Window Replacementin Camarillo, CA
Window replacement in Camarillo needs a building permit, according to the City's permit handout, and the City's Window Energy Form allows a U-factor of 0.30 and a solar heat gain coefficient of 0.23 at most for alteration windows. The form cites the 2022 energy code, so confirm the current values with Building & Safety before ordering glass.
Camarillo's windows are mostly as old as its houses. The Census Bureau's 2024 one-year estimates put about 44.7 percent of the city's 27,476 homes before 1980 and 70 percent in the 1960s through the 1990s, so many frames have been in the wall for decades unless someone replaced them. The City's own General Plan describes a Mediterranean climate with fall Santa Ana winds from the northeast and Pacific fog about ten miles west.
This page runs in the order a window job runs: the permit, the energy form, the fee lines, walls near a lot line, location hazards, protected buildings, and what a frame swap does to stucco and paint. The City's own pages and PDFs read normally, while the Municipal Code came from GoCodebook, a third-party mirror that is not the official code. Phases and price ranges are on our window replacement page.
City of Camarillo rules that apply to window replacement
Where windows permits come from in Camarillo: City of Camarillo Community Development Department, Building & Safety Division.
- Changing out windows requires a building permit, per the City's permit handout, and the City lists a Window Energy Form (Certificate of Compliance for prescriptive residential alterations, 2022 energy code) on its Handouts page.
- The Window Energy Form shows the prescriptive maximums of a 0.30 U-factor and a 0.23 solar heat gain coefficient (SHGC) for alteration windows, with a table for orientation and proposed area; the form cites the 2022 code, so confirm the current values.
- Exhibit F lists Windows, Doors and Skylights at $584 for up to 5 (new or alteration) plus $121 each additional, and $296 for up to 10 (retrofit or repair) plus $124 for each additional 5, before surcharges; the schedule does not say which line applies to a like-for-like replacement, so ask the counter.
- Section 10.34.120(E) treats window and similar construction noise like other construction: not between 7 PM and 7 AM and not on Sundays or listed holidays in or next to a residential zone.
- The City's Bathroom handout says each pane of glazing in a hazardous location under CRC R308.4 (such as near tubs and showers) must carry the manufacturer's designation, which applies when replacing bathroom windows.
- Fire separation: walls within 3 feet of the property line may have no openings, and walls 3 to 5 feet away are limited to 25 percent openings, which limits window changes on side walls close to a lot line (handout dated 01/31/08).
- For a designated or proposed landmark, windows are part of the protected exterior: Section 16.42.020 defines exterior architectural features to include 'the type and style of all windows, doors, lights', and no alteration permit issues for a proposed landmark until the City Council decides on designation (Section 16.42.060).

Do you need a permit to replace windows in Camarillo?
Yes. The City's When Do I Need a Permit handout lists changing out windows next to replacing a furnace or air conditioner, a water heater and roof coverings. It lists no permit for cabinets, tiling, carpeting, painting or a plug-in window air conditioner. Because the handout names the work, it is the first thing to quote when someone says a like-for-like swap is exempt.
Applications go through the OpenGov portal, since the City stopped taking paper plans on July 1, 2025. Section 16.04.045 of the Municipal Code, on the GoCodebook mirror, makes the investigation fee equal to the permit fee when work starts without a permit. An issued permit lapses if work does not begin within 12 months. Describe the scope, the number of openings and whether any opening changes size when you call Building & Safety at 805-388-5395.
What do the U-factor and SHGC numbers on Camarillo's Window Energy Form mean?
The City lists a Window Energy Form on its handouts page, a Certificate of Compliance for prescriptive residential alterations. It shows maximums of a 0.30 U-factor and a 0.23 solar heat gain coefficient, or SHGC, for alteration windows, with a table for orientation and proposed area. U-factor measures how fast heat leaks through the whole window, and SHGC measures how much solar heat passes through the glass. For both, a lower number means less heat gets through.
The form cites the 2022 energy code, while Section 16.04.010 adopts the most current edition of the state codes as amended by Ordinance 2034 of November 12, 2025. Those are in conflict until the counter says which edition governs, so do not order glass from the 2022 numbers alone. Ask every supplier for the National Fenestration Rating Council label on each unit, because the label is where the two ratings are printed.
