Window Replacementin Covina, CA
Window replacement in Covina needs a building permit even when the new windows match the old ones, and the express counter handles like-for-like swaps. Replacement windows must be dual glazed and meet the energy limits in the City's handout. About 76 percent of local homes predate 1980, so lead-safe rules usually apply.
Covina's windows are older than most owners assume. Census estimates count 38.6 percent of the city's homes as built before 1960 and roughly 76 percent before 1980, so many houses still carry original glass or a replacement from decades ago. The valley heat gives the glass real work to do: the Pomona station, the nearest with temperature normals, logs about 70 days a year at or above 90 degrees.
This page covers whether to repair or replace, the permit rule for same-size swaps, glass ratings, bedroom egress, the southeast fire zone, lead-safe work, condos and rentals, and what the City does and does not regulate for historic windows. Price ranges and the phase timeline are on our windows page.
Covina Building and Safety rules that apply to window work
Where windows permits come from in Covina: City of Covina Community Development Department, Building and Safety Division.
- Covina requires a building permit for a window or door change-out even when it is like for like (Handout #07, effective 1/1/2026); the express permit counter handles like-for-like replacements, and two floor plan sets plus an 8.5 by 11 site plan are required, with structural details and calculations by a licensed professional if the opening is made larger.
- New or replacement windows installed in Covina must be dual glazed and meet Energy Code Table 150.1-A maximum U-factor 0.30 and maximum SHGC 0.23; replacement fenestration of the same total area must meet the Energy Code's replacement requirements (Section 150.2(b)1B).
- If the opening, sill height or wall finish of a window in a sleeping room, basement or habitable attic is altered, an emergency escape and rescue opening is required: at least 5.7 square feet net clear (5.0 at grade), 24 inches clear height, 20 inches clear width and a sill no higher than 44 inches (CRC R319).
- Changing a window or door location, even like for like, needs Planning Approval Clearance before the building permit in Covina, according to the Building and Safety page.
- EPA's lead rule treats window replacement as always covered in pre-1978 housing, regardless of square footage; about 76.2 percent of Covina's housing units were built before 1980.
- CSLB defines the C-17 Glazing classification as selecting, cutting and installing glass, mirrors and glass substitutes and building and glazing frames, panels, sashes and doors.
Should you repair or replace the windows in a 1950s or 1960s Covina house?
Start by separating the glass from the frame. If the frames are sound and the problem is fogged glass, drafts or a stuck sash, an insert that fits inside the existing frame keeps the stucco and trim untouched. If the frames are warped, cracked or leaking at the corners, a full-frame replacement removes the old frame, and that means patching stucco and trim around it. The choice changes the price more than the glass does.
Ask the contractor to say in writing which method each opening gets, and to photograph the sill and corners once the old unit is out. Water damage in the framing beneath a window is a discovery item, and a unit price agreed in the proposal keeps it from stalling the job.
CSLB defines the C-17 Glazing class as selecting, cutting and installing glass and building and glazing frames, panels, sashes and doors. MDG Builders, CSLB #1040337, writes the scope, pulls the permit and schedules the work, while a licensed glazing or window subcontractor does the installation, and you can ask for that firm's license number and certificate of insurance.

- Who patches the stucco and paints the trim?

