Acres are the land the fire burned in each county and community, and places where it burned less than an acre are not listed. Communities are cities, towns and the unincorporated places the Census Bureau names, so land outside any of them is counted only in its county.

Buildings damaged

  1. Destroyed Over 50% damaged 30
  2. Major damage 25 to 50% damaged 3
  3. Minor damage 10 to 25% damaged 2
  4. Affected Up to 10% damaged 3

Buildings CAL FIRE inspected after the fire, by how badly each was damaged. Inspectors record homes, businesses and outbuildings within 100 meters of the fire, and cannot always reach every one, so the counts can differ slightly from other reports.
