Defensible Space Scorecard

Rate Your Property’s Zone 0-2 Compliance

A defensible space scorecard walks your own property through the same three zones a CAL FIRE or local fire department inspector checks, one zone at a time, before anyone official shows up to look. Score yourself honestly on what sits within five feet of your house, what’s growing between five and thirty feet out, and what’s happening from there to your property line or the hundred-foot mark, and you’ll know exactly where a real inspection is likely to flag something.

This page explains what the scorecard checks and why, how the scoring works, and what to do once you have a number. If you want to start with your property’s fire hazard severity zone designation first, our fire hazard zone lookup tool checks that by address. Read on for what a low score in any one zone actually means and when it’s worth calling in a professional.

What a Defensible Space Assessment Actually Covers

A defensible space assessment isn’t a single yes-or-no question. It’s a walkthrough of the full hundred-foot buffer required under California’s Public Resources Code Section 4291 for properties inside a State Responsibility Area or a Very High Fire Hazard Severity Zone, broken into the three zones CAL FIRE and local fire agencies actually inspect against. An assessor, or a homeowner using this scorecard, checks combustible material against the house, plant spacing and dead growth in the middle distance, and fuel thinning out toward the property line. Each zone carries its own standard, so a property can pass comfortably in one zone and fail in another.

Zone 0, Zone 1, and Zone 2: What the Scorecard Rates

Zone 0 covers the five feet immediately around the house, including attached decks and stairs, and it carries the strictest standard of the three. The scorecard checks for wood mulch, stored firewood, propane tanks, combustible plants pressed against the siding, and any wood fence or gate butted directly against the structure. This is the zone most tied to the newer Zone Zero standard under AB 3074, and it’s where most points on a low-scoring property tend to disappear.

Zone 1 runs from five to thirty feet out, and the standard shifts from eliminating combustible material to breaking up what would otherwise let fire climb or spread. The scorecard rates canopy spacing between trees and shrubs, dead branches and dry leaf litter, mowed grass height, and how far tree limbs have been trimmed up from the ground, since low limbs are the ladder fuels that let a ground fire reach the canopy.

Zone 2 extends from thirty feet to the full hundred-foot boundary, or to your property line if it’s closer, and the scorecard shifts again toward thinning rather than clearing. Healthy, well-spaced vegetation can stay in place. Points come off for dead and downed material left in place and for vegetation dense enough that fire could move continuously from the ground into the canopy.

How Scoring Works: Critical Items vs. Nice-to-Have

Not every item on the scorecard carries the same weight, and treating all of them as equal is how homeowners talk themselves into a false sense of security. Combustible material inside Zone 0, a wood fence against the house, firewood stacked at the wall, mulch pressed into the siding, is scored as critical, because it addresses the exact mechanism, an ember landing on or against a structure, behind most home losses in a wildfire. A single critical failure in Zone 0 should pull your overall score down more than several minor items in Zone 2.

Zone 1 and Zone 2 items split between meaningful and nice-to-have. Ladder fuels and continuous canopy contact are scored close to critical, since they’re what let a ground fire become a structure fire. Grass height a few inches taller than ideal, or a handful of dead leaves that haven’t been raked yet, matter less and shouldn’t sink an otherwise solid score.

What to Do With Your Score

A high score across all three zones means your property is in good shape and ready for a real inspection whenever one is scheduled. Keep dated photos of each zone as your baseline, since conditions change every fire season and a photo record makes next year’s check faster.

A low score in Zone 0 is the one that deserves the fastest attention, since it’s both the strictest standard and the smallest, most affordable zone to fix. Clearing five feet of combustible material around a house is a weekend project for most homeowners, not a major renovation. A low Zone 1 or Zone 2 score usually points to ongoing maintenance, canopy spacing, dead-material removal, rather than a single fix, and can reasonably be worked through over a longer timeline.

When a DIY Scorecard Is Enough, and When to Call a Professional Inspector

This scorecard is built to match the same standard a CAL FIRE or local fire department inspector uses, but it isn’t a substitute for one. Use it as a first pass: catch the obvious Zone 0 problems, get a general read on Zone 1 and Zone 2, and fix what you can before anyone official is scheduled to look.

Call a professional inspector, or a fire-safe fencing contractor with real Zone Zero experience, when your score comes back low across more than one zone, when you’re not confident judging plant spacing or ladder fuels on a sloped or heavily wooded lot, or when you’re facing a compliance deadline tied to an insurance renewal. A trained eye catches details a homeowner walkthrough tends to miss, like which species on a property actually count as combustible under the local standard.

Turning Your Score Into Insurance Documentation

A completed scorecard, paired with dated photos, is exactly the kind of record insurers ask for when they’re weighing a policy renewal in a high fire hazard severity zone. It won’t guarantee a discount on its own, but it gives you something concrete to bring to that conversation instead of a verbal assurance that the yard looks fine.
