A year and a half after the Eaton Fire, Altadena’s rebuilding work has started, but the pace remains uneven. Los Angeles County reported 9,419 structures destroyed and another 1,076 damaged. As of June 2026, 26.7% of destroyed structures had rebuild permits, while less than 1% had finished construction.
That slow climb matters because wildfire risk does not stop at the tree line once flames reach a neighborhood. The Eaton and Palisades fires highlighted structure-to-structure fire spread, where burning buildings expose nearby homes to embers, radiant heat, and direct flame. In that environment, construction decisions made during recovery shape how a community performs during the next event.
For design builder Trinidad Campbell, the material choice turned personal while walking a burned Altadena street with homeowner Margot Stueber. Campbell kept noticing what stood after the fire: masonry walls, chimneys, and concrete elements. She recalled telling Stueber, “The only thing left standing is block. We’re building with block.”
Stueber’s property became a benchmark for early recovery. It was the first in the community to complete Phase 2 debris removal through the U.S. Army Corps of Engineers. It also became the first residential property in the burn area to break ground, drawing visits from Gov. Gavin Newsom and Los Angeles County Supervisor Kathryn Barger.
Campbell finished drawings in roughly three weeks and pushed plans through quickly, but CMU did not bypass the permitting challenges that many rebuilds face. Construction began in late April 2025, and Stueber moved into the new home in February 2026.
The rebuild used CMU for a noncombustible structural system, with stucco finishing the exterior walls and drywall on the interior. The design drew on Bauhaus influences, and the property included an accessory dwelling unit built with CMU as well. After moving in, Stueber reported interior temperatures holding near 74 degrees on days in the 80s, then dropping to about 70 or 71 overnight, with limited air conditioning and minimal heating. Concrete masonry’s thermal mass absorbs and stores heat, slowing temperature swings as outdoor conditions change.
For mason contractors working in wildfire-prone regions, the Altadena rebuild puts a familiar system back in the conversation. Wall assemblies matter, but the article also underscores that roofs, openings, site conditions, and neighboring buildings stay critical parts of a fire-resilient plan.
The article also points architects and project teams to the Beauty of Block Design Collective, a fully funded resource connected to the Concrete Masonry Checkoff that offers technical guidance and design assistance for evaluating concrete masonry systems early in design.
