Where the damage is

Acres tell you how much land burned. Most of it is brush and forest. Repair and rebuild work follows the buildings in a fire's path. CAL FIRE inspectors count those building by building.

Observed

Los Angeles County had 87% of the structures destroyed or damaged in 2015–2025 but 32% of the acres burned. Riverside and San Bernardino had 35% of the acres and 2% of the damaged structures.

  • Share of acres burned
  • Share of structures destroyed or damaged
Structures are those CAL FIRE inspected (DINS). Fires it did not inspect are missing, so a county's damage can be undercounted.

Structures inspected by CAL FIRE, by fire year

  • Destroyed (over 50% damaged)
  • Damaged, still standing

No CAL FIRE inspection records here for 2015, 2016. That means no inspection was filed, not that nothing burned.

"Damaged" = major (25–50%), minor (10–25%) or affected (up to 10%). The newest record is from Jan 6, 2026, so 2026 fires are not in yet.

What this does and doesn't tell you

It tells you where fires of 10 acres or more burned since 2015, how many acres, and how many buildings CAL FIRE inspectors found damaged or destroyed.

  • It does not count jobs. It does not show how many homes need cleanup, repair or a rebuild, or who does the work.
  • Smoke and ash damage outside the fire line is not here. Inspectors work inside and near the perimeter. Homes with smoke damage farther away do not show up.
  • Not every fire gets an inspection. Fires CAL FIRE did not inspect are missing from the damage counts. The newest inspection record is from Jan 6, 2026, so 2026 damage is not in yet.
  • Acres are mostly wildland. A big fire in the mountains or desert can burn many acres and few buildings. A small fire in a town can do the opposite.
  • 2026 fire shapes are preliminary. The "same date" comparison uses fires that started by Sep 19 each year.
  • Fires under 10 acres are left out. They are many, but burn few acres.

CAL FIRE FRAP, California Fire Perimeters (interagency: CAL FIRE, USFS, BLM, NPS, FWS) (Fire years 2015-2025); NIFC WFIGS Interagency Perimeters (year to date) (Fires discovered in 2026; perimeters are preliminary and change while fires burn); U.S. Census Bureau TIGERweb county boundaries

Notes (5)
  • Fires of 10 acres or more that burned in a Southern California county. A fire that crossed a county line is counted in each county for the acres that burned there.
  • 2015-2025 perimeters come from CAL FIRE's historic fire perimeter database; 2026 fires come from the national (NIFC) year-to-date perimeters, which are preliminary until CAL FIRE publishes the year.
  • Start dates are the local discovery date where the fire can be matched to the national incident record; otherwise CAL FIRE's alarm date, which can read one day late for evening starts.
  • Perimeters show where fire burned, not damage; most of the acreage is wildland.
  • Map outlines are simplified for display.
Structures damaged by wildfire in Southern California (CAL FIRE DINS) Observed

Covers through Jan 6, 2026. Retrieved .

Notes (6)
  • Counts are structures inspected by CAL FIRE damage inspection teams after each fire, by damage level, building type and year built. A structure is a building, not a home: an apartment building is one structure.
  • Not every fire is inspected, and some fires on local or federal land are missing. Records start in 2013.
  • Before 2018 inspectors recorded only damaged and destroyed structures; since 2018 they also record undamaged ones, so 'no damage' counts are not comparable across that break.
  • Single-family includes mobile homes. Commercial includes mixed commercial/residential buildings. Other means sheds, garages, barns and infrastructure.
  • Year built comes from county assessor records. It is a fact about the building, not evidence of any material inside it.
  • CAL FIRE last updated this data on 2026-01-06; 'as of' is that date.
