On the morning of Nov. 9, Phillip Vogt got a phone call. The person on the other end said he wouldn’t be able to make their appointment at Mr. Vogt’s home because the roads leading there were blocked by California Highway Patrol. It was then that Mr. Vogt looked out his window: The hillsides surrounding his home had been consumed by a wildfire moving at breakneck speed.
It took Mr. Vogt 15 minutes to pack a few belongings into his white Prius, but by then it was too late. Nearby homes were ablaze. “There was no way of escaping,” he said. For a time he used a hose to extinguish the burning embers raining down, but he was eventually overtaken by flames that disintegrated a section of the hose and burned his hand, arm and eyes.
Mr. Vogt retreated to his house, surrounded by what would later be named the Woolsey Fire, one of the worst wildfires ever to break out in California. He lost cell service; his wife, who was at her parents, had a “complete breakdown.”
“I relived our wedding on the property, the good times, the tough times, what he was going through and what I would find after returning,” she said.
The next day, Mr. Vogt emerged with minor burns. His house—the only home in the Malibu neighborhood left standing—sustained a little smoke damage. In addition to amenities like an ocean view and wine library, the five-bedroom, Spanish-style house was built with every feasible fire-safe feature Mr. Vogt could think of, including concrete-and-steel walls, rooftop ember guards and heat-resistant windows. The hose he had used in the fire is 1,000 feet long, supplied by tanks holding 50,000 gallons of water.
“It’s your home,” said Mr. Vogt, a 43-year-old commercial design and construction manager. “You don’t want to leave anything to chance.”
Mr. Vogt stands at the vanguard of a movement toward making homes more fire safe in the West’s increasingly combustible wild lands. A triple whammy of rising temperatures, overgrown forests and rampant development in wooded areas has created what local officials call an unprecedented fire threat to communities. Last November, the Woolsey Fire combined with the Camp Fire in the northern part of the state destroyed about 20,000 homes and other structures at a cost of between $15 billion to $19 billion, according to data providerCoreLogic .
The dramatic increase in big fires—15 of the 20 most destructive on record in California have occurred since 2000—has prompted calls by state and federal officials to increase thinning of forest areas. It has also triggered action to address another factor behind the growing property damage: the vulnerability of homes themselves, such as by being situated too close to vegetation and by being constructed from too many flammable materials like wood.
Over the past 20 years, communities and counties have adopted voluntary building guidelines for new homes to make them more fire resistant, while they have been mandated in certain other places like Deschutes County, Ore. and statewide in Washington and California. Among other things, the California building measures adopted in 2007 require new homes in high-fire areas to be equipped with guards or other protection over rooftop openings to resist blowing embers—one of the biggest threats to structures in a wildfire.
Some places go beyond those requirements. In north San Diego County, the Rancho Santa Fe Fire Protection District has adopted requirements above the state fire code that includes more fire-resistant landscaping and construction materials. The district conducts weed-abatement inspections to make sure vegetation is trimmed back from structures and roadways, said Marlene Donner, fire marshal in a district of 33,000 people. The district, like many others, pushes for no vegetation within 5 feet of a home and 50 feet to 100 feet of so-called “defensible” space around it.
The measures paid off: A 2014 wildfire swept through and threatened 50 homes, but none was lost, she said.
The most important part of fireproofing is the home itself. “The home is the target—you do not want your house to catch on fire,” said Marti Witter, a fire ecologist with the Santa Monica Mountains National Recreation Area, which abuts Mr. Vogt’s property.
Mr. Vogt’s two-story home is in a rural section of Malibu, near where his wife works and where his two children go to school. Among other reasons he and his wife fell in love with the property was its seclusion and vantage point overlooking the Pacific. In his research before buying the property, Mr. Vogt learned that it was in one of the most fire-prone areas of Southern California—atop a ridge in mountains choked with flammable chaparral.