Do you need a permit to replace windows in Covina?
Yes, even for a like-for-like swap. The City's window change-out handout (number 07, effective January 1, 2026) requires a building permit for a window or door replacement of the same size and type, and the Building and Safety page says like-for-like replacements are handled at the express counter. Plan on two sets of floor plans and an 8.5 by 11 inch site plan; if the opening gets larger, structural details and calculations from a licensed professional are added.
Moving or adding an opening is a bigger step. The Building page says a window or door location change, even like for like, needs a Planning Approval Clearance before Building accepts the plans, and plans without it may be rejected. A different window style on the street side is worth a call to Planning at (626) 384-5450 as well.
We read the Municipal Code on the gocodebook.com mirror (2026-10 edition), not the City's official code site, and we did not read the handouts numbered 04, 06, 11 to 17, 19 or 21 to 31, so ask the counter whether another handout applies. The Building and Safety page lists the current rules.
Dual glazing, U-factor and SHGC for replacement windows in Covina
The City's handout says new and replacement windows must be dual glazed and meet the Energy Code's Table 150.1-A limits, listed as a maximum U-factor of 0.30 and a maximum solar heat gain coefficient (SHGC) of 0.23, and it cites Section 150.2(b)1B for replacement of the same total area. U-factor measures how fast heat moves through the window, and SHGC measures how much sun heat comes through the glass. The numbers are on the window's label.
California adopted a new Energy Code on January 1, 2026, and window numbers differ between cities and climate zones, so ask the counter whether the handout's limits are current for your job and ask the seller to show the label rating on the quote. The City places Covina in Energy Climate Zone 9.
The heat is why the SHGC number deserves a look. NOAA's Pomona normals show an August high of 92.4 degrees, 70.5 days a year at or above 90 and 10.7 at or above 100, so a west-facing living room window works hardest between June and September. Ask which windows face west or south and whether the glass spec changes by elevation.
Bedroom egress windows in Covina: how big the opening has to be
If the opening, sill height or wall finish of a window in a sleeping room, basement or habitable attic is altered, the City's handout requires an emergency escape and rescue opening under CRC R319. It must provide at least 5.7 square feet of net clear opening (5.0 at grade), at least 24 inches of clear height, at least 20 inches of clear width and a sill no higher than 44 inches.
Net clear opening is the part you can actually climb through once the sash is open, so it is smaller than the window's nominal size. A double-hung window can fail the height or area test even when the frame looks big enough. Ask the contractor to confirm the net clear numbers from the manufacturer's data for each bedroom and to write them on the plan.
Swapping a bedroom window for a smaller one to fit a vanity, a bed or a kitchen counter is the usual way a house falls out of compliance. The handout ties the rule to altered openings, so a same-size swap does not trigger it, but ask the counter how it reads your job.
Replacement windows near Covina's southeast fire zone
Roughly 3.8 percent of the city, concentrated in the southeast corner, lies within a CAL FIRE Very High zone on the state's older Local Responsibility Area layer, which we screened against the city outline. The City's design criteria handout says areas of Covina are in Very High zones, and chapter 14.11 of the code adopts the 2025 Wildland-Urban Interface Code.
What we could not confirm is whether a window-only job in one of those zones triggers extra glazing rules. Los Angeles, for one, lists multilayer glazing with at least one tempered pane in its fire-zone checklist, but that is the City of Los Angeles, not Covina. Ask Building and Safety whether your parcel is in a zone and whether the 2025 WUI Code reaches a window replacement.
The City's own zone map, held by the City Clerk, governs, and the state layer we used is older. A parcel on the edge of the southeast corner deserves a written answer from the City, not a salesperson's guess. Fire-zone work can also change the frame material and glass spec, and therefore the price, so get the answer before the quote.
Lead-safe rules, order lead times and install day for Covina windows
EPA's lead rule always covers window replacement in housing built before 1978, whatever the square footage, and about 76 percent of Covina's homes were built before 1980. Paid firms, including general contractors, must be EPA-certified and work lead-safe, with containment, a cleaning verification and a record. Ask for the firm's certificate before demolition.
The counter is open Monday to Thursday, 7:00 a.m. to 6:00 p.m., closed 1 to 2 p.m. and closed Friday through Sunday, and an express permit shortens the wait. Inspections are requested by email to bldinspections@covinaca.gov. Ask the seller for the manufacturer's current lead time in writing, because custom sizes are made to order and the permit often finishes before the windows do.
California's contract law (Business and Professions Code 7159) requires a written contract over $500 with the license number, caps the down payment at $1,000 or 10 percent of the price, whichever is less, and ties progress payments to work done. If a salesperson asks for more at the kitchen table, that is the number to quote. Our license check guide shows how to verify the firm.
Windows and sliding doors in Covina condos, rentals and the downtown area
About 41.2 percent of Covina's occupied homes are rented and 25.7 percent of units sit in buildings of five or more units. The window handout covers doors too, so a sliding glass door follows the same permit path. In a condominium or townhome common area, the City asks for a letter of authorization from the HOA president, and a tenant can pull a permit only as an authorized agent, with a notarized letter from the owner.
Historic review is narrower than some websites claim. Covina's historic chapter reaches only owner-nominated landmarks and structures of merit, and the Los Angeles Conservancy's page says the City had designated none, relying on a downtown survey from 2007. We found no downtown historic overlay in the code or on Planning's page, so ask Planning for the current landmark list if your house is old.
Downtown is different in another way. Planning lists the Covina Town Center Specific Plan, a Mixed-Use Overlay District and the Covina Design Guidelines, and inside a specific plan area that plan's standards govern. A storefront or a front-facade window there should be checked with Planning before it is ordered.

