Defensible space and fire: your questions answered

What is defensible space?

It is the managed area around a building, split into zones. The University of Nevada, Reno Extension guide Living With Fire describes Zone 0 as 0 to 5 feet from the house and made ember-resistant, Zone 1 as 5 to 30 feet kept lean, clean and green, and Zone 2 as 30 to 100 feet with reduced fuel. The idea is a less connected fuel bed around the home. Read our guide on defensible space zones 0, 1 and 2.

Does Nevada law require 100 feet of defensible space?

Not as a single statewide distance. Nevada Revised Statutes 472.500 requires owners within the State Forester Firewarden's jurisdiction to remove a fire hazard when directed, but the statute does not give a distance. Local fire districts adopt their own wildland urban interface codes, so requirements depend on your address. Call your fire district to confirm. The zone distances above come from UNR Extension's guidance, not from a statute. See insurance and defensible space.

What does Battle Born Tree Service do for fire mitigation?

We assess the specific fire risks at your house and remove fire fuel from around the property. The goal is a defensible zone where shrubs, trees and debris are less connected. The work includes brush mowing, trimming, debris removal and assessing the health of your trees. Our two ISA Certified Arborists build the plan. We do not install fireproof materials, but the plan can point to what to ask a contractor about. See defensible space and fire mitigation.

What is the difference between mastication, brush mowing and hand clearing?

Mastication grinds brush and small trees in place with a machine, and we have a masticating head. Brush mowing cuts and mulches smaller growth across open ground. Hand clearing is done by a crew near structures, steep ground or anything a machine cannot reach. The right choice depends on the slope, the density and what is nearby. The arborist chooses at the visit. Our guide compares mastication, brush mowing and hand clearing.

Do all my trees have to come out?

No. Defensible space is about spacing and ladder fuels, not clearing every tree. Limbing up removes the lower branches that carry fire into the canopy, and thinning opens gaps between crowns. Some trees are removed, particularly dead or crowded ones. The arborist recommends what to keep, and the estimate is free. Read our guide on ladder fuels and limbing up. Cabling or pruning may suit a tree you want to keep.

Which plants near the house are the biggest concern?

Junipers and certain other high-hazard plants burn hot when they sit close to a building, and dead material under any plant adds fuel. The 0 to 5 foot zone matters most. The arborist looks at what is planted against the house, under eaves and along fences. Debris on roofs and in gutters is also part of the assessment. Read our guide on junipers and other high-hazard plants.

Are there free evaluations or chipping programs?

Some fire districts offer them. TRPA says the North Lake Tahoe Fire Protection District (Incline Village and Crystal Bay) and Tahoe Douglas Fire Protection District (the Nevada south shore) issue defensible-space tree permits with a free evaluation. Other districts run chipping programs. Programs change by year and location, so call your district to confirm. We list what we know in our guide to free evaluations and chipping programs.

Will defensible space help with home insurance?

Insurers increasingly ask about it, but each carrier has its own rules, and your insurer decides what it accepts. Ask yours what documentation it wants. A written estimate and a record of the work are useful to keep. We cannot promise a premium change or a policy outcome. Our guide, home insurance and defensible space, covers what carriers commonly ask. For storm claims, see the insurance claims page.

How much risk does my community face?

The US Forest Service publishes wildfire risk data, and the town pages on this site show it for each community. Many Northern Nevada communities rank well above the national middle for risk to homes. Use the numbers as context, since they describe a community and not your lot. The data pages list the figures and sources, and the town pages list nearby mapped fires. See wildfire risk by community and large wildfires since 1980.

Can you clear a larger lot or a vacant parcel?

Yes. Lot clearing, brush mowing, masticating and logging are all on our service list, and we own the equipment for them, including a brush mower, a masticating head and a Bobcat T870 track loader. Describe the acreage, the vegetation and the slope when you call. Builders and landowners often need clearing before a project. See lot clearing and builders and land owners.
