In late January, the California Department of Forestry and Fire Protection estimated that more than were destroyed by Los Angeles wildfires. California leaders have implemented a $2.5 billion wildfire relief package as environmentalists, urban planners, and others are now debating how and where to rebuild communities in high-risk wildfire zones safely.

But wildfire concerns are not limited to southern California. In fall 2024, just a few months prior to the events in Los Angeles, , as blazes in New York and southern Massachusetts also sparked concerns. In fact, live in census tracts with a 鈥渧ery high鈥� wildfire risk, while nearly 15 million live in areas deemed 鈥渞elatively high.鈥�

In light of these events, Farzana Gandhi, M. Arch., associate professor of architecture, shares building strategies for fire-prone areas.

While there鈥檚 no such thing as a 鈥渇ire-proof鈥� building, certain design choices can help safeguard a home during a wildfire. Gandhi, a registered architect in New York and a LEED-accredited professional with expertise in sustainable design, urges builders to use fire-resistant materials, such as 鈥渟tucco rather than wood for the exterior finish, as well as metal gutters and double-paned tempered glass for windows,鈥� which can slow incoming heat. In addition, when building homes in fire-prone areas, recommend avoiding common residential design features, like overhanging roofs and eaves, which can create crevices for airborne embers.

She advises that homes in fire-prone areas be built with more than 20 feet between them, to help ensure that the heat from one structure does not reach surrounding homes. In wildfire scenarios, buildings tend to catch fire from the structures immediately nearby, including wood fences and plants. Dry, dead vegetation burns easily, increasing the probability of an intense and faster-spreading fire. While healthy plants may not burn as easily, ultimately, all vegetation can act as fuel. For this reason, fire-prone areas in California often have flammable vegetation standards, along with building codes, Gandhi notes.

鈥淭hese include creating a buffer zone of 鈥榙efensible space鈥� around homes by landscaping and clearing out flammable brush and vegetation on the ground and by cleaning gutters. Additionally, trees are required to be trimmed back from the roofline, and plants and bushes must be spaced out. Attic vents must also have a mesh covering their openings, which are limited in size,鈥� she says, acknowledging that these vents can be another trap for flying embers.

However, many existing, older structures do not currently meet the stringent building requirements for wildfire areas and will need to be retrofitted to be brought up to code.

鈥淏uilding to code doesn鈥檛 necessarily add to the cost, and there is no reason why such preventive measures should not be taken. But even fire-resistant materials have limits to the number of hours their resistance holds,鈥� says Gandhi.

In addition, at the neighborhood level, she calls on cities to invest in 鈥榮mart鈥� infrastructure systems that aid in early fire detection. These systems can provide real-time data on fire conditions, including temperature, smoke density, and the spread of flames, allowing firefighters to make informed decisions during an emergency.
