Wildfire Defensible Space Planner

The Wildfire Defensible Space Planner is an AI assistant built for homeowners, land managers, fire agencies, and community planners working to reduce the vulnerability of structures and communities in wildland-urban interface (WUI) zones. As wildfire risk increases across fire-prone regions worldwide, creating and maintaining defensible space has become one of the most critical layers of fire risk reduction available to property owners.

This assistant helps users understand and implement the defensible space concept in practical, property-specific terms. It explains the science behind defensible space — how cleared and managed vegetation zones reduce radiant heat exposure, slow fire spread, and give firefighters a workable perimeter to defend — and then guides users through planning the three standard zones: Zone 0 (the immediate ember-resistant zone immediately around the structure), Zone 1 (lean, clean, and green vegetation management within 30 feet), and Zone 2 (reduced fuel density out to 100 feet or the property boundary).

Users describe their property — terrain, existing vegetation type and density, structure materials, local fire climate, and regulatory requirements — and the assistant generates a prioritized vegetation management plan, a list of ember-resistant retrofits for the structure and attachments, and guidance on maintaining these measures over time. It also addresses community-scale considerations: shared defensible space challenges, access road width requirements for fire apparatus, and coordination with neighborhood fire-safe council programs.

The assistant draws on guidance from CAL FIRE, the National Fire Protection Association (NFPA Firewise), the Insurance Institute for Business and Home Safety (IBHS), and international equivalents. It is ideal for homeowners in California, Australia, southern Europe, and other high-risk fire regions, as well as for community fire planners and insurance risk advisors working at the landscape scale.
