A community rebuilding after the Eaton Fire.
The January 2025 Eaton Fire moved through Altadena's foothill neighborhoods with a speed that left thousands of households facing a full rebuild at once. That scale creates real pressure on every homeowner's timeline: permitting queues, contractor availability, and material lead times all compound when an entire community is rebuilding in parallel. Panelized construction shortens the part of that timeline we can control, the time a home spends under construction once plans are approved. Altadena is one of several California locations where we offer dedicated rebuild programs.
Heavy equipment is not always required, but a reach forklift (telehandler) is our preferred method for handling and installation. We plan equipment and staging around each site, which matters in a neighborhood where multiple homes on the same block may be under construction simultaneously. Our four pillars of cost, carbon, complexity, and compliance guide every rebuild we coordinate.
Rebuilding with a fire-resistant frame, not just a fire-resistant finish.
When a home is lost to wildfire, the frame itself becomes part of the decision for what comes next. 4C SAFE™ is steel-framed and fire-resistant, carrying a 1-HR and 2-HR fire rating, code listed (patent pending). That code listing is applicable to all construction types, not just the more restrictive categories that limit some wood-framed alternatives. SAFE™ exterior walls are WUI-compliant, built for California’s wildfire construction requirements (formerly Chapter 7A, now the California Wildland-Urban Interface Code) that apply to rebuilds in Altadena’s fire hazard zones. For a part-by-part look at roofs, vents, windows, decks and framing, see our guide to fire-resistant house materials.
Our CEO talks about Altadena rebuilds and why fire-rated walls were part of the plan from the start in Why We Started 4C.
Fire-resistant from the frame out
Steel framing and fire-resistant construction give Altadena homeowners a rebuild that starts from a fundamentally different fire risk profile than the home it replaces.
Rebuild timelines that respect urgency
Pre-engineered, pre-labeled panels help reduce onsite construction time versus conventional framing, without skipping code-required detailing.
Fits the plans you already have
4C SAFE™ integrates with conventional design, financing, and permitting workflows, so a rebuild in progress doesn't need to start over architecturally. Compare it against our wood-framed 4C ECO™ system on our systems overview.

How 4C fits your Altadena rebuild.
Altadena rebuilds call for careful coordination of design, site requirements and construction logistics. 4C works with your project professionals to define the component scope and plan its manufacturing, delivery and installation.
The SAFE™ steel system offers ignition-resistant materials and code-listed exterior wall assemblies, including available 1-hour and 2-hour fire-rated options. Planning, permitting and inspections follow the traditional local process.

Adding an ADU while you rebuild.
An Altadena rebuild is often the only practical moment to add an accessory dwelling unit, since the site is already being re-permitted and re-built, so pairing a main residence with an ADU avoids a second disruptive construction phase later. The 4C SAFE™ system carries the same fire-resistant, 1-HR and 2-HR fire-rated construction across both the residence and ADU. Homeowners working through a similar rebuild in Pacific Palisades can review the same approach.