How much is a permit to replace windows in Camarillo?
Exhibit F of the 2026 Master Fee Schedule has two lines. Windows, Doors and Skylights in new or alteration work cost $584 for up to 5 plus $121 for each additional one. A retrofit or repair line costs $296 for up to 10 plus $124 for each additional 5. The schedule does not say which line a like-for-like replacement uses, so ask the counter.
Arithmetic shows why the answer matters. For 12 openings, the first line gives a $1,431 base fee, which is $584 plus seven at $121, and the retrofit line gives $420. Both are base figures before the 11.34 percent technology surcharge and, on some items, the 17.89 percent General Plan surcharge. Section 10.34.120(E) bars window and similar construction noise next to a residential zone from 7 PM to 7 AM and on Sundays and listed holidays.
Can you change windows on a wall close to the property line in Camarillo?
Sometimes the answer is no. The City's exterior wall handout, dated January 31, 2008 and written to the 2007 building code, says an R-3 wall 5 feet or more from the property line may have unlimited openings, a wall 3 to 5 feet away needs 1-hour construction and openings up to 25 percent of the wall, and a wall under 3 feet allows none. The handout is old, so confirm the edition with Building & Safety.
The R-1 zone requires side yards of at least 5 feet for a one-story house and 10 feet for a two-story one, so most original side walls sit at or past the first breakpoint. The risk is a house with an addition, a garage wall or a tight corner lot. Swapping a window the same size in the same wall is a smaller question than enlarging an opening, and a new opening on a side wall is where a plan checker looks first.
Do fire zones, airport noise or Santa Ana winds change which windows to buy?
They can. The hills along the northern and eastern edges sit in CAL FIRE's Very High, High and Moderate zones and Camarillo Springs is in the Very High and High zones, according to the City's September 2025 Safety Element. Camarillo adopts the California Wildland-Urban Interface Code, and the Safety Element says Chapter 7A applies in those areas. We did not read the glazing rules in that chapter, so ask Building & Safety what a window swap on your lot must meet.
Noise is a second location question. Camarillo Airport sits inside the city, and the Safety Element says the 60 CNEL noise contour from Naval Air Station Point Mugu covers a small part north and west of Pleasant Valley Road, south of U.S. 101. NOAA's 1991 to 2020 normals for the airport station show 12.01 inches of rain a year, 9.46 of it from December through March, and about 9.0 days at or above 90 F, most in September and October. Ask for flashing and sealant details meant for wind-driven rain.
Replacement windows in Old Town, a designated landmark or a Spanish-style home
Chapter 16.42 treats windows as part of a landmark's protected exterior. Section 16.42.020 defines exterior architectural features to include the type and style of all windows, doors and lights, and Section 16.42.060 says no alteration permit issues for a proposed landmark until the City Council decides on designation. The Planning Commission acts as the landmark committee. We found no list of designated landmarks or districts in the sources we read, so ask Planning before you assume a building is not on one.
Old Town, along Ventura Boulevard between Lewis Road and Carmen Drive, is the original commercial district and the COT zone, enacted in 1998 to preserve its character, with small lots and mostly one-story buildings. The freeway-side Heritage Zone asks for Mission, Monterey, Spanish or Mediterranean styles, and Section 19.41.020 makes new homes there choose Spanish Colonial Revival or Monterey. That chapter targets new construction, so window style on a replacement is a question to ask, not a rule we can quote.
Retrofit or full-frame replacement: what happens to stucco, paint and lead?
A retrofit insert goes inside the existing frame and leaves the stucco alone, while a full-frame replacement removes the frame and nails fin, so the exterior finish has to be cut and patched. Replacing wood siding or stucco needs its own permit in Camarillo, listed at $219 flat in the fee schedule before surcharges. Bathroom windows near tubs and showers must carry the manufacturer's safety glazing designation on every pane, per the City's bath handout.
In a house built before 1978, paid work that disturbs paint falls under EPA's Renovation, Repair and Painting rule, and window replacement is the job the small-job exemption does not cover. The Housing Element notes lead-based paint risk in those homes. The federal 25C window tax credit does not apply to property placed in service after December 31, 2025, so older articles that advertise it are out of date.

