“DANGER: Lead Work Area” reads a sign on a front door of an Altadena home. “May damage fertility or the unborn child. Causes damage to the central nervous system.”

Block after block there are reminders that contaminants still linger.

House cleaners, hazardous waste workers and homeowners alike come and go wearing masks, respirators, gloves and hazmat suits as they wipe, vacuum and power-wash homes that weren’t burnt to ash.

It’s been a year of heartbreak and worry since the most destructive wildfires in the Los Angeles area’s history scorched neighborhoods and displaced tens of thousands of people. Two wind-whipped blazes that ignited on Jan. 7, 2025, killed at least 31 people and destroyed nearly 17,000 structures, including homes, schools, businesses and places of worship. Rebuilding will take years.

Some homeowners in areas of California with high wildfire risk could eventually get money for new roofs or to build fire-resistant zones around their properties under a new state law that went into effect Friday.

The Safe Homes grant program is designed to help low- and middle-income homeowners with fire mitigation. People who qualify could use grants to create 5-foot ember-resistant zones around properties, also known as Zone Zero, as required by law in some areas. The program will also contribute toward costs for fire-safe roofs.

As flames incinerated whole blocks in Southern California, fierce winds pushed dark, speckled ash through Rossana Valverde’s door frames, windows and vents. Her home stood a short drive from the worst destruction caused by January’s Eaton Fire, but she had gotten lucky: Apart from a singed tree, her property appeared unscathed.

Yet the acrid stench in the bungalow she shared with her husband suggested otherwise. The remains of other people’s homes now permeated hers.
