Ocean-facing, salt-air rated, Chapter 7A compliant. The right aluminum track system for coastal Malibu exposure. Coastal Commission permit handled. Quote in 48 hours.
Sliding glass doors in Malibu are subject to more regulatory and environmental requirements than anywhere else we install. Chapter 7A (Very High Fire Hazard Severity Zone) requires dual-pane tempered or laminated glass and aluminum or fiberglass frames on rated elevations — vinyl sliding door frames are not compliant on ocean-facing or hillside-facing elevations in most of Malibu. The Coastal Commission's jurisdiction means any change to the opening size requires a CDP; like-for-like slides can often get a categorical exemption, but it must be documented. And salt-air corrosion means marine-grade aluminum track and stainless hardware are not options — they're requirements for a 20-year lifespan at the coast.
Fleetwood aluminum or Western Window Systems Series 600 with marine-grade powder coat and stainless track hardware. Dual-pane tempered Low-E for Chapter 7A compliance. We do not install vinyl sliding doors in Malibu's coastal zone.
Malibu sliding door replacements are subject to Coastal Commission oversight when the structure is within the Coastal Zone boundary — roughly the first half-mile from the water. We handle the exemption determination letter as part of our permit intake; most like-for-like replacements qualify for an exemption but require documentation. Corrosion is the defining material constraint: hardware must be 316 marine-grade stainless at minimum, and we typically up-spec to Andersen or Marvin coastal packages with multi-point locking and silicone-sealed frames.
