What This Means for Home Insurance in Portland

Flood Insurance

Standard homeowners policies do not cover flood damage. Properties in FEMA flood zones may be required to purchase separate NFIP coverage. Flood insurance is strongly recommended in this area.

Earthquake Insurance

Earthquake damage is excluded from standard homeowners policies. A separate earthquake rider or policy is required. Given the elevated earthquake risk, this coverage is worth considering.

Wildfire & Wind

Homeowners insurance typically covers wind and fire damage, but high-risk areas may see coverage restrictions or higher premiums.
