Window Replacementin Highland, CA
Window replacement in Highland usually needs a permit: a City bulletin says one is needed in many cases, and the exempt list never names windows. Bedrooms must keep an escape opening, lots east of Weaver Street and north of Greenspot Road need a fire zone check, and 43.8 percent of homes predate 1980, so lead-safe rules often apply.
Highland's windows have seen a lot of sun. NOAA's 1991 to 2020 normals for Redlands, the nearest station with full normals, show about 104 days a year at or above 90 F, about 26 at or above 100 F and an August average high of 96.2 F, and the City's Safety Element defines an extreme heat day as one above 103 F, with 4 a year historically and 28 projected by 2050. The housing is mostly late twentieth century: 53.5 percent of 16,795 homes were built from 1980 through 2009, and the median owner-occupied home is worth $485,600, plus or minus $15,010.
This page covers the permit question first, then fire zone glass, bedroom escape openings, heat, older and historic homes, water at the opening and the schedule. Municipal Code text comes from GoCodebook's third-party mirror, and several City handouts cite 2019 or 2021 codes while the code now adopts 2025 editions, so confirm each point with Building & Safety. Price ranges are on our windows page.
Where Highland rules reach a window order
Where windows permits come from in Highland: City of Highland Building & Safety Division.
- Windows: the City's Homeowner Permit Tips bulletin (April 2017) says 'in many cases' a permit is needed to replace existing fixtures such as windows, while the Permit Exceptions page does not list window replacement as exempt; the City publishes a window flashing detail and tells owners to call the counter to confirm.
- Escape and rescue openings: the City's May 2017 bulletin says every sleeping room needs at least one escape and rescue door or window and gives minimum net clear opening tables; the diagram text reads 5.7 square feet (5.0 for a grade-floor window) with minimum width and height pairs, but the PDF layout is scrambled so the exact pairs are not stated here.
- Windows in the fire zones: the 2025 WUI Code adopted in Municipal Code 15.16 applies in very high fire hazard severity zones and WUI areas, and Highland's local additions listed in 15.16.030 do not include a separate window glazing rule; the City publishes no window-specific table on the pages read. (read in GoCodebook's third-party mirror of the Municipal Code, checked for window and fire zone rules, text as of 2026-10-04).
Do replacement windows need a permit in Highland?
In many cases, yes, and Highland never lists window replacement as exempt. The City's Homeowner Permit Tips bulletin, dated April 2017, says a permit is needed in many cases to replace existing fixtures such as windows, while the Permit Exceptions page names painting, tile and cabinets but not window change-outs. The City also publishes a window flashing detail and tells owners to call the counter to confirm.
We treat a change-out as permitted until the counter says otherwise. The state energy code requires certified dual glazing for replacement windows in residential buildings of three stories or less (Title 24, Part 6, section 150.2(b)1B, as the Los Angeles building department quotes it), and Highland adopted the 2025 Energy Code through Ordinance 477, so ask which labels the inspector wants to see. Permits can be filed through the iWorQ portal, a contractor declaration must come from the licensee or a person on the CSLB license, and a residential permit lapses if work does not start within 365 days.
What glass and frames do replacement windows need in Highland's fire zone?
The City's pages name no window rule, and that is the honest starting point. The very high fire hazard severity zone covers the northeastern corner and everything east of Weaver Street and north of Greenspot Road. The 2025 Wildland-Urban Interface Code applies there through Municipal Code 15.16, and Highland's local additions in 15.16.030 do not include a separate window glazing rule. The Old Fire of 2003 and the 2024 Line Fire, which began along Base Line near Alpine Street, explain why owners ask.
Elsewhere in California, fire zone checklists such as the one Los Angeles uses call for multilayer glazing with at least one tempered pane under California Building Code section 2406, and we price that option on any foothill lot. Whether it is required at your address depends on the zone map: the City posts the State Fire Marshal's March 25, 2025 map for adoption and we found no adoption date. The same code bars eave-type attic ventilators in the zone, which matters if soffit or eave work comes with the windows.
Do bedroom windows have to stay big enough to climb out of?
