Window Replacementin Inglewood, CA
Window replacement in Inglewood needs a Residential Alteration permit even for same-size, same-type windows, though the City asks for no plans. Its handout caps replacement windows at a U-factor of 0.30 and an SHGC of 0.23, with an exception for small areas. Near LAX, ask about the sound insulation program before you buy.
The City's Safety Element says multiple LAX approaches pass over the greater part of Inglewood and calls aircraft noise and air pollution critical issues. Add the age of the housing, with 78.1 percent of units built before 1980 in the 2020 to 2024 American Community Survey, and a window here has two jobs: keep out heat and sound, and survive a house that may be seventy years old.
This page covers the sound insulation program, what the City's window handout requires, the energy numbers it sets, egress and glass rules, and the retrofit-or-full-frame choice for a 1940s or 1950s house. Prices and the phase timeline are on our window replacement page, and the Inglewood overview lists the other trades we manage here.
What Inglewood's window handout and sound program say
Where windows permits come from in Inglewood: City of Inglewood Development Services Department, Building Safety Division.
- The City's Residential Window Replacement handout says replacing windows with the same size and type needs a Residential Alteration permit but no plans. The windows or sliding doors must still meet the 2022 California codes for light and ventilation (glazing at least 8 percent of floor area, openable at least 4 percent), emergency egress from sleeping rooms, tempered glazing where required, and, if a door is replaced, at least one exterior door 36 inches wide (32 inches clear).
- Same handout: replacement windows must have a maximum U-factor of 0.30 and SHGC of 0.23 (up to 75 square feet of glazing replaced may be 0.40 and 0.35). Egress openings need at least 5.7 square feet of net clear area (5.0 at grade or below), at least 20 inches clear width and 24 inches clear height, with the sill no higher than 44 inches. Relocating, deleting or adding windows requires a scaled floor plan with window sizes, types and header sizes.
- The City's presale report must state the LAX impact levels and the attenuating effect of any sound insulation program at the property, and the RSI Department funds sound modification for eligible owners inside the 2020 Noise Exposure Contour Map, so window and door work near the airport can be tied to an existing sound insulation record.
Will new windows help with LAX noise, and what is Inglewood's sound insulation program?
The City's Residential Sound Insulation Department administers Federal Aviation Administration and Los Angeles World Airports grants that pay for sound modification for eligible owners inside the 2020 Noise Exposure Contour Map. The department says it served 2,075 property units in 2015 and that guidelines effective January 2016 identified about 3,700 more. Contact is soundinfo@cityofinglewood.org or 310-412-5289.
Ask whether your address is eligible or already treated before you order anything, because a grant-funded installation is a different job from a retail purchase, and we have not confirmed how replacing program windows affects a property's record. If you buy on your own, ask the manufacturer for tested sound ratings in writing and treat a vague promise of quiet as unproven. Glass is one path for noise, and walls, doors and attic openings carry sound too.
The department's page is the place to confirm eligibility, scope and waiting time, and we found no published figure for any of them, so we do not guess. If your address falls outside the contour, the program does not apply and the window choice is yours alone.
Does Inglewood's presale report show window work and sound insulation?
Under Article 8 of Chapter 11 in the Municipal Code, a seller must pull the City's presale report, and it carries two entries a window buyer cares about: the LAX impact levels at the property and the attenuating effect of any sound insulation program there. It also lists permit numbers and dates and any code violations an inspector observed, and it stays valid for six months.
That makes the window file part of the sale. Keep the permit final, each window's rating label and any sound insulation paperwork together, so a buyer's agent can match the report to the house. If windows were changed without a permit, the list of permits on file is where the gap shows.
If you are selling, order the report early. Because it covers the legal number of units and whether the lot is in the fault zone as well, a clean window record is one item among several that a buyer's agent will check.
Do you need a permit to replace windows in Inglewood? What the City's handout says
Yes. The City's Residential Window Replacement handout says replacing windows with the same size and type takes a Residential Alteration permit but no plans. Relocating, deleting or adding a window raises the bar to a scaled floor plan showing window sizes, types and header sizes. Inspections are requested through the City's OpenGov portal once the permit exists.
