Wildfire mitigation is complex and varies by region, property type, and risk factors. No single standard covers every scenario. Our goal is to provide homeowners and businesses in wildfire-prone areas with general guidelines that reflect both national standards and Colorado-specific considerations. The best resource is not this checklist, but to reach out to one of the many community-focused organizations available here: Get Accessed or to reach out to local wildfire authorities.

Our checklist is a compilation of best practices drawn from multiple trusted sources, including:

  • NFPA Firewise USA®

  • IBHS Wildfire Prepared Home Standards

  • Colorado State Forest Service (CSFS)

  • Colorado Division of Fire Prevention and Control (DFPC)

Please note, recommendations can change and we are not the authority on wildfire prevention and preparation. Always follow guidance from your local wildfire authorities, align with local regulations, and adopt science-based practices proven to reduce ignition risk.

Wildfire Prepare Checklist for Home Hardening and Defensible Space

A. Home Hardening (Building Envelope Upgrades)

Roof

  • Install/maintain a Class A fire-rated roof (metal, asphalt fiberglass shingles).
  • Regularly inspect and clear roof, eaves, and skylights of debris (needles, leaves).
  • Seal leading roof edges and intersections with non-combustible flashing.

Eaves, Soffits, and Vents

  • Box in eaves and enclose soffits with non-combustible material.
  • Install ember-resistant vents with metal screening (openings ≤ 1/8 inch).
  • Fit dryer and exhaust vents with a non-combustible louver or flap.

Gutters

  • Use non-combustible gutters (metal preferred); install metal drip edge to cover fascia.
  • Install a non-combustible gutter cover to limit debris accumulation.
  • Keep gutters clear of debris.

Siding & Wall Bases

  • Upgrade siding to ignition-resistant materials (fiber cement, stucco, metal).
  • Retrofit vulnerable areas with at least 6 inches of non-combustible material at base and roofline intersections.

Windows & Doors

  • Install double-paned, tempered glass windows.
  • Use ignition-resistant frames and shutters.
  • Install fire-rated exterior doors and mitigate the full assembly, including the door jamb, where embers collect.
  • Enclose the underside of bay windows with non-combustible material.
  • Ensure garage doors are properly sealed with weather stripping.

Decks & Fences

  • Choose a fully non-combustible deck assembly (joists, posts, railings, and walking surface) where possible; if using composite or ignition-resistant decking, ensure a solid walking surface with no gaps.
  • Keep the underdeck area clear of combustibles at any height; where the deck is low to the ground, enclose it with 1/8-inch or finer non-combustible mesh.
  • Remove all combustibles from on/under decks.
  • Use non-combustible fencing within 5 feet of the home.
  • Remove back-to-back (double) fence rows, which trap debris and create an ember bed.

Accessory Structures

  • Ensure sheds and other structures within 30 feet are mitigated or relocated.

C. Emergency Access & Preparedness

  • Ensure driveway has 24 feet horizontal and 13.5 feet vertical clearance for emergency vehicles.
  • Install address signs with 3-inch reflective lettering on non-combustible material, visible from the road.
  • Maintain multiple ingress/egress routes if possible; pre-identify rendezvous locations.

B. Defensible Space (Vegetation Management)

Zone 0 (0–5 ft: Immediate Ember-Resistant Zone)

  • Create a 5-foot non-combustible buffer around the home and attachments.
  • Use gravel, rock, or hardscape—no wood mulch or flammable plants.

Zone 1 (5–30 ft: Lean, Clean, Green Zone)

  • Remove surface fuels (needles, mulch, overgrown grass).
  • Mow grass to less than 6 inches.
  • Remove junipers, cedar hedges, and other volatile ornamentals.
  • Maintain proper crown spacing between trees/shrubs.
  • Prune trees and remove ladder fuels.

Zone 2 (30–100 ft: Reduced Fuel Zone)

  • Thin trees and shrubs for adequate crown spacing.
  • Prune trees and remove ladder fuels.
  • Maintain healthy forest ecosystem (consult specialists for forest health issues).

Combustible Storage

  • Store firewood, lumber, hay bales, and other combustibles at least 30 feet from the home.
  • Relocate propane tanks at least 30 feet from the home and mitigate surroundings.

Minimum Defensible Space

  • Maintain a minimum of 100 feet of defensible space where feasible; greater distances may be recommended depending on slope, vegetation, and topography.

D. General Wildfire Preparedness

  • Review insurance coverage for full replacement value to current code.
  • Complete a home/business inventory (photos, video) and store off-site.
  • Prepare an evacuation kit (“go bag”) and plan for pets/livestock.
  • Register for emergency notifications (e.g., Genasys, local alert systems).
  • Stay informed on fire restrictions and active wildfires (e.g., westslopefireinfo.com).