Yes. The City's May 2017 bulletin says every sleeping room needs at least one escape and rescue door or window, and it gives minimum net clear opening sizes. The bulletin's PDF layout is scrambled, so we do not print the width and height pairs; get them from the counter before you order a bedroom window.
A replacement can shrink an opening without anyone noticing. A thicker frame, a smaller sash or a slider swapped for a fixed-and-awning pair changes the net clear opening. We measure what is actually clear, not the rough opening, and ask whether the inspector will check it. The same question comes first on a garage conversion that adds a bedroom. Cutting a new opening into a wall is a different job, an alteration with plans, which the Highland room addition page covers.
How hot does Highland get, and which glass helps?
Hot enough to matter on the sunny side of a house. NOAA's Redlands normals, from a station about 5.5 miles south-southwest of the city center point at roughly 1,410 feet, give 12.87 inches of rain a year, 9.77 of it from December through March, highs from 66.6 F in January to 96.2 F in August, and about 3 days a year with lows at or below 32 F. Highland sits closer to the San Bernardino Mountains, at about 1,300 feet, so a foothill lot can run differently.
The City's plan check page lists Climate Zone 10, and the Safety Element says Santa Ana winds drive most wildfires in the region. Glass choices follow: dual-pane units with a low-e coating cut heat gain, and Angi's July 2026 Los Angeles page lists double-pane at $500 to $2,000 per window, low-e at $300 to $1,100 and tempered at $200 to $700. Those are Los Angeles survey figures, not Highland quotes. We choose coatings by exposure and look at the west and south walls first.
Do windows in older or historic Highland homes need lead-safe work or Planning review?
Both questions are real. About 43.8 percent of Highland homes, 7,358, were built before 1980, 22.2 percent before 1960 and 4.2 percent in 1939 or earlier. EPA's lead rule covers paid work that disturbs paint in homes built before 1978, and the Census table cannot separate 1978 from 1979, so your own build year decides. The City's permit application bulletin also has applicants acknowledge lead-safe practices for pre-1978 homes.
For historic review, Municipal Code 16.32.070 requires a certificate of appropriateness from the Historic and Cultural Preservation Board for alterations to designated resources and properties in historic districts, and 16.32.120 says ordinary maintenance that does not change design, material or external appearance is not blocked. A vinyl window in a wood-window house changes the material, so ask Planning first. We did not read the designated list or any window design guidelines, and the oldest houses cluster around the Historic Village District at Palm Avenue and Base Line.
How do rain, flashing and stucco repair work at a Highland window?
A window fails at its edges, not in its glass. The City publishes a window flashing detail, and its plan check page sets design rainfall at 2 inches per hour, ground snow load at zero and seismic design category D at minimum. Highland gets only about 12.87 inches of rain a year at the Redlands station, but when it comes, as the mud and debris flood of December 22, 2010 showed, it comes hard. A sill that is not flashed and sealed to the water barrier lets that rain behind the stucco.
A full-frame replacement opens the exterior, so stucco patching and paint matching belong in the quote. In a house built before 1978, lead-safe containment applies to that work too. A retrofit insert that keeps the old frame avoids most of the patching, while a new frame with a nailing fin needs the wall opened. Neither choice changes the permit question, so we describe the frame type when we call the counter.
How long does window replacement take in Highland, and who installs?
On our planning ranges, expect 1 to 2 weeks to measure and quote, 4 to 8 weeks of factory lead time once the order is placed and 1 to 3 days on site, with plan check added if the job needs it. Those are our estimates, not City or manufacturer figures, and the supplier gives the real lead time. Building inspections run Monday through Thursday, 8 a.m. to 5 p.m., plus alternate Fridays in the morning, and Municipal Code 15.48.020 bars construction before 7 a.m. or after 7 p.m. Monday through Saturday.
MDG Builders, CSLB #1040337, is the general contractor that measures, orders, permits and schedules the job, and a licensed glazing or window subcontractor installs the units; ask that firm for a license number and a certificate of insurance, and see the subcontractor chain explained. Skip any quote that leans on the federal 25C window credit, which the IRS says is not allowed for property placed in service after December 31, 2025. The license check guide shows how to verify a license.

