Home hardening reduces the likelihood that a structure will ignite during a wildfire, particularly from embers, radiant heat, and direct flame contact. These measures complement defensible space and evacuation planning.

How Homes Ignite in Wildfires

Embers

Wind-driven embers enter vents, eaves, or gaps and ignite materials inside or on the structure

Radiant heat

Heat from nearby burning vegetation or structures breaks windows or ignites siding

Direct flame contact

Fire reaches the structure due to insufficient clearance or combustible attachments

Priority Home Hardening Actions

Roof

  • Install or maintain a Class A fire-rated roof.
  • Keep the roof free of leaves and debris.
  • Cover gaps at roof edges and ridgelines.

  • Use ember-resistant vents (1/8-inch corrosion-resistant metal mesh or approved designs).
  • Screen attic, crawl space, and foundation vents.
  • Seal gaps around utility penetrations.

  • Enclose open eaves.
  • Repair damaged fascia and soffits.
  • Use non-combustible or ignition-resistant materials.

  • Install dual-pane tempered glass windows.
  • Use tight-fitting doors with non-combustible frames.
  • Add metal screens to windows where appropriate.

  • Use ignition-resistant or non-combustible siding.
  • Repair cracks, gaps, and warped materials.
  • Maintain clearance between siding and ground.

  • Use ignition-resistant decking materials.
  • Remove combustible materials from under decks.
  • Break fence connections with a non-combustible section where they meet the home.

Defensible Space Reminder

Home hardening works best when paired with defensible space:

Zone 0 (0–5 feet)

Non-combustible zone

Zone 1 (5–30 feet)

Reduced fuel, well-spaced plants

Zone 2 (30–100 feet)

Thinning and maintenance

Zone 0 (0–5 feet)

Non-combustible zone

Zone 1 (5–30 feet)

Reduced fuel, well-spaced plants

Zone 2 (30–100 feet)

Permits and Building Requirements

Some upgrades may require permits or inspections.

Residents should consult the City’s Building Division before starting work.

Financial Assistance and Incentives

State and regional programs may offer grants or rebates for eligible hardening improvements.

Availability varies by year and funding source.

When and if such resources are made available, the City will advertise them on this page, along with its other communication platforms, including Facebook, X, and Instagram.
