Window & Door Installation in Malibu

The Coastal Commission is the headline. Any work that changes a window size, a door opening, or the exterior envelope on a home seaward of PCH or anywhere in the Coastal Zone needs a Coastal Development Permit — and a CDP can stretch the timeline to 75 days or more. Like-for-like replacements in the existing rough opening usually qualify for a Section 30610(b) exemption, but the City of Malibu still requires the exemption to be documented with photos, a site plan, and a manufacturer cut sheet showing identical size and operation. We've pulled 52 permits in this city; we know which projects need a full CDP, which ride the exemption, and which planner at City Hall to call when something is sitting in queue.

Salt air is the second variable, and it's the one most contractors get wrong. Within a mile of PCH, raw steel rusts through fasteners in two seasons, and standard mill-finish aluminum chalks and pits inside five years. We default to marine-grade fiberglass — Marvin Ultimate Fiberglass or Andersen Renewal Fibrex — for the bulk of beachfront work, and anodized aluminum from Western Window Systems or Fleetwood when the architecture calls for a steel-look profile. Stainless 316 fasteners only. Powder-coat is not enough on its own; the substrate has to be right.

Third is fire. Most of the canyon and hillside parcels — Topanga, Malibu Park, the hills behind Point Dume, Las Flores Canyon — sit inside a Very High Fire Hazard Severity Zone, which means Chapter 7A applies. That's tempered glass on every exterior opening within 10 feet of grade, ember-resistant venting on operable units, and a 20-minute fire rating on certain assemblies depending on setback. After the January 2025 Palisades Fire and the lingering rebuilds from Woolsey in 2018, plan check pays close attention to 7A line-by-line. We bring the spec sheet to the inspector before they ask.

Point Dume (north of PCH between Westward Beach and Zumirez): Mix of original 1960s ranch, modernist glass houses, and recent contemporary builds. Bluff-side parcels are inside the Coastal Zone, hillside parcels above Birdview are in the Very High Fire Hazard Zone — many homes hit both jurisdictions. We default to Marvin Ultimate Fiberglass with tempered glass throughout, anodized aluminum for the steel-look modernist work.

Malibu Colony / Carbon Beach (gated beachfront, PCH to the sand): The most aggressive salt exposure on the coast. Almost everything here is seaward of PCH, so any envelope change is full CDP territory. Like-for-like replacement is the workhorse — Fleetwood and Western Window Systems for the contemporary builds, Marvin Ultimate Fiberglass for the renovated 1950s bungalows. Stainless 316 hardware, no exceptions.

Malibu Park (north of PCH around Trancas, Busch, Morning View): 1960s and '70s post-and-beam canyon homes, plus newer Mediterranean estates. Almost entirely inside the Very High Fire Hazard Zone — Chapter 7A applies on every project. Tempered glass, ember-resistant venting, rated assemblies on tight setbacks. Marvin Modern and Western Window Systems handle most of what we install here.

Las Flores Canyon / Big Rock (PCH around Las Flores Creek, up into the canyon): Hit hard by the January 2025 Palisades Fire and still finishing Woolsey rebuilds from 2018. Mix of canyon post-and-beam, Mediterranean rebuilds, and a few mid-century holdouts. Coastal Zone overlay on the lower parcels, 7A on the upper parcels, sometimes both. Marvin Ultimate Fiberglass is the default — fire-rated, marine-grade, and Title 24 compliant in zone 6 without an upcharge.

Malibu window replacement involves compliance requirements that exist nowhere else in our service area at the same concentration. The Coastal Development Permit process, Chapter 7A fire zone glazing requirements, and marine-grade hardware specifications all apply simultaneously on many Malibu properties — and the Coastal Commission staff are more active in Malibu than anywhere else in their jurisdiction.

Coastal Commission jurisdiction in Malibu covers all properties within the Coastal Zone, which for practical purposes means all of Malibu along the PCH corridor and up the canyons for varying distances. Like-for-like window replacements typically qualify for a Coastal Development Permit exemption, but any change to opening dimensions, exterior materials, or exterior finish requires a full CDP application. We handle the exemption determination or CDP coordination as part of the permit intake process and maintain an active working relationship with the Coastal Commission's Los Angeles district office.

Chapter 7A fire zone requirements apply to the wildland-urban interface areas of Malibu, which include most of the canyon properties and hillside homes away from PCH. For those properties, exterior glazing must be fire-resistive: tempered glass minimum, or dual-pane with a tempered outer lite for better performance. We specify fire-rated glazing as standard for all Malibu hillside projects and include the compliance documentation in the permit package.

Marine-grade 316 stainless hardware is standard on all Malibu projects — the salt air environment demands it. Frame materials for oceanfront and near-ocean properties should be aluminum-clad or thermally broken aluminum. Standard vinyl is acceptable in the canyon areas away from direct marine exposure.