What windows costs around Highland
The windows page puts vinyl replacement at about $550 to $1,200 per installed window and a whole house of 10 to 15 windows at about $14,000 to $28,000, with wood and fiberglass above that. Los Angeles sources bracket those figures. In the 2025 Cost vs. Value report from Remodeling magazine, a vinyl window job costs $23,783 and a wood one $27,913 there, recovering about 83.2 and 81.9 percent at resale, and Angi's July 2026 page gives an average of $19,356. None of those is a Highland quote, and the median owner-occupied home in town is worth $485,600. Fire zone 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. Window jobs close to Highland are on the pages for San Bernardino, Rialto, Fontana and Los Angeles. Windows for a backyard unit are on the Highland ADU page, a bath with new windows on the Highland bathroom page, new openings on the Highland room addition page, and the Highland area page lists every trade we cover here.

Highland window replacement questions, answered
Do I need a permit to replace windows in California?
Usually, yes, because Title 24 reaches replacement windows and most building departments want a permit for a change-out. Highland's Permit Exceptions page never lists windows as exempt and a City bulletin says a permit is needed in many cases, so we treat the job as permitted and confirm with the counter before ordering.
Do I need special fire-resistant windows if I live in a Highland fire zone?
The City's pages name no window glazing rule, but the 2025 Wildland-Urban Interface Code applies in the very high zone east of Weaver Street and north of Greenspot Road. Ask Planning whether your parcel is inside it. We price tempered or multilayer glass as an option on foothill lots in the meantime.
How much does it cost to have windows replaced?
Vinyl runs about $550 to $1,200 per installed window in our ranges, or $14,000 to $28,000 for 10 to 15 windows, and wood or fiberglass costs more. Los Angeles sources support the numbers, since we found no Highland survey, and fire zone glass, bigger openings and stucco repair can push a written quote higher.
How long does it take for new windows to be installed?
Installation takes 1 to 3 days on site, but custom units are built to size, so the factory lead time of roughly 4 to 8 weeks sets the schedule. Those are our planning ranges. Add a week or two to measure and quote, plus plan check if the City asks for one.
What do U-factor and SHGC ratings mean?
U-factor is the rate at which heat conducts through the whole window, and a lower number insulates better. SHGC, the solar heat gain coefficient, is the share of the sun's heat that passes through, and a lower number blocks more. Both sit on the National Fenestration Rating Council label. Highland is in Climate Zone 10, so ask the counter what the 2025 Energy Code expects.
Is replacing home windows worth it?
Often, though not for resale alone. Remodeling magazine's 2025 Cost vs. Value report, which covers Los Angeles and not Highland, shows vinyl replacement recovering about 83.2 percent of its cost at sale and wood about 81.9 percent. In a city with 104 days a year at or above 90 F, comfort counts too.
What are replacement windows, and how do they differ from a full-frame job?
Replacement windows are units made to fit an existing opening, and a retrofit insert keeps the old frame and trim. A full-frame job removes the frame, which allows new flashing and repairs but opens the stucco. Both usually need a permit in Highland, so tell the counter which one you mean.
Can I install a window myself?
You can as an owner-builder, but the City requires a property owner package and declaration, and the work must meet the same energy, flashing and escape opening rules. In a house built before 1978, lead-safe practices still matter. A tied-off ladder must be on site if the inspector needs roof access.
Do bedroom windows have to be big enough to escape through in Highland?
Yes, every sleeping room needs at least one escape and rescue door or window under the City's May 2017 bulletin. We do not print the minimum sizes because that bulletin's tables were unreadable, so get the numbers from Building & Safety before ordering a replacement that is smaller than the old one.
Do windows in a pre-1978 Highland home need lead-safe work?
Yes, when a paid contractor will disturb painted surfaces in a home built before 1978, EPA's rule applies. About 43.8 percent of Highland homes predate 1980, and the Census table cannot separate 1978 from 1979. Check your build year, and expect containment and cleanup to appear in a written quote.
