Window Replacementin Pasadena, CA
Window replacement in Pasadena usually starts with a City permit and, in a landmark district such as Bungalow Heaven, staff review of any window visible from the street. Plan to match the original window's design, check the fire hazard zone map before ordering glass, and use a lead-safe certified firm in any house built before 1978.
Pasadena window jobs split by address more than by window size. The City's own design guidelines trace the town to the Indiana Colony's January 1874 survey, a name chosen in 1875 and incorporation in 1886, and say Craftsman design flourished here from about 1905 to the 1920s, which is why so many frames are wood sashes with a horizontal emphasis. The adopted 2021-2029 Housing Element says 85 percent of the housing stock was built before 1990, so most new units go into openings older than the energy code they must meet. A house in Madison Heights, Lamanda Park or Orange Heights may sit inside one of the six areas the City has designated as historic districts, near the Arroyo Seco fire zone, or both.
MDG Builders (CSLB #1040337) is a general contractor in Tarzana. We measure, write the scope, file the permit and keep the schedule, and a licensed glazing or window installation subcontractor sets the units. Our window guide covers frame materials and glass; this page covers what is particular to Pasadena, and the Pasadena overview lists the other trades we manage here.

Can you replace windows in Bungalow Heaven or another Pasadena historic district?
In Bungalow Heaven, the conservation plan adopted by the City Council on June 16, 2025 sorts work by whether a house is contributing, meaning it kept its historic character. For a contributing house, replacing or altering windows and doors, or changing their openings, goes to City staff review when it is visible from the public right-of-way. Window grilles, screens, awnings and all interior alterations are listed as not subject to review, and so is anything you cannot see from the street. For a non-contributing house, only changes to the openings are reviewed.
The City's Master List of Resources decides which category your house falls in, so look it up before you order anything. The City's historic preservation page says a Certificate of Appropriateness has no fee but can delay a building permit by about 2 months, and that paint colors are exempt. Garfield Heights and Banbury Oaks have their own conservation plans and the City counts six districts in all, so do not assume Bungalow Heaven's lists apply to them. Questions go to dhpquestions@cityofpasadena.net.
Sending the address to Design and Historic Preservation staff before you collect quotes costs nothing and can save a re-order.
What do Pasadena's historic design guidelines say about replacement windows?
The City's Design Guidelines for Historic Districts, dated April 2002, lean toward repair. They say to repair a historic window rather than replace it, and they treat a window as worth preserving, with selective replacement of parts, when more than half of its components can be repaired. A rotted sill may need replacing, in their words, without meaning the whole window has failed.
When replacement cannot be avoided, guideline 7.10 asks for the same operation, the same number and position of panes, a matching profile and opening depth, and the original casing kept where feasible. Wood is preferred. A substitute material can be considered if its dimension, profile and finish match and it has shown durability in this climate. The same guideline discourages low-emissivity glass in new or replacement windows, which sits awkwardly next to the energy code, so ask staff before specifying a coating.
Guideline 7.11 calls large sheets of glass inappropriate on historic houses and suggests putting them on secondary walls and dividing them into smaller windows. The text is 24 years old, and under the heading for doors it says the City may apply the State Historical Building Code where requirements conflict. Ask staff whether they would do the same for your windows.
Do you need a permit for window replacement in Pasadena?
Plan on one. The City's building permit application lists Roof/Stucco/Siding/Window as a permit type, and its list of work exempt from a building permit names sheds, non-masonry fences, small retaining walls, decks, driveways and finish work such as painting and carpeting, but not windows. We found no Pasadena handout for window change-outs and no published fee, so we quote neither. The sheet also warns that a zoning permit may be required for exempt work.
A contractor pulling the permit presents a valid contractor license and a current Pasadena business license, and permits last 180 days from issuance. The Permit Center says simple projects can be reviewed over the counter in as little as 5 to 10 minutes and complex plans take two to four weeks. Which side a same-size swap lands on is a question for the counter at (626) 744-4200, and a bigger window or a window turned into a door is more likely to need drawings.
Pasadena sits in Energy Climate Zone 9 on the City's design parameters sheet. We print no U-factor or solar heat gain numbers, because city handouts elsewhere disagree and we did not read the adopted text. Keep the NFRC label on every unit until the inspector has seen it.
Do replacement windows in a Pasadena fire hazard zone need tempered glass?
The Fire Department says its zones lie generally in the Arroyo Seco, west and north of the 210 freeway, and in upper Hastings Ranch. CAL FIRE's map dated March 24, 2025 would raise the Very High count from 3,911 to 4,610 properties, but we could not confirm the Council adopted it. Look up your parcel on the Fire Department's zone page and ask which map the Permit Center applies.
Nothing we read settles whether a window-only job needs fire-rated glazing. CAL FIRE's statewide FAQ, which the Fire Department posts, says Chapter 7A applies to new buildings in High and Very High zones and that local ordinances may require ignition-resistant construction for remodels. For comparison, Los Angeles's fire-zone checklist asks for multilayered glazing with at least one tempered pane on altered exterior windows. Until the Permit Center answers in writing, we price that build for a zone address, since tempered panes are made to size and cannot be cut afterward.
Eaton Fire rebuilds follow a separate track. The City says 185 structures burned in Pasadena, mostly in Upper Hastings Ranch, Victory-Rose, Dundee Heights and NATHA, that Council reduced or waived plan check and permit fees for eligible rebuilds, and that the Permit Center lists optional 2022 codes for them. Windows for a rebuild are ordered against the approved plans, not from a catalog.
What lead-safe rules apply when you replace windows in a Pasadena house built before 1978?
The Housing Element warns that homes from before the 1970s may carry lead-based paint and asbestos, and it describes a Public Health Department program whose specialists advise on lead-safe painting and remodeling. Pulling out an old frame disturbs every coat of paint on it, so window work is where that warning turns practical.
EPA's Renovation, Repair and Painting rule covers paid work that disturbs paint in homes built before 1978 and requires the firm, including sole proprietors, to be certified. The federal minor-repair line is 6 square feet of painted surface per room indoors or 20 square feet outdoors, with no window replacement or demolition, and jobs in the same room within 30 days count together. So a window swap does not qualify for the small-job exception. EPA's page does not list California among the states running their own program.
Ask the window firm for its EPA certification alongside its contractor license, and ask how floors will be covered and how debris leaves the house. Our Pasadena painting page covers the same rule from the paint side.
What do replacement windows cost for a Pasadena house, and do they pay back?
We found no Pasadena price study with a stated method, so these are Los Angeles numbers. Our window cost table works from vinyl units at about $550 to $1,200 each installed and $14,000 to $28,000 for a house with 10 to 15 windows, ranges we rate medium in confidence because three sources overlap.
Remodeling magazine's 2025 Cost vs. Value report for Los Angeles lists vinyl window replacement at a $23,783 job cost and $19,799 in resale value, 83.2 percent recouped, with wood at 81.9 percent. The public page does not say how many windows that job covers. Census Reporter's ACS 2024 page puts Pasadena's median owner-occupied home value at $1,209,600, but the report describes Los Angeles, so read it as a benchmark.
Summer highs of 89.1 degrees in July and 91.3 in August, from the NOAA normals Wikipedia cites, are why owners ask about glass coatings, and in a landmark district that question goes to staff first. The IRS says the federal 25C window credit does not apply to property placed in service after December 31, 2025, and we found no confirmed Pasadena Water and Power window rebate, so check PWPweb.com/SaveEnergy before counting on one.

