Why Fire Damage Is Often Hidden
Wood framing loses strength before it chars through. Steel connectors and hardware can lose temper at high temperatures. Concrete and masonry can spall or crack from rapid heating and cooling, especially when hit by water during firefighting. Smoke and soot also corrode metal over time. A structure that passed a visual walk-through may still have members that no longer carry their design load.
Warning Signs To Watch For
- Sagging rooflines, ceilings, or floors
- Doors and windows that no longer open or close squarely
- New cracks in foundations, slabs, stucco, or drywall
- Charring deeper than about 1/4 inch on joists, rafters, or studs
- Discolored or deformed steel beams, straps, or hold-downs
- Standing water, swollen subfloor, or soft spots underfoot
Steps To Take Before Repairs Begin
- Stay out until cleared. Wait for the fire department or building official to say the structure is safe to enter.
- Document everything. Photograph each room, the exterior, and the roof before any cleanup. Your insurer and your engineer both need this record.
- Contact your insurer. Most policies require prompt notice and will assign an adjuster. Ask whether a structural evaluation is covered; it usually is.
- Get a structural assessment. A licensed engineer identifies which members can stay, which must be replaced, and whether the foundation can be reused. This report becomes the basis for a repair scope and permit set.
- Secure the property. Tarping the roof, shoring damaged areas, and shutting off utilities prevents further damage while decisions are made.
Repair Or Rebuild?
When damage is limited to one area, a repair with engineered details is often the quickest path. When framing is compromised across the house, or the foundation is cracked or heaved, a rebuild on the existing footprint can be more predictable in cost and schedule. After wildfire events, many California jurisdictions offer expedited like-for-like rebuild permits. A current survey, soils letter, and a complete plan set are what move those applications forward.
What A Plan Set Needs To Include
Jurisdictions typically ask for architectural plans, structural calculations, a foundation plan, Title 24 energy compliance, and, in a wildfire zone, Chapter 7A ignition-resistant construction details. Preparing these together, under one roof, avoids the back-and-forth that delays plan check.
Pasquini Engineering, Inc. has prepared rebuild plan sets for homeowners in Altadena, Pacific Palisades, Paradise, and Santa Rosa. If you are unsure whether your home can be repaired, a structural assessment is the right first call.