What windows costs around Camarillo
For vinyl replacement windows we use about $550 to $1,200 each installed, and about $14,000 to $28,000 for a whole house of 10 to 15 windows, with wood and fiberglass costing more; the method is on our window replacement page. Three outside sources overlap in that area. Remodeling magazine's 2025 Cost vs. Value report for Los Angeles lists $23,783 for a vinyl window job, with 83.2 percent recovered at sale, and $27,913 for wood at 81.9 percent. Angi's Los Angeles page, updated July 2026, shows an average near $19,356 and a typical $16,359 to $22,377. ConsumerAffairs publishes the per-window ranges but no cost method. None is a Camarillo bid. Fire-rated frames, tempered or laminated glass, custom shapes and stucco patching raise a quote, and permit fees appear on their own line. MDG Builders, CSLB #1040337, manages the job as a general contractor, and a licensed glazing or window firm does the installation; ask for its license number and certificate of insurance. See how general contractors use subcontractors and how to check a contractor license. For nearby cities, see Oxnard, Thousand Oaks, Simi Valley and Los Angeles. In Camarillo we also handle bathroom remodeling, ADU construction and the room addition, and the Camarillo area page lists every trade.

Camarillo window replacement questions, answered
Do I need a permit to replace windows in Camarillo?
Yes. The City's permit handout lists changing out windows among the work that needs a building permit, and it keeps a Window Energy Form on its handouts page. Filing is through the OpenGov portal. Call Building & Safety at 805-388-5395 with the number of windows and whether any opening changes size.
How much is a permit to replace windows in Camarillo?
The 2026 fee schedule lists $584 for up to 5 windows plus $121 each additional in new or alteration work, and $296 for up to 10 plus $124 per additional 5 in retrofit or repair work. The schedule does not say which applies to a like-for-like swap. Both lines are base fees before surcharges.
How much does it cost to replace windows in California?
We use about $550 to $1,200 per vinyl window installed, so a whole house of 10 to 15 windows runs about $14,000 to $28,000, with wood and fiberglass costing more. Those figures rest on Los Angeles sources and overlap at roughly $19,000 to $24,000 for a typical house. Only a written proposal sets your price.
What do U-factor and SHGC ratings mean?
U-factor measures how quickly heat passes through the whole window, and solar heat gain coefficient, or SHGC, measures how much sun-driven heat passes through the glass. Lower is better for both. The City's Window Energy Form allows at most 0.30 and 0.23 for alteration windows, citing the 2022 code, so confirm current values.
Are replacement windows worth it?
Partly. Remodeling magazine's 2025 Los Angeles report shows a vinyl window job recovering about 83.2 percent of its cost at sale and wood about 81.9 percent. Camarillo's median owner-occupied home is valued at $871,300, and no local resale study turned up, so treat the figure as a regional guide, not a promise.
Do I need a permit to add an egress window?
Probably, because a new or enlarged opening changes the wall, and Camarillo's handout lists window change-outs as permit work. We did not read the egress size rules from the adopted code, so no dimensions are printed here. Ask Building & Safety for the current requirement, and expect a structural header and plans.
Can a handyman install my windows?
Only if the work needs no permit, and a Camarillo window change-out does need one. California lets an unlicensed person do jobs totaling $1,000 or less only when no permit is required and the person employs no one. Above that, or with a permit, hire a licensed contractor and look up the license.
Can I install a window myself in Camarillo?
The City's older FAQ, written before the online portal, says either the owner or a licensed contractor may apply for a permit. The job still has to pass inspection, meet the energy form and satisfy the lot-line wall rules. Flashing and sealing are where do-it-yourself installs usually fail, so photograph each step for the inspector.
Is there still a federal tax credit for new windows?
No for work finished after 2025. IRS guidance on the 2025 tax law ends the 25C home improvement credit for windows installed after December 31, 2025, and many older articles still advertise it. We did not verify any utility or state rebate that applies in Camarillo.
How long does it take for new windows to be installed?
Install time depends on the number and type of openings, and we found no sourced lead time for orders, so ask each supplier for one in writing. Stock sizes ship faster than custom shapes. Book the permit first, keep the inspection windows of 9 to noon and 1 to 4 in mind, and plan around Sunday and evening noise limits.
