    Flood Insurance (Commercial)

    Flood is excluded from virtually every standard commercial and homeowners property policy in the United States. If your building floods and you don't have a flood policy, the loss is yours. And flood doesn't only happen in coastal areas — FEMA has historically reported that a meaningful share of paid flood claims, often around or above 25%, come from properties outside designated high-risk zones.

    Coverage

    What this coverage includes

    • Building coverage for the structure, foundation, electrical and plumbing systems, HVAC, and built-in appliances
    • Contents coverage for furniture, inventory, equipment, and other personal property
    • Debris removal from a flood event
    • Loss-avoidance measures — sandbags and pre-emptive protective costs in many policy forms
    • Increased Cost of Compliance under NFIP policies, which helps cover the cost of bringing a substantially damaged building up to current floodplain code

    Who Buys This

    Who typically buys this coverage

    • Property owners with federally backed mortgages in high-risk flood zones — federal law requires it
    • Coastal and waterfront property owners even outside mandatory zones
    • Businesses in low-lying urban areas subject to flash flooding and stormwater backup
    • Properties downstream of dams, rivers, or with poor drainage
    • Commercial tenants with significant inventory or equipment values, since the landlord's flood policy (if any) covers only the building

    Why Koosh

    Why Koosh Insurance

    Flood is a specialty line that most generalist agents either don't write often or don't write well. We treat it as core.

    NFIP and private markets, side by side — no bias toward one source, we quote what gives the client the best outcome.

    Elevation certificate review — a correct EC can dramatically reduce your premium in a designated zone.

    Waiting-period planning — we build flood into renewal calendars so coverage is in place well ahead of storm season.

    Coastal underwriting experience — our team has placed flood on properties across the highest-exposure markets in the country.

    Coordination with property and wind — three policies that need to work together at claim time, with deductibles and triggers aligned so a single storm doesn't expose three different gaps.

    FAQ

    Frequently asked questions

    NFIP is the federal government's flood insurer, with standardized forms and capped limits ($500,000 building / $500,000 contents on commercial). Private flood markets often offer higher limits, broader coverage including loss of rents and business interruption, and sometimes lower pricing. We quote both whenever both are available.

    A meaningful share of paid flood claims come from outside high-risk zones. Stormwater, flash floods, and infrastructure failures don't respect FEMA flood maps. The premium for a non-zone property is usually low enough that it's worth carrying.

    NFIP policies have a standard 30-day waiting period. Private flood waiting periods vary. Don't try to buy flood when a storm is already forming — it won't bind in time. We push clients to put it in place at renewal, not at warning.

    No. Flood specifically means rising surface water from external sources. Internal water damage falls under your property policy.

    Private market. Several specialty carriers now write flood at competitive rates and will often pick up risks NFIP has rate-graded out of. We'll shop it.

    Not under standard NFIP. Some private flood policies include or offer business interruption — a meaningful difference for restaurants, retailers, and any business that can't operate while drying out and rebuilding.