What windows costs around Covina
Our windows page puts 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. Those ranges sit between Remodeling magazine's 2025 Cost vs. Value report for Los Angeles (vinyl replacement at $23,783, recouping about 83.2 percent at resale), Angi's Los Angeles page updated in July 2026 (an average of $19,356) and a ConsumerAffairs page that states no method. None is a Covina quote, and the City fee schedule was not opened, so the permit fee is a separate line in the written proposal. Rules change at the city line, so compare window replacement in West Covina, Baldwin Park, Pomona and Los Angeles. Window changes in the wall of a new room also belong on our Covina room addition page.

|---|---|
| Vinyl window, installed, each | $550 to $1,150 |
| Wood or fiberglass window, installed, each | $950 to $2,400 |

Covina window replacement questions, answered
Do I need a permit to replace windows in Covina?
Yes, even for a same-size swap. The City's window handout requires a building permit for a window or door change-out of the same size and type, and the express counter handles like-for-like work. Moving or adding an opening needs a Planning Approval Clearance first. Call Building and Safety at (626) 384-5460 with your address before you order.
How much does it cost to replace windows in California?
Vinyl replacement windows run about $550 to $1,200 each installed, and a whole house of 10 to 15 windows about $14,000 to $28,000, with wood and fiberglass costing more. Those figures come from Los Angeles sources, not Covina. Frame material, glass spec, stucco patching and any fire-zone requirements move the total.
Are double pane windows required in California?
In Covina, yes: the City's handout requires new and replacement windows to be dual glazed and meet the Energy Code limits it lists. It cites a maximum U-factor of 0.30 and SHGC of 0.23. Because California adopted a new Energy Code on January 1, 2026, ask the counter whether those limits are current for your job.
Do I need special fire-resistant windows if I live in a Covina fire zone?
Possibly, and we could not confirm it for a window-only job. About 3.8 percent of Covina, in the southeast corner, sits in a Very High zone on the state's layer, and the City adopted the 2025 Wildland-Urban Interface Code. Ask Building and Safety whether your parcel is in a zone and whether that code reaches window replacement.
How long does it take for new windows to be installed?
The installation itself is short compared with the waits around it. Plan for the permit, which an express counter can shorten, and for made-to-order windows to arrive. Ask the seller for the manufacturer's current lead time in writing, and ask how many days the crew expects to be on site once the windows are delivered.
Are replacement windows worth it?
It recoups most of its cost at resale in the one regional study we found. Remodeling magazine's 2025 Cost vs. Value report for Los Angeles shows about 83.2 percent for vinyl and 81.9 percent for wood. We found no Covina resale study, and we make no energy-savings claim because no source we trust gave a local figure.
Do I need an egress window in a bedroom?
Yes, when you alter the opening, sill height or wall finish of a sleeping room, basement or habitable attic. The City's handout requires 5.7 square feet of net clear opening (5.0 at grade), 24 inches of clear height, 20 inches of clear width and a sill no higher than 44 inches. A same-size swap does not trigger it.
Is there a tax credit for replacement windows in 2026?
Not the federal one. The IRS says the Energy Efficient Home Improvement Credit under section 25C is not allowed for property placed in service after December 31, 2025, although many older web pages still advertise it. We did not verify any state or utility rebate for Covina, so ask your utility before you count on one.