The handout holds windows to the 2022 California codes, although the Municipal Code on eCode360 still lists older editions, so confirm with the Building Safety Division at (310) 412-5294 which edition your permit will cite. Starting before the permit issues is charged double the fee. Work described as painting or finish carpentry is exempt, but a new frame in a wall is not finish work.
When we price a window job we list every opening with its size, type and glazing, which is the same information the permit card and inspector will want. We measure each rough opening on the site visit, because the handout's light and egress tests depend on those measurements, and photos of each elevation help.
What U-factor and SHGC does Inglewood want in replacement windows?
The City's handout sets a maximum U-factor of 0.30 and a solar heat gain coefficient (SHGC) of 0.23 for replacement windows, with an allowance of 0.40 and 0.35 for up to 75 square feet of replaced glazing. U-factor measures how fast heat passes through the window, and SHGC measures how much sun heat gets in, so lower is better for both. An NFRC label on each window states its certified numbers, and Title 24, Part 6 is the energy code behind them.
Inglewood is Climate Zone 8 according to the City's roof handout, and NOAA's 1991 to 2020 normals for the LAX station show 4.8 days a year at or above 90 F and no freezing days, with August highs near 76.7 F. That makes a low SHGC on west and south walls a sensible priority, and we do not print energy savings numbers because we found no sourced one for Inglewood. Our bathroom page for Inglewood covers the exhaust fan side of the same code.
Egress, light and safety glass: which replacement windows must change size?
The handout requires glazing of at least 8 percent of the floor area and openable area of at least 4 percent, emergency egress from sleeping rooms, tempered glass where required and, if a door is replaced, at least one exterior door 36 inches wide with 32 inches clear. A same-size swap can still fail these tests if the old window never met them, and an inspector can ask.
For a bedroom egress opening, the handout sets a minimum net clear area of 5.7 square feet, or 5.0 at or below grade, at least 20 inches of clear width, 24 inches of clear height and a sill no higher than 44 inches. A double-hung window that looks large can have a net clear area well under that, since the sash blocks half of it. Casement and slider styles tend to open more, so we measure before choosing the style. When we are unsure whether an existing window met those tests, we say so in the proposal and ask Building Safety before ordering, because a rejected size is a costly reorder.
Replacing windows in a 1940s or 1950s Inglewood house: retrofit or full frame?
The 1940s account for 15.5 percent of Inglewood's units and the 1950s for 18.3 percent, so many windows here sit in stucco walls from tract-era houses such as Inglewood Knolls. A retrofit window slides into the old frame and keeps the trim and stucco intact, while a full-frame replacement removes the frame so the flashing and the framing around the opening can be seen. Termite damage is rated Very Heavy in the City's code table, so an opened sill sometimes needs wood repair.
The Housing Element flags lead-based paint on pre-1978 homes, and EPA's lead-safe rule covers paid work that disturbs paint in them, so ask for the certification. The only historic zoning district we found in the Municipal Code is the H-C Historic Core in the downtown, aimed at retail, restaurants, offices and housing, and the zoning map also lists an Art Deco overlay. Ask Planning at (310) 412-5230 whether your address is in either one.
How long does window installation take, and who may install windows in Inglewood?
Ask for the lead time on windows and doors in writing, because made-to-order units can take longer to arrive than they take to install. Section 5-41 of the Municipal Code and the City's Inspections page allow construction work from 7:00 a.m. to 8:00 p.m. every day, so install day can be scheduled around the household. MDG Builders, CSLB #1040337, manages the order, permit and schedule, and we name the licensed installing subcontractor in the proposal.
CSLB's C-17 glazing classification covers glass and glazing work, but its wording does not mention windows by name, so which license class may legally replace a window is something to ask any bidder and verify on the CSLB site, as our post on checking a contractor license shows. California's home improvement contract law, Business and Professions Code section 7159, requires a signed contract over $500 with the license number, a down payment of no more than $1,000 or 10 percent, whichever is less, and progress payments tied to work done.