What windows costs around Pasadena
Figures above are the Los Angeles based ranges from our windows page, not a Pasadena quote. Staff review in a landmark district, tempered glass in a fire zone and lead-safe containment are the usual reasons a bid moves up, and each shows as its own line in a written proposal. Anyone you hire can be checked first; our license check guide shows how, and the subcontractor guide explains who does what on a managed job. The same house often needs other work, so see roofing in Pasadena, fence installation in Pasadena, window replacement in Los Angeles and painting in Glendale; Glendale runs its own counter, listed on the Glendale overview.

Pasadena window replacement questions, answered
Do I need a permit to replace windows in Pasadena?
Plan on a permit. The City's application lists Roof/Stucco/Siding/Window as a permit type, and its exempt-work sheet does not name windows. We found no Pasadena handout or fee for a like-for-like swap, so confirm with the Permit Center at (626) 744-4200 whether your job goes over the counter. Your written proposal names the permit and who pulls it.
Do I need special fire-resistant windows if I live in a Pasadena hillside fire zone?
Possibly, and it depends on the work and the map. CAL FIRE's FAQ says Chapter 7A covers new buildings in High and Very High zones and that local ordinances may require ignition-resistant construction for remodels. Ask the Permit Center in writing before ordering, because tempered or multilayer panes are made to size and cannot be cut afterward.
Can I replace my windows in Bungalow Heaven without approval?
Only if the windows are not visible from the street, or the house is non-contributing and the openings stay the same. For a contributing house, the district plan sends replacement of street-visible windows to City staff review, while interior work, grilles, screens and awnings are not reviewed. Check the Master List of Resources first.
Do new windows increase home value in Pasadena?
They recover most of their cost at resale in Los Angeles, not all of it. The 2025 Cost vs. Value report puts vinyl window replacement at 83.2 percent recouped and wood at 81.9 percent, but it measures Los Angeles, and we found no Pasadena figure. In a landmark district, matching the original design can matter as much as the glass.
How do I know if my windows need to be replaced?
Peeling paint and stiff sashes alone do not mean a window is beyond saving. Pasadena's historic guidelines say a window merits preservation when more than half its components can be repaired, and that a rotted sill may need replacing without a whole new window. Replacement makes more sense when frames are failing broadly or glass cannot be repaired.
Is there a tax credit or rebate for replacement windows in Pasadena?
Not a federal one anymore. The IRS says the 25C credit is not allowed for property placed in service after December 31, 2025. We found no confirmed Pasadena Water and Power window rebate either, so check PWPweb.com/SaveEnergy for current programs, and be wary of any salesperson who quotes a credit the IRS page says has ended.
Are replacement windows required to be Title 24 compliant in Pasadena?
Yes, new windows must meet the California Energy Code, and the City places Pasadena in Energy Climate Zone 9. We print no U-factor or SHGC numbers because published city handouts disagree and we did not read the adopted text. Ask for the NFRC label on each unit and keep it on until the inspector has seen it.
Can you match existing windows for a remodel or addition in Pasadena?
Yes, and in a historic district the City expects it. Guideline 7.10 asks for the same operation, pane count and position, a matching profile and the original opening depth, with wood preferred. A custom match is built to order, so we send the manufacturer's drawing to staff before anything is ordered.
What is the lead time for a window and door order in Pasadena?
It depends on the manufacturer, the glass and whether the unit is a custom match, and we did not verify a Pasadena figure. Ask for the ship date in writing before you sign, because tempered, laminated and historic-profile units are built to order. Permit approval and manufacturing can usually run at the same time.
How much does window replacement cost in Pasadena?
We found no Pasadena study with a stated method, so use Los Angeles figures: roughly $550 to $1,200 per vinyl window installed, and $14,000 to $28,000 for 10 to 15 windows. Wood, fiberglass, fire-zone glass and landmark-district matching cost more. Your written proposal prices each opening, and that proposal, not an average, is the real number.
