed.
The state classification for glass work, C-17 Glazing, is described on the CSLB site. MDG manages the job and uses licensed subcontractors for the install, and you can ask for each one's license number and certificate of insurance.
Keep the permit card and the final inspection sign-off with your house records, since a later buyer or insurer may ask for them.

Replacement windows in Lincoln Park, Wilton Heights and Pomona's other historic districts
Pomona's zoning code names six historic districts, each carrying an -H overlay: Hacienda Park, Lincoln Park, Wilton Heights, Edison, Civic Center and Landmark Quarter. On a landmark or in a district, any exterior change to character-defining features counts as an alteration reviewed by the Planning Division through a Minor Certificate of Appropriateness, and the permit waits for it.
The zoning code lists examples of minor work, among them like-for-like re-roofs, chimney repairs, solar panels and some fences, but no window item. A replacement in a district should therefore be confirmed with Planning before you order. Lincoln Park has 821 structures, mostly built from the 1890s to the 1940s, and windows are among the features most visible from the street.
Send the Planning Division your address and photos of the windows from the street. A proposal that repairs a failing sash, or matches the original operation, pane count and profile, is easier to approve than one that changes the look.

Fire zone glass: do replacement windows in Pomona need tempered panes?
For most Pomona addresses the question never comes up. Our screening of CAL FIRE's older Local Responsibility Area layer against the city outline found Very High polygons over about 1 percent of the city, mostly around Elephant Hill next to the Phillips Mansion in Spadra, a handful of points on the west edge near the Cal Poly Pomona campus and one in the north. It is not the 2025 recommended map and not a parcel answer.
Municipal Code section 74-32, in the Article II text, requires Chapter 7A of the California Building Code for new construction or building expansion in a Very High zone. It does not say what a window-only job must meet. For comparison, Los Angeles's fire zone checklist asks for multilayer glazing with at least one tempered pane on altered exterior windows, but that is the other city's rule.
Check your parcel on the City's fire hazard page and ask Building and Safety in writing. Tempered panes are cut to size and cannot be altered afterward, and Angi's Los Angeles data adds $200 to $700 per window for them, so settle the answer before the order.

What do replacement windows cost for a Pomona house, and where do the old ones go?
We found no Pomona price study with a stated method, so these are Los Angeles area numbers. Our window cost table works from vinyl units at about $550 to $1,200 each installed and $14,000 to $28,000 for 10 to 15 windows. Remodeling magazine's 2025 Cost vs. Value report for Los Angeles lists vinyl replacement at $23,783 with $19,799 recouped at resale, 83.2 percent, and wood at 81.9 percent.
The federal 25C window credit does not apply to property placed in service after December 31, 2025, according to the IRS, so be wary of any salesperson who still quotes it.
Pomona's construction waste rule, sections 62-871 to 62-874 of the Municipal Code, lists windows and doors as salvageable materials and requires at least 50 percent of a permitted project's waste to be reused or recycled. Ask where your old units will go and who keeps the hauler receipts.

What windows costs around Pomona
The figures above are regional ranges from our windows page, not a Pomona quote, and tempered glass, historic matching and lead-safe containment are the usual reasons a bid moves up. Each shows as its own line in a written proposal. The median owner-occupied home in Pomona is valued at $636,700, but the Cost vs. Value report measures Los Angeles, so read it as a benchmark. Pomona's neighbors Claremont, La Verne and Walnut are separate cities with their own building departments. For comparison, read the Glendale, Pasadena and Los Angeles pages. The same house may need a bathroom remodel in Pomona or a room addition in Pomona, and our subcontractor guide explains who does what on a managed job.

Pomona window replacement questions, answered
Do you need a permit to replace windows in Pomona, California?
Plan on one. The state's permit-exempt list has no window item, and Pomona's code lists no local change to it. We could not read the City's handouts, so we cannot say whether a same-size swap goes over the counter. Ask Building and Safety, get the answer in writing, and note that a new or enlarged opening is more likely to need drawings.
How much is a permit to replace windows in Pomona, California?
We could not verify an amount, so we print none. Pomona's fees are set by council resolution that we could not open, and the code text lists no dollar figures. Sites that quote a number rarely say where it came from. Ask Building and Safety for a fee estimate for your scope, and confirm what the inspection covers.
Do I need special fire-resistant windows if I live in a Pomona fire hazard zone?
Possibly, but only a small share of Pomona sits in a Very High zone, by our screening about 1 percent. Section 74-32 requires Chapter 7A for new construction or expansion there, and it does not say what a window-only job must meet. Check your parcel on the City's fire page and ask Building and Safety before ordering glass.
How much does it cost to replace windows in California for a Pomona house?
About $550 to $1,200 per vinyl window installed, and $14,000 to $28,000 for a house with 10 to 15 windows, using Los Angeles area sources because we found no Pomona study. Wood, fiberglass, tempered glass and historic matching cost more. Your written proposal prices each opening, and that proposal is the real number.
Do I need lead-safe work to replace windows in a Pomona house built before 1978?
Yes. EPA's rule covers paid work that disturbs paint in housing built before 1978, and window replacement is always covered, whatever the square footage. About 65.7 percent of Pomona's homes predate 1980, so ask any window firm for its EPA certification and how it will contain dust, protect floors and remove debris.
Is replacing windows worth it in Pomona, and does it add home value?
It recovers most of its cost at resale in Los Angeles, not all of it. The 2025 Cost vs. Value report puts vinyl replacement at 83.2 percent recouped and wood at 81.9 percent. We found no Pomona figure. With 70.5 days a year at or above 90 degrees, comfort is a real reason, and in a historic district matching the original matters too.
Does a Pomona historic district house need approval to replace windows?
Probably. On a landmark or in one of the six historic districts, exterior changes to character-defining features are alterations reviewed through a Minor Certificate of Appropriateness. The code's minor-work examples list no window item, so confirm with the Planning Division before you order, and send photos of the street-facing windows with your address.
Are double pane windows required in California for a window replacement in Pomona?
Yes for most homes. Los Angeles's permit bulletin cites Title 24, Part 6, Section 150.2(b)1B for labeled dual glazing on replacement windows in residential buildings of three stories or less, and Pomona adopts the 2025 Energy Code. We print no U-factor numbers. Ask for the NFRC label on each unit and keep it for the inspector.
How long does it take for new windows to be installed in Pomona?
Installation takes about one to three days for a house of 10 to 15 windows, but the factory wait comes first, usually 4 to 8 weeks by our planning estimate, longer for custom sizes or special glass. Permit approval and manufacturing can often run at the same time. Ask for the ship date in writing before you sign.
Is there a tax credit for replacement windows in Pomona?
Not a federal one now. The IRS says the 25C credit does not apply to property placed in service after December 31, 2025. We did not confirm a Pomona utility rebate for windows, so ask your electric provider about current programs, and be cautious about any salesperson who still advertises the federal credit.
Tell us the street and how many windows
Send the address, the number of windows, the year the house was built and whether it sits in a historic district, and we will check lead, permit and fire pocket questions before we call.
