Window Replacementin San Bernardino, CA
Window replacement in San Bernardino is treated as permitted work, though the City never lists it as exempt. In foothill and very high fire zones, vinyl frames need welded corners and dual-pane glass with one tempered pane. About 62.6 percent of homes predate 1980, so lead-safe rules often apply.

San Bernardino's windows have a lot of weather behind them. The Census Bureau's 2024 estimates put 62.6 percent of the city's 68,594 homes before 1980, and about 9 percent in 1939 or earlier, so plenty of frames are single-pane originals or early aluminum swaps. The City's Housing Element says at least half the stock is 50 years old or more, and the median owner-occupied home is worth $461,400, plus or minus $16,338. Heat, Santa Ana wind and a mountain wildfire edge make glass choices more local here than in most inland cities.
This page covers fire-zone glass first, then the permit question, heat, lead-safe work, historic questions, airport noise and the schedule. Municipal Code quotes below come from GoCodebook's third-party mirror, since the City's own code host turned our tools away, and the Building & Safety Division has the final word on each one. The price ranges are on our windows page.
Where San Bernardino rules reach a window order
Where windows permits come from in San Bernardino: City of San Bernardino Community Development & Housing Department, Building & Safety Division.
- Windows: the City's exempt-work list does not mention window replacement and the 07/2020 fee schedule carries a window change-out line, so a change-out is treated as permitted work (confirm at the counter); in the foothill and very high fire zones replacement vinyl windows must have welded corners, metal-reinforced interlocks, dual-pane glass with at least one tempered pane and AAMA lineal certification, and in Building Safety Enhancement Areas exterior glazing must be tempered or multi-layered glass. (read in GoCodebook's mirror, text as of 2026-10-04)
- The 07/2020 fee schedule lists window change-outs in its valuation table, but the PDF layout is scrambled and the per-window figure cannot be read reliably, so no price is quoted here.

What kind of glass does San Bernardino require for replacement windows in a fire zone?
Where the foothill or very high zone applies, Municipal Code 15.10.080 sets the rule for vinyl frames: welded corners, metal reinforcement in the interlock area, dual-pane glass with at least one tempered pane and AAMA lineal certification. In Building Safety Enhancement Areas, which the Council designates after a fire or applies to new tracts and large new commercial buildings, exterior glazing must be tempered or multi-layered glass. We read the foothill rule for vinyl only, so ask the Building Division what it wants on aluminum, fiberglass or wood frames.
Which lots are covered is the open question. The San Bernardino County Fire District adopted Ordinance 4489 on June 10, 2025 for Moderate, High and Very High zones in its Local Responsibility Areas, while Municipal Code 15.10.030 still names the City's very high zone map dated October 29, 2008, and we could not tell which parcels each map covers. Retrofit thresholds disagree as well: Municipal Code 15.10.040 says 60 percent of an element and the Development Code says 25 percent, and the pages we read name roofing and fencing, not windows. The District's fire hazard map viewer shows an address.
- Which map does the counter use for my parcel, the County's 2025 one or the City's 2008 one?
- Is the frame vinyl, aluminum or wood, and does the glass have one tempered pane?
- Does the supplier certify the vinyl lineal to AAMA, with paper to show the inspector?

Do replacement windows need a permit in San Bernardino?
Probably, though the City never says so outright. Its exempt list names painting, tiling, cabinets, countertops, awnings projecting no more than 54 inches and one-story sheds up to 120 square feet, but not windows, and its 07/2020 fee schedule carries a window change-out line, so we treat a change-out as permitted work and confirm it at the counter. The PDF's columns are scrambled, so we quote no per-window fee. A contractor needs a state license and a current City business license, and a larger opening is a structural change, which the City says needs a building permit with plans filed in person at 201 North E Street.
Efficiency is the other half of the permit. Municipal Code 15.04.020 adopts the 2025 California codes, Energy Code included, and its Part 6 section 150.2 sets the glass numbers for replacement windows. California city handouts disagree on those numbers by climate zone, so we ask for the NFRC label and the supplier's compliance sheet instead of printing a figure. Window glass belongs to a bath job too, and the San Bernardino bathroom page covers bath-side questions.

