Wildfire Season: Defensible Space Around Your Property

Creating defensible space—managed vegetation and clear zones around structures—is one of the most effective ways to reduce wildfire risk. Many Western states, including Colorado, encourage or require zones that slow fire spread and protect homes.

Zone 1: Immediate Home Ignition Zone

Within about 5 feet of the structure, use non-combustible materials for mulch, decks, and storage. Remove dry leaves, pine needles, and firewood from this area. Keep gutters and roofs clear of debris that could catch embers.

Zone 2: Fuel Reduction

Thin trees and shrubs so crowns don't touch. Remove ladder fuels—low vegetation that allows ground fire to reach tree canopies. Maintain spacing between plants and between groups of plants according to local fire authority or Firewise guidance.

Construction and Vents

Embers often enter through attic vents, open windows, and cracks. Use ember-resistant venting where recommended, and seal gaps in siding and roof edges. Class A roofing and fire-resistant siding add another layer of protection.

Maintenance

Defensible space is not a one-time project. Prune annually, clear dead vegetation, and reassess after wind events. Document your efforts for insurance and local inspection requirements.
