Flood Insurance May Make You Wait 30 Days

The storm on the map will not speed up a policy waiting period. Check the home's flood exposure and coverage now, because standard homeowners insurance usually leaves this water damage outside.

A forecast is not the time to discover that a flood policy has a waiting period. Flooding can occur outside the highest-risk mapped zones, while a standard homeowners or renters policy generally treats flood as a separate hazard.

Check more than the map color

Review the current FEMA map, elevation, drainage, nearby water, past events, local stormwater systems and seller disclosures. Ask the insurer which building and contents losses are covered and what exclusions or limits apply.

Understand the waiting-period exceptions

FloodSmart lists exceptions connected to making or changing certain mortgage loans, policy renewals, newly designated high-risk zones and some floods made worse by wildfire on federal land. Confirm the exact effective date in writing.

Reduce the damage potential

Elevating utilities, moving valuables, adding flood openings where appropriate, improving drainage and protecting documents may reduce losses. Structural changes and floodproofing should follow local code and qualified design.

The HomeCostGrid view

Price flood coverage while comparing homes, not after closing. Put the premium, deductible, uncovered contents, temporary housing and a mitigation allowance into the ownership scenario.