How hot does San Bernardino get, and what glass helps?
Hotter than the coast and drier than most of California. NOAA's 1991 to 2020 normals for Redlands, the nearest full station, about 9 miles southeast and on higher ground, give an average August high of 96.2 F, about 104 days a year at or above 90 F and about 26 at or above 100 F. The valley floor sits lower than that station, so a west wall may run hotter. Rain totals 12.87 inches a year, 9.77 inches of it from December through March, and the 2024 Local Hazard Mitigation Plan describes high-velocity, dry Santa Ana winds in the fall.
Glass choice follows. Dual-pane, low-E glass with a low solar heat gain number is the usual answer to long hot summers, and the NFRC label states both the U-factor and the solar heat gain coefficient for each window. Angi's July 2026 Los Angeles page lists low-E coatings at $300 to $1,100 per window and tempered glass at $200 to $700, so both are real price lines. We found no source on sun exposure by San Bernardino street, so we judge it on site, wall by wall.

Do window replacements in pre-1980 San Bernardino homes need lead-safe work?
Often, and the numbers explain why. About 62.6 percent of San Bernardino homes were built before 1980 and 36.9 percent before 1960, and EPA's lead renovation rule covers paid work that disturbs paint in houses, apartments and child-occupied facilities built before 1978, sole proprietors included. Old sashes and trim are classic painted surfaces. The Census table cannot split 1978 from 1979, so your own build year decides, and an owner working on their own home is generally outside the rule.
Rentals add a second prompt. The City estimates 30 percent of single-family homes are rentals, inspected every two years, and exterior condition items such as windows can come up after a notice. Opening a wall around an old frame can also expose old materials, and South Coast AQMD Rule 1403 sets asbestos practices for renovation and demolition. Ask the installer for EPA lead-safe certification before measuring day, and confirm any license with our license check guide.

Can I replace the original wood windows in an older San Bernardino house?
Probably, because there is no adopted historic overlay to stop you. The Historic Preservation chapter of the Development Code, 19.18, is still marked reserved for a future ordinance in the October 2019 edition we read. The City's one historic tool is Municipal Code 15.37, which requires a permit and a Planning Commission process to demolish a building 50 years old or older, and a historic resource evaluation report for buildings on the 1991 reconnaissance survey, which covers structures built before December 31, 1941, or in survey-identified potential districts.
We read nothing that governs window replacement on a surveyed building, and we did not open the survey list, so ask Planning before ordering anything for a prewar house. Repairing old sashes is another option. In the foothill zones, the no-exposed-wood rule carries an exception for openings, and the text we read does not say what that covers for wood windows, so that is a second question for the counter.

Do airport noise zones or large openings change a patio door or window order?
Near the former Norton Air Force Base, possibly. Development Code 19.12 creates Airport Districts I and II as rectangles off the runway ends and Districts III to V as the 75 to 80, 70 to 75 and 65 to 70 Ldn noise bands around San Bernardino International Airport, and its stated aim is to limit crash hazard and high noise exposure. We found no window-specific noise requirement in the text we read, so sound-rated glass is a choice to price, not a code line we can cite.
Bigger openings raise other issues. A sliding door or a widened window is a structural change, so expect plans, a header and possibly an engineer. Bedroom egress sizes and safety-glass locations come from the state building code, which we did not read for this page, so we print no dimensions and expect the installer to state them on the order.
- Is the airport noise band shown on the parcel map I received?
- Who states the egress size and safety-glass spots on the order?
- Does a wider opening need a header and an engineer's letter?

