The LA Window Replacement Permit Process: What Actually Happens (And Who Does It)
Every window replacement in LA requires a permit — no like-for-like exemptions. The permit generates the Title 24 compliance record (CF1R/CF2R), the inspection record required for title transfer and insurance claims, and puts the contractor on the hook for the work. Skipping it creates a sale-blocking problem. Six steps: spec lock → application → plan check (1–21 days by jurisdiction) → permit issued → installation → final inspection. We pull the permit.
Every window replacement in every LA jurisdiction requires a permit. Not most, not the complicated ones — every one. There is no like-for-like exemption, no size threshold, no contractor-only carve-out. If you are swapping a window in the City of LA, Beverly Hills, Pasadena, Santa Monica, Burbank, Glendale, Malibu, or any other jurisdiction we work in, a permit is part of the job.
The permit does three things that matter. First, it generates the Title 24 compliance record — the CF1R and CF2R forms that document NFRC ratings and confirm installed windows match what was permitted. Without that record, a HERS rater cannot sign off on the building. Second, it creates the inspection record that the title company, your insurance carrier, and any future buyer's inspector will check. Third, it puts the contractor on the hook in writing — the permit card names the license, the bond, and the scope.
When a contractor says 'I can save you $400 by skipping the permit,' they're describing a future problem they won't be around to solve. That $400 'savings' is a lien risk at title transfer, a potential insurance-claim denial, and an open correction order that any future permit pull will surface. We've pulled permits on remediation jobs for homeowners burned by no-permit installs. It is never cheaper in the end.
The permit process from start to inspection.
Six steps, every job, every jurisdiction. The timeline varies by building department — the sequence never does.
Permit timelines by jurisdiction.
Calendar days from application to permit issued, under normal conditions. Historic overlays, structural scope, and CDP requirements add time beyond these ranges.
- 1LADBS (City of Los Angeles) — 3–7 days standard, 14–21 days with structuralLADBS handles most window replacements through their online express portal. Standard retrofits with no structural scope clear in 3–7 calendar days. Header modifications, seismic anchor work flagged at plan check, or multi-unit residential jump to 14–21 days and go through the full plan check queue.
- 2Beverly Hills — 14–21 days, plus 10–14 days historic screening on pre-1965 homesBeverly Hills Building & Safety runs its own queue, slower than LADBS on standard permits. Pre-1965 homes trigger additional architectural screening — add 10–14 days and expect possible COA (Certificate of Appropriateness) requirement if the home is in a historic context area.
- 3Pasadena — 14–21 days, plus 30–60 days COA if in a landmark districtPasadena has one of the most active historic preservation programs in the county. Properties in a landmark district require a Certificate of Appropriateness from the Historic Preservation Commission before the building permit issues — 30–60 days, possibly with a public hearing. We identify landmark status on our pre-bid walk.
- 4Santa Monica — 14–18 days, coastal commission overlay on CDPsStandard window permits run 14–18 days. Properties in the coastal zone may require a Coastal Development Permit on top of the building permit — that review adds 30–45 days and involves the California Coastal Commission. We check coastal zone status on every Santa Monica job before filing.
- 5Burbank — 7–12 days, fastest in our service areaBurbank offers over-the-counter approval for standard window replacements with no structural scope — same-day or next-day if the application and window schedule are clean. Standard review runs 7–12 days. Burbank's pace is why our quotes there come in at the lower end of the jurisdiction range.
- 6Glendale — 10–14 daysGlendale Building & Safety runs a consistent 10–14 day timeline. No over-the-counter program for window permits, but the queue is predictable and plan check comments are typically minor if the CF1R is submitted correctly.
- 7Malibu — 21–35 days, CDP required for many propertiesMost Malibu properties require a Coastal Development Permit — the entire city sits within the coastal zone — adding CCC review on top of city planning review. Chapter 7A fire-hardened glass is often required in the wildland-urban interface areas that cover most of Malibu. Plan for 21–35 days minimum, longer if the CDP triggers a comment period.
