Los Angeles fires: Mutual aid
Where and what to donate

Mutual aid
The Mutual Aid Los Angeles Network (MALAN) has a spreadsheet of Fire & Wind Storm Resources. It lists over 200 organizations in California, organized by the type of aid, with notes about which type of donations they're accepting and which they're providing.
Other organizations
Additional resources I've seen shared elsewhere that aren't on the spreadsheet:
Los Angeles Regional Food Bank
California Community Foundation
Emergency housing through Airbnb
Air quality: Masks needed
I've seen comments about air quality.
"The city of Rosemead is providing free N95s and KN95s to the public which can be picked up at the Rosemead Chamber of Commerce on Muscatel Ave." They're open today "8am-5pm, and 10am-2pm Saturday and Sunday." (Bluesky)
Koreatown for All is also accepting and distributing masks. They take donations by Venmo and PayPal.
