After a big storm, many Condo owners learn the same thing the hard way: wind and flood are usually two different coverages, often on two different policies, with two different deductibles. Here’s a plain-language map of who usually covers what — and what to check before the next storm.
Education only — not insurance or legal advice. Updated October 7, 2026.
Most standard property policies — including a typical association master policy and a typical HO-6 unit owner policy — are built to cover sudden events like fire, wind, hail, and many kinds of internal water leaks. They generally exclude flood: rising or surface water that comes from outside, such as an overflowing river, heavy rain that pools and enters the building, or storm surge from the ocean.
Flood coverage is usually purchased separately, either through the federal National Flood Insurance Program (NFIP) or through a private flood insurer. Wind, on the other hand, is often included in the property policy — though in some coastal areas wind may be excluded and written on a separate policy, and many policies carry a special hurricane or named-storm deductible.
This isn’t only a coastal issue. Hurricanes and storm surge get the headlines in Florida and along the Gulf and Atlantic coasts, but flooding can also come from river overflow, snowmelt, flash floods, or a few hours of very heavy rain almost anywhere. Wind damage from tornadoes, severe thunderstorms, and nor’easters is common far from the beach. The questions on this page apply nationwide.
A simplified starting map. The real split depends on your association’s governing documents, the master policy form, your own policy, and state law. Treat this as vocabulary for a conversation with your agent — not a coverage chart for your unit.
Bought by the board, paid through dues. Usually covers the building and common elements.
Bought by you. Covers what the documents assign to owners, plus your belongings and liability.
A separate policy. The association can buy one for the building; you can buy one for your unit and belongings.
The practical takeaway: after a storm, an owner may be dealing with up to three policies — the master, their HO-6, and a flood policy — each with its own deductible and rules. Knowing ahead of time which policies exist, and which ones you’re missing, is most of the battle.
The NFIP offers two main ways flood coverage shows up in a Condo building. Details and current limits are published on FloodSmart.gov, the program’s official consumer site — check there and with your agent, because program rules change.
Your lender may also have a say. If your building is in a high-risk flood zone and you have a federally backed mortgage, the lender will often require flood coverage and may want to see whether the association’s flood policy is adequate before deciding whether you need your own.
In many storm-exposed areas, property policies use a percentage deductible for wind, hurricanes, or named storms instead of a flat dollar amount. The percentage is usually applied to the insured value of the building (or of your coverage), not to the size of the loss — so the dollar amount can be much larger than people expect.
A hypothetical example (made-up numbers for illustration only): suppose a master policy insures a building for $20 million with a 5% named-storm deductible. That deductible would be $1 million. If the association has to fund that amount after a storm, it may pass some or all of it to owners as an assessment. Split across 100 units, that’s $10,000 per unit on average — before anything inside your own unit is repaired under your HO-6 deductible.
Points worth confirming:
Florida and Gulf Coast owners see this most often, but percentage wind and hail deductibles appear in other regions too. Your loss assessment coverage is the piece of your HO-6 that usually connects to this problem — see guide #3: deductible-driven assessments and loss assessment coverage for limits and what to ask.

Big storms rarely cause just one kind of damage. These are the situations where flood vs wind questions usually come up. How they’re handled depends on the exact policy wording, so check your policy and ask your agent.
When both happen. If a storm brings wind damage and flooding, adjusters typically try to separate what wind did from what water did, and each policy pays its own part (if you have it). Some policies contain language about losses with more than one cause. Photos and video taken as soon as it’s safe — showing roof and window damage, water lines on walls, and where water came in — can make that process clearer.
Water or sewer backup — water coming up through drains — is a separate issue again. It’s often excluded from standard HO-6 policies unless you add an endorsement, and it may or may not be treated as flood depending on the cause. See water damage between units in our HO-6 vs master guide for leaks that start inside the building.
Bring your documents and ask these before storm season. Clear answers usually expose the gaps quickly.
Short answers for Condo unit owners. Always verify with your documents and a licensed agent in your state.
Usually not. Standard HO-6 policies generally exclude flood — rising or surface water from outside, including storm surge. Flood is typically bought separately through the NFIP or a private flood insurer. Check your exclusions and ask your agent.
Often yes, for the parts of the unit and belongings your policy insures, subject to your deductible. But in some coastal areas wind may be excluded and written separately, and many policies carry a separate hurricane, named-storm, or wind/hail deductible. Read your declarations page and ask your agent.
Partly at most. An association flood policy such as the NFIP RCBAP generally covers the building and, if purchased, commonly owned contents — not your personal belongings — and its limits may not fully cover the building. Many owners consider a personal flood policy. Ask the board what the master flood policy covers and ask your agent whether you need your own.
Storm surge is generally treated as flood, even when a hurricane causes it, so it usually falls under flood insurance. Wind damage itself — a torn roof, broken windows — is usually handled under the property policy. When both happen, adjusters typically sort damage by cause, so documentation matters.
Usually not in time to help. New NFIP policies generally have a 30-day waiting period, with limited exceptions. Private flood policies set their own waiting periods, and many insurers stop writing or changing policies once a named storm is approaching. Review flood coverage well before storm season.
No. Coverage Gap Report is general education for Condo owners. Rules, forms, and governing documents vary by state, insurer, and association. Verify with your declaration and bylaws, the master policy, your own policy, and a licensed insurance agent in your state.