- 8Hidden Hills — 14–21 days, plus HOA architectural reviewHidden Hills has its own building department and an active HOA Architectural Review Committee. Both the building permit and HOA ARC approval are required before installation begins. ARC review runs 7–14 days; we submit both applications simultaneously to minimize elapsed time.
What the CF1R and CF2R forms are.
Most homeowners have never heard of the CF1R or CF2R forms. They're buried in the permit file and most installers never explain them. They matter more than the permit card itself.
The CF1R is the Certificate of Compliance. Filed at permit application — before any work begins — it lists every window scheduled for installation: manufacturer, model, frame type, NFRC U-factor, SHGC, visible transmittance, and the climate-zone calculation confirming Title 24 compliance. The plan checker reviews the CF1R during plan check; windows that don't hit Title 24 minimums cause permit rejections.
The CF2R is the Installation Certificate. Filed after final inspection, it confirms the windows actually installed match the CF1R — same model, same NFRC ratings, same locations. A discrepancy is a code violation flagged at inspection. Together, CF1R and CF2R form the building department's permanent compliance record. They follow the property, not the owner — a future buyer's inspector or insurance adjuster can pull them. The record existing is what protects you.
What happens if you skip the permit.
- 1No Title 24 compliance recordWithout the CF1R and CF2R on file, there's no official record the windows meet California Energy Code. A HERS rater cannot sign off on the building. Some SCE and SoCalGas rebate programs require the permit and compliance forms before paying out — you can install code-compliant windows and still be ineligible.
- 2Flagged on future permit pullsAny future permit on the property — kitchen remodel, ADU, roof replacement — triggers a review of prior work. Unpermitted window installations become an open correction item. The building department can require bringing the work into compliance before the new permit issues. A $400 permit skip becomes a $2,000–$8,000 remediation problem when it surfaces years later.
- 3Potential title-transfer requirementMany LA jurisdictions flag unpermitted improvements during title transfer. A buyer's inspector or city pre-sale inspection program can surface the windows, requiring the seller to permit, inspect, and close the work before the sale closes — or cut the price to compensate. We have seen unpermitted window jobs kill transactions within days of closing.
- 4No inspection record means no liability protectionIf the windows fail — seal failure, flashing leak, frame failure — and the install was never inspected, there's no record a licensed contractor did the work to code. The installer's bond and license are meaningless without the permit tying them to the job. The homeowner bears full liability with no recourse.
- 5Potential insurance claim denialIf unpermitted window work is adjacent to a covered loss — water intrusion, wind damage, fire — the carrier's adjuster reviews permit history near the loss. Unpermitted work adjacent to the loss is grounds for partial or full claim denial. A $12,000 window job without a permit can jeopardize a $60,000 water-damage claim.

What to keep for your records.
Once the final inspection passes and the CF2R is filed, the permit record is closed. You should receive — or request — a copy of three documents: the signed permit card, the CF1R, and the CF2R. These three items are the core of your window replacement record and the documents that matter at sale, refinancing, or insurance review.
Store these with your other home improvement documents — the same file where you keep your roof warranty, HVAC service records, and title policy. They follow the property, not you personally, so if you ever sell, the new owner's agent or escrow officer may request them. Having them ready shortens the transaction.
We provide a digital copy of all permit documents in a homeowner packet sent within 48 hours of permit closure. If you used a different contractor and can't find your permit documents, search the LADBS permit database at ladbs.org using your address — every permitted window install since approximately 2010 should appear. Pasadena, Burbank, and Glendale have equivalent online portals. If records are missing, that's the conversation to have with whoever pulled the permit before assuming they're gone.
One more item worth keeping: the manufacturer warranty registration confirmation. We register every product in the homeowner's name within 48 hours of install and send confirmation. If you did not receive warranty registration confirmation from your installer within a week of install, it likely wasn't filed — call the manufacturer directly with your address and install date to file retroactively. Milgard and Anlin both allow retroactive registration within 30 days. Marvin allows up to 60 days.
