Primary Parcel Hazard Mitigation

Fuel removal and displacement (when possible)
is always preferable to exterior hardening.

Assess property features that can contribute to fire pathways on or across a property to protect the home (Table C):

  • Firewood piles ($)
  • Vegetation ($ to $$)
  • Sheds ($ to $$$)
  • RVs ($)
  • Fences ($)


Additional mitigating actions and targeted hardening of the residential structure and nearby fuels may be necessary when a sufficient separation distance is not possible.

Scenario 1 - Exterior hardening of the primary residence is not necessary because the distance between the home and shed is sufficient to prevent ignition by flames. Ember protection is still needed, however.

Scenario 2 - For intermediate separation distances, directional hardening of the home facing the shed (indicated in blue) can help increase the ignition resistance of the residence.

Scenario 3 - The spacing between the home and shed is too close. The fire exposure to the home will likely be too intense for exterior hardening to be cost-effective. Removing the shed is best.