How long does window replacement take in San Bernardino, and who installs?
Our planning ranges are 1 to 2 weeks to measure and quote, plan check if the job needs it, 4 to 8 weeks for the factory to build to size and 1 to 3 days of installation. Those are our estimates, not City or manufacturer figures, and the supplier quotes the real lead time. Municipal Code 15.04.050 treats a permit with no inspection and no substantial progress in any 180-day period as abandoned, and Municipal Code 8.54.070 bars construction work before 7 a.m. and after 8 p.m.
MDG Builders, CSLB #1040337, is the general contractor that measures, orders, permits and schedules the job, and a licensed glazing or window subcontractor does the installing. Ask that firm for its license number and a certificate of insurance, and see the subcontractor chain explained. Older articles still advertise a federal window tax credit, but the IRS says the 25C credit is not allowed for property placed in service after December 31, 2025.

What windows costs around San Bernardino
On our windows page, vinyl replacement runs roughly $550 to $1,200 per installed window, and a whole house of 10 to 15 windows roughly $14,000 to $28,000, with wood and fiberglass costing more. Los Angeles sources bracket those figures. Remodeling magazine's 2025 Cost vs. Value report prices a vinyl window job at $23,783 and a wood one at $27,913 there, recovering about 83.2 and 81.9 percent at resale, and Angi's July 2026 page for that city gives an average of $19,356. None is a San Bernardino quote, and the median owner-occupied home here is worth $461,400. Fire-zone frames and tempered glass, a larger opening and stucco patching can each raise a quote, and any permit charge appears as its own line in a written proposal. For comparison see windows in Riverside, Corona, Jurupa Valley, Moreno Valley and Los Angeles. Windows for a backyard unit are on the San Bernardino ADU page, new openings on the San Bernardino room addition page, and the San Bernardino area page lists every trade we cover here.

|---|---|
| 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 |

San Bernardino window replacement questions, answered
Do I need a permit to replace windows in California?
Usually, yes. The state energy code covers replacement windows, and most building departments treat a change-out as permitted work. San Bernardino's exempt list does not name windows and its fee schedule has a change-out line, so we treat it as permitted and confirm at the counter before ordering.
Do I need special fire-resistant windows if I live in a San Bernardino foothill fire zone?
Likely, yes. In the foothill and very high zones, vinyl frames need welded corners, metal-reinforced interlocks, AAMA lineal certification and dual-pane glass with at least one tempered pane. Which parcels count is unsettled between the County's 2025 map and the City's 2008 map, so check the address first.
How much does it cost to have windows replaced?
Our range for vinyl is about $550 to $1,200 per installed window, or $14,000 to $28,000 for 10 to 15 windows, with wood and fiberglass higher. It rests on Los Angeles sources, not a San Bernardino survey, and fire-zone glass, larger openings and stucco repair can raise a written quote.
How long does it take for new windows to be installed?
Installation takes 1 to 3 days, but ordering is the long part. Plan 1 to 2 weeks to measure and quote and 4 to 8 weeks for the factory to build to size. Those are our planning ranges, so ask the supplier for the actual lead time in writing.
What do U-factor and SHGC ratings mean?
U-factor measures how fast heat passes through a window, so lower is better insulation. SHGC, the solar heat gain coefficient, measures how much sun heat comes through, so lower blocks more. Both appear on the NFRC label. We do not print target numbers because California city handouts disagree by climate zone.
Is replacing home windows worth it?
Partly. Remodeling magazine's 2025 Cost vs. Value report for Los Angeles shows vinyl window replacement recouping about 83.2 percent at resale, and wood about 81.9 percent. We found no San Bernardino resale study, and summer heat here makes glass quality a comfort question as much as a resale one.
What are replacement windows, and how do they differ from a full-frame job?
A replacement window, often called an insert or retrofit, fits inside the existing frame, so stucco and trim stay mostly untouched. A full-frame job removes the old frame, which allows flashing repair and a new size but usually means stucco or trim patching. In a fire zone the frame rules still apply.
Can I install a window myself?
Sometimes. The City allows a homeowner to pull a permit for a house they live in, if they do the work personally and employ no one. The glass and frame must still meet the energy code, and in a fire zone the frame rules apply, so a mistake is costly to redo.