What windows costs around Inglewood
Our window replacement page shows vinyl replacement windows at about $550 to $1,200 each installed and a whole-house job of 10 to 15 windows at about $14,000 to $28,000, with wood and fiberglass costing more. The ranges come from three sources that overlap near $19,000 to $24,000 for a typical house: Angi's Los Angeles page, updated July 2026, with an average of $19,356; Remodeling magazine's 2025 Cost vs. Value report for Los Angeles, which lists vinyl replacement at $23,783 and 83.2 percent recouped at resale; and ConsumerAffairs. We found no Inglewood price study and no City permit fee, so neither is printed. The federal 25C tax credit does not cover property placed in service after December 31, 2025, though many web pages still advertise it. For other cities, see the pages for Los Angeles, Compton and Long Beach. New windows often come with a room addition or an ADU.
| What it covers | Typical range |
|---|---|
| Vinyl window, installed, each | $550 to $1,150 |
| Wood or fiberglass window, installed, each | $950 to $2,400 |
| Whole house, 10 to 15 windows | $14,000 to $28,000 |
| Glass options, per window | Double-pane $500 to $2,000. low-E $300 to $1,100. tempered $200 to $700. |
| Remodeling Cost vs. Value 2025, Los Angeles | Vinyl $23,783. wood $27,913. |
| New or enlarged egress opening | $3,200 to $6,500 |
Inglewood window permit, LAX noise and egress questions
Do I need a permit to replace windows in Inglewood?
Yes. The City's handout says replacing windows with the same size and type needs a Residential Alteration permit but no plans, and changing, adding or removing openings needs a scaled floor plan with header sizes. Starting before the permit issues is charged double the fees. Call Building Safety at (310) 412-5294 to confirm the steps.
Do you need a permit to replace windows in California?
Permits come from each city, not the state, so the answer depends on where you live. Inglewood requires a Residential Alteration permit for same-size replacement, and Los Angeles treats a same-size change-out as an express permit. A contractor who says no permit is needed anywhere should be asked to put that in writing.
How much does it cost to replace windows in Los Angeles?
Vinyl replacement windows run about $550 to $1,200 each installed, and 10 to 15 windows cost about $14,000 to $28,000. Angi's Los Angeles page shows an average of $19,356, and the 2025 Cost vs. Value report lists vinyl replacement at $23,783. These are regional figures, not Inglewood quotes, and wood or fiberglass cost more.
How long does it take for new windows to be installed?
Installation usually takes less time than ordering. Made-to-order windows have a lead time that varies by manufacturer, so get it in writing, and a retrofit goes faster than a full-frame job that opens stucco. In Inglewood, work may run from 7 a.m. to 8 p.m. any day, and the permit inspection follows the install.
Are double pane windows required in California?
In practice, yes for replacements. Inglewood's handout caps replacement windows at a U-factor of 0.30 and an SHGC of 0.23, and single-pane glass cannot meet those numbers. Small areas of up to 75 square feet of glazing may use 0.40 and 0.35. Ask for the NFRC label on each window to confirm.
What do U-factor and SHGC ratings mean on replacement windows?
U-factor measures how quickly heat passes through the whole window, and SHGC measures how much solar heat enters. Lower numbers are better for both. In Inglewood's Climate Zone 8, a low SHGC on west and south walls matters most. Each window's certified values are printed on its NFRC label.
Do I need a permit to add an egress window in Inglewood?
Yes. Adding or enlarging an opening is more than a same-size swap, so the City asks for a scaled floor plan with window sizes, types and header sizes. A bedroom egress opening needs at least 5.7 square feet of net clear area, or 5.0 at or below grade, 20 inches of width, 24 inches of height and a sill no higher than 44 inches.
Will replacement windows reduce airplane noise in Inglewood?
They can help, but glass is only one path for sound. Ask for tested sound ratings in writing, and check the City's Residential Sound Insulation Department first, because eligible owners inside the 2020 Noise Exposure Contour Map can get grant-funded sound modification. Call 310-412-5289 or email soundinfo@cityofinglewood.org.
Does Inglewood pay for new windows near LAX?
Possibly. The Residential Sound Insulation Department uses FAA and Los Angeles World Airports grant funds for sound modification for eligible owners inside the 2020 Noise Exposure Contour Map. Eligibility depends on the address, so ask the department before you buy windows yourself. The presale report also states a property's LAX impact level.
Should I worry about lead paint when replacing windows in an older Inglewood house?
Yes, if the house was built before 1978. Inglewood's Housing Element flags lead-based paint across many of its older homes, and any paid work that disturbs paint in them falls under EPA's lead-safe rule. Ask the installer for lead-safe certification, and have a lab test old trim before it is cut, scraped or removed.
