Defensible Space Laws & Compliance

Written By Ijaz Ali

Wildfires are a constant threat in California, and state law requires property owners to take proactive steps to protect their homes and land. The key regulation is Public Resources Code (PRC) § 4291, which mandates 100 feet of defensible space around structures. Recent updates add Zone 0, an ember-resistant zone within five feet of buildings, where most wildfire ignitions begin.

At Inertia Land Management, we help property owners achieve defensible space compliance in California, keeping properties safe, insurable, and wildfire-ready.

What Is Defensible Space?

Defensible space is a buffer zone between your home and surrounding vegetation that slows fire spread and provides firefighters with safer working conditions. California’s PRC § 4291 breaks it down into three zones:

  • Zone 0 (0–5 feet): Keep this ember-resistant area free of wood mulch, firewood, and flammable plants. Use gravel, pavers, or stone.

  • Zone 1 (5–30 feet): Remove dead vegetation, trim trees, clean gutters, and space plants to reduce fuel.

  • Zone 2 (30–100 feet): Mow grass low, thin shrubs, and create vertical spacing between trees and vegetation.

Why Compliance Matters

Staying compliant with California defensible space laws protects more than just your property:

  • Safety: Reduces the chance of wildfire ignition.

  • Insurance: Helps meet coverage requirements.

  • Community Protection: Lowers overall wildfire risk in your area.

Failure to comply can lead to citations, fines, or loss of insurance coverage—and far greater risks during fire season.
