Steel frame. Non-combustible. Chapter 7A compliant. Rebuilt to outlast the next fire, not just survive the last one.
The 2025 LA fires made one thing clear: wood-frame rebuilds in WUI zones are no longer the rational default. Steel frame is. We are the contractor that does it end-to-end.
In-house structural engineering for the rebuild, designed to California Building Code and Chapter 7A from the first sketch. Not retrofitted, not value-engineered down to wood at bid time.
Light gauge steel sourced and prefabricated to the drawings we engineered. Galvanized, dimensionally stable, dimensionally accurate to 1/256". No on-site improvisation.
Our trained crew erects the steel frame, then carries the project through MEP, drywall, finishes, and final inspection. One contract through to certificate of occupancy.
One contract. One contractor. Built for the long view.
Chapter 7A of the California Building Code governs construction in Wildland-Urban Interface (WUI) fire hazard zones. It is the single most important regulatory chapter for any home being rebuilt after a wildfire in Pacific Palisades, Malibu, Altadena, hillside Bel Air, Brentwood, Topanga, Mandeville Canyon, or any portion of LA, Ventura, or Orange County mapped as a Very High Fire Hazard Severity Zone (VHFHSZ).
Chapter 7A is not a recommendation. It is a code requirement, and it touches every part of the building envelope. The big-ticket items it regulates:
A wood-frame home rebuilt in a Chapter 7A zone can satisfy the code, but it does so by wrapping a combustible structural core in non-combustible cladding. Steel frame satisfies Chapter 7A at the structural core itself. The non-combustible classification carries from foundation to ridge, not just at the skin.
Why does that matter? Because the fire data from the 2025 Palisades and Eaton fires, like the data from Camp (2018), Tubbs (2017), and Thomas (2017) before it, shows that wildfire-driven structure loss is overwhelmingly ember-intrusion driven, not flame-front driven. Embers travel ahead of the fire, lodge in eaves, vents, decks, and roof valleys, and ignite the structure from a position the flame front never reaches. A non-combustible structural system gives those embers nothing to ignite, even if the cladding is compromised.
Rebuilding after a wildfire is the most consequential construction project a family will ever undertake. The structure, the documentation, and the insurance file all have to be right the first time. ESRL builds to that standard.
Light gauge cold-formed steel doesn't ignite, doesn't contribute fuel, doesn't transfer fire through the structural envelope. The core of the home is non-combustible from foundation to ridge.
Every assembly, Class A roof, ember-resistant vents, ignition-resistant siding, non-combustible eaves, dual-glazed tempered glass, decking, documented and submitted with the permit set. No retroactive compliance scrambles.
Material certifications, structural specifications, and Chapter 7A assembly schedules packaged for the insurance carrier or FAIR Plan underwriter. Non-combustible classification can reduce homeowner insurance premiums by up to 50% in fire zones.
Engineering, steel supply, installation, MEP coordination, finishes, certificate of occupancy. One contractor accountable for the whole rebuild, not three vendors pointing at each other when something goes wrong.
22 years of California residential construction experience, including in WUI fire zones across Los Angeles County, Orange County, and the LA hillsides. Familiar with LADBS, LA County Building & Safety, City of Malibu, City of Pasadena, and surrounding AHJs.
50-year structural warranty on the steel frame. Termite-proof, mold-proof, dimensionally stable for the life of the home. The rebuild is built to outlast the next fire cycle, not just survive the last one.
ESRL builds steel frame wildfire rebuilds across Los Angeles and Orange County, with concentrated experience in the WUI zones most affected by the 2025, 2018, and 2017 fire seasons. Service area below.
Hardest hit by the January 2025 Palisades Fire. Effectively the entire community sits within Very High Fire Hazard Severity Zone. Chapter 7A applies to every rebuild. Pacific Palisades page →
Repeat-exposure city, Woolsey (2018), Franklin (2024), Palisades (2025). VHFHSZ across most parcels. Ocean corrosion adds a second durability driver for steel. Malibu page →
The Eaton Fire (January 2025) destroyed substantial portions of Altadena. LA County Building & Safety is the AHJ. Chapter 7A applies across the foothills.
Hillside Bel Air, Mandeville Canyon, and upper Brentwood are mapped VHFHSZ. Skirball Fire (2017) territory. LADBS jurisdiction with stringent slope and WUI requirements.
Topanga Canyon and Calabasas hillsides are deep WUI. LA County jurisdiction. Steel frame is the rational structural answer for these slope-and-canopy parcels.
Pasadena, La Cañada Flintridge, Sierra Madre, Glendale foothills. Eaton Fire exposure zone and historic Station Fire (2009) terrain. Each city has its own AHJ.
A wildfire rebuild is two projects running in parallel: the construction project and the insurance project. ESRL handles the construction-side documentation, the AHJ coordination, and the technical material that the insurance carrier or public adjuster needs to advance the claim. We don't replace your insurance attorney or public adjuster, we make sure the construction side never holds the claim up.
If you are early in the rebuild process, before architect selection, before insurance estimate finalization, ESRL provides a free pre-construction consultation that lays out the realistic schedule, code path, and documentation requirements specific to your parcel and AHJ. Begin a project →
Chapter 7A of the California Building Code governs construction in Wildland-Urban Interface (WUI) fire hazard zones. It requires non-combustible or ignition-resistant materials at the roof, exterior walls, decks, eaves, vents, and windows. If your home is in a Very High Fire Hazard Severity Zone, as is most of Pacific Palisades, Malibu, Altadena, and large portions of LA hillsides, Chapter 7A is not optional. Every component of your rebuild must comply. Light gauge steel frame structures satisfy Chapter 7A at the structural level by default, because steel is non-combustible.
Increasingly, yes. Following the January 2025 Palisades and Eaton fires, most California carriers, including admitted carriers and the FAIR Plan, are tightening underwriting for properties in WUI zones. Non-combustible structural classification is now either required, heavily preferred, or rewarded with significantly lower premiums. Steel frame qualifies for non-combustible classification and can reduce homeowner insurance premiums by up to 50% in fire zones. ESRL provides the documentation insurance underwriters request: structural specifications, Chapter 7A compliance package, and material certifications.
From signed contract to certificate of occupancy, a typical full custom rebuild of a 3,000 to 5,000 SF home in Pacific Palisades, Malibu, or Altadena takes 18 to 30 months. Roughly 4 to 8 months for design and permits, 12 to 22 months for construction. Steel frame compresses the framing phase significantly, the frame itself goes up in days rather than weeks. The variables that drive schedule are site access, lot clearing, hillside grading, soil remediation, and jurisdiction permit pace, not the structural system.
Yes. ESRL handles the construction-side documentation insurance carriers and AHJs require: structural drawings, Chapter 7A compliance package, Title 24 energy compliance, defensible space coordination with the landscape consultant, and submittal coordination with LADBS, LA County Building & Safety, City of Malibu, City of Pasadena, and other AHJs. We don't replace your public adjuster or insurance attorney, but we provide every document the construction side of the claim needs.
Three reasons. First, it is non-combustible by definition, it doesn't ignite, doesn't contribute fuel, doesn't transfer fire across the structure. Second, it integrates cleanly with the other Chapter 7A ember-resistant assemblies, ignition-resistant siding, Class A roofing, ember-resistant vents, dual-glazed tempered windows, you get a coherent non-combustible envelope from foundation to ridge. Third, steel frame is dimensionally stable, mold and termite proof, and carries a 50-year structural warranty, which matters for any home you intend to live in for the long term, especially one you have already lost once.
